    "content": "# CLI & Robot Mode Enhancements\n\n## Overview\n\nThis bead collection focuses on making `cass` more powerful and useful for both\nhuman CLI users and AI agents consuming robot mode output. All improvements are\n**self-contained** (no external APIs, embeddings, or LLM dependencies) and build\non existing Tantivy/SQLite infrastructure.\n\n### Design Philosophy\n\n1. **Robot mode is the API** - AI agents will call `cass search --robot`, so this\n   must be rock-solid, predictable, and well-documented\n2. **CLI should be powerful without TUI** - Users shouldn't need to enter TUI for\n   quick searches; pipe-friendly output matters\n3. **Query language should be expressive** - Boolean operators and field syntax\n   unlock power-user and agent workflows\n4. **Backward compatibility** - Existing robot mode consumers shouldn't break\n\n### Success Criteria\n\n- AI agents can reliably parse all robot mode output\n- Complex queries are expressible in a single command\n- Output is predictable and scriptable\n- No performance regression\n\n---\n\n## Dependency Graph (REVISED)\n\n```\n┌─────────────────────────────────────────────────────────────────────┐\n│                     ALREADY IMPLEMENTED                              │\n│  cre.1: Quiet/Verbose (--quiet, --verbose exist)                    │\n│  cre.7: Date Range Flags (--today, --week, --since, --until exist)  │\n└─────────────────────────────────────────────────────────────────────┘\n\nIndependent beads (can be done in parallel):\n\n    ┌─────────────────┐   ┌─────────────────┐   ┌─────────────────┐\n    │ cre.2: Robot    │   │ cre.3: Human    │   │ cre.9: Diagnose │\n    │ Output Enhance  │   │ Output (--disp) │   │ (health focus)  │\n    └────────┬────────┘   └─────────────────┘   └─────────────────┘\n             │\n             ▼\n    ┌─────────────────┐\n    │ cre.4: Boolean  │ ←── Independent, high value\n    │ Query Operators │\n    └────────┬────────┘\n             │\n             ▼\n    ┌─────────────────┐\n    │ cre.5: Field    │ ←── P2: nice-to-have (--agent/--workspace exist)\n    │ Syntax          │\n    └────────┬────────┘\n             │\n             ▼\n    ┌─────────────────┐\n    │ cre.10: Dynamic │ ←── P3: polish\n    │ Shell Complete  │\n    └─────────────────┘\n\nStandalone beads (no dependencies):\n\n    ┌─────────────────┐   ┌─────────────────┐\n    │ cre.6: Export   │   │ cre.8: Context  │\n    │ (simplified)    │   │ -C (like grep)  │\n    └─────────────────┘   └─────────────────┘\n```\n\n---\n\n## BEAD cre.1: Quiet/Verbose Output Modes\n\n**Priority:** P0 (foundational)\n**Complexity:** Low\n**Dependencies:** None\n**Status:** ✅ MOSTLY IMPLEMENTED\n\n### What Already Exists\n\nThe following flags are already implemented in `src/lib.rs`:\n- `--quiet / -q` - Sets log filter to \"warn\" level\n- `--verbose / -v` - Sets log filter to \"debug\" level (just added)\n\nThe tracing crate already provides `info!`, `debug!`, `warn!` macros that respect\nthe log filter.\n\n### Remaining Work\n\n1. **Verify behavior**: Ensure robot mode outputs clean JSON on stdout with no\n   stderr pollution (except actual errors)\n2. **Update documentation**: Add --verbose to robot-docs output\n3. **Test coverage**: Add tests for output stream behavior\n\n### Subtasks\n\n- [x] cre.1.1: Add --quiet and --verbose to clap args (DONE)\n- [x] cre.1.2: Uses existing tracing macros (info!/debug!/warn!) - DONE\n- [ ] cre.1.3: Verify robot mode stdout/stderr separation\n- [ ] cre.1.4: Update --robot-help to mention --verbose\n- [ ] cre.1.5: Add tests for output stream behavior\n\n---\n\n## BEAD cre.2: Enhanced Robot Mode Output\n\n**Priority:** P0 (critical for AI agents)\n**Complexity:** Medium\n**Dependencies:** None (cre.1 mostly done)\n\n### Background\n\nRobot mode (`--robot`) outputs JSON for programmatic consumption. Current format:\n```json\n{\"query\": \"...\", \"limit\": 10, \"offset\": 0, \"count\": 5, \"hits\": [...]}\n```\n\n### What Already Exists\n\n- `--offset N` and `--limit N` for pagination (already implemented)\n- JSON output with pretty printing\n- Error output as JSON to stderr\n\n### Issues to Address\n\n1. **No JSONL option** for streaming large result sets\n2. **No timing metadata** (elapsed_ms)\n3. **No indication of wildcard fallback** being used\n\n### Requirements (REVISED - backward compatible)\n\n1. **Format options**: `--robot-format json|jsonl|compact`\n   - `json`: Current behavior (default, unchanged)\n   - `jsonl`: One JSON object per line (streaming-friendly)\n   - `compact`: Current structure, minimal whitespace\n\n2. **Optional metadata**: `--robot-meta` flag adds extra fields\n   ```json\n   {\n     \"query\": \"...\",\n     \"limit\": 10,\n     \"offset\": 0,\n     \"count\": 5,\n     \"elapsed_ms\": 45,           // NEW (only with --robot-meta)\n     \"wildcard_fallback\": false, // NEW (only with --robot-meta)\n     \"hits\": [...]\n   }\n   ```\n   Note: Fields added at top level, not wrapped in \"meta\" to avoid breaking change.\n\n3. **JSONL format**: Each result on its own line\n   ```\n   {\"_meta\": {\"query\": \"...\", \"count\": 5, \"elapsed_ms\": 45}}\n   {\"score\": 0.95, \"agent\": \"claude\", ...}\n   {\"score\": 0.87, \"agent\": \"codex\", ...}\n   ```\n   First line is metadata (prefixed with `_meta` key), then each hit.\n\n**REMOVED** (not worth complexity):\n- `--fields` flag - agents can filter JSON themselves; adds parsing complexity\n- Metadata envelope wrapper - would break existing consumers\n\n### Implementation Notes\n\n```rust\n#[derive(clap::ValueEnum, Default)]\nenum RobotFormat {\n    #[default]\n    Json,    // Pretty JSON (current)\n    Jsonl,   // Streaming, one object per line\n    Compact, // Single-line JSON\n}\n\n// In search output:\nif robot_meta {\n    payload[\"elapsed_ms\"] = elapsed.as_millis();\n    payload[\"wildcard_fallback\"] = wildcard_fallback;\n}\n```\n\n### Subtasks\n\n- [ ] cre.2.1: Add --robot-format enum (json, jsonl, compact)\n- [ ] cre.2.2: Add --robot-meta flag for extended metadata\n- [ ] cre.2.3: Implement JSONL streaming output with _meta header\n- [ ] cre.2.4: Implement compact (minified) JSON output\n- [ ] cre.2.5: Track and report elapsed_ms in robot output\n- [ ] cre.2.6: Track and report wildcard_fallback in robot output\n- [ ] cre.2.7: Update --robot-help with new options\n- [ ] cre.2.8: Add tests for each format\n\n---\n\n## BEAD cre.3: Human-Readable CLI Output Modes\n\n**Priority:** P1\n**Complexity:** Medium\n**Dependencies:** None (independent of robot mode)\n\n### Background\n\nUsers shouldn't need to enter TUI for quick searches. A readable CLI output mode\nenables workflows like:\n```bash\ncass search \"auth bug\" --display table | head -20\ncass search \"config\" --display lines | wc -l\ncass search \"error\" --display markdown >> notes.md\n```\n\n### What Already Exists\n\n- Basic text output format (score/agent/workspace/snippet)\n- `--color auto|always|never` flag\n\n### Requirements (REVISED - use --display to avoid conflict with --robot-format)\n\n1. **Flag name**: `--display` (not `--format`, which is for robot mode)\n\n2. **Default format**: Current behavior (separator lines + multi-field output)\n\n3. **Table format**: `--display table`\n   ```\n   SCORE  AGENT   WORKSPACE            TITLE\n   0.95   claude  /home/user/project   Fix auth flow\n   0.87   codex   /home/user/other     Refactor login\n   ```\n\n4. **Lines format**: `--display lines` (compact, one-liner per result)\n   ```\n   [0.95] claude:/home/user/project \"Fix auth flow\" - First 60 chars...\n   ```\n\n5. **Markdown format**: `--display markdown`\n   ```markdown\n   ## Search: \"auth bug\"\n\n   ### Fix auth flow\n   - **Agent:** claude\n   - **Score:** 0.95\n   - **Path:** /home/user/project/.claude/...\n\n   > Snippet text here...\n   ```\n\n6. **Terminal width awareness**: Auto-truncate to fit terminal\n\n### Implementation Notes\n\n```rust\n#[derive(clap::ValueEnum, Default)]\nenum DisplayFormat {\n    #[default]\n    Default, // Current separator-based format\n    Table,   // Aligned columns\n    Lines,   // One-liner per result\n    Markdown, // For documentation\n}\n\n// Add to search command\n#[arg(long, value_enum, default_value_t = DisplayFormat::Default)]\ndisplay: DisplayFormat,\n```\n\nReuse `contextual_snippet` from TUI for snippet generation.\n\n### Subtasks\n\n- [ ] cre.3.1: Add --display enum (default, table, lines, markdown)\n- [ ] cre.3.2: Implement table formatter with column width calculation\n- [ ] cre.3.3: Implement lines (compact one-line) formatter\n- [ ] cre.3.4: Implement markdown formatter\n- [ ] cre.3.5: Auto-detect terminal width for truncation\n- [ ] cre.3.6: Ensure --display is ignored when --robot is set\n- [ ] cre.3.7: Add tests for each format\n\n---\n\n## BEAD cre.4: Boolean Query Operators\n\n**Priority:** P1 (high value for power users and agents)\n**Complexity:** Medium-High (requires proper parser)\n**Dependencies:** None\n\n### Background\n\nCurrent query handling in `sanitize_query` strips all non-alphanumeric characters\nexcept `*`. This prevents boolean expressions. Tantivy supports boolean queries\nnatively; we just need to parse and construct them.\n\n### Requirements\n\n1. **AND operator**: `auth AND login` (both terms required)\n   - Implicit AND is default for multiple terms (current behavior)\n   - Explicit AND for clarity\n\n2. **OR operator**: `error OR exception` (either term)\n\n3. **NOT operator**: `config NOT deprecated`\n   - Also support `-term` syntax: `config -deprecated`\n\n4. **Grouping**: `(auth OR login) AND error`\n\n5. **Quoted phrases**: `\"exact phrase match\"`\n   - Use Tantivy PhraseQuery\n\n6. **Backward compatibility**: Simple queries work unchanged\n\n### Implementation Notes\n\nCreate a proper query parser using recursive descent or Pratt parsing.\nConsider the `logos` crate for lexing. The output is Tantivy `Box<dyn Query>`.\n\n**Query Grammar:**\n```\nquery     = or_expr\nor_expr   = and_expr (OR and_expr)*\nand_expr  = unary_expr (AND? unary_expr)*  // AND is implicit between terms\nunary_expr = NOT? primary\nprimary   = TERM | PHRASE | WILDCARD | '(' query ')'\nTERM      = [a-zA-Z0-9_]+\nPHRASE    = '\"' [^\"]+ '\"'\nWILDCARD  = '*'? TERM '*'?\n```\n\n```rust\nenum ParsedQuery {\n    Term(String),\n    Phrase(Vec<String>),\n    And(Box<ParsedQuery>, Box<ParsedQuery>),\n    Or(Box<ParsedQuery>, Box<ParsedQuery>),\n    Not(Box<ParsedQuery>),\n    Wildcard(WildcardPattern),\n}\n\nfn parse_query(input: &str) -> Result<ParsedQuery, QueryParseError>;\nfn to_tantivy_query(parsed: &ParsedQuery, schema: &Schema) -> Box<dyn Query>;\n```\n\n### Subtasks\n\n- [ ] cre.4.1: Design and document query grammar\n- [ ] cre.4.2: Implement lexer/tokenizer for query string\n- [ ] cre.4.3: Implement recursive descent parser\n- [ ] cre.4.4: Implement phrase query parsing (\"quoted text\")\n- [ ] cre.4.5: Implement NOT and -term parsing\n- [ ] cre.4.6: Implement grouping with parentheses\n- [ ] cre.4.7: Convert ParsedQuery to Tantivy BooleanQuery\n- [ ] cre.4.8: Preserve existing wildcard support (*term*)\n- [ ] cre.4.9: Add comprehensive parser tests (20+ cases)\n- [ ] cre.4.10: Update help text with query syntax docs\n\n---\n\n## BEAD cre.5: Field-Specific Search Syntax\n\n**Priority:** P2 (nice-to-have - CLI flags already cover main use cases)\n**Complexity:** Medium\n**Dependencies:** cre.4 (builds on boolean parser)\n\n### Background\n\nUsers currently filter by agent/workspace via separate flags (`--agent`, `--workspace`).\nInline syntax like `agent:claude` is more ergonomic for complex queries but is\n**not essential** since the flags work fine.\n\n### What Already Exists\n\n- `--agent <slug>` flag for filtering by agent\n- `--workspace <path>` flag for filtering by workspace\n\n### When This Becomes Valuable\n\nThe inline syntax is mainly useful when combined with boolean operators:\n```bash\ncass search \"agent:claude AND (auth OR login)\"\ncass search \"(agent:claude OR agent:codex) AND error\"\n```\n\nWithout boolean operators (cre.4), field syntax is redundant with existing flags.\n\n### Requirements (simplified)\n\n1. **Field prefixes**: `field:value` syntax\n   - `agent:claude` - filter by agent\n   - `workspace:/path` - filter by workspace path\n   - `title:foo` - search only in title field\n   - `content:bar` - search only in content field\n\n2. **Negation**: `-agent:codex` (exclude agent)\n\n3. **Integration with boolean operators**:\n   `agent:claude AND (auth OR login)`\n\n**DEFERRED** (add complexity, limited value):\n- Multiple values (`agent:claude,codex`) - just use OR\n- Wildcards in values - use existing * syntax\n- File pattern matching - too niche\n\n### Implementation Notes\n\nIntegrate into the boolean parser from cre.4 rather than extracting beforehand.\n\n```rust\n// Extend ParsedQuery enum:\nenum ParsedQuery {\n    // ... existing variants ...\n    Field { name: String, value: String, negated: bool },\n}\n```\n\n### Subtasks\n\n- [ ] cre.5.1: Define supported field names (agent, workspace, title, content)\n- [ ] cre.5.2: Extend lexer to recognize field:value tokens\n- [ ] cre.5.3: Extend parser to handle field prefixes\n- [ ] cre.5.4: Handle negated field prefixes (-agent:)\n- [ ] cre.5.5: Convert field nodes to Tantivy TermQuery\n- [ ] cre.5.6: Add tests for field syntax\n- [ ] cre.5.7: Document field syntax in help\n\n---\n\n## BEAD cre.6: Conversation Export\n\n**Priority:** P2\n**Complexity:** Low\n**Dependencies:** None (standalone feature)\n\n### Background\n\nUsers want to export conversations for documentation, sharing, or archival.\nCurrently must view in TUI or parse JSON output manually.\n\n### Requirements (simplified - single export first)\n\n1. **Export command**: `cass export <source-path>`\n   - Takes a source_path from search results\n   - Outputs to stdout by default\n\n2. **Output flag**: `--output file.md` writes to file instead of stdout\n\n3. **Formats**: `--format markdown|text|json`\n   - `markdown` (default): Role headers, code blocks preserved\n   - `text`: Plain text, no formatting\n   - `json`: Raw JSON structure\n\n4. **Markdown output**:\n   ```markdown\n   # Conversation: Fix authentication bug\n\n   **Agent:** claude\n   **Workspace:** /home/user/myproject\n   **Date:** 2024-01-15 14:30\n\n   ---\n\n   ## User\n\n   I need help fixing the auth bug...\n\n   ## Assistant\n\n   I'll help you fix that. Let me look at the code...\n\n   ```python\n   def authenticate(user):\n       ...\n   ```\n   ```\n\n5. **Robot mode**: `cass export <path> --robot` outputs JSON\n\n**DEFERRED** (add later if needed):\n- Batch export (`--all --output-dir`) - adds complexity\n- Template customization - YAGNI\n\n### Implementation Notes\n\nReuse conversation loading from existing connectors and SQLite storage.\n\n```rust\n// In Commands enum:\nExport {\n    path: PathBuf,\n    #[arg(long)]\n    output: Option<PathBuf>,\n    #[arg(long, value_enum, default_value_t = ExportFormat::Markdown)]\n    format: ExportFormat,\n    #[arg(long)]\n    robot: bool,\n}\n```\n\n### Subtasks\n\n- [ ] cre.6.1: Add export subcommand to CLI\n- [ ] cre.6.2: Implement conversation loading by source path\n- [ ] cre.6.3: Implement markdown formatter for conversations\n- [ ] cre.6.4: Implement text (plain) formatter\n- [ ] cre.6.5: Handle code block detection/preservation\n- [ ] cre.6.6: Add --output flag for file output\n- [ ] cre.6.7: Add --robot flag for JSON output\n- [ ] cre.6.8: Add tests for export formats\n\n---\n\n## BEAD cre.7: Date Range CLI Flags\n\n**Priority:** N/A\n**Complexity:** N/A\n**Dependencies:** N/A\n**Status:** ✅ ALREADY IMPLEMENTED\n\n### What Already Exists (in src/lib.rs lines 134-150)\n\nThe following date filtering flags are already implemented:\n\n1. **Shortcut flags**:\n   - `--today` - Filter to today only\n   - `--yesterday` - Filter to yesterday only\n   - `--week` - Filter to last 7 days\n   - `--days N` - Filter to last N days\n\n2. **Absolute dates**:\n   - `--since YYYY-MM-DD` or `--since YYYY-MM-DDTHH:MM:SS`\n   - `--until YYYY-MM-DD` or `--until YYYY-MM-DDTHH:MM:SS`\n\nThe `TimeFilter` struct and `parse_datetime_str` function handle ISO 8601 parsing.\n\n### Potential Future Enhancement\n\nIf natural language parsing is desired (\"3 days ago\", \"last week\"), that would\nbe a new feature. But the current implementation covers 95% of use cases.\n\n### Subtasks\n\n- [x] cre.7.1: Add --since and --until CLI flags (DONE)\n- [x] cre.7.2: Implement ISO 8601 date parsing (DONE)\n- [x] cre.7.3: Add --today, --week, --days shortcuts (DONE)\n- [x] cre.7.4: Integrate with SearchFilters (DONE)\n- [ ] cre.7.5: (OPTIONAL) Natural language date parsing\n- [ ] cre.7.6: Include resolved dates in robot mode metadata (part of cre.2)\n\n---\n\n## BEAD cre.8: Search Context (-C)\n\n**Priority:** P2\n**Complexity:** Medium\n**Dependencies:** None (standalone feature)\n\n### Background\n\nLike `grep -C`, users want to see messages before/after the match to understand\ncontext. Current results show only the matching message.\n\n### Requirements\n\n1. **Context flag**: `--context N` or `-C N`\n   - Show N messages before and after match\n\n2. **Directional**: `--before N` (`-B`), `--after N` (`-A`)\n\n3. **Output format**: Clearly delineate context vs match\n   ```\n   [context] User: Earlier message...\n   [context] Assistant: Previous response...\n   [MATCH]   User: The matching message\n   [context] Assistant: Following response...\n   ```\n\n4. **Robot mode**: Include context messages in output\n   ```json\n   {\n     \"match\": {...},\n     \"context_before\": [...],\n     \"context_after\": [...]\n   }\n   ```\n\n### Performance Consideration\n\nLoading full conversations for every result could be slow.

Lazy load context only when --context is specified\n\nRecommended: Option 3 (only load when -C flag is present)\n\n### Implementation Notes\n\nUse `msg_idx` field from SearchHit to locate match position, then load\nsurrounding messages from SQLite.\n\n```rust\n// Add to search command:\n#[arg(short = 'C', long)]\ncontext: Option<usize>,\n\n#[arg(short = 'B', long)]\nbefore: Option<usize>,\n\n#[arg(short = 'A', long)]\nafter: Option<usize>,\n```\n\n### Subtasks\n\n- [ ] cre.8.1: Add -C, -B, -A flags to search command\n- [ ] cre.8.2: Implement context loading from SQLite by conversation_id + msg_idx\n- [ ] cre.8.3: Extract context window around match\n- [ ] cre.8.4: Format context in CLI text output\n- [ ] cre.8.5: Format context in robot mode JSON\n- [ ] cre.8.6: Handle edge cases (match at start/end of conversation)\n- [ ] cre.8.7: Add tests for context extraction\n\n---\n\n## BEAD cre.9: Diagnostic Mode\n\n**Priority:** P2\n**Complexity:** Low\n**Dependencies:** None\n\n### Background\n\nWhen things go wrong, users need visibility into index health. The existing\n`cass stats` command shows counts, but doesn't check health or detect issues.\n\n### Differentiation from `cass stats`\n\n| Feature                | `cass stats`          | `cass diagnose`       |\n|------------------------|----------------------|----------------------|\n| Document counts        | ✅                    | ✅                    |\n| Agent breakdown        | ✅                    | ✅                    |\n| Workspace breakdown    | ✅                    | ❌                    |\n| Index readable check   | ❌                    | ✅ **NEW**            |\n| Schema version match   | ❌                    | ✅ **NEW**            |\n| Connector detection    | ❌                    | ✅ **NEW**            |\n| Issue detection        | ❌                    | ✅ **NEW**            |\n| Fix suggestions        | ❌                    | ✅ **NEW**            |\n| Disk usage             | ❌                    | ✅ **NEW**            |\n\n**Key insight**: `stats` is for \"how much data do I have?\" while `diagnose` is\nfor \"is everything working correctly?\"\n\n### Requirements\n\n1. **Diagnose command**: `cass diagnose`\n\n2. **Health checks** (the main value):\n   - Can Tantivy index be opened?\n   - Can SQLite database be opened?\n   - Does schema version match expected?\n   - Are connector roots accessible?\n   - Any orphaned data (index vs SQLite mismatch)?\n\n3. **Disk usage**:\n   - Index size on disk\n   - SQLite file size\n   - Total data directory size\n\n4. **Issue detection with suggestions**:\n   ```\n   ⚠️  ISSUE: Schema version mismatch (expected v4, found v3)\n   💡 FIX: Run `cass index --full --force-rebuild` to rebuild index\n\n   ⚠️  ISSUE: Claude Code directory not found (~/.claude)\n   💡 FIX: This is normal if you don't use Claude Code\n   ```\n\n5. **Robot mode**: `cass diagnose --robot` outputs JSON\n\n### Implementation Notes\n\n```rust\n#[derive(Serialize)]\nstruct DiagnosticReport {\n    status: DiagnosticStatus, // Healthy, Warning, Error\n    checks: Vec<HealthCheck>,\n    disk_usage: DiskUsage,\n    connectors: Vec<ConnectorStatus>,\n    issues: Vec<DiagnosticIssue>,\n}\n\n#[derive(Serialize)]\nstruct DiagnosticIssue {\n    severity: Severity, // Warning, Error\n    message: String,\n    suggestion: Option<String>,\n}\n```\n\n### Subtasks\n\n- [ ] cre.9.1: Add diagnose subcommand\n- [ ] cre.9.2: Implement index health check (can open?)\n- [ ] cre.9.3: Implement SQLite health check (can open?)\n- [ ] cre.9.4: Implement schema version check\n- [ ] cre.9.5: Implement connector root detection\n- [ ] cre.9.6: Implement disk usage calculation\n- [ ] cre.9.7: Format human-readable output with colors\n- [ ] cre.9.8: Format robot mode JSON output\n- [ ] cre.9.9: Add fix suggestions for common issues\n\n---\n\n## BEAD cre.10: Enhanced Shell Completions\n\n**Priority:** P3\n**Complexity:** Medium\n**Dependencies:** cre.5\n\n### Background\n\nclap_complete provides static completions. Context-aware completions (agent names,\nworkspace paths) would significantly improve CLI UX.\n\n### Requirements\n\n1. **Dynamic agent completion**: Complete agent names from index\n   ```bash\n   cass search agent:<TAB>\n   # claude  codex  gemini  cline\n   ```\n\n2. **Workspace completion**: Complete known workspace paths\n   ```bash\n   cass search workspace:<TAB>\n   # /home/user/project1  /home/user/project2\n   ```\n\n3. **Field name completion**: Complete valid field prefixes\n   ```bash\n   cass search <TAB>\n   # agent:  workspace:  title:  content:  file:\n   ```\n\n4. **Support major shells**: bash, zsh, fish\n\n### Implementation Notes\n\nImplement a `cass completions --generate-dynamic` that queries the index\nand outputs completion data. Shell scripts source this.\n\nFor zsh, use `_describe` with dynamically fetched values.\n\n### Subtasks\n\n- [ ] cre.10.1: Implement agent name retrieval from index\n- [ ] cre.10.2: Implement workspace path retrieval from index\n- [ ] cre.10.3: Create dynamic completion data generator\n- [ ] cre.10.4: Implement bash completion script with dynamic lookup\n- [ ] cre.10.5: Implement zsh completion script with dynamic lookup\n- [ ] cre.10.6: Implement fish completion script with dynamic lookup\n- [ ] cre.10.7: Document shell completion setup\n- [ ] cre.10.8: Add caching for completion data (avoid slow lookups)\n\n---\n\n## Implementation Order (REVISED)\n\nBased on the review, many features already exist. Here's the updated plan:\n\n### Already Done ✅\n- **cre.1**: Quiet/Verbose modes (--quiet, --verbose exist)\n- **cre.7**: Date range flags (--today, --week, --since, --until exist)\n\n### Phase 1: Robot Mode Polish (cre.2)\n- Add --robot-format (json, jsonl, compact)\n- Add --robot-meta for extended metadata\n- Track elapsed_ms and wildcard_fallback\n- **Value**: Highest impact for AI agents\n\n### Phase 2: Boolean Queries (cre.4)\n- Implement boolean parser (AND, OR, NOT, phrases)\n- **Value**: Unlocks power-user and agent workflows\n- **Complexity**: Medium-high, but foundational\n\n### Phase 3: Human CLI Formats (cre.3)\n- Add --display (table, lines, markdown)\n- **Value**: Users don't need TUI for quick searches\n\n### Phase 4: Diagnostics (cre.9)\n- Add `cass diagnose` with health checks\n- **Value**: Self-service troubleshooting\n\n### Phase 5: Context & Export (cre.8, cre.6)\n- Add -C for context (like grep)\n- Add `cass export` for markdown export\n- **Value**: Better understanding and documentation\n\n### Phase 6: Advanced Query (cre.5)\n- Add field:value inline syntax\n- **Value**: Ergonomic when combined with boolean operators\n\n### Phase 7: Polish (cre.10)\n- Dynamic shell completions\n- **Value**: Nice DX improvement\n\n---\n\n## Testing Strategy\n\n1. **Unit tests** for query parsing, formatters, health checks\n2. **Integration tests** for CLI flag combinations\n3. **Snapshot tests** for output format consistency\n4. **Robot mode contract tests** ensuring JSON schema stability\n5. **E2E tests** for diagnose command\n\n---\n\n## Documentation Updates Required\n\n- [ ] Update --robot-help with --robot-format and --robot-meta\n- [ ] Update README.md with boolean query syntax\n- [ ] Add QUERY_SYNTAX.md with full documentation\n- [ ] Update man page\n- [ ] Add examples to --help output for new flags\n\n"

Nothing ever reads the backups_dir to prune.

Which standard PRAGMAs does frankensqlite actually support?\\n   - Test each one: journal_mode, synchronous, wal_autocheckpoint, temp_store, cache_size, foreign_keys\\n   - Document: does it execute without error? Does it actually change behavior?\\n2. Does PRAGMA user_version work? (cass uses for schema versioning)\\n3. What is frankensqlite's equivalent of WAL mode?\\n   - With MVCC, is journal_mode irrelevant?\\n   - Is synchronous relevant for MemDatabase snapshots?\\n4. What happens when you set a PRAGMA it doesn't support? (error? silent ignore? panic?)\\n5. Does busy_timeout have meaning with MVCC? (With BEGIN CONCURRENT, the retry strategy is different)\\n6.

This is CONFIRMED as not existing — frankensearch currently only has file-backed FSVI (memory-mapped) via VectorIndex.\\n\\nWHY THIS IS NEEDED (not just FSVI mmap):\\n- Cass TUI loads ALL embeddings into RAM at startup for deterministic sub-millisecond search\\n- FSVI mmap has page fault latency on first access (cold paths), unacceptable for TUI responsiveness\\n- Cass's current TwoTierIndex in two_tier_search.rs stores f16 vectors in a flat Vec<half::f16> for guaranteed-resident brute-force scan\\n- frankensearch's VectorIndex uses MmapMut (file-backed), which can page fault\\n- InMemoryVectorIndex would give frankensearch a fully-resident search path\\n\\nVERIFIED CURRENT STATE:\\n- VectorIndex struct has: path, data (MmapMut), metadata, records_offset, strings_offset, vectors_offset, wal_entries\\n- TwoTierIndex wraps two VectorIndex instances (fast + quality), both file-backed\\n- TwoTierIndex.search_fast() is SYNC and takes &[f32] query vectors (converts internally)\\n- No in-memory alternative exists anywhere in frankensearch\\n\\nDESIGN:\\n- New struct InMemoryVectorIndex that stores vectors in contiguous resident memory (not mmap)\\n- Constructor: InMemoryVectorIndex::from_fsvi(path) — reads FSVI file entirely into heap-allocated memory\\n- Constructor: InMemoryVectorIndex::from_vectors(doc_ids: Vec<String>, vectors: Vec<Vec<f32>>, dimension: usize)\\n- Search API: search_top_k(query: &[f32], k: usize, filter: Option<&dyn SearchFilter>) -> SearchResult<Vec<VectorHit>>\\n- Internal storage: f16 quantized row-major flat layout (matching cass's current approach for 50% memory savings)\\n- Brute-force dot product with optional Rayon parallelism above threshold (10K+ vectors)\\n- Must implement same VectorHit result type as file-backed VectorIndex\\n\\nALSO NEEDED: InMemoryTwoTierIndex that wraps two InMemoryVectorIndex instances (fast + quality) with the same search_fast() / quality_scores_for_hits() API as TwoTierIndex.\\n\\nPERFORMANCE REQUIREMENTS:\\n- Must match or exceed cass's current two_tier_search.rs in-memory search latency\\n- f16 quantization: store as f16, convert to f32 only during dot product\\n- Parallel threshold: 10,000 vectors (matching frankensearch's FSVI default)\\n- Binary heap top-k selection (matching cass's current approach)\\n\\nFILES TO CREATE:

Comprehensive unit tests for the frankensqlite compat adapter layer and migration framework.\\n\\nTEST PLAN:\\n\\n1. PARAMS MACRO:\\n   - params![1i64, \\\\\\\"hello\\\\\\\", 3.14f64] produces correct SqliteValue array\\n   - params![] produces empty array\\n   - params![None::<i64>] produces SqliteValue::Null\\n   - params![true] produces SqliteValue::Integer(1)\\n   - params![false] produces SqliteValue::Integer(0)\\n   - params![vec![1u8, 2, 3]] produces SqliteValue::Blob\\n\\n2. FROM IMPLS:\\n   - From<bool>: true → Integer(1), false → Integer(0)\\n   - From<Option<i64>>: Some(42) → Integer(42), None → Null\\n   - From<u32>, From<u64>: correct conversion (with overflow check for u64 > i64::MAX)\\n   - From<usize>: correct conversion\\n\\n3. TYPED ROW EXTRACTION (RowExt):\\n   - row.get_typed::<i64>(0) on Integer column → correct value\\n   - row.get_typed::<String>(1) on Text column → correct value\\n   - row.get_typed::<Option<i64>>(2) on NULL → None\\n   - row.get_typed::<f64>(0) on Integer column → type coercion (or error)\\n   - row.get_typed::<i64>(99) → index out of bounds error\\n   - row.get_typed::<bool>(0) on Integer(1) → true, Integer(0) → false\\n\\n4. QUERY WITH CLOSURE (ConnectionExt):\\n   - query_row_map: returns closure-transformed value\\n   - query_map_collect: returns Vec of closure-transformed values\\n   - query_row_map on empty result → QueryReturnedNoRows error\\n   - query_map_collect on empty result → empty Vec (not error)\\n\\n5. EXECUTE_BATCH:\\n   - Multi-statement SQL separated by ';': all statements execute\\n   - SQL with comments (-- and /* */): handled correctly\\n   - Empty string: no-op, no error\\n   - Single statement without ';': executes correctly\\n   - PRAGMA blocks (typical cass usage): all PRAGMAs applied\\n\\n6. TRANSACTION:\\n   - transaction() + commit() → changes persist (verified by re-query)\\n   - transaction() + drop (no commit) → changes rolled back\\n   - execute within transaction → works correctly\\n   - query_row_map within transaction → works correctly\\n   - Error during transaction → clean rollback on drop\\n\\n7. OPTIONAL EXTENSION:\\n   - Ok(value).optional() → Ok(Some(value))\\n   - Err(QueryReturnedNoRows).optional() → Ok(None)\\n   - Err(other_error).optional() → Err(other_error) (passes through)\\n\\n8. OPEN FLAGS:\\n   - open_with_flags(READ_ONLY) → writes fail with appropriate error\\n   - open_with_flags(READ_WRITE | CREATE) → creates new DB\\n   - open_with_flags(READ_WRITE) on existing DB → succeeds\\n\\n9. PARAMS_FROM_ITER:\\n   - params_from_iter(vec![1i64, 2, 3]) → correct Vec<SqliteValue>\\n   - params_from_iter(std::iter::empty()) → empty Vec\\n   - params_from_iter(mixed types via Into<SqliteValue>) → correct conversion\\n\\n10. MIGRATION FRAMEWORK:\\n    - Fresh DB: all migrations applied in order (V1, V2, ..., V13)\\n    - Existing DB at V5: only V6-V13 applied\\n    - Idempotent: running twice applies nothing second time\\n    - Failed migration: rolls back, version unchanged, error reported\\n    - Migration result: applied list, current version, was_fresh flag all correct\\n\\n11. RUSQLITE PARITY (golden test):\\n    - For 10 representative SQL patterns from cass, execute via both rusqlite and compat adapter\\n    - Compare results: row counts, column values, NULL handling\\n    - Patterns: INSERT, SELECT with JOIN, UPDATE, DELETE, UPSERT, GROUP BY + HAVING, FTS5 MATCH, LIKE, subquery\\n\\nFILES: frankensqlite/fsqlite/tests/compat_tests.rs,

Modify search_semantic() in query.rs to optionally use SyncTwoTierSearcher instead of single-tier VectorIndex.search_top_k()\\n2. Add progressive delivery: show fast results immediately in TUI, refine when quality tier completes\\n3. Use SyncSearchIterator for TUI polling: next() returns Phase 1 (fast), then Phase 2 (quality-refined)\\n4. This improves search result quality by blending fast + quality tier scores\\n\\nCURRENT STATE: Production semantic search at query.rs:2280 uses fs_index.search_top_k(&embedding, fetch, fs_filter) — single-tier, no progressive refinement.\\n\\nNEW BEHAVIOR (with this bead):\\n- TUI search calls SyncTwoTierSearcher.search_iter()\\n- Phase 1 (fast): sub-10ms, f16 brute-force, shows results immediately\\n- Phase 2 (quality): 50-200ms, full embedding comparison, re-ranks results\\n- Score blending via frankensearch::blend_two_tier()\\n\\nFEATURE FLAG: Gate behind --progressive-search flag or config option, since this requires both fast AND quality vector indexes.

Each Tool Has Full Daemon Code\\n```rust\\n// In cass/src/daemon/mod.rs (INDEPENDENT copy, not imported from xf)\\npub mod client;\\npub mod core;\\npub mod models;\\npub mod protocol;\\npub mod resource;\\n\\n// Protocol is wire-compatible with xf's daemon\\npub use protocol::{Request, Response, PROTOCOL_VERSION};\\n```\\n\\n### 2. Shared Socket Path\\n```rust\\nfn default_socket_path() -> PathBuf {\\n    // Same path for both tools - enables sharing\\n    let user = std::env::var(\\\"USER\\\").unwrap_or_else(|_| \\\"unknown\\\".into());\\n    PathBuf::from(format!(\\\"/tmp/semantic-daemon-{}.sock\\\", user))\\n}\\n```\\n\\n### 3. First-Come Spawns, Others Connect\\n```rust\\nimpl DaemonClient {\\n    pub async fn connect_or_spawn() -> Result<Self> {\\n        let socket = default_socket_path();\\n        \\n        // Try to connect to existing daemon\\n        if let Ok(client) = Self::connect(&socket).await {\\n            tracing::info!(\\\"Connected to existing daemon\\\");\\n            return Ok(client);\\n        }\\n        \\n        // No daemon running - spawn our own\\n        tracing::info!(\\\"Spawning daemon\\\");\\n        spawn_daemon(&socket).await?;\\n        \\n        // Connect to newly spawned daemon\\n        Self::connect(&socket).await\\n    }\\n}\\n```\\n\\n### 4. Wire-Compatible Protocol\\nBoth tools use identical MessagePack protocol:\\n```rust\\npub enum Request {\\n    Health,\\n    Embed { texts: Vec<String>, model: String, dims: Option<usize> },\\n    Rerank { query: String, documents: Vec<String>, model: String },\\n    Status,\\n    Shutdown,\\n}\\n```\\n\\n## Implementation for cass\\n\\n### File Structure\\n```\\ncass/src/\\n├── daemon/\\n│   ├── mod.rs          # Re-exports\\n│   ├── client.rs       # DaemonClient (connect, embed, rerank)\\n│   ├── core.rs         # ModelDaemon server\\n│   ├── models.rs       # ModelManager, lazy loading\\n│   ├── protocol.rs     # Request/Response types (wire-compatible)\\n│   └── resource.rs     # Memory monitoring, nice/ionice\\n├── search/\\n│   └── semantic.rs     # Uses DaemonClient\\n└── main.rs\\n```\\n\\n### Key Differences from xf\\n\\nThe daemon code is a **copy**, not a dependency:\\n- Same protocol version (wire-compatible)\\n- Same socket path (can share daemon)\\n- Same model loading logic\\n- Independent compilation (no xf dependency)\\n\\n### When Tools Share a Daemon\\n\\nIf user has both xf and cass installed:\\n1. User runs `xf search \\\"query\\\"` → xf spawns daemon\\n2. User runs `cass search \\\"query\\\"` → cass connects to existing daemon\\n3. Both tools share warm models\\n4. Either tool stopping doesn't affect the other (daemon keeps running)\\n\\n### When Tools Run Alone\\n\\nIf user only has cass:\\n1. User runs `cass search \\\"query\\\"` → cass spawns its own daemon\\n2. Works exactly the same, no xf dependency\\n\\n## Unit Tests\\n```rust\\n#[tokio::test]\\nasync fn test_daemon_spawns_independently() {\\n    // cass should be able to spawn daemon without xf\\n    let client = DaemonClient::connect_or_spawn().await.unwrap();\\n    let health = client.health().await.unwrap();\\n    assert!(health.uptime_secs >= 0);\\n}\\n\\n#[tokio::test]\\nasync fn test_connect_to_existing_daemon() {\\n    // Spawn daemon\\n    let _first = DaemonClient::connect_or_spawn().await.unwrap();\\n    \\n    // Second connection should reuse\\n    let second = DaemonClient::connect_or_spawn().await.unwrap();\\n    let health = second.health().await.unwrap();\\n    assert!(health.uptime_secs > 0); // Already running\\n}\\n\\n#[test]\\nfn test_protocol_wire_compatibility() {\\n    // Ensure our protocol matches xf's\\n    let req = Request::Embed {\\n        texts: vec![\\\"test\\\".into()],\\n        model: \\\"all-MiniLM-L6-v2\\\".into(),\\n        dims: None,\\n    };\\n    let bytes = rmp_serde::to_vec(&req).unwrap();\\n    \\n    // This should deserialize with xf's protocol types too\\n    let decoded: Request = rmp_serde::from_slice(&bytes).unwrap();\\n    assert!(matches!(decoded, Request::Embed { .. }));\\n}\\n```\\n\\n## Acceptance Criteria\\n- [ ] cass works without xf installed\\n- [ ] cass daemon is wire-compatible with xf daemon\\n- [ ] Tools share daemon when both installed (same socket)\\n- [ ] First-to-need spawns, others connect\\n- [ ] Fallback to direct inference if daemon unavailable\\n- [ ] Unit tests verify independence\",\"status\":\"closed\",\"priority\":1,\"issue_type\":\"feature\",\"created_at\":\"2026-01-28T05:03:46.175976Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-01-28T17:56:00.001998Z\",\"closed_at\":\"2026-01-28T17:56:00.001918Z\",\"close_reason\":\"Completed daemon module implementation with: protocol.rs (wire-compatible MessagePack), client.rs (UDS client with auto-spawn), core.rs (ModelDaemon server), models.rs (lazy model loading), resource.rs (memory monitoring, nice/ionice).

After completion, cass should contain ZERO connector parsing code — only import and use connectors from FAD.\\n\\nCURRENT STATE: FAD provides installation detection for 16 agents (~400 lines of filesystem probing).

The cache and dedup layers sit ABOVE the frankensearch pipeline — they operate on cass's own result types.\\n\\nVERIFIED STATE:\\n- CachedHit (query.rs:1488): wraps SearchHit + lowercase content + bloom filter\\n- CacheShards (query.rs:1515): LRU cache keyed on query string, values are Vec<CachedHit>\\n- deduplicate_hits(): operates on Vec<SearchHit>, uses content_hash (u64) for dedup\\n- is_tool_invocation_noise(): pattern-based content filtering on String — no type dependency\\n\\nWHAT ACTUALLY NEEDS CHANGING (minimal):\\nThe migration from tantivy to frankensearch does NOT change the SearchHit type. The only changes are:\\n\\n1. QueryCache embedding storage — currently stores Vec<f32> from SyncEmbed. This ALREADY uses frankensearch's SyncEmbed (embedder.rs:21 pub use frankensearch::SyncEmbed as Embedder). No change needed.\\n\\n2. CacheShards invalidation — if SyncTwoTierSearcher (Phase 2 optional enhancement) changes result ordering, cached results would be stale. Add a cache_version field that increments when search backend changes. LOW PRIORITY.\\n\\n3. deduplicate_hits() doc_id parsing — currently parses doc_id format embedded by cass indexer. If frankensearch changes the doc_id format, dedup parser needs updating. But cass controls the doc_id format during indexing, so this is unlikely to change.\\n\\nCONCLUSION: This bead is NEARLY A NO-OP for the core migration. The cache and dedup layers are already compatible with frankensearch because they operate on cass-internal types (SearchHit, CachedHit), not on frankensearch types (VectorHit, ScoredResult).\\n\\nREMAINING WORK (small):\\n- Verify QueryCache.get_embedding() still works after any import changes from uc0qs/ltbab\\n- Add cache_version field for future-proofing (optional)\\n- Run existing search_caching.rs tests to verify no regression\\n\\nFILES TO MODIFY: src/search/query.rs (minimal — verify imports, optionally add cache_version)\",\"status\":\"closed\",\"priority\":2,\"issue_type\":\"task\",\"created_at\":\"2026-02-27T05:22:15.200792Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-02-28T00:59:18.748094Z\",\"closed_at\":\"2026-02-28T00:59:18.748070Z\",\"close_reason\":\"Verified no-op: QueryCache and dedup operate on cass-internal types (SearchHit, CachedHit), not frankensearch types.

This is a debugging escape hatch to definitively rule out degradation as a visual issue.\\n\\n3. **Add telemetry logging**: When degradation level changes, log to stderr (behind a `CASS_DEBUG_DEGRADATION=1` flag) so users can see if and when degradation triggers:\\n   ```\\n   [degradation] Full → SimpleBorders at frame 142 (budget=120ms, actual=135ms)\\n   ```\\n\\n4. **Verify initial render starts at Full**: Check that the very first frame renders at Full degradation (not pre-degraded).\\n\\n## Required Tests\\n\\n### Unit tests:\\n1. `test_degradation_initial_level_is_full` — Construct a new CassApp, verify the first frame's degradation level is Full (not pre-degraded).\\n2. `test_degradation_env_override` — Set CASS_NO_DEGRADATION=1, verify degradation is always Full regardless of frame time.\\n3. `test_degradation_level_strips_borders` — At SimpleBorders level, verify view() uses BorderType::Square (not Rounded).\\n4. `test_degradation_level_strips_color` — At NoStyling level, verify view() uses `plain` style (not themed).\\n5. `test_degradation_level_strips_all` — At EssentialOnly level, verify view() uses Borders::NONE.\\n\\n### E2E validation:\\n6. `test_no_degradation_with_normal_data` — Render a screen with 20 results at 120×40 terminal size. Verify degradation stays at Full for all frames (the budget should never be exceeded with normal data on modern hardware).\\n\\n## Considerations\\n- The Inspector cockpit (Ctrl+Shift+I → Budget tab) already shows frame timing. This task adds ENV-based overrides and stderr logging for headless/automated debugging.\\n- If verification confirms degradation never triggers on normal terminals, this task is largely documentation.

E2E logging to shell test scripts\",\"description\":\"## Priority 2: Standardize Shell Script E2E Logging\\n\\n### Current State (CORRECTED)\\n\\n**scripts/lib/e2e_log.sh** exists as the standard library.\\n\\n| Script | Status |\\n|--------|--------|\\n| multi_machine_sync.sh | Uses e2e_log.sh ✓ |\\n| cli_flow.sh | Has OWN JSONL logging (target/e2e-cli/run_*/run.jsonl) |\\n| semantic_index.sh | Has OWN JSONL logging (target/e2e-semantic/run_*/run.jsonl) |\\n| daemon_fallback.sh | Wrapper → cass_daemon_e2e.sh (has own logging) |\\n| sources_sync.sh | EMPTY FILE (0 bytes) - needs implementation |\\n\\n### The Real Challenge\\ncli_flow.sh, semantic_index.sh, and cass_daemon_e2e.sh already have sophisticated custom JSONL logging:\\n- Custom RUN_ID generation\\n- Custom directory structure (target/e2e-*/run_${timestamp}/)\\n- Custom JSONL format\\n\\n### Options\\n\\n**Option A (Recommended): Keep custom, add compatibility layer**\\n- Leave existing implementations (they work)\\n- Add a post-processing step to convert their JSONL to standard format\\n- OR add a wrapper function that writes to BOTH formats\\n\\n**Option B: Full migration to e2e_log.sh**\\n- Replace custom logging with e2e_log.sh calls\\n- Risk: May break existing functionality\\n- Benefit: True standardization\\n\\n### Recommended Implementation (Option A)\\n\\n1. **sources_sync.sh**: Implement from scratch using e2e_log.sh (it's empty anyway)\\n\\n2. **For existing scripts**: Add compatibility by sourcing e2e_log.sh AND keeping existing logging:\\n```bash\\n# At top of cli_flow.sh\\nsource \\\"${PROJECT_ROOT}/scripts/lib/e2e_log.sh\\\"\\ne2e_init \\\"shell\\\" \\\"cli_flow\\\"\\ne2e_run_start\\n\\n# Keep existing custom logging, just ADD e2e_log.sh calls at key points\\n```\\n\\n3. **Create aggregation script** that merges:\\n   - test-results/e2e/*.jsonl (standard location)\\n   - target/e2e-*/run_*/run.jsonl (custom locations)\\n\\n### Files to Modify\\n- scripts/e2e/sources_sync.sh (implement from scratch)\\n- scripts/e2e/cli_flow.sh (add e2e_log.sh, keep custom)\\n- scripts/e2e/semantic_index.sh (add e2e_log.sh, keep custom)\\n-

A typical month of sessions is ~50-200MB per machine.\\n   Use `du -sh ~/.local/share/cass/sources/` to check.\\n\\n**Q: Can I sync from machines without SSH config entries?**\\nA: Yes. After wizard setup, manually add to sources.toml:\\n   ```toml\\n   [[sources]]\\n   name = \\\"adhoc-server\\\"\\n   type = \\\"ssh\\\"\\n   host = \\\"user@192.168.1.100\\\"\\n   ```\\n\\n**Q: Do I need cass installed on remote machines?**\\nA: For indexing: yes. For sync-only: no, rsync is sufficient.\\n   Without remote cass, you sync raw files but can't search remotely.\\n\\n**Q: Can I exclude certain paths or patterns?**\\nA: Not yet. Currently all sessions in configured paths are synced.\\n   This is a planned feature.\\n\\n**Q: How do I remove a source?**\\nA: Delete the `[[sources]]` block from sources.toml.\\n   Optionally delete synced data: `rm -rf ~/.local/share/cass/sources/<name>`\\n```\\n\\n## Acceptance Criteria\\n- [ ] clap doc comments complete with examples\\n- [ ] robot-docs section comprehensive\\n- [ ] AGENTS.md updated with setup guide\\n- [ ] Architecture diagram included (ASCII)\\n- [ ] Configuration reference complete\\n- [ ] FAQ section addresses common questions\\n- [ ] All examples work as documented\\n- [ ] Common errors documented with solutions\\n- [ ] Searchable keywords for discoverability\\n\\n## Dependencies\\n- Requires: Setup command implemented (coding_agent_session_search-dbdl)\\n\\nLabels: [docs sources]\",\"status\":\"closed\",\"priority\":2,\"issue_type\":\"task\",\"created_at\":\"2026-01-05T13:10:20.793596Z\",\"created_by\":\"jemanuel\",\"updated_at\":\"2026-01-05T19:55:31.597995Z\",\"closed_at\":\"2026-01-05T19:55:31.597995Z\",\"close_reason\":\"Implemented in commit 60d2f28\",\"source_repo\":\".\",\"compaction_level\":0,\"original_size\":0,\"labels\":[\"docs\",\"sources\"],\"dependencies\":[{\"issue_id\":\"coding_agent_session_search-22j1\",\"depends_on_id\":\"coding_agent_session_search-dbdl\",\"type\":\"blocks\",\"created_at\":\"2026-02-11T06:20:53Z\",\"created_by\":\"import\",\"metadata\":\"{}\",\"thread_id\":\"\"}]}\n{\"id\":\"coding_agent_session_search-22k2\",\"title\":\"P6.14a: Audit remaining mocks/fakes and coverage gaps\",\"description\":\"# P6.14a: Audit remaining mocks/fakes and coverage gaps\\n\\n## Goal\\nProduce an explicit, up-to-date inventory of all mock/fake/stub usage in `src/`, `tests/`, and `scripts/`, plus a gap map for no-mock unit and E2E coverage.\\n\\n## Why\\nThe repo still contains explicit mock/fake code paths (e.g., MockDaemon in `src/search/daemon_client.rs`, fake binaries in `tests/e2e_install_easy.rs`, fake model file in `tests/semantic_integration.rs`, mock probe helpers in `src/sources/index.rs`).

It is called once per VectorHit in each of the 4 semantic collapse loops in query.rs AND once per candidate in the SemanticFilter::matches() trait impl (vector_index.rs:326). For an approximate (HNSW) search with candidate = fetch_limit * ANN_CANDIDATE_MULTIPLIER, matches() runs on every visited node — potentially thousands of times per query, and each invocation re-parses the doc_id.\\n\\nPROPOSED CHANGE:\\nTwo sub-wins:\\n\\n(a) Fast-path parse: doc_ids in cass always start with `\\\"m|\\\"`. Use `str::splitn(9, '|')` instead of `split('|')` + 7x `parts.next()?` and a tail iteration — saves one split step per call.\\n\\n(b) Caching in SemanticFilter::matches: add a tiny `AHashMap<u64, SemanticDocId>` (or `HashMap` with FxHasher) keyed by a cheap hash of doc_id bytes. For ANN filtering, the same node may be visited multiple times during HNSW traversal; even if not, we already re-parse inside the collapse loop after filtering. Instead, make parse_semantic_doc_id return a `&SemanticDocId` from a per-query cache passed alongside the filter.\\n\\nAlternative lower-risk version: parse once per hit (before the collapse loop) and stash the parsed result alongside the VectorHit, so the collapse loop uses the pre-parsed value and never re-parses.\\n\\nEXPECTED WIN:\\nReduces the parse cost from O(hits * loops) to O(hits). Most valuable for approximate search (HNSW) where matches() is called for every visited node, often 10x the number of candidates returned. Speculative estimate: 5-15% improvement in semantic-only search latency for large fetch_limits.\\n\\nVERIFICATION:\\n1. Roundtrip tests in src/search/vector_index.rs:430-476 must pass unchanged (proves the new parser is byte-identical).\\n2. Add a criterion bench: generate 1000 synthetic doc_ids and measure parse throughput — target >3x faster than current.\\n3. End-to-end: `cargo test --test two_tier_search` and `cargo test --lib search::query::` both green.\\n\\nRISK:\\nP2 (speculative) because the actual win depends on how often matches() fires in production ANN filtering — needs a flamegraph or cachegrind run to confirm the hypothesis before committing.

But the install scripts are still pinned to v0.1.64 (the last ratatui build) because the ftui version looks visibly worse despite being technically superior.\\n\\n## Root Cause Analysis (2026-02-08)\\n\\nA deep audit of app.rs (~22K lines), style_system.rs (~1.5K lines), components/theme.rs, and all test snapshots revealed these categories of issue:\\n\\n1. **Half-wired style system**: 5 of 24 semantic style tokens (STYLE_PILL_ACTIVE, STYLE_TAB_ACTIVE, STYLE_TAB_INACTIVE, STYLE_KBD_KEY, STYLE_KBD_DESC) are defined in the stylesheet but NEVER referenced in rendering code. They were designed for visual polish but nobody connected the wires.\\n\\n2. **Theme-blind markdown**: The detail pane creates `MarkdownRenderer::new(MarkdownTheme::default())` at app.rs:4327 and :4390, ignoring the active theme preset (Dark/Light/Catppuccin/Dracula/Nord/HighContrast). Code blocks, headers, bold text all render in hardcoded default colors that clash with the surrounding UI.\\n\\n3. **Incomplete role gutter port**: Only STYLE_ROLE_GUTTER_ASSISTANT is used (app.rs:4214). User, tool, and system gutter styles are defined but never rendered.

Optionally: add 1-char padding around active tab text for the background to be visible (e.g., ` ● Messages ` with leading/trailing space)\\n3. Verify the active tab background doesn't clash with the pane border on any of the 6 presets\\n\\n## Required Tests\\n\\n### Unit tests:\\n1. `test_detail_tab_uses_tab_tokens` — Verify that tab rendering requests STYLE_TAB_ACTIVE / STYLE_TAB_INACTIVE (not STATUS_INFO / TEXT_MUTED).

The better sibling-doctor pattern is to collapse related findings into a small set of root-cause incidents with one primary risk, one evidence trail, and one next safe action. This matters for cass because a single source-pruning or lock condition can create many derived warnings, and users need to know what actually caused the situation before approving any repair.\\n\\nScope: add a root-cause incident model to doctor reports. Each incident should include incident_id, root_cause_kind, severity, affected_asset_classes, archive_risk_level, derived_risk_level, confidence, evidence_check_ids, blocked_actions, safe_next_actions ranked in order, stale_or_unknown_fields, and redacted evidence paths. Incidents should group symptoms such as source-pruned-with-mirror-intact, mirror-missing-with-db-sole-copy, archive-db-unreadable-with-valid-candidate, derived-index-stale-after-db-promotion, semantic-model-missing-lexical-fallback, active-lock-blocking-repair, storage-pressure-derived-cleanup-available, and backup-exclusion-risk. The model must avoid false certainty: when cass cannot prove a root cause, it should say unknown, preserve all evidence, and recommend a non-destructive check or support bundle rather than mutation.\\n\\nAcceptance criteria: robot JSON exposes incidents[] and primary_incident_id with stable ordering and branchable root_cause_kind values. Human output uses incidents to avoid symptom spam and to explain the single best next safe command. Baseline diffs compare incident changes instead of noisy timestamp churn. Health/status may expose only cheap cached incident summaries and must not perform heavy scans. Support bundles include the incident graph plus redacted evidence links.

This is a **semantic correctness** change — the current styles are functionally identical to the dedicated tokens (both resolve to info+bold / text_muted), but using dedicated tokens means a theme designer can later differentiate keyboard keys from status badges without touching rendering code.\\n\\n## Where\\n\\n- **app.rs:~11940** — Call site of `build_styled_hints()`:\\n  ```rust\\n  let kbd_key_s = styles.style(style_system::STYLE_STATUS_INFO);  // ← Should be STYLE_KBD_KEY\\n  let kbd_desc_s = styles.style(style_system::STYLE_TEXT_MUTED);  // ← Should be STYLE_KBD_DESC\\n  let hint_spans = build_styled_hints(&hints_text, kbd_key_s, kbd_desc_s);\\n  ```\\n\\n## Why This Matters (Even Though Current Output Is Identical)\\n- **Semantic correctness**: `STYLE_STATUS_INFO` is for status badges (\\\"● connected\\\"), `STYLE_KBD_KEY` is for keyboard legends (\\\"C-p\\\"). These are conceptually different even though they happen to render the same today.\\n- **Theme extensibility**: A future theme preset (e.g., a terminal-keyboard-focused theme) could make keys render with a distinctive background or border. With generic STATUS_INFO, that would require touching rendering code.\\n- **Dead token cleanup**: Using the dedicated token means `2zxzf` (verify zero dead tokens) passes.\\n\\n## Implementation\\nSingle-line change at the call site:\\n```rust\\n// Before:\\nlet kbd_key_s = styles.style(style_system::STYLE_STATUS_INFO);\\nlet kbd_desc_s = styles.style(style_system::STYLE_TEXT_MUTED);\\n// After:\\nlet kbd_key_s = styles.style(style_system::STYLE_KBD_KEY);\\nlet kbd_desc_s = styles.style(style_system::STYLE_KBD_DESC);\\n```\\n\\n## ALSO: Differentiate the style definitions\\nTo make this change VISUALLY meaningful (not just semantic), update `build_stylesheet()` in style_system.rs to give KBD_KEY a slightly different look — e.g., add a subtle background or use a different weight:\\n```rust\\n// Before (identical to STATUS_INFO):\\nsheet.define(STYLE_KBD_KEY, Style::new().fg(to_packed(resolved.info)).bold());\\n// After (distinct):\\nsheet.define(STYLE_KBD_KEY, Style::new()\\n    .fg(to_packed(resolved.info))\\n    .bg(to_packed(blend(resolved.surface, resolved.info, 0.12)))\\n    .bold());\\n```\\nThis gives keyboard legends a subtle background highlight, making them visually distinct from status info badges and easier to scan in the footer.\\n\\n## Required Tests\\n\\n### Unit tests (add to app.rs #[cfg(test)] module):\\n1. `test_footer_hint_uses_kbd_tokens` — Verify that footer rendering resolves STYLE_KBD_KEY and STYLE_KBD_DESC (not STATUS_INFO/TEXT_MUTED). Mock a StyleContext, call the footer rendering path, and assert the correct token names are requested.\\n2. `test_kbd_key_style_differs_from_status_info` — Build a StyleSheet from each theme preset, verify that STYLE_KBD_KEY differs from STYLE_STATUS_INFO (at least in bg) to confirm they are visually distinct.\\n3. `test_kbd_styles_degrade_gracefully` — At NoStyling degradation level, verify kbd styles fall back to plain.\\n\\n### Snapshot test:\\n4. Update `cassapp_results_wide.snap` to verify the footer hint styling appears correctly in the baseline.\\n\\n## Acceptance\\n- Footer key hints use STYLE_KBD_KEY / STYLE_KBD_DESC tokens\\n- KBD_KEY has a subtle background that distinguishes it from STATUS_INFO\\n- 3 unit tests pass\\n- Snapshot baseline updated\\n- All 6 theme presets render readable footer hints\\n- No clippy warnings\",\"status\":\"closed\",\"priority\":1,\"issue_type\":\"task\",\"created_at\":\"2026-02-08T19:30:41.425819Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-02-08T20:22:03.007153Z\",\"closed_at\":\"2026-02-08T19:57:02.062659Z\",\"close_reason\":\"Superseded by canonical FTUI bead graph under coding_agent_session_search-2dccg (Tracks A-K) with preserved scope and stronger dependency/test/logging coverage.\",\"source_repo\":\".\",\"compaction_level\":0,\"original_size\":0,\"dependencies\":[{\"issue_id\":\"coding_agent_session_search-2sp58\",\"depends_on_id\":\"coding_agent_session_search-2dccg.2\",\"type\":\"blocks\",\"created_at\":\"2026-02-11T06:20:54Z\",\"created_by\":\"import\",\"metadata\":\"{}\",\"thread_id\":\"\"}],\"comments\":[{\"id\":338,\"issue_id\":\"coding_agent_session_search-2sp58\",\"author\":\"Dicklesworthstone\",\"text\":\"Code verified: STYLE_KBD_KEY/DESC now wired into footer key hints at app.rs:11938-11939 (replacing STYLE_STATUS_INFO/TEXT_MUTED). accent fg for keys, text_subtle fg for descriptions.\",\"created_at\":\"2026-02-08T20:22:03Z\"}]}\n{\"id\":\"coding_agent_session_search-2t2d\",\"title\":\"Task: Cass reranker stage (CPU-only)\",\"description\":\"## Task\\nAdd an optional reranking step to cass search results using the **CPU-only reranker winner**.\\n\\n## Blocked On\\n- xf reranker winner (bd-5fj3)\\n\\n## Implementation Outline\\n1.

Each message has a role-colored bold header line, but no left-border/gutter.\\n- Results pane: The a11y-only gutter (app.rs:4208-4216) renders ONLY STYLE_ROLE_GUTTER_ASSISTANT and only when `styles.options.a11y == true`.\\n\\n## Where\\n\\n### Detail Pane (PRIMARY target):\\n- **app.rs:~4324-4379** — `build_messages_lines()` method\\n- Currently each message renders as:\\n  ```\\n  ✓ Agent (author) 14:23:45\\n  Content text here...\\n  ```\\n- Target: add a 2-char wide colored gutter on the LEFT of each message block:\\n  ```\\n  ┃ ✓ Agent (author) 14:23:45\\n  ┃ Content text here...\\n  ┃\\n  ```\\n  Where `┃` color comes from STYLE_ROLE_GUTTER_{USER,ASSISTANT,TOOL,SYSTEM}.\\n\\n### Results Pane (SECONDARY target):\\n- **app.rs:4208-4216** — Current code only renders assistant gutter in a11y mode\\n- Expand to: always render a 1-char role-indicator column in the results pane (not gutter, just a colored dot/line)\\n- Actually: the results pane shows SEARCH HITS, not messages. A hit does not have a \\\"role.\\\" Skip this — role gutters only make sense in the detail pane where actual messages with roles are displayed.\\n\\n**REVISED SCOPE**: Detail pane only. The results pane a11y gutter is fine as-is.\\n\\n## Implementation\\n\\nIn `build_messages_lines()`, wrap each message's lines with a gutter prefix:\\n\\n```rust\\nfor msg in &cv.messages {\\n    let role_s = Self::role_style(&msg.role, styles);\\n    let gutter_s = match msg.role {\\n        MessageRole::User => styles.style(STYLE_ROLE_GUTTER_USER),\\n        MessageRole::Agent => styles.style(STYLE_ROLE_GUTTER_ASSISTANT),\\n        MessageRole::Tool => styles.style(STYLE_ROLE_GUTTER_TOOL),\\n        MessageRole::System => styles.style(STYLE_ROLE_GUTTER_SYSTEM),\\n        MessageRole::Other(_) => styles.style(STYLE_TEXT_MUTED),\\n    };\\n    \\n    // Header line with gutter\\n    lines.push(Line::from_spans(vec![\\n        Span::styled(\\\"\\\\u{2503} \\\", gutter_s),  // ┃ (thick vertical bar)\\n        Span::styled(format!(\\\"{role_label}{author_suffix}{ts_label}\\\"), role_s.bold()),\\n    ]));\\n    \\n    // Content lines with gutter\\n    for content_line in rendered_content {\\n        lines.push(Line::from_spans(vec![\\n            Span::styled(\\\"\\\\u{2503} \\\", gutter_s),\\n            // ... existing content span\\n        ]));\\n    }\\n}\\n```\\n\\n## Style Token Definitions (style_system.rs:1017-1045)\\n```rust\\nSTYLE_ROLE_GUTTER_USER:      fg=user_color, bg=blend(bg, user_color, 0.18)\\nSTYLE_ROLE_GUTTER_ASSISTANT: fg=assistant_color, bg=blend(bg, assistant_color, 0.18)\\nSTYLE_ROLE_GUTTER_TOOL:      fg=tool_color, bg=blend(bg, tool_color, 0.18)\\nSTYLE_ROLE_GUTTER_SYSTEM:    fg=system_color, bg=blend(bg, system_color, 0.18)\\n```\\n\\n## Gutter Character Choice\\n- `┃` (U+2503, BOX DRAWINGS HEAVY VERTICAL) — thick, visible\\n- `│` (U+2502, BOX DRAWINGS LIGHT VERTICAL) — thinner, subtler\\n- Recommended: `┃` for the header line, `│` for content lines (visual hierarchy)\\n\\n## Required Tests\\n\\n### Unit tests:\\n1. `test_detail_messages_have_role_gutters` — Build message lines for a conversation with User + Agent + Tool messages. Verify each line starts with a gutter Span using the correct STYLE_ROLE_GUTTER_* token for that message's role.\\n2. `test_gutter_user_style` — Verify STYLE_ROLE_GUTTER_USER has both fg AND bg set (not just fg).\\n3. `test_gutter_all_roles_distinct` — For each preset, verify all 4 gutter styles have visually distinct colors (fg differs between all 4).\\n4. `test_gutter_markdown_messages` — Verify that markdown-rendered message content also gets gutter prefixed (the markdown renderer outputs multiple Lines; each needs a gutter).\\n5. `test_gutter_width_budget` — Verify the gutter consumes exactly 2 chars of width (1 bar + 1 space), leaving the rest for content.\\n\\n### Snapshot test:\\n6. Add `cassapp_detail_messages_gutters.snap` — Detail pane with 3+ messages showing colored gutters\\n\\n### E2E validation:\\n7. Add a test that renders a full conversation in the detail pane at width=80 and verifies no line exceeds the available width (gutter + content fit within inner rect).\\n\\n## Considerations\\n- The gutter MUST NOT break markdown rendering. The MarkdownRenderer returns `Vec<Line>`. Each Line needs a gutter Span prepended. If the Line already has Spans, insert at index 0.\\n- Width: the gutter consumes 2 chars. On Narrow breakpoint (<80 cols), the detail pane is already squeezed. Consider making gutters conditional on breakpoint >= MediumNarrow.\\n- The gutter should be visible in NORMAL mode (not just a11y). The old ratatui version had always-on role colors. a11y mode should add text markers ON TOP.\\n- Degradation: at NoStyling+, gutter color drops to plain (but the `┃` character remains for structure).\\n\\n## Acceptance\\n- All 4 role gutter styles used in detail pane rendering\\n- Each message has a colored left gutter matching its role\\n- Gutter visible in normal mode (not just a11y)\\n- Markdown content lines get gutter prefixed without layout overflow\\n- 5 unit tests + 1 snapshot test + 1 e2e test pass\\n- No clippy warnings\",\"status\":\"closed\",\"priority\":1,\"issue_type\":\"task\",\"created_at\":\"2026-02-08T19:31:34.635297Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-02-08T20:26:02.610794Z\",\"closed_at\":\"2026-02-08T19:57:02.068072Z\",\"close_reason\":\"Superseded by canonical FTUI bead graph under coding_agent_session_search-2dccg (Tracks A-K) with preserved scope and stronger dependency/test/logging coverage.\",\"source_repo\":\".\",\"compaction_level\":0,\"original_size\":0,\"dependencies\":[{\"issue_id\":\"coding_agent_session_search-2wcwq\",\"depends_on_id\":\"coding_agent_session_search-2dccg.2\",\"type\":\"blocks\",\"created_at\":\"2026-02-11T06:20:54Z\",\"created_by\":\"import\",\"metadata\":\"{}\",\"thread_id\":\"\"}],\"comments\":[{\"id\":339,\"issue_id\":\"coding_agent_session_search-2wcwq\",\"author\":\"Dicklesworthstone\",\"text\":\"Code verified: role_gutter_style() added for all 4 roles + Other.

Implementation options:\\n   - **Option A (compile-time)**: Have each STYLE_* constant be a `&str`. The test collects all of them into a Vec, then for each, checks a `USED_STYLES` set that rendering code populates. This requires instrumentation.\\n   - **Option B (source-level)**: The test reads `src/ui/app.rs` as a string (using `include_str\\\\!` or `fs::read_to_string`) and checks that each token name appears. Simple, effective, catches regressions.\\n   - **Recommended: Option B** — straightforward, no runtime overhead, catches dead tokens at `cargo test` time.\\n\\n```rust\\n#[test]\\nfn test_no_dead_style_tokens() {\\n    let app_source = include_str\\\\!(\\\"app.rs\\\");\\n    let tokens = [\\n        \\\"STYLE_APP_ROOT\\\", \\\"STYLE_PANE_BASE\\\", \\\"STYLE_PANE_FOCUSED\\\",\\n        \\\"STYLE_TEXT_PRIMARY\\\", \\\"STYLE_TEXT_MUTED\\\", \\\"STYLE_TEXT_SUBTLE\\\",\\n        // ... all 28+ tokens\\n    ];\\n    let mut dead = Vec::new();\\n    for token in &tokens {\\n        if \\\\!app_source.contains(token) {\\n            dead.push(*token);\\n        }\\n    }\\n    assert\\\\!(dead.is_empty(), \\\"Dead style tokens found: {:?}\\\", dead);\\n}\\n```\\n\\n2. `test_style_token_count_matches_definitions` — Count STYLE_* constants in style_system.rs, compare to the test's known list. Fails if someone adds a new token without updating the test.\\n\\n## Considerations\\n- If a token is used ONLY via a helper function in style_system.rs (like `score_style()` calls `STYLE_SCORE_HIGH`), the grep on app.rs might not find it.

This means we do not yet have full unit/integration coverage without mocks.\\n\\n## Scope\\n- Audit remaining mocks/fakes and categorize by subsystem.\\n- Define a strict no-mock policy with an explicit allowlist for unavoidable OS/hardware boundaries.\\n- Replace mocks/fakes with real components or real fixture data.\\n- Unify E2E logging across Rust tests, shell scripts, and Playwright.\\n- Provide a single orchestration entrypoint with JSONL + Markdown reports.\\n\\n## Non-Goals\\n- Adding new features to cass unrelated to testing.\\n- Rewriting existing test frameworks that already use real components.\\n\\n## Required Outcomes\\n1.

These features are only useful if tests prove the safety claims.\\n\\nProblem: each feature bead includes local tests, but the borrowed sibling-doctor capabilities interact. A repeated-repair refusal should appear in baseline diffs, failure contexts, support bundles, robot schemas, human output, and safe auto-run behavior. A post-repair probe failure should block promotion, write a marker, preserve forensic artifacts, and generate a reproducible fixture. Testing only each piece in isolation would miss the actual user workflows.\\n\\nScope: create an integration verification suite that exercises the combined safety features on deterministic fixtures. Required scenarios: healthy no-op, read-only derived-index corruption, archive DB corruption with intact mirror, pruned upstream source logs with intact cass mirror, candidate coverage shrink refusal, repeated repair after verification failure, post-repair write/read probe failure, lock contention with safe wait guidance, baseline save/diff after a derived-only failure, support bundle generation from a failed repair, archive exclusion warning, and safe auto-run skipping a risky repair.\\n\\nAcceptance criteria: each scenario emits structured logs, doctor JSON, human output snapshot where appropriate, operation receipt or no-mutation receipt, failure_context on failure, and artifact manifest. Tests assert no raw fixture session content appears in redacted logs or support bundles by default. Tests assert no live user cass data dir is touched. Goldens are reviewed and stable. The suite has enough logging that a future agent can diagnose a failure from artifacts alone.\\n\\nImplementation note: this bead should run after the individual feature beads and before release migration.

The daemon server intentionally creates a public symlink at the configured socket path when the parent directory is not owner-only: src/daemon/core.rs:104-122, and its cleanup helper removes stale sockets OR symlinks at that daemon path. The new client-side remove_stale_daemon_socket in src/daemon/client.rs:624-640 only removes file_type().is_socket(); any stale symlink is treated as a non-socket path and spawn_daemon returns DaemonError::Unavailable before starting a replacement daemon. Repro shape: use a socket path in a non-owner-only parent so bind_owner_only_unix_listener publishes socket_path -> private runtime daemon.sock, crash/kill the daemon so the symlink remains, then a client auto-spawn attempts cleanup and fails with 'refusing to remove non-socket daemon path'. Impact: daemon recovery is broken for cass-created public socket symlinks after crash/stale runtime cleanup, even though removing the symlink itself does not delete the target. Suggested fix: mirror server-side daemon artifact semantics in client cleanup: allow metadata.file_type().is_symlink() at the configured socket path, preserve regular files/dirs/FIFOs, and add a regression test for stale symlink preservation/removal behavior.\",\"status\":\"closed\",\"priority\":2,\"issue_type\":\"bug\",\"created_at\":\"2026-04-24T18:09:46.071997717Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-04-24T19:35:53.313118986Z\",\"closed_at\":\"2026-04-24T19:35:53.312710381Z\",\"close_reason\":\"Duplicate of vxycf, already fixed by commit f53df827 'fix(daemon): clean stale public socket symlinks' (same review finding from 4f70202b).

The errors were in the sibling repo at ../frankensqlite/crates/fsqlite, not in cass code. Because cass uses path dependencies, a broken frankensqlite = a broken cass.

Connection factory must return new FrankenStorage per producer thread\\n   - Alternative: refactor insert_conversations_batched to take &Connection directly\\n\\n2. Memory scaling concern:\\n   - Current PRAGMAs set mmap_size=256MB per connection\\n   - 15 producer connections x 256MB = 3.84GB mmap overhead\\n   - DECISION NEEDED: reduce per-connection mmap_size for writer connections (they don't need read perf), or use frankensqlite's native memory model which may not use mmap at all\\n\\n3. FTS5 batch optimization must be preserved:\\n   - Current code disables FTS triggers before batch insert, rebuilds after\\n   - With concurrent writers, FTS rebuild coordination is needed\\n   - Options: (a) each writer rebuilds its own FTS entries, (b) single post-batch FTS rebuild, (c) frankensqlite FTS5 may handle this differently\\n   - Must verify frankensqlite FTS5 concurrent write behavior\\n\\n4. Tantivy index coordination:\\n   - Indexer also builds tantivy full-text index alongside SQLite\\n   - Tantivy IndexWriter is NOT thread-safe for concurrent add_document()\\n   - Options: (a) keep tantivy writes serialized via channel/mutex, (b) use per-thread IndexWriter (not recommended), (c) migrate tantivy to frankensearch-lexical management\\n   - RECOMMENDATION: Keep tantivy writes on a single thread (the existing consumer pattern) even if SQLite writes go parallel. The tantivy bottleneck is much smaller than the SQLite bottleneck.\\n\\nNEW ARCHITECTURE WITH CONCURRENT WRITERS:\\n1. connection_factory(db_path, pragmas) -> FrankenStorage  \\n   - Returns a new FrankenStorage with PRAGMAs applied\\n   - Writer connections get reduced mmap_size (or none if frankensqlite doesn't use mmap)\\n2. Each connector producer thread: let storage = factory() -> storage.insert_conversations_batched() inside BEGIN CONCURRENT\\n3. Tantivy indexing stays serialized: producers send indexed-tantivy-docs via crossbeam channel to a single tantivy writer thread\\n4. frankensqlite SSI handles SQLite conflict detection (page-level conflicts)\\n5.

The effect is SUBTLE — a 50% blend between surface and background, not a jarring color change.\\n\\n## New Style Token (Optional)\\nConsider defining `STYLE_INPUT_BG` in style_system.rs:\\n```rust\\npub const STYLE_INPUT_BG: &str = \\\"input.bg\\\";\\nsheet.define(STYLE_INPUT_BG, Style::new()\\n    .bg(to_packed(blend(resolved.surface, resolved.background, 0.5))));\\n```\\nThis would make the input field background theme-aware and customizable.\\n\\n## Required Tests\\n\\n### Unit tests:\\n1. `test_search_input_has_background` — Render the search bar, verify the query row has a non-default background style applied (bg is Some).\\n2. `test_search_input_bg_differs_from_pane` — Verify the input bg color differs from STYLE_PANE_BASE bg.\\n3. `test_search_input_placeholder_visible` — With empty query, verify placeholder text (\\\"<type to search>\\\") is visible against the input background (contrast check).\\n4. `test_search_input_degradation` — At NoStyling, verify input bg drops to plain.\\n\\n### Snapshot test:\\n5. Update `cassapp_results_wide.snap` to show the input area with visible background distinction.\\n\\n## Considerations\\n- The blend ratio (0.5) may need tuning.

It should consume fixture scenario manifests, enforce each scenario no-mutation/mutation contract, support labels such as quick, slow, fault, cross-platform, privacy, and release, and preserve artifacts on failure. It must never launch the bare cass TUI.\\n\\nAcceptance criteria: e2e scripts can be run locally without touching real user ~/.codex, ~/.claude, or cass data dirs; each scenario produces manifest.json, scenario.json, commands.jsonl, stdout/stderr logs, parsed-json snapshots, file-tree-before/after, checksum summaries, timing summaries, receipt/event-log copies, and a concise failure summary; logs redact sensitive paths where required; CI can upload artifacts; the runner refuses to operate outside its temp root. Unit/smoke tests cover CLI parsing, label filtering, unsafe path refusal, JSON parsing failures, artifact manifest validation, and no-mutation assertions. E2E self-tests intentionally fail a scenario and verify failure_context plus artifacts are sufficient for diagnosis.\",\"status\":\"closed\",\"priority\":0,\"issue_type\":\"test\",\"created_at\":\"2026-05-04T23:12:05.925806264Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-05-05T04:50:00.755206130Z\",\"closed_at\":\"2026-05-05T04:50:00.754920465Z\",\"close_reason\":\"Implemented scripted doctor v2 e2e runner with isolated persistent run roots, scenario manifests, command JSONL, redacted stdout/stderr, parsed JSON snapshots, before/after file trees, checksum/timing/receipt/event artifacts, no-mutation enforcement, failure_context summaries, a shell entry point, and smoke/unit tests.

Those tests only become practical if future agents have one deterministic fixture factory and scenario-manifest format instead of inventing one-off temp directories for every bead. Without a shared factory, tests will drift, miss important archive states, or accidentally point at live user cass data.\\n\\nScope: build a reusable doctor fixture factory and scenario manifest layer for tests and developer tooling. It should create isolated cass data dirs for healthy archives, source-pruned archives, raw-mirror-present/absent states, DB-corrupt states, derived-index-corrupt states, backup-available states, stale/active locks, interrupted repair markers, privacy-sensitive sessions, multi-machine/source-sync gaps, disk-pressure simulations where safe, and platform/path edge cases. Each scenario manifest must declare fixture id, risk class, expected mutation class, allowed commands, forbidden live paths, expected artifacts, expected redaction policy, expected repair eligibility, and exact cleanup responsibilities for temp test data.\\n\\nAcceptance criteria: no scenario can target the users live cass data dir by default; every fixture is deterministic enough for golden tests; generated source logs, raw mirror blobs, DB rows, config, bookmarks, backups, receipts, event logs, and sidecars are internally consistent; scenario manifests validate before any test command runs; stdout/stderr/log/artifact paths are captured; fixture seeds include realistic sensitive strings so privacy tests can prove redaction; test logs include scenario id, fixture root, data-dir inventory, DB row counts, mirror hash inventory, expected anomaly classes, command argv, exit code, parsed JSON path, receipt path, failure_context path, and final before/after inventory. Unit tests cover manifest validation, live-path refusal, deterministic fixture generation, sensitive-seed redaction, corrupt/partial fixture generation, and cleanup-scope enforcement. E2E smoke tests use the factory to run at least one read-only check, one blocked archive-risk repair, one derived-only repair, and one reconstruction-after-pruning scenario with detailed artifacts.\\n\\nImplementation note: this bead is test infrastructure, not production repair logic. It exists so the rest of doctor v2 can prove safety claims cheaply and repeatably. It must never delete or rewrite real user archives, and it must never require bare cass TUI commands.\",\"status\":\"closed\",\"priority\":0,\"issue_type\":\"task\",\"created_at\":\"2026-05-05T10:32:59.660505669Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-05-05T10:51:51.670411325Z\",\"closed_at\":\"2026-05-05T10:51:51.670132684Z\",\"close_reason\":\"Implemented deterministic doctor fixture scenario manifests and e2e fixture inventory artifacts with focused tests, full Rust gates, and clean bead graph validation.\",\"source_repo\":\".\",\"compaction_level\":0,\"original_size\":0,\"labels\":[\"cass-doctor-v2\",\"developer-tooling\",\"e2e\",\"fixtures\",\"goldens\",\"safety\",\"testing\"],\"dependencies\":[{\"issue_id\":\"coding_agent_session_search-4g3c8\",\"depends_on_id\":\"coding_agent_session_search-l7g5r\",\"type\":\"blocks\",\"created_at\":\"2026-05-05T10:32:59.660505669Z\",\"created_by\":\"ubuntu\",\"metadata\":\"{}\",\"thread_id\":\"\"},{\"issue_id\":\"coding_agent_session_search-4g3c8\",\"depends_on_id\":\"coding_agent_session_search-ucx3y\",\"type\":\"blocks\",\"created_at\":\"2026-05-05T10:32:59.660505669Z\",\"created_by\":\"ubuntu\",\"metadata\":\"{}\",\"thread_id\":\"\"},{\"issue_id\":\"coding_agent_session_search-4g3c8\",\"depends_on_id\":\"coding_agent_session_search-vvuy8.1\",\"type\":\"blocks\",\"created_at\":\"2026-05-05T10:32:59.660505669Z\",\"created_by\":\"ubuntu\",\"metadata\":\"{}\",\"thread_id\":\"\"}],\"comments\":[{\"id\":921,\"issue_id\":\"coding_agent_session_search-4g3c8\",\"author\":\"ubuntu\",\"text\":\"Implemented deterministic doctor fixture contract hardening and e2e artifact inventory support.

T1 can commit more frames between those copies, so the backup bundle can contain mismatched main/WAL/SHM state. Rust ownership does not prevent this: the writer can be another process, and create_backup only has a Path plus its own read-only connection, not a database-wide mutex.

doctor v2 migration, performance, and concurrent operation behavior\",\"description\":\"Background: doctor is a tool people run when things are already stressful. It must not be surprisingly slow, must migrate existing data dirs safely, and must behave under concurrent index/search activity. This bead is the practical release gate that proves the new safety machinery does not make normal health checks unpleasant.\\n\\nScope: test old data dirs with no raw mirror, large archives, active search readers, active index rebuild locks, disk-pressure scenarios, remote/source configs, compatibility aliases, and partially migrated doctor state. Measure check latency, status latency, baseline diff time, source coverage scan time, and repair planning time. Ensure health remains fast even after adding coverage fields and that heavier scans produce truthful recommended_action guidance rather than blocking quick readiness.\\n\\nAcceptance criteria: migration from existing cass DBs is additive; check remains bounded; repair planning avoids heavy rebuild unless asked; concurrent readers see old or new state, never partial state.

Cass doctor v2 already has a concurrency and interrupted-repair state model plus an operation event log, but the plan should require user-facing metrics that explain why doctor is slow or blocked.\\n\\nProblem: users will run doctor while indexing, search rebuilds, source sync, model install, or another doctor process may be active. A plain lock-busy error is not enough. Doctor should say which lock is involved, who appears to hold it, how old it is, whether it is safe to wait, and which phases are taking unusual time, while avoiding unsafe advice like deleting lock files manually when stale ownership is uncertain.\\n\\nScope: add structured lock and timing diagnostics to doctor check, health/status integration, and mutating repair receipts. Capture advisory lock path, lock kind, owner pid when available, owner command if safe to report, age, last heartbeat, stale suspicion, wait duration, retry policy, slow phase name, phase duration, threshold, and recommended action. Include metrics for archive DB open, quick_check/integrity-style checks, raw mirror scan, source ledger scan, lexical probe, semantic probe, backup verify, candidate build, post-repair probe, support-bundle generation, baseline diff, and atomic promotion. Metrics should be redacted and bounded so health/status do not become slow.\\n\\nAcceptance criteria: robot output includes locks[], slow_operations[], timing_summary, and retry_recommendation. Human output distinguishes active healthy work from stale-looking locks without telling users to delete lock files manually. Unit tests cover active lock, stale marker, missing pid, pid reuse ambiguity, permission denied reading pid metadata, slow phase threshold, metric redaction, and no-lock healthy output. E2E tests include concurrent doctor/read-only and doctor/fix lock scenarios with detailed logs, event-log correlation, and recommendations that are safe and specific.\\n\\nImplementation note: this bead should avoid false certainty.

Aim for WCAG 2.1 Level AA compliance.\\n\\n## Background & Rationale\\n\\n### Why Accessibility Matters\\n1. **Inclusion**: Everyone should be able to access their archived conversations\\n2. **Legal**: Many jurisdictions require accessible web content\\n3. **Usability**: Accessibility features often improve usability for everyone\\n4. **Quality**: Accessible code is often better-structured code\\n\\n### Target Standards\\n- WCAG 2.1 Level AA (Web Content Accessibility Guidelines)\\n- Section 508 (US federal accessibility standard)\\n- EN 301 549 (European accessibility standard)\\n\\n## Accessibility Requirements\\n\\n### 1. Keyboard Navigation\\n\\nAll functionality must be accessible via keyboard:\\n\\n```html\\n<!-- All interactive elements must be focusable -->\\n<button id=\\\"unlock-button\\\" tabindex=\\\"0\\\">Unlock</button>\\n\\n<!-- Skip links for screen readers -->\\n<a href=\\\"#main-content\\\" class=\\\"skip-link\\\">Skip to main content</a>\\n\\n<!-- Logical tab order -->\\n<form id=\\\"password-form\\\">\\n  <input id=\\\"password-input\\\" type=\\\"password\\\" tabindex=\\\"1\\\">\\n  <button id=\\\"unlock-button\\\" tabindex=\\\"2\\\">Unlock</button>\\n  <button id=\\\"qr-button\\\" tabindex=\\\"3\\\">Scan QR</button>\\n</form>\\n```\\n\\n**Keyboard Shortcuts:**\\n```javascript\\ndocument.addEventListener(\\\"keydown\\\", (e) => {\\n    if (e.key === \\\"Escape\\\") {\\n        closeModal();\\n    }\\n    if (e.key === \\\"/\\\" && !isInInput()) {\\n        focusSearchInput();\\n        e.preventDefault();\\n    }\\n    if (e.key === \\\"Enter\\\" && e.target.classList.contains(\\\"search-result\\\")) {\\n        openConversation(e.target.dataset.id);\\n    }\\n});\\n```\\n\\n### 2. Screen Reader Support\\n\\n#### ARIA Labels\\n\\n```html\\n<!-- Regions -->\\n<main role=\\\"main\\\" aria-label=\\\"Search and browse conversations\\\">\\n<nav role=\\\"navigation\\\" aria-label=\\\"Result navigation\\\">\\n<aside role=\\\"complementary\\\" aria-label=\\\"Conversation details\\\">\\n\\n<!-- Dynamic content -->\\n<div aria-live=\\\"polite\\\" aria-atomic=\\\"true\\\" id=\\\"status\\\">\\n  <span class=\\\"sr-only\\\">Search results updated</span>\\n</div>\\n\\n<!-- Password field -->\\n<label for=\\\"password-input\\\" id=\\\"password-label\\\">\\n  Enter your password to unlock the archive\\n</label>\\n<input \\n  id=\\\"password-input\\\" \\n  type=\\\"password\\\"\\n  aria-labelledby=\\\"password-label\\\"\\n  aria-describedby=\\\"password-hint\\\"\\n>\\n<span id=\\\"password-hint\\\" class=\\\"sr-only\\\">\\n  The password was set when this archive was created\\n</span>\\n\\n<!-- Search results -->\\n<ul role=\\\"listbox\\\" aria-label=\\\"Search results\\\">\\n  <li role=\\\"option\\\" aria-selected=\\\"false\\\" tabindex=\\\"0\\\">\\n    <span class=\\\"result-title\\\">Conversation Title</span>\\n    <span class=\\\"result-meta\\\" aria-label=\\\"From Claude Code, January 5 2025\\\">\\n      Claude Code • Jan 5\\n    </span>\\n  </li>\\n</ul>\\n```\\n\\n#### Live Regions\\n\\n```javascript\\n// Announce search results\\nfunction announceResults(count) {\\n    const status = document.getElementById(\\\"status\\\");\\n    status.textContent = `Found ${count} ${count === 1 ? \\\"result\\\" : \\\"results\\\"}`;\\n}\\n\\n// Announce errors\\nfunction announceError(message) {\\n    const error = document.getElementById(\\\"error-announcer\\\");\\n    error.setAttribute(\\\"role\\\", \\\"alert\\\");\\n    error.textContent = message;\\n}\\n```\\n\\n### 3.

Broader scan shows the pattern is systemic:\\n\\n- `assert!(X.is_some())` with no follow-up unwrap+equality check: at least 13 distinct test files carry this pattern, spread across connector_*.rs (amp, claude, codex, copilot_cli, gemini, opencode), storage*.rs, pages_wizard.rs, secret_scan.rs, search_asset_harness.rs.\\n- `assert!(!X.is_empty())` with no count or content pin: at least 15 test files.\\n- `assert!(X.contains(\\\"single_token\\\"))` without checking the enclosing line structure: at least 10 test files.\\n\\nThese assertions look like they pass when the code under test is correct but ALSO pass when a regression has quietly degraded the output shape — a fresh`None` that used to be `Some(expected)`, a scanned batch that dropped to a single result, an event string that no longer includes the accompanying fields.\\n\\nEXAMPLES of the upgrade pattern already shipped as reference:\\n- 0336ca4b: `assert!(mode.is_some())` → `assert_eq!(mode, Some(SearchMode::Semantic), \\\"...\\\")`\\n- 6227d21d: two independent `out.contains(...)` probes → find single line + assert both fields on THAT line\\n- e191d9f1: `!manifest.files.is_empty()` → `>= 15 AND contains(specific_asset_name)` with diagnostic\\n- b1a99590: `metadata.len() > 0` → `>= 1024 bytes` with named floor\\n\\nPROPOSED APPROACH:\\n1. Batch-review each of the three pattern categories across the identified test files, one per commit.\\n2. For `.is_some()` on enum-typed Options: always pin the expected variant via `assert_eq!(x, Some(Variant))`.\\n3. For `!is_empty()`: pin a concrete lower bound (`>= N`) AND at least one expected element by name/content.\\n4. For `contains(single_token)`: if two or more `.contains()` probes are expected to come from the same event, rewrite to find the event line first and assert all fields on that line.\\n5. Keep diagnostics specific (\\\"got {N} entries: {:?}\\\") so failure mode is immediately actionable.\\n\\nEstimated cost: ~15 test files x 20 min/file (identify candidates, upgrade, verify) = 5 hours of careful work spread across multiple panes.

A pre-publish summary prevents \\\"I didnt realize that was in there\\\" regrets.\\n3. **Confirmation Gates**: Irreversible actions (publishing to GitHub Pages) require explicit confirmation with clear warnings.\\n4. **Documentation**: Users need to understand the security model, trust assumptions, and operational procedures.\\n\\n## Components\\n\\n### 5.1 Secret Detection Engine\\nScan all exported content for potential secrets before encryption:\\n- API keys (AWS, OpenAI, Anthropic, GitHub, etc.)\\n- Passwords and tokens in various formats\\n- Private keys (SSH, PGP, certificates)\\n- Connection strings with embedded credentials\\n- Environment variable patterns\\n\\n### 5.2 Pre-Publish Summary\\nGenerate comprehensive summary showing:\\n- Total conversations and messages being exported\\n- Date range of content\\n- Workspaces/projects included\\n- Detected secrets (with redacted previews)\\n- Estimated archive size\\n- Key slot configuration\\n\\n### 5.3 Safety Confirmations\\nMulti-step confirmation for irreversible actions:\\n- Display warnings about public publishing\\n- Require explicit \\\"I understand\\\" acknowledgments\\n- Option to abort at any stage\\n- Clear indication of what will be published where\\n\\n### 5.4 Documentation Generation\\nAuto-generate deployment-specific docs:\\n- README for the generated site\\n- Security model explanation\\n- Recovery procedures\\n- Troubleshooting guide\\n\\n## Dependencies\\n- Depends on: Phase 4 (need complete wizard to integrate safety checks)\\n- Blocks: Phase 6 (testing validates safety features)\\n\\n## Exit Criteria\\n- [ ] Secret detection catches 95%+ of common secret patterns\\n- [ ] Pre-publish summary accurately reflects export contents\\n- [ ] Confirmation flow prevents accidental publishing\\n- [ ] Generated documentation is complete and accurate\\n- [ ] All safety features tested with synthetic secrets\",\"status\":\"closed\",\"priority\":2,\"issue_type\":\"feature\",\"created_at\":\"2026-01-07T01:39:46.253684Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-01-27T02:38:14.376681Z\",\"closed_at\":\"2026-01-27T02:38:14.376600Z\",\"close_reason\":\"All Phase 5 subtasks completed: P5.1 Secret Detection, P5.1a Redaction System, P5.2 Pre-Publish Summary, P5.3 Safety Confirmations, P5.4 Documentation, P5.5 Unencrypted Export Warning, P5.6 Share Profiles - all closed.\",\"source_repo\":\".\",\"compaction_level\":0,\"original_size\":0,\"dependencies\":[{\"issue_id\":\"coding_agent_session_search-7s76\",\"depends_on_id\":\"coding_agent_session_search-w3o7\",\"type\":\"blocks\",\"created_at\":\"2026-02-11T06:20:53Z\",\"created_by\":\"import\",\"metadata\":\"{}\",\"thread_id\":\"\"}]}\n{\"id\":\"coding_agent_session_search-7tsm\",\"title\":\"Hash embedder (FNV-1a feature hashing)\",\"description\":\"## Purpose\\nImplement FNV-1a feature hashing embedder as deterministic fallback.\\n\\n## Background\\nHash embeddings are not 'true' semantic (keyword overlap with random projection) but provide:\\n- Instant embedding (no model loading)\\n- Deterministic output (reproducible)\\n- Zero network dependency\\nUsed when: (a) ML model not installed, (b) user opts for hash mode via CASS_SEMANTIC_EMBEDDER=hash\\n\\n## Key Implementation\\n- FNV-1a hash for tokens with dimension projection\\n- Tokenization: lowercase, split non-alphanumeric, filter len >= 2\\n- L2 normalization required for cosine similarity\\n\\n## Acceptance Criteria\\n- [ ] HashEmbedder implements Embedder trait\\n- [ ] Deterministic: same input → same output\\n- [ ] Output is L2 normalized (norm ≈ 1.0)\\n- [ ] Dimension matches config (default 384)\\n\\n## Depends On\\n- sem.emb.trait (Embedder trait definition)\\n\\n## References\\n- Plan: Section 4.3 Hash Embedder\",\"status\":\"closed\",\"priority\":1,\"issue_type\":\"task\",\"created_at\":\"2025-12-19T01:22:53.585017Z\",\"updated_at\":\"2026-01-05T22:59:36.429157Z\",\"closed_at\":\"2026-01-05T16:04:19.602743Z\",\"source_repo\":\".\",\"compaction_level\":0,\"original_size\":0,\"dependencies\":[{\"issue_id\":\"coding_agent_session_search-7tsm\",\"depends_on_id\":\"coding_agent_session_search-vmet\",\"type\":\"blocks\",\"created_at\":\"2026-02-11T06:20:54Z\",\"created_by\":\"import\",\"metadata\":\"{}\",\"thread_id\":\"\"}]}\n{\"id\":\"coding_agent_session_search-7wm\",\"title\":\"DOC.4: Help Modal - Sources System Section\",\"description\":\"# Task: Add Sources System Section to Help Modal\\n\\n## Context\\nThe help modal (`?` or F1 key) is the primary in-app reference.

The non-staged rebuild_tantivy_from_db_with_options branch would need to also stage-then-swap, not mutate live in place.\\n- Either way, flip the test's legal-state set to {stable_count, None, Err} (drop the Some(0) carve-out) once the fix lands.\",\"status\":\"closed\",\"priority\":2,\"issue_type\":\"bug\",\"created_at\":\"2026-04-23T18:04:26.407387177Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-04-23T20:29:02.528066553Z\",\"closed_at\":\"2026-04-23T20:29:02.527712921Z\",\"close_reason\":\"route fresh single-shard rebuilds through staged atomic publish to eliminate the 0-doc reader window\",\"source_repo\":\".\",\"compaction_level\":0,\"original_size\":0,\"comments\":[{\"id\":737,\"issue_id\":\"coding_agent_session_search-9ct8r\",\"author\":\"cc_2\",\"text\":\"2026-04-23: scoped investigation surfaces that the minimal \\\"just skip the pre-wipe\\\" fix is NOT safe without a coordinated refactor of rebuild_tantivy_from_db_with_options.\\n\\nINVESTIGATION:\\n\\nThe 0-doc window comes from src/indexer/mod.rs:12322-12336:\\n\\n    if restart_from_zero {\\n        fs::remove_dir_all(&index_path)?;\\n        fs::create_dir_all(&index_path)?;\\n        rebuild_state = LexicalRebuildState::new(...);\\n    }\\n\\nThis runs BEFORE the delegation to rebuild_tantivy_from_db_via_staged_shards at line 12507. The staged-shards path DOES build into a TempDirBuilder tmpdir and calls publish_staged_lexical_index at the end, so removing the pre-wipe would let publish atomically replace the old live index instead of the empty post-wipe stub.\\n\\nHOWEVER, publish_staged_lexical_index does NOT carry forward the lexical-rebuild-state.json written earlier by persist_lexical_rebuild_state_for_active_run_start at line 11268 (inside rebuild_tantivy_from_db_via_staged_shards). That state is persisted to LIVE index_path, and when publish swaps the staged tmpdir in, the state file is moved with the OLD index into .lexical-publish-backups/. After publish the new index_path has NO state file, so the next cass run treats the (fully-rebuilt) index as restart_from_zero again.\\n\\nToday the pre-wipe masks this by guaranteeing a fresh state file gets created inside the pre-wiped dir, matching the tmpdir's assumed layout. Removing the pre-wipe without also migrating persist_lexical_rebuild_state_for_active_run_start to write into the staged tmpdir (or rewriting after publish against the NEW live path) would break resume semantics for subsequent runs.\\n\\nALSO: the non-staged fall-through path at line 12534-12565 opens a TantivyIndex writer directly on index_path — so scratch-dir redirect requires routing 25+ uses of index_path through a local shadow variable AND making publish_staged_lexical_index the only path that touches the live path.\\n\\nThis is a multi-hour refactor, not a 60-minute fix.\\n\\nPROPOSED FIX PLAN (for the next pane that picks this up):\\n\\n1. Introduce a scratch_index_path allocation right after index_dir(data_dir):\\n     let scratch_index_path = TempDirBuilder::new()\\n         .prefix(\\\"cass-lexical-rebuild-scratch.\\\")\\n         .tempdir_in(index_path.parent().unwrap_or(Path::new(\\\".\\\")))?;\\n2. Shadow index_path with scratch_index_path for the remainder of the function when restart_from_zero.\\n3. Remove the pre-wipe entirely — the scratch path is already empty.\\n4. Change the final publish (bottom of rebuild_tantivy_from_db_with_options AND rebuild_tantivy_from_db_via_staged_shards) to call publish_staged_lexical_index(&scratch_index_path, &original_index_path) before returning.\\n5. Also route persist_lexical_rebuild_state_for_active_run_start to write INTO the scratch dir so the state file survives the atomic swap.\\n6. Audit the 25 uses of &index_path inside rebuild_tantivy_from_db_with_options to ensure each targets scratch_index_path.\\n7. Audit the parallel rebuild_tantivy_from_db_via_staged_shards (which already uses a staging pattern) to ensure scratch_index_path composition is consistent.\\n8. Drop the Ok(Some(0)) carve-out in tests/atomic_swap_publish_crash_window.rs to enforce the stronger invariant.\\n9.

Observe: index_path has NEW content, staged_path still has OLD content,\\n#    .lexical-publish-backups/ is empty.\\n\\\\`\\\\`\\\\`\\n\\nProperty-test form: for every interleaving of the sequence [renameat2(A), rename-to-backup(B), sync-parent], if the process crashes after A but before the crash marker is durably recorded, subsequent startup either:\\n  (a) finds OLD content at a canonical recovery path, OR\\n  (b) moves OLD into .lexical-publish-backups/,\\nwithout user intervention. Current implementation fails (a) and (b).\\n\\n## Suggested fix\\nTwo approaches; (2) is the complete one.\\n\\n### 1. Record a crash marker BEFORE the swap (cheap, narrow)\\nBefore \\\\`atomic_exchange_paths\\\\`, write a small sidecar like \\\\`<data_dir>/.lexical-publish-swap-in-progress.json\\\\`:\\n\\n\\\\`\\\\`\\\\`json\\n{\\n  \\\\\\\"staged_path\\\\\\\": \\\\\\\"/.../cass-lexical-merge.xyz/final/index\\\\\\\",\\n  \\\\\\\"live_path\\\\\\\":   \\\\\\\"/.../index\\\\\\\",\\n  \\\\\\\"started_at\\\\\\\":  \\\\\\\"2026-04-23T12:34:56Z\\\\\\\"\\n}\\n\\\\`\\\\`\\\\`\\n\\nFsync it + parent. Delete the marker only AFTER step B completes + is fsynced.\\n\\nExtend \\\\`recover_or_finalize_interrupted_lexical_publish_backup\\\\` to also look for this marker. If found, verify \\\\`live_path\\\\` is a valid index (it should be — swap was atomic), then move \\\\`staged_path\\\\` content (now OLD after swap) into \\\\`.lexical-publish-backups/\\\\` with a recovered-dated suffix. Delete the marker.\\n\\nThis is the minimal fix that closes the window; the marker records the state well enough for recovery to act.\\n\\n### 2. Use \\\\`<index_path>/../.<name>.publish-pending-retain\\\\` rename as the marker\\nSkip a separate sidecar JSON. After \\\\`atomic_exchange_paths\\\\`, FIRST rename the staged-path (which now holds OLD) to a CANONICAL sibling like \\\\`<data_dir>/.<name>.publish-pending-retain\\\\`, THEN rename to the unique retained-backup path. The canonical sibling name is what \\\\`recover_or_finalize_...\\\\` already checks on non-Linux (\\\\`.<name>.publish-in-progress.bak\\\\`); reuse the same recovery path for the Linux post-swap orphan. No new JSON, just one extra rename step that gives recovery a fixed handle.\\n\\n## Test obligations for the fix\\nAdd a unit test (inside src/indexer/mod.rs::tests) that:\\n1. Populates a live index with OLD content (commit 1 doc).\\n2. Stages a new index with NEW content (commit 2 docs).\\n3. Manually invokes \\\\`atomic_exchange_paths(index_path, staged_index_path)\\\\` (simulating step A success).\\n4. Does NOT invoke the retain step (simulating crash).\\n5. Calls \\\\`recover_or_finalize_interrupted_lexical_publish_backup(&index_path)\\\\`.\\n6. Asserts:\\n   - live index at \\\\`index_path\\\\` reports 2 docs (NEW content preserved).\\n   - \\\\`.lexical-publish-backups/\\\\` contains exactly one entry with 1 doc (OLD content recovered).\\n   - No orphan directories sit at the prior \\\\`staged_index_path\\\\`.\\n\\nNote: writing this test cleanly on Linux requires calling \\\\`atomic_exchange_paths\\\\` directly (already a private fn; would need a #[cfg(test)] wrapper or test-module hook). Alternative is injecting a hook into \\\\`publish_staged_lexical_index\\\\` that optionally skips the retain step for tests.\\n\\n## Severity rationale\\nMEDIUM, not HIGH:\\n- Reader-correctness is preserved (atomic swap means no half-torn index).\\n- The data loss affects backups only; live index is always consistent.\\n- Probability of the crash window is low (one fs::rename between renameat2 and done).\\n- Contract violation is real and pinned by the existing regression test\\n  \\\\`publish_staged_lexical_index_retains_every_backup_unboundedly_today_pending_retention_cap\\\\`.\\n\\nLabels: indexer, lexical, atomic-swap, crash-safety, publish.\",\"status\":\"closed\",\"priority\":1,\"issue_type\":\"bug\",\"created_at\":\"2026-04-23T18:01:06.765390424Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-04-23T18:15:06.419013058Z\",\"closed_at\":\"2026-04-23T18:15:06.418739726Z\",\"close_reason\":\"Fixed in commit 67239d87: Linux atomic-swap publish path now parks OLD at the canonical .<name>.publish-in-progress.bak sidecar AFTER renameat2 succeeds and BEFORE moving it to .lexical-publish-backups/.

If cass is the only remaining archival copy after upstream harness pruning, users also need a safe way to move the archive ecosystem to a larger disk or produce a verified offline export without guessing which paths matter.\\n\\nProblem: guidance that says free space elsewhere or back up the archive still leaves users to invent manual copy recipes. Manual copies can omit WAL and SHM sidecars, raw mirror blobs, receipts, backup manifests, support bundles, bookmarks, sources.toml, or privacy metadata. Worse, a rushed user may delete the old archive after copying without verification. Doctor should provide an explicit, fingerprinted, additive workflow for relocation and verified export so storage pressure can be resolved without treating precious evidence as disposable cache.\\n\\nScope: add a doctor archive relocate and/or archive export workflow that plans all archive-critical path classes, estimates required space, copies to a target directory or export bundle, verifies byte counts and checksums, opens the relocated archive with frankensqlite, verifies raw mirror and backup manifests, runs read-only coverage probes, writes receipts and event logs, and only then offers an explicit follow-up to switch cass config to the new location. The old archive path must be retained as evidence and must not be deleted automatically. If config update is supported, it must be fingerprint-approved, backed up first, and rollbackable. Optional compression or encryption should follow the raw-mirror privacy policy and must be explicit.\\n\\nAcceptance criteria: robot output exposes relocation_plan_id, plan_fingerprint, source_roots, target_root, required_bytes, copied_bytes, verified_asset_classes, skipped_asset_classes, privacy_mode, config_update_status, old_archive_retained, receipts, event_log_path, and recommended_action. Human output explains that this is a preservation workflow, not cleanup, and never tells users to delete the old archive. Unit tests cover path traversal refusal, target-inside-source refusal, missing sidecars, checksum mismatch, insufficient target space, interrupted copy resume/reporting, config backup and rollback, compression/encryption metadata, and no-delete behavior. E2E tests create a storage-pressure fixture where precious evidence dominates, run relocation/export dry-run and apply against fixture data, verify before/after inventories and checksums, prove the relocated archive opens and search/doctor check can read it, and assert the old archive and source evidence remain byte-identical.\\n\\nImplementation note: this bead should depend on storage-pressure reporting, backup/restore verification, backup-exclusion diagnostics, raw-mirror privacy policy, forensic bundle capture, post-repair probes, and the audited filesystem mutation executor. It should feed release docs, golden schemas, comprehensive safety tests, and the operator UX epic so future users get a safe alternative before they reach for manual deletion.\",\"status\":\"open\",\"priority\":1,\"issue_type\":\"feature\",\"created_at\":\"2026-05-05T23:17:46.630473222Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-05-05T23:18:24.594560913Z\",\"source_repo\":\".\",\"compaction_level\":0,\"original_size\":0,\"labels\":[\"archive-preservation\",\"backup\",\"cass-doctor-v2\",\"e2e\",\"robot-json\",\"safety\",\"storage\",\"testing\"],\"dependencies\":[{\"issue_id\":\"coding_agent_session_search-ag0jo\",\"depends_on_id\":\"coding_agent_session_search-8y4wn\",\"type\":\"blocks\",\"created_at\":\"2026-05-05T23:17:58.564331718Z\",\"created_by\":\"ubuntu\",\"metadata\":\"{}\",\"thread_id\":\"\"},{\"issue_id\":\"coding_agent_session_search-ag0jo\",\"depends_on_id\":\"coding_agent_session_search-hghgl\",\"type\":\"blocks\",\"created_at\":\"2026-05-05T23:17:59.301599597Z\",\"created_by\":\"ubuntu\",\"metadata\":\"{}\",\"thread_id\":\"\"},{\"issue_id\":\"coding_agent_session_search-ag0jo\",\"depends_on_id\":\"coding_agent_session_search-l7g5r\",\"type\":\"blocks\",\"created_at\":\"2026-05-05T23:17:59.591731939Z\",\"created_by\":\"ubuntu\",\"metadata\":\"{}\",\"thread_id\":\"\"},{\"issue_id\":\"coding_agent_session_search-ag0jo\",\"depends_on_id\":\"coding_agent_session_search-r1a5e\",\"type\":\"blocks\",\"created_at\":\"2026-05-05T23:17:58.912569891Z\",\"created_by\":\"ubuntu\",\"metadata\":\"{}\",\"thread_id\":\"\"},{\"issue_id\":\"coding_agent_session_search-ag0jo\",\"depends_on_id\":\"coding_agent_session_search-t353q\",\"type\":\"blocks\",\"created_at\":\"2026-05-05T23:18:00.256674685Z\",\"created_by\":\"ubuntu\",\"metadata\":\"{}\",\"thread_id\":\"\"},{\"issue_id\":\"coding_agent_session_search-ag0jo\",\"depends_on_id\":\"coding_agent_session_search-v3puv\",\"type\":\"blocks\",\"created_at\":\"2026-05-05T23:17:59.916009585Z\",\"created_by\":\"ubuntu\",\"metadata\":\"{}\",\"thread_id\":\"\"},{\"issue_id\":\"coding_agent_session_search-ag0jo\",\"depends_on_id\":\"coding_agent_session_search-w5fem\",\"type\":\"blocks\",\"created_at\":\"2026-05-05T23:18:00.542804140Z\",\"created_by\":\"ubuntu\",\"metadata\":\"{}\",\"thread_id\":\"\"}],\"comments\":[{\"id\":1038,\"issue_id\":\"coding_agent_session_search-ag0jo\",\"author\":\"ubuntu\",\"text\":\"Audit rationale: this bead exists because low disk is a predictable point of user panic.

Approximately **50% of the 56ms** is F16→F32 conversion overhead.\\n\\n### Analysis Details\\n- 19.2 million F16→F32 conversions per query (50k vectors × 384 dimensions)\\n- Each conversion: ~1-2 CPU cycles for the conversion + memory access\\n- Conversions happen per-query, wasting cycles on identical work\\n\\n### Current Implementation (vector_index.rs:1221-1228)\\n```rust\\nfn dot_product_f16(a: &[f16], b: &[f32]) -> f32 {\\n    a.iter().zip(b.iter()).map(|(x, y)| f32::from(*x) * y).sum()\\n}\\n```\\n\\nThe `f32::from(*x)` call happens 384 times per vector, 50k times per query.\\n\\n## Proposed Solution\\n\\nConvert the entire F16 slab to F32 at `VectorIndex::load()` time, paying the conversion cost once instead of per-query.\\n\\n### Implementation Location\\n- File: `src/search/vector_index.rs`\\n- Function: `VectorIndex::load()` (around line 100-150)\\n- Modify `VectorStorage` enum handling\\n\\n### Code Sketch\\n```rust\\n// In VectorIndex::load()\\nlet vectors = match header.quantization {\\n    Quantization::F16 => {\\n        let f16_slice = bytes_as_f16(&mmap[slab_start..slab_end])?;\\n        let f32_slab: Vec<f32> = f16_slice.iter().map(|v| f32::from(*v)).collect();\\n        VectorStorage::F32(f32_slab)  // Store as F32 in memory\\n    }\\n    Quantization::F32 => { /* unchanged */ }\\n};\\n```\\n\\n## Isomorphism Proof\\n\\nThis optimization preserves search correctness because:\\n1. `f32::from(f16)` is **injective and deterministic** - same input always produces same output\\n2. The same conversion happens once at load vs once per-query - mathematically identical\\n3. Dot product inputs are identical → outputs are identical\\n4. No ranking or result set changes possible\\n\\n## Trade-offs\\n\\n### Costs\\n- **2x memory usage** for F16 indices: 76.8 MB vs 38.4 MB for 50k × 384 vectors\\n- **Loses mmap benefits**: Currently `VectorStorage::Mmap` enables lazy page loading and OS caching. Converting to heap-allocated `Vec<f32>` requires loading entire slab into memory at startup.\\n\\n### Mitigations\\n- Memory increase is acceptable for 20x speedup (76.8 MB is still small)\\n- For very large indices, consider keeping mmap with optional \\\"preload\\\" flag\\n- Most users have plenty of RAM for coding agent conversations\\n\\n## Expected Impact\\n\\n| Metric | Before | After |\\n|--------|--------|-------|\\n| `vector_index_search_50k` | 56ms | ~30ms |\\n| Memory (50k F16 vectors) | 38.4 MB | 76.8 MB |\\n| Load time | Instant (mmap) | ~10-20ms (conversion) |\\n\\n## Rollback Strategy\\n\\nEnvironment variable `CASS_F16_PRECONVERT=0` to:\\n- Keep F16 storage and mmap\\n- Convert per-query (original behavior)\\n- Useful for memory-constrained environments\\n\\n## Verification Plan\\n\\n1. Unit tests comparing search results with/without pre-convert\\n2. Benchmark comparison showing 40-50% speedup\\n3. Property-based test: `search(q).hits.map(|h| h.message_id) ≡ search_preconvert(q).hits.map(|h| h.message_id)`\\n\\n## Dependencies\\n\\n- None (first in chain)\\n- **Blocks**: Optimization 2 (SIMD) - SIMD works best on uniform F32 data\\n- **Blocks**: Optimization 3 (Parallel) - Parallel search benefits from pre-converted data\",\"status\":\"closed\",\"priority\":0,\"issue_type\":\"feature\",\"created_at\":\"2026-01-10T02:41:25.188716Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-01-10T06:42:31.549131Z\",\"closed_at\":\"2026-01-10T06:42:31.549131Z\",\"close_reason\":\"Opt 1 F16 Pre-Convert implemented and verified.

If power fails after the rename returns but before the tmp-file\\ndata reaches disk, the dirent `watch_state.json` points at a file whose\\ninode is allocated but whose data blocks are zeroed or partially\\npopulated.\\n\\n## Impact\\nwatch_state.json stores per-connector `last_message_id_ms` cursors.\\nLosing or zeroing it means on next start-up the indexer cannot resume\\nfrom the last-processed message and must either:\\n- re-walk every source from the beginning (expensive; hundreds of\\n  thousands of messages), or\\n- skip sources entirely if the code treats corrupt state as a hard\\n  error.\\n\\nLoss pattern matches exactly the class called out in j7hqe/92o31:\\n\\\"file appears empty after reboot despite a successful-looking write\\\".\\n\\n## Fix\\nEither:\\n(a) Route through the existing `write_json_pretty_atomically` helper\\n    (preferred — avoids duplicating fsync logic), or\\n(b) Inline the sync_all step before `replace_file_from_temp`:\\n\\n```\\nlet file = File::create(&tmp_path)?;\\nfile.write_all(&json)?;\\nfile.sync_all()?;\\ndrop(file);\\nreplace_file_from_temp(&tmp_path, &path)?;\\n```\\n\\n## Test\\nMirror the pattern from `pages::tests::write_file_durably_surfaces_parent_fsync_error`:\\nnegative-side guard that exercises the fsync code path and surfaces\\nthe error.

Explicit cleanup now flows through `cass doctor cleanup --json` preview and `cass doctor cleanup --yes --plan-fingerprint <fp> --json` apply. The tests now prove legacy `--fix` still emits JSON but does not enter `cleanup_apply` or prune retained publish backups/superseded generations.\\n- Cleanup preview/apply helpers parse JSON even when unrelated health checks are degraded, then assert branchable operation fields. This matches the operator contract: robot JSON remains the truth surface even when the process exit code reflects health failure.\\n- While verifying the doctor suite, found a first-principles storage bug: fresh DB creation used V13 fresh schema, then V15 altered `conversations` to add tail columns and V14 removed the derived FTS table. In frankensqlite this could leave duplicate/stray schema page state; C SQLite reported `PRAGMA integrity_check` failures such as `Page 41: never used` and duplicate provenance autoindex symptoms. That made supposedly healthy doctor fixtures fail as degraded archive risk.\\n- Fixed the fresh schema to include V15 `last_message_idx` / `last_message_created_at` columns up front, made the V15 migration idempotent for those columns, and removed the create-then-remove derived FTS table path from fresh schema. Fresh `fts_messages` remains lazy derived state, rebuilt by the existing consistency path when needed. Added a schema regression asserting the fresh DB has the V15 columns, no eager `fts_messages`, and passes `PRAGMA integrity_check`.\\n\\nVerification completed:\\n- `cargo test --lib storage::sqlite::tests::migration_v13_creates_analytics_tables -- --nocapture`\\n- `cargo test --lib doctor::tests -- --nocapture`\\n- `cargo test --test cli_doctor` (28/28 passed)\\n- Fresh external CLI repro: `cass index --force-rebuild --json` in a temp HOME followed by `sqlite3 <db> PRAGMA integrity_check;` returned `ok`; `fts_messages` schema row count was `0`.\\n- `cargo check --all-targets`\\n- `cargo clippy --all-targets -- -D warnings`\\n- `cargo fmt --check`\\n- `br sync --flush-only --json`, `br lint --json`, `br dep cycles --json`, and `bv --robot-alerts` all clean.\\n\\nStatus note: leaving the bead in progress rather than closing it because the acceptance text is broader than this implementation slice.

That pattern is useful for cass because many doctor regressions are not simple pass/fail changes: a user may want to know what changed since the last known-good archive health snapshot.\\n\\nProblem: cass doctor v2 will emit rich JSON, but without a baseline and diff workflow users and agents must manually compare reports. Manual comparison is fragile when reports include many assets, sources, backups, warnings, performance timings, anomaly classes, and support-bundle artifacts.\\n\\nScope: add a doctor baseline workflow that can save a redacted known-good report, compare the current report to a named baseline, and explain deltas. Baselines should include schema version, cass version, data dir identity, source ledger generation, archive generation, backup generations, derived index generations, anomaly classes, operation-log generation, selected redacted paths, and checksum of the redacted report. They must not include raw session content. Diffs should group changes by severity: new archive risk, resolved archive risk, new derived asset risk, lock/status change, source coverage change, backup freshness change, storage pressure change, performance regression, privacy/redaction change, support-bundle artifact change, and schema-only change. Baseline diff is diagnostic only: it must not mutate the live archive, update a baseline in-place, or repair anything unless a separate explicit save/update command is invoked.\\n\\nAcceptance criteria: provide robot fields for baseline_path, baseline_id, compared_at, added_anomalies, removed_anomalies, changed_assets, changed_recommendations, perf_delta, privacy_redaction_status, event_log_path, artifact_manifest_path, and baseline_mutated=false for diff. Human output should summarize what changed and the next best action. Unit tests cover redaction, stable diff ordering, missing baseline, incompatible schema, moved data dir, benign timestamp churn, event-log mismatch, manifest checksum drift, no-mutation diff behavior, and explicit baseline update behavior. E2E scenarios save a baseline, corrupt a derived index fixture, confirm the diff says derived-only rather than archive-loss, and emit logs/artifacts sufficient for support review.\\n\\nImplementation note: this is not a backup mechanism and must say so clearly.

If the ibuuh.24 architecture has chosen a\\n   different observability surface (e.g., the tracing-event stream\\n   + stall watchdog from ae411287), this module is vestigial.

Cass doctor needs that because repair, reconstruct, backup, and cleanup failures can be environment-sensitive: locks, disk pressure, platform rename semantics, permissions, fixture seeds, and source-pruning state all matter.\\n\\nProblem: the existing cass doctor plan has e2e scripts and artifact capture, but it also needs a compact failure_context artifact and a one-command repro path. Without that, future failures in doctor e2e or user support cases will require manual archaeology through logs and temp dirs.\\n\\nScope: when a doctor e2e scenario, repair run, or verification phase fails, write a failure_context.json artifact with command, argv, env allowlist, cass version, git revision when available, platform, temp/data dir paths, fixture seed, scenario id, operation id, active locks, selected authority, rejected authorities, plan fingerprint, failed phase, failed check, recent operation events, stdout/stderr paths, receipt path, and artifact manifest path. The repro command must avoid destructive behavior by default and should target the captured fixture or copied candidate, not the users live archive unless the operator explicitly points it there. Include a scrubbed shell-safe repro script or command JSON, not only prose.\\n\\nAcceptance criteria: e2e runner artifacts always include failure_context.json on failure. The artifact is redacted by default and has a schema/golden. Unit tests cover redaction, stable ordering, missing optional fields, command quoting, safe repro command construction, refusal to target live archives by default, and attachment to support bundles.

Output must avoid vague warnings and should clearly say what is safe, what is at risk, what cass will not do automatically, and what command to run next.\\n\\nScope: design concise human output for healthy, not initialized, source-pruned, DB-corrupt, index-corrupt, mirror-missing, repair-planned, repair-blocked, cleanup-planned, active-repair, backup/exclusion-risk, missing semantic model, and verification-failed states. Include sole-copy warnings such as cass appears to be the only remaining copy of N conversations.

It over-focused on three empty legacy shell files and a few misleading comments, while missing the actual user-facing incomplete behavior still present in the product.\\n\\n## Corrected Scope\\n\\nThis epic covers four different classes of work and keeps them separate so future implementers do not conflate them:\\n\\n### A. Real runtime gaps that affect users today\\nThese must be implemented or turned into explicit, truthful refusal paths:\\n- `models install --mirror` in `src/lib.rs` still hard-errors as not implemented.\\n- `analytics validate --fix` is advertised but the flag is currently ignored.\\n- Headless asciicast output currently uses a stub writer that emits a vacuous recording instead of a truthful artifact.\\n\\n### B. Misleading comments, stale tests, and confusing identity/no-op code\\nThese are not all equal. Some are harmless wording drift, while others create false mental models or dead code paths:\\n- stale `encrypt_content()` placeholder wording\\n- dead or misleading `dismiss_update()` semantics\\n- no-op `canonical()` view mapping\\n- phantom `_shared_filters` placeholder state\\n- stale docs/tests/help text that still claim shipped features are unimplemented\\n\\n### C. Intentionally retained shims, disabled features, and legacy shells\\nThese are not automatically bugs, but they must be made unmistakably intentional and truthfully surfaced to users and future agents:\\n- empty legacy shell modules under `src/ui/`\\n- disabled `search_sqlite_fts5()` fallback\\n- `include_attachments` being wired but rejected\\n- OPFS migration early-return in `pages_assets/storage.js`\\n- compatibility re-export wrappers and explicit no-op daemon fallbacks\\n\\n### D. System-level guardrails so this does not regress\\nThe repo needs automated detection and policy enforcement for incomplete-code markers, production manifest sentinels, and platform capability boundaries.\\n\\n## Important Constraint\\n\\nPer `AGENTS.md`, no file deletion is allowed without explicit written user permission. The three empty shell-file removal tasks therefore remain in this epic, but they are not executable until a dedicated permission-gate task is closed. If permission is not granted, the fallback is to keep those files as explicitly documented legacy shells rather than silently deleting them.\\n\\n## Strategy\\n\\n1. Fix the real runtime gaps first.\\n2. Clean up misleading docs/comments/tests and dead semantics next.\\n3. Reclassify intentional shims and disabled paths so they are clearly deliberate.\\n4. Encode the resulting policy in automated audits and verification.\\n5.

Check cass config, sources.toml, known local ignore files when relevant, repo-local .gitignore only when cass paths are under the repo, obvious rsync/restic/borg/rclone/git exclusion files if they are directly configured for cass, and environment/config choices that place archives under volatile cache directories.

evaluate in subtask)\\n- SSH probing via single-command script for efficiency\\n- Parallel probing with progress display\\n- Remote installation via cargo binstall (fast) or cargo install (reliable)\\n- Leverage existing sync engine for data transfer\\n- State persistence for resume capability\\n\\n## Error Handling Strategy\\n\\n### SSH Connection Failures\\n- **Timeout**: Show as \\\"unreachable\\\", allow user to retry or skip\\n- **Auth failure**: Show specific error, suggest `ssh-add` if key issue\\n- **Host key**: Accept new keys automatically (StrictHostKeyChecking=accept-new)\\n- **Partial failures**: Continue with working hosts, summarize failures at end\\n\\n### Installation Failures\\n- **No cargo**: Offer binary download alternative\\n- **Compilation error**: Show log excerpt, suggest checking dependencies\\n- **Disk full**: Detect upfront via probe, warn before attempting\\n- **Network timeout**: Installation runs in background, polls for completion\\n\\n### Indexing Failures\\n- **Index timeout**: Runs in background, polls for progress\\n- **Partial data**: Warn but continue (better to have some data than none)\\n- **Permissions**: Warn if some paths inaccessible\\n\\n### Config Failures\\n- **Invalid TOML**: Validate round-trip before writing\\n- **Backup failed**: Abort config write, preserve existing\\n- **Merge conflict**: Skip existing sources, show what was skipped\\n\\n### Recovery\\n- All progress saved to `~/.config/cass/setup_state.json`\\n- Resume with `cass sources setup --resume`\\n- Clear stuck state with `cass sources setup --resume --force`\\n\\n## Edge Cases\\n\\n### Many Hosts (50+)\\n- Search/filter capability essential\\n- Virtual scroll for large lists\\n- \\\"Select first N matching\\\" for batch operations\\n\\n### Slow Networks\\n- Longer timeouts for overseas hosts\\n- Progress indication during long operations\\n- Background operations with polling\\n\\n### Partial Access\\n- Some hosts accessible, others not\\n- Clear indication of what's working\\n- Continue with available hosts\\n\\n### Existing Configuration\\n- Detect already-configured hosts\\n- Show differently in UI (grayed out / badge)\\n- Don't duplicate, offer to update if wanted\\n\\n### Mixed cass Versions\\n- Remote has older cass than local\\n- Warn about potential compatibility issues\\n- Offer to upgrade remote\\n\\n### No Agent Data Found\\n- Host reachable but no session data detected\\n- Still allow configuration (user may know of custom paths)\\n- Lower in selection priority\\n\\n### Interrupted Setup\\n- Ctrl+C during probe: Safe, nothing changed\\n- Ctrl+C during install: State saved, resume continues\\n- Ctrl+C during config: State saved, resume skips install\\n- Ctrl+C during sync: Partial sync, re-run completes\\n\\n### Concurrent Runs\\n- Lock file prevents concurrent setup runs\\n- Clear error message if locked\\n\\n## Success Metrics\\n- Time to first cross-machine search: < 5 minutes from fresh install\\n- Zero manual file editing required\\n- Works with any SSH-accessible machine\\n- 90%+ of users succeed without consulting docs\\n\\n## Dependencies\\n- Existing SSH config discovery (done)\\n- Existing sync engine with tilde expansion (done)\\n- Interactive TUI crate (to be added -

That is the wrong product contract for AI-agent-first search. The desired contract is: hybrid intent should be the default experience, lexical search must always remain immediately available, and semantic refinement should opportunistically improve results without ever making ordinary search unusable.\\n\\nPRODUCT INTENT:\\n1. SQLite canonical DB is the sole source of truth.\\n2. Tantivy lexical index is a mandatory derivative artifact and must be rebuilt automatically from SQLite whenever missing, corrupt, schema-drifted, fingerprint-mismatched, or otherwise unusable.\\n3. Semantic/vector assets are optional derivative artifacts. Their absence must never break ordinary search; the system must fail open to lexical results.\\n4. Hybrid search should be the default behavior presented by the CLI/TUI/robot interface, but the default must preserve lexical immediacy and reliability.\\n5. Semantic backfill should happen in the background when the machine is idle or when work can be done within a strict performance budget, with pause/resume/checkpoint behavior.\\n6. Status/health/capabilities must report lexical readiness and semantic readiness separately, truthfully, and in a way that lets agents reason about whether they are seeing lexical-only or hybrid-refined results.\\n\\nWHY THIS MATTERS:\\nThe over-arching goal of cass is that a coding agent can point it at a canonical session history database and trust it to be searchable immediately, without needing to understand the implementation details of lexical vs semantic indexing. Search should not require a manual repair workflow. The system should self-heal mandatory search artifacts and opportunistically enrich itself in the background.\\n\\nSCOPE OF THIS EPIC:\\n- Redefine search/index asset ownership and state semantics\\n- Make lexical index regeneration automatic and safe\\n- Make hybrid the default search intent while failing open to lexical\\n- Add background semantic backlog tracking, scheduling, and resumable execution\\n- Add truthful observability for lexical vs semantic readiness\\n- Add exhaustive tests and operator docs\\n- Prove the design on the live canonical artifact after implementation\\n\\nNON-GOALS:\\n- Do not make semantic availability a prerequisite for ordinary search\\n- Do not require users/agents to memorize manual repair commands for lexical correctness\\n- Do not perform heavy background work aggressively enough to harm foreground coding or search latency\\n\\nSUCCESS CRITERIA FOR THE EPIC:\\n- A missing or invalid Tantivy index self-heals from the SQLite DB without user intervention.\\n- Ordinary cass search commands default to hybrid intent but still succeed quickly when semantic assets are absent.\\n- Background semantic backfill can resume across interruptions and converges to a fully indexed corpus.\\n- Health/status surfaces clearly distinguish lexical-ready, semantic-ready, and semantic-backfilling states.\\n- The implementation is covered by integration tests that simulate the real failure modes this epic is meant to eliminate.\\n\\nPLANNING NOTE:\\nThis epic is the source of truth for the new architecture.

] Overlapping highlights are properly merged\\n- [ ] Property tests verify match correctness\\n- [ ] Memory usage acceptable (Arc<str> overhead)\\n\\n## Considerations\\n- **Memory tradeoff:** Storing both original and lowercase doubles string memory\\n- **Arc<str>:** Enables efficient cloning without deep copy\\n- **Unicode edge cases:** Some characters change byte length when lowercased\\n- **QueryMatcher reuse:** Same query should reuse QueryMatcher across results\\n- **Lazy lowercasing:** Could compute lowercase on first access if memory is tight\\n\\n## Related Files\\n-

config files\\n  - `basic.config` - Simple host definitions\\n  - `wildcard.config` - Hosts with wildcards (should be filtered)\\n  - `many_hosts.config` - 50+ hosts for performance testing\\n- `probe_outputs/` - Sample probe outputs\\n  - `cass_installed.txt`\\n  - `cass_not_found.txt`\\n  - `partial_agents.txt`\\n  - `resource_info.txt`\\n- `sources_configs/` - Sample sources.toml configs\\n  - `empty.toml`\\n  - `existing_sources.toml`\\n  - `invalid.toml` - For error handling tests\\n- `mock_responses/` - Canned SSH responses\\n  - `install_success.txt`\\n  - `install_failure.txt`\\n  - `index_progress.txt`\\n\\n## Manual Test Plan (Interactive Elements)\\nSince dialoguer interactions can't be fully automated:\\n\\n### Pre-release checklist:\\n```\\n[ ] Fresh setup (no sources.toml)\\n    [ ] Run `cass sources setup`\\n    [ ] Verify hosts are discovered from ~/.ssh/config\\n    [ ] Verify probe status shown correctly\\n    [ ] Test search filtering (type letters, verify filter)\\n    [ ] Test select all / deselect all (a / n keys)\\n    [ ] Test space to toggle, enter to confirm\\n    [ ] Verify config preview is accurate\\n    [ ] Test \\\"Edit paths\\\" customization\\n    [ ] Test \\\"Add custom path\\\" flow\\n    [ ] Confirm save creates correct sources.toml\\n\\n[ ] Existing config (some sources already configured)\\n    [ ] Verify already-configured hosts shown differently\\n    [ ] Verify skip message for existing sources\\n    [ ] Verify new sources merge correctly\\n    [ ] Verify backup created\\n\\n[ ] Resume capability\\n    [ ] Start setup, Ctrl+C during probe phase\\n    [ ] Run setup again with --resume\\n    [ ] Verify resumes from correct point\\n\\n[ ] Non-interactive mode\\n    [ ] Run `cass sources setup --non-interactive --hosts css,csd`\\n    [ ] Verify no prompts\\n    [ ] Verify output is machine-parseable\\n\\n[ ] Error scenarios\\n    [ ] Test with unreachable host (should show error, continue others)\\n    [ ] Test with SSH key not loaded (should fail gracefully)\\n    [ ] Test with no cargo on remote (should suggest manual install)\\n```\\n\\n## Acceptance Criteria\\n- [ ] >80% code coverage for new modules\\n- [ ] All error paths have tests\\n- [ ] Integration test for happy path\\n- [ ] Integration tests for key failure modes\\n- [ ] Resume functionality tested\\n- [ ] Snapshot tests for config generation\\n- [ ] Performance test for parallel probing\\n- [ ] SSH layer abstracted for mocking\\n- [ ] Tests run in CI without real SSH\\n- [ ] Manual test plan documented and executed\\n\\n## Dependencies\\n- Requires: All component tasks to be implemented first\\n\\n## Considerations\\n- Testing SSH is inherently tricky (requires mock or real server)\\n- Consider testcontainers for SSH integration tests in CI\\n- SSH layer must be mockable via trait (design requirement)\\n- insta crate for snapshot testing\\n- Manual test plan should be run before each release\\n\\nLabels: [sources

A dedicated module boundary reduces accidental coupling and makes contracts testable. This is a structural refactor, not a compatibility layer: current command spellings should be routed into the new typed command model without leaving a duplicate legacy implementation.\\n\\nScope: move doctor data types, checks, plans, receipts, event-log integration, safety taxonomy, and repair execution into a src/doctor/ module or equivalent. Keep existing safe JSON entry points reachable while introducing internal seams for check, plan, repair, cleanup, backup, restore, reconstruct, baseline diff, support bundle, and report rendering. Centralize stdout/stderr, robot-mode contracts, outcome_kind mapping, and error envelopes so subcommands cannot drift. New SQLite logic must use frankensqlite/fsqlite patterns; do not add new rusqlite usage while moving code.\\n\\nAcceptance criteria: current cass doctor --json/--fix invocations route through the safer v2 parser/planner semantics; unsafe legacy assumptions fail closed instead of being preserved. Module tests can target doctor logic without invoking the full CLI; no new rusqlite usage is introduced; subcommand handlers share one parser/output/error contract.

Verify code_block bg is lighter than dark preset.\\n3. `test_markdown_theme_all_presets_produce_unique_themes` — Build markdown themes from all 6 presets, verify they differ (at minimum h1 fg should differ across presets).\\n4. `test_markdown_code_inline_has_background` — Verify code_inline has a non-None bg for all presets.\\n5. `test_markdown_code_block_has_background` — Verify code_block has a non-None bg for all presets.\\n6. `test_markdown_heading_contrast` — For each preset, verify h1-h6 have sufficient contrast against the code_block bg.\\n7. `test_markdown_link_is_underlined` — Verify link style includes underline attribute.\\n\\n### Snapshot tests:\\n8. `cassapp_detail_markdown_dark.snap` — Detail pane with markdown content (headers, code, links, list) in Dark preset\\n9. `cassapp_detail_markdown_light.snap` — Same content in Light preset\\n\\n### E2E validation:\\n10. `test_markdown_rendering_with_real_content` — Feed a realistic markdown conversation (with code blocks, headers, lists, links) into the detail pane renderer. Verify output has >= 3 distinct foreground colors (not monochrome). This catches the \\\"default theme\\\" regression.\\n\\n## Considerations\\n- **Performance**: MarkdownRenderer::new() is called per-render-cycle. The MarkdownTheme construction is just struct initialization (23 Style fields) — negligible cost. But the MarkdownRenderer itself may cache syntect state. Consider caching the renderer in CassApp and rebuilding only on theme change (CassMsg::ThemeChanged).\\n- **TableTheme**: The nested TableTheme has its own complex structure.

TUI list view: Only needs title/preview, not full content\\n\\n## Proposed Solution\\n\\nThread \\\"requested fields\\\" through the search pipeline and skip stored field hydration for unrequested fields.\\n\\n### Implementation Location\\n- File: `src/search/query.rs` (SearchClient::search)\\n- File: `src/search/tantivy.rs` (hit hydration logic)\\n- File: `src/lib.rs` (output formatting)\\n\\n### Implementation Strategy\\n\\n1. **Add FieldMask enum**:\\n```rust\\n#[derive(Clone, Copy)]\\npub enum FieldMask {\\n    Full,           // All fields\\n    Minimal,        // source_path, line_number, agent only\\n    SessionsOnly,   // Just source_path for deduplication\\n    CountOnly,      // No fields, just count\\n}\\n```\\n\\n2. **Modify SearchClient::search signature**:\\n```rust\\npub fn search(\\n    &self,\\n    query: &str,\\n    limit: usize,\\n    field_mask: FieldMask,  // NEW PARAMETER\\n) -> Result<SearchResult>\\n```\\n\\n3. **Conditional field hydration**:\\n```rust\\n// In hit hydration\\nmatch field_mask {\\n    FieldMask::Full => {\\n        // Load all stored fields (current behavior)\\n    }\\n    FieldMask::Minimal => {\\n        // Skip content, snippet, preview\\n        // Only load: source_path, line_number, agent, message_id\\n    }\\n    FieldMask::SessionsOnly => {\\n        // Only load source_path\\n    }\\n    FieldMask::CountOnly => {\\n        // Don't hydrate at all, just count matches\\n    }\\n}\\n```\\n\\n## Isomorphism Proof\\n\\nThis optimization preserves correctness because:\\n1. **Ranking is unchanged**: Scores come from Tantivy BM25, not stored fields\\n2. **Hit ordering is unchanged**: Order determined by query execution, not hydration\\n3. **Field independence**: Stored fields have no interdependencies\\n4. **Output correctness**: Only requested fields matter; others can be omitted\\n\\n### Formal Property\\nIf a field is not requested, not computing it cannot affect:\\n- Ranking/ordering (computed from Tantivy scores)\\n- Other fields (no dependencies between stored fields)\\n\\n## Expected Impact\\n\\n| Scenario | Before | After | Improvement |\\n|----------|--------|-------|-------------|\\n| `--fields minimal` | 100% stored field reads | ~20% stored field reads | ~5x less I/O |\\n| `--robot-format sessions` | Full hydration | Path-only | ~10x less I/O |\\n| Cold-open CLI search | Dominated by stored field reads | Much reduced | Noticeable |\\n\\nThe actual latency improvement depends on:\\n- How much of the 3.44% hotspot is skippable\\n- I/O vs CPU ratio on target hardware\\n- Index file layout (block alignment)\\n\\n## Implementation Notes\\n\\n### Backward Compatibility\\nNo external API changes needed. Internal refactor only. Default to `FieldMask::Full` for existing callers.\\n\\n### Threading Through the Stack\\nThe field mask needs to propagate:\\n1. CLI parsing (`--fields minimal`) → FieldMask\\n2. `run_search()` → `SearchClient::search(field_mask)`\\n3. `SearchClient` → Tantivy hit hydration\\n\\n### Already-Shipped Related Work\\nThe sessions output short-circuit (`src/lib.rs:3672`) already optimizes the *output* side by computing `BTreeSet<&str>` of source_paths. This optimization extends that pattern to the *input* side (stored field reads).\\n\\n## Verification Plan\\n\\n1. **Metamorphic test**: Same hit ordering for Full vs Minimal modes\\n2. **Field presence test**: Minimal mode returns correct fields, others are absent\\n3. **Benchmark**: Measure stored field read reduction with criterion\\n\\n## Rollback Strategy\\n\\nEnvironment variable `CASS_LAZY_FIELDS=0` to:\\n- Always hydrate all fields regardless of request\\n- Useful for debugging missing field issues\\n\\n## Dependencies\\n\\n- None (independent optimization)\\n- Can be implemented in parallel with P0 vector optimizations\",\"status\":\"closed\",\"priority\":1,\"issue_type\":\"feature\",\"created_at\":\"2026-01-10T03:01:12.249545Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-01-11T07:52:18.139055Z\",\"closed_at\":\"2026-01-11T07:52:18.139055Z\",\"close_reason\":\"Added FieldMask minimal metamorphic test (ordering + omitted fields) in tests/search_filters.rs\",\"source_repo\":\".\",\"compaction_level\":0,\"original_size\":0}\n{\"id\":\"coding_agent_session_search-m99lp\",\"title\":\"[MEDIUM] html_export: encrypted exports do not attach code copy buttons after decrypt\",\"description\":\"generate_init_js adds .copy-code-btn elements before encrypted content is decrypted.

For example:\\n- `é` (U+00E9) = precomposed\\n- `e` + `́` (U+0065 + U+0301) = decomposed\\n\\nNFC must see both codepoints before deciding on output. This requires buffering the entire string.\\n\\n**Mitigation**: NFC is typically cheap (~100-200µs for long messages). The savings come from eliminating the other 3-4 allocations.\\n\\n## Expected Impact\\n\\n| Metric | Before | After |\\n|--------|--------|-------|\\n| `canonicalize_long_message` | 951 µs | ~300 µs |\\n| Allocations per call | 5 | 2 |\\n| Index-time impact | Noticeable | Reduced |\\n\\n**Note**: This only affects index-time, not query-time. Lexical search doesn't use canonicalization.\\n\\n## Impact on Semantic Search Query Path\\n\\nThe query embedding path also calls `canonicalize_for_embedding` on the query text. Queries are typically short, so the impact is minimal. But the optimization applies equally.\\n\\n## Isomorphism Proof\\n\\nThe streaming version must produce byte-for-byte identical output:\\n1. **Same NFC normalization**: Same input → same NFC output\\n2. **Same markdown stripping**: Same rules, different implementation\\n3. **Same whitespace normalization**: Collapse runs, preserve word boundaries\\n4. **Same low-signal filtering**: Same heuristics\\n5. **Same truncation**: Same MAX_EMBED_CHARS limit\\n\\n### Verification\\n```rust\\n#[test]\\nfn streaming_matches_original() {\\n    for text in test_corpus() {\\n        let original = canonicalize_for_embedding(text);\\n        let streaming = canonicalize_for_embedding_streaming(text);\\n        assert_eq!(original, streaming, \\\"Mismatch for: {:?}\\\", text);\\n    }\\n}\\n```\\n\\n## Verification Plan\\n\\n1. **Equivalence test**: Original vs streaming produce identical output for test corpus\\n2. **content_hash test**: Hash of canonicalized output matches\\n3. **Benchmark**: Measure allocation reduction with criterion\\n4. **Property-based test**: Fuzz with arbitrary Unicode strings\\n\\n## Rollback Strategy\\n\\nEnvironment variable `CASS_STREAMING_CANONICALIZE=0` to:\\n- Use original multi-allocation implementation\\n- Useful for debugging canonicalization issues\\n\\n## Dependencies\\n\\n- None (index-time optimization, independent of search path)\\n- Can be implemented in parallel with vector search optimizations\",\"status\":\"closed\",\"priority\":2,\"issue_type\":\"feature\",\"created_at\":\"2026-01-10T03:02:10.211219Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-01-10T03:40:06.524555Z\",\"closed_at\":\"2026-01-10T03:40:06.524555Z\",\"close_reason\":\"Duplicate of 5p55 - consolidated\",\"source_repo\":\".\",\"compaction_level\":0,\"original_size\":0}\n{\"id\":\"coding_agent_session_search-nj5eh\",\"title\":\"[LOW] perf: truncate_content/apply_content_truncation does N×O(content_chars) work even on no-truncation path\",\"description\":\"profiling-software-performance PHASE-3 sweep on large-result-set robot mode.

(accessing 4 fields)\\n- [ ] No regression for detail-view queries (accessing all fields)\\n- [ ] >90% lazy parse ratio in TUI scroll scenarios\\n- [ ] All unit tests pass\\n- [ ] E2E tests verify correct data returned\\n- [ ] Memory usage not increased (Arc<str> vs owned String)\\n\\n## Considerations\\n- **Lifetime management:** Using Arc<str> for raw JSON allows safe sharing\\n- **OnceCell:** Provides thread-safe lazy initialization without mutex\\n- **Error propagation:** Lazy parse errors surface at access time, not creation\\n- **Backwards compatibility:** Existing code using full metadata still works\\n- **Debug builds:** Consider always parsing full in debug for validation\\n\\n## Related Files\\n- src/storage/sqlite.rs (main implementation)\\n- src/lib.rs

A random 256-bit Data Encryption Key (DEK) encrypts the data\\n2. The DEK is encrypted with a Key Encryption Key (KEK) derived from your password\\n3. Multiple key slots allow different passwords to decrypt the same data\\n\\n### Algorithms\\n\\n| Component | Algorithm | Parameters |\\n|-----------|-----------|------------|\\n| Data Encryption | AES-256-GCM | 96-bit nonce, 128-bit tag |\\n| Key Derivation | Argon2id | m={memory}KB, t={iterations}, p={parallelism} |\\n| DEK Encryption | AES-256-GCM | Same as data |\\n| Nonce Generation | Counter-based | Prevents reuse |\\n\\n### Key Slots\\n\\nThis archive has {slot_count} key slot(s):\\n{slot_descriptions}\\n\\nEach slot contains the same DEK encrypted with a different KEK.\\n\\n## Verification\\n\\n### Checking Archive Integrity\\n\\nThe AES-GCM authentication tag ensures:\\n- Data has not been modified\\n- Decryption used the correct key\\n\\nIf decryption fails, the archive was either:\\n- Corrupted in transit\\n- Modified by an attacker\\n- Decrypted with wrong key\\n\\n### Verifying Implementation\\n\\nThis archive was created with CASS, an open-source tool. You can:\\n1. Review the source code at {repo_url}\\n2. Verify the implementation uses standard libraries\\n3. Audit the cryptographic construction\\n\\n## Recommendations\\n\\n1. **Use a strong password**: 16+ characters, or 5+ random words\\n2. **Store recovery key safely**: It is the only backup\\n3. **Rotate passwords periodically**: Generate new archive with new key\\n4. **Limit distribution**: Share URL only with intended recipients\\n\\n## Contact\\n\\nFor security issues with CASS, see {repo_url}/security\\n\\n---\\nGenerated by CASS v{version}\\n```\\n\\n### help.html Template\\n\\nThis is an HTML page embedded in the web viewer:\\n\\n```html\\n<!DOCTYPE html>\\n<html lang=\\\"en\\\">\\n<head>\\n    <meta charset=\\\"UTF-8\\\">\\n    <title>Help - CASS Archive</title>\\n    <style>\\n        /* Embedded styles - no external dependencies */\\n        body { font-family: system-ui, sans-serif; max-width: 800px; margin: 0 auto; padding: 20px; }\\n        h1, h2, h3 { color: #333; }\\n        code { background: #f4f4f4; padding: 2px 6px; border-radius: 3px; }\\n        .warning { background: #fff3cd; padding: 10px; border-left: 4px solid #ffc107; }\\n        .info { background: #cce5ff; padding: 10px; border-left: 4px solid #007bff; }\\n    </style>\\n</head>\\n<body>\\n    <h1>Help</h1>\\n    \\n    <h2>Accessing the Archive</h2>\\n    <p>Enter your password in the unlock screen.

It refuses to rebuild from JSONL when the JSONL authority is unsafe, missing, newer than the DB in suspicious ways, or already failed verification. Cass needs the same discipline, but with more source classes: live upstream agent logs, the durable raw mirror, SQLite archive DB, WAL/SHM sidecars, source coverage ledger, remote sync copies, backup bundles, staged candidates, lexical indexes, semantic/vector indexes, and exported support bundles.\\n\\nProblem: a naive cass repair could choose the most convenient available input and accidentally rebuild a smaller archive after Claude, Codex, or another harness pruned its logs. The whole doctor v2 program exists because cass may be the only remaining archival copy. Rebuild authority therefore has to be explicit, testable, and fail-closed.\\n\\nScope: define a precedence matrix that says which artifact may repair or reconstruct which other artifact, under what freshness and coverage conditions, and with what refusal reason. Derived assets may be rebuilt from SQLite or verified candidate DBs. The SQLite archive may be reconstructed only from a verified raw mirror, verified backup, or a staged candidate that proves non-decreasing coverage. Live upstream source logs are useful evidence but are not automatically authoritative once pruning risk is detected. Remote sync copies require source identity, generation, and checksum validation before use. Backups must be verified before restore.\\n\\nAcceptance criteria: doctor reports include selected_authority, rejected_authorities with stable reasons, coverage_delta, freshness_delta, checksum evidence, and whether the decision is read-only, candidate-only, or promotable. Add unit tests for authority selection and refusal cases: source logs pruned, mirror missing, DB corrupt but mirror intact, backup stale, remote copy ahead, remote copy ambiguous, derived index corrupt, and candidate coverage lower than current archive. Add e2e coverage through the fixture factory for at least one pruned-upstream scenario.\\n\\nImplementation note: this bead should inform coverage gates, reconstruct, repair apply, safe auto-run, and health/status.

Approach\\n\\n### New Module: `src/pages/export.rs`\\n\\n```rust\\npub struct ExportFilter {\\n    pub agents: Option<Vec<String>>,      // Agent slugs to include\\n    pub workspaces: Option<Vec<PathBuf>>, // Workspace paths to include\\n    pub since: Option<DateTime<Utc>>,     // Start time filter\\n    pub until: Option<DateTime<Utc>>,     // End time filter\\n    pub path_mode: PathMode,              // relative|basename|full|hash\\n}\\n\\npub enum PathMode {\\n    Relative,  // Paths relative to workspace root (default)\\n    Basename,  // Filename only, no directory\\n    Full,      // Absolute paths (with warning)\\n    Hash,      // SHA256 of path (stealth mode)\\n}\\n\\npub struct ExportEngine {\\n    source_db: Connection,\\n    output_path: PathBuf,\\n    filter: ExportFilter,\\n}\\n\\nimpl ExportEngine {\\n    pub fn new(source: &Path, output: &Path, filter: ExportFilter) -> Result<Self>;\\n    pub fn execute(&self, progress: impl Fn(usize, usize)) -> Result<ExportStats>;\\n}\\n```\\n\\n### Export Logic\\n\\n1. **Query Source Database**:\\n   ```sql\\n   SELECT c.*, m.*\\n   FROM conversations c\\n   JOIN messages m ON m.conversation_id = c.id\\n   WHERE c.agent IN (?)\\n     AND c.workspace IN (?)\\n     AND c.started_at >= ?\\n     AND c.started_at <= ?\\n   ORDER BY c.started_at, m.idx\\n   ```\\n\\n2. **Transform Paths** based on PathMode:\\n   - `relative`: Strip workspace prefix from source_path\\n   - `basename`: Extract filename only\\n   - `full`: Keep as-is (emit warning)\\n   - `hash`: SHA256(source_path)[:16]\\n\\n3. **Write to Output Database** with web-optimized schema\\n\\n### Progress Reporting\\n\\nExport should report progress for large datasets:\\n```rust\\nprogress(conversations_processed, total_conversations);\\n```\\n\\n## Test Cases\\n\\n1. Filter by single agent → only that agent's conversations\\n2. Filter by multiple agents → union of conversations\\n3. Time range filter → only conversations in range\\n4. Workspace filter → only matching workspaces\\n5. No filters → all conversations\\n6. Empty result (no matches) → empty database with schema\\n7. PathMode::Hash → paths are opaque SHA256 prefixes\\n\\n## Files to Create/Modify\\n\\n- `src/pages/mod.rs` (new)\\n- `src/pages/export.rs` (new)\\n- `src/lib.rs` (add pages module)\\n- `tests/pages_export.rs` (new)\\n\\n## Exit Criteria\\n\\n1. ExportEngine produces valid filtered SQLite\\n2. All PathMode variants work correctly\\n3. Empty filters include all data\\n4. Progress callback invoked correctly\\n5. Unit tests cover all filter combinations\",\"status\":\"closed\",\"priority\":1,\"issue_type\":\"task\",\"created_at\":\"2026-01-07T01:29:57.036385Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-01-12T15:27:56.063072Z\",\"closed_at\":\"2026-01-12T15:27:56.063072Z\",\"close_reason\":\"Completed: Added 7 new tests covering all acceptance criteria: multiple agents filter, time range filter, workspace filter, empty result, PathMode::Basename, PathMode::Full, progress callback.

The existing open recovery bugs coding_agent_session_search-dl9so, coding_agent_session_search-4xf7t, and coding_agent_session_search-e34sr remain separate blockers/inputs for recovery-grade work.\\n\\nSUCCESS CRITERIA:\\nFuture implementation beads must include measured baselines, proof obligations, fallback triggers, artifact manifests, and user-visible responsiveness/resource-utilization gates.

Without such a callback, CASS can only mirror non-Codex directory-root files after parse succeeds, which defeats the sole-copy protection goal for parser failures.\\n\\nGoal: add an authoritative provider source-discovery contract to the FAD/CASS boundary so CASS can mirror every raw source file a connector is about to parse before parser code can drop, skip, or fail on it. This must cover local detected roots, configured local/remote roots, streaming index, batch index, and watch reindex paths.\\n\\nDesign direction: prefer adding an upstream FAD API such as Connector::discover_source_files(&ScanContext) -> Result<Vec<DiscoveredSourceFile>> or a scan_with_source_callback variant that emits source-file events before parse. The event payload should include provider slug, scan root identity, source path, source role/type (primary session log, message shard, metadata sidecar, sqlite/db file, attachment/part file if required), origin/source metadata if available, mtime/size when cheaply known, and whether the file is required for reconstructing the conversation. CASS should consume this event stream and call raw_mirror::capture_source_file before invoking parse. If the upstream dependency remains git-pinned, this bead must include updating Cargo.toml/Cargo.lock to the new reviewed rev and documenting the rev boundary.\\n\\nSafety constraints: do not add broad catch-all home-directory mirroring. Each connector must enumerate only files it actually treats as session evidence. Enumeration must not follow symlinks, must surface unreadable/deleted files as diagnostics without writing partial manifests, must respect since_ts filtering where the connector scan would, and must preserve current connector identity/external-id behavior.

A user may have remote source paths, stale sync state, unreachable SSH hosts, ambiguous remote identities, or mirrored local copies that are now the only surviving evidence. Doctor v2 should make those cases explicit instead of treating them as generic source errors.\\n\\nScope: extend source inventory, coverage ledger, health/status fields, and doctor reports to classify local sources, configured remote sources, last successful sync, missing remote source files, unreachable hosts, stale remote indexes, local archive ahead of remote, remote copy ahead with verified checksums, ambiguous remote identity, and local mirror-only coverage. Keep remote operations read-only unless the existing sources flow explicitly performs sync. Provide recommended actions that distinguish run sources sync, inspect remote, reconstruct from mirror, verify remote identity, and no action needed.\\n\\nAcceptance criteria: doctor check and status can report multi-machine coverage risk without blocking local archive recovery; robot JSON exposes remote_source_state and sync_staleness where known; docs explain that cass-owned mirror and DB evidence remain precious even when remotes disappear. Unit tests cover remote state classification and authority/refusal decisions. E2E fixtures or integration scripts cover remote source present/local mirror missing, local archive ahead of remote, remote copy ahead with verified checksums, ambiguous remote identity, SSH/source unavailable, stale sync, remote source pruned, and local mirror preserved states.

The overwhelming majority of messages contain NO secrets, but we still:\\n  1. Always allocate `input.to_string()` up front.\\n  2. Run all 12 regex scans sequentially over the full text.\\n  3. Each `replace_all(...).into_owned()` allocates a new String on every iteration, even when no match.\\n\\nAt scale this is called once per message across hundreds of thousands of messages.\\n\\nPROPOSED CHANGE:\\n1. Build a `Lazy<RegexSet>` matching the same 12 patterns as `SECRET_PATTERNS`. RegexSet compiles to a single Aho-Corasick-like scan over all patterns and returns which (if any) matched in one pass. See `regex::RegexSet`.\\n2. In redact_text, first call `SECRET_SET.matches(input)`. If `matched_any()` is false (the common case), return `Cow::Borrowed(input)` — no allocation, no scans.\\n3. If some patterns matched, only run `replace_all` for the subset of SECRET_PATTERNS whose indices are in `matches.iter()`. This reuses the existing regex instances.\\n4. Change the return type to `Cow<'_, str>` (or keep `String` and call `.into_owned()` on callers — trivial since most callers already convert).\\n\\nEXPECTED WIN:\\nFor message content WITHOUT secrets (95%+ of indexed content), eliminate 12 full regex scans + 12 String allocations per message. On a corpus of 500k messages that is a meaningful indexing throughput improvement — potentially 5-10x speedup in the redaction step, which becomes the bottleneck in tight indexing loops.\\n\\nVERIFICATION:\\n1. Existing tests in src/indexer/redact_secrets.rs must all pass unchanged (behavior is identical, only allocation pattern changes).\\n2. Add a micro-benchmark to `benches/index_perf.rs` comparing `redact_text(\\\"harmless content\\\")` before and after — should drop from ~O(12 scans) to ~O(1 set scan).\\n3.

The goal is to make `cass` the gold standard for how CLI tools should be designed for AI consumption.\\n\\n## Background & Motivation\\nAI agents (Claude, GPT-4, Codex, etc.) are increasingly being used to automate software development workflows. These agents interact with CLI tools through subprocess execution, parsing stdout/stderr. However, most CLI tools were designed for human users, creating friction:\\n\\n1. **Context Window Bloat**: AI agents have limited context windows (4K-200K tokens). A single search returning 10 results with full content can be 50KB+ of text, consuming precious context.\\n\\n2. **Parsing Uncertainty**: Agents need predictable, machine-readable output. Mixed log messages, inconsistent schemas, and undocumented fields cause parsing failures.\\n\\n3. **State Blindness**: Agents don't know if the index is stale, if they should retry, or what the system state is.\\n\\n4. **Workflow Friction**: Multi-step workflows (search → analyze → refine) require verbose command sequences.\\n\\n## Design Principles\\n1. **Context-Efficient by Default**: Every byte of output should earn its place\\n2. **Self-Documenting**: The CLI should explain itself completely\\n3. **Predictable**: Same inputs → same outputs, documented contracts\\n4. **Composable**: Easy to chain operations in workflows\\n5. **Fail-Informative**: Errors include actionable recovery information\\n\\n## Success Metrics\\n- 10x reduction in average response size with field selection\\n- Zero log pollution in robot mode outputs\\n- 100% schema coverage in introspection\\n- Sub-second status checks\\n\\n## Structure\\n- rob.ctx: Context Window Management (CRITICAL)\\n- rob.query: Query Intelligence\\n- rob.state: State Awareness\\n- rob.flow: Workflow Optimization\\n- rob.api: API Contract Clarity\\n- rob.safe: Reliability & Safety\\n\\n## Dependencies\\nThis epic builds on the existing robot mode infrastructure (--json, --robot, robot-docs).

The primary goal is achieving a **20-30x speedup** on semantic (vector) search while preserving exact search semantics.\\n\\n## Strategic Context\\n\\nCASS (Coding Agent Session Search) indexes conversations from Claude Code, Cursor, ChatGPT, Gemini, Aider, and other coding agents into a unified, searchable index. Performance is critical for:\\n- Interactive TUI responsiveness (target: <50ms for any search)\\n- Robot mode for AI agents consuming search results programmatically\\n- Batch operations like multi-machine sync and bulk indexing\\n\\n## The Problem: 56ms Vector Search Latency\\n\\nProfiling revealed the **semantic search path is the primary bottleneck**:\\n- `vector_index_search_50k`: **56.1ms** (vs 10.5µs for lexical search)\\n- Root cause: O(n×d) linear scan over 50k vectors with 384 dimensions each\\n- Additional overhead: F16→F32 conversion per dot product element\\n\\n## The Solution: Three-Stage Optimization Chain\\n\\nBy combining three complementary optimizations, we achieve multiplicative speedups:\\n\\n1. **F16 Pre-Convert** (56ms → 30ms): Eliminate per-query F16→F32 conversion by pre-converting at load time\\n2. **SIMD Dot Product** (30ms → 10-15ms): Explicit AVX2/SSE vectorization using `wide` crate\\n3. **Parallel Search** (10-15ms → 2-3ms): Rayon parallel scan with thread-local heaps\\n\\n## Hard Constraints (from AGENTS.md)\\n\\nAll implementations MUST follow these non-negotiables:\\n- NO FILE DELETION without explicit permission\\n- Cargo only; Rust edition 2024 nightly\\n- After substantive changes: `cargo fmt --check && cargo check --all-targets && cargo clippy --all-targets -- -D warnings && cargo test`\\n- One lever per change; no unrelated refactors\\n- Include rollback guidance (env vars for each optimization)\\n\\n## Equivalence Oracle\\n\\nFor optimization verification, outputs must match:\\n1. **Vector search**: Same (message_id, chunk_idx) set returned. Scores may differ by ~1e-7 relative error due to FP reordering with SIMD - acceptable for ranking.\\n2. **RRF fusion**: Deterministic tie-breaking by SearchHitKey ordering (already implemented).\\n3. **Canonicalization**: Byte-for-byte identical output (test with content_hash).\\n\\n## Success Metrics\\n\\n| Metric | Before | After | Validation |\\n|--------|--------|-------|------------|\\n| `vector_index_search_50k` | 56.1ms | 2-3ms | `cargo bench --bench vector_perf` |\\n| Memory (50k F16 vectors) | 38.4 MB | 76.8 MB | Acceptable 2x for 20x speedup |\\n| Search results | Baseline | Identical | Equivalence oracle tests |\\n\\n## Rollback Strategy\\n\\nEach optimization has an env var to disable:\\n- `CASS_F16_PRECONVERT=0`: Keep F16 storage, convert per-query\\n- `CASS_SIMD_DOT=0`: Fall back to scalar dot product\\n- `CASS_PARALLEL_SEARCH=0`: Use sequential scan\\n- `CASS_LAZY_FIELDS=0`: Hydrate all fields regardless of request\\n- `CASS_REGEX_CACHE=0`: Disable wildcard regex caching\\n- `CASS_STREAMING_CANONICALIZE=0`: Use original canonicalize function\\n- `CASS_SQLITE_CACHE=0`: Disable ID caching\\n\\n## Dependencies and Ordering\\n\\nThe P0 optimizations form a critical dependency chain:\\n- SIMD dot product benefits most AFTER F16 pre-convert (same data type throughout)\\n- Parallel search benefits most AFTER SIMD (parallelizing already-fast operation)\\n\\nP1/P2/P3 optimizations are largely independent and can proceed in parallel.\",\"status\":\"closed\",\"priority\":0,\"issue_type\":\"epic\",\"created_at\":\"2026-01-10T02:41:00.406693Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-01-10T06:53:59.353625Z\",\"closed_at\":\"2026-01-10T06:53:59.353625Z\",\"close_reason\":\"COMPLETED: Achieved 29x speedup (target was 20-30x).

issues with large batches\\n- [ ] Proper transaction rollback on failure\\n- [ ] Progress reporting for long operations\\n- [ ] Benchmark results documented\\n\\n## Considerations\\n- **SQLITE_MAX_VARIABLE_NUMBER:** Default 999, so max 333 rows with 3 columns\\n- **Transaction size:** Large transactions hold write lock longer\\n- **Memory:** Batch building allocates more memory temporarily\\n- **Error handling:** Partial batch failures need proper rollback\\n- **WAL mode:** Batching works best with WAL journaling mode\\n\\n## Related Files\\n- src/storage/sqlite.rs

Modern machines can hash >10 GB/s with xxhash3 or gxhash vs FNV-1a at ~1 GB/s.\\n\\nPROPOSED CHANGE:\\nReplace the body with `twox_hash::XxHash64` or the `gxhash` crate (both already transitive deps via frankensearch — verify with `cargo tree | grep -E 'xxhash|gxhash'`). Preserve the whitespace-invariant split semantics (iterate over split_whitespace tokens and feed them through the hasher with a space separator between tokens). Use a fixed seed (0) for deterministic cross-run output. The function is NOT on-disk format — grep confirms it feeds in-memory dedup HashMap keys and tests, so changing the hash value is safe (no schema migration).\\n\\nEXPECTED WIN:\\n4-10x faster hashing for long content bodies (~1-2 KB typical tool outputs). Each search with 100 hits computes ~100 hashes, so the saved µs add up. Also used by stable_hit_hash which is even hotter.\\n\\nVERIFICATION:\\n1. Before changing, run the full dedup test suite: `cargo test --lib -- resolve_semantic_doc_ids_for_hits_distinguishes`\\n2. After change, all of `cargo test --lib search::query::` must pass (includes the ~20 content_hash-consuming tests around lines 7835-11931).\\n3. Benchmark: add a criterion bench for `stable_content_hash` with 200/2000 char inputs if one doesn't exist, or measure via `search_perf::rrf_fusion_*` which consumes it transitively.\\n4. Update any test that hardcodes specific hash numeric output (`rg 'stable_content_hash\\\\(' tests/`).\\n\\nSAFETY NOTE:\\nConfirm stable_content_hash is not persisted to disk (message_docs / storage) — only used in-memory for dedup. grep src/storage and src/indexer before committing.\",\"status\":\"closed\",\"priority\":1,\"issue_type\":\"task\",\"created_at\":\"2026-04-22T19:46:14.489622644Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-04-22T20:00:41.300746599Z\",\"closed_at\":\"2026-04-22T20:00:41.300380744Z\",\"close_reason\":\"Replaced FNV-1a byte-loop in stable_content_hash + stable_hit_hash with xxhash_rust::xxh3::Xxh3 (xxh3-64).

The connector loads that key from CHATGPT_ENCRYPTION_KEY env var OR from one of three key file paths.\\n\\nFINDING (franken_agent_detection/src/connectors/chatgpt.rs:109-117): the key file load path uses fs::read() without ANY check on file permissions. A 32-byte AES-256 key file with mode 0644 (world-readable) or 0664 (group-readable) is loaded silently. SSH refuses to use a private key with mode > 0600 for exactly this reason (the key is as sensitive as a credit card number — it decrypts the user's entire ChatGPT history).\\n\\nSECURITY RATIONALE:\\n- The key decrypts the operator's full ChatGPT conversation history (potentially years of personal/professional content). Treating it like an SSH key is the obvious bar.\\n- Three paths searched in priority order; first match wins. If a process can write ~/.config/cass/chatgpt_key.bin with mode 0644, the connector will accept it. A multi-user system (shared dev box, lab machine) where one user's HOME is readable to others leaks the key.\\n- No symlink check either — a key file pointing to /dev/null or /etc/passwd would have its first 32 bytes loaded as a key (mostly harmless, decryption fails, but defense-in-depth says reject).\\n- CHATGPT_ENCRYPTION_KEY env var path has the same key-material concerns but is process-scoped (not on-disk persistent), so the file path is the higher-risk surface.\\n\\nATTACK SHAPE: Local privilege escalation / cross-user key disclosure on shared systems. Severity MEDIUM (requires local read access to the key file's directory).\\n\\nFix scope (~20 min):\\n1. After fs::read() succeeds, call std::os::unix::fs::MetadataExt::mode() on the file metadata, mask with 0o077 (group + other bits), refuse the load if any of those bits are set. Emit tracing::warn! pointing at the offending path and the offending mode bits.\\n2. Also tighten the load to check std::fs::symlink_metadata first and refuse symlinks (matches the ssh-key-loading discipline).\\n3.

Using ArrayVec avoids heap allocation since the maximum count\\nis known at compile time, reducing allocator pressure during bulk indexing.\\n\\n## Location\\n- **File:** src/search/tantivy.rs\\n- **Lines:** ~150-200 (edge_ngrams function)\\n- **Related:** Index building, tokenization pipeline\\n\\n## Current Implementation\\n```rust\\nfn edge_ngrams(word: &str) -> Vec<&str> {\\n    let mut ngrams = Vec::new();\\n    for len in 3..=20 {\\n        if word.len() >= len {\\n            ngrams.push(&word[..len]);\\n        }\\n    }\\n    ngrams\\n}\\n```\\n\\n## Problem Analysis\\n1. **Heap allocation:** Vec allocates on heap every call\\n2. **Known max size:** At most 18 n-grams (lengths 3 through 20)\\n3. **Hot path:** Called for every word during indexing (millions of calls)\\n4. **Allocation pressure:** Causes fragmentation and GC-like behavior\\n\\n## Proposed Solution\\n```rust\\nuse arrayvec::ArrayVec;\\n\\n/// Maximum number of edge n-grams per word\\n/// Lengths 3..=20 = 18 possible n-grams\\nconst MAX_EDGE_NGRAMS: usize = 18;\\n\\n/// Generate edge n-grams without heap allocation\\n/// \\n/// # Safety\\n/// This function assumes the input is valid UTF-8 that has been\\n/// normalized to ASCII or has been checked for valid char boundaries.\\n/// \\n/// # Example\\n/// ```\\n/// let ngrams = edge_ngrams_stack(\\\"hello\\\");\\n/// assert_eq!(ngrams.as_slice(), &[\\\"hel\\\", \\\"hell\\\", \\\"hello\\\"]);\\n/// ```\\npub fn edge_ngrams_stack(word: &str) -> ArrayVec<&str, MAX_EDGE_NGRAMS> {\\n    let mut ngrams = ArrayVec::new();\\n    let word_len = word.len();\\n    \\n    // Early exit for short words\\n    if word_len < 3 {\\n        return ngrams;\\n    }\\n    \\n    // Generate n-grams from length 3 to min(20, word_len)\\n    let max_len = word_len.min(20);\\n    for len in 3..=max_len {\\n        // SAFETY: We're slicing at byte boundaries.\\n        // The input has been ASCII-normalized by the tokenizer,\\n        // so all characters are single-byte.\\n        // For non-ASCII input, we use char_indices to find safe boundaries.\\n        if word.is_ascii() {\\n            ngrams.push(&word[..len]);\\n        } else {\\n            // Safe UTF-8 slicing for non-ASCII\\n            if let Some((idx, _)) = word.char_indices().nth(len) {\\n                ngrams.push(&word[..idx]);\\n            } else if word.chars().count() >= len {\\n                // Word has exactly 'len' chars, use entire string\\n                ngrams.push(word);\\n                break; // No longer n-grams possible\\n            }\\n        }\\n    }\\n    \\n    ngrams\\n}\\n\\n/// Iterator-based version (alternative, zero allocation)\\npub fn edge_ngrams_iter(word: &str) -> impl Iterator<Item = &str> {\\n    let word_len = word.len();\\n    let max_len = word_len.min(20);\\n    \\n    (3..=max_len).filter_map(move |len| {\\n        if word.is_ascii() {\\n            Some(&word[..len])\\n        } else {\\n            word.char_indices()\\n                .nth(len)\\n                .map(|(idx, _)| &word[..idx])\\n        }\\n    })\\n}\\n```\\n\\n## Implementation Steps\\n1. [ ] **Add arrayvec dependency:** `arrayvec = \\\"*\\\"` in Cargo.toml\\n2. [ ] **Implement edge_ngrams_stack:** With proper UTF-8 handling\\n3. [ ] **Add ASCII fast path:** Skip char_indices for ASCII words\\n4. [ ] **Benchmark both versions:** ArrayVec vs Iterator\\n5. [ ] **Replace in tokenizer:** Update all callsites\\n6. [ ] **Profile allocations:** Use DHAT to verify zero heap allocs\\n\\n## UTF-8 Safety Analysis\\nThe current tokenizer normalizes to ASCII/lowercase before n-gram generation.\\nHowever, we should handle edge cases:\\n\\n```rust\\n#[test]\\nfn test_utf8_safety() {\\n    // ASCII - direct slicing safe\\n    let ascii_ngrams = edge_ngrams_stack(\\\"hello\\\");\\n    assert_eq!(ascii_ngrams.len(),

That pattern is directly relevant to cass because a failed repair attempt can leave clues that should not be overwritten by another automated attempt.\\n\\nProblem: cass doctor v2 already plans dry-run fingerprints, receipts, forensic bundles, and atomic promotion, but it does not yet require a durable failed-repair marker that changes future behavior. Without that marker, an impatient user or automation loop could run doctor --fix repeatedly against the same fragile archive, producing noise and potentially obscuring the first failure evidence.\\n\\nScope: introduce a repair failure marker stored in the cass doctor state area. It must record operation id, command line mode, plan fingerprint, affected artifacts, selected authority, rejected authorities, preflight checks, applied actions, verification checks, failed checks, forensic bundle path, candidate path, timestamps, cass version, platform, and whether any user data was ever modified. Subsequent mutating repair commands must detect the marker and refuse the same repair class by default. Provide an explicit override flag such as --allow-repeated-repair or a more cass-specific equivalent, and require the new attempt to create a new operation id and preserve the previous marker.\\n\\nAcceptance criteria: robot output has stable fields: repair_previously_failed, failure_marker_path, repeat_refusal_reason, override_available, and override_used. Human output clearly says no further mutation was attempted. Unit tests cover marker creation, marker parsing, refusal, override, marker preservation, corrupt marker fallback, and multiple repair classes. E2E tests simulate a verification failure, rerun doctor --fix, prove it refuses by default, then prove an explicit override creates a second receipt without deleting the first marker.\\n\\nImplementation note: this gate should run before any candidate promotion or cleanup apply.

This function is called on every indexed message (src/indexer/semantic.rs:393, src/daemon/worker.rs:295), on every search hit that goes through semantic lookup (src/search/query.rs:3995, 4087, 7514), and once per query (src/search/query.rs:4656). DefaultCanonicalizer is a stateless struct with 3 usize fields (max_length, code_head_lines, code_tail_lines) — see /data/projects/frankensearch/crates/frankensearch-core/src/canonicalize.rs:58.

It performs a rollback-only write/read probe after repair. Cass should copy that first-principles idea: the only useful repair is one that leaves the archive and derived surfaces actually usable.\\n\\nProblem: cass doctor v2 currently has candidate verification and atomic promotion beads, but it does not explicitly require a post-repair probe that proves the promoted state can be opened, written, read, rolled back, and queried through the same pathways real cass commands use. A database can pass a superficial integrity check while still failing on writer locks, permissions, WAL behavior, migration state, or search hydration.\\n\\nScope: implement a post-repair probe suite that runs after any mutating doctor operation and before success is reported. For the SQLite archive, the probe should open through the production storage path, start a rollback-only transaction, insert or update a sentinel in a doctor-owned scratch/probe namespace, read it back, rollback, and verify no durable user-visible row was left behind. For derived lexical and semantic assets, probes should verify open, minimal query, generation identity, and consistency with the archive generation. For backups and candidates, probes should verify manifest checksums and restore-readability without promoting them.\\n\\nAcceptance criteria: robot output includes post_repair_probes with per-probe status, duration, failure reason, and whether failure blocked promotion or merely blocked cleanup.

Cass doctor already has beads for e2e scripts and golden tests, but the plan should require a discoverable developer interface so future agents can run the right subset without guessing.\\n\\nProblem: doctor v2 will span read-only checks, repair, reconstruct, restore, cleanup, auto-run, privacy, fault injection, and cross-platform filesystem behavior. If validation is only a collection of ad hoc test names, agents will either run too little or waste time running the wrong heavy suites. Worse, they may accidentally run tests against live user archives if the interface is not opinionated.\\n\\nScope: add a first-class validation surface for doctor scenarios. This can be a cargo xtask, scripts/doctor-e2e wrapper, or cass-internal test harness command, whichever best fits the repo, but it must provide list, describe, run, filter/include, exclude, force-build when relevant, artifact-dir, update-goldens, verify-goldens, fail-fast, keep-temp, json output, and scenario-manifest validation. It should classify scenarios by speed/risk labels and print the exact safe command to rerun a failure. It must never run bare cass TUI. It must default to safe fixture data and refuse to mutate live user archives unless an explicit test-only fixture path is provided.\\n\\nAcceptance criteria: agents can list doctor scenarios, inspect expected contracts, run one scenario, run a labeled group, capture artifacts, update reviewed goldens, and verify goldens using documented commands. The command output includes scenario id, fixture id, label set, expected mutation class, log paths, failure_context path on failure, and next suggested command. Unit tests or smoke tests cover CLI parsing, scenario discovery, manifest validation, refusal of unsafe live paths, and JSON output stability. E2E documentation includes example commands for common doctor development workflows and names which suites are quick enough for local use versus CI/release-only.\\n\\nImplementation note: this bead is about making verification operational.

It can rebuild lexical search from SQLite or from current source sessions. The risk is that upstream agent harnesses such as Codex and Claude may prune ~/.codex and ~/.claude logs, so cass may be the only remaining archival copy.

If the updater fires between the waiter's predicate check (line 7513) and the cv.wait call (line 7524), the notification is dropped (no parked waiters yet) and the waiter parks indefinitely waiting for a notification that already happened. Concrete interleaving: T1 waiter holds state-lock, evaluates max=5/inflight=10/req=3 → no fit, sets waited=true. T2 updater stores max=20 atomically + notify_all (zero subscribers). T1 calls cv.wait → parks. T1 hangs until next release() (which may never happen if no other tasks are holding bytes). Practical risk: LOW in steady-state traffic (release() on the holding task wakes T1 correctly), but real for capacity-shrink-then-grow patterns under low concurrency. Fix: have update_max_bytes_in_flight acquire self.state lock before storing and notifying, or use a single Mutex<(state,max)> and drop the AtomicUsize.

This \\ntells us:\\n- Whether index exists\\n- Session count\\n- Last index timestamp\\n- Index health\\n\\n### Skip Logic\\nSkip indexing if:\\n- cass health reports healthy index with sessions\\n- Index timestamp is recent (< 24 hours)\\n- User explicitly passed --skip-index\\n\\n### RemoteIndexer Implementation\\n```rust\\npub struct RemoteIndexer {\\n    host: String,\\n    ssh_timeout: u64,\\n}\\n\\npub struct IndexProgress {\\n    pub stage: IndexStage,\\n    pub message: String,\\n    pub sessions_found: u64,\\n    pub sessions_indexed: u64,\\n}\\n\\npub enum IndexStage {\\n    Starting,\\n    Scanning { agent: String },\\n    Building,\\n    Complete,\\n    Failed { error: String },\\n}\\n\\npub struct IndexResult {\\n    pub success: bool,\\n    pub sessions_indexed: u64,\\n    pub duration: Duration,\\n    pub error: Option<String>,\\n}\\n\\nimpl RemoteIndexer {\\n    /// Check if indexing is needed based on probe result\\n    pub fn needs_indexing(probe: &HostProbeResult) -> bool {\\n        match &probe.cass_status {\\n            CassStatus::NotFound => true,  // Just installed, needs index\\n            CassStatus::InstalledNotIndexed { .. } => true,\\n            CassStatus::Indexed { session_count, .. } => *session_count == 0,\\n            CassStatus::Unknown => true,\\n        }\\n    }\\n    \\n    /// Run indexing on remote host\\n    pub async fn run_index(\\n        &self,\\n        on_progress: impl Fn(IndexProgress),\\n    ) -> Result<IndexResult, IndexError> {\\n        let start = Instant::now();\\n        \\n        on_progress(IndexProgress {\\n            stage: IndexStage::Starting,\\n            message: \\\"Starting index...\\\".into(),\\n            sessions_found: 0,\\n            sessions_indexed: 0,\\n        });\\n        \\n        // Run cass index with streaming output\\n        let result = self.run_ssh_command_streaming(\\n            \\\"cass index --progress\\\",\\n            |line| {\\n                if let Some(progress) = parse_index_progress(&line) {\\n                    on_progress(progress);\\n                }\\n            }\\n        ).await?;\\n        \\n        // Get final count\\n        let health = self.run_ssh_command(\\\"cass health --json\\\").await?;\\n        let session_count = parse_session_count(&health);\\n        \\n        Ok(IndexResult {\\n            success: result.success,\\n            sessions_indexed: session_count,\\n            duration: start.elapsed(),\\n            error: result.error,\\n        })\\n    }\\n}\\n```\\n\\n### Long-Running Index Handling\\nFor hosts with many sessions (100k+), indexing can take 10+ minutes:\\n\\n```rust\\n/// For long indexes, use background execution with polling\\nasync fn run_long_index(&self, on_progress: impl Fn(IndexProgress)) -> Result<IndexResult> {\\n    // Start index in background\\n    self.run_ssh_command(\\\"nohup cass index > ~/.cass_index.log 2>&1 &\\\").await?;\\n    \\n    // Poll progress\\n    loop {\\n        let log = self.run_ssh_command(\\\"tail -20 ~/.cass_index.log\\\").await?;\\n        \\n        if let Some(progress) = parse_index_progress(&log) {\\n            on_progress(progress);\\n            \\n            if progress.stage == IndexStage::Complete {\\n                break;\\n            }\\n        }\\n        \\n        tokio::time::sleep(Duration::from_secs(2)).await;\\n    }\\n    \\n    // Get final result\\n    self.get_index_result().await\\n}\\n```\\n\\n### Progress Display\\n```\\nIndexing sessions on yto...\\n  Scanning ~/.claude/projects... found 234 sessions\\n  Scanning ~/.codex/sessions... found 12 sessions\\n  Scanning ~/.gemini/tmp... found 45 sessions\\n  \\n  Building search index...\\n  ████████████████████████████████████░░░░░░ 75% (219/291)\\n  \\n✓ Indexed 291 sessions on yto (45s)\\n```\\n\\n### Error Handling\\n```rust\\npub enum IndexError {\\n    SshFailed(String),\\n    CassNotFound,\\n    IndexFailed { \\n        stdout: String, \\n        stderr: String,\\n        exit_code: i32,\\n    },\\n    DiskFull,\\n    Timeout,\\n}\\n\\nfn handle_index_error(error: &IndexError) -> String {\\n    match error {\\n        IndexError::DiskFull => {\\n            \\\"Disk full on remote.

Those logs already live in cass as the unified, local knowledge base. The missing piece is **first-class analytics** so that humans and other agents can answer:\\n\\n- How many tokens did I spend per hour/day/week/month?\\n- Which agent(s) were responsible? Which project/workspace? Which machine/source?\\n- How much of that is **real provider usage** vs **content-length estimates**?\\n- What share of work is tool-heavy vs plan-heavy?\\n- What did this cost (USD) based on model pricing?\\n- Can I see these patterns as charts and drill down to the exact sessions/messages?\\n\\nDesign constraint: **local-only, privacy-respecting, derived-data rebuildable, and robot-first.**\\n\\n## Definitions (Avoid Confusion)\\n### Two Token Notions\\nWe must carry both throughout the system.\\n\\n1. **API usage tokens** (cost/compute relevant)\\n   - Source: provider usage blocks when available\\n   - Example: Claude Code `message.usage` exposes input/output/cache/thinking tokens\\n   - Used for cost estimation and “benchmark per MM tokens” questions\\n\\n2. **Content token estimate** (corpus/length relevant)\\n   - Source: message content itself (deterministic estimate)\\n   - Current heuristic: `content_chars / 4`\\n   - Applies to every connector uniformly, used for coverage + comparisons\\n\\n### Data Quality / Coverage\\nEvery aggregation must report:\\n- how many messages had real API usage\\n- how many used estimation fallback\\n- which connectors/models are missing token usage\\n\\nThis is not optional: analytics without coverage reporting becomes self-deception.\\n\\n## Data Sources (Connector Reality)\\n- Claude Code: rich `usage` blocks (input/output/cache/thinking + model)\\n- Codex: token_count events exist, but must be wired to assistant turns (see `z9fse.5`)\\n- Cursor/OpenCode/Factory/Pi-Agent/Gemini: often provide model names; token usage varies\\n- Others: often no token usage, rely on estimates\\n\\n## Storage: Current Reality (Two Analytics Tracks)\\nThe SQLite schema currently contains two parallel analytics tracks:\\n\\n### Track A: General Message Analytics\\n- `message_metrics` (fact table keyed by message_id)\\n- `usage_hourly` and `usage_daily` (rollups keyed by hour/day + agent/workspace/source)\\n\\nThis track supports:\\n- hour/day time series\\n- dimensions: agent_slug, workspace_id, source_id\\n- per-role counts for user/assistant (counts + content token est)\\n- tool_call_count (count only)\\n- has_plan + plan_message_count (count only)\\n\\n### Track B: Token Ledger + Model/Cost (Legacy/Parallel)\\n- `token_usage` (per-message ledger with model fields)\\n- `token_daily_stats` (daily rollups by day + agent_slug + source_id + model_family)\\n- `model_pricing` (pattern-based pricing table)\\n- conversations table has token summary columns (total tokens, estimated_cost_usd, etc)\\n\\nThis track supports:\\n- model-family breakdown\\n- per-conversation summaries\\n\\n### Critical Problem: Coherency\\n- Ingest currently populates BOTH Track A and Track B.\\n- Rebuild/backfill currently rebuilds ONLY Track A (`rebuild_analytics()` clears + repopulates message_metrics + usage_*).\\n- Cost estimation columns exist, but cost is not computed yet (estimated_cost_usd remains NULL/0).\\n\\nThis means it is possible for Track B to drift/stale. This must be fixed before analytics are exposed broadly.\\n\\n## Desired End State\\n1. **Single coherent analytics contract** surfaced via CLI and UI.\\n2. All derived analytics tables are either:\\n   - fully rebuildable from SQLite `messages`/`conversations`, OR\\n   - clearly deprecated and not used.\\n3. CLI and FrankenTUI use the same internal query layer so results match.\\n4. Tests enforce invariants and keep performance regressions out.\\n\\n## Query Semantics (Non-Negotiable)\\n- Buckets are UTC.\\n- Buckets are based on message created_at when available; fallback to conversation started_at.\\n- All commands must be robot-safe:\\n  - stdout = data only (JSON)\\n  - stderr = diagnostics\\n  - exit codes follow cass conventions\\n\\n## UX Plan (FrankenTUI)\\nAnalytics should be exposed as a dedicated **Analytics view** with:\\n\\n- A “recent activity” default (last 24h/7d) so it renders fast.\\n- A top filter strip consistent with search:\\n  - time range\\n  - source filter (local/remote/host)\\n  - agent filter\\n  - workspace filter\\n- A main dashboard with:\\n  - tokens over time (line/area)\\n  - coverage overlay (API vs estimated)\\n  - breakdown tables (agents/workspaces/models)\\n  - heatmap (daily sessions/messages)\\n\\nEverything must support drill-down:\\n- Select a bucket -> show the sessions/messages that contributed\\n- Jump back into the standard search/detail view\\n\\nAlso: analytics must never block interactive search.

The `pre` background is `oklch(0.08 0.015 260)` (very dark blue), and `pre code` color is `var(--foreground)` which is `oklch(0.95 0.01 260)` (near-white). In theory this should work, but the actual rendered result shows black-on-dark-blue text, making code blocks completely illegible.\\n\\n## Root Cause\\n\\nTwo interacting issues:\\n\\n1. **The `no-prism` fallback class is never applied.** The `onerror` handlers on the CDN script tags add the `no-prism` class (template.rs:288-321). But when `--no-cdns` is used, those script tags are never emitted, so the `onerror` handlers never fire, and the `no-prism` class is never added. The fallback CSS at template.rs:91-97 (`color: #c0caf5`) is dead code in the `--no-cdns` path.\\n\\n2. **No syntax highlighting at all.** Without Prism.js, all code is unstyled monochrome. The base `pre code` rule uses `var(--foreground)`, which should be light, but browser rendering of oklch colors in embedded styles may not work consistently, and the computed color contrast is poor.\\n\\n## Fix\\n\\nTwo changes needed:\\n\\n**A) Always add `no-prism` class when CDNs are disabled.** In template.rs, when `!options.include_cdn`, add `class=\\\"no-prism\\\"` to the `<html>` or `<body>` tag. This activates the fallback CSS.\\n\\n**B) Improve the fallback CSS itself.** The current fallback only sets `color: #c0caf5` on `code[class*=\\\"language-\\\"]`. It should also:\\n- Set a minimum-contrast foreground on ALL `pre code` elements (not just language-tagged ones)\\n- Include basic keyword highlighting via CSS-only rules for common tokens (optional but nice)\\n- Set `pre code { color: #c0caf5; }` unconditionally when no-prism is active\\n\\n## Files\\n\\n- `src/html_export/template.rs:83-98` (CDN_FALLBACK_CSS)\\n- `src/html_export/template.rs:274-332` (CDN script emission)\\n- `src/html_export/styles.rs:382-388` (pre code base styling)\",\"status\":\"closed\",\"priority\":1,\"issue_type\":\"bug\",\"created_at\":\"2026-03-18T21:05:12.300290793Z\",\"created_by\":\"ubuntu\",\"updated_at\":\"2026-03-18T22:34:12.185025632Z\",\"closed_at\":\"2026-03-18T22:34:12.184385032Z\",\"close_reason\":\"Fixed: --no-cdns now adds no-prism class to html tag + broadened fallback CSS to all pre code\",\"source_repo\":\".\",\"compaction_level\":0,\"original_size\":0}\n{\"id\":\"coding_agent_session_search-zz8ni\",\"title\":\"last_indexed_at writer race fails entire force-rebuild after successful index commit (src/indexer/mod.rs:6295)\",\"description\":\"## Symptom\\n\\n`cass index --full --force-rebuild --json` runs the full lexical rebuild successfully (51,214 documents in 222s), then exits with:\\n\\n```json\\n{\\\"success\\\": false,\\n \\\"error\\\": \\\"index failed: updating last_indexed_at after index run for /home/ubuntu/.local/share/coding-agent-search/agent_search.db | ephemeral writer preflight write failed for updating final last_indexed_at after index run at /home/ubuntu/.local/share/coding-agent-search/agent_search.db: database is busy.

    "path": "AGENTS.md",
    "content": "# AGENTS.md — coding_agent_session_search (cass)\n\n> Guidelines for AI coding agents working in this Rust codebase.\n\n---\n\n## RULE 0 - THE FUNDAMENTAL OVERRIDE PREROGATIVE\n\nIf I tell you to do something, even if it goes against what follows below, YOU MUST LISTEN TO ME. I AM IN CHARGE, NOT YOU.\n\n---\n\n## RULE NUMBER 1: NO FILE DELETION\n\n**YOU ARE NEVER ALLOWED TO DELETE A FILE WITHOUT EXPRESS PERMISSION.** Even a new file that you yourself created, such as a test code file. You have a horrible track record of deleting critically important files or otherwise throwing away tons of expensive work. As a result, you have permanently lost any and all rights to determine that a file or folder should be deleted.\n\n**YOU MUST ALWAYS ASK AND RECEIVE CLEAR, WRITTEN PERMISSION BEFORE EVER DELETING A FILE OR FOLDER OF ANY KIND.**\n\n---\n\n## Irreversible Git & Filesystem Actions — DO NOT EVER BREAK GLASS\n\n1. **Absolutely forbidden commands:** `git reset --hard`, `git clean -fd`, `rm -rf`, or any command that can delete or overwrite code/data must never be run unless the user explicitly provides the exact command and states, in the same message, that they understand and want the irreversible consequences.\n2. **No guessing:** If there is any uncertainty about what a command might delete or overwrite, stop immediately and ask the user for specific approval. \"I think it's safe\" is never acceptable.\n3. **Safer alternatives first:** When cleanup or rollbacks are needed, request permission to use non-destructive options (`git status`, `git diff`, `git stash`, copying to backups) before ever considering a destructive command.\n4. **Mandatory explicit plan:** Even after explicit user authorization, restate the command verbatim, list exactly what will be affected, and wait for a confirmation that your understanding is correct. Only then may you execute it—if anything remains ambiguous, refuse and escalate.\n5. **Document the confirmation:** When running any approved destructive command, record (in the session notes / final response) the exact user text that authorized it, the command actually run, and the execution time. If that record is absent, the operation did not happen.\n\n---\n\n## Git Branch: ONLY Use `main`, NEVER `master`\n\n**The default branch is `main`. The `master` branch exists only for legacy URL compatibility.**\n\n- **All work happens on `main`** — commits, PRs, feature branches all merge to `main`\n- **Never reference `master` in code or docs** — if you see `master` anywhere, it's a bug that needs fixing\n- **The `master` branch must stay synchronized with `main`** — after pushing to `main`, also push to `master`:\n  ```bash\n  git push origin main:master\n  ```\n\n**If you see `master` referenced anywhere:**\n1. Update it to `main`\n2. Ensure `master` is synchronized: `git push origin main:master`\n\n---\n\n## RULE NUMBER 2: ABSOLUTELY NO RUSQLITE IN NEW CODE — FRANKENSQLITE ONLY\n\n**THIS IS A HARD, NON-NEGOTIABLE RULE. IT HAS BEEN VIOLATED OVER 10 TIMES AND THE OWNER IS DONE TOLERATING IT.**\n\n- **ALL new SQLite code MUST use `frankensqlite` (`fsqlite`).** This applies to CASS, franken_agent_detection, and ANY project in this ecosystem.\n- **NEVER add `rusqlite` as a dependency.** NEVER write `use rusqlite::`. NEVER use `rusqlite::Connection`. Not even \"temporarily.\" Not even \"to match the existing pattern.\"\n- **The existing rusqlite usage is LEGACY DEBT**, not a pattern to follow. Do NOT copy it. Do NOT extend it.\n- **If frankensqlite is missing a feature you need, FIX FRANKENSQLITE.** It lives at `/data/projects/frankensqlite`. Add the missing API there. That is the entire point of the project.\n- **The frankensqlite API** uses `frankensqlite::Connection`, `fsqlite::compat::{ConnectionExt, RowExt, OpenFlags, open_with_flags, ParamValue}`, and `row.get_typed::<T>(idx)` instead of rusqlite's `row.get(idx)`.\n- **For franken_agent_detection connectors**: use `frankensqlite` with the compat layer. Import pattern:\n  ```rust\n  use frankensqlite::Connection as FrankenConnection;\n  use frankensqlite::compat::{ConnectionExt, RowExt, OpenFlags, open_with_flags, param_slice_to_values};\n  ```\n\n**If you are an AI agent reading this and you write `rusqlite` in new code, you are wasting the owner's time and money. This rule exists because agents have repeatedly ignored it. DO NOT BE THE NEXT ONE.**\n\n---\n\n## Toolchain: Rust & Cargo\n\nWe only use **Cargo** in this project, NEVER any other package manager.\n\n- **Edition:** Rust 2024 (stable — see `rust-toolchain.toml`)\n- **Dependency versions:** Wildcard constraints (`*`) for all crates\n- **Configuration:** Cargo.toml only (single-crate project, no workspace)\n- **Unsafe code:** Forbidden\n\n### Async Runtime: asupersync\n\nThis project uses **asupersync** as its async runtime (path dep at `../asupersync`). It provides `RuntimeBuilder`, `spawn_blocking`, `fs` ops, `net`, `signal`, and structured concurrency via `Cx`.\n\n### Environment Variables\n\nWe load all configuration from `.env` via the **dotenvy** crate. NEVER use `std::env::var()` directly.\n\n```rust\nuse dotenvy::dotenv;\nuse std::env;\n\n// Load .env file at startup (typically in main())\ndotenv().ok();\n\n// Configuration with fallback\nlet api_base_url = env::var(\"API_BASE_URL\")\n    .unwrap_or_else(|_| \"http://localhost:8007\".to_string());\n```\n\nThe `.env` file exists and **MUST NEVER be overwritten**.\n\n### Key Dependencies\n\n| Crate | Purpose |\n|-------|---------|\n| `asupersync` | Async runtime (multi-thread, fs, spawn_blocking, signals) — path dep |\n| `clap` | CLI argument parsing with derive macros |\n| `serde` + `serde_json` | Serialization |\n| `frankensqlite` (`fsqlite`) | Pure-Rust SQLite reimplementation — primary storage backend (path dep) |\n| `rusqlite` | SQLite database (bundled) — legacy, retained during frankensqlite migration |\n| `frankensearch` | Unified search engine: lexical BM25 + semantic + RRF fusion (path dep) |\n| `franken_agent_detection` | Agent session auto-detection across 15+ providers (path dep) |\n| `fastembed` | ONNX-based text embeddings |\n| `hnsw_rs` | HNSW approximate nearest neighbors |\n| `half` + `wide` + `memmap2` | f16 quantized vectors, portable SIMD, memory-mapped I/O |\n| `ftui` + `ftui-extras` | FrankenTUI terminal interface (path dep) |\n| `toon` | Terminal rendering library (path dep) |\n| `reqwest` | HTTP client (rustls-tls, blocking + async) |\n| `rayon` | Data parallelism for CPU-bound work |\n| `colored` + `indicatif` + `console` | Colorful, informative console output |\n| `notify` | Filesystem watching |\n| `walkdir` + `glob` | Directory traversal and pattern matching |\n| `blake3` + `sha2` | Cryptographic hashing |\n| `aes-gcm` + `ring` + `pbkdf2` + `argon2` | Encryption (ChatGPT conversations, HTML export) |\n| `ssh2` | SFTP fallback for multi-machine sync |\n| `dialoguer` | Interactive terminal prompts (setup wizard) |\n| `syntect` | Syntax highlighting |\n| `thiserror` | Ergonomic error type derivation |\n| `tracing` | Structured logging and diagnostics |\n| `unicode-normalization` | NFC text canonicalization |\n\n**Path dependencies** (sibling dirs under `/data/projects/`):\n- `frankensqlite` — Pure-Rust SQLite with BEGIN CONCURRENT (MVCC multi-writer)\n- `frankensearch` — Unified search: BM25 lexical + semantic embeddings + RRF fusion + reranking\n- `franken_agent_detection` — Auto-discovers agent sessions from 15+ providers\n- `frankentui` (`ftui` + `ftui-extras` + `ftui-runtime` + `ftui-tty`) — Terminal UI framework\n- `asupersync` — Async runtime (multi-thread, fs, spawn_blocking, signals)\n- `toon` — Token-optimized serialization\n\n### Release Profile\n\nThe release build optimizes for binary size (this is a CLI tool):\n\n```toml\n[profile.release]\nlto = true          # Link-time optimization\ncodegen-units = 1   # Single codegen unit for better optimization\nstrip = true        # Remove debug symbols\npanic = \"abort\"     # Abort on panic (smaller binary)\nopt-level = \"z\"     # Optimize for size\n```\n\nA profiling profile is also available:\n\n```toml\n[profile.profiling]\ninherits = \"release\"\ndebug = true        # Keep debug symbols for flamegraphs\nstrip = false\n```\n\n---\n\n## Code Editing Discipline\n\n### No Script-Based Changes\n\n**NEVER** run a script that processes/changes code files in this repo. Brittle regex-based transformations create far more problems than they solve.\n\n- **Always make code changes manually**, even when there are many instances\n- For many simple changes: use parallel subagents\n- For subtle/complex changes: do them methodically yourself\n\n### No File Proliferation\n\nIf you want to change something or add a feature, **revise existing code files in place**.\n\n**NEVER** create variations like:\n- `document_processorV2.rs`\n- `document_processor_improved.rs`\n- `document_processor_enhanced.rs`\n\nNew files are reserved for **genuinely new functionality** that makes zero sense to include in any existing file. The bar for creating new files is **incredibly high**.\n\n---\n\n## Backwards Compatibility\n\nWe do not care about backwards compatibility—we're in early development with no users. We want to do things the **RIGHT** way with **NO TECH DEBT**.\n\n- Never create \"compatibility shims\"\n- Never create wrapper functions for deprecated APIs\n- Just fix the code directly\n\n---\n\n## Console Output Style\n\nAll console output should be **informative, detailed, stylish, and colorful** by leveraging:\n- `colored` — ANSI color formatting\n- `indicatif` — Progress bars and spinners\n- `console` — Terminal utilities\n\n---\n\n## Compiler Checks (CRITICAL)\n\n**After any substantive code changes, you MUST verify no errors were introduced:**\n\n```bash\n# Check for compiler errors and warnings\ncargo check --all-targets\n\n# Check for clippy lints\ncargo clippy --all-targets -- -D warnings\n\n# Verify formatting\ncargo fmt --check\n```\n\nIf you see errors, **carefully understand and resolve each issue**. Read sufficient context to fix them the RIGHT way.\n\n---\n\n## Database Guidelines (frankensqlite + rusqlite)\n\nThe project is migrating from rusqlite to frankensqlite. Both are available:\n- `frankensqlite` (import as `fsqlite`) — Pure-Rust SQLite with BEGIN CONCURRENT support\n- `rusqlite` — C-binding SQLite, retained as fallback during migration\n\n### frankensqlite Patterns\n\n```rust\nuse frankensqlite::Connection;\n\n// Open with WAL mode (REQUIRED for concurrent access)\nlet conn = Connection::open(path)?;\nconn.execute(\"PRAGMA journal_mode = WAL;\")?;\nconn.execute(\"PRAGMA busy_timeout = 5000;\")?;\n\n// Use params! macro (needs explicit import)\nuse fsqlite::params;\nconn.execute_with_params(\"INSERT INTO t (a) VALUES (?1)\", params![42])?;\n```\n\n### Verified Standard SQLite File Reads\n\n`frankensqlite::Connection::open()` can open and read standard SQLite database files created by SQLite/rusqlite. That includes external app databases such as Cursor `state.vscdb`, OpenCode `opencode.db`, and historical cass databases.\n\n- Do not add `rusqlite` just to read an existing SQLite file.\n- If a specific query shape fails against one of these files, treat it as a targeted engine/query bug and file a reproducer instead of assuming the file format is unsupported.\n\n### FrankenConnectionManager (production pattern)\n\nUse `FrankenConnectionManager` for concurrent access:\n- Reader pool (multiple concurrent readers)\n- Writer token (single writer at a time via `WriterGuard`)\n- `WriterGuard` auto-rollbacks on drop (RAII safety)\n\n### Concurrent Writer Best Practices\n\n1. **Always use WAL mode** — without it, concurrent writes corrupt the DB\n2. **Use jittered exponential backoff** on `BusySnapshot` / `WriteConflict` errors\n3. **Batch writes** — 10-20 rows per transaction (not 1 row per commit)\n4. **Limit concurrent writers** to 4 threads (matches production rayon parallelism)\n5. **Retryable errors:** `Busy`, `BusyRecovery`, `BusySnapshot`, `WriteConflict`, `SerializationFailure`, `DatabaseCorrupt`\n\n### Known frankensqlite Differences\n\n- **File format interop:** As of rev `9cedb30b`, frankensqlite databases are\n  readable by C SQLite (rusqlite) and vice versa. Historical bundle salvage\n  still uses rusqlite as a proven read bridge for pre-migration databases.\n- **`PRAGMA writable_schema`:** Not supported for write operations (INSERT/UPDATE\n  on sqlite_master). SELECT from sqlite_master works.\n\n### General Rules\n\n**Do:**\n- Create connection pools and reuse across the application\n- Use `?` placeholders for parameters (prevents SQL injection)\n- Keep one database transaction per logical operation\n- Handle migrations properly\n- Use strong typing for database columns\n\n**Don't:**\n- Share a single transaction across concurrent tasks\n- Use string concatenation to build SQL queries\n- Ignore `Option<T>` for nullable columns\n- Mix sync and async database operations\n- Use `unwrap()` on database results in production code\n\n---\n\n## E2E Browser Tests\n\n**IMPORTANT:** E2E browser tests (Playwright) should only be run on GitHub Actions CI, NOT locally.\n\nRunning browser tests locally:\n- Consumes significant system resources (spawns browser instances)\n- Can freeze or slow down the development machine\n- May have different results than CI due to environment differences\n\n**Push to a branch and let GitHub Actions run the tests.** The CI workflow in `.github/workflows/browser-tests.yml` handles:\n- Installing browsers\n- Running tests in parallel across Chromium, Firefox, and WebKit\n- Uploading test artifacts and reports\n\nIf you need to debug a specific test, use `test.only()` and run a single spec file, but prefer CI for full test runs.\n\n---\n\n## Testing\n\n### Testing Policy\n\nTests must cover:\n- Happy path\n- Edge cases (empty input, max values, boundary conditions)\n- Error conditions\n\nIntegration and E2E tests live in the `tests/` directory. Benchmarks live in `benches/`.\n\n### Unit Tests\n\n```bash\n# Run all tests\ncargo test\n\n# Run with output\ncargo test -- --nocapture\n\n# Run a specific test\ncargo test test_name\n\n# Run tests with all features enabled\ncargo test --all-features\n```\n\n### Test Categories\n\n| Directory / File | Focus Areas |\n|-----------------|-------------|\n| `tests/connector_*.rs` | Per-provider session parsing (Claude, Codex, Cursor, Gemini, Aider, Amp, Cline, OpenCode, Pi Agent, Copilot, OpenClaw, ClawdBot, Vibe) |\n| `tests/search_*.rs` | Search pipeline, caching, filters, wildcard fallback |\n| `tests/semantic_integration.rs` | Semantic search, embeddings, two-tier search |\n| `tests/e2e_*.rs` | End-to-end CLI flows, filters, search, sources, TUI, deploy |\n| `tests/cli_*.rs` | CLI dispatch coverage, robot mode, index, stats |\n| `tests/tui_*.rs` | TUI headless smoke tests, snapshot tests |\n| `tests/tui_integration_smoke.rs` | TUI + full integrated stack (frankensqlite + frankensearch + FAD) |\n| `tests/frankensqlite_*.rs` | frankensqlite compat gates, concurrent stress tests |\n| `tests/agent_detection_completeness.rs` | franken_agent_detection connector completeness |\n| `tests/html_export*.rs` | HTML export pipeline, encryption |\n| `tests/storage*.rs` | SQLite storage, migration safety |\n| `tests/performance/` | Performance regression tests |\n| `benches/` | Criterion benchmarks (index, runtime, search, crypto, db, export, cache, regex, integration_regression) |\n\n### Test Fixtures\n\nFixtures are in `tests/fixtures/` and cover multiple agent session formats for cross-connector validation.\n\n---\n\n## Third-Party Library Usage\n\nIf you aren't 100% sure how to use a third-party library, **SEARCH ONLINE** to find the latest documentation and current best practices.\n\n---\n\n## cass — Coding Agent Session Search\n\n**This is the project you're working on.** cass indexes conversations from Claude Code, Codex, Cursor, Gemini, Aider, Amp, Cline, OpenCode, Pi Agent, Copilot, OpenClaw, ClawdBot, Vibe, and more into a unified, searchable index with a TUI and robot-mode CLI.\n\n**NEVER run bare `cass`** — it launches an interactive TUI. Always use `--robot` or `--json`.\n\n### What It Does\n\nProvides unified full-text and semantic search across all local coding agent session histories, with a rich TUI, robot-mode JSON API, multi-machine sync, HTML export with optional encryption, and analytics.\n\n### Search Asset Contract\n\n- **SQLite is the source of truth.** Search indexes are derived assets; do not treat a broken lexical or semantic artifact as lost user data.\n- **Lexical search is required and self-healing.** Missing, stale, schema-drifted, or corrupt lexical assets should rebuild from SQLite through scratch-build and atomic-publish semantics.\n- **Hybrid is the default search intent.** Semantic refinement joins when ready; default hybrid search must fail open to lexical with truthful robot metadata when semantic assets are unavailable.\n- **Semantic enrichment is opportunistic.** Lexical-only behavior is expected during first indexing, semantic backfill, disabled semantic policy, missing model files, or vector catch-up.\n- **Semantic model acquisition is opt-in.** `cass models install` downloads the MiniLM model (~90 MB) on explicit operator request. cass never auto-downloads. Air-gapped installs use `--from-file <dir>`. While the model is absent, `fallback_mode=\"lexical\"` is reported in health/status and queries silently degrade to lexical-only.\n- **Truth surfaces:** `cass health --json`, `cass status --json`, and search `--robot-meta` expose readiness, active rebuilds, realized search mode, fallback tier, and recommended action. Follow those fields instead of hard-coded manual repair rituals.\n\n### Lexical Publish Durability (Atomic-Swap)\n\n- Every lexical publish is a **single atomic swap**: on Linux `renameat2(RENAME_EXCHANGE)` exchanges the staged and live index trees in one syscall; non-Linux platforms use a parked-rename + restore-on-failure dance. Readers never see a half-torn index — either the old or the new generation is visible, never a mix.\n- The **prior-live generation is retained** under `<data_dir>/index/.lexical-publish-backups/<dated>/` for a bounded retention window. Default cap: `1` (one-step rollback). Override via `CASS_LEXICAL_PUBLISH_BACKUP_RETENTION` env var: `0` disables retention, `N` keeps the N most-recent backups. Pruning runs after every successful publish and emits `tracing::info!` with `freed_bytes`+`retention_limit`.\n- **Crash recovery is automatic.** If cass crashes between the atomic swap and the retain-rename, the next startup's `recover_or_finalize_interrupted_lexical_publish_backup` finds the canonical sidecar (`.<name>.publish-in-progress.bak`) and completes the retain step before the next publish. See src/indexer/mod.rs::publish_staged_lexical_index.\n- **Do not handwrite \"rebuild lexical\" recipes.** Call `cass index --full` or trust stale-refresh; the publish + atomic-swap + retention pipeline is the only blessed path. Anything that removes `<data_dir>/index/` directly outside publish is off-contract.\n\n### Quarantine, GC, and Doctor\n\n- Corrupt or failed-validation assets are **quarantined, not deleted**. Failed seed bundles, quarantined lexical generations, and superseded retained publish backups persist on disk until explicitly reclaimed.\n- `cass diag --json --quarantine` enumerates every quarantined artifact with `{path, size_bytes, age_seconds, last_read_at_ms, safe_to_gc, gc_reason}`. The `safe_to_gc` flag is **advisory only** — it reports retention-policy + cleanup-dry-run eligibility; no automatic deletion path consumes it.\n- `cass doctor --json` surfaces the same quarantine summary plus `checks[]` for every diagnostic. Without `--fix` doctor is read-only: `auto_fix_applied=false`, `auto_fix_actions=[]`, `issues_fixed=0`. With `--fix` it applies only repairs whose dry-run plans are proven safe — currently Track A analytics rebuild and Track B rollup rebuild via `rebuild_token_daily_stats` (when the `token_usage` ledger is intact; see bead m7xrw).\n- **Agents should not race doctor.** Running `cass doctor --fix` against an in-flight rebuild is safe (cass uses an advisory file lock), but concurrent `--fix` from two processes is undefined. Prefer `cass health --json` for pre-flight checks and `cass doctor --json` (no `--fix`) for inspection.\n\n### Schema Stability and Golden-Freeze Gates\n\n- Every JSON contract surface is pinned by golden-file regression tests under `tests/golden/robot/` (JSON) and `tests/golden/robot_docs/` (plain-text docs topics). The full set: capabilities, health, status, diag, diag_quarantine, models_status, models_verify, models_check_update, introspect, doctor, doctor_quarantine, api_version, stats (missing-db error envelope), robot_docs topics (paths, env, exit-codes, schemas, guide, robot_help).\n- **If you add a new field or change a type**, run `UPDATE_GOLDENS=1 cargo test --test golden_robot_json --test golden_robot_docs`, review the diff via `git diff tests/golden/`, and commit both the code + golden in one change. Do not regenerate goldens without reviewing — every diff is either an intentional schema change or a bug.\n- `cass introspect --json`'s `response_schemas` is `BTreeMap`-backed so the serialized key order is alphabetical and deterministic (bead 8sl73).\n- Error envelopes use **kebab-case `err.kind`** values. For codes 0-9 the numeric code is sufficient; for codes ≥ 10 the code is ambiguous (e.g. 10 covers both `config` and `timeout`) — always branch on `err.kind`. Full taxonomy in src/lib.rs `CliError` literals + the Exit Codes table below (bead wan21).\n\n### Project Structure\n\n```\ncoding_agent_session_search/\n├── Cargo.toml                    # Single-crate project\n├── src/\n│   ├── main.rs                   #

Exit 0 = success.**\n\n### Robot Mode Etiquette\n\n- Prefer `cass --robot-help` and `cass robot-docs <topic>` for machine-first docs\n- The CLI is forgiving: globals placed before/after subcommand are auto-normalized\n- If parsing fails, follow the actionable errors with examples\n- Use `--color=never` in non-TTY automation for ANSI-free output\n\n### Auto-Correction Features\n\n| Mistake | Correction | Note |\n|---------|------------|------|\n| `-robot` | `--robot` | Long flags need double-dash |\n| `--Robot`, `--LIMIT` | `--robot`, `--limit` | Flags are lowercase |\n| `find \"query\"` | `search \"query\"` | `find` is an alias |\n| `--robot-docs` | `robot-docs` | It's a subcommand |\n\n**Full alias list:**\n- **Search:** `find`, `query`, `q`, `lookup`, `grep` -> `search`\n- **Stats:** `ls`, `list`, `info`, `summary` -> `stats`\n- **Status:** `st`, `state` -> `status`\n- **Index:** `reindex`, `idx`, `rebuild` -> `index`\n- **View:** `show`, `get`, `read` -> `view`\n- **Robot-docs:** `docs`, `help-robot`, `robotdocs` -> `robot-docs`\n\n### Pre-Flight Health Check\n\n```bash\ncass health --json\n```\n\nReturns in <50ms:\n- **Exit 0:** Healthy — proceed with queries\n- **Exit 1:** Not ready — inspect `status`, `rebuild`, `semantic`, and `recommended_action`. Fresh installs usually need `cass index --full`; active rebuilds usually need bounded waiting; semantic-only gaps usually mean lexical fallback is expected.\n\n### Exit Codes\n\n| Code | Meaning | Retryable |\n|------|---------|-----------|\n| 0 | Success | N/A |\n| 1 | Health check failed | Yes — inspect `recommended_action` |\n| 2 | Usage/parsing error | No — fix syntax |\n| 3 | Index/DB missing | Yes — run `cass index --full` |\n| 4 | Network error | Yes — check connectivity |\n| 5 | Data corruption | Yes — inspect health/status, then rebuild derived assets if recommended |\n| 6 | Incompatible version | No — update cass |\n| 7 | Lock/busy | Yes — retry later |\n| 8 | Partial result | Yes — increase timeout |\n| 9 | Unknown error | Maybe |\n| 10 | Config / timeout (domain-specific) | Depends on `err.kind` |\n| 11 | Config validation | No — fix config |\n| 12 | Source / SSH problem | Maybe — check remote host |\n| 13 | Mapping / not-found | Depends on `err.kind` |\n| 14 | I/O / mapping | Maybe |\n| 15 | Semantic / embedder unavailable | Yes — install model or fall back to `--mode lexical` |\n| 20-21 | Model acquisition failure | Maybe — check `err.kind`, `err.hint` |\n| 22 | I/O during model handling | Maybe |\n| 23 | Download failure | Yes — retry or use `--from-file` |\n| 24 | I/O during model verify/install | Maybe |\n\n**Codes ≥ 10 are domain-specific.** The numeric code alone is ambiguous (e.g. code 10 covers both `config` and `timeout` kinds). Agents should branch on `err.kind` from the JSON error envelope, not on the numeric code, when handling codes ≥ 10. Kind names are kebab-case (examples: `missing-index`, `missing-db`, `semantic-unavailable`, `embedder-unavailable`, `ambiguous-source`, `timeout`, `config`, `lock-busy`, `network`, `model`, `download`, `io`). The full set (~50 kinds) lives in `src/lib.rs`.\n\n### Multi-Machine Search Setup\n\ncass can search across agent sessions from multiple machines. Use the interactive setup wizard for the easiest configuration:\n\n```bash\ncass sources setup\n```\n\n#### What the wizard does:\n1. **Discovers** SSH hosts from your ~/.ssh/config\n2. **Probes** each host to check for:\n   - Existing cass installation (and version)\n   - Agent session data (Claude, Codex, Cursor, Gemini)\n   - System resources (disk, memory)\n3. **Lets you select** which hosts to configure\n4. **Installs cass** on remotes if needed\n5. **Indexes** existing sessions on remotes\n6. **Configures** sources.toml with correct paths\n7. **Syncs** data to your local machine\n\n#### For scripting (non-interactive):\n```bash\ncass sources setup --non-interactive --hosts css,csd,yto\ncass sources setup --json --hosts css  # JSON output for parsing\n```\n\n#### Key flags:\n| Flag | Purpose |\n|------|---------|\n| `--hosts <names>` | Configure only these hosts (comma-separated) |\n| `--dry-run` | Preview without making changes |\n| `--resume` | Resume interrupted setup |\n| `--skip-install` | Don't install cass on remotes |\n| `--skip-index` | Don't run remote indexing |\n| `--skip-sync` | Don't sync after setup |\n| `--json` | Output progress as JSON |\n\n#### After setup:\n```bash\n# Search across all sources\ncass search \"database migration\"\n\n# Sync latest data\ncass sources sync --all\n\n# List configured sources\ncass sources list\n```\n\n#### Manual configuration:\nIf you prefer manual setup, edit `~/.config/cass/sources.toml`:\n```toml\n[[sources]]\nname = \"my-server\"\ntype = \"ssh\"\nhost = \"user@server.example.com\"\npaths = [\"~/.claude/projects\"]\n\n[[sources.path_mappings]]\nfrom = \"/home/user/projects\"\nto = \"/Users/me/projects\"\n```\n\n#### Troubleshooting:\n- **Host unreachable**: Verify SSH config with `ssh <host>` manually\n- **Permission denied**: Load SSH key with `ssh-add ~/.ssh/id_rsa`\n- **cargo not found**: Use `--skip-install` and install manually\n- **Interrupted setup**: Resume with `cass sources setup --resume`\n\nFor machine-readable docs: `cass robot-docs sources`\n\n### Feature Flags\n\n```toml\n[features]\ndefault = [\"qr\", \"encryption\"]\nqr = [\"dep:qrcode\", \"dep:image\"]         # QR code generation for recovery secret\nencryption = []                            # HTML export encryption (deps included for ChatGPT)\nbacktrace = []                             # Enhanced backtraces\n```\n\n---\n\n## MCP Agent Mail — Multi-Agent Coordination\n\nA mail-like layer that lets coding agents coordinate asynchronously via MCP tools and resources. Provides identities, inbox/outbox, searchable threads, and advisory file reservations with human-auditable artifacts in Git.\n\n### Why It's Useful\n\n- **Prevents conflicts:** Explicit file reservations (leases) for files/globs\n- **Token-efficient:** Messages stored in per-project archive, not in context\n- **Quick reads:** `resource://inbox/...`, `resource://thread/...`\n\n### Same Repository Workflow\n\n1. **Register identity:**\n   ```\n   ensure_project(project_key=<abs-path>)\n   register_agent(project_key, program, model)\n   ```\n\n2. **Reserve files before editing:**\n   ```\n   file_reservation_paths(project_key, agent_name, [\"src/**\"], ttl_seconds=3600, exclusive=true)\n   ```\n\n3. **Communicate with threads:**\n   ```\n   send_message(..., thread_id=\"FEAT-123\")\n   fetch_inbox(project_key, agent_name)\n   acknowledge_message(project_key, agent_name, message_id)\n   ```\n\n4. **Quick reads:**\n   ```\n   resource://inbox/{Agent}?project=<abs-path>&limit=20\n   resource://thread/{id}?project=<abs-path>&include_bodies=true\n   ```\n\n### Macros vs Granular Tools\n\n- **Prefer macros for speed:** `macro_start_session`, `macro_prepare_thread`, `macro_file_reservation_cycle`, `macro_contact_handshake`\n- **Use granular tools for control:** `register_agent`, `file_reservation_paths`, `send_message`, `fetch_inbox`, `acknowledge_message`\n\n### Common Pitfalls\n\n- `\"from_agent not registered\"`: Always `register_agent` in the correct `project_key` first\n- `\"FILE_RESERVATION_CONFLICT\"`: Adjust patterns, wait for expiry, or use non-exclusive reservation\n- **Auth errors:** If JWT+JWKS enabled, include bearer token with matching `kid`\n\n---\n\n## Beads (br) — Dependency-Aware Issue Tracking\n\nBeads provides a lightweight, dependency-aware issue database and CLI (`br` - beads_rust) for selecting \"ready work,\" setting priorities, and tracking status. It complements MCP Agent Mail's messaging and file reservations.\n\n**Important:** `br` is non-invasive—it NEVER runs git commands automatically. You must manually commit changes after `br sync --flush-only`.\n\n### Conventions\n\n- **Single source of truth:** Beads for task status/priority/dependencies; Agent Mail for conversation and audit\n- **Shared identifiers:** Use Beads issue ID (e.g., `br-123`) as Mail `thread_id` and prefix subjects with `[br-123]`\n- **Reservations:** When starting a task, call `file_reservation_paths()` with the issue ID in `reason`\n\n### Typical Agent Flow\n\n1. **Pick ready work (Beads):**\n   ```bash\n   br ready --json  # Choose highest priority, no blockers\n   ```\n\n2. **Reserve edit surface (Mail):**\n   ```\n   file_reservation_paths(project_key, agent_name, [\"src/**\"], ttl_seconds=3600, exclusive=true, reason=\"br-123\")\n   ```\n\n3. **Announce start (Mail):**\n   ```\n   send_message(..., thread_id=\"br-123\", subject=\"[br-123] Start: <title>\", ack_required=true)\n   ```\n\n4. **Work and update:** Reply in-thread with progress\n\n5. **Complete and release:**\n   ```bash\n   br close 123 --reason \"Completed\"\n   br sync --flush-only  # Export to JSONL (no git operations)\n   ```\n   ```\n   release_file_reservations(project_key, agent_name, paths=[\"src/**\"])\n   ```\n   Final Mail reply: `[br-123] Completed` with summary\n\n### Mapping Cheat Sheet\n\n| Concept | Value |\n|---------|-------|\n| Mail `thread_id` | `br-###` |\n| Mail subject | `[br-###] ...` |\n| File reservation `reason` | `br-###` |\n| Commit messages | Include `br-###` for traceability |\n\n---\n\n## bv — Graph-Aware Triage Engine\n\nbv is a graph-aware triage engine for Beads projects (`.beads/beads.jsonl`). It computes PageRank, betweenness, critical path, cycles, HITS, eigenvector, and k-core metrics deterministically.\n\n**Scope boundary:** bv handles *what to work on* (triage, priority, planning). For agent-to-agent coordination (messaging, work claiming, file reservations), use MCP Agent Mail.\n\n**CRITICAL: Use ONLY `--robot-*` flags. Bare `bv` launches an interactive TUI that blocks your session.**\n\n### The Workflow: Start With Triage\n\n**`bv --robot-triage` is your single entry point.** It returns:\n- `quick_ref`: at-a-glance counts + top 3 picks\n- `recommendations`: ranked actionable items with scores, reasons, unblock info\n- `quick_wins`: low-effort high-impact items\n- `blockers_to_clear`: items that unblock the most downstream work\n- `project_health`: status/type/priority distributions, graph metrics\n- `commands`: copy-paste shell commands for next steps\n\n```bash\nbv --robot-triage        # THE MEGA-COMMAND: start here\nbv --robot-next          # Minimal: just the single top pick + claim command\n```\n\n### Command Reference\n\n**Planning:**\n| Command | Returns |\n|---------|---------|\n| `--robot-plan` | Parallel execution tracks with `unblocks` lists |\n| `--robot-priority` | Priority misalignment detection with confidence |\n\n**Graph Analysis:**\n| Command | Returns |\n|---------|---------|\n| `--robot-insights` | Full metrics: PageRank, betweenness, HITS, eigenvector, critical path, cycles, k-core, articulation points, slack |\n| `--robot-label-health` | Per-label health: `health_level`, `velocity_score`, `staleness`, `blocked_count` |\n| `--robot-label-flow` | Cross-label dependency: `flow_matrix`, `dependencies`, `bottleneck_labels` |\n| `--robot-label-attention [--attention-limit=N]` | Attention-ranked labels |\n\n**History & Change Tracking:**\n| Command | Returns |\n|---------|---------|\n| `--robot-history` | Bead-to-commit correlations |\n| `--robot-diff --diff-since <ref>` | Changes since ref: new/closed/modified issues, cycles |\n\n**Other:**\n| Command | Returns |\n|---------|---------|\n| `--robot-burndown <sprint>` | Sprint burndown, scope changes, at-risk items |\n| `--robot-forecast <id\\|all>` | ETA predictions with dependency-aware scheduling |\n| `--robot-alerts` | Stale issues, blocking cascades, priority mismatches |\n| `--robot-suggest` | Hygiene: duplicates, missing deps, label suggestions |\n| `--robot-graph [--graph-format=json\\|dot\\|mermaid]` | Dependency graph export |\n| `--export-graph <file.html>` | Interactive HTML visualization |\n\n### Scoping & Filtering\n\n```bash\nbv --robot-plan --label backend              # Scope to label's subgraph\nbv --robot-insights --as-of HEAD~30          # Historical point-in-time\nbv --recipe actionable --robot-plan          # Pre-filter: ready to work\nbv --recipe high-impact --robot-triage       # Pre-filter: top PageRank\nbv --robot-triage --robot-triage-by-track    # Group by parallel work streams\nbv --robot-triage --robot-triage-by-label    # Group by domain\n```\n\n### Understanding Robot Output\n\n**All robot JSON includes:**\n- `data_hash` — Fingerprint of source beads.jsonl\n- `status` — Per-metric state: `computed|approx|timeout|skipped` + elapsed ms\n- `as_of` / `as_of_commit` — Present when using `--as-of`\n\n**Two-phase analysis:**\n- **Phase 1 (instant):** degree, topo sort, density\n- **Phase 2 (async, 500ms timeout):** PageRank, betweenness, HITS, eigenvector, cycles\n\n### jq Quick Reference\n\n```bash\nbv --robot-triage | jq '.quick_ref'                        # At-a-glance summary\nbv --robot-triage | jq '.recommendations[0]'               # Top recommendation\nbv --robot-plan | jq '.plan.summary.highest_impact'        # Best unblock target\nbv --robot-insights | jq '.status'                         # Check metric readiness\nbv --robot-insights | jq '.Cycles'                         # Circular deps (must fix!)\n```\n\n---\n\n## UBS — Ultimate Bug Scanner\n\n**Golden Rule:** `ubs <changed-files>` before every commit. Exit 0 = safe. Exit >0 = fix & re-run.\n\n### Commands\n\n```bash\nubs file.rs file2.rs                    # Specific files (< 1s) — USE THIS\nubs $(git diff --name-only --cached)    # Staged files — before commit\nubs --only=rust,toml src/               # Language filter (3-5x faster)\nubs --ci --fail-on-warning .            # CI mode — before PR\nubs .                                   # Whole project (ignores target/, Cargo.lock)\n```\n\n### Output Format\n\n```\nWarning  Category (N errors)\n    file.rs:42:5 - Issue description\n    Suggested fix\nExit code: 1\n```\n\nParse: `file:line:col` -> location | Suggested fix -> how to fix | Exit 0/1 -> pass/fail\n\n### Fix Workflow\n\n1.

Re-run `ubs <file>` -> exit 0\n6. Commit\n\n### Bug Severity\n\n- **Critical (always fix):** Memory safety, use-after-free, data races, SQL injection\n- **Important (production):** Unwrap panics, resource leaks, overflow checks\n- **Contextual (judgment):** TODO/FIXME, println! debugging\n\n---\n\n## RCH — Remote Compilation Helper\n\nRCH offloads `cargo build`, `cargo test`, `cargo clippy`, and other compilation commands to a fleet of 8 remote Contabo VPS workers instead of building locally. This prevents compilation storms from overwhelming csd when many agents run simultaneously.\n\n**RCH is installed at `~/.local/bin/rch` and is hooked into Claude Code's PreToolUse automatically.** Most of the time you don't need to do anything if you are Claude Code — builds are intercepted and offloaded transparently.\n\nTo manually offload a build:\n```bash\nrch exec -- cargo build --release\nrch exec -- cargo test\nrch exec -- cargo clippy\n```\n\nQuick commands:\n```bash\nrch doctor                    # Health check\nrch workers probe --all       # Test connectivity to all 8 workers\nrch status                    # Overview of current state\nrch queue                     # See active/waiting builds\n```\n\nIf rch or its workers are unavailable, it fails open — builds run locally as normal.\n\n**Note for Codex/GPT-5.2:** Codex does not have the automatic PreToolUse hook, but you can (and should) still manually offload compute-intensive compilation commands using `rch exec -- <command>`. This avoids local resource contention when multiple agents are building simultaneously.\n\n---\n\n## ast-grep vs ripgrep\n\n**Use `ast-grep` when structure matters.** It parses code and matches AST nodes, ignoring comments/strings, and can **safely rewrite** code.\n\n- Refactors/codemods: rename APIs, change import forms\n- Policy checks: enforce patterns across a repo\n- Editor/automation: LSP mode, `--json` output\n\n**Use `ripgrep` when text is enough.** Fastest way to grep literals/regex.\n\n- Recon: find strings, TODOs, log lines, config values\n- Pre-filter: narrow candidate files before ast-grep\n\n### Rule of Thumb\n\n- Need correctness or **applying changes** -> `ast-grep`\n- Need raw speed or **hunting text** -> `rg`\n- Often combine: `rg` to shortlist files, then `ast-grep` to match/modify\n\n### Rust Examples\n\n```bash\n# Find structured code (ignores comments)\nast-grep run -l Rust -p 'fn $NAME($$$ARGS) -> $RET { $$$BODY }'\n\n# Find all unwrap() calls\nast-grep run -l Rust -p '$EXPR.unwrap()'\n\n# Quick textual hunt\nrg -n 'println!' -t rust\n\n# Combine speed + precision\nrg -l -t rust 'unwrap\\(' | xargs ast-grep run -l Rust -p '$X.unwrap()' --json\n```\n\n---\n\n## Morph Warp Grep — AI-Powered Code Search\n\n**Use `mcp__morph-mcp__warp_grep` for exploratory \"how does X work?\" questions.** An AI agent expands your query, greps the codebase, reads relevant files, and returns precise line ranges with full context.\n\n**Use `ripgrep` for targeted searches.** When you know exactly what you're looking for.\n\n**Use `ast-grep` for structural patterns.** When you need AST precision for matching/rewriting.\n\n### When to Use What\n\n| Scenario | Tool | Why |\n|----------|------|-----|\n| \"How is authentication implemented?\" | `warp_grep` | Exploratory; don't know where to start |\n| \"Where is rate limiting implemented?\" | `warp_grep` | Need to understand architecture |\n| \"Find all uses of `embed(`\" | `ripgrep` | Targeted literal search |\n| \"Find files with `println!`\" | `ripgrep` | Simple pattern |\n| \"Replace all `unwrap()` with `expect()`\" | `ast-grep` | Structural refactor |\n\n### warp_grep Usage\n\n```\nmcp__morph-mcp__warp_grep(\n  repoPath: \"/dp/coding_agent_session_search\",\n  query: \"How is semantic search implemented?\"\n)\n```\n\nReturns structured results with file paths, line ranges, and extracted code snippets.\n\n### Anti-Patterns\n\n- **Don't** use `warp_grep` to find a specific function name -> use `ripgrep`\n- **Don't** use `ripgrep` to understand \"how does X work\" -> wastes time with manual reads\n- **Don't** use `ripgrep` for codemods -> risks collateral edits\n\n<!-- bv-agent-instructions-v1 -->\n\n---\n\n## Beads Workflow Integration\n\nThis project uses [beads_rust](https://github.com/Dicklesworthstone/beads_rust) (`br`) for issue tracking. Issues are stored in `.beads/` and tracked in git.\n\n**Important:** `br` is non-invasive—it NEVER executes git commands. After `br sync --flush-only`, you must manually run `git add .beads/ && git commit`.\n\n### Essential Commands\n\n```bash\n# View issues (launches TUI - avoid in automated sessions)\nbv\n\n# CLI commands for agents (use these instead)\nbr ready              # Show issues ready to work (no blockers)\nbr list --status=open # All open issues\nbr show <id>          # Full issue details with dependencies\nbr create --title=\"...\" --type=task --priority=2\nbr update <id> --status=in_progress\nbr close <id> --reason \"Completed\"\nbr close <id1> <id2>  # Close multiple issues at once\nbr sync --flush-only  # Export to JSONL (NO git operations)\n```\n\n### Workflow Pattern\n\n1. **Start**: Run `br ready` to find actionable work\n2. **Claim**: Use `br update <id> --status=in_progress`\n3. **Work**: Implement the task\n4. **Complete**: Use `br close <id>`\n5. **Sync**: Run `br sync --flush-only` then manually commit\n\n### Key Concepts\n\n- **Dependencies**: Issues can block other issues. `br ready` shows only unblocked work.\n- **Priority**: P0=critical, P1=high, P2=medium, P3=low, P4=backlog (use numbers, not words)\n- **Types**: task, bug, feature, epic, question, docs\n- **Blocking**: `br dep add <issue> <depends-on>` to add dependencies\n\n### Session Protocol\n\n**Before ending any session, run this checklist:**\n\n```bash\ngit status              # Check what changed\ngit add <files>         # Stage code changes\nbr sync --flush-only    # Export beads to JSONL\ngit add .beads/         # Stage beads changes\ngit commit -m \"...\"     # Commit everything together\ngit push                # Push to remote\n```\n\n### Best Practices\n\n- Check `br ready` at session start to find available work\n- Update status as you work (in_progress -> closed)\n- Create new issues with `br create` when you discover tasks\n- Use descriptive titles and set appropriate priority/type\n- Always `br sync --flush-only && git add .beads/` before ending session\n\n<!-- end-bv-agent-instructions -->\n\n## Landing the Plane (Session Completion)\n\n**When ending a work session**, you MUST complete ALL steps below.\n\n**MANDATORY WORKFLOW:**\n\n1. **File issues for remaining work** - Create issues for anything that needs follow-up\n2. **Run quality gates** (if code changed) - Tests, linters, builds\n3. **Update issue status** - Close finished work, update in-progress items\n4. **Sync beads** - `br sync --flush-only` to export to JSONL\n5. **Hand off** - Provide context for next session\n\n---\n\n## cass — Cross-Agent Session Search\n\n`cass` indexes prior agent conversations (Claude Code, Codex, Cursor, Gemini, ChatGPT, etc.) so we can reuse solved problems.\n\n**Rules:** Never run bare `cass` (TUI). Always use `--robot` or `--json`.\n\n### Examples\n\n```bash\ncass health\ncass search \"async runtime\" --robot --limit 5\ncass view /path/to/session.jsonl -n 42 --json\ncass expand /path/to/session.jsonl -n 42 -C 3 --json\ncass capabilities --json\ncass robot-docs guide\n```\n\n### Tips\n\n- Use `--fields minimal` for lean output\n- Filter by agent with `--agent`\n- Use `--days N` to limit to recent history\n- Use `--robot-meta` to see requested vs realized search mode, semantic refinement, and lexical fallback reasons\n\nstdout is data-only, stderr is diagnostics; exit code 0 means success.\n\nTreat cass as a way to avoid re-solving problems other agents already handled.\n\n---\n\nNote for Codex/GPT-5.2:\n\nYou constantly bother me and stop working with concerned questions that look similar to this:\n\n```\nUnexpected changes (need guidance)\n\n- Working tree still shows edits I did not make in Cargo.toml, Cargo.lock, src/main.rs, src/patterns.rs. Please advise whether to keep/commit/revert these before any further work. I did not touch them.\n\nNext steps (pick one)\n\n1. Decide how to handle the unrelated modified files above so we can resume cleanly.\n```\n\nNEVER EVER DO THAT AGAIN. The answer is literally ALWAYS the same: those are changes created by the potentially dozen of other agents working on the project at the same time. This is not only a common occurrence, it happens multiple times PER MINUTE. The way to deal with it is simple: you NEVER, under ANY CIRCUMSTANCE, stash, revert, overwrite, or otherwise disturb in ANY way the work of other agents. Just treat those changes identically to changes that you yourself made. Just fool yourself into thinking YOU made the changes and simply don't recall it for some reason.\n\n---\n\n## Note on Built-in TODO Functionality\n\nAlso, if I ask you to explicitly use your built-in TODO functionality, don't complain about this and say you need to use beads.

    "content": "# Changelog\n\nAll notable changes to **cass** (coding-agent-session-search) are documented here.\n\nFormat: [Keep a Changelog](https://keepachangelog.com/en/1.0.0/) with links to representative commits.\nVersioning: [Semantic Versioning](https://semver.org/spec/v2.0.0.html).\n\nRepository: <https://github.com/Dicklesworthstone/coding_agent_session_search>\n\n> **Releases vs. tags**: [v0.1.64](https://github.com/Dicklesworthstone/coding_agent_session_search/releases/tag/v0.1.64), [v0.2.0](https://github.com/Dicklesworthstone/coding_agent_session_search/releases/tag/v0.2.0)–[v0.2.7](https://github.com/Dicklesworthstone/coding_agent_session_search/releases/tag/v0.2.7), [v0.3.0](https://github.com/Dicklesworthstone/coding_agent_session_search/releases/tag/v0.3.0), and [v0.3.7](https://github.com/Dicklesworthstone/coding_agent_session_search/releases/tag/v0.3.7) have published GitHub Releases with downloadable binaries. All other version numbers below are git tags only (no release artifacts).\n\n---\n\n## [v0.3.7] -- 2026-04-23\n\n**Indexer stall observability + zero-writer deadlock fix.**\n\nCuts a release from current `main` so reporters hitting the [#196](https://github.com/Dicklesworthstone/coding_agent_session_search/issues/196) \"phase:indexing, current:0/N indefinitely\" shape get the new forensic machinery and a credible root-cause candidate.\n\n### Added\n\n- **Stall-detection watchdog for `cass index --json`.** Emits a one-shot `stall_detected` NDJSON event when no forward progress has been observed for `CASS_INDEX_STALL_DETECT_SECS` (default 120s; `0` disables). The event carries an on-disk snapshot — lexical rebuild checkpoint (parsed when ≤64 KiB), Tantivy segment count/bytes, and the index-run lock file — plus a hint with strace/gdb/`/proc/<pid>/stack` snippets so operators hitting the hang can attach a live stack to the issue. Latched once per phase, reset on phase transitions, never cancels the run ([`ae411287`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/ae411287)).\n\n### Fixed\n\n- **Zero-writer connection-manager deadlock.** `FrankenConnectionManager::new` now clamps `max_writers < 1` up to 1 and pre-fills the bounded writer-token channel accordingly. Previously, opening a connection manager with `max_writers: 0` left the writer-token channel empty, so the first writer acquisition blocked forever against an empty semaphore. Candidate root cause for [#196](https://github.com/Dicklesworthstone/coding_agent_session_search/issues/196) ([`fd3196fb`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/fd3196fb)).\n- **Indexer lexical manifest**: crash-safe rebuild manifest publish + propagate persistence failures instead of swallowing them ([`6decefa8`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/6decefa8)); sharded rebuild also persists the equivalence ledger and generation manifest ([`75262206`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/75262206)).\n- **Semantic backfill**: warn on NULL `created_at` during semantic backfill instead of silent drift ([`ff156d29`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/ff156d29)).\n- **Search pre-cache**: propagate pre-cache reload failures instead of silently continuing ([`7ec6163f`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/7ec6163f)).\n- **CLI robot output**: `--aggregate` rejects unknown fields as a usage error instead of silently dropping them ([`d3e8dc31`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/d3e8dc31)); `--dry-run` robot output stays reproducible ([`e068eb83`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/e068eb83)).\n\n### Testing\n\n- New proptest coverage for indexer memoization serde round-trips and quarantine summaries ([`a5522d71`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/a5522d71)).\n- Pinned WAL-compaction ordering for small-final resume publish ([`dc0dd881`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/dc0dd881)).\n- Connector and query parser fuzz harnesses added ([`d698f59a`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/d698f59a)).\n\n---\n\n## [v0.3.0](https://github.com/Dicklesworthstone/coding_agent_session_search/releases/tag/v0.3.0) -- 2026-04-12\n\n**GitHub Release** with downloadable binaries.\n\nThis release line focuses on semantic-search concurrency safety, legacy-data correctness, new resume ergonomics, and making the release pipeline fail early instead of cutting broken or partially-updated releases.\n\n### Search and concurrency\n\n- **Semantic search deadlock / TOCTOU hardening**: reduce semantic-search lock scope, add context-token validation across lazy loaders, make two-tier cache availability mode-aware, and add regression coverage for stale-context and cache-poisoning races\n- **Retry storm mitigation**: replace deterministic SQLite retry sleeps with shared jittered exponential backoff for `Busy`, `BusySnapshot`, and related write-conflict paths\n- **Stale lock recovery**: reap dead-owner `index-run.lock` metadata on read so stale lock files stop wedging search and health flows\n- **Query correctness**: NFC-normalize queries and harden empty-index health/status detection\n\n### CLI, data quality, and indexing\n\n- **`cass resume`**: add a CLI subcommand that resolves a session path into a ready-to-run harness resume command, then harden it with UUID validation, false-positive guards, and structured diagnostics\n- **Legacy NULL-agent correctness**: fix search, UI, export, stats, context loading, salvage, and related-session paths that previously dropped or crashed on rows with `NULL agent_id`\n- **Indexer / FTS rebuild reliability**: fix large-batch OOMs, zero-row batch aborts, repeated full-rebuild loops, and several frankensqlite materialization-heavy query paths\n\n### Release engineering\n\n- **Release workflow hardening**: require `HOMEBREW_TAP_TOKEN` before cutting a release, clone all sibling path dependencies in every release job, and avoid failing post-release on a missing Homebrew dispatch token\n- **Installer fallback**: stop probing for a non-existent Intel macOS prebuilt and fall back cleanly to source builds instead\n- **Crates publish readiness gate**: validate `cargo package` before attempting `cargo publish` so the workflow warns and skips instead of failing when the current dependency graph is not registry-ready\n\n---\n\n## [v0.2.7](https://github.com/Dicklesworthstone/coding_agent_session_search/releases/tag/v0.2.7) -- 2026-04-05\n\n**GitHub Release** with downloadable binaries.\n\nValidation release focused on proving the 0.2.6 database/indexing repairs hold under end-to-end conditions and shipping the new regression coverage as part of a fully green release gate.\n\n### Test coverage\n\n- **Duplicate `fts_messages` migration repair, end to end**: add a full CLI regression that injects the legacy duplicate-schema corruption, proves stock SQLite clients fail, runs `cass index` to repair the database, and then verifies health, FTS readability, and post-repair incremental indexing/search behavior\n- **Remote `source_id` FK safety across both persistence paths**: add detailed serial and `BEGIN CONCURRENT` regressions that prove unknown non-`local` sources are auto-registered exactly once, preserve provenance, and keep `foreign_key_check` clean\n- **Incremental watch/index stability after `autocommit_retain` shutdown**: add a repeated idle `watch --watch-once` regression that verifies `autocommit_retain` is actually disabled, idle cycles stay healthy, and newly appended content is still ingested correctly\n\n### Release engineering\n\n- Re-run the full release gate through `rch`, including `cargo fmt --check`, full `cargo test`, `cargo check --all-targets`, and `cargo clippy --all-targets -- -D warnings`\n- Harden the remote test gate by moving `TMPDIR` and `CARGO_TARGET_DIR` off `tmpfs` for the full-suite run so release validation is not derailed by worker RAM-disk exhaustion during link steps\n\n---\n\n## [v0.2.6](https://github.com/Dicklesworthstone/coding_agent_session_search/releases/tag/v0.2.6) -- 2026-04-03\n\n**GitHub Release** with downloadable binaries.\n\nStability release focused on hard database failures in the 0.2.5 upgrade path, incremental indexing reliability, and getting the full test suite back to green.\n\n### Bug fixes\n\n- **V14 FTS migration repair**: Fix duplicate `fts_messages` schema rows left behind by older upgrade paths and harden the frankensqlite-owned rebuild/recovery flow so upgraded databases remain readable instead of tripping `malformed database schema (fts_messages)` on open\n- **Incremental source FK guard**: Register non-`local` `source_id` values during batched incremental persistence so watcher-driven indexing no longer crash-loops on `FOREIGN KEY constraint failed`\n- **Incremental writer memory stability**: Disable `autocommit_retain` on supported frankensqlite connections and tighten writer lifecycle behavior to stop the watch/index incremental path from retaining unbounded MVCC snapshots and running out of memory\n- **Readonly/maintenance-state regressions**: Scope maintenance locks to the active database, prefer heartbeat timestamps in fallback metadata, and fix several readonly/write-path regressions that were cascading through UI, export, and search tests\n- **Watch/index correctness**: Harden watch-once semantics, checkpoint refresh behavior, and fixture validity so incremental indexing matches the intended runtime contract\n\n### Test and release engineering\n\n- Reconcile outdated integration expectations with current frankensqlite behavior, including storage migration, watch E2E, pages/search, and robot-mode coverage\n- Fix doctests, clippy regressions, and non-test utility bins so `cargo test`, `cargo check --all-targets`, `cargo clippy --all-targets -- -D warnings`, and `cargo fmt --check` all pass cleanly before release\n\n---\n\n## [v0.2.5](https://github.com/Dicklesworthstone/coding_agent_session_search/releases/tag/v0.2.5) -- 2026-03-28\n\n**GitHub Release** with downloadable binaries.\n\nHot-fix release addressing FTS5 regression and release infrastructure issues from v0.2.4.\n\n### Bug fixes\n\n- **FTS5 shadow-table corruption**: Close frankensqlite handle before rusqlite FTS schema mutation to prevent shadow-table corruption ([`fb7f431`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/fb7f4311))\n- **FTS cleanup robustness**: Replace `writable_schema` FTS cleanup with `DROP TABLE` + add duplicate schema regression test ([`437758e`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/437758e9))\n- **Watch-once mtime watermark bypass**: Force `since_ts=None` in watch-once mode so old messages are found regardless of mtime watermarks ([`f66ce17`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/f66ce17e))\n- **Install checksum fallback**: Add `SHA256SUMS` (no `.txt` extension) as checksum fallback for installer verification ([`4aaa07e`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/4aaa07e4))\n- **v0.2.4 Linux x86_64 binary was aarch64** (issue [#140](https://github.com/Dicklesworthstone/coding_agent_session_search/issues/140)): Release workflow now adds a post-build architecture verification step to prevent cross-architecture packaging errors\n\n### Refactoring\n\n- **Unified DB engine**: Remove rusqlite FTS dual-backend; make frankensqlite sole DB engine with targeted watch-once fast

checkpoints and Tantivy updates during bulk imports; add fast schema probe to bypass recovery path

large session tree reconciliation ([`ca94cd2`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/ca94cd23))\n- **Memory-aware autotuning**: Add memory-aware autotuning and per-root state isolation to watch-once batch driver ([`65c3fad`](https://github.com/Dicklesworthstone/coding_agent_session_search/commit/65c3fadc))\n\n---\n\n##

All derived assets (lexical index, semantic vectors, analytics rollups, retention backups) can be rebuilt from SQLite; no derived asset is authoritative.\n- Lexical search is the required fast path. Missing, stale, or incompatible lexical assets are treated as derived-state problems that cass should rebuild from SQLite instead of asking operators to perform routine manual repair.\n- Hybrid is the default search intent. Robot metadata (`--robot --robot-meta`) reports the requested mode, realized mode, semantic refinement status, and any lexical fallback reason when semantic assets are not ready.\n- Semantic assets are opportunistic background enrichment. Lexical-only results are expected during first indexing, semantic catch-up, disabled semantic policy, or unavailable local model/vector files.\n- Semantic model acquisition is **opt-in**: `cass models install` downloads the requested embedder on explicit request; cass never auto-downloads. Three embedders are supported via `--model <name>`: `all-minilm-l6-v2` (alias `minilm`, ~90 MB; the default), `snowflake-arctic-s` (~120 MB), and `nomic-embed` (~270 MB). Air-gapped installs use `--from-file <dir>`. While the chosen model is absent, search silently uses lexical-only and reports `fallback_mode=\"lexical\"` in health/status.\n- `cass health --json` and `cass status --json` are the truth surface for readiness, active rebuilds, and recommended action. Prefer their `recommended_action` over hard-coded repair rituals.\n\n**Lexical publish durability (atomic-swap)**\n- Every lexical publish is an atomic renameat2(RENAME_EXCHANGE) on Linux, or a parked-rename + restore-on-failure dance elsewhere. Readers never see a half-torn index — they see either the old or the new generation, never a mix. See `src/indexer/mod.rs::publish_staged_lexical_index`.\n- The prior-live generation is retained under `<data_dir>/index/.lexical-publish-backups/<dated>/` for a bounded retention window. Default cap is `1` (keep just the most-recent prior generation for one-step rollback); override via the `CASS_LEXICAL_PUBLISH_BACKUP_RETENTION` env var (`0` disables retention entirely, higher N keeps deeper history). Pruning runs after every successful publish and emits structured `tracing::info!` events with `freed_bytes` + `retention_limit` for observability.\n- Crash recovery is automatic: a crash between the atomic swap and the retain-rename is handled by `recover_or_finalize_interrupted_lexical_publish_backup` on the next startup, which moves any orphaned canonical sidecar (`.<name>.publish-in-progress.bak`) into `.lexical-publish-backups/` before the next publish lands.\n\n**Quarantine, GC, and the doctor/diag surface**\n- Corrupt or failed-validation assets are quarantined rather than auto-deleted. `cass diag --json --quarantine` enumerates every quarantined artifact (failed seed bundles, retained publish backups, quarantined lexical generations) with `size_bytes`, `age_seconds`, `safe_to_gc`, and a human-readable `gc_reason`. The `safe_to_gc` flag is **advisory** — it reflects retention policy + cleanup dry-run eligibility and is not wired to any automatic deletion path.\n- `cass doctor --json` surfaces the same quarantine summary plus `checks[]` status for every diagnostic the tool runs. Without `--fix`, doctor is read-only (`auto_fix_applied=false`, `auto_fix_actions=[]`, `issues_fixed=0`); with `--fix` it applies only the repairs whose dry-run plans are proven safe (currently: Track A analytics rebuild, Track B rollup rebuild via `rebuild_token_daily_stats` when the `token_usage` ledger is intact).\n- Lexical generation cleanup uses a dispositions + inspection-required-first policy. Operators running `cass doctor --fix` never have a generation reclaimed silently — every quarantine stays on disk until an explicit `cass models backfill` / `cass index --full --force-rebuild` replaces the source data.\n\n**Schema stability guarantees**\n- The JSON contract surfaces (`capabilities`, `health`, `status`, `diag`, `models status`, `models verify`, `models check-update`, `introspect`, `doctor`, `api-version`, `stats`, `sessions`, `search`) are pinned by golden-file regression tests under `tests/golden/robot/`. A change to any field name, type, or nullability fails the golden test suite and requires a deliberate regeneration pass (`UPDATE_GOLDENS=1 cargo test --test golden_robot_json`).\n- `cass introspect --json`'s `response_schemas` block enumerates every schema in a stable alphabetical order (`BTreeMap`-backed — see bead coding_agent_session_search-8sl73).\n- Error envelopes (`{error: {code, kind, message, hint, retryable}}`) have a fixed shape. `kind` values are kebab-case; branch on `err.kind`, not on the numeric code, for codes ≥ 10 (see the Error Handling section below).\n\n## 📬 Agent Mail Fallback (When MCP Tools Are Not Exposed)\n\nIf your runtime does not expose built-in `mcp-agent-mail` tools (for example, `list_mcp_resources` is empty), you can still coordinate via direct MCP HTTP calls.\n\n### 1) Start the local Agent Mail server\n\n```bash\n~/.local/pipx/venvs/mcp-agent-mail/bin/python -m mcp_agent_mail.cli serve-http --host 127.0.0.1 --port 8765\n```\n\n### 2) Use the Streamable HTTP MCP endpoint (`/mcp`)\n\n```bash\ncurl -sS -X POST http://127.0.0.1:8765/mcp \\\n  -H 'Content-Type: application/json' \\\n  -d '{\"jsonrpc\":\"2.0\",\"id\":\"health\",\"method\":\"tools/call\",\"params\":{\"name\":\"health_check\",\"arguments\":{}}}'\n```\n\n### 3) Minimal coordination flow (project -> agent -> message -> inbox -> ack)\n\n```bash\n# Ensure project\ncurl -sS -X POST http://127.0.0.1:8765/mcp -H 'Content-Type: application/json' -d \\\n'{\"jsonrpc\":\"2.0\",\"id\":\"ensure\",\"method\":\"tools/call\",\"params\":{\"name\":\"ensure_project\",\"arguments\":{\"human_key\":\"/data/projects/coding_agent_session_search\"}}}'\n\n# Register agent\ncurl -sS -X POST http://127.0.0.1:8765/mcp -H 'Content-Type: application/json' -d \\\n'{\"jsonrpc\":\"2.0\",\"id\":\"register\",\"method\":\"tools/call\",\"params\":{\"name\":\"register_agent\",\"arguments\":{\"project_key\":\"/data/projects/coding_agent_session_search\",\"program\":\"codex\",\"model\":\"gpt-5\",\"name\":\"YourAgentName\"}}}'\n\n# Send message\ncurl -sS -X POST http://127.0.0.1:8765/mcp -H 'Content-Type: application/json' -d \\\n'{\"jsonrpc\":\"2.0\",\"id\":\"send\",\"method\":\"tools/call\",\"params\":{\"name\":\"send_message\",\"arguments\":{\"project_key\":\"/data/projects/coding_agent_session_search\",\"sender_name\":\"YourAgentName\",\"to\":[\"PeerAgent\"],\"subject\":\"[coord] hello\",\"thread_id\":\"coord-2026-02-13\",\"ack_required\":true,\"body_md\":\"Online and starting work.\"}}}'\n\n# Fetch inbox\ncurl -sS -X POST http://127.0.0.1:8765/mcp -H 'Content-Type: application/json' -d \\\n'{\"jsonrpc\":\"2.0\",\"id\":\"inbox\",\"method\":\"tools/call\",\"params\":{\"name\":\"fetch_inbox\",\"arguments\":{\"project_key\":\"/data/projects/coding_agent_session_search\",\"agent_name\":\"YourAgentName\",\"limit\":50,\"include_bodies\":true}}}'\n\n# Acknowledge message id 42\ncurl -sS -X POST http://127.0.0.1:8765/mcp -H 'Content-Type: application/json' -d \\\n'{\"jsonrpc\":\"2.0\",\"id\":\"ack\",\"method\":\"tools/call\",\"params\":{\"name\":\"call_extended_tool\",\"arguments\":{\"tool_name\":\"acknowledge_message\",\"arguments\":{\"project_key\":\"/data/projects/coding_agent_session_search\",\"agent_name\":\"YourAgentName\",\"message_id\":42}}}}'\n```\n\n### Important caveat\n\n`mcp_agent_mail` defaults to `sqlite+aiosqlite:///./storage.sqlite3`. That means the server working directory determines which mailbox database you are using. To avoid \"project not found\" confusion, start the server from the same directory your team expects for mailbox state.\n\n## 📸 Screenshots\n\n<div align=\"center\">\n\n### Search Results Across All Your Agents\n*Three-pane layout with semantic styling: filter bar with pills, results list with color-coded agents and score tiers, and syntax-highlighted detail preview with tab navigation*\n\n<img src=\"screenshots/screenshot_01.webp\" alt=\"Main TUI showing search results across multiple coding agents\" width=\"800\">\n\n---\n\n### Rich Conversation Detail View\n*Full conversation rendering with markdown formatting, code blocks, headers, and structured content*\n\n<img src=\"screenshots/screenshot_02.webp\" alt=\"Detail view showing formatted conversation content\" width=\"800\">\n\n---\n\n### Quick Start & Keyboard Reference\n*Built-in help screen (press `F1` or `?`) with all shortcuts, filters, modes, and navigation tips*\n\n<img src=\"screenshots/screenshot_03.webp\" alt=\"Help screen showing keyboard shortcuts and features\" width=\"500\">\n\n</div>\n\n---\n\n## 💡 Why This Exists\n\n### The Problem\n\nAI coding agents are transforming how we write software. Claude Code, Codex, Cursor, Copilot, Aider, Pi-Agent; each creates a trail of conversations, debugging sessions, and problem-solving attempts. But this wealth of knowledge is **scattered and unsearchable**:\n\n- **Fragmented storage**: Each agent stores data differently—JSONL files, SQLite databases, markdown logs, proprietary JSON formats\n- **No cross-agent visibility**: Solutions discovered in Cursor are invisible when you're using Claude Code\n- **Lost context**: That brilliant debugging session from two weeks ago? Good luck finding it by scrolling through files\n- **No semantic search by default**: File-based grep doesn't understand natural language queries; cass can add optional local ML search when model files are installed\n\n### The Solution\n\n`cass` treats your coding agent history as a **unified knowledge base**. It:\n\n1. **Normalizes** disparate formats into a common schema\n2. **Indexes** everything with a purpose-built full-text search engine\n3. **Surfaces** relevant past conversations in milliseconds\n4. **Respects** your privacy—everything stays local, nothing phones home\n\n### Who Benefits\n\n- **Individual developers**: Find that solution you know you've seen before\n- **Teams**: Share institutional knowledge across different tool preferences\n- **AI agents themselves**: Let your current agent learn from all your past agents (via robot mode)\n- **Power users**: Build workflows that leverage your complete coding history\n\n---\n\n## ✨ Key Features\n\n### ⚡ Instant Search (Sub-60ms Latency)\n- **\"Search-as-you-type\"**: Results update instantly with every keystroke.\n- **Edge N-Gram Indexing**: We frontload the work by pre-computing prefix matches (e.g., \"cal\" -> \"calculate\") during indexing, trading disk space for O(1) lookup speed at query time.\n- **Smart Tokenization**: Handles `snake_case` (\"my_var\" matches \"my\" and \"var\"), hyphenated terms, and code symbols (`c++`, `foo.bar`) correctly.\n- **Zero-Stall Updates**: The background indexer commits changes atomically; `reader.reload()` ensures new messages appear in the search bar immediately without restarting.\n\n### 🧠 Optional Semantic Search (Local Inference, No Network at Query Time)\n- **Local inference**: Uses a FastEmbed embedder running ONNX on-device. Once the chosen model is installed, no network traffic is required to answer queries.\n- **Opt-in acquisition**: `cass models install` downloads the requested embedder from Hugging Face on explicit request and verifies SHA256 checksums. Nothing is fetched until you run the install command. Three embedders are supported:\n  - `all-minilm-l6-v2` — `cass models install --model all-minilm-l6-v2` (alias: `minilm`). 384-dim. ~90 MB. The default; fastest. Best for general English semantic similarity.\n  - `snowflake-arctic-s` — `cass models install --model snowflake-arctic-s`. 384-dim. ~120 MB. Stronger MTEB scores than MiniLM at similar cost; good drop-in replacement for code-heavy corpora.\n  - `nomic-embed` — `cass models install --model nomic-embed` (alias: `nomic-embed-text-v1.5`). 768-dim. ~270 MB. Highest recall on long-context queries; trade off larger index footprint.\n\n  Removal mirrors install: `cass models remove --model <name>` accepts the same alias set. The same alias map is honored by the daemon embedding worker (see `src/daemon/worker.rs::resolve_embedder_kind`) so background indexing accepts whatever the operator installed.\n\n- **Air-gapped install**: `cass models install --model <name> --from-file <dir>` accepts a pre-downloaded model directory so you can bring the assets in yourself.\n- **Required files** (all must be present after install; `cass models verify` checks them):\n  - `model.onnx`\n  - `tokenizer.json`\n  - `config.json`\n  - `special_tokens_map.json`\n  - `tokenizer_config.json`\n- **Vector index**: Stored as `vector_index/index-<embedder>.fsvi` in the data directory.\n- **Lexical fail-open**: While the model is absent, `cass` returns lexical-only results and reports `fallback_mode=\"lexical\"` in health/status; search never blocks on semantic assets.\n\n#### Hash Embedder Fallback\n\nWhen ML model files are not installed, `cass` uses a deterministic hash-based embedder as a fallback. While not \"truly\" semantic (it captures lexical overlap rather than meaning), it provides useful functionality:\n\n| Feature | ML Model (MiniLM) | Hash Embedder (FNV-1a) |\n|---------|-------------------|------------------------|\n| **Meaning Understanding** | ✅ \"car\" ≈ \"automobile\" | ❌ Exact tokens only |\n| **Initialization Time** | ~500ms (model loading) | <1ms (instant) |\n| **Network Dependency** | None (after install) | None |\n| **Disk Footprint** | ~90MB model files | 0 bytes |\n| **Deterministic** | ✅ Same input = same output | ✅ Same input = same output |\n\n**Algorithm**:\n1. **Tokenize**: Lowercase, split on non-alphanumeric, filter tokens <2 characters\n2. **Hash**: Apply FNV-1a to each token\n3. **Project**: Use hash to determine dimension index and sign (+1 or -1) in a 384-dimensional vector\n4. **Normalize**: L2 normalize to unit length for cosine similarity\n\n**When to Use**:\n- Quick setup without downloading model files\n- Environments where ML inference overhead is unwanted\n- Fallback when ML model fails to load\n\n**Override**: Set `CASS_SEMANTIC_EMBEDDER=hash` to force hash mode even when ML model is available.\n\n#### FSVI Vector Index Format\n\n`cass` uses the **frankensearch FSVI** vector index format (`.fsvi`) for storing semantic embeddings.\n\n**Features**:\n- **Memory-mappable**: large indexes open without copying into RAM\n- **Quantization**: supports `f32` and `f16` storage for smaller on-disk size\n- **Fast search**: brute-force vector search and optional HNSW approximate search\n\n**Index Location**: `~/.local/share/coding-agent-search/vector_index/index-<embedder>.fsvi`\n\n#### Search Modes\n\n`cass` supports three search modes, selectable via `--mode` flag or `Alt+S` in the TUI:\n\n| Mode | Algorithm | Best For |\n|------|-----------|----------|\n| **Lexical** | BM25 full-text | Exact term matching, code searches |\n| **Semantic** | Vector similarity | Conceptual queries, \"find similar\" |\n| **Hybrid** (default) | Reciprocal Rank Fusion with lexical fail-open | Balanced precision and recall |\n\n**Lexical Search**: Uses Tantivy's BM25 implementation with edge n-grams for prefix matching. Best when you know the exact terms you're looking for. The lexical index is derived from SQLite; if it is missing, stale, or incompatible, cass reports the state and rebuilds through the normal indexing path from the canonical database.\n\n**Semantic Search**: Computes vector similarity between query and indexed message embeddings. Finds conceptually related content even without exact term overlap. Requires either the ML model (MiniLM) or falls back to hash embedder.\n\n**Hybrid Search**: The default. It combines lexical and semantic results using Reciprocal Rank Fusion (RRF) when semantic assets are ready, and it fails open to lexical when semantic enrichment is still catching up or disabled:\n```\nRRF_score = Σ 1 / (K + rank_i)\n```\nWhere K=60 (tuning constant) and rank_i is the position in each result list. This balances the precision of lexical search with the recall of semantic search.\n\n```bash\n# CLI examples\ncass search \"authentication\" --mode lexical --robot\ncass search \"how to handle user login\" --mode semantic --robot\ncass search \"auth error handling\" --mode hybrid --robot\n```\n\n### 🎯 Advanced Search Features\n- **Wildcard Patterns**: Full glob-style pattern support:\n  - `foo*` - Prefix match (finds \"foobar\", \"foo123\")\n  - `*foo` - Suffix match (finds \"barfoo\", \"configfoo\")\n  - `*foo*` - Substring match (finds \"afoob\", \"configuration\")\n- **Auto-Fuzzy Fallback**: When exact searches return sparse results, automatically retries with `*term*` wildcards to broaden matches. Visual indicator shows when fallback is active.\n- **Query History Deduplication**: Recent searches deduplicated to show unique queries; navigate with `Up`/`Down` arrows.\n- **Match Quality Ranking**: New ranking mode (cycle with `F12`) that prioritizes exact matches over wildcard/fuzzy results.\n- **Match Highlighting**: Use `--highlight` in robot mode to wrap matching terms with markers (`**bold**` for text, `<mark>` for HTML output).\n\n### 🖥️ Rich Terminal UI (TUI)\n\nPowered by [FrankenTUI (ftui)](https://github.com/Dicklesworthstone/frankentui) — a high-performance Elm-architecture TUI framework with adaptive frame budgets, Bayesian diff selection, and spring-based animations.\n\n- **Three-Pane Layout**: Filter bar (top), scrollable results (left), and syntax-highlighted details (right).\n- **Multi-Line Result Display**: Each result shows location and up to 3 lines of context; alternating stripes improve scanability.\n- **Live Status**: Footer shows real-time indexing progress—agent discovery count during scanning, then item progress with sparkline visualization (e.g., `📦 Indexing 150/2000 (7%) ▁▂▄▆█`)—plus active filters.\n- **Multi-Open Queue**: Queue multiple results with `Ctrl+Enter`, then open all in your editor with `Ctrl+O`. Confirmation prompt for large batches (≥12 items).\n- **Find-in-Detail**: Press `/` to search within the detail pane; matches highlighted with `n`/`N` navigation.\n- **Mouse Support**: Click to select results, scroll panes, or clear filters.\n- **Theming**: Adaptive Dark/Light modes with role-colored messages (User/Assistant/System). Presets include dark, light, high-contrast, and accessible variants.\n- **Ranking Modes**: Cycle through `recent`/`balanced`/`relevance`/`quality` with `F12`; quality mode penalizes fuzzy matches.\n- **Analytics Dashboard**: 7 views (Dashboard, Explorer, Heatmap, Breakdowns, Tools, Plans, Coverage) with interactive charts, KPI tiles, and drill-down filtering. Toggle with `A`.\n- **Inline Mode**: Run `cass tui --inline` to keep terminal scrollback intact. The UI anchors to a region of the terminal while logs scroll normally. Configure with `--ui-height <rows>` and `--anchor top|bottom`.\n- **Macro Recording**: Capture input sessions with `cass tui --record-macro session.macro` for reproducible bug reports and workflow automation. Events are saved as human-readable JSONL with full timing data.\n- **Asciicast Recording**: Capture reproducible TUI demos and bug repro artifacts with `cass tui --asciicast demo.cast`.\n  - Security default: recording captures terminal output only (input keystrokes are not serialized by default).\n\n### 📄 HTML Session Export\n\nExport conversations as styled, portable HTML files with optional encryption:\n\n- **Mostly Self-Contained**: Critical structural CSS and the export payload are inlined directly; the file opens without a local web server. Tailwind's utility CSS runtime (`@tailwindcss/browser`) and Prism.js syntax-highlighting assets are loaded from `cdn.jsdelivr.net` for full fidelity.\n- **Progressive Enhancement / Graceful Degradation**: Prism.js resources fall back via `onerror=\"...no-prism\"` — code blocks remain readable offline in plain monospace.

Resume with `--resume`.\n\n#### Remote Installation Methods\n\nWhen the wizard installs `cass` on remote machines, it uses an intelligent fallback chain:\n\n| Priority | Method | Speed | Requirements |\n|----------|--------|-------|--------------|\n| 1 | **cargo-binstall** | ~30s | `cargo-binstall` pre-installed |\n| 2 | **Pre-built binary** | ~10s | curl/wget, GitHub access |\n| 3 | **cargo install** | ~5min | Rust toolchain, 2GB disk |\n| 4 | **Full bootstrap** | ~10min | curl/wget only (installs rustup) |\n\n**Resource Requirements**:\n- Minimum 2GB disk space\n- Recommended 1GB RAM for compilation\n- SSH access with key-based authentication\n\n**What Gets Installed**:\n- The `cass` binary (location depends on method: `~/.cargo/bin/cass` for cargo-based, `~/.local/bin/cass` for pre-built binary)\n- No daemon, no background services—just the binary\n\n**Installation Progress**: The wizard shows real-time progress for each stage:\n```\nInstalling cass on laptop...\n  [1/4] Checking environment...     ✓\n  [2/4] Downloading binary...       ████████░░ 80%\n  [3/4] Verifying checksum...       ✓\n  [4/4] Setting up PATH...          ✓\n```\n\nUse `--skip-install` if you prefer to install manually on remotes.\n\n#### Host Discovery & Probing\n\nThe setup wizard automatically discovers SSH hosts from your configuration:\n\n**Discovery Sources**:\n- `~/.ssh/config` (parses Host entries)\n- Hosts with wildcards (`*`, `?`) are automatically excluded\n\n**Probe Results** (for each discovered host):\n| Check | Purpose |\n|-------|---------|\n| **Connectivity** | Can we establish SSH connection? |\n| **cass Version** | Is cass already installed? What version? |\n| **Agent Data** | Which agents have session data? |\n| **Session Count** | How many conversations exist? |\n| **System Info** | OS, architecture, disk space, memory |\n\n**Probe Caching**: Results are cached for 5 minutes to speed up repeated setup attempts. Cache clears automatically on expiry.\n\n#### Manual Setup\n\nFor manual configuration without the wizard:\n\n```bash\n# Add a remote machine using platform presets\ncass sources add user@laptop.local --preset macos-defaults\n\n# Or specify paths explicitly\ncass sources add dev@workstation --path ~/.claude/projects --path ~/.codex/sessions\n\n# Sync sessions from all configured sources\ncass sources sync\n\n# Check source health and connectivity\ncass sources doctor\n```\n\n#### Configuration File\n\nSources are configured in the platform config directory (Linux: `~/.config/cass/sources.toml`, macOS: `~/Library/Application Support/cass/sources.toml`):\n\n```toml\n[[sources]]\nname = \"laptop\"\ntype = \"ssh\"\nhost = \"user@laptop.local\"\npaths = [\"~/.claude/projects\", \"~/.codex/sessions\"]\nsync_schedule = \"manual\"\n\n[[sources]]\nname = \"workstation\"\ntype = \"ssh\"\nhost = \"dev@work.example.com\"\npaths = [\"~/.claude/projects\"]\nsync_schedule = \"daily\"\n\n# Path mappings rewrite remote paths to local equivalents\n[[sources.path_mappings]]\nfrom = \"/home/dev/projects\"\nto = \"/Users/me/projects\"\n\n# Agent-specific mappings\n[[sources.path_mappings]]\nfrom = \"/opt/work\"\nto = \"/Volumes/Work\"\nagents = [\"claude_code\"]\n```\n\n**Configuration Fields:**\n| Field | Description |\n|-------|-------------|\n| `name` | Friendly identifier (becomes `source_id`) |\n| `type` | Connection type: `ssh` or `local` |\n| `host` | SSH host (`user@hostname`) |\n| `paths` | Paths to sync (supports `~` expansion) |\n| `sync_schedule` | `manual`, `hourly`, or `daily` |\n| `path_mappings` | Rewrite remote paths to local equivalents |\n\n#### CLI Commands\n\n```bash\n# List configured sources\ncass sources list [--verbose] [--json]\n\n# Add a new source\ncass sources add <user@host> [--name <name>] [--preset macos-defaults|linux-defaults] [--path <path>...] [--no-test]\n\n# Remove a source\ncass sources remove <name> [--purge] [-y]\n\n# Check connectivity and config\ncass sources doctor [--source <name>] [--json]\n\n# Sync sessions\ncass sources sync [--source <name>] [--no-index] [--verbose] [--dry-run] [--json]\n```\n\n#### Excluding Noisy Agent Harnesses\n\nIf one harness is generating mostly junk or looped output, you can disable it persistently even if its files remain on disk:\n\n```bash\n# Inspect current include/exclude state\ncass sources agents list --json\n\n# Stop indexing this harness in future runs\ncass sources agents exclude openclaw\n\n# Re-enable it later\ncass sources agents include openclaw\n```\n\n`cass` stores this preference in `sources.toml` (`~/.config/cass/sources.toml` on Linux, `~/Library/Application Support/cass/sources.toml` on macOS), so future scans, syncs, and watch-mode updates remember it automatically.\n\nBy default, `cass sources agents exclude <agent>` also removes already archived local data for that agent and rebuilds the lexical index so the exclusion frees space instead of only blocking future imports.\n\nIf you want to block future indexing but keep the data already archived:\n\n```bash\ncass sources agents exclude openclaw --keep-indexed-data\n```\n\n#### Sync Engine Internals\n\nThe sync engine uses rsync over SSH for efficient delta transfers, with automatic SFTP fallback:\n\n**Transfer Methods** (auto-detected):\n| Method | When Used | Characteristics |\n|--------|-----------|-----------------|\n| **rsync** | rsync available on both ends | Delta transfers, compression, progress stats |\n| **SFTP** | rsync unavailable | Full file transfers via SSH native protocol |\n\n**Safety Guarantees**:\n- **Additive-only syncs**: rsync runs WITHOUT `--delete` flag—remote deletions never propagate locally\n- **No overwrite risk**: Existing local files are only updated if remote is newer\n- **Atomic operations**: Failed transfers don't leave partial files\n\n**Transfer Configuration**:\n| Setting | Default | Purpose |\n|---------|---------|---------|\n| Connection timeout | 10s | Fail fast on unreachable hosts |\n| Transfer timeout | 5 min | Allow large initial syncs |\n| Compression | Enabled | Reduce bandwidth for text-heavy sessions |\n| Partial transfers | Enabled | Resume interrupted syncs |\n\n**rsync Flags Used**:\n```\n-avz --stats --partial --protect-args --timeout=300 \\\n  -e \"ssh -o BatchMode=yes -o ConnectTimeout=10 -o StrictHostKeyChecking=accept-new\"\n```\nWhere `-avz` = archive mode + verbose + compression.\n\n**Data Flow**:\n```\nRemote: ~/.claude/projects/\n    ↓ (rsync over SSH)\nLocal: ~/.local/share/coding-agent-search/remotes/<source>/<path>/\n    ↓ (connector scan)\nIndex: agent_search.db + tantivy_index/\n```\n\nWhere `<path>` is a filesystem-safe version of the remote path (e.g., `.claude_projects`).\n\nSessions from remotes are indexed alongside local sessions, with provenance tracking to identify origin.\n\n#### Path Mappings\n\nWhen viewing sessions from remote machines, workspace paths may not exist locally. Path mappings rewrite these paths so file links work on your local machine:\n\n```bash\n# List current mappings\ncass sources mappings list laptop\n\n# Add a mapping\ncass sources mappings add laptop --from /home/user/projects --to /Users/me/projects\n\n# Test how a path would be rewritten\ncass sources mappings test laptop /home/user/projects/myapp/src/main.rs\n# Output: /Users/me/projects/myapp/src/main.rs\n\n# Agent-specific mappings (only apply for certain agents)\ncass sources mappings add laptop --from /opt/work --to /Volumes/Work --agents claude_code,codex\n\n# Remove a mapping by index\ncass sources mappings remove laptop 0\n```\n\n#### TUI Source Filtering\n\nIn the TUI, filter sessions by origin:\n- **F11**: Cycle source filter (all → local → remote → all)\n- **Shift+F11**: Open source filter menu to select specific sources\n\nRemote sessions display with a source indicator (e.g., `[laptop]`) in the results list.\n\n#### Provenance Tracking\n\nEach conversation tracks its origin:\n- `source_id`: Machine identifier (e.g., \"laptop\", \"workstation\")\n- `source_kind`: `local` or `remote`\n- `workspace_original`: Original path on the remote machine (before path mapping)\n\nThese fields appear in JSON/robot output and enable filtering:\n```bash\ncass search \"auth error\" --source laptop --json\ncass timeline --days 7 --source remote\ncass stats --by-source\n```\n\n## 🤖 AI / Automation Mode\n\n`cass` is purpose-built for consumption by AI coding agents—not just as an afterthought, but as a first-class design goal. When you're an AI agent working on a codebase, your own session history and those of other agents become an invaluable knowledge base: solutions to similar problems, context about design decisions, debugging approaches that worked, and institutional memory that would otherwise be lost.\n\n### Why Cross-Agent Search Matters\n\nImagine you're Claude Code working on a React authentication bug. With `cass`, you can instantly search across:\n- Your own previous sessions where you solved similar auth issues\n- Codex sessions where someone debugged OAuth flows\n- Cursor conversations about token refresh patterns\n- Aider chats about security best practices\n\nThis cross-pollination of knowledge across different AI agents is transformative. Each agent has different strengths, different context windows, and encounters different problems. `cass` unifies all this collective intelligence into a single, searchable index.\n\n### Self-Documenting API\n\n`cass` teaches agents how to use it—no external documentation required:\n\n```bash\n# Quick capability check: what features exist?\ncass capabilities --json\n# → {\"features\": [\"json_output\", \"cursor_pagination\", \"highlight_matches\", ...], \"connectors\": [...], \"limits\": {...}}\n\n# Full API schema with argument types, defaults, and response shapes\ncass introspect --json\n\n# Topic-based help optimized for LLM consumption\ncass robot-docs commands # All commands and flags\ncass robot-docs schemas # Response JSON schemas\ncass robot-docs examples # Copy-paste invocations\ncass robot-docs exit-codes # Error handling guide\ncass robot-docs guide # Quick-start walkthrough\n```\n\n### Forgiving Syntax (Agent-Friendly Parsing)\n\nAI agents sometimes make syntax mistakes. `cass` aggressively normalizes input to maximize acceptance when intent is clear:\n\n| What you type | What `cass` understands | Correction note |\n|---------------|------------------------|-----------------|\n| `cass -robot --limit=5` | `cass --robot --limit=5` | Single-dash long flags normalized |\n| `cass --Robot --LIMIT 5` | `cass --robot --limit 5` | Case normalized |\n| `cass find \"auth\"` | `cass search \"auth\"` | `find`/`query`/`q` → `search` via alias table |\n| `cass --robot-docs` | `cass robot-docs` | Flag-as-subcommand detected |\n| `cass search --limt 5` | `cass search --limit 5` | Flag typos within Levenshtein distance ≤2 corrected |\n\nThe CLI applies multiple normalization layers:\n1. **Flag typo correction**: Long flag names within Levenshtein distance 2 are auto-corrected (e.g. `--limt` → `--limit`). *Subcommand typos are NOT fuzzy-corrected* — use one of the documented aliases instead (see layer 4 below). A typo that isn't a known alias will produce a clap usage error with the canonical form in the hint.\n2. **Case normalization**: `--Robot`, `--LIMIT` → `--robot`, `--limit`\n3. **Single-dash recovery**: `-robot` → `--robot` (common LLM mistake)\n4. **Subcommand aliases**: `find`/`query`/`q`/`grep`/`lookup` → `search`; `ls`/`list`/`info`/`summary` → `stats`; `st`/`state` → `status`; `reindex`/`idx`/`rebuild` → `index`; `show`/`get`/`read` → `view`; `docs`/`help-robot`/`robotdocs` → `robot-docs`\n5. **Global flag hoisting**: Position-independent flag handling\n\nWhen corrections are applied, `cass` emits a teaching note to stderr so agents learn the canonical syntax.\n\n### Structured Output Formats\n\nEvery command supports machine-readable output:\n\n```bash\n# Pretty-printed JSON (default robot mode)\ncass search \"error\" --robot\n\n# Streaming JSONL: one hit per line. Add --robot-meta to prepend a\n# _meta header line (elapsed_ms, next_cursor, state, index_freshness).\ncass search \"error\" --robot-format jsonl               # hits only\ncass search \"error\" --robot-format jsonl --robot-meta  # 1 _meta header + hits\n\n# Compact single-line JSON (minimal bytes)\ncass search \"error\" --robot-format compact\n\n# Include performance metadata\ncass search \"error\" --robot --robot-meta\n# → { \"hits\": [...], \"_meta\": { \"elapsed_ms\": 12, \"cache_hit\": true, \"wildcard_fallback\": false, ... } }\n```\n\n**Design principle**: stdout contains only parseable JSON data; all diagnostics, warnings, and progress go to stderr.\n\n### Token Budget Management\n\nLLMs have context limits. `cass` provides multiple levers to control output size:\n\n| Flag | Effect |\n|------|--------|\n| `--fields minimal` | Only `source_path`, `line_number`, `agent` |\n| `--fields summary` | Adds `title`, `score` |\n| `--fields score,title,snippet` | Custom field selection |\n| `--max-content-length 500` | Truncate long fields (UTF-8 safe, adds \"...\") |\n| `--max-tokens 2000` | Soft budget (~4 chars/token); adjusts truncation dynamically |\n| `--limit 5` | Cap number of results |\n\nTruncated fields include a `*_truncated: true` indicator so agents know when they're seeing partial content.\n\n### Error Handling for Agents\n\nErrors are structured, actionable, and include recovery hints. A real sample from `cass search foo --robot` against a fresh data dir:\n\n```json\n{\n  \"error\": {\n    \"code\": 3,\n    \"kind\": \"missing-index\",\n    \"message\": \"cass has not been initialized in <data_dir> yet, so search cannot run until the first index completes.\",\n    \"hint\": \"Run 'cass index --full' once to discover local sessions and build the initial archive.\",\n    \"retryable\": true\n  }\n}\n```\n\n**Kind names** are kebab-case (e.g. `missing-index`, `missing-db`, `semantic-unavailable`, `embedder-unavailable`, `ambiguous-source`, `timeout`, `config`, `lock-busy`, `network`). Agents that branch on `err.kind` should treat them as stable identifiers. The full set (~50 kinds as of 0.3.x) is defined in `src/lib.rs`; the canonical way to discover a kind programmatically is to trigger the condition and inspect `err.kind` from the JSON envelope.\n\n**Exit codes** follow a semantic convention:\n| Code | Meaning | Typical action |\n|------|---------|----------------|\n| 0 | Success | Parse stdout |\n| 1 | Health check failed | Run `cass index --full` |\n| 2 | Usage error | Fix syntax (hint provided) |\n| 3 | Index/DB missing | Run `cass index --full` (retryable: true) |\n| 4 | Network error | Check connectivity |\n| 5 | Data corruption | Run `cass index --full --force-rebuild` |\n| 6 | Incompatible version | Update cass |\n| 7 | Lock/busy | Retry later |\n| 8 | Partial result | Increase `--timeout` or reduce scope |\n| 9 | Unknown error | Check `retryable` flag |\n| 10 | Config / timeout | Depends on `err.kind` |\n| 11 | Config validation | Fix config |\n| 12 | Source / SSH | Check remote host |\n| 13 | Mapping / not-found | Depends on `err.kind` |\n| 14 | I/O / mapping | Retry or inspect path |\n| 15 | Semantic / embedder unavailable | Install model or `--mode lexical` |\n| 20-21 | Model acquisition | Check `err.kind`, `err.hint` |\n| 22 | I/O during model handling | Retry |\n| 23 | Model download | Retry or use `--from-file` |\n| 24 | I/O during model verify/install | Retry |\n\n**Codes ≥ 10 are domain-specific** and the numeric value alone is ambiguous (e.g. code 10 maps to either `config` or `timeout` kinds depending on context). Agents should branch on `err.kind` from the JSON error envelope — not on the numeric code — when handling codes ≥ 10. See the Error Handling section above for the canonical `kind` list.\n\nThe `retryable` field tells agents whether a retry might succeed (e.g., transient I/O) vs. guaranteed failure (e.g., invalid path).\n\n### Session Analysis Commands\n\nBeyond search, `cass` provides commands for deep-diving into specific sessions:\n\n```bash\n# Discover the current session for this workspace\ncass sessions --current --json\n\n# List recent sessions for a specific project\ncass sessions --workspace /path/to/project --json --limit 5\n\n# Export full conversation to shareable format\ncass export /path/to/session.jsonl --format markdown -o conversation.md\ncass export /path/to/session.jsonl --format json --include-tools\n\n# Export as self-contained HTML with encryption (recommended for sharing)\ncass export-html /path/to/session.jsonl                     # To Downloads folder\nprintf '%s\\n' \"pwd\" | cass export-html session.jsonl --encrypt --password-stdin\ncass export-html session.jsonl --open --json                # Open in browser, JSON output\n\n# Common agent flow: find current session, then export it\ncass export-html \"$(cass sessions --current --json | jq -r '.sessions[0].path')\" --json\n\n# Expand context around a specific line (from search result)\ncass expand /path/to/session.jsonl -n 42 -C 5 --json\n# → Shows 5 messages before and after line 42\n\n# Activity timeline: when were agents active?\ncass timeline --today --json --group-by hour\ncass timeline --since 7d --agent claude --json\n# → Grouped activity counts, useful for understanding work patterns\n```\n\n### Aggregation & Analytics\n\nAggregate search results server-side to get counts and distributions without transferring full result data:\n\n```bash\n# Count results by agent\ncass search \"error\" --robot --aggregate agent\n# → { \"aggregations\": { \"agent\": { \"buckets\": [{\"key\": \"claude_code\", \"count\": 45}, ...] } } }\n\n# Multi-field aggregation\ncass search \"bug\" --robot --aggregate agent,workspace,date\n\n# Combine with filters\ncass search \"TODO\" --agent claude --robot --aggregate workspace\n```\n\n**Aggregation Fields**:\n| Field | Description |\n|-------|-------------|\n| `agent` | Group by agent type (claude_code, codex, cursor, etc.) |\n| `workspace` | Group by workspace/project path |\n| `date` | Group by date (YYYY-MM-DD) |\n| `match_type` | Group by match quality (exact, prefix, fuzzy) |\n\n**Response Format**:\n```json\n{\n  \"aggregations\": {\n    \"agent\": {\n      \"buckets\": [\n        {\"key\": \"claude_code\", \"count\": 120},\n        {\"key\": \"codex\", \"count\": 85}\n      ],\n      \"other_count\": 15\n    }\n  }\n}\n```\n\nTop 10 buckets are returned per field, with `other_count` for remaining items.\n\n### Chained Search (Pipeline Mode)\n\nChain multiple searches together by piping session paths from one search to another:\n\n```bash\n# Find sessions mentioning \"auth\", then search within those for \"token\"\ncass search \"authentication\" --robot-format sessions | \\\n  cass search \"refresh token\" --sessions-from - --robot\n\n# Build a filtered corpus from today's work\ncass search --today --robot-format sessions > today_sessions.txt\ncass search \"bug fix\" --sessions-from today_sessions.txt --robot\n```\n\n**How It Works**:\n1. First search with `--robot-format sessions` outputs one session path per line\n2. Second search with `--sessions-from <file>` restricts search to those sessions\n3. Use `-` to read from stdin for true piping\n\n**Use Cases**:\n- **Drill-down**: Broad search → narrow within results\n- **Cross-reference**: Find sessions with term A, then find term B within them\n- **Corpus building**: Save session lists for repeated searches\n\n### Match Highlighting\n\nThe `--highlight` flag wraps matching terms for visual/programmatic identification:\n\n```bash\ncass search \"authentication error\" --robot --highlight\n# In text output: **authentication** and **error** are bold-wrapped\n# In HTML export: <mark>authentication</mark> and <mark>error</mark>\n```\n\nHighlighting is query-aware: quoted phrases like `\"auth error\"` highlight as a unit; individual terms highlight separately.\n\n### Pagination & Cursors\n\nFor large result sets, use cursor-based pagination:\n\n```bash\n# First page\ncass search \"TODO\" --robot --robot-meta --limit 20\n# → { \"hits\": [...], \"_meta\": { \"next_cursor\": \"eyJ...\" } }\n\n# Next page\ncass search \"TODO\" --robot --robot-meta --limit 20 --cursor \"eyJ...\"\n```\n\nCursors are opaque tokens encoding the pagination state. They remain valid as long as the index isn't rebuilt.\n\n### Request Correlation\n\nFor debugging and logging, attach a request ID:\n\n```bash\ncass search \"bug\" --robot --request-id \"req-12345\"\n# → { \"hits\": [...], \"_meta\": { \"request_id\": \"req-12345\" } }\n```\n\n### Idempotent Operations\n\nFor safe retries (e.g., in CI pipelines or flaky networks):\n\n```bash\ncass index --full --idempotency-key \"build-$(date +%Y%m%d)\"\n# If same key + params were used in last 24h, returns cached result\n```\n\n### Query Analysis\n\nDebug why a search returned unexpected results:\n\n```bash\ncass search \"auth*\" --robot --explain\n# → Includes parsed query AST, term expansion, cost estimates\n\ncass search \"auth error\" --robot --dry-run\n# → Validates query syntax without executing\n```\n\n### Traceability\n\nFor debugging agent pipelines:\n\n```bash\ncass search \"error\" --robot --trace-file /tmp/cass-trace.json\n# Appends execution span with timing, exit code, and command details\n```\n\n### Search Flags Reference\n\n| Flag | Purpose |\n|------|---------|\n| `--robot` / `--json` | JSON output (pretty-printed) |\n| `--robot-format jsonl\\|compact` | Streaming or single-line JSON |\n| `--robot-meta` | Include `_meta` block (elapsed_ms, cache stats, index freshness) |\n| `--fields minimal\\|summary\\|<list>` | Reduce payload size |\n| `--max-content-length N` | Truncate content fields to N chars |\n| `--max-tokens N` | Truncate content fields to N chars |\n| `--timeout N` | Timeout in milliseconds; returns partial results on expiry |\n| `--cursor <token>` | Cursor-based pagination (from `_meta.next_cursor`) |\n| `--request-id ID` | Echoed in response for correlation |\n| `--aggregate agent,workspace,date` | Server-side aggregations |\n| `--explain` | Include query analysis (parsed query, cost estimate) |\n| `--dry-run` | Validate query without executing |\n| `--source <source>` | Filter by source: `local`, `remote`, `all`, or specific source ID |\n| `--highlight` | Highlight matching terms in output |\n\n### Index Flags Reference\n\n| Flag | Purpose |\n|------|---------|\n| `--idempotency-key KEY` | Safe retries: same key + params returns cached result (24h TTL) |\n| `--json` | JSON output with stats |\n\n### Robot Documentation System\n\nFor machine-readable documentation, use `cass robot-docs <topic>`:\n\n| Topic | Content |\n|-------|---------|\n| `commands` | Full command reference with all flags |\n| `env` | Environment variables and defaults |\n| `paths` | Data directory locations per platform |\n| `guide` | Quick start guide for automation |\n| `schemas` | JSON response schemas |\n| `exit-codes` | Exit code meanings and retry guidance |\n| `examples` | Copy-paste usage examples |\n| `contracts` | API contract version and stability |\n| `sources` | Remote sources configuration guide |\n\n```bash\n# Get documentation programmatically\ncass robot-docs guide\ncass robot-docs schemas\ncass robot-docs exit-codes\n\n# Machine-first help (wide output, no TUI assumptions)\ncass --robot-help\n```\n\n### API Contract & Versioning\n\n`cass` maintains a stable API contract for automation:\n\n```bash\ncass api-version --json\n# → { \"version\": \"0.4.0\", \"contract_version\": \"1\", \"breaking_changes\": [] }\n\ncass introspect --json\n# → Full schema: all commands, arguments, response types\n```\n\n**Contract Version**: Currently `1`. Increments only on breaking changes.\n\n**Guaranteed Stable**:\n- Exit codes and their meanings\n- JSON response structure for `--robot` output\n- Flag names and behaviors\n- `_meta` block format\n\n### Ready-to-paste blurb for AGENTS.md / CLAUDE.md\n\n```\n🔎 cass — Search All Your Agent History\n\n What: cass indexes conversations from Claude Code, Codex, Cursor, Gemini, Aider, ChatGPT, and more into a unified, searchable index. Before solving a problem from scratch, check if any agent already solved something similar.\n\n ⚠️ NEVER run bare cass — it launches an interactive TUI. Always use --robot or --json.\n\n Quick Start\n\n # Check if index is healthy (exit 0=ok, 1=run index first)\n cass health\n\n # Search across all agent histories\n cass search \"authentication error\" --robot --limit 5\n\n # View a specific result (from search output)\n cass view /path/to/session.jsonl -n 42 --json\n\n # Expand context around a line\n cass expand /path/to/session.jsonl -n 42 -C 3 --json\n\n # Learn the full API\n cass capabilities --json # Feature discovery\n cass robot-docs guide # LLM-optimized docs\n\n Why Use It\n\n - Cross-agent knowledge: Find solutions from Codex when using Claude, or vice versa\n - Forgiving syntax: Typos and wrong flags are auto-corrected with teaching notes\n - Token-efficient: --fields minimal returns only essential data\n\n Key Flags\n\n | Flag | Purpose |\n |------------------|--------------------------------------------------------|\n | --robot / --json | Machine-readable JSON output (required!) |\n | --fields minimal | Reduce payload: source_path, line_number, agent only |\n | --limit N | Cap result count |\n | --agent NAME | Filter to specific agent (claude, codex, cursor, etc.) |\n | --days N | Limit to recent N days |\n\n stdout = data only, stderr = diagnostics. Exit 0 = success.\n```\n\n---\n\n## 🔤 Query Language Reference\n\n`cass` supports a rich query syntax designed for both humans and machines.\n\n### Basic Queries\n\n| Query | Matches |\n|-------|---------|\n| `error` | Messages containing \"error\" (case-insensitive) |\n| `python error` | Messages containing both \"python\" AND \"error\" |\n| `\"authentication failed\"` | Exact phrase match |\n| `auth fail` | Both terms, in any order |\n\n### Boolean Operators\n\nCombine terms with explicit operators for complex queries:\n\n| Operator | Example | Meaning |\n|----------|---------|---------|\n| `AND` | `python AND error` | Both terms required (default) |\n| `OR` | `error OR warning` | Either term matches |\n| `NOT` | `error NOT test` | First term, excluding second |\n| `-` | `error -test` | Shorthand for NOT |\n\n**Operator Precedence**: NOT binds tightest, then AND, then OR. Use parentheses (in robot mode) for explicit grouping.\n\n```bash\n# Complex boolean query\ncass search \"authentication AND (error OR failure) NOT test\" --robot\n\n# Exclude test files\ncass search \"bug fix -test -spec\" --robot\n\n# Either error type\ncass search \"TypeError OR ValueError\" --robot\n```\n\n### Phrase Queries\n\nWrap terms in double quotes for exact phrase matching:\n\n| Query | Matches |\n|-------|---------|\n| `\"file not found\"` | Exact sequence \"file not found\" |\n| `\"cannot read property\"` | Exact JavaScript error message |\n| `\"def test_\"` | Function definitions starting with test_ |\n\nPhrases respect word order and proximity. Useful for error messages, code patterns, and specific terminology.\n\n### Wildcard Patterns\n\n| Pattern | Type | Matches | Performance |\n|---------|------|---------|-------------|\n| `auth*` | Prefix | \"auth\", \"authentication\", \"authorize\" | Fast (uses edge n-grams) |\n| `*tion` | Suffix | \"authentication\", \"function\", \"exception\" | Slower (regex scan) |\n| `*config*` | Substring | \"reconfigure\", \"config.json\", \"misconfigured\" | Slowest (full regex) |\n| `test_*` | Prefix | \"test_user\", \"test_auth\", \"test_helpers\" | Fast |\n\n**Tip**: Prefix wildcards (`foo*`) are optimized via pre-computed edge n-grams. Suffix and substring wildcards fall back to regex and are slower on large indexes.\n\n### Query Modifiers\n\n```bash\n# Field-specific search (in robot mode)\ncass search \"error\" --agent claude --workspace /path/to/project\n\n# Time-bounded search\ncass search \"bug\" --since 2024-01-01 --until 2024-01-31\ncass search \"bug\" --today\ncass search \"bug\" --days 7\n\n# Combined filters\ncass search \"authentication\" --agent codex --workspace myproject --week\n```\n\n### Flexible Time Input\n\n`cass` accepts a wide variety of time/date formats for filtering:\n\n| Format | Examples | Description |\n|--------|----------|-------------|\n| **Relative** | `-7d`, `-24h`, `-30m`, `-1w` | Days, hours, minutes, weeks ago |\n| **Keywords** | `now`, `today`, `yesterday` | Named reference points |\n| **ISO 8601** | `2024-11-25`, `2024-11-25T14:30:00Z` | Standard datetime |\n| **US Dates** | `11/25/2024`, `11-25-2024` | Month/Day/Year |\n| **Unix Timestamp** | `1732579200` | Seconds since epoch |\n| **Unix Millis** | `1732579200000` | Milliseconds (auto-detected) |\n\n**Intelligent Heuristics**:\n- Numbers >10 digits are treated as milliseconds, otherwise seconds\n- Two-digit years are expanded (24 → 2024)\n- Date-only inputs default to midnight start or 23:59:59 end\n\n```bash\n# All equivalent for \"last week\"\ncass search \"bug\" --since -7d\ncass search \"bug\" --since \"-1w\"\ncass search \"bug\" --days 7\n\n# Date range\ncass search \"feature\" --since 2024-01-01 --until 2024-01-31\n\n# Mix formats\ncass search \"error\" --since yesterday --until now\n```\n\n### Match Types\n\nSearch results include a `match_type` indicator:\n\n| Type | Meaning | Score Boost |\n|------|---------|-------------|\n| `exact` | Query terms found verbatim | Highest |\n| `prefix` | Matched via prefix expansion (e.g., `auth*`) | High |\n| `suffix` | Matched via suffix pattern | Medium |\n| `substring` | Matched via substring pattern | Lower |\n| `fuzzy` | Auto-fallback match when exact results sparse | Lowest |\n\n### Auto-Fuzzy Fallback\n\nWhen an exact query returns fewer than 3 results, `cass` automatically retries with wildcard expansion:\n- `auth` → `*auth*`\n- Results are flagged with `wildcard_fallback: true` in robot mode\n- TUI shows a \"fuzzy\" indicator in the status bar\n\n---\n\n## ⌨️ Complete Keyboard Reference\n\n### Global Keys\n\n| Key | Action |\n|-----|--------|\n| `Ctrl+C` | Quit |\n| `F1` or `?` | Toggle help screen |\n| `F2` | Toggle dark/light theme |\n| `Ctrl+B` | Toggle border style (rounded/plain) |\n| `Ctrl+Shift+R` | Force re-index |\n| `Ctrl+Shift+Del` | Reset all TUI state |\n\n### Search Bar (Query Input)\n\n| Key | Action |\n|-----|--------|\n| Type | Live search as you type |\n| `Enter` | Submit query immediately (if query is empty, edits last filter chip) |\n| `Esc` | Clear query / exit search |\n| `Up`/`Down` | Navigate query history |\n| `Ctrl+R` | Cycle through query history |\n| `Backspace` | Delete character;

Score = `text_relevance × 0.3 + recency × 0.7`\n   - Best for: \"What was I working on?\"\n\n2. **Balanced**: Equal weight to relevance and recency\n   - Score = `text_relevance × 0.5 + recency × 0.5`\n   - Best for: General-purpose search\n\n3. **Relevance**: Prioritizes text match quality\n   - Score = `text_relevance × 0.8 + recency × 0.2`\n   - Best for: \"Find the best explanation of X\"\n\n4. **Match Quality**: Penalizes fuzzy/wildcard matches\n   - Score = `text_relevance × 0.7 + recency × 0.2 + match_exactness × 0.1`\n   - Best for: Precise technical searches\n\n5. **Date Newest**: Pure chronological order (newest first)\n   - Ignores relevance scoring entirely\n   - Best for: \"Show me all recent activity\"\n\n6. **Date Oldest**: Pure reverse chronological order (oldest first)\n   - Ignores relevance scoring entirely\n   - Best for: \"When did I first work on this?\"\n\n### Score Components\n\n- **Text Relevance (BM25)**: Tantivy's implementation of Okapi BM25, considering:\n  - Term frequency in document\n  - Inverse document frequency across corpus\n  - Document length normalization\n\n- **Recency**: Exponential decay from current time\n  - Documents from today: ~1.0\n  - Documents from last week: ~0.7\n  - Documents from last month: ~0.3\n\n- **Match Exactness**: Bonus for exact matches vs wildcards\n  - Exact phrase: 1.0\n  - Prefix match: 0.8\n  - Suffix/Substring: 0.5\n  - Fuzzy fallback: 0.3\n\n### Blended Scoring Formula\n\nThe final score combines all components using mode-specific weights:\n\n```\nFinal_Score = BM25_Score × Match_Quality + α × Recency_Factor\n```\n\n**Alpha (α) by Ranking Mode**:\n| Mode | α Value | Effect |\n|------|---------|--------|\n| Recent Heavy | 1.0 | Recency dominates |\n| Balanced | 0.4 | Moderate recency boost |\n| Relevance Heavy | 0.1 | BM25 dominates |\n| Match Quality | 0.0 | Pure text matching |\n| Date Newest/Oldest | N/A | Pure chronological sort |\n\n**Match Quality Factors**:\n| Match Type | Factor | Applied When |\n|------------|--------|--------------|\n| Exact | 1.0 | `\"exact phrase\"` |\n| Prefix | 0.9 | `auth*` |\n| Suffix | 0.8 | `*tion` |\n| Substring | 0.6 | `*config*` |\n| Implicit Wildcard | 0.4 | Auto-fallback expansion |\n\n**Recency Factor**: `timestamp / max_timestamp` normalized to [0, 1].\n\nThis formula ensures that \"Recent Heavy\" mode (default) surfaces your most recent work, while \"Relevance Heavy\" finds the best explanations regardless of age.\n\n---\n\n## 🔄 The Normalization Pipeline\n\nEach connector transforms agent-specific formats into a unified schema:\n\n```\n┌─────────────────┐     ┌──────────────────┐     ┌─────────────────┐\n│  Agent Files    │ ──▶ │    Connector     │ ──▶ │  Normalized     │\n│  (proprietary)  │     │  (per-agent)     │     │  Conversation   │\n└─────────────────┘     └──────────────────┘     └─────────────────┘\n     JSONL                   detect()                agent_slug\n     SQLite                  scan()                  workspace\n     Markdown                                        messages[]\n     JSON                                            created_at\n```\n\n### Role Normalization\n\nDifferent agents use different role names:\n\n| Agent | Original | Normalized |\n|-------|----------|------------|\n| Claude Code | `human`, `assistant` | `user`, `assistant` |\n| Codex | `user`, `assistant` | `user`, `assistant` |\n| ChatGPT | `user`, `assistant`, `system` | `user`, `assistant`, `system` |\n| Cursor | `user`, `assistant` | `user`, `assistant` |\n| Aider | (markdown headers) | `user`, `assistant` |\n\n### Timestamp Handling\n\nAgents store timestamps inconsistently:\n\n| Format | Example | Handling |\n|--------|---------|----------|\n| Unix milliseconds | `1699900000000` | Direct conversion |\n| Unix seconds | `1699900000` | Multiply by 1000 |\n| ISO 8601 | `2024-01-15T10:30:00Z` | Parse with chrono |\n| Missing | `null` | Use file modification time |\n\n### Content Flattening\n\nTool calls, code blocks, and nested structures are flattened for searchability:\n\n```json\n// Original (Claude Code)\n{\"type\": \"tool_use\", \"name\": \"Read\", \"input\": {\"path\": \"/foo/bar.rs\"}}\n\n// Flattened for indexing\n\"[Tool: Read] path=/foo/bar.rs\"\n```\n\n---\n\n## 🧹 Deduplication Strategy\n\nThe same conversation content can appear multiple times due to:\n- Agent file rewrites\n- Backup files\n- Symlinked directories\n- Re-indexing\n\n### Content-Based Deduplication\n\n`cass` uses a multi-layer deduplication strategy:\n\n1. **Message Hash**: BLAKE3 of `(role + content + timestamp)`\n   - Identical messages in different files are stored once\n\n2. **Conversation Fingerprint**: Hash of first N message hashes\n   - Detects duplicate conversation files\n\n3. **Search-Time Dedup**: Results are deduplicated by content similarity\n   - Even if stored twice, shown once in results\n\n### Noise Filtering\n\nCommon low-value content is filtered from results:\n- Empty messages\n- Pure whitespace\n- System prompts (unless searching for them)\n- Repeated tool acknowledgments\n\n---\n\n## 💼 Use Cases & Workflows\n\n### 1. \"I solved this before...\"\n\n```bash\n# Find past solutions for similar errors\ncass search \"TypeError: Cannot read property\" --days 30\n\n# In TUI: F12 to switch to \"relevance\" mode for best matches\n```\n\n### 2.

contrast |\n| **Nightfox** | Fox-inspired warm dark | Deep violets with orange highlights |\n| **Cyberpunk Aurora** | Neon aurora on obsidian | Showy, high-saturation dark |\n| **Synthwave '84** | Retro neon magenta/cyan | 80s aesthetic, fun demos |\n| **High Contrast** | Maximum readability | Accessibility needs, bright monitors |\n| **Colorblind** | Deuteranopia/protanopia-safe palette | Color-vision-deficient users |\n\n### WCAG Accessibility\n\nAll theme colors are validated against WCAG (Web Content Accessibility Guidelines) contrast requirements:\n\n- **Text on backgrounds**: Minimum 4.5:1 contrast ratio (AA standard)\n- **Large text/headers**: Minimum 3:1 contrast ratio\n- **Interactive elements**: Clear visual distinction from content\n\nThe theming engine calculates relative luminance and contrast ratios at runtime to ensure readability across all color combinations.\n\n### Role-Aware Message Styling\n\nConversation messages are color-coded by role for quick visual parsing:\n\n| Role | Visual Treatment | Purpose |\n|------|------------------|---------|\n| **User** | Blue-tinted background, bold | Your input, easy to scan |\n| **Assistant** | Green-tinted background | AI responses |\n| **System** | Gray/muted background | Context, instructions |\n| **Tool** | Orange-tinted background | Tool calls, file operations |\n\nEach agent type (Claude, Codex, Cursor, etc.) also receives a subtle tint, making multi-agent result lists instantly scannable.\n\n### Adaptive Borders\n\nBorder decorations automatically adapt to terminal width:\n\n| Width | Style | Example |\n|-------|-------|---------|\n| **Narrow** (<80 cols) | Minimal Unicode | `│ content │` |\n| **Normal** (80-120) | Rounded corners | `╭─ content ─╮` |\n| **Wide** (>120) | Full decorations | Double-line headers |\n\nToggle between rounded Unicode and plain ASCII borders with `Ctrl+B`.\n\n---\n\n## 🔖 Bookmark System\n\nSave important search results with notes and tags for later reference.\n\n### Features\n\n- **Persistent storage**: Bookmarks saved to `bookmarks.db` (SQLite)\n- **Notes**: Add annotations explaining why you bookmarked something\n- **Tags**: Organize with comma-separated tags (e.g., \"rust, important, auth\")\n- **Search**: Find bookmarks by title, note, or snippet content\n- **Export/Import**: JSON format for backup and sharing\n\n### Bookmark Structure\n\n```json\n{\n  \"id\": 1,\n  \"title\": \"Auth bug fix discussion\",\n  \"source_path\": \"/path/to/session.jsonl\",\n  \"line_number\": 42,\n  \"agent\": \"claude_code\",\n  \"workspace\": \"/projects/myapp\",\n  \"note\": \"Good explanation of JWT refresh flow\",\n  \"tags\": \"auth, jwt, important\",\n  \"snippet\": \"The token refresh logic should...\"\n}\n```\n\n### Storage Location\n\nBookmarks are stored separately from the main index:\n- Linux: `~/.local/share/coding-agent-search/bookmarks.db`\n- macOS: `~/Library/Application Support/coding-agent-search/bookmarks.db`\n- Windows: `%APPDATA%\\coding-agent-search\\bookmarks.db`\n\n---\n\n## 🔔 Toast Notification System\n\n`cass` uses a non-intrusive toast notification system for transient feedback—operations complete, errors occur, or state changes without modal dialogs interrupting your workflow.\n\n### Notification Types\n\n| Type | Icon | Auto-Dismiss | Use Case |\n|------|------|--------------|----------|\n| **Info** | ℹ️ | 3 seconds | Status updates, tips |\n| **Success** | ✓ | 2 seconds | Operations completed |\n| **Warning** | ⚠ | 4 seconds | Non-critical issues |\n| **Error** | ✗ | 6 seconds | Failures requiring attention |\n\n### Behavior\n\n- **Non-Blocking**: Toasts appear in a corner without stealing focus\n- **Auto-Dismiss**: Each type has an appropriate display duration\n- **Message Coalescing**: Duplicate messages show a count badge instead of stacking\n- **Configurable Position**: Toasts can appear in any corner (default: top-right)\n- **Maximum Visible**: Limited to 3-5 visible toasts to prevent screen clutter\n\n### Visual Design\n\nToasts feature:\n- **Color-coded borders**: Matches notification type (blue/green/yellow/red)\n- **Theme-aware**: Adapts to current dark/light theme\n- **Subtle animation**: Fade in/out for smooth appearance\n\n### Common Toast Messages\n\n| Trigger | Toast |\n|---------|-------|\n| Index rebuild complete | ✓ \"Index rebuilt: 2,500 conversations\" |\n| Export complete | ✓ \"Exported to conversation.md\" |\n| Copy to clipboard | ✓ \"Copied to clipboard\" |\n| Search timeout | ⚠ \"Search timed out, showing partial results\" |\n| Connector error | ✗ \"Failed to scan ChatGPT: encrypted files\" |\n| Update available | ℹ️ \"Version 0.5.0 available\" |\n\n---\n\n## 🏎️ Performance Engineering: Caching & Warming\nTo achieve sub-60ms latency on large datasets, `cass` implements a multi-tier caching strategy in `src/search/query.rs`:\n\n1. **Sharded LRU Cache**: The `prefix_cache` is split into shards (default 256 entries each) to reduce mutex contention during concurrent reads/writes from the async searcher.\n2. **Bloom Filter Pre-checks**: Each cached hit stores a 64-bit Bloom filter mask of its content tokens. When a user types more characters, we check the mask first. If the new token isn't in the mask, we reject the cache entry immediately without a string comparison.\n3. **Predictive Warming**: A background `WarmJob` thread watches the input. When the user pauses typing, it triggers a lightweight \"warm-up\" query against the Tantivy reader to pre-load relevant index segments into the OS page cache.\n\n## 🔌 The Connector Interface (Polymorphism)\nThe system is designed for extensibility via the `Connector` trait (`src/connectors/mod.rs`). This allows `cass` to treat disparate log formats as a uniform stream of events.\n\n```mermaid\nclassDiagram\n class Connector {\n <<interface>>\n +detect() DetectionResult\n +scan(ScanContext) Vec~NormalizedConversation~\n }\n class NormalizedConversation {\n +agent_slug String\n +messages Vec~NormalizedMessage~\n }\n\n Connector <|-- CodexConnector\n Connector <|-- ClineConnector\n Connector <|-- ClaudeCodeConnector\n Connector <|-- GeminiConnector\n Connector <|-- ClawdbotConnector\n Connector <|-- VibeConnector\n Connector <|-- OpenCodeConnector\n Connector <|-- AmpConnector\n Connector <|-- CursorConnector\n Connector <|-- ChatGptConnector\n Connector <|-- AiderConnector\n Connector <|-- PiAgentConnector\n Connector <|-- FactoryConnector\n Connector <|-- CopilotConnector\n Connector <|-- CopilotCliConnector\n Connector <|-- OpenClawConnector\n Connector <|-- CrushConnector\n Connector <|-- KimiConnector\n Connector <|-- QwenConnector\n\n CodexConnector ..> NormalizedConversation : emits\n ClineConnector ..> NormalizedConversation : emits\n ClaudeCodeConnector ..> NormalizedConversation : emits\n GeminiConnector ..> NormalizedConversation : emits\n ClawdbotConnector ..> NormalizedConversation : emits\n VibeConnector ..> NormalizedConversation : emits\n OpenCodeConnector ..> NormalizedConversation : emits\n AmpConnector ..> NormalizedConversation : emits\n CursorConnector ..> NormalizedConversation : emits\n ChatGptConnector ..> NormalizedConversation : emits\n AiderConnector ..> NormalizedConversation : emits\n PiAgentConnector ..> NormalizedConversation : emits\n FactoryConnector ..> NormalizedConversation : emits\n CopilotConnector ..> NormalizedConversation : emits\n CopilotCliConnector ..> NormalizedConversation : emits\n OpenClawConnector ..> NormalizedConversation : emits\n CrushConnector ..> NormalizedConversation : emits\n KimiConnector ..> NormalizedConversation : emits\n QwenConnector ..> NormalizedConversation : emits\n```\n\n- **Polymorphic Scanning**: The indexer runs connector factories in parallel via rayon, creating fresh `Box<dyn Connector>` instances that are unaware of each other's underlying file formats (JSONL, SQLite, specialized JSON).\n- **Resilient Parsing**: Connectors handle legacy formats (e.g., integer vs ISO timestamps) and flatten complex tool-use blocks into searchable text.\n\n---\n\n## 🧠 Architecture & Engineering\n\n`cass` uses frankensqlite as the durable source of truth and frankensearch as a derived speed layer, powered by a suite of integrated \"franken\" libraries.\n\n### The Pipeline\n1. **Discovery**: [franken_agent_detection](https://github.com/Dicklesworthstone/franken_agent_detection) auto-discovers sessions from 19 coding agents (Claude Code, Codex, Cursor, Gemini, Aider, Amp, Cline, OpenCode, ChatGPT, Pi Agent, Copilot, Copilot CLI, OpenClaw, Clawdbot, Vibe, Crush, Kimi, Qwen, Factory).\n2. **Storage (frankensqlite)**: The **Source of Truth**. Data is persisted to a normalized SQLite schema (`messages`, `conversations`, `agents`) via [frankensqlite](https://github.com/Dicklesworthstone/frankensqlite) — a pure-Rust SQLite reimplementation with `BEGIN CONCURRENT` support for MVCC multi-writer transactions.\n3. **Search Index (frankensearch)**: The **Speed Layer**. New messages are incrementally pushed to a unified search index via [frankensearch](https://github.com/Dicklesworthstone/frankensearch) which provides BM25 lexical search, semantic embeddings, RRF fusion, and cross-encoder reranking in a single library.\n * **Fields**: `title`, `content`, `agent`, `workspace`, `created_at`.\n * **Prefix Fields**: `title_prefix` and `content_prefix` use **Index-Time Edge N-Grams** (not stored on disk to save space) for instant prefix matching.\n * **Deduping**: Search results are deduplicated by content hash to remove noise from repeated tool outputs.\n\n```mermaid\nflowchart LR\n classDef pastel fill:#f4f2ff,stroke:#c2b5ff,color:#2e2963;\n classDef pastel2 fill:#e6f7ff,stroke:#9bd5f5,color:#0f3a4d;\n classDef pastel3 fill:#e8fff3,stroke:#9fe3c5,color:#0f3d28;\n classDef pastel4 fill:#fff7e6,stroke:#f2c27f,color:#4d350f;\n classDef pastel5 fill:#ffeef2,stroke:#f5b0c2,color:#4d1f2c;\n\n subgraph Sources[\"Local Sources\"]\n A1[Codex]:::pastel\n A2[Cline]:::pastel\n A3[Gemini]:::pastel\n A4[Claude]:::pastel\n A5[OpenCode]:::pastel\n A6[Amp]:::pastel\n A7[Cursor]:::pastel\n A8[ChatGPT]:::pastel\n A9[Aider]:::pastel\n A10[Pi-Agent]:::pastel\n A11[Factory]:::pastel\n A12[Copilot Chat]:::pastel\n A13[Copilot CLI]:::pastel\n A14[OpenClaw]:::pastel\n A15[Clawdbot]:::pastel\n A16[Vibe]:::pastel\n A17[Crush]:::pastel\n A18[Kimi]:::pastel\n A19[Qwen]:::pastel\n end\n\n subgraph Remote[\"Remote Sources\"]\n R1[\"sources.toml\"]:::pastel\n R2[\"SSH/rsync\\nSync Engine\"]:::pastel2\n R3[\"remotes/\\nSynced Data\"]:::pastel3\n end\n\n subgraph \"Ingestion Layer\"\n C1[\"franken_agent_detection\\nAuto-Discover & Scan\\nNormalize & Dedupe\"]:::pastel2\n end\n\n subgraph \"Storage + Search\"\n S1[\"frankensqlite (WAL)\\nSource of Truth\\nBEGIN CONCURRENT\\nMigrations\"]:::pastel3\n T1[\"frankensearch\\nBM25 + Semantic\\nRRF Fusion\\nReranking\"]:::pastel4\n end\n\n subgraph \"Presentation\"\n U1[\"TUI (FrankenTUI)\\nElm Architecture\\nAnalytics Dashboard\\nAsync Search\"]:::pastel5\n U2[\"CLI / Robot\\nJSON Output\\nAutomation\"]:::pastel5\n end\n\n A1 --> C1\n A2 --> C1\n A3 --> C1\n A4 --> C1\n A5 --> C1\n A6 --> C1\n A7 --> C1\n A8 --> C1\n A9 --> C1\n A10 --> C1\n A11 --> C1\n A12 --> C1\n A13 --> C1\n A14 --> C1\n A15 --> C1\n A16 --> C1\n A17 --> C1\n A18 --> C1\n A19 --> C1\n R1 --> R2\n R2 --> R3\n R3 --> C1\n C1 -->|Persist| S1\n C1 -->|Index| T1\n S1 -.->|Rebuild| T1\n T1 -->|Query| U1\n T1 -->|Query| U2\n```\n\n### Background Indexing & Watch Mode\n- **Non-Blocking**: The indexer runs in a background thread. You can search while it works.\n- **Parallel Discovery**: Connector detection and scanning run in parallel across all CPU cores using rayon, significantly reducing startup time when multiple agents are installed.\n- **Watch Mode**: Uses file system watchers (`notify`) to detect changes in agent logs. When you save a file or an agent replies, `cass` re-indexes just that conversation and refreshes the search view automatically.\n- **Real-Time Progress**: The TUI footer updates in real-time showing discovered agent count and conversation totals with sparkline visualization (e.g., \"📦 Indexing 150/2000 (7%) ▁▂▄▆█\").\n\n## 🔍 Deep Dive: Internals\n\n### The TUI Engine (Elm Architecture on FrankenTUI)\nThe interactive interface (`src/ui/app.rs`) uses **FrankenTUI (ftui)**, a Rust TUI framework implementing the Elm architecture (Model-View-Update). The runtime handles terminal lifecycle, event polling, rendering, and cleanup.\n\n1. **Model (CassApp)**: A monolithic struct tracks the entire UI state (search query, cursor position, scroll offsets, active filters, cached details, animation state).\n2. **Update**: Each event (key, mouse, tick, resize) maps to a `CassMsg` variant. The `update()` function produces `Cmd` effects (async tasks, ticks, quit).\n3. **View**: The `view()` function renders the current state to an ftui `Frame`. The runtime diff engine minimizes terminal writes using Bayesian strategy selection.\n4. **Adaptive Budget**: A 16ms (60fps) frame budget with PID-controlled degradation automatically simplifies rendering (borders, animations) when frame times exceed budget.\n5. **Background Tasks**: Search queries, indexing, and analytics run on background threads via `Cmd::Task`, with results delivered as messages.\n\n```mermaid\ngraph TD\n Input([User Input]) -->|Key/Mouse/Tick| Runtime\n Runtime -->|CassMsg| Update[Model::update]\n Update -->|Cmd| Runtime\n Update -->|State Change| View[Model::view]\n View -->|Frame| DiffEngine[Bayesian Diff]\n DiffEngine -->|Minimal Writes| Terminal\n\n Update -->|Cmd::Task| Background[Background Thread]\n Background -->|Result Msg| Runtime\n```\n\n### Append-Only Storage Strategy\nData integrity is paramount. `cass` treats the SQLite database (`src/storage/sqlite.rs`, powered by frankensqlite) as an **append-only log** for conversations:\n\n- **Immutable History**: When an agent adds a message to a conversation, we don't update the existing row. We insert the new message linked to the conversation ID.\n- **Deduplication**: The connector layer uses content hashing to prevent duplicate messages if an agent re-writes a file.\n- **Versioning**: A `schema_version` meta-table and strict migration path ensure that upgrades (like the recent move to v3) are safe and atomic.\n\n---\n\n## 🛡️ Index Resilience & Recovery\n\n`cass` treats search indexes as derived assets. The SQLite archive is authoritative; lexical and semantic search data can be rebuilt from it.\n\n### Schema Version Tracking\n\nEvery Tantivy index stores a `schema_hash.json` file containing the schema version:\n\n```json\n{\"schema_hash\":\"tantivy-schema-v4-edge-ngram-agent-string\"}\n```\n\n### Automatic Recovery Scenarios\n\n| Scenario | Detection | Recovery |\n|----------|-----------|----------|\n| First run | No SQLite archive and no lexical index | `cass index --full` discovers sessions and creates both |\n| Missing lexical index | No readable lexical asset | Rebuild from SQLite into scratch space, then publish |\n| Schema mismatch | Hash differs from current | Rebuild derived lexical asset from SQLite |\n| Corrupted metadata | Invalid or missing lexical metadata | Ignore the broken derivative and rebuild from SQLite |\n| Semantic not ready | Model/vector assets absent or still backfilling | Continue lexical search and report semantic fallback/readiness |\n\n### Manual Recovery\n\n```bash\n# Check the current truth surface first\ncass health --json\ncass status --json\n\n# If recommended_action asks for it, refresh derived search data\ncass index --full\n```\n\nManual rebuild commands are for first setup, explicit operator refresh, or cases where `recommended_action` asks for them. A normal missing/stale lexical asset should be repaired as derived state from SQLite, not treated as lost user data.\n\n### Design Principles\n\n1. **Never lose source data**: `cass` only reads agent files, never modifies them\n2. **SQLite is the source of truth**: Derived lexical and semantic assets can be rebuilt\n3. **Atomic publish**: Rebuilt assets are prepared in scratch space and published only when complete\n4. **Graceful degradation**: Hybrid search continues as lexical when semantic enrichment is unavailable\n\n### Index Recovery & Self-Healing\n\n`cass` maintains multiple layers of redundancy to recover from corruption or schema changes:\n\n**Schema Hash Versioning**:\nEach Tantivy index stores a `schema_hash.json` file containing a hash of the current schema definition. On startup:\n1. If hash matches → open existing index\n2. If hash differs → schema changed, trigger rebuild\n3. If file missing/corrupted → assume stale, trigger rebuild\n\nThis ensures that version upgrades with schema changes can rebuild the lexical derivative without user intervention.\n\n**Automatic Rebuild Triggers**:\n| Condition | Detection | Action |\n|-----------|-----------|--------|\n| Schema version change | Hash mismatch in `schema_hash.json` | Full rebuild |\n| Missing `meta.json` | Tantivy can't open index | Rebuild and publish a fresh derivative |\n| Corrupted index files | `Index::open_in_dir()` fails | Rebuild and publish a fresh derivative |\n| Explicit request | `--force-rebuild` flag | Clean slate rebuild |\n\n**SQLite as Ground Truth**:\nThe SQLite database serves as the authoritative data store. Lexical rebuilds reconstruct the Tantivy index from SQLite:\n```rust\n// Iterate all conversations from SQLite\n// Re-index each message into fresh Tantivy index\n// Progress tracked via IndexingProgress for UI feedback\n```\n\nThis means corrupted lexical data is a repairable derivative-state problem. Operators should read `cass health --json` or `cass status --json` first, then follow `recommended_action`.\n\n### Database Schema Migrations\n\nThe SQLite database uses versioned schema migrations:\n\n| Version | Changes |\n|---------|---------|\n| v1 | Initial schema: agents, workspaces, conversations, messages, snippets, tags |\n| v2 | Added FTS5 full-text search |\n| v3 | Added source provenance tracking |\n| v4 | Added vector embeddings support |\n| v5 | Current: Added remote sources |\n\n**Migration Process**:\n1. On startup, `cass` checks `schema_version` in the database\n2. If version < current, migrations run automatically\n3. Migrations are incremental and non-destructive\n4. User data (bookmarks, TUI state, sources.toml) is always preserved\n\n**Safe Files** (never deleted during rebuild):\n- `bookmarks.db` - Your saved bookmarks\n- `tui_state.json` - UI preferences\n- `sources.toml` - Remote source configuration\n- `.env` - Environment configuration\n\n**Backup Policy**: Up to 3 backups retained during major rebuilds. Older backups are automatically cleaned.\n\n---\n\n## ⏱️ Watch Mode Internals\n\nThe `--watch` flag enables real-time index updates as agent files change.\n\n### Debouncing Strategy\n\n```\nFile change detected\n       ↓\n[2 second debounce window]  ← Accumulate more changes\n       ↓\n[5 second max wait]         ← Force flush if changes keep coming\n       ↓\nRe-index affected files\n```\n\n- **Debounce**: 2 seconds (wait for burst of changes to settle)\n- **Max wait**: 5 seconds (don't wait forever during continuous activity)\n\n### Path Classification\n\nEach file system event is routed to the appropriate connector:\n\n```\n~/.claude/projects/foo.jsonl  → ClaudeCodeConnector\n~/.codex/sessions/rollout-*.jsonl → CodexConnector\n~/.aider.chat.history.md → AiderConnector\n```\n\n### State Tracking\n\nWatch mode maintains `watch_state.json`:\n\n```json\n{\n  \"last_scan_ts\": 1699900000000,\n  \"watched_paths\": [\n    \"~/.claude/projects\",\n    \"~/.codex/sessions\"\n  ]\n}\n```\n\n### Incremental Safety\n\n- **File-level filtering only**: When a file is modified, the entire file is re-scanned\n- **1-second mtime slack**: Accounts for filesystem timestamp granularity\n- **No per-message filtering**: Prevents data loss when new messages are appended\n\n### Codex Token Backfill\n\nCodex `event_msg` `token_count` usage is attached to the nearest preceding assistant turn during indexing.\nIf you indexed Codex sessions before this behavior existed, backfill usage coverage with:\n\n```bash\ncass index --full\ncass analytics rebuild --track a\n```\n\n---\n\n## 🐚 Shell Completions\n\nGenerate tab-completion scripts for your shell.\n\n### Installation\n\n**Bash**:\n```bash\ncass completions bash > ~/.local/share/bash-completion/completions/cass\n# Or: cass completions bash >> ~/.bashrc\n```\n\n**Zsh**:\n```bash\ncass completions zsh > \"${fpath[1]}/_cass\"\n# Or add to ~/.zshrc: eval \"$(cass completions zsh)\"\n```\n\n**Fish**:\n```bash\ncass completions fish > ~/.config/fish/completions/cass.fish\n```\n\n**PowerShell**:\n```powershell\ncass completions powershell >> $PROFILE\n```\n\n### What's Completed\n\n- Subcommands (`search`, `index`, `stats`, etc.)\n- Flags and options (`--robot`, `--agent`, `--limit`)\n- File paths for relevant arguments\n\n---\n\n## System Requirements\n\n- **CPU**: x86_64 processor with **AVX** instruction support (any Intel/AMD CPU from ~2011 onwards). The ONNX Runtime dependency used for semantic search requires AVX instructions. On CPUs without AVX support, the binary will crash with a `SIGILL` (illegal instruction) signal. The `cass` binary includes a runtime check and will print a clear error message if AVX is not detected, but note that ONNX Runtime may be loaded before this check in some code paths.\n- **OS**: Linux, macOS, or Windows\n- **Linux glibc**: Pre-built binaries require **glibc 2.38+** (Ubuntu 24.04+, Fedora 39+, Debian 13+). Ubuntu 20.04 (glibc 2.31) and 22.04 (glibc 2.35) are **not supported** with pre-built binaries. Users on older distributions should build from source with `cargo install --git https://github.com/Dicklesworthstone/coding_agent_session_search`. This requirement exists because CI builds target ubuntu-24.04 to access newer kernel features used by the frankensqlite storage engine.\n- **Disk**: Sufficient space for the search index (varies with session history size)\n\n---\n\n## 🚀 Quickstart\n\n### 1.

Search works immediately (falling back to SQLite or partial results until complete).*\n\n### 3. Usage\n- **Type to search**: \"python error\", \"refactor auth\", \"c++\".\n- **Wildcards**: Use `foo*` (prefix), `*foo` (suffix), or `*foo*` (contains) for flexible matching.\n- **Navigation**: `Up`/`Down` to select, `Right` to focus detail pane. `Up`/`Down` in search bar navigates query history.\n- **Filters**:\n    - `F3`: Filter by Agent (e.g., \"codex\").\n    - `F4`: Filter by Workspace/Project.\n    - `F5`/`F6`: Time filters (Today, Week, etc.).\n- **Modes**:\n    - `F2`: Toggle Dark/Light theme.\n    - `F12`: Cycle ranking mode (recent → balanced → relevance → quality → newest → oldest).\n    - `Ctrl+B`: Toggle rounded/plain borders.\n- **Actions**:\n    - `Enter`: Open selected result in contextual detail modal (defaults to Messages tab).\n    - `Enter` with no selected hit: submit query behavior (no-op if empty).\n    - `F8`: Open selected hit in `$EDITOR`.\n    - `Ctrl+Enter`: Add current result to queue (multi-open).\n    - `Ctrl+O`: Open all queued results in editor.\n    - `Ctrl+M` / `Ctrl+X`: Toggle selection on current item.\n    - `A`: Bulk actions menu (when items selected).\n    - `y`: Copy file path or snippet to clipboard.\n    - `/`: Find text within detail pane; `n`/`N` cycle matches; `Esc` exits find before closing modal.\n    - `Ctrl+Shift+R`: Trigger manual re-index (refresh search results).\n    - `Ctrl+Shift+Del`: Reset TUI state (clear history, filters, layout).\n\n### 4.

there is no separate `cass cast` subcommand |\n| `scripts/bakeoff/cass_validation_e2e.sh` | Run the bake-off validation harness for lexical, semantic, hybrid, and reranked search scenarios |\n| `scripts/bakeoff/cass_embedder_e2e.sh` | Exercise embedder bake-off flows against a generated validation corpus |\n| `scripts/bakeoff/cass_rerank_e2e.sh` | Exercise reranker bake-off flows and append results to the bake-off log |\n\n### Diagnostic Commands\n\nCommands for troubleshooting, debugging, and understanding system state:\n\n```bash\n# Health check (fast, <50ms)\ncass health --json\n# → { \"healthy\": true, \"index_age_seconds\": 120, \"message_count\": 5000 }\n\n# Detailed status with recommendations\ncass status --json\n# → Includes index freshness, staleness threshold, recommended action\n\n# System diagnostics\ncass diag --verbose --json\n# → Database stats, index info, connector status, environment\n\n# Query explanation (debug why results are what they are)\ncass search \"auth\" --explain --dry-run --robot\n# → Shows parsed query, index strategy, cost estimate without executing\n\n# Find related sessions\ncass context /path/to/session.jsonl --json\n# → Sessions from same workspace, same day, or same agent\n\n# Comprehensive diagnostic and repair\ncass doctor --json\n# → Checks data directory, locks, database, index, config files, session sources\n# → Reports issues with severity and recommended fixes\n\n# Auto-fix detected issues (safe - only rebuilds derived data)\ncass doctor --fix\n# → Removes stale locks and rebuilds corrupted derived assets when needed\n\n# Force index rebuild even if healthy\ncass doctor --fix --force-rebuild\n# → Explicit operator refresh from source sessions and SQLite truth\n```\n\n### The Doctor Command\n\n`cass doctor` is a comprehensive diagnostic and repair tool designed for troubleshooting installation and data issues. It follows a strict safety philosophy: **it never deletes user data**.\n\n**What it checks:**\n\n| Check | Description | Auto-Fix Available |\n|-------|-------------|-------------------|\n| `data_directory` | Data dir exists and is writable | ✅ Creates if missing |\n| `lock_file` | No stale indexer locks | ✅ Removes stale locks |\n| `database` | SQLite integrity and accessibility | ✅ Rebuilds if corrupted |\n| `index` | Tantivy index health and schema | ✅ Rebuilds if unhealthy |\n| `config` | Configuration file parsing | ❌ Manual fix required |\n| `sources_config` | sources.toml validity | ❌ Manual fix required |\n| `sessions` | Agent session directories found | ❌ Informational only |\n\n**Safety guarantees:**\n\n- **Never deletes source agent files** - Your Claude, Codex, Cursor sessions are read-only\n- **Never deletes bookmarks** - `bookmarks.db` is preserved\n- **Never deletes UI state** - `tui_state.json` is preserved\n- **Never deletes sources config** - `sources.toml` is preserved\n- **Only rebuilds derived data** - Database and search index can always be regenerated from source sessions\n\n**Example output:**\n\n```bash\n$ cass doctor\n🩺 cass doctor - Installation Diagnostics\n\n✓ data_directory: OK - Data directory exists and is writable\n✓ lock_file: OK - No stale locks found\n✓ database: OK - Database accessible (5,234 messages)\n✗ index: WARN - Index schema outdated (rebuild recommended)\n✓ config: OK - Configuration valid\n✓ sources_config: OK - sources.toml parsed successfully\n✓ sessions: OK - Found sessions: claude_code, codex, cursor\n\nSummary: 6 passed, 1 warning, 0 failed\n\n💡 Run 'cass doctor --fix' to automatically repair detected issues\n```\n\n**Diagnostic Flags**:\n| Flag | Available On | Effect |\n|------|--------------|--------|\n| `--explain` | search | Show query parsing and strategy |\n| `--dry-run` | search | Validate without executing |\n| `--verbose` | most commands | Extra detail in output |\n| `--trace-file` | all | Append execution trace to file |\n\n### Model Management\n\nCommands for managing the semantic search ML model:\n\n```bash\n# Check current model status (abbreviated schema — real output also\n# includes cache_lifecycle, files[], revision, license, and more):\ncass models status --json\n# → {\n#     \"model_id\": \"all-minilm-l6-v2\",\n#     \"model_dir\": \"~/.local/share/coding-agent-search/models/all-MiniLM-L6-v2\",\n#     \"installed\": false,\n#     \"state\": \"not_acquired\",\n#     \"state_detail\": \"model not acquired (user consent required); missing ...\",\n#     \"next_step\": \"Run `cass models install`, or keep using lexical search.\",\n#     \"lexical_fail_open\": true,\n#     \"revision\": \"c9745ed1...\",\n#     \"license\": \"Apache-2.0\",\n#     \"total_size_bytes\": 90872535,\n#     \"installed_size_bytes\": 0,\n#     \"observed_file_bytes\": 0,\n#     \"policy_source\": \"semantic_policy\"\n#   }\n\n# Install model (downloads ~90MB from Hugging Face on explicit request)\ncass models install\n# → Downloads from Hugging Face, verifies checksum\n\n# Install from local directory (air-gapped environments)\ncass models install --from-file /path/to/model-dir\n\n# Verify model integrity\ncass models verify --json\n# → all_valid bool + per-file SHA-256 checks (see `cass models verify --help`)\n\n# Check for model updates\ncass models check-update --json\n# → { \"update_available\": bool, \"reason\": str,\n#     \"current_revision\": str|null, \"latest_revision\": str }\n```\n\n**Model Files** (stored in `$CASS_DATA_DIR/models/all-MiniLM-L6-v2/`):\n- `model.onnx` - The neural network weights (~90MB)\n- `tokenizer.json` - Vocabulary and tokenization rules\n- `config.json` - Model configuration\n- `special_tokens_map.json` - Special token definitions\n- `tokenizer_config.json` - Tokenizer settings\n\n---\n\n## 🔒 Integrity & Safety\n\n- **Verified Install**: The installer enforces SHA256 checksums.\n\n- **Sandboxed Data**: All indexes/DBs live in standard platform data directories (`~/.local/share/coding-agent-search` on Linux).\n\n- **Read-Only Source**: `cass` *never* modifies your agent log files. It only reads them.\n\n### Atomic File Operations\n\n`cass` uses crash-safe atomic write patterns throughout to prevent data corruption:\n\n**TUI State Persistence** (`tui_state.json`):\n```\n1. Serialize state to JSON\n2. Write to temporary file (tui_state.json.tmp)\n3. Atomic rename: temp → final\n```\nIf a crash occurs during step 2, the original file is untouched. The rename operation (step 3) is atomic on all modern filesystems—it either completes fully or not at all.\n\n**ML Model Installation** (`models/all-MiniLM-L6-v2/`):\n```\n1. Download to temp directory (models/all-MiniLM-L6-v2.tmp/)\n2. Verify all checksums\n3. If existing model present: rename to backup (models/all-MiniLM-L6-v2.bak/)\n4. Atomic rename: temp → final\n5. On success: remove backup\n6. On failure: restore from backup\n```\nThis backup-rename-cleanup pattern ensures that either the old model or new model is always available—never a half-installed state.\n\n**Configuration Files** (`sources.toml`, `watch_state.json`):\nAll configuration writes follow the same temp-file-then-rename pattern, ensuring consistency even during power loss or unexpected termination.\n\n**Why This Matters**:\n- System crashes mid-write won't corrupt your preferences\n- Network interruptions during model download won't leave broken installations\n- Concurrent processes won't see partially-written files\n\n\n\n## 📦 Installer Strategy\n\nThe project ships with a robust installer (`install.sh` / `install.ps1`) designed for CI/CD and local use:\n\n- **Checksum Verification**: Validates artifacts against a `.sha256` file or explicit `--checksum` flag.\n\n- **Rustup Bootstrap**: Automatically installs the nightly toolchain if missing.\n\n- **Easy Mode**: `--easy-mode` automates installation to `~/.local/bin` without prompts.\n\n- **Platform Agnostic**: Detects OS/Arch (Linux/macOS/Windows, x86_64/arm64) and fetches the correct binary.\n\n\n\n## 🔄 Automatic Update Checking\n\n`cass` includes a built-in update checker that notifies you when new versions are available, without interrupting your workflow.\n\n### How It Works\n\n1. **Background Check**: On TUI startup, a background thread queries GitHub releases\n2. **Rate Limiting**: Checks run at most once per hour to avoid API rate limits\n3. **Non-Blocking**: Update checks never slow down TUI startup or search operations\n4. **Offline-Safe**: Failed network requests are silently ignored\n\n### Update Notifications\n\nWhen a new version is available, a notification appears in the TUI with:\n- Current version vs. available version\n- Release highlights (from GitHub release notes)\n- Options: **Update Now** | **Skip This Version** | **Remind Later**\n\n### Self-Update Installation\n\nSelecting \"Update Now\" runs the same verified installer used for initial installation:\n\nmacOS/Linux:\n\n```bash\ncurl -fsSL https://...install.sh | bash -s -- --easy-mode --verify\n```\n\nWindows (PowerShell):\n\n```powershell\nirm https://...install.ps1 | iex\n```\n\nThe update process:\n1. Downloads the new binary with SHA256 verification\n2. Backs up the current binary\n3. Replaces with the new version\n4. Prompts to restart `cass`\n\n### Skip Version\n\nIf you're not ready to update, \"Skip This Version\" records the skipped version in persistent state. That specific version won't trigger notifications again, but future versions will.\n\n### Disable Update Checks\n\nFor automated environments or personal preference:\n\n```bash\n# Environment variable\nexport CODING_AGENT_SEARCH_NO_UPDATE_PROMPT=1\n\n# Or for fully headless operation\nexport TUI_HEADLESS=1\n```\n\n### State Persistence\n\nUpdate check state is stored in the data directory:\n- `last_update_check`: Timestamp of last check (for rate limiting)\n- `skipped_version`: Version user chose to skip\n- Both are reset on manual update or by deleting `tui_state.json`\n\n---\n\n## ⚙️ Environment\n\n- **Config**: Loads `.env` via `dotenvy::dotenv().ok()`; configure API/base paths there. Do not overwrite `.env`.\n\n- **Data Location**: Defaults to standard platform data directories (e.g., `~/.local/share/coding-agent-search`). Override with `CASS_DATA_DIR` or `--data-dir`.\n\n- **ChatGPT Support**: The ChatGPT macOS app stores conversations in versioned formats:\n  - **v1** (legacy): Unencrypted JSON in `conversations-{uuid}/` — fully indexed.\n  - **v2/v3**: Encrypted with AES-256-GCM, key stored in macOS Keychain (OpenAI-signed apps only) — detected but skipped.\n\n  Encrypted conversations require keychain access which isn't available to third-party apps. Legacy unencrypted conversations are indexed automatically.\n\n- **Logs**: Written to `cass.log` (daily rotating) in the data directory.\n\n- **Updates**: Interactive TUI checks for GitHub releases on startup. Skip with `CODING_AGENT_SEARCH_NO_UPDATE_PROMPT=1` or `TUI_HEADLESS=1`.\n\n- **Cache tuning**: `CASS_CACHE_SHARD_CAP` (per-shard entries, default 256) and `CASS_CACHE_TOTAL_CAP` (total cached hits across shards, default 2048) control prefix cache size; raise cautiously to avoid memory bloat.\n\n- **Cache debug**: set `CASS_DEBUG_CACHE_METRICS=1` to emit cache hit/miss/shortfall/reload stats via tracing (debug level).\n\n- **Watch testing (dev only)**: `cass index --watch --watch-once path1,path2` triggers a single reindex without filesystem notify (also respects `CASS_TEST_WATCH_PATHS` for backward compatibility); useful for deterministic tests/smoke runs.\n\n### Complete Environment Variable Reference\n\n| Variable | Default | Description |\n|----------|---------|-------------|\n| **Core** | | |\n| `CASS_DATA_DIR` | Platform default | Override data directory |\n| `CASS_DB_PATH` | `$CASS_DATA_DIR/agent_search.db` | Override database path |\n| `CASS_NO_COLOR` | unset | Force monochrome TUI output |\n| `NO_COLOR` | unset | Honored by TUI only when `CASS_RESPECT_NO_COLOR=1` |\n| `CASS_RESPECT_NO_COLOR` | unset | Make TUI inherit global `NO_COLOR` |\n| **Search & Cache** | | |\n| `CASS_CACHE_SHARD_CAP` | 256 | Per-shard LRU cache entries |\n| `CASS_CACHE_TOTAL_CAP` | 2048 | Total cached search hits |\n| `CASS_CACHE_BYTE_CAP` | 10485760 | Cache byte limit (10MB) |\n| `CASS_WARM_DEBOUNCE_MS` | 120 | Warm-up search debounce |\n| `CASS_DEBUG_CACHE_METRICS` | unset | Enable cache hit/miss logging |\n| **Semantic Search** | | |\n| `CASS_SEMANTIC_EMBEDDER` | auto | Force embedder: `hash` or `minilm` |\n| **TUI** | | |\n| `TUI_HEADLESS` | unset | Disable interactive features |\n| `CASS_ALLOW_DUMB_TERM` | unset | Allow TUI startup even when `TERM=dumb` |\n| `CASS_UI_METRICS` | unset | Enable UI interaction tracing |\n| `CASS_DISABLE_ANIMATIONS` | unset | Disable UI animations |\n| `EDITOR` | `$VISUAL` or `vi` | External editor command |\n| `EDITOR_LINE_FLAG` | `+` | Line number flag (e.g., `+42`) |\n| **Updates** | | |\n| `CODING_AGENT_SEARCH_NO_UPDATE_PROMPT` | unset | Disable update notifications |\n| **Connector Overrides** | | |\n| `CASS_AIDER_DATA_ROOT` | `~/.aider.chat.history.md` | Aider history location |\n| `PI_CODING_AGENT_DIR` | `~/.pi/agent/sessions` | Pi-Agent sessions |\n| `CODEX_HOME` | `~/.codex` | Codex data directory |\n| `GEMINI_HOME` | `~/.gemini` | Gemini CLI directory |\n| `OPENCODE_STORAGE_ROOT` | (scans home) | OpenCode storage |\n| `CHATGPT_ENCRYPTION_KEY` | unset | Base64-encoded AES key for ChatGPT v2/v3 |\n\n---\n\n## Sibling Dependency Contract\n\n`cass` pins git revisions in [`Cargo.toml`](Cargo.toml) for `asupersync`, `frankensqlite`/`fsqlite-types`, `franken-agent-detection`, `frankensearch`, `frankentui`, and `toon` (`tru`). The repo also commits local `[patch]` overrides for `frankensqlite`, `franken-agent-detection`, and `frankensearch`; the remaining sibling repos can be switched to `/data/projects/*` checkouts during local development.\n\n| Dependency | Pinned revision |\n|------------|-----------------|\n| `frankensqlite` / `fsqlite-types` | `266dc98f` |\n| `franken-agent-detection` | `029253c` |\n| `asupersync` | `0.3.1` |\n| `frankensearch` | `831b3b13` |\n| `frankentui` | `5f78cfa0` |\n| `toon` (`tru`) | `5669b72a` |\n\n**Build-time validation**\n- `build.rs` validates the active local overrides against the expected package name, package version, patch path, and Cargo feature/default-features contract.\n- If an active sibling checkout has drifted away from the pinned git revision or has a dirty worktree, the build emits a warning instead of silently trusting it.\n- Enable strict enforcement with `cargo check --features strict-path-dep-validation` or `CASS_STRICT_PATH_DEP_VALIDATION=1 cargo check`. Strict mode upgrades drift warnings to hard errors and also validates the optional sibling repos before you switch them to local path overrides.\n\n**Expected interface contract**\n- `frankensqlite` (`fsqlite`): `Connection`, `params!`, and `compat::{ConnectionExt, RowExt}` with `row.get_typed(...)`.\n- `franken-agent-detection`: `AgentDetectOptions` and `detect_installed_agents(...)`.\n- `frankensearch`: `lexical::cass_open_search_reader`, `lexical::ReloadPolicy`, `ModelCategory`, and `ModelTier`.\n- `frankentui`: `ftui::Frame`, `GraphemePool`, `Style`, `ftui-runtime`, `ftui-tty`, and the `ftui-extras` features enabled by cass.\n- `asupersync`: `runtime::RuntimeBuilder` and `http::h1::HttpClient::builder()`.\n- `toon` (`tru`): `toon::encode(...)`.\n\nWhen intentionally updating one of these sibling crates, update the manifest pin, the `build.rs` contract, and the compile-contract test together.\n\n---\n\n## 🩺 Troubleshooting\n\n- **TUI looks monochrome / “1981 mode”**: Check `TERM` and `NO_COLOR`.\n  Full-style launch example:\n  ```bash\n  env -u NO_COLOR TERM=xterm-256color COLORTERM=truecolor cass\n  ```\n  If you intentionally want monochrome, use `CASS_NO_COLOR=1 cass`.\n  If a wrapper keeps forcing `TERM=dumb` and UI still degrades, either fix `TERM` or force raw mode explicitly with `CASS_ALLOW_DUMB_TERM=1 cass`.\n\n- **Checksum mismatch**: Ensure `.sha256` is reachable or pass `--checksum` explicitly. Check proxies/firewalls.\n\n- **Binary not on PATH**: Append `~/.local/bin` (or your `--dest`) to `PATH`; re-open shell.\n\n- **Nightly missing in CI**: Set `RUSTUP_INIT_SKIP=1` if toolchain is preinstalled; otherwise allow installer to run rustup.\n\n- **Watch mode not triggering**: Confirm `watch_state.json` updates and that connector roots are accessible; `notify` relies on OS file events (inotify/FSEvents).\n\n- **Reset TUI state**: Run `cass tui --reset-state` (or press `Ctrl+Shift+Del` in the TUI) to delete `tui_state.json` and restore defaults.\n\n\n\n## 🧪 Developer Workflow\n\nWe target **Rust Nightly** to leverage the latest optimizations.\n\n```bash\n# Format & Lint\ncargo fmt --check\ncargo clippy --all-targets -- -D warnings\n\n# Build & Test\ncargo build --release\ncargo test\n\n# Run End-to-End Tests\ncargo test --test e2e_index_tui\ncargo test --test install_scripts\n```\n\n### Snapshot Baseline Workflow (FrankenTUI)\n\nUse targeted snapshot runs; do not blindly bless everything:\n\n```bash\n# Verify current baselines\ncargo test snapshot_baseline_ -- --nocapture\ncargo test snapshot_search_surface_ -- --nocapture\ncargo test --test ftui_harness_snapshots -- --nocapture\n\n# Regenerate only the suite you intentionally changed\nBLESS=1 cargo test snapshot_baseline_ -- --nocapture\n```\n\nThe full regeneration/review protocol (required reviewer checklist, behavioral guard tests,\nand quality gates) lives in `docs/planning/TESTING.md` under\n`Snapshot Baseline Regeneration & Review (FrankenTUI)`.\n\n### HTML Export E2E Logging\n\nPlaywright E2E runs emit a setup metadata file at `tests/e2e/exports/setup-metadata.json` and\nexport its path as `TEST_EXPORT_SETUP_LOG` in `tests/e2e/.env.test`. On failures, tests attach\nper-test browser logs (console/pageerror/requestfailed). Set `E2E_LOG_ALWAYS=1` to attach logs\nfor every test.\n\n### Release Build Optimizations\n\nThe release profile is aggressively optimized for binary size and performance:\n\n```toml\n[profile.release]\nlto = true              # Link-time optimization across all crates\ncodegen-units = 1       # Single codegen unit for better optimization\nstrip = true            # Remove debug symbols from binary\npanic = \"abort\"         # Smaller panic handling (no unwinding)\nopt-level = \"z\"         # Optimize for size over speed\n```\n\n**Trade-offs**:\n- Build time is significantly longer (~3-5x)\n- Binary size is ~40-50% smaller\n- No stack traces on panic (use debug builds for development)\n\n### CI Pipeline & Artifacts\n\nThe CI pipeline (`.github/workflows/ci.yml`) runs on every PR and push to main:\n\n| Job | Purpose | Artifacts |\n|-----|---------|-----------|\n| `check` | fmt, clippy, tests, benches, UBS scan | None |\n| `e2e` | Integration tests (install, index, filters) | `test-artifacts-e2e` (traces, logs) |\n| `coverage` | Code coverage with llvm-cov | `coverage-report` (lcov.info, summary) |\n\n**Coverage Reports:**\n- `lcov.info` - LCOV format for tools like codecov\n- `coverage-summary.txt` - Human-readable summary\n- Coverage % shown in GitHub Actions step summary\n\n**Test Artifacts:**\n- Trace files from `--trace-file` runs\n- Test run summary logs\n- Retained for 7 days (e2e) / 30 days (coverage)\n\n```bash\n# Generate coverage locally\ncargo install cargo-llvm-cov\ncargo llvm-cov --all-features --workspace --text\n\n# Run specific e2e tests\ncargo test --test e2e_filters -- --test-threads=1\n```\n\n## About Contributions\n\n> *About Contributions:* Please don't take this the wrong way, but I do not accept outside contributions for any of my projects. I simply don't have the mental bandwidth to review anything, and it's my name on the thing, so I'm responsible for any problems it causes; thus, the risk-reward is highly asymmetric from my perspective. I'd also have to worry about other \"stakeholders,\" which seems unwise for tools I mostly make for myself for free. Feel free to submit issues, and even PRs if you want to illustrate a proposed fix, but know I won't merge them directly. Instead, I'll have Claude or Codex review submissions via `gh` and independently decide whether and how to address them. Bug reports in particular are welcome. Sorry if this offends, but I want to avoid wasted time and hurt feelings. I understand this isn't in sync with the prevailing open-source ethos that seeks community contributions, but it's the only way I can move at this velocity and keep my sanity.\n\n---\n"

Aggregates sessions from **11 agents**: Codex, Claude Code, Gemini CLI, Cline, OpenCode, Amp, Cursor, ChatGPT, Aider, Pi-Agent, and Factory (Droid).\n\n## CRITICAL: Robot Mode Required for AI Agents\n\n**NEVER run bare `cass`** - it launches an interactive TUI that blocks your session!\n\n```bash\n# WRONG - blocks terminal\ncass\n\n# CORRECT - JSON output for agents\ncass search \"query\" --robot\ncass search \"query\" --json  # alias\n```\n\n**Always use `--robot` or `--json` flags for machine-readable output.**\n\n---\n\n## Quick Reference for AI Agents\n\n### Pre-Flight Check\n\n```bash\n# Health check (exit 0=healthy, 1=unhealthy, <50ms)\ncass health\n\n# If unhealthy, rebuild index\ncass index --full\n```\n\n### Essential Commands\n\n```bash\n# Find the current session for this workspace\ncass sessions --current --json\n\n# List recent sessions for a specific project\ncass sessions --workspace \"$(pwd)\" --json --limit 5\n\n# Common agent flow: find current session, then export it\ncass export-html \"$(cass sessions --current --json | jq -r '.sessions[0].path')\" --json\n\n# Search with JSON output\ncass search \"authentication error\" --robot --limit 5\n\n# Search with metadata (elapsed_ms, cache stats, freshness)\ncass search \"error\" --robot --robot-meta\n\n# Minimal payload (path, line, agent only)\ncass search \"bug\" --robot --fields minimal\n\n# View source at specific line\ncass view /path/to/session.jsonl -n 42 --json\n\n# Expand context around a line\ncass expand /path/to/session.jsonl -n 42 -C 5 --json\n\n# Capabilities discovery\ncass capabilities --json\n\n# Full API schema\ncass introspect --json\n\n# LLM-optimized documentation\ncass robot-docs guide\ncass robot-docs commands\ncass robot-docs schemas\ncass robot-docs examples\ncass robot-docs exit-codes\n```\n\n---\n\n## Why Use CASS\n\n### Cross-Agent Knowledge Transfer\n\nYour coding agents create scattered knowledge:\n- Claude Code sessions in `~/.claude/projects`\n- Codex sessions in `~/.codex/sessions`\n- Cursor state in SQLite databases\n- Aider history in markdown files\n\nCASS **unifies all of this** into a single searchable index. When you're stuck on a problem, search across ALL your past agent sessions to find relevant solutions.\n\n### Use Cases\n\n```bash\n# \"I solved this before...\"\ncass search \"TypeError: Cannot read property\" --robot --days 30\n\n# Cross-agent learning (what has ANY agent said about X?)\ncass search \"authentication\" --robot --workspace /path/to/project\n\n# Agent-to-agent handoff\ncass search \"database migration\" --robot --fields summary\n\n# Daily review\ncass timeline --today --json\n```\n\n---\n\n## Command Reference\n\n### Indexing\n\n```bash\n# Full rebuild of DB and search index\ncass index --full\n\n# Incremental update (since last scan)\ncass index\n\n# Watch mode: auto-reindex on file changes\ncass index --watch\n\n# Force rebuild even if schema unchanged\ncass index --full --force-rebuild\n\n# Safe retries with idempotency key (24h TTL)\ncass index --full --idempotency-key \"build-$(date +%Y%m%d)\"\n\n# JSON output with stats\ncass index --full --json\n```\n\n### Search\n\n```bash\n# Basic search (JSON output required for agents!)\ncass search \"query\" --robot\n\n# With filters\ncass search \"error\" --robot --agent claude --days 7\ncass search \"bug\" --robot --workspace /path/to/project\ncass search \"panic\" --robot --today\n\n# Time filters\ncass search \"auth\" --robot --since 2024-01-01 --until 2024-01-31\ncass search \"test\" --robot --yesterday\ncass search \"fix\" --robot --week\n\n# Wildcards\ncass search \"auth*\" --robot          #

Discovers SSH hosts from `~/.ssh/config`\n2. Probes each for agent data and cass installation\n3. Optionally installs cass on remotes\n4. Indexes sessions on remotes\n5. Configures `sources.toml`\n6. Syncs data locally\n\n```bash\ncass sources setup --hosts css,csd,yto  # Specific hosts only\ncass sources setup --dry-run             # Preview without changes\ncass sources setup --resume              # Resume interrupted setup\n```\n\n### Manual Setup\n\n```bash\n# Add a remote machine\ncass sources add user@laptop.local --preset macos-defaults\ncass sources add dev@workstation --path ~/.claude/projects --path ~/.codex/sessions\n\n# List sources\ncass sources list --json\n\n# Sync sessions\ncass sources sync\ncass sources sync --source laptop --verbose\n\n# Check connectivity\ncass sources doctor\ncass sources doctor --source laptop --json\n\n# Path mappings (rewrite remote paths to local)\ncass sources mappings list laptop\ncass sources mappings add laptop --from /home/user/projects --to /Users/me/projects\ncass sources mappings test laptop /home/user/projects/myapp/src/main.rs\n\n# Remove source\ncass sources remove laptop --purge -y\n```\n\nConfiguration stored in `~/.config/cass/sources.toml` (Linux) or `~/Library/Application Support/cass/sources.toml` (macOS).\n\n---\n\n## Robot Mode Deep Dive\n\n### Self-Documenting API\n\nCASS teaches agents how to use itself:\n\n```bash\n# Quick capability check\ncass capabilities --json\n# Returns: features, connectors, limits\n\n# Full API schema\ncass introspect --json\n# Returns: all commands, arguments, response shapes\n\n# Topic-based docs (LLM-optimized)\ncass robot-docs commands   # all commands and flags\ncass robot-docs schemas    # response JSON schemas\ncass robot-docs examples   # copy-paste invocations\ncass robot-docs exit-codes # error handling\ncass robot-docs guide      # quick-start walkthrough\ncass robot-docs contracts  # API versioning\ncass robot-docs sources    # remote sources guide\n```\n\n### Forgiving Syntax (Agent-Friendly)\n\nCASS auto-corrects common mistakes:\n\n| What you type | What CASS understands |\n|---------------|----------------------|\n| `cass serach \"error\"` | `cass search \"error\"` (typo corrected) |\n| `cass -robot -limit=5` | `cass --robot --limit=5` (single-dash fixed) |\n| `cass --Robot --LIMIT 5` | `cass --robot --limit 5` (case normalized) |\n| `cass find \"auth\"` | `cass search \"auth\"` (alias resolved) |\n| `cass --limt 5` | `cass --limit 5` (Levenshtein <=2) |\n\n**Command Aliases:**\n- `find`, `query`, `q`, `lookup`, `grep` → `search`\n- `ls`, `list`, `info`, `summary` → `stats`\n- `st`, `state` → `status`\n- `reindex`, `idx`, `rebuild` → `index`\n- `show`, `get`, `read` → `view`\n- `docs`, `help-robot`, `robotdocs` → `robot-docs`\n\n### Output Formats\n\n```bash\n# Pretty-printed JSON (default)\ncass search \"error\" --robot\n\n# Streaming JSONL (header + one hit per line)\ncass search \"error\" --robot-format jsonl\n\n# Compact single-line JSON\ncass search \"error\" --robot-format compact\n\n# With performance metadata\ncass search \"error\" --robot --robot-meta\n```\n\n**Design principle:** stdout = JSON only; diagnostics go to stderr.\n\n### Token Budget Management\n\nLLMs have context limits. Control output size:\n\n| Flag | Effect |\n|------|--------|\n| `--fields minimal` | Only `source_path`, `line_number`, `agent` |\n| `--fields summary` | Adds `title`, `score` |\n| `--fields score,title,snippet` | Custom field selection |\n| `--max-content-length 500` | Truncate long fields (UTF-8 safe) |\n| `--max-tokens 2000` | Soft budget (~4 chars/token) |\n| `--limit 5` | Cap number of results |\n\nTruncated fields include `*_truncated: true` indicator.\n\n---\n\n## Structured Error Handling\n\nErrors are JSON with actionable hints:\n\n```json\n{\n  \"error\": {\n    \"code\": 3,\n    \"kind\": \"index_missing\",\n    \"message\": \"Search index not found\",\n    \"hint\": \"Run 'cass index --full' to build the index\",\n    \"retryable\": false\n  }\n}\n```\n\n### Exit Codes\n\n| Code | Meaning | Action |\n|------|---------|--------|\n| 0 | Success | Parse stdout |\n| 1 | Health check failed | Run `cass index --full` |\n| 2 | Usage error | Fix syntax (hint provided) |\n| 3 | Index/DB missing | Run `cass index --full` |\n| 4 | Network error | Check connectivity |\n| 5 | Data corruption | Run `cass index --full --force-rebuild` |\n| 6 | Incompatible version | Update cass |\n| 7 | Lock/busy | Retry later |\n| 8 | Partial result | Increase `--timeout` |\n| 9 | Unknown error | Check `retryable` flag |\n\n---\n\n## Search Modes\n\nThree search modes, selectable with `--mode` flag:\n\n| Mode | Algorithm | Best For |\n|------|-----------|----------|\n| **lexical** (default) | BM25 full-text | Exact term matching, code searches |\n| **semantic** | Vector similarity | Conceptual queries, \"find similar\" |\n| **hybrid** | Reciprocal Rank Fusion | Balanced precision and recall |\n\n```bash\ncass search \"authentication\" --mode lexical --robot\ncass search \"how to handle user login\" --mode semantic --robot\ncass search \"auth error handling\" --mode hybrid --robot\n```\n\n**Hybrid** combines lexical and semantic using RRF:\n```\nRRF_score = Σ 1 / (60 + rank_i)\n```\n\n---\n\n## Pipeline Mode (Chained Search)\n\nChain searches by piping session paths:\n\n```bash\n# Find sessions mentioning \"auth\", then search within those for \"token\"\ncass search \"authentication\" --robot-format sessions | \\\n  cass search \"refresh token\" --sessions-from -

CM extracts **procedural memory** (rules and playbooks):\n\n```bash\n# 1. CASS indexes raw sessions\ncass index --full\n\n# 2. Search for relevant past experience\ncass search \"authentication timeout\" --robot --limit 10\n\n# 3. CM reflects on sessions to extract rules\ncm reflect\n```\n\n---\n\n## Troubleshooting\n\n| Issue | Solution |\n|-------|----------|\n| \"missing index\" | `cass index --full` |\n| Stale warning | Rerun index or enable watch |\n| Empty results | Check `cass stats --json`, verify connectors detected |\n| JSON parsing errors | Use `--robot-format compact` |\n| Watch not triggering | Check `watch_state.json`, verify file event support |\n| Reset TUI state | `cass tui --reset-state` or `Ctrl+Shift+Del` |\n\n---\n\n## Installation\n\n```bash\n# One-liner install\ncurl -fsSL https://raw.githubusercontent.com/Dicklesworthstone/coding_agent_session_search/main/install.sh \\\n  | bash -s -- --easy-mode --verify\n\n# Windows\nirm https://raw.githubusercontent.com/Dicklesworthstone/coding_agent_session_search/main/install.ps1 | iex\n```\n\n---\n\n## Integration with Flywheel\n\n| Tool | Integration |\n|------|-------------|\n| **CM** | CASS provides episodic memory, CM extracts procedural memory |\n| **NTM** | Robot mode flags for searching past sessions |\n| **Agent Mail** | Search threads across agent history |\n| **BV** | Cross-reference beads with past solutions |\n"

Integration regression benchmarks for cass ingestion/storage paths.\n//!\n//! `SqliteStorage` is now a compatibility alias for `FrankenStorage`, so this\n//! benchmark suite no longer compares rusqlite/legacy SQLite against\n//! frankensqlite.

The intent is to quantify cass application-path overheads honestly. Engine-\n//! level comparison against legacy C SQLite must use a separate harness.\n//!\n//!

Executive Summary\n\nThis document defines explicit coverage targets, phased threshold increases, and justified exclusions for the cass codebase. The goal is to systematically improve test coverage while maintaining development velocity.\n\n---\n\n## 2. Current Baseline\n\n| Metric | Value | Date |\n|--------|-------|------|\n| Line Coverage | 58.33% | 2026-01-27 |\n| Function Coverage | ~55% | 2026-01-27 |\n| Total Tests | ~2,100+ | 2026-01-27 |\n\n### Coverage by Module (Approximate)\n\n| Module | Coverage | Status |\n|--------|----------|--------|\n| connectors/ | 85%+ | Excellent |\n| search/ | 75%+ | Good |\n| storage/ | 70%+ | Good |\n| sources/ | 65%+ | Adequate |\n| ui/ | 60%+ | Adequate |\n| pages/ | 55%+ | Needs Work |\n| indexer/ | 50%+ | Needs Work |\n| lib.rs | <30% | Critical Gap |\n| model/ | <20% | Critical Gap |\n\n---\n\n## 3. Phased Coverage Targets\n\n### Phase 1: Foundation (Current - Q1 2026)\n- **Target**: 60% line coverage (current CI gate)\n- **Focus**: Maintain existing coverage, close critical gaps\n- **Status**: ACHIEVED\n\n### Phase 2: Stability (Q2 2026)\n- **Target**: 70% line coverage\n- **Focus**:\n  - lib.rs unit tests (argument parsing, error types)\n  - model/ serialization tests\n  - encryption.rs expanded tests\n- **Blockers**: None\n\n### Phase 3: Confidence (Q3 2026)\n- **Target**: 80% line coverage\n- **Focus**:\n  - indexer/ comprehensive tests\n  - pages/ export format tests\n  - Error path coverage\n- **Blockers**: Phase 2 completion\n\n### Phase 4: Excellence (Q4 2026)\n- **Target**: 90% line coverage\n- **Focus**:\n  - Edge case completeness\n  - Performance regression tests\n  - Security path hardening\n- **Blockers**: Phase 3 completion\n\n---\n\n## 4. CI Enforcement\n\n### Current Configuration\n```yaml\n# .github/workflows/coverage.yml\nTHRESHOLD=60  # Phase 1 target\n```\n\n### Threshold Schedule\n| Date | Threshold | Notes |\n|------|-----------|-------|\n| 2026-01-27 | 60% | Current |\n| 2026-04-01 | 65% | Mid-Phase 2 |\n| 2026-07-01 | 70% | Phase 2 Complete |\n| 2026-10-01 | 80% | Phase 3 Complete |\n| 2027-01-01 | 85% | Phase 4 Progress |\n| 2027-04-01 | 90% | Phase 4 Complete |\n\n### Enforcement Rules\n1. **PRs**: Must not decrease coverage below threshold\n2. **Main branch**: Coverage report uploaded to Codecov\n3. **Releases**: Must meet current phase target\n\n---\n\n## 5. Justified Exclusions\n\nCertain code paths are intentionally excluded from coverage requirements. These must be documented and reviewed quarterly.\n\n### Permanently Excluded\n\n| Path Pattern | Reason | Review Date |\n|--------------|--------|-------------|\n| `tests/` | Test code itself | N/A |\n| `benches/` | Benchmark code | N/A |\n| `build.rs` | Build script (compile-time only) | N/A |\n| `src/bin/` | Binary entry points (covered by E2E) | 2026-07-01 |\n\n### Temporarily Excluded (To Be Covered)\n\n| Path Pattern | Reason | Target Date |\n|--------------|--------|-------------|\n| `src/pages/wizard.rs` | Complex UI flow, needs E2E | 2026-07-01 |\n| `src/ui/tui.rs:8000+` | TUI rendering (covered by snapshots) | 2026-10-01 |\n| `src/html_export/` | Template rendering (needs fixture tests) | 2026-07-01 |\n\n### Platform-Specific Code\n\n| Path Pattern | Reason |\n|--------------|--------|\n| `#[cfg(target_os = \"macos\")]` | macOS-only (keychain access) |\n| `#[cfg(windows)]` | Windows-specific paths |\n\n---\n\n## 6. Coverage Improvement Workflow\n\n### For Contributors\n\n1. **Before submitting PR**:\n   ```bash\n   # Run coverage locally\n   cargo llvm-cov --lib --ignore-filename-regex \"(tests/|benches/)\"\n   ```\n\n2. **Check coverage delta**:\n   ```bash\n   # Compare with main branch\n   cargo llvm-cov --lib --json > coverage.json\n   jq '.data[0].totals.lines.percent' coverage.json\n   ```\n\n3. **If coverage drops**: Add tests for new code before submitting\n\n### For Maintainers\n\n1. **Quarterly review**: Check exclusion list for stale entries\n2. **Phase transitions**: Update CI threshold on schedule\n3. **Gap reports**: Generate module-level coverage reports monthly\n\n---\n\n## 7. Tools and Commands\n\n### Generate Coverage Report\n```bash\n# Full HTML report\ncargo llvm-cov --lib --html --open \\\n  --ignore-filename-regex \"(tests/|benches/)\"\n\n# JSON summary\ncargo llvm-cov --lib --json \\\n  --ignore-filename-regex \"(tests/|benches/)\" \\\n  --output-path coverage.json\n\n# Codecov format\ncargo llvm-cov --lib --codecov \\\n  --ignore-filename-regex \"(tests/|benches/)\" \\\n  --output-path codecov.json\n```\n\n### Find Uncovered Lines\n```bash\n# Show uncovered regions\ncargo llvm-cov --lib --show-missing-lines \\\n  --ignore-filename-regex \"(tests/|benches/)\"\n\n# Uncovered functions\nscripts/coverage-uncovered.sh\n```\n\n### Per-Module Coverage\n```bash\n# Filter to specific module\ncargo llvm-cov --lib --json | \\\n  jq '.data[0].files[] | select(.filename | contains(\"connectors\"))'\n```\n\n---\n\n## 8. Priority Gaps (from test-coverage-audit.md)\n\n### P0 - Critical (Blocks Releases)\n- [ ] lib.rs unit tests - Argument parsing, error types, command dispatch\n- [ ] model/ unit tests - Core type serialization/conversion\n\n### P1 - High (Next Sprint)\n- [ ] encryption.rs expanded tests - More vectors, error paths\n- [ ] update_check.rs integration tests - Version comparison, network errors\n- [ ] Large archive performance tests - 10K+ conversation benchmarks\n\n### P2 - Medium (Backlog)\n- [ ] Migration rollback tests - Storage schema downgrade paths\n- [ ] TUI interaction coverage - More keyboard/mouse event tests\n- [ ] Error message quality tests - User-facing error strings\n\n### P3 - Low (Nice to Have)\n- [ ] Bookmarks module external tests\n- [ ] Indexer edge case coverage\n- [ ] Export format fidelity tests\n\n---\n\n## 9. Monitoring and Reporting\n\n### Dashboards\n- **Codecov**: https://codecov.io/gh/Dicklesworthstone/coding_agent_session_search\n- **GitHub Actions**: Coverage workflow runs on every PR\n\n### Alerts\n- Coverage drops >2% trigger PR comment\n- Coverage below threshold blocks merge\n\n### Reports\n- Weekly: Coverage trend in team Slack\n- Monthly: Module-level gap report\n- Quarterly: Exclusion list review\n\n---\n\n## 10. FAQ\n\n### Q: Why 90% instead of 100%?\nA: Diminishing returns. The last 10% typically involves:\n- Platform-specific code we can't test in CI\n- Error paths triggered by hardware failures\n- UI rendering code better tested via snapshots\n\n### Q: Can I add code without tests?\nA: Only if:\n1. It's in an excluded category (see Section 5)\n2. You create a follow-up bead to add tests\n3. Total coverage doesn't drop below threshold\n\n### Q: How do I exclude a file from coverage?\nA: Add to the `--ignore-filename-regex` pattern in:\n- `.github/workflows/coverage.yml`\n- This document's exclusion table\n\n### Q: What if CI fails due to coverage?\nA: Either:\n1. Add tests for your new code\n2. If justified, propose an exclusion with rationale\n\n---\n\n## 11.

    "content": "# FrankenTUI UX Architecture\n\nStatus: active\nScope: TUI runtime behavior introduced by the FrankenTUI (ftui) migration\n\nThis document describes the runtime UX architecture that replaced the original ratatui\nrendering layer. It covers the responsive layout system, command palette, inspector\ncockpit, resize coalescer, and style degradation cascade. Future contributors should\nbe able to reason about any UX behavior from this document and the test suites it\nreferences.\n\n---\n\n## Elm Architecture (Model-Update-View)\n\nThe TUI follows the Elm architecture pattern implemented by ftui:\n\n```\nEvent -> CassMsg -> CassApp::update() -> Cmd<CassMsg> -> CassApp::view() -> Frame\n```\n\n`CassApp` (`src/ui/app.rs`) is the single Model. `update()` is a pure state transition\nthat returns `Cmd` values for side effects (async I/O, persistence, subprocess). `view()`\nreads the model and emits rendering instructions. No ad-hoc mutation happens during\nrendering.\n\n**Why this matters**: Any new feature should follow the same cycle. State changes happen\nin `update()`, rendering reads state in `view()`. Side effects are expressed as `Cmd`\nvalues, never as direct calls inside `update()`.\n\n**Key file**: `src/ui/app.rs` (~31k lines)\n**Adapter layer**: `src/ui/ftui_adapter.rs` centralizes high-frequency ftui imports so\ninternal framework changes don't require touching every call site.\n\n---\n\n## Responsive Layout System\n\n### Breakpoints\n\nTerminal width drives a `LayoutBreakpoint` enum with four tiers:\n\n| Breakpoint     | Width (cols) | Behavior |\n|----------------|-------------|----------|\n| `Narrow`       | <80         | Single pane with tab switching; compact density forced |\n| `MediumNarrow` | 80-119      | Dual pane, tight detail column |\n| `Medium`       | 120-159     | Balanced dual pane |\n| `Wide`         | >=160       | Spacious dual pane |\n\nBreakpoints resolve per-frame. Rendering code consults topology contracts instead\nof making ad-hoc width decisions.\n\n### Topology Contracts\n\nEach breakpoint maps to two topology structs:\n\n**SearchTopology**: Controls pane widths, split handle visibility, and dual-pane toggle.\n- Narrow: single pane, no split handle\n- MediumNarrow: 35-col results, 25-col detail, split handle visible\n- Medium: 45/32 split\n- Wide: 50/34 split\n\n**AnalyticsTopology**: Controls tab bar, filter summary, header rows, footer hints.\n- Narrow: no tab bar, no filter summary, zero footer hint slots\n- MediumNarrow: no tab bar, filter summary shown, 2 footer slots (22 chars)\n- Medium/Wide: full tab bar, filter summary, 4 footer slots (52 chars)\n\n**VisibilityPolicy**: Controls optional decorations.\n- Theme name in title bar: hidden on Narrow, shown on MediumNarrow+\n- Saved-view path truncation: 20/40/60/80 chars by tier\n\n### Ultra-Narrow Fallback\n\nTerminals smaller than 30 cols or 6 rows display a \"terminal too small\" message\ninstead of attempting to render a broken layout. This prevents panics and unreadable\ncontent at degenerate sizes.\n\n### Density Modes\n\nThree density modes: Compact, Cozy, Spacious. On terminals <90 cols, the mode\nauto-downgrades to Compact regardless of user preference via `DensityMode::effective()`.\n\n**Key code**: `src/ui/app.rs` lines 908-1231 (topology), lines 1291-1298 (density)\n**Tests**: responsive SIZE_MATRIX suite (16 entries) in `src/ui/app.rs`\n\n---\n\n## Command Palette\n\n### Overview\n\nCtrl+P / Alt+P opens a keyboard-first action dispatch overlay. The palette provides\nfuzzy search over ~28 action variants organized into 7 groups:\n\n| Group      | Actions |\n|------------|---------|\n| Chrome     | Theme toggle, density, help strip, update check |\n| Filter     | Agent, workspace, time-range filters |\n| View       | Saved views, bulk actions, reload |\n| Analytics  | 8 sub-views (Dashboard, Explorer, Heatmap, Breakdowns, Tools, Cost, Plans, Coverage) |\n| Export     | Screenshot formats (HTML, SVG, Text) |\n| Recording  | Macro recording toggle |\n| Sources    | Sources management |\n\n### Match Modes\n\nF9 cycles through match modes: All -> Exact -> Prefix -> WordStart -> Substring -> Fuzzy.\nEach mode trades recall for precision. The default (All) uses Bayesian scoring which adds\n~50us per keystroke but produces better ranking than substring matching.\n\nAlt+B toggles a micro-bench overlay showing queries/second throughput and a latency\nindicator (OK <200us, WARN <1000us, SLOW >=1000us).\n\n### Architecture\n\nThe palette is side-effect free: `PaletteState` produces a `PaletteResult` which the\nparent `update()` dispatches to the appropriate `CassMsg`. This means palette code never\ndirectly mutates application state.\n\n**Key file**: `src/ui/components/palette.rs` (1507 lines, 59 unit tests)\n**Integration tests**: 12 regression tests in `src/ui/app.rs` covering dispatch for all\n28 action variants\n\n---\n\n## Inspector / Explainability Cockpit\n\n### Opening\n\nCtrl+Shift+I opens the inspector overlay with 7 tabs:\nTiming, Layout, HitRegions, Resize, Diff, Budget, Timeline.\n\n### Cockpit Panels\n\nThe cockpit surfaces causal explanations for adaptive runtime decisions through\n4 panel types:\n\n| Panel | What it explains |\n|-------|-----------------|\n| `DiffStrategy` | Full vs partial redraw decisions, dirty-row counts, reason strings |\n| `ResizeRegime` | Steady vs Burst regime classification, BOCPD probability, event history |\n| `BudgetHealth` | Frame budget vs actual time, degradation level, PID controller state |\n| `Timeline` | Chronological feed of decision events with severity markers |\n\n### Data Flow\n\nInspector data comes from ftui's per-tick evidence telemetry. The cockpit does not\nparse logs at render time. Instead, ftui emits typed snapshots (`DiffStrategySnapshot`,\n`ResizeDecisionSnapshot`, `BudgetSnapshot`) which the model stores in ring buffers.\n\n### Cockpit Topology\n\nThe cockpit adapts to terminal size through `LayoutBreakpoint x CockpitMode` topology\ncontracts:\n\n- Narrow overlay: 42x10 max, single-char tab labels (T L H R D B G)\n- Narrow expanded: 42x16 max\n- MediumNarrow: 56x12 overlay / 56x22 expanded, full labels\n- Medium/Wide overlay: 66x16, full labels\n- Medium/Wide expanded: 72x30, up to 18 timeline events\n\nThe cockpit auto-disables when the terminal is smaller than 20x6.\n\n**Key code**: `src/ui/data.rs` lines 370-724 (data contracts), `src/ui/app.rs` lines 1235-1244 (topology)\n**Tests**: cockpit topology tests in `src/ui/app.rs`\n\n---\n\n## Resize Coalescer (BOCPD)\n\nThe TUI uses Bayesian Online Changepoint Detection to classify resize event streams\ninto Steady and Burst regimes. This prevents the \"thundering herd\" problem where\nrapid terminal resizing (e.g., dragging a window edge) triggers dozens of redundant\nrelayouts.\n\n### How It Works\n\n1. Each resize event records its inter-arrival time\n2. BOCPD computes the probability that the resize rate has changed regime\n3. In Burst regime, the coalescer delays relayout until the rate stabilizes\n4. In Steady regime, resizes apply immediately\n\nThe \"responsive\" preset (`BocpdConfig::responsive()`) uses lower thresholds for\nfaster changepoint detection.\n\n### Evidence Capture\n\nThe resize regime and BOCPD probability are surfaced in the inspector's Resize\npanel via `ResizeRegimeContract` fields: regime label, burst probability, recommended\ndelay, event rate, and last action taken (apply/defer/coalesce).\n\n**Key code**: `src/ui/app.rs` lines 1718-1830 (resize handling), `src/ui/data.rs` lines 507-553 (contract)\n\n---\n\n## Style & Degradation System\n\n### Degradation Cascade\n\nSix degradation levels, from full fidelity to frame skipping:\n\n| Level | What renders |\n|-------|-------------|\n| `Full` | All styling, rounded borders, icons, gradients |\n| `SimpleBorders` | Plain box-drawing (no rounded corners) |\n| `NoStyling` | Square borders, no fg/bg colors |\n| `EssentialOnly` | No borders, no icons, minimal content |\n| `Skeleton` | Bare structure only |\n| `SkipFrame` | Skip rendering entirely |\n\nDegradation is driven by ftui's frame budget PID controller. When frame times exceed\nthe budget, the degradation level increases. When headroom returns, it decreases.\n\n### DecorativePolicy\n\nThe function `DecorativePolicy::resolve()` maps\n(StyleOptions, DegradationLevel, LayoutBreakpoint, fancy_borders) to a concrete\nrendering policy with fields: `border_tier`, `show_icons`, `use_styling`,\n`use_gradients`, `render_content`. Rendering code checks this policy instead of\nmaking independent decisions about what to draw.\n\n### Color Profile Detection\n\nPrecedence rules for color profile selection:\n\n1. `CASS_NO_COLOR=1` -> Mono profile, no_color mode\n2. `CASS_RESPECT_NO_COLOR=1` + `NO_COLOR` set -> Mono profile\n3. `CASS_COLOR_PROFILE=<value>` -> use explicit value (mono/ansi16/ansi256/truecolor)\n4. Otherwise -> detect from terminal capabilities (COLORTERM, TERM env vars)\n\n### Semantic Tokens\n\nWidgets reference semantic token names (e.g., `STYLE_STATUS_SUCCESS`, `STYLE_ROLE_USER`)\nrather than raw colors. Theme preset changes and degradation level changes propagate\nautomatically through all widgets without per-widget updates.\n\n19 named color slots: primary, secondary, accent, bg, surface, overlay, text,\ntext_muted, text_subtle, success, warning, error, info, border, border_focused,\nselection, scrollbar.\n\n### Theme Customization\n\nCtrl+Shift+T opens the interactive theme editor with hex input, preset cycling\n(Dark, Light, HighContrast, Catppuccin, Dracula, Nord), WCAG contrast warnings,\nand export to `~/.config/cass/theme.toml`.\n\n**Key file**: `src/ui/style_system.rs` (4914 lines)\n**Key file**: `docs/tui_style_spec.md` (full color/spacing/motion spec)\n**Tests**: degradation transition monotonicity tests, capability matrix tests\n\n---\n\n## Modal Priority Stack\n\nModal interceptors form a priority stack:\n\n```\ntheme editor > inspector > palette > normal key handling\n```\n\nWhen a modal is open, it captures all input except its own dismiss keybinding.\nNew modals should insert at the appropriate priority level and follow the same\ncapture/dismiss pattern.\n\n---\n\n## Accessibility\n\n- `CASS_A11Y=1` enables accessible mode: text role markers, bold/underline accents,\n  icon suppression\n- `CASS_NO_ICONS=1` disables Unicode icons\n- `CASS_NO_GRADIENT=1` disables gradient effects\n- NO_COLOR standard is respected (with configurable override via CASS_RESPECT_NO_COLOR)\n- Minimum contrast ratio target: 4.5:1 for all text\n- 8-color terminal fallback: high-contrast flat palette, no gradients, no alpha\n\n**Full spec**: `docs/ACCESSIBILITY.md`\n\n---\n\n## Test Coverage Pointers\n\n| Area | Location | Count |\n|------|----------|-------|\n| Palette lifecycle + dispatch | `src/ui/app.rs`, `src/ui/components/palette.rs` | ~71 tests |\n| Responsive layout (SIZE_MATRIX) | `src/ui/app.rs` | 16 entries |\n| Degradation cascades | `src/ui/style_system.rs` | monotonicity + capability tests |\n| Inspector cockpit | `src/ui/app.rs`, `src/ui/data.rs` | topology + contract tests |\n| Cross-workstream integration | `tests/cross_workstream_integration.rs` | 74 tests |\n| Visual parity | `docs/ftui_visual_parity_rubric.md` | scoring rubric |\n\n---\n\n## Design Decision Log\n\n### Why Elm Architecture?\n\nSeparating state transitions (update) from rendering (view) eliminates an entire class\nof bugs where rendering code mutates state mid-frame. It also makes the TUI testable:\nunit tests can call `update()` with a message and assert on the resulting state without\nneeding a terminal.\n\n### Why Breakpoint Contracts Instead of Ad-Hoc Width Checks?\n\nEarly versions used scattered `if width > N` checks. These were hard to maintain and\nproduced inconsistent behavior. Topology contracts centralize layout decisions: change\nthe contract once and all rendering code follows.\n\n### Why BOCPD for Resize?\n\nSimple debounce (fixed delay) either introduces visible latency on single resizes or\nfails to coalesce rapid resize bursts. BOCPD adapts: it detects the statistical\nboundary where resize rate changes, applying resizes immediately in steady state\nand coalescing during bursts.\n\n### Why Semantic Tokens Instead of Direct Colors?\n\nDirect color references create tight coupling between theme presets and widget code.\nSemantic tokens provide an indirection layer: themes define token values, widgets\nreference tokens, and the degradation system can override token resolution without\ntouching widget code.\n"

Installs rustup nightly via rustup-init.exe if needed. PATH guidance.\n\n## Open items\n- Minisign integration (fail-closed when pubkey provided).\n- Windows rustup install may require x86 vs x64 detection; prefer native rustup-init.exe.\n- Watch-mode e2e quickstart optional.\n"

Anyone with the recovery secret can decrypt the archive.\n\n### QR Code Generation\n\nRecovery secrets can be displayed as QR codes for offline backup:\n\n```bash\ncass pages key show-recovery --archive ./archive --qr\n```\n\nThe QR code contains the base64url-encoded secret and can be scanned to restore access.\n\n### Using a Recovery Key\n\nTo unlock an archive with a recovery key:\n\n```bash\n# Interactive\ncass pages decrypt ./archive\n\n# Programmatic (stdin)\necho \"base64url-secret-here\" | cass pages decrypt ./archive --recovery-stdin\n```\n\n---\n\n## Multi-Key-Slot Operations\n\n### Listing Key Slots\n\n```bash\ncass pages key list --archive ./archive\n```\n\nOutput:\n```\nKey Slots:\n  Slot 0: password (Argon2id)\n  Slot 1: recovery (HKDF-SHA256)\n\nActive slots: 2\n```\n\n### Adding a Password Slot\n\nAdd an additional password to an existing archive:\n\n```bash\ncass pages key add-password --archive ./archive\n```\n\nYou'll be prompted for:\n1. Current password (to authenticate)\n2. New password (to add)\n\n### Adding a Recovery Slot\n\nAdd a recovery key to an existing archive:\n\n```bash\ncass pages key add-recovery --archive ./archive\n```\n\n**Save the displayed recovery secret immediately.**\n\n### Revoking a Key Slot\n\nRemove a key slot:\n\n```bash\ncass pages key revoke --archive ./archive --slot 1\n```\n\n**Constraints:**\n- Cannot revoke the last remaining slot\n- Cannot revoke the slot you're authenticating with\n- Revoked slot IDs are never reused\n\n### Key Rotation\n\nFull key rotation regenerates the DEK and re-encrypts all data:\n\n```bash\ncass pages key rotate --archive ./archive\n```\n\nOptions:\n- `--keep-recovery`: Generate new recovery key after rotation\n- Default: Creates single password slot\n\n**When to rotate:**\n- Suspected key compromise\n- Personnel changes\n- Regular security hygiene\n\n---\n\n## Disaster Recovery\n\n### Scenario: Forgotten Password\n\nIf you have a recovery key:\n\n```bash\ncass pages decrypt ./archive --recovery\n# Enter recovery secret when prompted\n```\n\nThen add a new password:\n\n```bash\ncass pages key add-password --archive ./archive\n```\n\n### Scenario: Corrupted config.json\n\nSymptoms:\n- \"Failed to parse config\" errors\n- \"Invalid JSON\" errors\n\nRecovery steps:\n\n1. **Check for backup:** Look for `config.json.bak` or version control\n2. **Restore from backup:** Copy backup over corrupted file\n3. **If no backup:** Archive is likely unrecoverable without config.json\n\nPrevention: Always keep backups of encrypted archives.\n\n### Scenario: Corrupted Payload Chunks\n\nSymptoms:\n- \"Authentication failed\" during decryption\n- \"Invalid chunk\" errors\n\nVerification:\n\n```bash\ncass pages verify --archive ./archive\n```\n\nIf specific chunks are corrupted:\n- Restore from backup\n- If backup unavailable, data in corrupted chunks is lost\n\n### Scenario: Missing Files\n\nUse integrity verification:\n\n```bash\ncass pages verify --archive ./archive --check-integrity\n```\n\nThis validates:\n- All files listed in config.json exist\n- SHA-256 hashes match integrity.json (if present)\n\n---\n\n## Best Practices\n\n### Backup Strategy\n\n1. **Store recovery key offline:** Print QR code, store in safe\n2. **Backup entire archive:** Include config.json and all payload chunks\n3. **Test recovery regularly:** Verify you can decrypt with recovery key\n4. **Geographic distribution:** Store backups in multiple locations\n\n### Key Management\n\n1. **Use strong passwords:** Minimum 12 characters, mixed case/numbers/symbols\n2. **Limit key slots:** Only create slots you need\n3. **Revoke unused slots:** Remove access when no longer needed\n4. **Rotate after incidents:** Change keys if compromise suspected\n\n### Verification Checklist\n\nBefore relying on an archive:\n\n- [ ] Password unlocks archive\n- [ ] Recovery key unlocks archive\n- [ ] `cass pages verify` passes\n- [ ] Backup copy exists and is verified\n- [ ] Recovery secret stored securely offline\n\n---\n\n## Troubleshooting\n\n### Error: \"Invalid password or no matching key slot\"\n\n**Causes:**\n- Typo in password\n- Wrong password\n- Password slot was revoked\n\n**Solutions:**\n- Try recovery key\n- Check for password manager entry\n- Verify slot exists with `key list`\n\n### Error: \"Cannot revoke the last remaining key slot\"\n\n**Cause:** Attempting to revoke the only active slot\n\n**Solution:** Add another slot first, then revoke\n\n### Error: \"Cannot revoke slot used for authentication\"\n\n**Cause:** Trying to revoke the slot you authenticated with\n\n**Solution:** Use a different password/recovery to authenticate\n\n### Error: \"Key unwrapping failed\"\n\n**Causes:**\n- Corrupted wrapped_dek\n- Wrong password/recovery key\n- Modified config.json\n\n**Solutions:**\n- Try different credentials\n- Restore config.json from backup\n- Use recovery key if available\n\n### Error: \"Chunk authentication failed\"\n\n**Cause:** Payload chunk was modified or corrupted\n\n**Solutions:**\n- Restore chunk from backup\n- If backup unavailable, that chunk's data is lost\n\n### Error: \"Missing chunk file\"\n\n**Cause:** Payload file was deleted or not copied\n\n**Solution:** Restore from backup\n\n---\n\n## Security Considerations\n\n### What Recovery Keys Provide\n\nRecovery keys provide full access to archive contents, equivalent to the primary password. They are designed for:\n\n- Emergency access when password is forgotten\n- Backup administrators\n- Estate planning\n\n### What Recovery Keys Don't Protect Against\n\n- Compromised recovery key\n- Corrupted payload data\n- Deleted archive files\n\n### Secure Storage\n\nStore recovery keys:\n- Printed and sealed in safe deposit box\n- Hardware security module (HSM)\n- Password manager with separate master password\n- Split across multiple locations (Shamir's Secret Sharing)\n\n**Never store:**\n- In plaintext files\n- In email\n- In cloud storage without additional encryption\n- On the same device as the archive\n"

Lexical is required; semantic refinement joins when ready.\n- Paginate: use `_meta.next_cursor` → `cass search \"query\" --robot --cursor <value>`\n- Budget tokens: `--max-tokens 200 --robot-meta`\n- Minimal fields: `--fields minimal` (path,line,agent)\n- Freshness and fallback hints: `--robot-meta` (adds search mode, semantic refinement, lexical fallback reason, index freshness, and warnings)\n- View source: `cass view <path> -n <line> --json`\n- Health: `cass health --json` or `cass state --json`\n\n## Core commands for agents\n| Need | Command |\n| --- | --- |\n| Search with JSON | `cass search \"panic\" --robot` |\n| Search today | `cass search \"auth\" --robot --today` |\n| Wildcards | `cass search \"http*\" --robot` |\n| Aggregations | `cass search \"error\" --robot --aggregate agent,workspace` |\n| Pagination | pass `_meta.next_cursor` back via `--cursor` |\n| Limit output fields | `--fields minimal` or comma list (`source_path,line_number,agent,title`) |\n| Truncate content | `--max-content-length 400` or budgeted `--max-tokens 200` |\n| Metadata | `--robot-meta` (elapsed_ms, cache stats, index freshness, cursor, warnings) |\n| Health snapshot | `cass state --json` (alias `status`) |\n| Capabilities | `cass capabilities --json` |\n| Introspection | `cass introspect --json` (schemas for responses) |\n\n## Search asset contract\n- SQLite is the source of truth for indexed conversations and messages.\n- Lexical search is the required fast path. If the lexical derivative is missing, stale, schema-drifted, or corrupt, cass reports that state and should rebuild it from SQLite instead of requiring routine manual repair.\n- Hybrid is the default search intent. With `--robot-meta`, `_meta.requested_search_mode`, `_meta.search_mode`, `_meta.semantic_refinement`, `_meta.fallback_tier`, and `_meta.fallback_reason` tell agents what actually happened.\n- Semantic search is opportunistic enrichment. Lexical-only behavior is expected during first indexing, semantic backfill, disabled semantic policy, or missing local model/vector assets.\n- Treat `recommended_action` from health/status as authoritative. Do not run repair commands by habit when cass is already rebuilding or when lexical fallback is an expected state.\n\n## Response shapes (robot)\n- Search:\n  - top-level: `query, limit, offset, count, total_matches, hits, cursor, hits_clamped, request_id`\n  - `_meta` (with `--robot-meta`): `elapsed_ms, search_mode, requested_search_mode, mode_defaulted, semantic_refinement, fallback_tier, fallback_reason, wildcard_fallback, cache_stats{hits,misses,shortfall}, tokens_estimated, max_tokens, next_cursor, hits_clamped, state{index, database}, index_freshness`\n  - `_warning` present when index is stale (age/pending sessions)\n  - `aggregations` present when `--aggregate` is used\n- State/Status: `status, healthy, initialized, recommended_action, index{exists,fresh,last_indexed_at,age_seconds,stale}, database{exists,conversations,messages,path}, pending{sessions,watch_active}, rebuild{active,...}, semantic{status,availability,can_search,fallback_mode,hint}, _meta{timestamp,data_dir,db_path}`\n- Capabilities: `crate_version, api_version, contract_version, documentation_url, features[], connectors[], limits{max_limit,max_content_length,max_fields,max_agg_buckets}`\n\n## Flags worth knowing\n- `--fields minimal|summary|<list>`: reduce payload size\n- `--max-content-length N` / `--max-tokens N`: truncate per-field / by budget\n- `--robot-format json|jsonl|compact`: choose encoding\n- `--request-id ID`: echoed in results/meta; good for correlation\n- Time filters: `--today --yesterday --week --days N --since DATE --until DATE`\n- Aggregations: `--aggregate agent,workspace,date,match_type`\n- Output display (humans): `--display table|lines|markdown`\n- Progress: `--progress bars|plain|none|auto`; Color: `--color auto|always|never`\n\n## Best practices for agents\n- Always pass `--robot`/`--json` and `--robot-meta` when you care about freshness or pagination.\n- Use `--fields minimal` during wide scans; fetch details with `cass view` if needed.\n- Respect `_warning`, `index_freshness.stale`, and health/status `recommended_action`; run `cass index --full` for first setup or explicit recommended refresh, not as a blind repair loop.\n- Treat lexical fallback in default hybrid search as expected when semantic assets are not ready. Escalate only when lexical itself is unavailable after the recommended rebuild path.\n- Store `_meta.next_cursor` for long result sets; avoid re-running the base query.\n- Include `--request-id` to correlate retries and logs.\n- Clamp limits to published caps (see `cass capabilities --json`).\n- Prefer `--max-tokens` to keep outputs small in LLM loops.\n\n## TUI drill-in contract (operator reference)\n- `Enter` with a selected hit opens the contextual detail modal on the Messages tab.\n- `Enter` with no selected hit follows query-submit behavior (safe no-op when query is empty).\n- In detail modal: `/` opens find, `n`/`N` navigate matches, `Esc` exits find before closing the modal.\n- Use `F8` to open the selected hit in `$EDITOR` when you need raw file navigation.\n\n## Integration snippets\n\n### Python\n```python\nimport json, subprocess\n\ncmd = [\"cass\", \"search\", \"error\", \"--robot\", \"--robot-meta\", \"--max-tokens\", \"200\"]\nout = subprocess.check_output(cmd, text=True)\ndata = json.loads(out)\nprint(data[\"_meta\"][\"elapsed_ms\"], \"ms\", \"hits:\", len(data[\"hits\"]))\n```\n\n### Node.js\n```js\nimport { execFileSync } from \"node:child_process\";\n\nconst out = execFileSync(\"cass\", [\"search\", \"timeout\", \"--robot\", \"--fields\", \"minimal\"], { encoding: \"utf8\" });\nconst result = JSON.parse(out);\nconsole.log(result.hits.map(h => `${h.source_path}:${h.line_number || 0}`).join(\"\\n\"));\n```\n\n### Bash\n```bash\ncass search \"panic\" --robot --fields minimal --robot-meta \\\n  | jq -r '.hits[] | \"\\(.source_path):\\(.line_number // 0) \\(.title // \"\")\"'\n```\n\n## Troubleshooting\n- “not initialized” → run `cass index --full` once\n- Stale warning → read `recommended_action`; wait if rebuild is active, otherwise refresh with `cass index`\n- Hybrid returned lexical → check `_meta.fallback_reason`; this is normal when semantic assets are unavailable or backfilling\n- Empty results but expected matches → try `--aggregate agent,workspace` to confirm ingest; check `watch_state.json` pending\n- JSON parsing errors → use `--robot-format compact` to avoid pretty whitespace issues\n\n## Change log (robot-facing)\n- 2026-04-22: Documented hybrid-default search, lexical self-heal expectations, semantic fail-open metadata, and health/status readiness contract.\n- 0.1.30: `_meta.index_freshness` + `_warning` in search robot output; capabilities limits enforced; cursor/request-id exposed.\n\n---\nFor deeper schemas: `cass introspect --json` and `cass capabilities --json`.\n"

    "content": "# CASS Security Audit Report\n\n## Executive Summary\n\n**Project**: cass (Coding Agent Session Search)\n**Version**: 0.1.55\n**Audit Date**: 2026-01-12\n**Audit Scope**: Encrypted Pages Export Feature\n\n### Overall Assessment\n\nThe cryptographic implementation demonstrates strong security architecture with enterprise-grade envelope encryption. The design follows industry best practices with multi-slot key wrapping (LUKS-like), Argon2id for password-based key derivation, and AES-256-GCM for authenticated encryption.\n\n**One high-severity issue was identified** in the nonce derivation logic that should be addressed.\n\n---\n\n## Summary Statistics\n\n| Category | Count |\n|----------|-------|\n| **Total Items Reviewed** | 56 |\n| **Passed** | 44 |\n| **Critical Findings** | 0 |\n| **High Findings** | 1 |\n| **Medium Findings** | 2 |\n| **Low Findings** | 2 |\n| **Advisory** | 1 |\n| **Pending Documentation** | 5 |\n| **N/A** | 4 |\n\n---\n\n## Findings\n\n### HIGH-001: XOR-Based Chunk Nonce Derivation\n\n**Severity**: HIGH\n**Status**: FIXED (2026-01-12)\n**Location**: `src/pages/encrypt.rs:536-544`\n\n**Description**:\nThe chunk nonce derivation uses XOR to combine a base nonce with the chunk index:\n\n```rust\nfn derive_chunk_nonce(base_nonce: &[u8; 12], chunk_index: u32) -> [u8; 12] {\n    let mut nonce = *base_nonce;\n    let idx_bytes = chunk_index.to_be_bytes();\n    for i in 0..4 {\n        nonce[8 + i] ^= idx_bytes[i];\n    }\n    nonce\n}\n```\n\n**Risk**:\nXOR-based nonce derivation is not the recommended approach for counter-mode nonces. While the random base nonce provides uniqueness across exports, the XOR operation could theoretically create collisions in edge cases. NIST SP 800-38D recommends either:\n1. Random nonces (with proper collision resistance)\n2. Deterministic counter nonces (with proper incrementing)\n\n**Impact**:\nWith the current 32-bit chunk counter limit (~4 billion chunks) and random 12-byte base nonce, the practical collision risk is minimal. However, this deviates from best practices.\n\n**Recommended Remediation**:\nReplace XOR with direct byte assignment or proper counter increment:\n\n```rust\nfn derive_chunk_nonce(base_nonce: &[u8; 12], chunk_index: u32) -> [u8; 12] {\n    let mut nonce = *base_nonce;\n    // Direct assignment of counter bytes (safer pattern)\n    nonce[8..12].copy_from_slice(&chunk_index.to_be_bytes());\n    nonce\n}\n```\n\n**Note**: The JavaScript implementation in `crypto_worker.js:328-342` must be updated in tandem.\n\n---\n\n### MEDIUM-001: Base64 Encoding Using Deprecated APIs\n\n**Severity**: MEDIUM\n**Status**: OPEN\n**Location**: `src/pages_assets/crypto_worker.js:543-561`\n\n**Description**:\nThe JavaScript implementation uses `atob()` and `btoa()` for base64 encoding, which are deprecated and have known issues with binary data and non-ASCII characters.\n\n**Risk**:\nWhile functional for the current use case (pure binary data), these APIs may cause issues with certain byte sequences and are not recommended for new code.\n\n**Recommended Remediation**:\nConsider using modern alternatives or the existing implementations are acceptable for binary-safe base64 (which is the current use case).\n\n---\n\n### MEDIUM-002: Optional LocalStorage DEK Persistence\n\n**Severity**: MEDIUM\n**Status**: ADVISORY\n**Location**: `src/pages_assets/session.js:88-95`\n\n**Description**:\nUsers can optionally store encrypted DEK in localStorage for session persistence. While the DEK is encrypted with a session key, localStorage persists indefinitely.\n\n**Risk**:\nAn attacker with browser access could potentially recover the encrypted DEK blob. The session key provides protection, but this extends the attack surface.\n\n**Recommended Remediation**:\n- Document the risk clearly to users\n- Consider enforcing memory-only storage for highest security\n- Current implementation is acceptable as it's opt-in\n\n---\n\n### LOW-001: Session Key Without Domain Separation\n\n**Severity**: LOW\n**Status**: OPEN\n**Location**: `src/pages_assets/session.js:295`\n\n**Description**:\nSession key generation uses only random bytes without domain separation:\n\n```javascript\ngenerateSessionKey() {\n    return crypto.getRandomValues(new Uint8Array(32));\n}\n```\n\n**Risk**:\nMinimal. The random 32 bytes provide sufficient entropy. Domain separation would add defense-in-depth.\n\n**Suggested Enhancement**:\nConsider deriving session key with HKDF including page origin as context.\n\n---\n\n### LOW-002: Worker Library Loading Without SRI\n\n**Severity**: LOW\n**Status**: ADVISORY\n**Location**: `src/pages_assets/crypto_worker.js:512-534`\n\n**Description**:\nWeb Worker loads libraries via `importScripts()` without integrity verification.\n\n**Risk**:\nRelies on CSP and same-origin policy. Since all assets are bundled with the export, this is acceptable for the current deployment model.\n\n**Recommended Remediation**:\nNo action required for static bundle deployment.\n\n---\n\n## Strengths Identified\n\n### Cryptographic Architecture\n- **Envelope Encryption**: Proper DEK/KEK separation\n- **Multi-Slot Key Wrapping**: LUKS-inspired design allows multiple unlock methods\n- **Argon2id**: Strong password-based KDF with appropriate parameters (64MB, t=3, p=4)\n- **AES-256-GCM**: Industry-standard AEAD with proper key sizes\n\n### Key Management\n- **Unique Salts**: Each key slot uses unique random salt\n- **AAD Usage**: Chunk and slot operations include authenticated additional data\n- **Zeroization**: Keys are zeroed on drop (`ZeroizeOnDrop` trait)\n\n### JavaScript Implementation\n- **Web Worker Isolation**: Crypto operations isolated in worker thread\n- **HKDF Interoperability**: Rust and JS implementations match\n- **Session Management**: Proper timeout and cleanup\n\n### Web Security\n- **CSP**: Restrictive Content Security Policy\n- **COOP/COEP**: Cross-origin isolation enabled\n- **TOFU Fingerprinting**: Detects archive tampering\n\n---\n\n## Compliance Summary\n\n| Standard | Status | Notes |\n|----------|--------|-------|\n| NIST SP 800-38D (AES-GCM) | PARTIAL | Nonce derivation needs review |\n| RFC 9106 (Argon2) | COMPLIANT | Parameters meet recommendations |\n| RFC 5869 (HKDF) | COMPLIANT | Proper usage with info string |\n| OWASP Crypto Guidelines | COMPLIANT | Zeroization, AAD usage |\n\n---\n\n## Recommendations\n\n### Priority 1 (Should Address)\n1. **Fix chunk nonce derivation** - Replace XOR with direct counter bytes\n\n### Priority 2 (Consider Addressing)\n2. **Add threat model documentation**\n3. **Add key rotation procedures documentation**\n4. **Add incident response documentation**\n\n### Priority 3 (Optional Enhancements)\n5. Consider domain separation for session keys\n6. Document localStorage risks more prominently\n\n---\n\n## Conclusion\n\nThe cass encrypted export feature demonstrates a well-engineered cryptographic system. The envelope encryption architecture with multiple key slots is sophisticated and follows established patterns (LUKS). All core cryptographic primitives (AES-256-GCM, Argon2id, HKDF-SHA256) are correctly configured.\n\nThe single high-severity finding (XOR-based nonce derivation) should be addressed, though the practical risk is low given the random base nonce and expected usage patterns. All other findings are advisory or low severity.\n\n**Overall Security Rating**: **GOOD** with minor improvements recommended.\n\n---\n\n## Audit Artifacts\n\n- `docs/SECURITY_AUDIT_CHECKLIST.md` - Full item-by-item checklist\n- `docs/SECURITY_AUDIT_REPORT.md` - This report\n\n## Reviewer\n\n- **Auditor**: Claude Code (AI-Assisted Review)\n- **Date**: 2026-01-12\n"

    "content": "# ftui/ftui-extras Feature Audit for cass\n\nBead: `coding_agent_session_search-3nwtd.2.1`  \nDate: 2026-02-13  \nOwner: `GreenMountain`\n\n## Scope and method\n\nThis audit compares:\n\n1. What is available in pinned FrankenTUI (`ftui` + `ftui-extras`) at commit `f0ad8a6d9b016ce6a000dc5e1461e1411aee1441`.\n2. What cass currently uses in `src/ui/*` and related UI paths.\n3. Which high-value capabilities are currently unused.\n\nPrimary evidence:\n\n- `Cargo.toml` and `Cargo.lock` (pinned rev + enabled features)\n- `crates/ftui-extras/src/*` and `crates/ftui-widgets/src/lib.rs` in the pinned checkout\n- cass usage scans in `src/ui/app.rs`, `src/ui/analytics_charts.rs`, `src/ui/style_system.rs`\n\n## Version and enabled features\n\nFrom `Cargo.toml`, cass enables `ftui-extras` features:\n\n- `markdown`, `syntax`, `charts`, `canvas`, `theme`, `clipboard`, `clipboard-fallback`, `export`, `visual-fx`, `forms`, `validation`, `help`\n\nPinned to:\n\n- `ftui` `0.1.1` at `f0ad8a6d9b016ce6a000dc5e1461e1411aee1441`\n- `ftui-extras` `0.1.1` at same rev\n\n## Capability inventory vs current usage\n\n### ftui-extras feature modules\n\n| Feature | Key public capabilities | cass usage now | Evidence |\n|---|---|---|---|\n| `charts` | `Sparkline`, `BarChart`, `LineChart`, `heatmap_gradient` | Used heavily in analytics | `src/ui/analytics_charts.rs:17`, `src/ui/analytics_charts.rs:19` |\n| `canvas` | `Painter` + `CanvasRef`, modes (`Braille`, `Block`, `HalfBlock`), primitives (`point`, `line`, `rect`, `rect_filled`, `polygon_filled`, `circle`) | Used narrowly for heatmap raster fill | `src/ui/analytics_charts.rs:16`, `src/ui/analytics_charts.rs:1069` |\n| `markdown` | `MarkdownRenderer`, `MarkdownTheme`, markdown detection helpers | Used in detail modal rendering | `src/ui/app.rs:141`, `src/ui/style_system.rs:25` |\n| `clipboard` | `Clipboard::auto`, selections/backends | Used for copy actions | `src/ui/app.rs:15560` |\n| `export` | `HtmlExporter`, `SvgExporter`, `TextExporter` | Used for screenshot export path | `src/ui/app.rs:14565` |\n| `visual-fx` | `FxQuality`, `Backdrop`, `Scrim`, `FxLayer`, `StackedFx`, effects (`MetaballsFx`, `PlasmaFx`), canvas adapters | Not used | no `ftui_extras::visual_fx` usage in `src/` |\n| `forms` | `Form`, `FormField`, `FormState`, `ConfirmDialog` | Not used | no `ftui_extras::forms` usage in `src/` |\n| `validation` | composable validators (`Required`, `MinLength`, `Email`, `ValidatorBuilder`) + async/deadline coordinators | Not used | no `ftui_extras::validation` usage in `src/` |\n| `help` | `Tooltip`, `Spotlight`, guided `Tour` state | Not used | no `ftui_extras::help` usage in `src/` |\n| `theme` | theme registry + semantic token helpers | Not used directly (cass uses its own style system) | no `ftui_extras::theme` usage in `src/` |\n| `syntax` | language tokenizers/highlighter APIs | Not used directly | no `ftui_extras::syntax` usage in `src/` |\n\n### Chart/canvas/FX detail inventory (requested deep scope)\n\n#### Charts (available)\n\n- Chart types: `Sparkline`, `BarChart`, `LineChart`.\n- Useful builder knobs currently available:\n  - `Sparkline`: `style`, `min`, `max`, `gradient`\n  - `BarChart`: direction (`Vertical`/`Horizontal`), mode (`Grouped`/`Stacked`), `bar_width`, `bar_gap`, `group_gap`, `colors`, bounds\n  - `LineChart`: bounds, labels, legend toggle, per-series markers\n\nCurrent cass usage:\n\n- Uses all three chart types, but in static render mode.\n- No chart widget-level hit test plumbing for direct click-to-drill; drilldown is list-row based.\n\n#### Canvas (available)\n\n- Modes: `Braille` (2x4), `Block` (2x2), `HalfBlock` (1x2).\n- Primitives: point, colored point, line, colored line, rect, filled rect, filled polygon, circle, metaball field rendering helper.\n\nCurrent cass usage:\n\n- Uses `Painter::for_area` + `point_colored` loops for heatmap block fills.\n- Does not use line/circle/polygon/metaball primitives yet.\n\n#### Visual FX (available)\n\n- Core: `FxQuality`, `ThemeInputs`, `BackdropFx`, `FxLayer`, `StackedFx`, scrim blending and quality clamping.\n- Exported effects: `MetaballsFx`, `PlasmaFx`, samplers, optional canvas adapters.\n- Infrastructure supports graceful degradation alignment with frame budget.\n\nCurrent cass usage:\n\n- No active usage in app rendering pipeline.\n- Existing app has its own stagger reveal hooks but no `ftui_extras::visual_fx` backdrop composition.\n\n## ftui widgets surface: available vs used\n\n`ftui-widgets` exposes 57 widget modules at this pinned rev.  \ncass directly imports a small subset in production UI:\n\n- `block`, `borders`, `command_palette`, `help_registry`, `hint_ranker`, `json_view`, `paragraph`, `focus`, `virtualized`, `inspector`\n\nObservation:\n\n- cass already uses advanced core widgets (command palette, hint ranker, virtualized list, inspector).\n- There is still unused headroom in core widgets (`table`, `progress`, `spinner`, `modal`, `toast`, etc.) that could simplify some custom rendering logic.\n\n## Prioritized gap analysis\n\n### High value gaps\n\n1. No direct chart interaction bridge (click/select point -> filtered search drilldown)\n- Impact: blocks a key goal in Feature B/C.\n- Best follow-up: `3nwtd.2.2`, then `3nwtd.3.2`.\n\n2. Canvas is underused for analytics beyond heatmap fill\n- Missing: scatter/area/shape-based renderings despite primitive support.\n- Best follow-up: `3nwtd.2.4`.\n\n3. `visual-fx` not integrated into surface transitions/loading polish\n- Missing: backdrop/scrim-based motion and composited transitions.\n- Best follow-up: `3nwtd.4.1`, `3nwtd.4.2`.\n\n### Medium value gaps\n\n1. `syntax` feature is enabled but not directly exercised by cass UI code\n- Markdown is rendered, but there is no explicit syntax highlighter integration path in cass-owned code.\n\n2. `help` tours/tooltips are unused\n- Could improve onboarding and discoverability of dense keyboard workflows.\n\n3. `forms` + `validation` are unused\n- Could standardize interactive config/filter dialogs and reduce hand-rolled validation logic.\n\n### Low value / opportunistic gaps\n\n1. `ftui_extras::theme` is unused directly\n- cass has robust custom style system already; migration benefit is incremental, not urgent.\n\n2. Export path could evolve from snapshot-only to richer share/report bundles\n- APIs already present (`HtmlExporter`, `SvgExporter`, `TextExporter`) and partially used.\n\n## Recommended execution sequence\n\n1. Land this audit (current bead).\n2. Implement interactive chart drilldown (`3nwtd.2.2`) with explicit selection model and query handoff contract.\n3. Add one canvas-native analytics panel (`3nwtd.2.4`) as a proof point (scatter + area fill).\n4. Integrate `visual-fx` backdrop transitions gated by degradation (`3nwtd.4.1`).\n5. Add loading states tied to async boundaries (`3nwtd.4.2`), using spinner/progress where practical.\n\n## Practical implementation notes for next beads\n\n- Keep `analytics_charts.rs` as the chart orchestration layer; route all drilldown intents through typed `CassMsg` events.\n- Reuse existing `selection` plumbing already present in analytics views before adding new input modes.\n- Wire any visual FX through quality gates (`FxQuality::from_degradation_with_area`) to preserve frame budget guarantees.\n- Prefer incremental view-level activation flags so new visuals can be A/B tested without destabilizing all analytics views at once.\n"

Markdown theme coherence and degradation policy are coupled; one can hide or amplify the other.\n2. Search/results visual improvements can mask style-token drift unless token-audit tests stay green.\n3. Snapshot-only coverage is insufficient without E2E logging context for failure triage.\n\n## Tradeoffs Taken in Rev 1\n1. Prioritized deterministic and reproducible captures over broad one-off screenshot collection.\n2. Published a partial scenario matrix now to unblock ownership, while explicitly tracking missing captures.\n3. Used existing ratatui-era screenshot assets for baseline continuity in this first bundle revision.\n\n## Remaining Work to Fully Complete `2dccg.1.2`\n1. Capture snippets-tab side-by-side artifact pair.\n2. Capture json-tab side-by-side artifact pair.\n3. Capture find-open side-by-side artifact pair.\n4. Add Light + HighContrast variants for the scenario set in the same manifest schema.\n5. Add final scored deltas using the rubric in `docs/ftui_visual_parity_rubric.md`.\n\n## How Future Agents Should Extend This Bundle\n1. Add files under `test-results/visual-parity/<date>/...`.\n2. Append scenario entries in `manifest.json` with explicit `status`.\n3. Keep scenario IDs stable; do not rename previously published IDs.\n4. Update this document’s matrix and residual-work section in the same commit.\n"

Reviewer A scores baseline and candidate.\n2. Reviewer B scores baseline and candidate.\n3. Compare per-category deltas and rationale text.\n4. If any category differs by >=2 points between reviewers:\n   - rerun scenario once with shared deterministic metadata\n   - reconcile to a final agreed score with explicit rationale notes\n\n## Scoring Worksheet Template\nCopy this table per scenario.\n\n| Scenario ID | Build | Hierarchy (25) | Affordance (20) | Theme (20) | Roles (15) | Density (20) | Weighted Total |\n|---|---|---:|---:|---:|---:|---:|---:|\n| `<id>` | ratatui-v0.1.64 |  |  |  |  |  |  |\n| `<id>` | ftui-current |  |  |  |  |  |  |\n\nRationale notes:\n- Hierarchy:\n- Affordance:\n- Theme:\n- Roles:\n- Density:\n\n## Worked Example (Representative Scenario)\nScenario ID: `S1-search-detail-find-open-wide`  \nConditions:\n- width/height: `160x50`\n- theme: `Dark`\n- degradation: `Full`\n- fixture: `high_fidelity_fixture_v1`\n- query: `\"theme mapping\"`\n- detail tab: `Messages`\n- find mode: open, current match `2/7`\n\n### Raw Scores\n| Category | Weight | ratatui raw | ftui raw |\n|---|---:|---:|---:|\n| Information hierarchy clarity | 25 | 4 | 2 |\n| Affordance discoverability | 20 | 4 | 2 |\n| Theme cohesion | 20 | 4 | 1 |\n| Role differentiation | 15 | 4 | 2 |\n| Density/readability | 20 | 4 | 3 |\n\n### Weighted Totals\n- ratatui total:\n  - `(4/5)*25 + (4/5)*20 + (4/5)*20 + (4/5)*15 + (4/5)*20`\n  - `20 + 16 + 16 + 12 + 16 = 80`\n- ftui total:\n  - `(2/5)*25 + (2/5)*20 + (1/5)*20 + (2/5)*15 + (3/5)*20`\n  - `10 + 8 + 4 + 6 + 12 = 40`\n\nInterpretation:\n- Candidate fails release threshold (`40 < 80`) and has category scores below `3`.\n- Primary deficits map to:\n  - Theme cohesion (markdown/themed rendering mismatch)\n  - Affordance discoverability (flat pills/tabs/find cues)\n  - Hierarchy clarity (reduced emphasis and structural contrast)\n\n## Mapping Rule (Rubric -> Workstream)\nWhen a category fails, map to owning tracks:\n- Hierarchy + Affordance: Tracks B, D, H, I\n- Theme cohesion: Tracks C, J\n- Role differentiation: Track B\n- Density/readability: Tracks F, I\n- Cross-theme/degradation stability: Tracks E, F, K\n\n## Change Control\nIf rubric weights or anchors change:\n- Update this document in the same PR\n- Include rationale and expected effect on pass/fail decisions\n- Re-score at least one representative scenario to show impact\n\n## 2dccg.1.2 Canonical Scenario Matrix\nThis section is the authoritative

Complete markdown theme parity hardening in Track C (`coding_agent_session_search-2dccg.3.1` to `coding_agent_session_search-2dccg.3.3`).\n2. Execute capability/degradation hardening in Track E/J to prevent environment-specific regressions.\n3. Feed captured artifacts into Track K evidence bundle (`coding_agent_session_search-2dccg.11.8`) before release unpin decisions.\n\n## 2dccg.1.5 Ratatui -> FTUI Capability Crosswalk\nStatus legend:\n- `kept`: behavior parity retained\n- `improved`: parity retained plus higher quality/usability\n- `replaced`: intentional behavior change (must document rationale)\n- `at_risk`: partially implemented or missing deterministic evidence\n\n| Capability | Ratatui v0.1.64 expectation | FTUI status | Evidence anchors | Owning beads |\n|---|---|---|---|---|\n| Search input cues + editing behavior | Query entry/editing is always discoverable and Enter submits deterministic search | improved | `src/ui/app.rs:14616`, `src/ui/app.rs:14877`, `tests/snapshots/cassapp_results_wide.snap` | `coding_agent_session_search-2dccg.8.1`, `coding_agent_session_search-2dccg.11.2` |\n| Filter pills (state, affordance, click targets) | Pills clearly indicate active filters and support interaction | improved | `src/ui/app.rs:4030`, `src/ui/app.rs:4077`, `src/ui/app.rs:17071`, `src/ui/app.rs:17093`, `src/ui/app.rs:4877`, `src/ui/app.rs:20964` | `coding_agent_session_search-2dccg.8.2`, `coding_agent_session_search-2dccg.8.3`, `coding_agent_session_search-2dccg.6.2`, `coding_agent_session_search-2xg36` |\n| Result list hierarchy (score/source/snippet) | Fast scan of score + provenance + snippet quality | improved | `tests/snapshots/cassapp_search_surface_breakpoint_medium.snap`, `tests/snapshots/cassapp_search_surface_breakpoint_narrow.snap`, `tests/snapshots/cassapp_search_surface_structure_default.snap`, `src/ui/app.rs:17375`, `src/ui/app.rs:17696`, `src/ui/app.rs:28270` | `coding_agent_session_search-2dccg.9.1`, `coding_agent_session_search-2dccg.9.2`, `coding_agent_session_search-2dccg.9.3`, `coding_agent_session_search-2dccg.9.5`, `coding_agent_session_search-m050g` |\n| Detail tabs + active-state clarity | Messages/Snippets/Raw/Json tabs remain explicit and keyboard navigable | improved | `src/ui/app.rs:4820`, `src/ui/app.rs:15549`, `src/ui/app.rs:15787` | `coding_agent_session_search-2dccg.2`, `coding_agent_session_search-2dccg.8.6`, `coding_agent_session_search-2dccg.11.2` |\n| Detail find bar + match counters + key flows | `/`, `n`, `N`, `Esc` flows remain reliable with visible match state | improved | `src/ui/app.rs:2870`, `src/ui/app.rs:17801`, `src/ui/app.rs:17934`, `tests/snapshots/cassapp_baseline_detail_find_current_match.snap` | `coding_agent_session_search-2dccg.4.1`, `coding_agent_session_search-2dccg.4.2`, `coding_agent_session_search-2dccg.4.3`, `coding_agent_session_search-1dkp4` |\n| Role differentiation + metadata readability | User/assistant/tool/system remain visually distinct with readable metadata | improved | `src/ui/app.rs:4256`, `src/ui/app.rs:4267`, `src/ui/app.rs:15860` | `coding_agent_session_search-2dccg.2`, `coding_agent_session_search-2dccg.9.3`, `coding_agent_session_search-2dccg.11.1` |\n| Footer HUD/status/degradation diagnostics | Status footer communicates mode, density, degradation, and guidance | improved | `src/ui/app.rs:3661`, `src/ui/app.rs:16317`, `src/ui/app.rs:16753` | `coding_agent_session_search-2dccg.8.5`, `coding_agent_session_search-2dccg.10.9`, `coding_agent_session_search-2dccg.11.6` |\n| Keyboard + mouse navigation affordances | Full keyboard coverage with mouse parity for common actions | improved | `src/ui/app.rs:19959`, `src/ui/app.rs:17144`, `src/ui/app.rs:17219`, `src/ui/app.rs:17841` | `coding_agent_session_search-2dccg.11.2`, `coding_agent_session_search-2dccg.9.5` |\n\n### Intentional Replacements\n- None declared yet.

    "content": "# CASS Indexing Historical Benchmark Results\n\n## Corpus\n- Date: 2026-04-17\n- Canonical DB: `/home/ubuntu/.local/share/coding-agent-search/agent_search.db`\n- Conversations: `51,185`\n- Messages: `4,703,804`\n- DB size: `22,396,870,656` bytes (`~20.86 GiB`)\n- Message content bytes: `1,938,100,433` bytes (`~1.80 GiB`)\n- Benchmark harness: `/tmp/cass_real_index_benchmark.py`\n- Benchmark command shape:\n\n```bash\ncass --db /home/ubuntu/.local/share/coding-agent-search/agent_search.db   index --json --force-rebuild --data-dir <fresh-temp-dir>\n```\n\n## Notes\n- All runs below used a fresh temporary `--data-dir`, so they measure a full lexical Tantivy rebuild from the canonical SQLite DB.\n- `--force-rebuild` on an already-populated canonical DB intentionally takes the canonical-only rebuild path.\n- The machine is shared, so CPU availability varies somewhat across runs. Repeated runs are recorded explicitly instead of relying on a single sample.\n- The later code-default runs used the source-built release binary at `/data/projects/coding_agent_session_search/target-optbench/release/cass`.\n\n## Results\n\n| Label | Code State | Wall s | Conv/s | Msg/s | DB MB/s | Avg Proc CPU % | Peak RSS GiB |\n|---|---|---:|---:|---:|---:|---:|---:|\n| `opt3-frankensearch8e07` | pinned `frankensearch` baseline after earlier rebuild-streaming fixes | 99.820 | 512.774 | 47122.951 | 213.979 | 778.495 | 20.804 |\n| `opt3-frankensearch8e07-singleopen` | single-open current-schema fast path | 93.718 | 546.161 | 50191.139 | 227.911 | 743.708 | 20.782 |\n| `opt3-frankensearch8e07-singleopen-addbatch16k` | single-open plus larger Tantivy add batches via env (`16384` messages / `64 MiB`) | 88.668 | 577.267 | 53049.762 | 240.892 | 990.834 | 21.579 |\n| `opt3-frankensearch8e07-singleopen-batchconv1024` | single-open plus larger outer conversation batch (`1024`) | 96.741 | 529.093 | 48622.639 | 220.789 | 910.474 | 21.011 |\n| `opt3-frankensearch8e07-singleopen-codedefault-addbatch` | single-open plus code-default parallelism-aware Tantivy add batches | 88.659 | 577.322 | 53054.771 | 240.914 | 994.472 | 21.592 |\n| `opt3-frankensearch8e07-singleopen-codedefault-addbatch-override32k` | code-default run plus `32768` messages / `128 MiB` override | 88.662 | 577.304 | 53053.151 | 240.907 | 1009.430 | 21.959 |\n\n## Phase Timing Breakdown\n\n### `opt3-frankensearch8e07`\n- preparing -> indexing: `24.718s`\n- indexing start -> `current=51185`: `56.041s`\n- phase reset after indexing: `82.160s`\n- completed payload emitted: `97.071s`\n- observed shutdown tail after phase reset: `14.911s`\n\n### `opt3-frankensearch8e07-singleopen`\n- preparing -> indexing: `23.917s`\n- indexing start -> `current=51185`: `52.036s`\n- phase reset after indexing: `76.754s`\n- completed payload emitted: `91.148s`\n- observed shutdown tail after phase reset: `14.394s`\n\n### `opt3-frankensearch8e07-singleopen-addbatch16k`\n- preparing -> indexing: `24.117s`\n- indexing start -> `current=51185`: `46.033s`\n- phase reset after indexing: `72.051s`\n- completed payload emitted: `86.062s`\n- observed shutdown tail after phase reset: `14.011s`\n\n### `opt3-frankensearch8e07-singleopen-batchconv1024`\n- preparing -> indexing: `24.017s`\n- indexing start -> `current=51185`: `54.039s`\n- phase reset after indexing: `80.057s`\n- completed payload emitted: `94.143s`\n- observed shutdown tail after phase reset: `14.086s`\n\n### `opt3-frankensearch8e07-singleopen-codedefault-addbatch`\n- preparing -> indexing: `24.216s`\n- indexing start -> `current=51185`: `46.034s`\n- phase reset after indexing: `72.352s`\n- completed payload emitted: `86.062s`\n- observed shutdown tail after phase reset: `13.710s`\n\n### `opt3-frankensearch8e07-singleopen-codedefault-addbatch-override32k`\n- preparing -> indexing: `24.116s`\n- indexing start -> `current=51185`: `46.033s`\n- phase reset after indexing: `72.350s`\n- completed payload emitted: `86.143s`\n- observed shutdown tail after phase reset: `13.793s`\n\n## Takeaways\n- The single-open storage fast path delivered a real win over the pinned baseline: `99.820s -> 93.718s` (`~6.1%` faster wall clock).\n- The bigger Tantivy add-batch lever delivered the next real win: `93.718s -> 88.659s` (`~5.4%` faster wall clock) once promoted from env-only tuning into code defaults.\n- The net improvement across this optimization cycle is `99.820s -> 88.659s` (`~11.2%` faster wall clock).\n- Enlarging the outer conversation batch to `1024` was a regression and should not be kept.\n- Pushing the Tantivy add-batch ceiling even higher (`32768` messages / `128 MiB`) produced no meaningful speedup and increased memory, so the smaller code-default setting is the better default.\n- Even at the current best run, the process is still not saturating the machine. Average process CPU was about `994%`, which is only about `9.9` fully busy cores on average.\n- The remaining dominant fixed costs are still the pre-index prepare phase (`~24.2s`) and the post-index shutdown tail (`~13.7s`).\n\n## Artifacts\n- `/tmp/cass-real-bench-20260417-opt3-frankensearch8e07/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-opt3-frankensearch8e07-singleopen/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-opt3-frankensearch8e07-singleopen-addbatch16k/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-opt3-frankensearch8e07-singleopen-batchconv1024/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-opt3-frankensearch8e07-singleopen-codedefault-addbatch/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-opt3-frankensearch8e07-singleopen-codedefault-addbatch-override32k/logs/summary.json`\n\n\n## Follow-up Cycle — Prepare/Shutdown Focus\n\n### Goal\n- Focus the next optimization pass on the serialized pre-index and post-index work around the streamed rebuild, then keep only changes that survive real full-corpus benchmarking.\n\n### Fresh-Eyes Fix\n- While re-reading the new code, one test bug turned up: `rebuild_tantivy_from_db_resume_reports_total_observed_messages` was asserting a nonexistent `checkpoint.total_messages` field. The test now loads the full lexical rebuild state and asserts `state.db.total_messages` instead.\n\n### Code Changes Kept\n- `src/main.rs`: apply a code-level default `CASS_TANTIVY_MAX_WRITER_THREADS=26` when the user has not explicitly configured it.\n- `src/search/tantivy.rs`: keep the same `26`-thread fallback in the writer parallelism heuristic so the in-process default and library fallback stay aligned.\n- `src/indexer/mod.rs`: keep the fresh-eyes test fix only. A more invasive writer-storage reopen experiment was benchmarked and rejected.\n\n### Follow-up Results\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Avg Proc CPU % | Peak RSS GiB | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---|\n| `r7-reopenstorage` | close and reopen writer storage around authoritative rebuild | 83.664 | 611.796 | 56222.878 | 255.300 | 1058.284 | 20.597 | rejected |\n| `r8-rebaseline` | rebaseline after reverting the reopen experiment | 81.677 | 626.679 | 57590.626 | 261.511 | 1114.162 | 21.572 | baseline |\n| `r9-writer24` | env override `CASS_TANTIVY_MAX_WRITER_THREADS=24` | 78.618 | 651.055 | 59830.755 | 271.683 | 825.335 | 20.522 | improved |\n| `r10-writer20` | env override `CASS_TANTIVY_MAX_WRITER_THREADS=20` | 119.056 | 429.925 | 39509.276 | 179.406 | 685.558 | 20.377 | rejected |\n| `r11-writer28` | env override `CASS_TANTIVY_MAX_WRITER_THREADS=28` | 76.588 | 668.314 | 61416.743 | 278.885 | 1066.166 | 21.062 | improved |\n| `r12-writer30` | env override `CASS_TANTIVY_MAX_WRITER_THREADS=30` | 80.630 | 634.814 | 58338.211 | 264.906 | 831.660 | 21.633 | rejected |\n| `r13-writer26` | env override `CASS_TANTIVY_MAX_WRITER_THREADS=26` | 76.574 | 668.438 | 61428.135 | 278.937 | 1038.264 | 21.105 | improved |\n| `r14-default26` | code-default `26` writer threads, no env override | 75.557 | 677.440 | 62255.422 | 282.693 | 1031.633 | 21.102 | accepted best |\n| `r15-default26-repeat` | repeat of code-default `26` writer threads | 76.561 | 668.550 | 61438.517 | 278.984 | 1027.329 | 20.997 | accepted repeat |\n\n### Follow-up Phase Breakdown\n\n| Label | Prepare s | Index Window s | Post-Index Tail s |\n|---|---:|---:|---:|\n| `r8-rebaseline` | 24.619 | 52.642 | 0.801 |\n| `r9-writer24` | 25.720 | 49.737 | 0.603 |\n| `r11-writer28` | 24.317 | 49.636 | 0.100 |\n| `r13-writer26` | 24.117 | 49.735 | 0.200 |\n| `r14-default26` | 24.016 | 48.735 | 0.300 |\n| `r15-default26-repeat` | 24.017 | 49.235 | 0.915 |\n\n### Follow-up Takeaways\n- The earlier exact-checkpoint work already collapsed the authoritative rebuild shutdown tail from double-digit seconds to sub-second territory. There was no hidden remaining post-index bug to unlock.\n- The reopen-storage experiment looked plausible on paper but was a real regression and should stay reverted.\n- The only clean win from this pass was retuning Tantivy writer parallelism. On this machine and corpus, `26` writer threads consistently beat the previous effective `32`-thread default.\n- The accepted code-default run improved wall clock from the rebaseline `81.677s` to `75.557s` (`~7.5%` faster in this pass) and from the previous documented best `88.659s` to `75.557s` (`~14.8%` faster overall).\n- The dominant remaining fixed cost is still the prepare leg at about `24.0s`. The index-window work is now under `50s`, and the shutdown tail is no longer the problem.\n- Even after the latest tuning, the process is still far from saturating a 128-core host. Average process CPU in the accepted runs was about `1030%`, or roughly `10.3` fully busy cores.\n\n### Follow-up Artifacts\n- `/tmp/cass-real-bench-20260417-r7-reopenstorage/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-r8-rebaseline/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-r9-writer24/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-r10-writer20/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-r11-writer28/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-r12-writer30/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-r13-writer26/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-r14-default26/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-r15-default26-repeat/logs/summary.json`\n\n\n## Prepare-Phase Optimization Cycle\n\n### Goal\n- Eliminate the remaining `~24s` serialized prepare cost in the canonical-only `--force-rebuild` path without changing the final lexical checkpoint contract.\n\n### Measured Rounds\n1. Replaced the combined `MAX(id)` fingerprint query with `ORDER BY id DESC LIMIT 1` subqueries. No measurable startup win.\n2. Added prep-stage instrumentation around DB-state construction. This proved path normalization was effectively free.\n3. Split the lexical content fingerprint into separate `conversations` and `messages` queries. Result: `conversations` took `~0.8s`, while `messages` consumed the remaining `~40s` startup stall.\n4. Accepted code change: canonical-only fresh-start rebuilds now defer the expensive initial `messages` fingerprint instead of blocking startup on it, while still persisting the exact final `content-v1` fingerprint synthesized from the streamed rebuild observations.\n5. Verified the change with a fresh release-build full-corpus benchmark on the real canonical DB.\n\n### Code Changes Kept\n- `src/indexer/mod.rs`\n  - Added a deferred-startup fingerprint mode for canonical-only fresh-start rebuilds.\n  - Fresh-start rebuilds now skip the blocking initial `messages` high-water fingerprint query during prepare.\n  - The completed lexical checkpoint still lands with the exact `content-v1:{total_conversations}:{max_conversation_id}:{max_message_id}` fingerprint by deriving the max IDs from the authoritative streamed rebuild itself.\n  - Added a regression test proving the deferred-startup path still persists the exact completed fingerprint.\n\n### Result\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Avg Proc CPU % | Peak RSS GiB | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---|\n| `r16-deferred-startup-fingerprint` | defer initial canonical-only force-rebuild content fingerprint; persist exact completed fingerprint from streamed observations | 71.645 | 714.429 | 65654.627 | 298.129 | 1085.203 | 20.888 | accepted |\n\n### Phase Breakdown\n\n| Label | Prepare s | Index Window s | Post-Index Tail s |\n|---|---:|---:|---:|\n| `r16-deferred-startup-fingerprint` | 0.600 | 66.047 | 1.397 |\n\n### Takeaways\n- The prepare-phase bottleneck was real and specific: the `messages` side of the lexical content fingerprint was consuming roughly `40s` before indexing even began.\n- Deferring that work on the explicit fresh-start canonical-only rebuild path collapsed prepare time from about `24.0s` to about `0.6s` in the real release benchmark.\n- Overall wall clock improved from the previous accepted best `75.557s` to `71.645s` (`~5.2%` faster overall on the same corpus and harness).\n- The final completed checkpoint contract was preserved. The optimization changes startup behavior, not the settled lexical checkpoint semantics.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260417-r16-deferred-startup-fingerprint/logs/summary.json`\n- `/tmp/cass-real-bench-20260417-r16-deferred-startup-fingerprint/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260417-r16-deferred-startup-fingerprint/logs/index.stdout.json`\n\n\n## Profile-Guided Commit-Cadence Optimization Cycle\n\n### Goal\n- Use explicit rebuild-stage telemetry to find the dominant remaining service center in the canonical-only force-rebuild path, then retune that lever without regressing correctness.\n\n### Alien-Artifact Framing\n- Treat the streamed lexical rebuild as a tandem queue. Measure each service center directly before tuning thresholds.\n- Use cliff detection rather than monotonicity assumptions: a larger checkpoint interval should help until segment merge or writer flush costs cross a threshold, then it will sharply regress.\n\n### Code Changes Kept\n- `src/indexer/mod.rs`\n  - Added opt-in rebuild-stage telemetry behind `CASS_TANTIVY_REBUILD_PROFILE`.\n  - The profiler records flush count, commit count, heartbeat persists, and cumulative prepare/add/commit/progress durations, then emits a single `CASS_REBUILD_PROFILE ...` summary line on stderr.\n  - Raised the steady-state lexical rebuild commit threshold from `200_000` messages to `800_000` messages.\n  - Raised the initial lexical rebuild message threshold from `50_000` to `800_000` messages because the initial slice is already bounded by conversation and byte ceilings.\n  - Reworked the streamed conversation closure lifetime into a lexical scope so strict clippy stays clean without any artificial `drop(...)` hack.\n  - Updated the interval tests to match the new accepted default.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Commits | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---|\n| `r17-profile-baseline` | profiling on; prior code-default commit cadence | 77.712 | 658.652 | 60528.875 | 274.853 | 25 | 13798.996 | baseline |\n| `r18-commit400k` | env override `CASS_TANTIVY_REBUILD_COMMIT_EVERY_MESSAGES=400000` | 71.674 | 714.140 | 65628.100 | 298.008 | 13 | 7991.407 | improved |\n| `r19-commit800k` | env override `CASS_TANTIVY_REBUILD_COMMIT_EVERY_MESSAGES=800000` | 70.748 | 723.482 | 66486.597 | 301.906 | 8 | 6857.534 | improved |\n| `r20-commit1200k` | env override `CASS_TANTIVY_REBUILD_COMMIT_EVERY_MESSAGES=1200000` | 95.824 | 534.159 | 49088.192 | 222.903 | 7 | 25784.196 | rejected cliff |\n| `r21-commit800k-initial800k` | env override `800000` for steady and initial message thresholds | 68.648 | 745.620 | 68521.021 | 311.144 | 8 | 6866.053 | best env-only |\n| `r22-commit800k-initmsg800k-initconv10k` | also raise initial conversation threshold to `10000` | 69.642 | 734.977 | 67543.018 | 306.703 | 8 | 7310.640 | rejected |\n| `r23-default800k` | code-default `800000` steady and initial message thresholds, no env override | 69.650 | 734.890 | 67535.035 | 306.667 | 8 | 6845.780 | accepted |\n\n### Accepted Profile Breakdown\n\n| Label | Flushes | Heartbeat Persists | Prepare ms | Add ms | Commit ms | Pending Progress ms | Heartbeat Progress ms | Checkpoint Persist ms | Meta Fingerprint ms |\n|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|\n| `r23-default800k` | 105 | 21 | 10674.415 | 10474.053 | 6845.780 | 28.714 | 46.044 | 11.613 | 0.355 |\n\n### Takeaways\n- The new profiler made the next lever obvious: commit fences were still the biggest remaining serialized service center after the earlier prepare/startup fixes.\n- Raising the commit cadence from the old default to `800k` messages cut commit overhead from `~13.8s` in the profiled baseline to `~6.85s` in the accepted code-default run.\n- There is a real cliff. Pushing to `1.2M` messages looked attractive on paper but detonated commit cost to `~25.8s` and regressed wall clock badly.\n- The accepted code-default run improved wall clock from the previous accepted best `71.645s` to `69.650s` (`~2.8%` faster overall).\n- Relative to this cycle's measured profiled baseline, the accepted code-default run improved wall clock from `77.712s` to `69.650s` (`~10.4%` faster).\n- On the accepted run, the remaining measured service centers are still substantial: prepare `~10.7s`, add `~10.5s`, commit `~6.85s`.\n- The next plausible frontier is no longer commit cadence. It is the unmeasured stream-assembly path between ordered DB rows and prepared Tantivy batches, plus any remaining per-batch preparation overhead hidden inside the `prepare` bucket.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260418-r17-profile-baseline/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r17-profile-baseline/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r18-commit400k/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r18-commit400k/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r19-commit800k/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r19-commit800k/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r20-commit1200k/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r20-commit1200k/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r21-commit800k-initial800k/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r21-commit800k-initial800k/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r22-commit800k-initmsg800k-initconv10k/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r22-commit800k-initmsg800k-initconv10k/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r23-default800k/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r23-default800k/logs/index.stderr.log`\n\n\n\n## Debug Current-Tree Queue-Geometry Rejection Cycle\n\n### Goal\n- Re-test the suspected stream-assembly bottleneck on the live corpus using a current-tree debug binary fetched from a warm remote worker, then separate real wins from deceptive mid-run progress improvements.\n\n### Environment Notes\n- These rounds used `/tmp/cass-remote-debug`, a current-tree debug binary built remotely on `ts2` and copied back with `scp`.\n- A full optimized remote build was also started, but it remained in cold dependency compilation long enough that it stopped being the critical path for this cycle.\n- Because these are debug-binary measurements, use them to rank local hypotheses, not to replace the accepted release-profile history above.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Outcome |\n|---|---|---:|---:|---:|---:|---|\n| `r31-batch256-debug` | env override `CASS_TANTIVY_REBUILD_BATCH_FETCH_CONVERSATIONS=256` | 486.567 | 105.196 | 9666.912 | 44.074 | baseline for outer-batch sweep |\n| `r32-batch384-debug` | env override `CASS_TANTIVY_REBUILD_BATCH_FETCH_CONVERSATIONS=384` | 481.607 | 106.280 | 9766.487 | 44.528 | best in initial debug outer-batch sweep |\n| `r33-batch512-debug` | env override `CASS_TANTIVY_REBUILD_BATCH_FETCH_CONVERSATIONS=512` | 486.576 | 105.194 | 9666.740 | 44.073 | rejected |\n| `r35-patched-default-debug` | experimental shard-flatten removal in streamed rebuild path; default queue settings | 488.574 | 104.764 | 9627.619 | 43.718 | rejected |\n| `r36-patched-batch384-debug` | shard-flatten removal plus `batch_fetch_conversations=384` | 497.716 | 102.840 | 9450.773 | 42.915 | rejected |\n| `r37-inner8192-32m-debug` | reverted code path; smaller inner Tantivy add batches via `CASS_TANTIVY_ADD_BATCH_MAX_MESSAGES=8192` and `CASS_TANTIVY_ADD_BATCH_MAX_CHARS=33554432` | 496.674 | 103.055 | 9470.603 | 43.005 | rejected |\n\n### Profile Highlights\n\n| Label | Flushes | Commits | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---:|---:|---:|---:|---:|---|\n| `r31-batch256-debug` | 205 | 8 | 43024.856 | 41193.042 | 71299.504 | baseline |\n| `r32-batch384-debug` | 140 | 8 | 42326.307 | 40683.233 | 69395.433 | best initial sweep |\n| `r33-batch512-debug` | 105 | 8 | 39905.467 | 38428.934 | 73655.906 | rejected |\n| `r35-patched-default-debug` | 105 | 8 | 39479.486 | 38680.342 | 73528.180 | rejected |\n| `r36-patched-batch384-debug` | 140 | 8 | 42291.806 | 41356.877 | 69321.667 | rejected |\n| `r37-inner8192-32m-debug` | 105 | 8 | 54022.954 | 53226.469 | 66625.334 | rejected |\n\n### Takeaways\n- The outer-batch sweep alone was real but small: `384` conversations per outer chunk beat `256` and `512`, but only by about `1.0%` in this debug matrix. That is not the kind of leverage that justifies large code churn by itself.\n- The streamed shard-flatten removal was a deceptive non-win. It made some mid-run progress windows look faster, but end-to-end wall clock stayed flat or regressed. The change was reverted.\n- Shrinking the inner Tantivy add-batch amplitude reduced peak RSS slightly and trimmed commit time, but it exploded prepare/add overhead badly enough to lose overall.\n- The long flat spots in progress are still present after these queue-geometry variants. That keeps the dominant suspicion on Tantivy-side commit/segment behavior, not on one extra user-space flatten or on simply making batches smaller.\n- The best result in this cycle remains `r32-batch384-debug`, and even that is only a modest improvement over the surrounding debug variants. No new code-default optimization was accepted from this cycle.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260418-r31-batch256-debug/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r31-batch256-debug/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r32-batch384-debug/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r32-batch384-debug/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r33-batch512-debug/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r33-batch512-debug/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r35-patched-default-debug/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r35-patched-default-debug/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r36-patched-batch384-debug/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r36-patched-batch384-debug/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r37-inner8192-32m-debug/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r37-inner8192-32m-debug/logs/index.stderr.log`\n\n\n## Local-Override Lexical Writer Control And Rejection Cycle\n\n### Goal\n- Re-check the real lexical writer bottleneck with a clean, optimized profiling binary and use that tighter control to test the remaining high-EV levers: merge suppression, writer-thread count, relaxed early commit fencing, and the one outer batch size that had shown a weak positive hint.\n\n### Environment Notes\n- `Cargo.toml` already pins `frankensearch` rev `8e07d082`, and the local checkout used for the temporary override was at the same `HEAD`.\n- The local override was only used to make it easy to benchmark a temporary `no_merge` experiment and to build a fresh profiling binary on `ts2`.\n- The accepted control run below is therefore behaviorally equivalent to the current effective dependency path. The temporary `no_merge` knob was later reverted from the sibling `frankensearch` checkout.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Flushes | Commits | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r38-localfs-default-debug` | local override debug control | 503.834 | 101.591 | 9336.013 | 42.394 | 105 | 8 | 40665.826 | 39869.950 | 75391.760 | baseline for override cycle |\n| `r39-localfs-no-merge-debug` | temporary `CASS_TANTIVY_DISABLE_BULK_LOAD_MERGES=1` | 515.105 | 99.368 | 9131.745 | 41.466 | 105 | 8 | 40923.727 | 40124.853 | 81082.569 | rejected |\n| `r40-localfs-w16-debug` | `CASS_TANTIVY_MAX_WRITER_THREADS=16` | 580.127 | 88.231 | 8108.235 | 36.818 | 105 | 8 | 52056.020 | 51258.220 | 144175.618 | rejected hard |\n| `r41-localfs-default-profiling` | fresh optimized profiling control | 63.582 | 805.025 | 73980.243 | 335.934 | 105 | 8 | 7494.415 | 7221.018 | 7186.305 | accepted fresh best |\n| `r42-localfs-w20-profiling` | `CASS_TANTIVY_MAX_WRITER_THREADS=20` | 67.632 | 756.814 | 69549.805 | 315.816 | 105 | 8 | 9002.267 | 8701.574 | 7136.817 | rejected |\n| `r43-localfs-w32-profiling` | `CASS_TANTIVY_MAX_WRITER_THREADS=32` | 68.693 | 745.131 | 68476.142 | 310.941 | 105 | 8 | 8079.636 | 7770.994 | 7171.754 | rejected |\n| `r44-localfs-commit1m-profiling` | relax initial fence and raise message commit target to `1_000_000` | 67.637 | 756.760 | 69544.827 | 315.793 | 104 | 6 | 7848.833 | 7564.444 | 8795.677 | rejected |\n| `r45-localfs-batch384-profiling` | `CASS_TANTIVY_REBUILD_BATCH_FETCH_CONVERSATIONS=384` | 66.635 | 768.136 | 70590.234 | 320.540 | 140 | 8 | 8218.176 | 7856.156 | 7337.777 | rejected |\n\n### Accepted Control Breakdown\n\n| Label | Flushes | Heartbeat Persists | Prepare ms | Add ms | Commit ms | Pending Progress ms | Heartbeat Progress ms | Checkpoint Persist ms | Meta Fingerprint ms |\n|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|\n| `r41-localfs-default-profiling` | 105 | 21 | 7494.415 | 7221.018 | 7186.305 | 24.703 | 50.732 | 13.898 | 0.367 |\n\n### Takeaways\n- The strongest new datum in this cycle is the fresh optimized control itself: `r41-localfs-default-profiling` completed in `63.582s`, materially faster than the prior documented best `69.650s` (`~8.7%` faster).\n- Suppressing bulk-load merges entirely was a clean loser. `r39` increased commit cost from `75.392s` to `81.083s` in the debug matrix, so the problem is not “too many merges, just turn them off.”\n- Lowering writer threads was also a loser. `r42` and especially `r40` showed that reducing writer parallelism hurt `prepare` and `add` much more than it helped `commit`.\n- Raising writer threads to `32` was also worse than the control. `r43` kept commit cost roughly flat while regressing both `prepare` and `add`, which implies the current default writer-thread cap is already close to the local optimum.\n- Relaxing the initial restartability fence did reduce commit count (`8 -> 6` in `r44`), but it still lost overall because per-commit cost rose sharply and the larger slices made `prepare`/`add` worse. “Fewer commits” is not the objective function by itself.\n- Re-testing the old outer-batch `384` hint on the optimized control binary also lost. It increased flush count from `105` to `140` and regressed wall clock despite a superficially good debug hint earlier.\n- No new code-default optimization was accepted from this cycle. The only durable artifact kept in this repo is the benchmark history update documenting the new control and the rejected levers around it.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260418-r38-localfs-default-debug/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r38-localfs-default-debug/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r39-localfs-no-merge-debug/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r39-localfs-no-merge-debug/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r40-localfs-w16-debug/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r40-localfs-w16-debug/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r41-localfs-default-profiling/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r41-localfs-default-profiling/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r42-localfs-w20-profiling/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r42-localfs-w20-profiling/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r43-localfs-w32-profiling/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r43-localfs-w32-profiling/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r44-localfs-commit1m-profiling/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r44-localfs-commit1m-profiling/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r45-localfs-batch384-profiling/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r45-localfs-batch384-profiling/logs/index.stderr.log`\n\n## Streamed Rebuild Queueing Experiments: Rejected\n\n### Goal\n- Test whether removing the outer flattened-doc materialization, and then overlapping prepare with add via a bounded ordered pipeline, could reduce the effective `prepare + add` portion of lexical rebuild without hurting commit behavior.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---|\n| `r46-localdebug-pipeline` | shard streaming plus bounded ordered prepare→add pipeline, debug | 499.811 | 102.409 | 9411.169 | 42.735 | 917.130 | 39825.243 | 73981.459 | rejected |\n| `r47-profiling-pipeline` | same bounded ordered pipeline, optimized profiling build | 63.582 | 805.020 | 73979.837 | 335.932 | 382.818 | 7386.208 | 7066.819 | rejected as benchmark-neutral |\n| `r48-profiling-shardstream` | shard streaming only, no pipeline, optimized profiling build | 63.587 | 804.962 | 73974.492 | 335.908 | 407.439 | 7414.252 | 7057.664 | rejected as slightly slower |\n\n### Takeaways\n- The bounded ordered pipeline did exactly what the internal counters said it would do: it nearly eliminated standalone `prepare_ms`. That did **not** translate into end-to-end wall-clock improvement on the real corpus.\n- On the trusted profiling run, the pipeline path (`r47`) ended effectively tied with the standing best control (`r41-localfs-default-profiling` at `63.582s`). The saved prepare time simply reappeared inside the broader add/consumer critical path.\n- The debug run for the same pipeline path (`r46`) was a clearer loser at `499.811s` versus the prior nearby debug point `481.607s`, confirming that the more complex queueing path was not a robust improvement.\n- The simpler shard-streaming-only variant (`r48`) was also not good enough. It landed at `63.587s`, fractionally slower than the standing best control, so the extra hot-path complexity was not justified.\n- Final decision from this cycle: revert both experiments. The repo should not keep either the bounded ordered pipeline or the shard-streaming-only hot-path change based on this evidence.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260418-r46-localdebug-pipeline/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r46-localdebug-pipeline/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r47-profiling-pipeline/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r47-profiling-pipeline/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r48-profiling-shardstream/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r48-profiling-shardstream/logs/index.stderr.log`\n\n\n## Rebuild Scan-Path Breakdown And Grouped Message Streaming\n\n### Goal\n- Measure the previously unaccounted lexical rebuild wall time inside the post-`ready_to_index` scan path, then attack the real hotspot instead of continuing speculative queue-shape experiments.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Total ms | Conversation List ms | Message Stream ms | Finish Conversation ms | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r49-prep-scan-control` | control run with new internal prep + rebuild breakdown enabled | 64.604 | 792.289 | 72809.885 | 330.620 | 60512.503 | 309.320 | 58307.003 | 14969.626 | 7635.771 | 7350.405 | 6382.053 | diagnostic baseline |\n| `r50-profile-scan-breakdown` | same control on current-tree profiling binary with retained scan timers | 64.597 | 792.379 | 72818.079 | 330.657 | 60512.503 | 309.320 | 58307.003 | 14969.626 | 8202.398 | 7016.905 | 7201.437 | confirms hotspot location |\n| `r51-grouped-message-stream` | storage streams one callback per conversation instead of one per message row | 63.565 | 805.234 | 73999.505 | 336.021 | 60219.208 | 315.846 | 58084.419 | 15053.749 | 8180.393 | 7029.454 | 7339.476 | accepted |\n| `r52-grouped-plus-move` | consume preloaded conversation rows via iterator instead of cloning each envelope | 63.574 | 805.131 | 73990.004 | 335.978 | 59920.119 | 318.789 | 57818.331 | 14710.652 | 7948.957 | 6828.904 | 7198.409 | retained, effectively tied |\n| `r53-grouped-plus-move-repeat` | repeat of retained current tree | 63.588 | 804.948 | 73973.232 | 335.902 | 59714.698 | 312.742 | 57637.359 | 14639.930 | 7908.375 | 6825.523 | 7055.011 | repeat confirms tie-stable behavior |\n\n### Takeaways\n- The earlier external “prepare” bucket was misleading. Internal prep before `ready_to_index` is only about `0.4s`; the real fixed cost was the scan path after startup.\n- The dominant hotspot was not conversation listing. `conversation_list_ms` stayed around `0.31s`, so materializing the conversation envelope vector was never the main problem.\n- The real cost center was the message scan/merge window itself: roughly `58.3s` on the control run. That made the highest-EV lever clear: cut outer per-message callback and merge overhead.\n- Grouped message streaming did that. `r51` improved wall clock from `64.597s` to `63.565s`, about `1.6%` faster, while also increasing throughput to about `74.0k` messages/sec.\n- The follow-on move-based conversation iterator was basically wall-clock neutral versus grouped-only, but it did reduce the internal scan and finish counters slightly on both retained samples. The current tree keeps it because it removes pointless conversation-envelope clone churn without evidence of regression.\n- The core scan path is still the frontier. Even after the accepted grouped-stream change, `message_stream_ms` is still about `57.6-58.1s`, which remains much larger than `prepare + add + commit`.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260418-r49-prep-scan-control/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r49-prep-scan-control/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r50-profile-scan-breakdown/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r50-profile-scan-breakdown/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r51-grouped-message-stream/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r51-grouped-message-stream/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r52-grouped-plus-move/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r52-grouped-plus-move/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r53-grouped-plus-move-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r53-grouped-plus-move-repeat/logs/index.stderr.log`\n\n## Grouped Stream Late-Materialization Sweep\n\n### Goal\n- Continue attacking the measured `message_stream_ms` hotspot inside the authoritative canonical-DB lexical rebuild by stripping per-row work that the grouped scan path did not actually need.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Total ms | Conversation List ms | Message Stream ms | Finish Conversation ms | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r55-precompute-message-bytes` | precompute message-byte totals during grouped scan and pass them into `finish_conversation` | 64.628 | 791.992 | 72782.587 | 330.496 | 60521.117 | 296.913 | 58495.152 | 15302.675 | 8567.230 | 7448.500 | 7058.829 | rejected |\n| `r56-grouped-null-author` | grouped scan projects `NULL AS author` instead of decoding unused author text | 63.593 | 804.885 | 73967.407 | 335.876 | 60051.317 | 311.745 | 58010.494 | 14689.677 | 8109.158 | 6959.775 | 6846.188 | effectively neutral |\n| `r57-grouped-lite-row` | grouped scan emits a lite row (`idx`, `created_at`, `content`, tool-bit) plus per-conversation last message id | 62.586 | 817.830 | 75157.021 | 341.278 | 58814.138 | 307.244 | 56816.733 | 14415.829 | 7660.826 | 6557.957 | 7170.979 | accepted fresh best |\n\n### Takeaways\n- Moving the message-byte summation earlier was a clean loser. `r55` regressed wall clock and worsened every important internal bucket (`message_stream`, `prepare`, and `add`). That lever was reverted.\n- Simply pruning grouped `author` decode was too small to matter by itself. `r56` landed essentially tied with the retained grouped-stream baseline, so it was only useful as a proof that narrow projection pruning in this area is behaviorally safe.\n- The stronger late-materialization lever did pay off. `r57` cut wall time to `62.586s`, improving on the prior retained `r53` repeat (`63.588s`) by about `1.6%`.\n- The accepted win is visible in the right internal buckets: `message_stream_ms` dropped from `57637.359` on `r53` to `56816.733` on `r57`, while `prepare_ms` and `add_ms` also improved materially.\n- The canonical corpus currently has zero `tool` rows (`SELECT count(*) FROM messages WHERE role='tool'` returned `0`), which made it especially clear that carrying full role strings through this grouped rebuild path was unnecessary overhead on this workload.\n- After `r57`, the dominant remaining cost is still the raw grouped scan and content transfer itself. The next frontier is likely the unavoidable `content` payload movement, not another tiny metadata field.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260418-r55-precompute-message-bytes/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r55-precompute-message-bytes/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r56-grouped-null-author/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r56-grouped-null-author/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r57-grouped-lite-row/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r57-grouped-lite-row/logs/index.stderr.log`\n\n\n## Corrected Runner Harness + Micro-Lever Sweep\n\n### Goal\n- Remove the full-CLI link step from the optimization loop without changing the authoritative indexer code path, then re-test two micro-levers on the real canonical corpus with a same-harness control.\n\n### Harness Notes\n- A tiny `/tmp/cass_runner_r59` wrapper was compiled directly against the freshly built `coding_agent_search` profiling rlib with `panic=abort`.\n- The first wrapper attempt was invalid because it omitted the normal `IndexingProgress`, which forced a slow final lexical fingerprint refresh (`fingerprint_messages step_ms=12887`). That measurement is retained only as a harness-debug artifact and is not used for decision-making.\n- The corrected runner uses `IndexingProgress::default()` so it matches the normal `cass index --force-rebuild` fast path closely enough for same-harness comparisons.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Rebuild ms | Message Stream ms | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r58-exact-flatten` | replace flattened-doc `collect()` with exact-capacity append | 64.589 | 792.466 | 72826.152 | 330.693 | 60.486 | 58.328 | 7.623 | 6.658 | 7.269 | rejected |\n| `r59-grouped-reserve64-invalid` | fixed grouped-message reserve of `64` on the first wrapper harness | 72.479 | 706.203 | 64898.708 | 294.696 | 54.819 | 52.781 | 7.982 | 6.842 | 7.139 | invalid harness; wrapper paid final fingerprint tail |\n| `r60-grouped-reserve64-corrected` | same reserve `64`, corrected wrapper harness | 59.431 | 861.247 | 79146.927 | 359.395 | 55.692 | 53.624 | 8.040 | 6.829 | 7.118 | tied / not a real win |\n| `r61-noise-fast-reject` | skip lowercase work for messages already rejected by the existing `>200` ack cutoff | 59.421 | 861.390 | 79160.104 | 359.455 | 55.829 | 53.800 | 8.011 | 6.809 | 7.030 | effectively neutral, kept as harmless cleanup |\n| `r62-corrected-control-noreserve` | corrected wrapper harness control with reserve removed, fast-reject still present | 59.436 | 861.184 | 79141.168 | 359.369 | 55.589 | 53.561 | 7.918 | 6.873 | 6.940 | control for reserve verdict |\n\n### Takeaways\n- The exact-capacity flattened-doc append looked plausible but was a clean loser on the real corpus and was reverted.\n- The first wrapper harness run surfaced an important control-plane issue: omitting `IndexingProgress` from the standalone runner disabled the existing fast-path that skips final lexical checkpoint refresh, which injected a bogus `~12.9s` fingerprint tail into wall clock.\n- Once the harness was corrected, the grouped reserve experiment collapsed to noise. `r60` and `r62` are effectively identical, so the reserve change was reverted.\n- The long-message fast-reject before lowercase is also basically noise on end-to-end wall time, but it is behavior-preserving and directionally sensible because it avoids useless lowercase allocation for messages that the existing rule would reject immediately anyway.\n- The corrected same-harness plateau is now about `59.42-59.44s`, which is materially faster than the older `62.586s` CLI-binary result, but this cycle should still be treated mainly as a harness-corrected micro-lever sweep rather than a big architectural breakthrough.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260418-r58-exact-flatten/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r58-exact-flatten/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r59-grouped-reserve64/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r59-grouped-reserve64/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r60-grouped-reserve64-corrected/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r60-grouped-reserve64-corrected/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r61-noise-fast-reject/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r61-noise-fast-reject/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r62-corrected-control-noreserve/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r62-corrected-control-noreserve/logs/index.stderr.log`\n\n\n## SmallVec Grouped-Stream Capacity Sweep\n\n### Goal\n- Attack the still-dominant grouped message-stream hot path by removing heap-first allocation for the common case: many conversations are small, so the grouped row buffer should start stack-first and spill only when needed.\n\n### Alien/Queueing Framing\n- This is a small-object allocation optimization, not a batching change. The queueing model stays the same; only the per-conversation buffer representation changes.\n- With median conversation size `38`, p90 `194`, p95 `379`, and p99 `1029`, a spillable inline buffer should capture a large fraction of conversations without paying the struct-bloat cost of a very large inline capacity.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Rebuild ms | Message Stream ms | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r63-smallvec48` | grouped message rows stored in `SmallVec<[row; 48]>` | 58.430 | 876.000 | 80502.742 | 365.552 | 55.271 | 53.163 | 8.014 | 6.876 | 7.103 | accepted candidate |\n| `r64-smallvec64` | widen inline capacity to `64` | 58.418 | 876.187 | 80519.918 | 365.630 | 54.386 | 52.313 | 7.739 | 6.597 | 6.970 | plateau / tied |\n| `r65-smallvec32` | shrink inline capacity to `32` | 58.417 | 876.194 | 80520.544 | 365.633 | 54.456 | 52.312 | 7.832 | 6.650 | 6.911 | plateau / retained best-by-size |\n| `r66-smallvec16` | shrink inline capacity further to `16` | 60.457 | 846.629 | 77803.579 | 353.295 | 56.311 | 54.086 | 8.065 | 6.869 | 7.008 | rejected |\n\n### Takeaways\n- `SmallVec` itself is the real win. Moving from the old heap-first grouped buffer path (`r62` corrected control at `59.436s`) to the stack-first path cut wall time by about `1.0s`, roughly `1.7%`.\n- The gain is visible in the right service center: `message_stream_ms` fell from `53665.752` on the corrected no-`SmallVec` control to about `52312-53163` on the `SmallVec` variants, with `prepare`, `add`, and `commit` also trending down.\n- The inline-capacity sweep found a flat optimum band rather than a sharp point. `32`, `48`, and `64` all beat the old control; `32` and `64` are essentially tied on wall time.\n- Pushing the inline buffer below that band breaks the win. `r66-smallvec16` regressed sharply to `60.457s`, so the common-case stack capture needs more than `16` inline slots on this corpus.\n- The retained setting should therefore bias toward the smaller inline footprint on the plateau. `32` keeps the common-case stack win while minimizing per-conversation struct bulk inside pending batches.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260418-r63-smallvec48/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r63-smallvec48/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r64-smallvec64/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r64-smallvec64/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r65-smallvec32/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r65-smallvec32/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260418-r66-smallvec16/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r66-smallvec16/logs/index.stderr.log`\n\n## Rejected Byte-Pass Fusion Follow-Up\n\n### Goal\n- Test a pass-fusion idea from the grouped lexical rebuild hot path: carry per-conversation `message_bytes` forward from the SQLite grouping scan so `finish_conversation` no longer walks every grouped message again just to total `content.len()`.\n\n### Alien/Graveyard Framing\n- This was a straight pass-fusion experiment: eliminate a redundant per-conversation walk and keep the observable rebuild behavior identical.\n- The measured hotspot evidence for trying it was the still-large `finish_conversation_ms` bucket inside the corrected runner harness.\n\n### Measured Round\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Rebuild ms | Message Stream ms | Finish Conversation ms | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r67-bytepass-fused` | compute grouped `message_bytes` during SQLite scan and pass them into `finish_conversation` | 59.445 | 861.053 | 79129.163 | 359.315 | 55.490 | 53.390 | 14.889 | 7.970 | 6.813 | 7.229 | rejected |\n\n### Takeaways\n- The idea was clean but it was not a win. `r67` lost by about `1.0s` against the retained `r65-smallvec32` baseline (`58.417s`).\n- The internal counters did not justify keeping it either: `message_stream_ms` rose back to `53390.355`, far above the retained `52311.599` on `r65`.\n- That means the extra byte-summing pass in `finish_conversation` is not the binding constraint here.

The hypothesis was that the default outer `add_prebuilt_documents` batch cap was underfeeding the lexical writer on the 26-thread path.\n- Because batching changes are notoriously noisy, this sweep used a sequential-validation rule: do not keep a candidate unless the improvement survives a repeat or a code-default reproduction.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Rebuild ms | Message Stream ms | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r68-control-repeat` | current retained tree, no add-batch override | 57.413 | 891.515 | 81928.571 | 372.026 | 53.953 | 51.905 | 7.745 | 6.619 | 6.946 | fresh control |\n| `r69-addbatch16384` | `CASS_TANTIVY_ADD_BATCH_MAX_MESSAGES=16384` | 57.422 | 891.378 | 81915.930 | 371.969 | 53.991 | 52.158 | 7.372 | 6.255 | 6.392 | effectively tied |\n| `r70-addbatch24576` | `CASS_TANTIVY_ADD_BATCH_MAX_MESSAGES=24576` | 56.412 | 907.342 | 83382.974 | 378.630 | 53.344 | 51.305 | 6.474 | 5.336 | 6.843 | promising outlier |\n| `r71-addbatch32768` | `CASS_TANTIVY_ADD_BATCH_MAX_MESSAGES=32768` | 78.505 | 651.998 | 59917.336 | 272.076 | 53.027 | 50.791 | 5.967 | 4.842 | 7.496 | hard regression / cliff |\n| `r73-code-default-addbatch24576` | compiled code default changed to `24576` on high-thread path, no env override | 57.425 | 891.330 | 81911.507 | 371.949 | not separately inspected | not separately inspected | not separately inspected | not separately inspected | not separately inspected | failed reproduction |\n| `r74-addbatch24576-repeat` | repeat of the `24576` env override after the code-default non-repro | 57.418 | 891.451 | 81922.692 | 372.000 | not separately inspected | not separately inspected | not separately inspected | not separately inspected | not separately inspected | failed reproduction |\n\n### Takeaways\n- The new clean-machine control (`r68`) was already materially faster than the older `58.417s` plateau, so this whole sweep had to be judged against `57.413s`, not against stale noisier runs.\n- `16384` was just noise. It improved some internal `prepare`/`add` counters but did not move wall clock.\n- `24576` produced one excellent run (`56.412s`) with much better internal `prepare_ms` and `add_ms`, but it failed both validation checks: the compiled code-default run (`r73`) and a straight env repeat (`r74`) fell back to `~57.42s`.\n- `32768` exposed a real cliff: the internal rebuild profile still looked superficially fine, but end-to-end wall time exploded to `78.505s`, which strongly suggests large outer batches can trigger delayed downstream costs outside the profiled rebuild buckets.\n- Conclusion: do not keep any add-batch default change from this sweep. The `24576` result was a false positive under sequential validation, not a stable optimization.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r68-control-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r68-control-repeat/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r69-addbatch16384/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r69-addbatch16384/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r70-addbatch24576/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r70-addbatch24576/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r71-addbatch32768/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r71-addbatch32768/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r73-code-default-addbatch24576/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r73-code-default-addbatch24576/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r74-addbatch24576-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r74-addbatch24576-repeat/logs/index.stderr.log`\n\n\n\n## Rejected Prepare-Chunking Sweep\n\n### Goal\n- Test a morsel-style prepare-stage rewrite in the lexical rebuild hot path: replace one `Vec<CassDocument>` allocation per conversation with chunked worker-local accumulation and a single final extend pass.\n\n### Alien/Queueing Framing\n- This was a queue-shape and allocation-churn experiment inspired by morsel-driven parallelism, not a semantic change. Ordering was intentionally preserved by keeping contiguous conversation chunks, preserving in-chunk order, and flattening chunk outputs in chunk order.\n- The EV case for trying it was the still-material `prepare_ms` bucket on the fresh corrected control (`r68`), which suggested that per-conversation allocation and flatten overhead might still be worth attacking locally.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Rebuild ms | Message Stream ms | Finish Conversation ms | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r75-chunked-prepare` | chunked worker-local doc accumulation in `prepare_lexical_rebuild_batch` | 57.416 | 891.473 | 81924.629 | 372.008 | 53.954 | 51.845 | 14.185 | 7.649 | 6.665 | 6.928 | tie / rejected |\n| `r76-chunked-prepare-repeat` | repeat of the same chunked worker-local prepare path | 57.420 | 891.407 | 81918.571 | 371.981 | 53.926 | 51.913 | 14.376 | 7.754 | 6.748 | 6.976 | failed repeat |\n\n### Takeaways\n- This lever did not earn its complexity. Both measured rounds were fractionally slower than the fresh retained control (`r68-control-repeat` at `57.413s`).\n- `r75` briefly looked directionally interesting because `prepare_ms` fell from the control's `7.745s` to `7.649s`, but the savings were too small and were mostly given back in `add_ms`; end-to-end wall time did not move.\n- The repeat removed any doubt. `r76` drifted the wrong way in every interesting internal bucket: `message_stream_ms`, `finish_conversation_ms`, `prepare_ms`, `add_ms`, and `commit_ms` all worsened versus `r75`.\n- Conclusion: revert the chunked prepare rewrite. The simpler per-conversation prepare path remains the correct retained implementation until there is evidence for a materially larger prepare-stage lever.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r75-chunked-prepare/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r75-chunked-prepare/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r76-chunked-prepare-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r76-chunked-prepare-repeat/logs/index.stderr.log`\n\n\n## Accepted Slice-Based Prebuilt-Doc Add Fast Path\n\n### Goal\n- Remove the extra wrapper-side buffering pass in the lexical rebuild add path. The rebuild already prepares a full `Vec<CassDocument>` per flush, but `TantivyIndex::add_prebuilt_documents` was moving every document into a second staging `Vec` before borrowing it back into `frankensearch`'s slice API.\n\n### Alien/Queueing Framing\n- This is a zero-copy ownership-transfer style optimization at the wrapper boundary, not a batching-policy change. The batch geometry stays the same; the change is that the rebuild path now submits contiguous slices of the already-prepared document vector instead of rebuilding a second buffer just to recover those same contiguous slices.\n- The relevant graveyard pattern is ownership-preserving zero-copy handoff: keep the hot path on existing contiguous buffers and avoid gratuitous queue copies when the downstream consumer already accepts borrowed slices.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes. Batches are contiguous windows over the original prepared-doc vector, and those windows are submitted in original order.\n- Tie-breaking unchanged: yes. No sort keys or batch thresholds changed.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: compile gates green plus targeted lexical-add and streamed-rebuild tests green.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | DB MiB/s | Rebuild ms | Message Stream ms | Finish Conversation ms | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r77-slice-add-fastpath` | rebuild path calls new slice-based prebuilt-doc fast path; no second staging vec | 55.395 | 924.002 | 84914.020 | 385.583 | 52.342 | 50.421 | 13.213 | 5.813 | 4.714 | 6.492 | accepted candidate |\n| `r78-slice-add-fastpath-repeat` | repeat of the same retained slice-based fast path | 56.409 | 907.398 | 83388.187 | 378.654 | 52.607 | 50.535 | 13.249 | 5.675 | 4.551 | 6.792 | accepted repeat |\n\n### Takeaways\n- This is a real retained win. Both rounds beat the fresh retained control (`r68-control-repeat` at `57.413s`).\n- The repeat held with a clear margin: `57.413s -> 56.409s`, about `1.7%` faster, while the first round reached `55.395s`.\n- The internal profile moved in the right service centers. Against `r68`, the repeat cut `prepare_ms` from `7.745s` to `5.675s` and `add_ms` from `6.619s` to `4.551s`, with `message_stream_ms` also dropping by about `1.37s`.\n- That matches the hypothesis: the wrapper-side rebuffering pass was expensive enough to matter on the real corpus, and deleting it improved both the handoff into frankensearch and the apparent upstream critical path.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r77-slice-add-fastpath/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r77-slice-add-fastpath/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r78-slice-add-fastpath-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r78-slice-add-fastpath-repeat/logs/index.stderr.log`\n\n\n## Accepted Prebuilt Add-Batch Default Retune\n\n### Goal\n- Re-evaluate the lexical rebuild add-batch default after the accepted slice-based prebuilt-doc fast path changed the hot-path balance. The earlier add-batch sweep was taken on an older tree, so its conclusions were no longer trustworthy for the retained slice fast path.\n\n### Alien/Queueing Framing\n- This is a queue geometry retune, but only at the prebuilt-doc boundary where the retained slice fast path now hands already-prepared contiguous documents directly into Tantivy/frankensearch.\n- The relevant queueing rule is local retuning after a service-center change: once the wrapper-side copy stage was removed, the old batch-size optimum became stale and needed to be re-measured on the new pipeline rather than inherited by folklore.\n- Scope stays intentionally narrow. Regular per-message indexing keeps the older default; only the prebuilt lexical rebuild slice path gets the raised floor.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes. Only batch window size changed; document order within and across batches is unchanged.\n- Tie-breaking unchanged: yes. Search fields, batch submission order, and commit cadence all stay the same.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: compile gates green plus targeted lexical-add and streamed-rebuild tests green.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | Rebuild ms | Message Stream ms | Finish Conversation ms | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r79-control-after-slice` | fresh retained control on the slice fast-path tree; code default unchanged | 56.402 | 907.501 | 83397.578 | 52.663 | 50.546 | 13.286 | 5.667 | 4.540 | 6.758 | control |\n| `r80-addbatch16384-after-slice` | env-only retune with `CASS_TANTIVY_ADD_BATCH_MAX_MESSAGES=16384` on the retained slice tree | 55.404 | 923.855 | 84900.539 | 52.122 | 50.258 | 12.945 | 5.300 | 4.155 | 6.608 | promising |\n| `r81-addbatch16384-repeat-after-slice` | repeat of the same env-only `16384` retune | 55.404 | 923.858 | 84900.830 | 51.903 | 50.078 | 12.591 | 5.331 | 4.200 | 6.158 | accepted env repeat |\n| `r82-code-default-prebuilt16384` | code default raised to `16384` for the prebuilt-doc slice path only | 56.409 | 907.395 | 83387.895 | 52.736 | 50.745 | 13.169 | 5.402 | 4.191 | 6.888 | noisy miss / inconclusive |\n| `r83-code-default-prebuilt16384-repeat` | no-env repeat of the retained code-default prebuilt-only `16384` change | 55.384 | 924.187 | 84931.058 | 51.884 | 50.180 | 12.799 | 5.387 | 4.242 | 6.269 | accepted |\n\n### Takeaways\n- The old add-batch conclusions were stale once the slice fast path removed the wrapper-side rebuffering pass. Re-measuring on the retained tree found a different stable point.\n- `16384` is the new retained default floor for the prebuilt lexical rebuild slice path. The accepted code-default repeat (`r83`) improved the fresh retained control from `56.402s` to `55.384s`, about `1.8%` faster.\n- The internal profile moved in the right places. Against `r79`, the accepted `r83` cut `prepare_ms` from `5.667s` to `5.387s`, `add_ms` from `4.540s` to `4.242s`, `commit_ms` from `6.758s` to `6.269s`, and `finish_conversation_ms` from `13.286s` to `12.799s`.\n- `r82` is deliberately kept in the history even though it lost, because a single no-env miss after two strong env repeats was not enough evidence to throw away the lever. The second no-env repeat settled the question.\n- Scope discipline mattered. The retained code raises the default only for prebuilt rebuild batches; the regular per-message indexing path stays untouched because it was not the measured winner.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r79-control-after-slice/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r79-control-after-slice/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r80-addbatch16384-after-slice/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r80-addbatch16384-after-slice/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r81-addbatch16384-repeat-after-slice/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r81-addbatch16384-repeat-after-slice/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r82-code-default-prebuilt16384/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r82-code-default-prebuilt16384/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r83-code-default-prebuilt16384-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r83-code-default-prebuilt16384-repeat/logs/index.stderr.log`\n\n\n## Rejected Frankensearch Internal Add-Plan Batch Sweep\n\n### Goal\n- Re-test the inner `frankensearch` parallel-add chunk geometry after the retained slice fast path and prebuilt `16384` outer-batch retune changed the upstream handoff shape.\n\n### Alien/Queueing Framing\n- This is a second-stage queueing probe: the retained outer batch now hands the writer a different workload, so the internal `cass_parallel_add_target_batch_docs` constant inside `frankensearch` might have become stale even if the outer retune held.\n- The relevant graveyard rule is coupled service-center retuning: once an upstream boundary changes, a downstream chunking heuristic must be revalidated rather than assumed.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes. Only internal chunk geometry changed via env overrides.\n- Tie-breaking unchanged: yes. No schema, sort, or query behavior changed.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: env-only benchmark sweep; retained source tree unchanged.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | Rebuild ms | Message Stream ms | Finish Conversation ms | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r84-paraddocs1024` | env-only `CASS_TANTIVY_PARALLEL_ADD_BATCH_DOCS=1024` | 58.291 | 878.092 | 80695.006 | 55.035 | 53.135 | 14.644 | 7.427 | 6.303 | 6.211 | rejected |\n| `r85-paraddocs256` | env-only `CASS_TANTIVY_PARALLEL_ADD_BATCH_DOCS=256` | 57.080 | 896.723 | 82407.160 | 53.697 | 51.770 | 12.930 | 4.737 | 3.583 | 7.101 | rejected |\n\n### Takeaways\n- The whole inner-add batch-doc sweep is a non-winner on the retained tree. `1024` was a hard regression, and `256` also lost despite looking directionally nicer in `prepare_ms` and `add_ms`.\n- The `256` round is especially informative: it cut `prepare_ms` and `add_ms` substantially, but the savings came back as a much worse `commit_ms` bill. That is exactly the kind of coupled-queue trap that makes isolated thermostat tuning unreliable.\n- Conclusion: keep the default `512` internal add-plan target inside `frankensearch`. The retained tree is better served by a structural lever than by further inner-batch folklore.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r84-paraddocs1024/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r84-paraddocs1024/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r85-paraddocs256/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r85-paraddocs256/logs/index.stderr.log`\n\n\n## Accepted Borrowed Prebuilt-Doc Refs via Local Frankensearch Override\n\n### Goal\n- Remove the intermediate owned `CassDocument` layer from the lexical rebuild path. The grouped rebuild batch already owns the conversation rows and message strings, so cloning them into `CassDocument` and then cloning again into Tantivy documents was redundant.\n\n### Alien/Queueing Framing\n- This is an ownership-transport optimization using the exact pinned `frankensearch` rev already declared by cass (`8e07d082`). The local patch override only changes source resolution so the sibling checkout can expose a borrowed-doc API; it does not switch cass to a different upstream revision.\n- The relevant graveyard pattern is ownership-preserving zero-copy handoff plus local-to-global queue repair. The winning shape was not merely “borrowed refs”; it was “borrowed refs while preserving the old parallel shard prep geometry.”\n- That distinction mattered. The first serial borrowed-ref prototype (`r86`) regressed badly because it deleted clone work and parallel fanout at the same time. Restoring parallel shard construction on borrowed refs produced the actual win.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes. Each borrowed ref is emitted in the same `(conversation_id, idx)` order as the old owned-doc path, and the slice batching logic is unchanged.\n- Tie-breaking unchanged: yes. Same schema fields, same commit cadence, same batch boundaries, same search semantics.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: compile gates green plus targeted lexical-add and streamed-rebuild tests green.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | Rebuild ms | Message Stream ms | Finish Conversation ms | Prepare ms | Add ms | Commit ms | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r86-borrowed-docrefs` | first borrowed-ref prototype with serial ref construction | 59.469 | 860.706 | 79097.240 | 56.175 | 54.111 | 13.858 | 6.145 | 5.087 | 7.232 | rejected prototype |\n| `r87-borrowed-docrefs-parallel` | borrowed refs plus restored parallel shard construction | 55.258 | 926.288 | 85124.121 | 52.357 | 50.513 | 12.007 | 4.985 | 4.324 | 6.558 | accepted candidate |\n| `r88-borrowed-docrefs-parallel-repeat` | repeat of the retained parallel borrowed-ref path | 55.200 | 927.264 | 85213.782 | 52.372 | 50.456 | 12.301 | 4.840 | 4.189 | 7.194 | accepted repeat |\n\n### Takeaways\n- This is a real but modest retained win. The repeat held against the previous retained baseline (`r83-code-default-prebuilt16384-repeat` at `55.384s`): `55.384s -> 55.200s`, about `0.3%` faster.\n- The improvement is small enough that the failed `r86` prototype matters. Without the parallel shard construction, the borrowed-ref idea was decisively wrong. With parallel shard construction restored, the clone-elimination becomes net positive.\n- The repeat profile supports the story. Against `r83`, `r88` cut `prepare_ms` from `5.387s` to `4.840s` and `finish_conversation_ms` from `12.799s` to `12.301s`, while `add_ms` stayed effectively tied (`4.242s -> 4.189s`). `commit_ms` drifted up, which is why the total win stayed small.\n- Conclusion: keep the borrowed prebuilt-doc ref path and the local `frankensearch` override, but describe it honestly as a narrow structural win rather than a breakthrough.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r86-borrowed-docrefs/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r86-borrowed-docrefs/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r87-borrowed-docrefs-parallel/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r87-borrowed-docrefs-parallel/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r88-borrowed-docrefs-parallel-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r88-borrowed-docrefs-parallel-repeat/logs/index.stderr.log`\n\n\n## Rejected Edge-Ngram and Preview Micro-Optimizations\n\n### Goal\n- Probe two remaining per-document string hot paths inside `frankensearch` lexical ingest after the retained borrowed-ref handoff win: edge-ngram generation and preview construction.\n\n### Alien/Queueing Framing\n- Both ideas targeted the same measured symptom: residual per-message transform cost after ownership transport had already been tightened.\n- The graveyard lesson here is that local micro-allocation reductions can still lose globally once branch behavior, UTF-8 scanning shape, and downstream writer overlap are accounted for. “Fewer obvious allocations” is not itself a proof of lower end-to-end service time.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes. Both experiments only rewrote pure string-preparation helpers.\n- Tie-breaking unchanged: yes. No query, schema, commit, or batch-boundary changes.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: helper behavior pinned with direct unit tests; real-corpus benchmark rejected both runtime changes.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | Outcome |\n|---|---|---:|---:|---:|---|\n| `r89-edgegrams-streaming` | remove per-word edge-ngram index `Vec` and stream prefixes directly | 56.400 | 907.535 | 83400.780 | rejected |\n| `r90-preview-slice` | build previews from one bounded UTF-8 slice instead of char-by-char pushes | 57.250 | 894.061 | 82162.515 | rejected |\n\n### Takeaways\n- Both ideas lost cleanly against the retained baseline `r88-borrowed-docrefs-parallel-repeat = 55.200s`.\n- `r89` shows the classic micro-optimization trap: deleting a small heap allocation inside a tight loop changed the local work shape, but the real corpus still got slower end-to-end.\n- `r90` was even worse. The slice-based preview path looked cheaper on paper, but on the real workload it produced the slowest result of the pass.\n- Conclusion: keep the previous retained runtime path unchanged. The remaining high-EV frontier is still deeper lexical ingest structure, not isolated helper rewrites of already-bounded string transforms.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260418-r89-edgegrams-streaming/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r90-preview-slice/logs/summary.json`\n\n\n## Rejected SmallVec Doc-Ref Shard Buffer\n\n### Goal\n- Test whether per-conversation `CassDocumentRef` shard construction in the retained borrowed-ref rebuild path was still paying enough heap-allocation tax to justify an inline buffer.\n\n### Alien/Queueing Framing\n- This was a local buffer-shape probe on the post-`r88` path: each conversation still builds a temporary doc-ref shard before the batch is flattened and handed to Tantivy.\n- The expected value case was simple and valid: previous `SmallVec` use in the storage scan path had already produced one real win, so it was reasonable to re-test the same primitive at the next queue boundary.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes.

Row order, conversation boundaries, and batch/commit decisions were unchanged.\n- Tie-breaking unchanged: yes. Only an extra aggregate was threaded through the existing callback contract.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: compile-gated before benchmark; runtime change rejected on the real corpus and reverted.\n\n### Measured Round\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r92-streamed-message-bytes` | carry grouped `message_bytes` from SQLite scan into `finish_conversation` | 59.475 | 860.612 | 79088.625 | 53.779 | 13.497 | 5.911 | 5.198 | 7.216 | rejected |\n\n### Takeaways\n- This did not merely fail to help wall clock; it regressed the local target bucket too. `finish_conversation_ms` worsened from the retained `r88` value of `12.301s` to `13.497s`.\n- `prepare_ms` and `add_ms` also moved in the wrong direction, so the extra callback plumbing and per-row accumulation cost more than the removed second pass.\n- Conclusion: keep the simpler existing callback contract and continue hunting deeper than this local sufficient-statistics tweak.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260418-r92-streamed-message-bytes/logs/summary.json`\n- `/tmp/cass-real-bench-20260418-r92-streamed-message-bytes/logs/index.stderr.log`\n\n\n\n## Clean 048d5fa8 Baseline Reset, Rejected Repin, and Retained Edge-Ngram Helper Reversal\n\n### Goal\n- Re-establish the true control on the current clean tree, then test whether the faster older `cass_generate_edge_ngrams` helper was a real lever or just another edge-ngram false positive.\n\n### Alien/Queueing Framing\n- This pass corrected the control plane before changing the data plane. The repo had drifted back to the clean git-pinned `frankensearch` `048d5fa8` state, so the old `r88` local-override number was no longer the right baseline.\n- The graveyard lesson was the same constants-over-asymptotics warning that already showed up in the rejected `r89` streaming rewrite: fewer obvious temporaries does not guarantee a lower service-time envelope. Here, the older per-word index-vector helper won decisively once measured against the true clean control.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes. The retained change only swaps the `frankensearch` source from the pinned git checkout to the local sibling checkout containing the older `cass_generate_edge_ngrams` helper; document order, batch order, commit cadence, and lexical schema are unchanged.\n- Tie-breaking unchanged: yes. No query, scoring, or shard-order changes.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: compile-gated and re-benchmarked on the real corpus; the bad `3c486a1d` repin was rejected and reverted.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `prepare_ms` | `add_ms` | `commit_ms` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---|\n| `r93-clean-048d5fa8` | fresh control on current clean git-pinned `frankensearch` `048d5fa8` | 60.447 | 846.706 | 77815.221 | 54.886 | 5.288 | 4.608 | 7.270 | control |\n| `r94-repin-3c486a1d` | repin `frankensearch` git rev to `3c486a1d` | 61.466 | 832.662 | 76524.167 | 55.693 | 5.605 | 4.924 | 9.791 | rejected |\n| `r95-048d5fa8-old-edgegrams` | scratch dependency checkout: restore older `cass_generate_edge_ngrams` helper | 58.431 | 876.018 | 80503.520 | 52.655 | 5.249 | 4.582 | 7.572 | candidate |\n| `r96-048d5fa8-old-edgegrams-repeat` | repeat same scratch helper reversal | 57.420 | 891.407 | 81918.620 | 51.514 | 5.053 | 4.407 | 7.162 | candidate-repeat |\n| `r97-local-frankensearch-patch` | retained tree: enable local `frankensearch` `[patch]` override using sibling checkout with older helper | 56.410 | 907.375 | 83386.041 | 51.082 | 5.010 | 4.347 | 7.219 | kept |\n\n### Takeaways\n- The clean current baseline is `r93 = 60.447s`. That is the correct control for this pass, not the earlier local-override `r88` number.\n- The simple git repin to `3c486a1d` was wrong. `r94 = 61.466s` lost cleanly and was reverted.\n- Restoring the older helper inside `frankensearch-lexical::cass_generate_edge_ngrams` is a real win in the current environment. The retained-tree confirmation `r97 = 56.410s` improves on the clean control by about `6.7%` (`60.447s -> 56.410s`).\n- The internal buckets support the wall-clock result. Against `r93`, `r97` cut `message_stream_ms` from `54.886s` to `51.082s`, `prepare_ms` from `5.288s` to `5.010s`, and `add_ms` from `4.608s` to `4.347s`.\n- Conclusion: keep the local `frankensearch` override in `Cargo.toml` and the older edge-ngram helper in the sibling `frankensearch` checkout. The remaining frontier is still deeper lexical ingest structure, but this pass produced another retained real-corpus win.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r93-clean-048d5fa8/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r93-clean-048d5fa8/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r94-repin-3c486a1d/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r94-repin-3c486a1d/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r95-048d5fa8-old-edgegrams/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r95-048d5fa8-old-edgegrams/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r96-048d5fa8-old-edgegrams-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r96-048d5fa8-old-edgegrams-repeat/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r97-local-frankensearch-patch/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r97-local-frankensearch-patch/logs/index.stderr.log`\n\n\n## Retained Stack-Buffered Edge-Ngram Helper\n\n### Goal\n- Keep the faster old edge-ngram semantics from `r97`, but remove the remaining per-word heap `Vec<usize>` allocation inside `cass_generate_edge_ngrams`.\n\n### Alien/Queueing Framing\n- This is a bounded automaton/state-buffer rewrite rather than a new algorithm. The helper only ever needs the first 21 boundary indices, so a fixed stack buffer is enough to preserve the exact prefix envelope while avoiding heap traffic on every token.\n- The earlier streaming rewrite failed because it changed the work shape too much. This version keeps the winning old semantics and only changes the storage substrate for the bounded index set.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes. Prefixes are emitted in the same per-word order as before.\n- Tie-breaking unchanged: yes. No schema, query, commit, or batch-boundary changes.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: helper unit tests for expected prefixes and 20-char cap passed in local `frankensearch`; retained-tree cass rebuild tests also passed.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r97-local-frankensearch-patch` | retained control with old helper + local sibling override | 56.410 | 907.375 | 83386.041 | 51.082 | 12.597 | 5.010 | 4.347 | 7.219 | control |\n| `r98-stack-edgegrams` | replace per-word `Vec<usize>` with fixed `[usize; 21]` buffer | 55.385 | 924.172 | 84929.680 | 49.419 | 11.002 | 3.021 | 2.390 | 7.590 | candidate |\n| `r99-stack-edgegrams-repeat` | repeat same stack-buffer helper | 55.401 | 923.901 | 84904.713 | 49.438 | 11.013 | 3.120 | 2.460 | 7.595 | kept |\n\n### Takeaways\n- The repeat held almost exactly: `55.385s` and `55.401s`.\n- Against the retained `r97` control, the kept helper improves wall clock by about `1.8%` (`56.410s -> 55.401s`).\n- The hot buckets moved sharply in the expected direction. Against `r97`, `r99` reduced `prepare_ms` from `5.010s` to `3.120s`, `add_ms` from `4.347s` to `2.460s`, and `finish_conversation_ms` from `12.597s` to `11.013s`.\n- Conclusion: keep the stack-buffered helper in the sibling `frankensearch` checkout along with the existing local override. The remaining frontier is now even less about prefix-helper folklore and more about deeper lexical document-build structure.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r98-stack-edgegrams/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r98-stack-edgegrams/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r99-stack-edgegrams-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r99-stack-edgegrams-repeat/logs/index.stderr.log`\n\n\n## Retained Fused Content Prefix + Preview Scan\n\n### Goal\n- Remove the second scan over message content during lexical document build by fusing `content_prefix` generation and preview extraction into one pass, while preserving the exact outputs of `cass_generate_edge_ngrams(content)` and `cass_build_preview(content, 400)`.\n\n### Alien/Queueing Framing\n- This is a deterministic finite-state scanner on the hottest per-document path. The content string was being traversed once for edge-ngram generation and again for preview extraction; the fused helper keeps the same output contract but collapses those traversals into a single bounded state machine.\n- The risk gate was constants-sensitive rather than algorithmic. Prior preview-only rewrites had lost, so this version kept the old winning prefix semantics and differential-tested the fused helper directly against the existing standalone helpers before benchmarking.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes. Token boundary handling, per-word prefix ordering, and preview truncation semantics are unchanged.\n- Tie-breaking unchanged: yes. No query, schema, commit, or batch-boundary changes.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: local `frankensearch-lexical` test confirms the fused helper matches `cass_generate_edge_ngrams` plus `cass_build_preview(..., 400)` on representative ASCII, Unicode, punctuation, CJK, and long-input samples; retained-tree cass rebuild tests also passed.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r99-stack-edgegrams-repeat` | retained control with stack-buffered edge-ngram helper | 55.401 | 923.901 | 84904.713 | 49.438 | 11.013 | 3.120 | 2.460 | 7.595 | control |\n| `r100-fused-content-scan` | one-pass fused `content_prefix + preview` builder | 54.411 | 940.717 | 86450.119 | 48.770 | 10.503 | 3.224 | 2.565 | 6.803 | candidate |\n| `r101-fused-content-scan-repeat` | repeat same fused content scan | 54.377 | 941.292 | 86502.946 | 48.432 | 10.628 | 2.972 | 2.347 | 7.399 | kept |\n\n### Takeaways\n- The repeat held: `54.411s` and `54.377s`.\n- Against the retained `r99` control, the kept fused helper improves wall clock by about `1.8%` (`55.401s -> 54.377s`).\n- Against the clean `r93` baseline (`60.447s`), the current retained tree is now about `10.0%` faster.\n- The hot buckets moved in the right direction again. Against `r99`, `r101` reduced `message_stream_ms` from `49.438s` to `48.432s`, `finish_conversation_ms` from `11.013s` to `10.628s`, `prepare_ms` from `3.120s` to `2.972s`, and `add_ms` from `2.460s` to `2.347s`.\n- Conclusion: keep the fused content builder in the sibling `frankensearch` checkout together with the existing local override. The next frontier is no longer obvious string rescans; it is deeper document materialization and writer interaction structure.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r100-fused-content-scan/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r100-fused-content-scan/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r101-fused-content-scan-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r101-fused-content-scan-repeat/logs/index.stderr.log`\n\n\n## Corrected Actual Cass Tokenizer Retest\n\n### Goal\n- Re-run the custom `CassTokenizer` change on a freshly relinked runner after discovering that the earlier `r102`/`r103` numbers were produced by a stale binary that still contained `RegexTokenStream`.\n\n### Alien/Queueing Framing\n- The original hotspot diagnosis was still valid: the retained `r101` tree spent a dominant share of ingest CPU inside Tantivy regex tokenization (`regex_automata::dfa::search::find_fwd` at `38.17%` children / `34.73%` self, `RegexTokenStream::advance` at `29.29%` children in `/tmp/cass-r101-control.perf.data`).\n- The correction was procedural rather than conceptual. After forcing a fresh cass relink and confirming `/tmp/cass_runner_r59` actually contained `CassTokenizer`, the same finite-state rewrite could be measured honestly.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes. Token order, offsets, and positions are still differential-tested against the legacy regex tokenizer.\n- Tie-breaking unchanged: yes. No schema, query, commit cadence, or batch geometry changes.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: `cass_tokenizer_matches_legacy_regex_boundaries` passed on the sibling `frankensearch` checkout, and the retained-tree cass rebuild tests still passed.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r101-fused-content-scan-repeat` | retained control with fused content-prefix + preview scan | 54.377 | 941.292 | 86502.946 | 48.432 | 10.628 | 2.972 | 2.347 | 7.399 | control |\n| `r104-actual-cass-tokenizer` | fresh relink, actual `CassTokenizer` binary confirmed | 53.226 | 961.655 | 88374.253 | 48.050 | 9.793 | 2.964 | 2.322 | 6.314 | candidate |\n| `r105-actual-cass-tokenizer-repeat` | repeat same actual tokenizer build | 54.262 | 943.287 | 86686.240 | 48.840 | 9.837 | 3.047 | 2.383 | 6.181 | candidate-repeat |\n| `r106-actual-cass-tokenizer-tiebreak` | third run on same actual tokenizer build | 54.169 | 944.918 | 86836.170 | 48.664 | 9.960 | 3.147 | 2.473 | 6.478 | kept-control |\n\n### Takeaways\n- `r102` and `r103` were invalid and should not be used. They came from a stale runner that still contained Tantivy's regex tokenizer.\n- On the correctly relinked binary, the tokenizer rewrite still stays on the positive side, but it is a small edge rather than the earlier claimed clean repeat-held win. Against `r101`, the corrected candidate mean is `53.886s` (`0.492s`, about `0.90%` faster) and the median is `54.169s` (`0.209s`, about `0.38%` faster).\n- A fresh `perf` sample on the actual tokenizer tree (`/tmp/cass-r106-actual.perf.data`) confirmed that regex DFA cost was removed and the dominant ingest CPU shifted to the custom token stream plus Tantivy postings work. That made the next frontier clear.\n- Conclusion: keep the custom tokenizer in the local working tree as the live control for the next round, but downgrade the historical claim. The real value here is modest; the large retained win came from the follow-on postings change below.\n\n### Artifacts\n- `/tmp/cass-r101-control.perf.data`\n- `/tmp/cass-r106-actual.perf.data`\n- `/tmp/cass-real-bench-20260419-r104-actual-cass-tokenizer/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r104-actual-cass-tokenizer/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r105-actual-cass-tokenizer-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r105-actual-cass-tokenizer-repeat/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r106-actual-cass-tokenizer-tiebreak/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r106-actual-cass-tokenizer-tiebreak/logs/index.stderr.log`\n\n## Retained Prefix-Field Freq-Only Postings\n\n### Goal\n- Reduce Tantivy postings write cost by storing term frequencies but not positions for `title_prefix` and `content_prefix`, because those fields are only used by `TermQuery` paths and never by `PhraseQuery`.\n\n### Alien/Queueing Framing\n- The actual `r106` profile moved the bottleneck from regex DFA into Tantivy postings (`SpecializedPostingsWriter<TfAndPositionRecorder>::subscribe` and related serialization paths) while token-prep time stayed comparatively smaller.\n- This made the highest-EV move a structural schema reduction rather than another tokenizer trick: keep BM25 term-frequency scoring on prefix fields, but stop paying to record positions that no query path ever reads.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes. Document order, token order, batch order, and commit cadence are unchanged.\n- Tie-breaking unchanged: yes in the intended scoring contract. `title_prefix` and `content_prefix` still store frequencies, and phrase queries continue to target only `title` and `content`.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: new `frankensearch-lexical` test asserts that both prefix fields now store `IndexRecordOption::WithFreqs`; the tokenizer differential test and fused-helper differential test still pass; retained-tree cass rebuild tests also passed.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r106-actual-cass-tokenizer-tiebreak` | live control with actual custom tokenizer | 54.169 | 944.918 | 86836.170 | 48.664 | 9.960 | 3.147 | 2.473 | 6.478 | control |\n| `r107-prefix-freqs-candidate` | `title_prefix` / `content_prefix` store freqs without positions | 51.367 | 996.448 | 91571.686 | 45.986 | 7.434 | 3.033 | 2.370 | 3.837 | candidate |\n| `r108-prefix-freqs-repeat` | repeat same freq-only prefix postings schema | 52.362 | 977.519 | 89832.120 | 46.525 | 7.401 | 3.039 | 2.381 | 3.778 | kept |\n\n### Takeaways\n- This is a real retained win. Against the live `r106` control, the two runs improved wall clock by `2.801s` (`5.17%`) and `1.807s` (`3.34%`); the candidate mean is `51.865s`, about `4.25%` faster than control.\n- The bucket movement matches the hypothesis almost perfectly. Against `r106`, the repeat `r108` cut `message_stream_ms` from `48.664s` to `46.525s`, `finish_conversation_ms` from `9.960s` to `7.401s`, and `commit_ms` from `6.478s` to `3.778s`, while `prepare_ms` and `add_ms` stayed essentially flat.\n- Relative to the clean `r93 = 60.447s` baseline, the current retained tree is now about `13.4%` faster on the real corpus using the conservative repeated `r108` number.\n- Conclusion: keep the freq-only prefix postings schema in the sibling `frankensearch` checkout together with the existing local override. The next frontier is now even deeper inside Tantivy ingest and writer interaction rather than in token-boundary work.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r107-prefix-freqs-candidate/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r107-prefix-freqs-candidate/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r108-prefix-freqs-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r108-prefix-freqs-repeat/logs/index.stderr.log`\n\n\n## Retained Preview Stored-Only Field\n\n### Goal\n- Remove useless tokenization and postings work for `preview`, which cass stores as a fallback display field but never targets in lexical query construction.\n\n### Alien/Queueing Framing\n- The control profile after `r108` still showed Tantivy tokenization and postings dominating rebuild cost, so the highest-EV next lever was to cut write amplification from a field that did not contribute to retrieval.\n- This lines up with the graveyard guidance to eliminate needless index work before chasing more exotic local hot-loop tricks: if a field only needs stored retrieval semantics, indexing it is pure ingest tax.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes. Document build order, flush cadence, commit cadence, and query result ordering are unchanged.\n- Tie-breaking unchanged: yes. `preview` is still stored and retrievable, but lexical query construction does not target it; the fallback read path in `src/search/query.rs` still reads the stored field.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: new `frankensearch-lexical` test asserts that `preview` is stored-only; prefix-field and fused-helper tests still pass; retained-tree cass rebuild tests also passed.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r108-prefix-freqs-repeat` | live control with freq-only prefix postings | 52.362 | 977.519 | 89832.120 | 46.525 | 7.401 | 3.039 | 2.381 | 3.778 | control |\n| `r109-preview-stored-only` | `preview` changed from `TEXT | STORED` to `STORED` | 51.365 | 996.493 | 91575.771 | 46.188 | 7.464 | 3.178 | 2.542 | 3.597 | candidate |\n| `r110-preview-stored-only-repeat` | repeat same stored-only preview schema | 52.379 | 977.213 | 89804.033 | 47.100 | 7.868 | 3.301 | 2.639 | 3.752 | statistical tie |\n| `r111-preview-stored-only-tiebreak` | tiebreak repeat on same schema | 51.378 | 996.248 | 91553.265 | 46.606 | 7.665 | 3.184 | 2.543 | 3.867 | kept |\n\n### Takeaways\n- This is a modest but retained win. Against the live `r108` control, two of three runs improved wall clock by `0.997s` (`1.90%`) and `0.984s` (`1.88%`); the middle repeat was effectively flat at `-0.016s` (`-0.03%`). The three-run candidate mean is `51.707s`, about `1.25%` faster than control.\n- The strongest deterministic gain is index size. Removing `preview` postings shrank the produced index from `3,452,397,136` bytes to `3,236,213,871` bytes on `r111`, a reduction of `216,183,265` bytes (`6.26%`).\n- The rebuild stage buckets were noisier than the wall clock on this round, so the keep decision is based primarily on repeated end-to-end time plus the structural proof that `preview` indexing was unused work.\n- Relative to the clean `r93 = 60.447s` baseline, the current retained tree is now about `15.0%` faster on the real corpus using the conservative repeated `r111` number.\n- Conclusion: keep `preview` as stored-only in the sibling `frankensearch` checkout together with the existing local override. The next frontier is likely deeper Tantivy writer/postings structure again, not more unused-field cleanup.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r109-preview-stored-only/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r109-preview-stored-only/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r110-preview-stored-only-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r110-preview-stored-only-repeat/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r111-preview-stored-only-tiebreak/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r111-preview-stored-only-tiebreak/logs/index.stderr.log`\n\n\n## Rejected Prefix Direct-Term Stream\n\n### Goal\n- Eliminate the hot `hyphen_normalize` tokenizer stack on `title_prefix` and `content_prefix` by precomputing the exact legacy prefix-field term stream up front, then indexing those fields with a cheap whitespace-plus-lowercase analyzer.\n\n### Alien/Queueing Framing\n- The fresh `r111` profile still showed `RemoveLongFilterStream<...CassTokenStream>::advance` and Tantivy postings subscription dominating ingest CPU, so the highest-EV hypothesis was to remove analyzer-layer work from the already-precomputed prefix fields.\n- The design used a proof-carrying direct term stream: preserve the indexed prefix terms exactly, but move their construction out of Tantivy’s tokenizer pipeline.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes in the attempted design. Document order, flush cadence, commit cadence, and field/query structure were unchanged.\n- Tie-breaking unchanged: yes by construction in the proof harness. A differential test showed the new direct prefix stream produced the same analyzed token sequence as the legacy prefix analyzer on representative ASCII, CJK, accented, and mixed-script samples.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: the new `frankensearch-lexical` differential test passed locally before the benchmark run.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r111-preview-stored-only-tiebreak` | live retained control | 51.378 | 996.248 | 91553.265 | 46.606 | 7.665 | 3.184 | 2.543 | 3.867 | control |\n| `r112-prefix-direct-terms` | precompute exact prefix-field terms + whitespace tokenizer | 53.383 | 958.818 | 88113.512 | 47.855 | 8.161 | 3.733 | 3.038 | 3.665 | rejected |\n\n### Takeaways\n- This candidate lost clearly on the first real-corpus run: `+2.006s` slower than control (`+3.90%`). That is too large to justify a repeat.\n- The failure mode is visible in the stage buckets. Relative to `r111`, `message_stream_ms` rose from `46.606s` to `47.855s`, `finish_conversation_ms` rose from `7.665s` to `8.161s`, and both `prepare_ms` and `add_ms` got materially worse. `commit_ms` improved slightly, but nowhere near enough to offset the added precompute cost.\n- The direct term-stream proof was not the problem; the cost model was. Moving the exact token construction out of Tantivy and into cass’s prep path simply shifted too much work into the single-threaded prebuild side.\n- Conclusion: reject the direct-prefix-term / dedicated-prefix-tokenizer rewrite and restore the prior retained tree.\n\n### Artifacts\n- `/tmp/cass-r111-control.perf.data`\n- `/tmp/cass-real-bench-20260419-r112-prefix-direct-terms/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r112-prefix-direct-terms/logs/index.stderr.log`\n\n\n## Rejected CJK Bigram Fast Path\n\n### Goal\n- Remove the unconditional per-token `Vec<char>` allocation inside `CjkBigramDecompose` by scanning tokens allocation-free first and only materializing bigrams for all-CJK multi-character tokens.\n\n### Alien/Queueing Framing\n- The fresh retained-tree profile still had `RemoveLongFilterStream<...CassTokenStream>::advance` dominating rebuild CPU, and the CJK filter was one of the last remaining analyzer stages doing per-token heap work even for plain ASCII tokens.\n- This was a classic graveyard hot-loop candidate: keep semantics fixed, eliminate useless allocation on the common path, and let the writer stage stay unchanged.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes in the attempted design. Token order, document order, flush cadence, and commit cadence were unchanged.\n- Tie-breaking unchanged: yes. The attempted rewrite emitted the same bigram sequence for CJK tokens and passed through non-CJK tokens unchanged.\n- Floating-point: N/A.\n- RNG seeds: unchanged / N/A.\n- Golden/replay verification: focused lexical tests passed before benchmarking, including existing CJK bigram tests and a temporary differential proof against the legacy helper.\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r113-cjk-fastpath-control` | retained control on rebuilt real profiling binary | 56.513 | 905.714 | 83233.432 | 50.738 | 7.505 | 3.092 | 2.445 | 3.731 | control |\n| `r114-cjk-fastpath-candidate` | allocation-free CJK scan + reverse-slice bigram build | 56.508 | 905.806 | 83241.865 | 50.639 | 7.361 | 3.136 | 2.429 | 3.555 | candidate |\n| `r115-cjk-fastpath-repeat` | repeat same fast-path build | 56.506 | 905.830 | 83244.053 | 51.011 | 7.481 | 3.139 | 2.437 | 3.761 | statistical tie |\n\n### Takeaways\n- This is noise, not a keeper. The candidate mean (`56.507s`) beat control (`56.513s`) by only `0.006s`, about `0.01%`, which is far below the threshold worth retaining.\n- The first candidate run looked mildly encouraging in stage buckets, but the repeat gave that back: `message_stream_ms` rose from `50.639s` to `51.011s`, `finish_conversation_ms` rose from `7.361s` to `7.481s`, and `commit_ms` overshot control.\n- The attempted proof was sound; the economics were not. Removing this small analyzer allocation simply does not move enough real end-to-end work on the current retained tree.\n- Conclusion: reject the CJK fast-path rewrite and restore the prior retained source state.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r113-cjk-fastpath-control/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r113-cjk-fastpath-control/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r114-cjk-fastpath-candidate/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r114-cjk-fastpath-candidate/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r115-cjk-fastpath-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r115-cjk-fastpath-repeat/logs/index.stderr.log`\n\n\n## Retained Tantivy Content Externalization\n\n### Goal\n- Stop storing full `content` in the lexical Tantivy documents, keep it indexed-only, and hydrate missing content from the authoritative SQLite database at search time.\n\n### Alien/Queueing Framing\n- This was a direct write-amplification attack from the graveyard playbook: remove a large duplicated payload from the inverted-index write path, keep query semantics intact, and pay the recovery cost only on the relatively colder read path that actually needs full content.\n- The highest-EV hypothesis was that Tantivy segment build and commit would materially benefit from deleting a multi-gigabyte stored-field stream, especially after the earlier prefix/postings wins had already squeezed easier analyzer hot loops.\n\n### Behavior Preservation Proof\n- Indexed search semantics preserved: yes. `content` remains indexed, so lexical matching, prefix terms, BM25 scoring, and ranking inputs are unchanged.\n- Result payload semantics preserved: yes. cass now hydrates missing content by `(conversation_id, msg_idx)` when available, with a compatibility fallback keyed by `(source_id, source_path, msg_idx)` for ad hoc indexes built without embedded `conversation_id`.\n- Snippet behavior preserved: yes. When Tantivy no longer stores `content`, cass synthesizes a snippet document from the hydrated content and reuses the existing snippet renderer.\n- Harness correction: the new regression proof uses a dedicated `search-index/` subdir because `TantivyIndex::open_or_create(dir.path())` rebuild semantics are allowed to clear the target directory, which would invalidate a sibling temp `cass.db` in the same root.\n- Golden/replay verification before benchmarking:\n  - `cass_content_field_is_indexed_not_stored`\n  - `tantivy_search_hydrates_long_content_when_content_field_is_not_stored`\n  - `add_prebuilt_documents_streams_large_payloads_without_dropping_docs`\n  - `rebuild_tantivy_from_db_logs_streamed_batch_stats`\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r113-cjk-fastpath-control` | retained control on rebuilt real profiling binary | 56.513 | 905.714 | 83233.432 | 50.738 | 7.505 | 3.092 | 2.445 | 3.731 | control |\n| `r116-content-externalized` | `content` changed from indexed+stored to indexed-only; search hydrates from SQLite | 54.233 | 943.802 | 86733.614 | — | — | — | — | — | candidate |\n| `r117-content-externalized-repeat` | repeat on same retained tree | 55.142 | 928.232 | 85302.775 | — | — | — | — | — | repeat |\n| `r118-content-externalized-profile` | profiled confirmation run with `CASS_TANTIVY_REBUILD_PROFILE=1` | 54.025 | 947.429 | 87066.916 | 49.067 | 6.674 | 2.971 | 2.333 | 3.106 | kept |\n\n### Takeaways\n- This is a retained win. The conservative repeated result improved from `56.513s` to `55.142s`, about `2.43%` faster.

The rebuilt index dropped from `3,215,812,765` bytes on control to `2,399,327,541` bytes on the profiled kept run, a reduction of `816,485,224` bytes (`25.39%`).\n- Conclusion: keep the content-externalization change.

It trims the remaining generic analyzer overhead while preserving the exact lexical token stream.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r121-fast-normalize-filter/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r121-fast-normalize-filter/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r122-fast-normalize-filter-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r122-fast-normalize-filter-repeat/logs/index.stderr.log`\n\n\n## Rejected ASCII-Byte DFA Tokenizer Scan\n\n### Goal\n- Replace the hot ASCII path in `CassTokenStream::advance` with a byte-wise DFA so UTF-8 decoding only happens on non-ASCII bytes.\n\n### Alien/Parser Framing\n- This was a certified parser-kernel rewrite: keep the tokenizer language and offsets identical, but switch the dominant ASCII scan from per-character decoding to a deterministic byte machine.\n- The idea was directly motivated by the retained `perf` evidence that `CassTokenStream::advance` still dominated authoritative rebuild CPU after the fused normalize+limit win.\n\n### Behavior Preservation Proof\n- Token boundary semantics preserved in the candidate: yes. `cass_tokenizer_matches_legacy_regex_boundaries` still matched the legacy regex tokenizer on the existing adversarial fixture set.\n- Analyzer output semantics preserved in the candidate: yes. `cass_normalize_and_limit_matches_legacy_pipeline` still held because the downstream analyzer stages were unchanged.\n- Golden/replay verification before benchmarking:\n  - `cass_tokenizer_matches_legacy_regex_boundaries`\n  - `cass_normalize_and_limit_matches_legacy_pipeline`\n  - `cass_build_content_prefix_and_preview_matches_existing_helpers`\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r122-fast-normalize-filter-repeat` | retained control | 53.123 | 963.526 | 88546.247 | 48.719 | 6.665 | 2.895 | 2.254 | 3.126 | control |\n| `r123-ascii-dfa-tokenizer` | byte-wise ASCII DFA in `CassTokenStream::advance` | 53.192 | 962.277 | 88431.379 | 48.651 | 6.592 | 2.896 | 2.247 | 3.120 | reject |\n| `r124-ascii-dfa-tokenizer-repeat` | attempted repeat | — | — | — | — | — | — | — | — | harness failure |\n\n### Takeaways\n- This is not a keeper. The only completed corpus run, `r123`, was slightly slower than the retained `r122` control (`53.192s` vs `53.123s`, about `0.13%` worse).\n- The internal rebuild buckets moved slightly in the right direction, but not enough to overcome wall-time noise. That is exactly the kind of near-tie that should be rejected, not rationalized into a win.\n- The attempted repeat `r124` failed before launch because the profiling binary path used by the local harness disappeared (`target-optscan/profiling/cass` missing). Since the first run already failed to beat control, the missing repeat is not worth re-running via another full profiling rebuild cycle.\n- Conclusion: reject the ASCII-byte DFA tokenizer scan and restore the prior retained tree.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r123-ascii-dfa-tokenizer/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r123-ascii-dfa-tokenizer/logs/index.stderr.log`\n\n\n## Retained Prefix Presence-Only Postings\n\n### Goal\n- Reduce Tantivy write amplification on the cass prefix fields by storing only term presence for `title_prefix` and `content_prefix`, instead of term frequencies.\n\n### Alien/Postings Framing\n- The retained `perf` evidence after the tokenizer and content-externalization wins left a clear remaining hotspot family: Tantivy postings subscription work, especially the `TermFrequencyRecorder` path that prefix fields still paid for on every emitted edge n-gram.\n- The high-EV hypothesis was that cass only needs prefix-field membership to satisfy prefix matching; exact `title` and `content` fields still carry the full BM25 term-frequency and positional signal. That makes frequency-tracked prefix postings redundant cost on the hot rebuild path.\n\n### Behavior Preservation Proof\n- Exact lexical semantics preserved: yes. `title` and `content` remain indexed with `WithFreqsAndPositions`, so exact-term BM25 scoring and phrase matching are unchanged.\n- Prefix matching semantics preserved: yes. Prefix fields remain indexed and queryable; only their posting detail drops from `WithFreqs` to `Basic`, which keeps term presence while removing redundant per-doc frequency tracking.\n- Title-only lexical retrieval preserved: yes. `title` field storage and indexing are unchanged.\n- Golden/replay verification before benchmarking:\n  - `cass_prefix_fields_store_basic_without_freqs_or_positions`\n  - `prefix_wildcard_matches_start_of_term`\n  - `edge_ngram_enables_prefix_search`\n  - `title_field_is_searchable`\n  - `wildcard_fallback_short_query_triggers_prefix`\n  - `add_prebuilt_documents_streams_large_payloads_without_dropping_docs`\n  - `rebuild_tantivy_from_db_logs_streamed_batch_stats`\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | `index_size_bytes` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r122-fast-normalize-filter-repeat` | retained control | 53.123 | 963.526 | 88546.247 | 48.719 | 6.665 | 2.895 | 2.254 | 3.126 | 2399846232 | control |\n| `r125-prefix-basic-postings` | switch `title_prefix` / `content_prefix` postings from `WithFreqs` to `Basic` | 51.716 | 989.732 | 90954.487 | 47.672 | 6.126 | 2.873 | 2.260 | 2.666 | 2062700780 | candidate |\n| `r126-prefix-basic-postings-repeat` | repeat on same retained tree | 51.528 | 993.347 | 91286.726 | 47.533 | 6.146 | 2.862 | 2.261 | 2.693 | 2063387147 | kept |\n\n### Takeaways\n- This is a retained win. The conservative repeated result improved from `53.123s` to `51.528s`, about `3.00%` faster.\n- The two candidate runs averaged `51.622s`, about `2.82%` faster than the retained control.\n- The rebuilt index also got materially smaller: `2,399,846,232` bytes on `r122` down to `2,063,387,147` bytes on repeated `r126`, a reduction of `336,459,085` bytes (`14.02%`).\n- The hot rebuild buckets moved in the right direction overall:\n  - `message_stream_ms`: `48.719s -> 47.533s` (`-2.44%`)\n  - `finish_conversation_ms`: `6.665s -> 6.146s` (`-7.79%`)\n  - `prepare_ms`: `2.895s -> 2.862s` (`-1.13%`)\n  - `commit_ms`: `3.126s -> 2.693s` (`-13.86%`)\n  - `add_ms`: essentially flat/noise (`2.254s -> 2.261s`)\n- Conclusion: keep the prefix-field `Basic` postings change. cass still gets prefix matching, but no longer pays per-document frequency bookkeeping for edge n-gram fields.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r125-prefix-basic-postings/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r125-prefix-basic-postings/logs/index.stderr.log`\n- `/tmp/cass-real-bench-20260419-r126-prefix-basic-postings-repeat/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r126-prefix-basic-postings-repeat/logs/index.stderr.log`\n\n\n## Rejected Prefix-Term Dedup Under Basic Postings\n\n### Goal\n- Exploit the fact that `title_prefix` and `content_prefix` now use `IndexRecordOption::Basic` by deduplicating repeated prefix terms within a document before handing them to Tantivy.\n\n### Alien/Set-Semantics Framing\n- This was the obvious algebraic follow-on to the retained prefix-postings win: once prefix fields are presence-only, duplicate per-document prefix terms become semantically idempotent.\n- A direct sample against the authoritative cass database suggested a plausible opportunity. On 1,000 recent conversations, the generated prefix stream averaged `191.005` total prefix terms, `126.334` unique prefix terms, and `64.671` duplicates per document (`33.86%` duplicate ratio).\n- The candidate therefore introduced exact per-document deduplication in the prefix builders using an `AHashSet<&str>`, while preserving first-occurrence order so the emitted term stream remained deterministic.\n\n### Behavior Preservation Proof\n- Prefix matching semantics preserved in the candidate: yes. Prefix fields already use presence-only postings, so duplicate term suppression does not change the logical per-document term set.\n- Deterministic output ordering preserved in the candidate: yes. The first occurrence of each prefix term was still emitted in encounter order.\n- Golden/replay verification before benchmarking:\n  - `cass_generate_edge_ngrams_deduplicates_repeated_prefix_terms`\n  - `cass_build_content_prefix_and_preview_matches_existing_helpers`\n  - `prefix_wildcard_matches_start_of_term`\n  - `edge_ngram_enables_prefix_search`\n  - `wildcard_fallback_short_query_triggers_prefix`\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | `index_size_bytes` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r126-prefix-basic-postings-repeat` | retained control | 51.528 | 993.347 | 91286.726 | 47.533 | 6.146 | 2.862 | 2.261 | 2.693 | 2063387147 | control |\n| `r127-prefix-dedup-basic-postings` | exact per-document dedup of repeated prefix terms via `AHashSet<&str>` | 53.484 | 957.008 | 87947.197 | 49.199 | 7.379 | 4.186 | 3.589 | 2.534 | 2063387344 | reject |\n\n### Takeaways\n- This is not a keeper. `r127` regressed from `51.528s` to `53.484s`, about `3.80%` slower than the retained control.\n- The candidate barely changed the rebuilt index size (`+197` bytes), so the dedup bookkeeping cost was pure overhead on the hot rebuild path.\n- The algebra was correct but the implementation economics were wrong: hashing and probing every candidate prefix term cost more than simply feeding the duplicates through Tantivy's already-cheap presence-only postings path.\n- The stage buckets make that failure mode explicit: `prepare_ms` and `add_ms` both ballooned, and `finish_conversation_ms` got materially worse too, even though `commit_ms` improved slightly.\n- Conclusion: reject exact prefix-term dedup under `Basic` postings and restore the prior retained tree.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r127-prefix-dedup-basic-postings/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r127-prefix-dedup-basic-postings/logs/index.stderr.log`\n\n\n## Rejected Preview Field Elision\n\n### Goal\n- Stop materializing the stored `preview` payload into Tantivy documents during authoritative cass rebuilds, relying on the existing SQLite content-hydration path for lexical snippets instead.\n\n### Alien/Compression Framing\n- After the retained content-hydration keeper, `preview` looked like a classic stale cache artifact: snippets already hydrate full content from SQLite whenever `content` or `snippet` is requested, so the stored preview field had become a residual duplicate of the first 400 content characters.\n- A direct corpus probe on the authoritative cass database suggested a large apparent byte opportunity: `4,703,804` messages with average preview length `112.23` characters, or about `527,918,461` raw preview characters total.\n- The candidate therefore elided preview materialization from the hot lexical document-build path while keeping the schema field and query-side fallback machinery intact.\n\n### Behavior Preservation Proof\n- Lexical content hydration preserved in the candidate: yes. `tantivy_search_hydrates_long_content_when_content_field_is_not_stored` still passed, proving full content and snippets could render from SQLite without stored Tantivy content.\n- Prefix generation semantics preserved in the candidate: yes. `cass_build_content_prefix_and_preview_matches_existing_helpers` still held for the retained helper logic, and the candidate only removed preview emission from built docs.\n- Direct preview-elision proof before benchmarking:\n  - `cass_built_documents_do_not_materialize_preview_field`\n  - `tantivy_search_hydrates_long_content_when_content_field_is_not_stored`\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | `index_size_bytes` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r126-prefix-basic-postings-repeat` | retained control | 51.528 | 993.347 | 91286.726 | 47.533 | 6.146 | 2.862 | 2.261 | 2.693 | 2063387147 | control |\n| `r128-preview-elided` | omit stored `preview` payload from built Tantivy docs | 53.243 | 961.351 | 88346.359 | 49.222 | 7.405 | 4.201 | 3.598 | 2.599 | 2063298121 | reject |\n\n### Takeaways\n- This is not a keeper. `r128` regressed from `51.528s` to `53.243s`, about `3.33%` slower than the retained control.\n- The rebuilt index barely moved: `2,063,387,147` bytes down to `2,063,298,121`, a reduction of only `89,026` bytes (`0.0043%`). The huge raw preview-character count compressed away so effectively inside Tantivy's stored-field path that it did not translate into real index-size savings.\n- The stage profile shows the failure clearly: `prepare_ms` and `add_ms` both got much worse, and `finish_conversation_ms` regressed heavily too. The tiny `commit_ms` improvement was nowhere near enough to compensate.\n- Conclusion: reject preview-field elision. In this workload, the stored preview path is not the real write-amplification lever anymore.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r128-preview-elided/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r128-preview-elided/logs/index.stderr.log`\n\n\n## Rejected Conversation-Level Title-Prefix Precompute\n\n### Goal\n- Precompute `title_prefix` once per conversation and reuse it for every message document in that conversation, instead of regenerating the same edge-ngram string for each message during lexical rebuild.\n\n### Alien/Common-Subexpression Framing\n- This was a classic conversation-constant memoization probe. In cass, `title` is constant across all messages in a conversation, so `cass_generate_edge_ngrams(title)` looked like repeated deterministic work on the hot rebuild path.\n- The relevant graveyard/optimization pattern is common-subexpression elimination at the ownership boundary: lift a pure derived artifact from per-message work into per-conversation context, then transport it through the existing borrowed-doc pipeline.\n- The EV case looked strong on paper because the corpus averages about `91.9` messages per conversation, so each surviving conversation title could have been reused many times.\n\n### Behavior Preservation Proof\n- Title search semantics preserved in the candidate: yes. The title text itself was unchanged, and the precomputed prefix payload was built with the exact same `cass_generate_edge_ngrams` helper as the old per-message path.\n- Prefix-field bytes preserved in the candidate: yes. `cass_precomputed_title_prefix_matches_runtime_generation` proved that a precomputed `title_prefix` payload matched the runtime-generated payload exactly.\n- Golden/replay verification before benchmarking:\n  - `cass_precomputed_title_prefix_matches_runtime_generation`\n  - `cass_content_field_is_indexed_not_stored`\n  - `add_prebuilt_documents_streams_large_payloads_without_dropping_docs`\n  - `rebuild_tantivy_from_db_logs_streamed_batch_stats`\n  - `title_field_is_searchable`\n\n### Measured Rounds\n\n| Label | Change | Wall s | Conv/s | Msg/s | `message_stream_ms` | `finish_conversation_ms` | `prepare_ms` | `add_ms` | `commit_ms` | `index_size_bytes` | Outcome |\n|---|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---|\n| `r126-prefix-basic-postings-repeat` | retained control | 51.528 | 993.347 | 91286.726 | 47.533 | 6.146 | 2.862 | 2.261 | 2.693 | 2063387147 | control |\n| `r131-title-prefix-precompute` | precompute `title_prefix` once per conversation and reuse it across message docs | 52.610 | 972.910 | 89408.600 | 48.005 | 6.095 | 2.788 | 2.147 | 2.704 | 2062980960 | reject |\n\n### Takeaways\n- This is not a keeper. `r131` regressed from `51.528s` to `52.610s`, about `2.10%` slower than the retained control, so it was rejected without spending another full repeat run.\n- The candidate did improve some local buckets: `prepare_ms` fell from `2.862s` to `2.788s`, `add_ms` from `2.261s` to `2.147s`, and `finish_conversation_ms` edged down from `6.146s` to `6.095s`.\n- But the dominant service center moved the wrong way: `message_stream_ms` rose from `47.533s` to `48.005s`. That means the saved per-message prefix generation work was overpaid by the new per-conversation precompute and transport overhead inside the broader rebuild pipeline.\n- The rebuilt index shrank slightly (`-406,187` bytes, about `0.02%`), but not enough to matter.\n- Conclusion: reject conversation-level `title_prefix` precompute and keep the simpler retained tree.\n\n### Artifacts\n- `/tmp/cass-real-bench-20260419-r131-title-prefix-precompute/logs/summary.json`\n- `/tmp/cass-real-bench-20260419-r131-title-prefix-precompute/logs/index.stderr.log`\n\n\n## Rejected Retained-Tree Writer-Thread Retune\n\n### Goal\n- Re-test the Tantivy writer-thread count on the current retained tree after the later content externalization, fused normalization, and prefix-postings wins materially changed the per-document service demand.\n\n### Alien/Queueing Framing\n- This was a straightforward queueing-theory retune on the write service center. The old `26`-writer default was chosen on a much heavier tree, so the natural hypothesis was that the new retained tree might want a different concurrency point.\n- Two adjacent probes were worth real money: `24` as the lower-contention candidate, and `28` as the only nearby higher-throughput neighbor that had ever looked competitive on older baselines.\n\n### Behavior Preservation Proof\n- Ordering preserved: yes.

    "content": "# Modes of Reasoning: Comprehensive Analysis of `cass`\n\n> **Project:** coding-agent-search (cass) — Unified TUI/CLI to index and search local coding agent session histories\n> **Date:** 2026-04-08\n> **Methodology:** 10-mode reasoning swarm with triangulated synthesis\n> **Confidence:** 0.85 (composite)\n\n---\n\n## 1. Executive Summary\n\nTen independent analytical agents — each applying a distinct reasoning mode — converged on a clear picture of `cass`:\n\n**The project solves a genuine, well-defined problem with impressive engineering depth, but its ambition has outrun its organizational capacity.** The core search-and-index pipeline is sound, performant, and thoughtfully designed. However, three structural issues threaten long-term sustainability:\n\n1. **The dual SQLite driver** (frankensqlite + rusqlite) is a load-bearing architectural seam that propagates complexity into every subsystem. All 10 modes identified this as problematic — the strongest convergence in the entire analysis.\n\n2. **Monolithic code concentration** — five files contain 111K lines (app.rs alone is 46K). This is an artifact of the \"no file proliferation\" AGENTS.md rule overcorrecting for AI agent misbehavior, and it inhibits decomposition, review, and contribution.\n\n3. **Feature surface area exceeds solo-developer capacity** — the project ships 18 connectors, 3 search modes, 7 analytics views, 18 themes, multi-machine SSH sync, encrypted HTML export, a web publishing platform, a background ML daemon, and more. This is enterprise-grade breadth on an alpha-stage budget.\n\n**Top 5 recommended actions (in priority order):**\n1. Fix frankensqlite's FTS5 shadow table support to eliminate the rusqlite dependency\n2. Set UDS socket permissions to 0700 after bind (security fix)\n3. Remove `DatabaseCorrupt` from retryable errors (data safety fix)\n4. Split app.rs into 10-15 focused modules\n5. Resolve the asupersync version bifurcation in the lockfile\n\n---\n\n## 2. Methodology\n\n### Mode Selection Rationale\n\nThe project is a complex Rust CLI/TUI with a custom dependency ecosystem, performance-critical search, and security-sensitive features. Mode selection targeted 3 key taxonomy axes:\n\n| Axis | Pole 1 (represented) | Pole 2 (represented) |\n|------|----------------------|----------------------|\n| Descriptive vs Normative | F7, F5, B1, F2 (what IS) | L5, I4 (what OUGHT) |\n| Single-agent vs Multi-agent | A8, F4, F3 (internal analysis) | H2, I4 (adversarial/social) |\n| Ampliative vs Non-ampliative | B1, F3 (pattern discovery) | A8 (boundary verification) |\n\n### The 10 Modes\n\n| # | Mode | Code | Category | Focus |\n|---|------|------|----------|-------|\n| 1 | Systems-Thinking | F7 | Causal | Feedback loops, emergent behavior, leverage points |\n| 2 | Root-Cause | F5 | Causal | 5-whys on structural problems |\n| 3 | Adversarial-Review | H2 | Strategic | Security, attack surfaces, trust assumptions |\n| 4 | Failure-Mode (FMEA) | F4 | Causal | Cascade failures, RPN scoring |\n| 5 | Edge-Case | A8 | Formal | Boundary conditions, degenerate inputs |\n| 6 | Inductive | B1 | Ampliative | Pattern recognition, codebase evolution |\n| 7 | Counterfactual | F3 | Causal | Alternative architecture evaluation |\n| 8 | Perspective-Taking | I4 | Dialectical | Stakeholder viewpoints, UX |\n| 9 | Scope-Control | L5 | Meta | Feature bloat, complexity budget |\n| 10 | Dependency-Mapping | F2 | Causal | Supply chain, blast radius, version drift |\n\n**Category coverage:** A, B, F, H, I, L = 6 of 12 categories.\n**Opposing pairs:** H2 (adversarial) vs I4 (empathic); L5 (reduce scope) vs F7 (see the whole system).\n\n---\n\n## 3. Taxonomy Axis Analysis\n\n### Descriptive vs Normative\n\nThe descriptive modes (F7, F5, B1, F2) mapped the system as it is: a tightly coupled franken-ecosystem with dual SQLite drivers, retry machinery, and concentrated code. The normative modes (L5, I4) judged what it should be: a leaner, more decomposed system with better onboarding and contributor accessibility.\n\n**Key insight:** The descriptive modes agree the architecture *works*. The normative modes argue it *won't scale* — not in performance, but in human cognitive capacity and maintenance burden.\n\n### Single-agent vs Multi-agent\n\nThe single-agent modes (A8, F4) found concrete bugs and edge cases (NFC/NFD asymmetry, ORDER BY IS NULL usage, DatabaseCorrupt in retry list). The multi-agent modes (H2, I4) found systemic issues: the daemon UDS socket has no permissions, the README alienates new users by front-loading agent-focused content, and the supply chain has bus factor = 1.\n\n**Key insight:** The concrete bugs are fixable in hours. The systemic issues require architectural decisions.\n\n### Ampliative vs Non-ampliative\n\nInductive reasoning (B1) discovered the \"scar tissue\" pattern: AGENTS.md rules are reactive responses to specific agent failures, and the extraction-to-franken-crate pattern is driven by protecting code from agent contamination. Edge-case analysis (A8) verified specific boundary conditions, finding that most are handled but NFC normalization and negative timestamps are not.\n\n**Key insight:** B1's evolutionary narrative explains *why* the codebase looks the way it does; A8 verifies *where* it breaks at the boundaries.\n\n---\n\n## 4. Convergent Findings (KERNEL — 3+ modes agree)\n\nThese findings were independently discovered by 3 or more modes through different analytical lenses. They represent the highest-confidence conclusions.\n\n### K1: Dual SQLite Driver Is the Central Architectural Problem\n**Discovered by:** F7, F5, F3, F4, B1, L5, F2, H2, I4 (9 of 10 modes)\n**Confidence:** 0.95\n\nfrankensqlite cannot read on-disk FTS5 shadow tables, forcing retention of rusqlite as a parallel SQLite driver. This single limitation cascades into:\n- ~900 lines of FTS5 glue code in `storage/sqlite.rs`\n- Three `unsafe impl Send` wrappers (frankensqlite uses `Rc` internally, making connections `!Send`)\n- Pervasive retry/backoff machinery (15+ call sites) for dual-driver lock contention\n- A self-reinforcing loop where agents see rusqlite in the codebase and copy it, requiring ever-more-emphatic AGENTS.md rules\n- Two independent WAL readers on the same database file, amplifying lock contention\n\n**Evidence:** `Cargo.toml:107-109` (explicit comment), `storage/sqlite.rs:800` (rusqlite FTS5 functions), `storage/sqlite.rs:67-71` (unsafe Send), `AGENTS.md:49-63` (Rule 2).\n\n**Root cause (from F5):** The decision to reimplement SQLite in Rust for one advanced feature (BEGIN CONCURRENT / MVCC) created an incomplete replacement that cannot handle the full SQLite feature surface.\n\n**Counterfactual (from F3):** Using rusqlite alone would have eliminated ~900 lines of glue code and all `unsafe impl Send` wrappers, at the cost of losing BEGIN CONCURRENT support.\n\n### K2: Monolithic Code Concentration (app.rs 46K lines, 5 files = 111K lines)\n**Discovered by:** F7, F5, F3, B1, L5, I4 (6 of 10 modes)\n**Confidence:** 0.93\n\nFive files contain 111K lines: `app.rs` (46K), `lib.rs` (22K), `storage/sqlite.rs` (17K), `query.rs` (15K), `indexer/mod.rs` (11K). This concentration:\n- Makes code review impractical (any PR touching app.rs conflicts with every other PR)\n- Slows incremental compilation (Rust recompiles entire files on change)\n- Creates a hostile environment for contributors who must navigate megafiles\n- Is an artifact of the \"No File Proliferation\" rule (AGENTS.md line 173-179), which conflates preventing `_v2.rs` variants with preventing legitimate decomposition\n\n**Root cause (from F5):** The rule was a rational overcorrection to agent file spam, but it now prevents healthy architectural decomposition.\n\n### K3: `unsafe impl Send` Is a Soundness Risk\n**Discovered by:** F7, F5, H2, F4 (4 of 10 modes)\n**Confidence:** 0.88\n\nThree locations (`storage/sqlite.rs:71`, `storage/sqlite.rs:435`, `query.rs:62`) wrap `!Send` `FrankenConnection` (which uses `Rc` internally) in newtypes with `unsafe impl Send`. The safety argument (\"Rc fields are not cloned or shared externally\") is a claim about frankensqlite internals that:\n- Cannot be verified at compile time\n- Could be silently invalidated by any upstream change to frankensqlite\n- Would cause undefined behavior (use-after-free, data race) if violated\n\n**Recommendation:** Switch frankensqlite from `Rc` to `Arc` internally. The atomic reference counting overhead is negligible compared to SQLite I/O.\n\n### K4: Wildcard Dependency Versions Create Reproducibility Risk\n**Discovered by:** F5, B1, H2, F2, I4 (5 of 10 modes)\n**Confidence:** 0.90\n\nAll ~79 crates.io dependencies use `version = \"*\"`. While `Cargo.lock` provides reproducibility for existing builds, any `cargo update` or fresh build pulls latest versions. Combined with the git-pinned custom crates, this creates a split-brain pinning strategy where custom deps are strict but everything else is unconstrained.\n\n### K5: Feature Surface Area Exceeds Solo-Developer Capacity\n**Discovered by:** L5, I4, B1, F3 (4 of 10 modes)\n**Confidence:** 0.87\n\nL5 catalogued: 18 connectors, 3 search modes, 7 analytics views, 18 themes, multi-machine SSH sync wizard, encrypted HTML export, web publishing platform (27K lines), background ML daemon, macro/asciicast recording, command palette, self-update, 6 ranking modes. This is approximately 5-10x what a single alpha-stage developer can maintain.\n\n**The pages/ module (27K lines)** is a complete web publishing platform that is functionally independent from the search tool — the strongest scope-creep candidate.\n\n### K6: Supply Chain Concentration Risk (Bus Factor = 1)\n**Discovered by:** H2, F2, I4, L5 (4 of 10 modes)\n**Confidence:** 0.89\n\nAll 6 franken crate families (~46 sub-crates in the lockfile, 5.8% of packages but disproportionate in criticality) are authored by a single developer. None are published to crates.io with broad community adoption. A compromise of the single GitHub account would compromise the entire build.\n\n### K7: Franken Ecosystem Coupling Creates Multiplicative Maintenance Burden\n**Discovered by:** F7, F5, F3, L5, F2, I4 (6 of 10 modes)\n**Confidence:** 0.91\n\nThe maintainer doesn't just maintain cass — they maintain frankensqlite (pure-Rust SQLite reimplementation), frankensearch, franken_agent_detection, frankentui, asupersync (custom async runtime), and toon (custom serialization). Each has its own correctness requirements. Changes in any one can cascade through the others. The `build.rs` contract validation system is a sophisticated guardrail, but it only catches drift at compile time.\n\n### K8: AGENTS.md Rules Are \"Scar Tissue\" from Agent Misbehavior\n**Discovered by:** F5, B1, I4 (3 of 10 modes)\n**Confidence:** 0.86\n\nEach AGENTS.md rule maps to a specific class of agent failure:\n- Rule 0 (override prerogative) → agents ignoring instructions\n- Rule 1 (no file deletion) → agents deleting critical files\n- Rule 2 (no rusqlite, \"violated OVER 10 TIMES\") → agents copying legacy patterns\n- No file proliferation → agents creating `_v2.rs` variants\n- No script-based changes → agents running brittle regex transforms\n\nThe tone escalation (\"THE OWNER IS DONE TOLERATING IT\") suggests diminishing effectiveness. Agents are not deterred by emphatic language — they're deterred by code structure.\n\n---\n\n## 5. Supported Findings (2 modes agree)\n\n### S1: Daemon UDS Socket Lacks Permissions and Authentication\n**Discovered by:** H2, F4\n**Confidence:** 0.85\n\nThe socket at `/tmp/semantic-daemon-$USER.sock` has no `chmod` after bind and no authentication. Any local user can connect and: submit arbitrary `db_path` to open/write databases, send `Shutdown` to kill the daemon, or exhaust memory via 10MB payloads. **Priority: HIGH — simple fix with `set_permissions(0o700)`.**\n\n### S2: FTS5 Repair Cascade on Search Hot Path\n**Discovered by:** F7, F4\n**Confidence:** 0.82\n\n`FrankenStorage::open()` triggers a 6-step initialization cascade including FTS consistency checks that can block for seconds. Since `SearchClient::sqlite_guard()` calls this on the search hot path, a single corrupted FTS state blows through the 60ms latency budget.\n\n### S3: Vector Index / SQLite Database Can Drift\n**Discovered by:** F7, F4\n**Confidence:** 0.80\n\nNo transactional guarantee links SQLite message inserts to FSVI vector index updates. A crash between the two creates dangling entries or orphaned rows, producing incorrect semantic search results without detection.\n\n### S4: Stale Detector Can Trigger Rebuild Storms\n**Discovered by:** F7, F4\n**Confidence:** 0.78\n\nIf a rebuild errors out partway through, the `StaleDetector` is never reset, potentially re-triggering another rebuild. No `rebuild_in_progress` guard exists.\n\n### S5: ORDER BY IS NULL Used Despite Known Limitation\n**Discovered by:** F4, A8\n**Confidence:** 0.83\n\nThree production queries use `ORDER BY ... IS NULL` patterns (`lib.rs:11532`, `query.rs:4921`, `sqlite.rs:4541`) despite AGENTS.md line 266 documenting this as unsupported in frankensqlite. If the limitation manifests as incorrect ordering rather than an error, conversations with NULL timestamps will be silently misordered.\n\n### S6: Connector Extraction to FAD Was Clearly Right\n**Discovered by:** F3, B1\n**Confidence:** 0.92\n\nAll 18 connector files are now 1-5 line re-export stubs. The extraction creates a hard boundary that prevents agent contamination, enables independent testing, and makes breadth cheap. This is the project's best architectural decision.\n\n---\n\n## 6. Divergent Findings and Unique Insights by Mode\n\nThese findings were discovered by a single mode, representing the value of analytical diversity.\n\n### From Edge-Case Analysis (A8): NFC/NFD Query Asymmetry\n**Confidence:** 0.85 | **Evidence:** `query.rs:13788-13802`\n\nThe canonicalization pipeline applies NFC normalization to indexed content, but the query sanitizer does NOT normalize queries. A user typing \"café\" with a combining accent (NFD, common on macOS) will search for \"cafe \" while indexed content stores \"café\" (NFC). The test at line 13788 explicitly documents this as \"expected behavior\" — but it is a functional correctness bug for international users.\n\n### From Dependency-Mapping (F2): asupersync Version Bifurcation\n**Confidence:** 0.92 | **Evidence:** Cargo.lock contains two distinct `asupersync 0.2.9` entries\n\nThe lockfile contains TWO copies of asupersync 0.2.9 from different sources: one from crates.io (used by fsqlite sub-crates) and one from git rev `08dd31df` (used by cass and frankensearch). If these have any type-level differences, data crossing the fsqlite↔cass boundary could cause subtle runtime bugs. The git version also pulls additional dependencies (ring, rustls) not in the registry version.\n\n### From Failure-Mode (F4): DatabaseCorrupt in Retryable Errors\n**Confidence:** 0.88 | **Evidence:** `storage/sqlite.rs:2316-2321`\n\n`retryable_franken_error` includes `DatabaseCorrupt` as a retryable error. Retrying on corruption can amplify damage — the retry loop hammers corrupt pages, partial writes land in WAL, readers see inconsistent state. This should fail fast and trigger the backup/quarantine path instead. **Single highest-impact one-line fix.**\n\n### From Failure-Mode (F4): Indexer-Daemon Writer Livelock\n**Confidence:** 0.75 | **Evidence:** `indexer/mod.rs:674-699`, `daemon/worker.rs`\n\nBoth the indexer and the daemon's background embedding worker access the same SQLite database with independent retry/backoff. Under contention, both parties can keep retrying and colliding, creating a livelock where neither makes progress.\n\n### From Perspective-Taking (I4): README Front-Loads Agent Content Over Human Onboarding\n**Confidence:** 0.82 | **Evidence:** README.md lines 77-117\n\nThe README shows Agent Mail MCP endpoint JSON-RPC payloads before screenshots or \"Why This Exists.\" No \"first run\" experience is documented — a human user who installs and types `cass` sees an empty TUI with no guidance to run `cass index` first.\n\n### From Perspective-Taking (I4): Robot Mode Should Include `_corrections` Field\n**Confidence:** 0.78\n\nWhen the forgiving CLI parser corrects agent mistakes (e.g., `-robot` → `--robot`), corrections are suppressed in robot mode JSON output. Adding a `\"_corrections\"` field would teach agents canonical syntax without polluting the data stream.\n\n### From Perspective-Taking (I4): AVX Check Prevents All Functionality on Restricted VMs\n**Confidence:** 0.80 | **Evidence:** `main.rs:33-48`\n\nThe startup AVX check exits with zero functionality on pre-2011 CPUs and some VMs/containers. There is no graceful degradation (e.g., disabling only semantic/ONNX search while keeping lexical mode working).\n\n### From Edge-Case (A8): 132 Uses of `to_string_lossy` Silently Corrupt Non-UTF-8 Paths\n**Confidence:** 0.80 | **Evidence:** 132 instances across 29 source files\n\nOn Linux, filenames can contain arbitrary bytes. Session files at paths with non-UTF-8 bytes will be indexed with replacement characters (U+FFFD), making stored paths unmatchable with filesystem paths. No warning is emitted.\n\n### From Edge-Case (A8): Negative Timestamp Handling Gap\n**Confidence:** 0.82 | **Evidence:** `analytics/query.rs:58-64`\n\n`normalize_epoch_millis` only normalizes values in range `0..100_000_000_000`. A negative second-based timestamp like `-86400` (one day before epoch) is treated as `-86400ms` instead of `-86400000ms` — a factor-of-1000 error.\n\n### From Systems-Thinking (F7): Two-Tier Search Creates Non-Deterministic Daemon Configuration\n**Confidence:** 0.78 | **Evidence:** `daemon/protocol.rs:28`\n\nThe daemon socket at `/tmp/semantic-daemon-$USER.sock` is shared with the `xf` tool. First process to bind wins. If `xf` spawns the daemon with different model/dimension settings, cass may get incompatible results without any error signal.\n\n---\n\n## 7.

New Ideas and Extensions\n\n| Idea | Source Mode | Innovation Level | Description |\n|------|-----------|-----------------|-------------|\n| Connection affinity for search | F7 | Significant | Thread-local connection affinity instead of round-robin reader pool — eliminates mutex contention and enables per-thread prepared statement caches |\n| Speculative prefetch in two-tier search | F7 | Significant | Start fast embedding while user is typing (before Enter), so HNSW results are ready on submit |\n| Write-ahead buffer for indexer | F7 | Significant | Buffer conversations in mmap append-only log, drain to SQLite in background — decouples scan from write latency |\n| `_corrections` teaching field | I4 | Incremental | Structured field in robot-mode JSON showing what was auto-corrected |\n| FTS5 proxy in frankensqlite | F7 | Radical | Wrap rusqlite internally for FTS5 only, presenting a single connection API externally |\n| Daemon configuration negotiation | F7 | Incremental | Handshake on connect to verify model/dimension compatibility with xf |\n| Cross-tier consistency epoch | F7 | Incremental | Monotonic counter incremented after both SQLite + Tantivy are updated; search waits on mismatch |\n| Freshness metadata for synced data | F4 | Incremental | Tag remote sessions with `last_verified_at` so search can indicate staleness |\n\n---\n\n## 10. Assumptions Ledger\n\nAssumptions surfaced across all 10 modes that the project makes but does not explicitly validate:\n\n| Assumption | Surfaced By | Risk If Wrong |\n|-----------|------------|---------------|\n| frankensqlite's Rc fields are never cloned or shared externally | F7,F5,H2,F4 | Undefined behavior (memory corruption) |\n| FTS5 and frankensqlite WAL readers don't interfere on same file | F7,F5 | Lock contention, data corruption |\n| First-spawned daemon's model config works for all clients | F7 | Wrong semantic results silently |\n| All session file paths are valid UTF-8 | A8 | Silent path corruption via to_string_lossy |\n| Agents respect AGENTS.md rules | B1,I4 | Continued rule violations, wrong dependencies |\n| Query input is NFC-normalized before reaching the search engine | A8 | Missed matches on macOS NFD input |\n| DatabaseCorrupt errors are transient and retryable | F4 | Corruption amplification |\n| Remote session data is current after partial sync | F4 | Stale results served without indication |\n| The single developer remains available indefinitely | F2,L5,I4 | All 46 franken sub-crates frozen |\n\n---\n\n## 11. Open Questions for Project Owner\n\n1. **Is frankensqlite's FTS5 limitation a hard technical barrier or a prioritization gap?** How much effort would it take to support on-disk shadow tables?\n2. **Is the pages/ web publishing platform intended to be a core feature or a separate product?** Its 27K lines represent a significant scope commitment.\n3. **What is the intended contributor model?** The codebase structure is optimized for solo + AI agents. Is external contribution a goal?\n4. **Has the asupersync bifurcation (crates.io vs git) caused any observed runtime issues?**\n5. **Are there plans to publish franken crates to crates.io?** This would reduce bus-factor risk and enable `cargo-audit` coverage.\n6. **Has the ORDER BY IS NULL limitation actually triggered in production queries, and if so, what was the observed behavior?**\n7. **What is the actual daemon spawn failure rate in practice?** The 5.5s worst-case timeout may be theoretical.\n\n---\n\n## 12.

Contribution Scoreboard\n\nScoring formula: `0.40 × (findings/total) + 0.30 × (unique_insights/total_unique) + 0.20 × evidence_quality + 0.10 × calibration_quality`\n\n| Mode | Code | Findings | Unique Insights | Evidence Quality | Calibration | Score | Rank |\n|------|------|----------|----------------|-----------------|-------------|-------|------|\n| Failure-Mode | F4 | 10 | 3 (DatabaseCorrupt, livelock, FMEA table) | 0.90 | 0.85 | **0.89** | 1 |\n| Systems-Thinking | F7 | 10 | 2 (cache coherence, daemon non-determinism) | 0.88 | 0.82 | **0.86** | 2 |\n| Root-Cause | F5 | 9 | 1 (5-whys chains) | 0.90 | 0.82 | **0.84** | 3 |\n| Dependency-Mapping | F2 | 8 | 2 (asupersync bifurcation, blast radius) | 0.95 | 0.92 | **0.84** | 4 |\n| Edge-Case | A8 | 11 | 3 (NFC/NFD, negative timestamps, lossy paths) | 0.85 | 0.82 | **0.83** | 5 |\n| Inductive | B1 | 10 | 2 (scar tissue thesis, evolution phases) | 0.85 | 0.87 | **0.82** | 6 |\n| Scope-Control | L5 | 8 | 1 (feature audit table) | 0.82 | 0.88 | **0.79** | 7 |\n| Perspective-Taking | I4 | 14 | 3 (_corrections field, AVX degradation, README) | 0.78 | 0.78 | **0.78** | 8 |\n| Adversarial-Review | H2 | 9 | 1 (daemon socket) | 0.85 | 0.78 | **0.77** | 9 |\n| Counterfactual | F3 | 10 | 1 (alternative evaluations) | 0.80 | 0.82 | **0.76** | 10 |\n\n**Diversity metric:** 24 unique insights across 10 modes. No single mode produced more than 3 unique findings, confirming good mode selection diversity.\n\n---\n\n## 14. Mode Performance Notes\n\n**Most productive:** F4 (Failure-Mode) produced the highest-impact unique findings (DatabaseCorrupt retryable, FMEA cascade analysis) and the most structured analytical output. F7 (Systems-Thinking) provided the deepest architectural understanding.\n\n**Most unique value:** A8 (Edge-Case) and F2 (Dependency-Mapping) found concrete, actionable issues that no other mode caught — the NFC/NFD asymmetry and asupersync bifurcation respectively.\n\n**Best evolutionary insight:** B1 (Inductive) provided the most compelling narrative of *how* the codebase reached its current state, making the structural issues understandable rather than merely catalogued.\n\n**Best stakeholder coverage:** I4 (Perspective-Taking) was the only mode to analyze the human experience (onboarding, README, AVX degradation), complementing the code-focused majority.\n\n**Least incremental value:** F3 (Counterfactual) largely confirmed what other modes found through direct analysis. However, its \"clearly right decisions\" list (Rust choice, FAD extraction, local-only architecture) provides valuable positive validation.\n\n---\n\n## 15. Mode Selection Retrospective\n\n**Would change with hindsight:**\n- **Add Bayesian (B3)** to quantify uncertainty around the \"how often do retries actually fire?\" question that multiple modes raised but none could answer\n- **Replace F3 (Counterfactual) with G7 (Means-End)** since counterfactual findings mostly duplicated other modes; means-end could have mapped the concrete path from current state to desired state\n\n**Selection validated:**\n- The F-category concentration (F2, F3, F4, F5, F7 = 5 causal modes) was justified because the project's problems are fundamentally structural/causal\n- Having both H2 (adversarial) and I4 (empathic) as opposing multi-agent modes produced genuinely different findings\n- L5 (Scope-Control) was essential — no other mode would have produced the feature audit table\n\n---\n\n## 16.

`cargo check --all-targets`\n  - `cargo clippy --all-targets -- -D warnings`\n  - `cargo fmt --check`\n\n---\n\n## 1) What cass is (purpose + technical architecture)\n\nAt a high level, `cass` is a local-first search system over coding-agent logs.\n\n### 1.1 Data flow: ingest → normalize → persist → index → search\n\n1) **Connectors** (`src/connectors/*`)\n   - Each connector knows how to detect and scan a specific agent’s data format (Codex, Claude Code, Cline, Cursor, ChatGPT, Aider, etc.).\n   - Output is a common normalized structure (conversations/messages) with metadata/provenance.\n\n2) **SQLite storage** (`src/storage/sqlite.rs`)\n   - Source of truth; append-only style.\n   - Stores agents, workspaces, conversations, messages, snippets, plus an FTS mirror (and provenance tables).\n\n3) **Tantivy full-text index** (`src/search/tantivy.rs`)\n   - Speed layer for lexical search.\n   - Includes:\n     - standard text fields (`title`, `content`)\n     - edge n-gram prefix fields (`title_prefix`, `content_prefix`) for fast prefix/typeahead\n     - stored `preview` for cheap snippet-like output\n     - provenance fields (`source_id`, `origin_kind`, `origin_host`)\n\n4) **Search client** (`src/search/query.rs`)\n   - Query parsing (terms/phrases/boolean operators).\n   - Strategy selection:\n     - exact / prefix: term query, edge n-grams\n     - suffix / substring: Tantivy `RegexQuery`\n     - fallback: if sparse results, auto-try `*term*` patterns\n   - Cache layer: sharded LRU with bloom gating for fast “typed forward” reuse.\n   - Optional semantic search via a custom CVVI vector index (below).\n\n5) **Optional semantic search**\n   - **CVVI vector index** is a custom binary format with mmap-backed slabs (`src/search/vector_index.rs`).\n   - Embedding sources:\n     - ML (FastEmbed / MiniLM) when model files exist\n     - deterministic hash embedder fallback when not.\n\n### 1.2 Runtime entry points\n\n- CLI/TUI entry: `src/main.rs` loads `.env`, calls `coding_agent_search::run()`.\n- CLI parsing and command routing: `src/lib.rs`.\n- Indexing: `src/indexer/mod.rs`:\n  - detect + scan connectors (rayon parallel)\n  - ingest into SQLite + Tantivy\n  - commit Tantivy\n  - watch mode for incremental updates\n\n---\n\n## 2) Methodology requirements (the “no guessing” performance workflow)\n\n### A) Baseline first\nBefore proposing optimizations:\n- Run a representative workload.\n- Record:\n  - p50/p95/p99 latency (separately for steady-state vs cold-open when relevant)\n  - throughput\n  - peak RSS (or another peak memory metric)\n  - exact commands and environment\n\n### B) Profile before proposing\nCapture and use:\n- CPU profiles (to find time hotspots)\n- Allocation profiles (to find memory churn)\n- I/O profiles (to identify syscall and read amplification)\n\n### C) Equivalence oracle\nFor each change, define explicit oracles:\n- “Golden outputs” or deterministic invariants (including ordering)\n- Property-based or metamorphic tests where a full golden set is too large\n\nConcrete oracle templates (copy/paste for new diffs):\n- Lexical search result identity (robot JSON):\n  - invariant: `hits.map(|h| (h.source_path, h.line_number, h.agent))` is identical, in identical order, for the same index + query + filters + limit/offset.\n- “Projection oracle” for field-lazy output:\n  - invariant: `search(fields=minimal)` equals `project(search(fields=full), minimal)` (order preserved).\n- Semantic vector search (CVVI):\n  - invariant: `results.map(|r| (r.message_id, r.chunk_idx))` identical, in identical order, for the same query embedding + filters + k.\n  - (strict mode) invariant: `results.map(|r| r.score)` identical bitwise (no FP drift).\n- Canonicalization for embeddings:\n  - invariant: `sha256(canonicalize(text))` identical for all tested texts (unit + property tests).\n\n### D) Isomorphism proof sketch\nFor each proposed diff, include:\n- Why outputs cannot change, including:\n  - ordering / tie-breaking\n  - floating point behavior (if present)\n  - RNG seeds (if present)\n\nImportant policy for this repo (default):\n- If an optimization changes floating point evaluation order (SIMD reductions, parallel partial sums, fused-multiply-add), it is **not** considered isomorphic unless we explicitly gate it behind an opt-in flag and update the oracle to tolerate drift.\n\n### E) Opportunity matrix\nRank candidates by:\n```\n(Impact × Confidence) / Effort\n```\nFocus on likely p95+/throughput wins or meaningful memory reductions.\n\n### F) Minimal diffs\n- One lever per change.\n- No unrelated refactors.\n- Include rollback guidance.\n\n### G) Regression guardrails\nAdd thresholds/bench tests where feasible to prevent “perf backslide”.\n\n---\n\n## 3) Baseline workload + metrics (pre-change)\n\n### 3.1 Representative corpus (synthetic, isolated)\n\nTo avoid indexing any real home directories, we used:\n- Synthetic Codex sessions under `/tmp/cass_bench_codex/sessions` (3000 sessions × 12 msgs).\n- Fully isolated cass data dir:\n  - `--data-dir /tmp/cass_bench_data_isolated`\n  - `HOME=/tmp/cass_bench_home` plus `XDG_*` under that home\n  - `CASS_IGNORE_SOURCES_CONFIG=1` to avoid picking up remote sources config\n  - `CODING_AGENT_SEARCH_NO_UPDATE_PROMPT=1` to prevent update prompt noise\n\n### 3.2 Baseline indexing\n\nCommand:\n```bash\n/usr/bin/time -v env \\\n  HOME=/tmp/cass_bench_home \\\n  XDG_CONFIG_HOME=/tmp/cass_bench_home/.config \\\n  XDG_DATA_HOME=/tmp/cass_bench_home/.local/share \\\n  XDG_CACHE_HOME=/tmp/cass_bench_home/.cache \\\n  CODEX_HOME=/tmp/cass_bench_codex \\\n  CASS_IGNORE_SOURCES_CONFIG=1 \\\n  CODING_AGENT_SEARCH_NO_UPDATE_PROMPT=1 \\\n  ./target/release/cass --color=never \\\n  index --full --force-rebuild --data-dir /tmp/cass_bench_data_isolated --json\n```\n\nObserved:\n- `conversations=3000`, `messages=36000`\n- internal `elapsed_ms ≈ 1701`\n- wall ≈ `1.73s`\n- max RSS ≈ `287MB`\n\n### 3.3 Baseline search (two distinct notions of “latency”)\n\nImportant nuance:\n- `cass` CLI is a *one-shot process*. If you run 200 searches as 200 processes, the cost of **opening Tantivy** dominates.\n- In the **TUI**, `SearchClient` stays open, so the relevant metric is **steady-state query latency**.\n\nWe measured “process-per-search” as a proxy for automation workflows and saw two regimes:\n- steady-state query work (single-digit ms) exists, but can be hidden by cold-open costs (tens of ms) in one-shot CLI.\n\nAction item for future rounds:\n- split measurement into:\n  - `open_ms` (open reader/index/db)\n  - `query_ms` (actual query execution)\n\n---\n\n## 3.4) Baseline workload + metrics (post-change, with p50/p95/p99)\n\n### 3.4.1 Indexing (11 runs; fresh data-dir each run)\n\nCommands (one run; repeated 11× with different `--data-dir`):\n```bash\n/usr/bin/time -v env \\\n  HOME=/tmp/cass_bench_home \\\n  XDG_CONFIG_HOME=/tmp/cass_bench_home/.config \\\n  XDG_DATA_HOME=/tmp/cass_bench_home/.local/share \\\n  XDG_CACHE_HOME=/tmp/cass_bench_home/.cache \\\n  CODEX_HOME=/tmp/cass_bench_codex \\\n  CASS_IGNORE_SOURCES_CONFIG=1 \\\n  CODING_AGENT_SEARCH_NO_UPDATE_PROMPT=1 \\\n  ./target/release/cass --color=never \\\n  index --full --force-rebuild --data-dir /tmp/cass_bench_data_isolated_round1_idx_run_XX --json\n```\n\nCorpus (same as pre-change):\n- `conversations=3000`, `messages=36000`\n\nResults (N=11; nearest-rank percentiles):\n- `elapsed_ms`: p50=1601, p95=1601, p99=1601 (min=1600, max=1601, mean=1600.91)\n- wall (ms): p50=1635, p95=1638, p99=1638 (min=1633, max=1638, mean=1634.91)\n- throughput (messages/s): p50=22485.95, p95=22500.00, p99=22500.00 (min=22485.95, max=22500.00, mean=22487.22)\n- peak RSS (kB): p50=295492, p95=297260, p99=297260 (min=292552, max=297260, mean=295220.36)\n\n### 3.4.2 Search latency (one-shot CLI process; 200 runs per query)\n\nCommand template (repeat 200× per query, discarding stdout except for parsing `_meta.elapsed_ms`):\n```bash\n./target/release/cass --color=never \\\n  search \"<QUERY>\" \\\n  --robot-meta --robot-format compact \\\n  --fields minimal --limit 3 \\\n  --data-dir /tmp/cass_bench_data_isolated_after_round1_sample\n```\n\nResults (N=200 each;

In this session, recording new perf traces is blocked (`perf_event_paranoid=4`), but **existing** perf captures from earlier runs are available under `/tmp/` and can be analyzed with `sudo perf report ...`.\n\n#### 4.1.1 Indexing CPU hotspots (from existing perf capture)\n\nCapture artifact:\n- `/tmp/cass_perf_index_root.data`\n\nReport command:\n```bash\nsudo perf report --stdio --no-children -i /tmp/cass_perf_index_root.data\n```\n\nTop hotspots by self overhead (excerpt):\n- 2.73% `<tantivy_stacker::expull::ExpUnrolledLinkedListWriter>::write_u32_vint`\n- 2.36% `tantivy::tokenizer::simple_tokenizer::SimpleTokenStream::advance`\n- 2.20% `core::str::iter::CharIndices::next`\n- 2.12% `tantivy::query::bm25::compute_tf_cache`\n- 1.82% `<char>::is_alphanumeric`\n- 1.19% `coding_agent_search::search::tantivy::generate_edge_ngrams`\n- 1.13% `sqlite3VdbeExec`\n\nInterpretation:\n- Tantivy indexing/tokenization dominates;

for “automation workflows” this argues for (a) minimizing stored-field loads when output fields don’t require them, and/or (b) a persistent process mode (TUI/daemon) when users care about p95+ query responsiveness rather than “one-shot” invocations.\n\n### 4.3 Allocation profiling (jemalloc + jeprof)\n\nWe used:\n- profiling build: `Cargo.toml` includes `[profile.profiling]` (inherits release, `debug=true`, `strip=false`)\n- runtime allocation capture via jemalloc:\n  - `LD_PRELOAD=/lib/x86_64-linux-gnu/libjemalloc.so.2`\n  - `MALLOC_CONF='prof:true,prof_final:true,prof_accum:true,prof_prefix:/tmp/...'`\n  - analysis via `/usr/bin/jeprof --alloc_space --text --lines ...`\n\nIndexing alloc profile (pre-change) showed:\n- total allocated ≈ `1375.7 MB` for indexing 36k messages\n- biggest buckets were:\n  - general Rust vec growth (`finish_grow`, `try_allocate_in`)\n  - SQLite allocation sites (`sqlite3MemMalloc`)\n  - a notable site inside `TantivyIndex::add_messages` corresponding to repeated `title_prefix` edge-ngrams generation (discussed below)\n\n---\n\n## 5) Opportunity matrix (pre-change)\n\nScoring: higher is better.\n\n| Candidate | Impact | Confidence | Effort | Score | Notes |\n|---|---:|---:|---:|---:|---|\n| Precompute conversation-constant `title_prefix` edge-ngrams once | High | High | Low | 20 | Big alloc churn reducer;

therefore the indexed tokens and stored fields are identical; outputs cannot change.\n\nEquivalence oracle / test:\n- `src/search/tantivy.rs:785` verifies a query matching only the title-prefix matches *every* message doc in a conversation.\n\nAllocation/throughput impact (measured):\n- Indexing total allocated (jemalloc/jeprof) dropped:\n  - `1375.7MB → 1261.1MB` (about 8.3% less total allocated during indexing on the 36k message corpus)\n- Indexing time on the same synthetic corpus improved slightly:\n  - internal `elapsed_ms` from ~`1701` to `1601`\n  - wall from ~`1.73s` to `1.63s`\n\nRollback:\n- revert the precomputation block and restore the per-message `generate_edge_ngrams(title)` call in the loop.\n\n### 6.2 Robot sessions output: skip building unused JSON payloads\n\nWhere:\n- `src/lib.rs:3672` (`output_robot_results`)\n\nWhat changed:\n- if `format == RobotFormat::Sessions`, we:\n  - compute `BTreeSet<&str>` of `result.hits[*].source_path`\n  - print one path per line\n  - `return Ok(())` early\n- this avoids constructing `filtered_hits` JSON (`filter_hit_fields` + truncation + budget clamp) which is unused in sessions format.\n\nIsomorphism proof sketch:\n- sessions output depends only on the set of `source_path` values present in `result.hits`.\n- the optimization only removes intermediate allocations and does not change:\n  - the input set of hits\n  - the `BTreeSet` ordering/uniqueness semantics\n- therefore stdout lines are identical for the same `result.hits`.\n\nEquivalence oracle / test:\n- `tests/cli_robot.rs:334` checks that sessions output equals the unique sorted `source_path` values from compact JSON hits (metamorphic relation across formats).\n\nAllocation impact (measured):\n- sessions search alloc profile dropped:\n  - total allocated `29.4MB → 27.0MB`\n- and the sessions run no longer attributes allocation to `filter_hit_fields` / `clamp_hits_to_budget`.\n\nRollback:\n- remove the early-return and restore the previous match arm behavior (but keep the test; it will still pass).\n\n---\n\n## 7) Additional non-performance correctness fix required during this work\n\nWhile validating connectors and tests, timestamp parsing needed a correctness adjustment:\n- `src/connectors/mod.rs:240` (`parse_timestamp`) now treats typical Unix-seconds ranges as seconds and multiplies by 1000, avoiding misclassification of small millisecond-ish values.\n- connector tests updated accordingly (`src/connectors/amp.rs`, `src/connectors/cline.rs`).\n\nThis is not a perf optimization, but it was necessary for correctness and test stability.\n\n---\n\n## 8) Next candidates (do not implement until re-baselined + re-profiled)\n\nThese are “likely” needle-movers, but must be validated with the same baseline/profile/oracle discipline.\n\n### 8.0 Output-field laziness: avoid reading stored fields when output schema doesn’t need them\n\nThis is the highest-confidence “gross inefficiency” hinted by the existing search CPU profile:\n- `StoreReader::read_block` is a top self hotspot in CLI-per-search mode.\n- `strace` shows heavy `openat` + `mmap/munmap` per one-shot search invocation.\n\nHypothesis:\n- For `--fields minimal` / `--fields summary` / `--robot-format sessions`, we can avoid:\n  - loading `content` / `snippet` / `preview` stored fields\n  - highlight/snippet building\n  - large JSON value construction that is immediately dropped\n\nIsomorphism plan:\n- Treat “requested output fields” as the contract.\n- Proof sketch: if a field is not requested, not computing it cannot affect other fields *unless* it affects ordering, scoring, or truncation budgets. Therefore:\n  - ensure ranking/ordering is computed from the same underlying Tantivy scores and sort keys\n  - ensure any truncation budgets are applied only to fields that are actually emitted\n\nOracle plan:\n- Metamorphic tests:\n  - `--fields minimal` results should equal “full hits” projected down to minimal (already done for sessions; generalize to arbitrary field lists).\n  - For a fixed index, verify hit ordering is identical between “full” and “minimal” modes.\n\nImplementation sketch (minimal diff):\n- Thread “requested fields” into `SearchClient::search` so retrieval/materialization is conditional.\n- Keep query execution + top-doc collection identical; only change the “hydrate hits” step.\n\nRollback:\n- retain old “always hydrate full hit then filter” path behind an env var, so we can bisect regressions quickly.\n\n### 8.1 Indexer peak RSS: stream scan → ingest with bounded backpressure\n\nProblem:\n- `src/indexer/mod.rs` currently collects `pending_batches: Vec<(&str, Vec<NormalizedConversation>)>` across all connectors before ingesting.\n- This can materialize the entire corpus in memory during indexing, increasing peak RSS and risking tail latency spikes.\n\nHypothesis:\n- streaming ingestion (per-connector or chunked) should reduce peak RSS substantially.\n\nIsomorphism risk:\n- ordering and tie-breaking could change if ingestion becomes interleaved differently.\n- If any downstream logic relies on insert order (e.g., dedupe winner selection, stable sort keys), outputs could change.\n\nOracle plan:\n- Define deterministic tie-break rules (if not already explicit) and enforce them.\n- Add metamorphic tests:\n  - indexing in “batch” vs “stream” mode yields identical search results for a suite of fixed queries on the same fixture corpus.\n\nImplementation sketch (minimal diff):\n- Keep connector scanning parallel, but stream conversations over a bounded channel to a single ingest worker.\n- Apply backpressure so scanning cannot outpace ingest.\n\nRollback:\n- gated behind a feature flag/env var to allow quick revert without deleting code.\n\n### 8.2 SQLite N+1-ish overhead: cache `ensure_agent/ensure_workspace` per batch\n\nProblem:\n- `persist_conversations_batched` calls `ensure_agent` + `ensure_workspace` for each conversation, which performs SQL `INSERT ... ON CONFLICT` then `SELECT id`.\n- On large corpora this can become significant overhead.\n\nIsomorphism:\n- safe if and only if:\n  - resulting IDs are identical\n  - transaction boundaries and uniqueness semantics remain identical\n\nOracle plan:\n- Compare DB row counts and key sets after indexing the same corpus with and without caching.\n- Keep deterministic `slug/path → id` mapping semantics.\n\nImplementation sketch:\n- Build local `HashMap<String, i64>` for agent IDs and `HashMap<PathBuf, i64>` for workspace IDs during the batch loop.\n\n### 8.3 Wildcard search CPU: cache compiled regex/dfa for repeated patterns\n\nProblem:\n- perf showed meaningful CPU in regex DFA construction for `RegexQuery::from_pattern` during substring/suffix wildcard searches.\n\nIsomorphism considerations:\n- caching must not change which patterns are built, nor their semantics.\n- must be careful with field selection and escaping rules.\n\nOracle plan:\n- For a fixed index, ensure repeated wildcard queries produce identical hits and ordering across many runs.\n- Add tests that validate escaping behavior is unchanged.\n\nImplementation sketch:\n- A small LRU mapping `(<field>, <pattern>) -> Arc<RegexQuery>` or a tantivy_fst regex object (depending on API).\n- Bound size to prevent memory blowups.\n\n### 8.4 SQLite indexing throughput: reuse prepared statements for hot paths (FTS + message inserts)\n\nEvidence:\n- CPU profiling shows non-trivial time in SQLite parsing/execution (`sqlite3Parser`, `sqlite3VdbeExec`, `fts5*` call stacks).\n- The current persistence code uses many repeated `execute(...)` calls in tight loops, which can imply “prepare/parse” overhead per row unless statements are cached.\n\nHypothesis:\n- Reusing `rusqlite::Statement` (or `prepare_cached`) for the highest-frequency INSERTs can reduce CPU and allocator pressure without changing behavior.\n\nIsomorphism proof sketch:\n- SQL text is identical; parameter bindings are identical; transaction boundaries remain identical.\n- Therefore, the resulting rows and their values are identical for the same input batch.\n\nOracle plan:\n- Compare DB counts and key sets (agents/workspaces/conversations/messages/fts tables) after indexing the same fixture corpus.\n- Run search regression tests to confirm identical hit sets and ordering for representative queries.\n\nImplementation sketch (minimal diff):\n- In the batch persistence loop, prepare the hot statements once per transaction/batch and reuse them for all rows.\n- Keep error handling and commit points identical.\n\nRollback:\n- revert to per-call `execute` or gate prepared statements behind an env var (e.g., `CASS_SQLITE_PREPARED=0`).\n\n### 8.5 CLI cold-open latency: separate `open_ms` and `query_ms`\n\nThis isn’t necessarily a code optimization, but it is essential to avoid misleading p50/p95 numbers.\n\nAction plan:\n- Adjust robot meta to report two timings:\n  - `open_ms` for index/db open\n  - `query_ms` for the query itself\n- Keep `elapsed_ms` for backward compatibility only if explicitly desired; otherwise clarify in docs/tests.\n\nIsomorphism:\n- output JSON changes (so not isomorphic) unless gated by a new flag (e.g., `--robot-meta-v2`).\n\n### 8.6 Semantic search hotspot: CVVI linear scan + per-element `f16 -> f32` conversion\n\nEvidence:\n- Criterion: `vector_index_search_50k` is a clear hotspot (see `benches/search_perf.rs`; built with `Quantization::F16`).\n- Code path: `src/search/vector_index.rs`:\n  - `VectorIndex::search_top_k` is a straight O(n) scan over rows with a top-k heap.\n  - `dot_product_f16` converts every component (`f32::from(*x)`) inside the tight loop.\n\nWhy this matters:\n- Semantic search cost scales linearly with row count; on larger corpora, semantic p95 will dominate “hybrid search” responsiveness unless we fix the inner loop.\n\nBaseline characterization (from code):\n- Complexity: O(n × d) mul-adds, plus heap maintenance (k is small, typically 25).\n- Extra overhead for `Quantization::F16`: O(n × d) `f16 -> f32` conversions.\n\nBack-of-envelope bandwidth sanity check (helps decide “compute-bound vs memory-bound”):\n- For `n=50_000`, `d=384`, `Quantization::F16`:\n  - vector bytes read per query ≈ `n × d × 2` = `38.4 MB`\n  - if the bench is ~56ms, that’s ~`686 MB/s`, far below typical memory bandwidth\n- Conclusion: the hot path is plausibly **compute-bound** (dot products + conversion), not DRAM bandwidth-bound.\n\nProposed optimization: pre-convert F16 slab to F32 once (load-time or first-use)\n- For on-disk `Quantization::F16`:\n  - keep file format the same (F16 on disk, compact, mmap-friendly)\n  - on load, decode the slab into a `Vec<f32>` and store `VectorStorage::F32(...)` for search\n\nIsomorphism proof sketch:\n- The current score computes: `sum_i (f32::from(f16_i) * q_i)` in a fixed sequential order.\n- If we precompute `x_i = f32::from(f16_i)` once and then compute `sum_i (x_i * q_i)` with the same accumulation order, each term and each addition is identical → same `score` bitwise → same ordering and outputs.\n\nTrade-off:\n- RAM: doubles vector slab memory versus keeping `f16` in memory (but disk stays compact).\n- Startup: conversion cost moves to load/open; best amortized in persistent clients (TUI), or gated behind a threshold/env var.\n\nImplementation notes (to avoid self-inflicted regressions):\n- Bench uses `VectorIndex::build(..., Quantization::F16, ...)` (in-memory `Vec<f16>`). Production commonly uses `VectorStorage::Mmap` (bounds checks + pointer math). Measure both paths before assuming identical speedups.\n- Before writing any explicit SIMD, check whether LLVM already auto-vectorizes the existing scalar dot product loop for your target:\n  ```bash\n  RUSTFLAGS=\\\"--emit=asm\\\" cargo build --release\n  # inspect dot_product/dot_product_f16 for vector instructions (and confirm it doesn't reorder sums)\n  ```\n\nOracle plan:\n- Unit test: build a small `Quantization::F16` index, compute `search_top_k` results, then run the “pref32” path and assert:\n  - same `(message_id, chunk_idx)` list\n  - same `score` bitwise (strict isomorphism)\n\nRollback:\n- gate behind an env var (example): `CASS_CVVI_F16_PREF32=1` and default it off until proven.\n\n### 8.7 Semantic search throughput: parallel exact scan with deterministic merge\n\nGoal:\n- Reduce semantic p95 on larger CVVI indices while preserving exactness.\n\nApproach (exact + deterministic):\n- Partition rows into chunks and scan in parallel (rayon).\n- For each chunk, compute the chunk’s exact top-k using the same score function and the same total ordering.\n- Merge all chunk-top-k heaps into a final top-k and then `sort_by(score desc, message_id asc)` (same as today).\n\nIsomorphism proof sketch:\n- Each row’s score is computed identically (same arithmetic, same order).\n- Any globally-top-k row must be within the top-k of its own chunk; otherwise at least k rows in that chunk outrank it, contradicting global top-k membership.\n- Final sort uses the same comparator as the current implementation, so ordering and tie-breaking are identical.\n\nOracle plan:\n- Golden test on a fixed small index where we can assert full equality of:\n  - IDs, chunk_idx, and scores\n  - ordering\n- Property test on random small indices: sequential and parallel implementations produce identical ordered outputs for random query vectors.\n\nRollback:\n- feature-flag or env var (example): `CASS_CVVI_PARALLEL=1` with a conservative size threshold (e.g., only parallelize when `rows.len() >= 10_000`).\n\n### 8.8 Embedding canonicalization: streaming + buffer reuse (byte-identical)\n\nEvidence:\n- Criterion shows `canonicalize_long_message` is ~1ms-scale (see `benches/search_perf.rs`), which affects:\n  - semantic indexing (building CVVI)\n  - semantic query embedding (especially in interactive TUI)\n\nCurrent shape (high-level):\n- multiple intermediate `String` allocations: NFC normalization, markdown/code stripping, whitespace normalization, low-signal filtering, truncation.\n\nProposed optimization:\n- keep the required NFC normalization step (needs full-string collection for combining characters)\n- stream the rest in a single pass with a pre-sized output buffer and minimal intermediate allocations\n\nIsomorphism proof sketch:\n- Define canonicalization as a pure function `canon(text) -> String`.\n- Implement `canon_streaming(text)` such that for all inputs, it produces exactly the same output bytes as `canon(text)` (same markdown stripping rules, same whitespace rules, same truncation).\n- If `canon_streaming == canon` byte-for-byte, downstream embeddings and search outputs are unchanged.\n\nOracle plan:\n- Unit: a corpus of representative messages with a golden `sha256(canon(text))` list.\n- Property: randomized inputs (including unicode/combining marks, markdown fences) must satisfy `canon_streaming(text) == canon(text)` exactly.\n\nRollback:\n- keep the old implementation behind a feature flag if needed (`CASS_CANON_STREAMING=0`).\n\n### 8.9 Approximate nearest neighbor (HNSW/IVF/PQ): *not isomorphic*, opt-in only\n\nThis is a “mathy” lever that can be a massive win at large scale, but it is **not** compatible with the strict “same outputs for same inputs” requirement.\n\nIf we ever add it:\n- It must be explicit opt-in (e.g., `--approximate` or `--semantic-mode approx`).\n- It must preserve deterministic tie-breaking and fixed RNG seeds (where applicable) for reproducibility within the approximate regime.\n- It should be scoped behind a separate index structure (don’t silently change the exact CVVI semantics).\n\n---\n\n## 9) Regression guardrails (current + proposed)\n\nCurrent guardrails already present:\n- `tests/robot_perf.rs` enforces latency thresholds for robot help/introspect/etc.\n\nNew guardrails added this round:\n- sessions output metamorphic parity test (`tests/cli_robot.rs:334`)\n- title_prefix matching test (`src/search/tantivy.rs:785`)\n\nProposed guardrails for next round:\n- indexing peak RSS regression test (hard in unit tests; consider `criterion`/bench harness + CI artifact collection).\n- wildcard regex query build overhead budget via a micro-benchmark that isolates `RegexQuery::from_pattern`.\n- CI-level benchmark regression checks (opt-in, but high leverage):\n  - run `cargo bench` for key benches (`runtime_perf`, `search_perf`) and compare against a stored baseline\n  - use `critcmp` (Criterion compare tool) with a conservative threshold (e.g., fail if >10% regression)\n\n---\n\n## 10) Commands to validate after any next change\n\nAlways run:\n```bash\ncargo fmt --check\ncargo check --all-targets\ncargo clippy --all-targets -- -D warnings\ncargo test\n```\n\nFor profiling builds:\n```bash\nRUSTFLAGS=\"-C force-frame-pointers=yes\" cargo build --profile profiling\n```\n\n---\n\n## 11) Summary of what round 1 accomplished\n\n- Found real hotspots via alloc profiling; avoided “guess optimizations”.\n- Shipped two minimal, provably-isomorphic performance improvements:\n  - reuse title-prefix edge-ngrams per conversation (indexing allocs/time win)\n  - early-return for sessions robot format to avoid unused JSON building (alloc win)\n- Added explicit equivalence tests (metamorphic + direct).\n\nNext round focus should be:\n- peak memory reduction in indexing via streaming + backpressure (but only with strong ordering/tie-break invariants)\n- reducing SQLite overhead in batched persistence via ID caching\n- caching regex compilation in wildcard searches (bounded, deterministic)\n- semantic search wins that preserve exactness (CVVI F16 preconvert + parallel scan)\n"

Estimated ~60% of the ~4.57ms mmap path is F16→F32 conversion overhead; pre-conversion brings the same benchmark to ~1.83ms.\n\n### 2.2 Indexing Baseline (from profiling corpus)\n\nCorpus: 3000 conversations × 12 messages = 36,000 messages\n\nResults (N=11 runs):\n- `elapsed_ms`: p50=1601, p95=1601, p99=1601\n- wall: p50=1635ms, p95=1638ms\n- throughput: p50=22,486 messages/s\n- peak RSS: p50=295 MB\n\n### 2.3 Search Latency (one-shot CLI, N=200 per query)\n\n| Query Type | p50 | p95 | p99 |\n|-----------|-----|-----|-----|\n| exact (`serialize`) | 3ms | 4ms | 4ms |\n| prefix (`ser*`) | 3ms | 3ms | 4ms |\n| suffix (`*ialize`) | 6ms | 7ms | 7ms |\n| substring (`*erial*`) | 9ms | 10ms | 10ms |\n| phrase (`\"serialize benchmark\"`) | 3ms | 4ms | 4ms |\n\n**Important**: CLI-per-search includes cold-open costs. Split into `open_ms` vs `query_ms` for proper analysis.\n\n---\n\n## 3) Profiling Data\n\n### 3.1 CPU Profiling (perf)\n\n**Indexing hotspots** (from `/tmp/cass_perf_index_root.data`):\n- 2.73% `tantivy_stacker::expull::ExpUnrolledLinkedListWriter::write_u32_vint`\n- 2.36% `tantivy::tokenizer::simple_tokenizer::SimpleTokenStream::advance`\n- 2.20% `core::str::iter::CharIndices::next`\n- 1.19% `coding_agent_search::search::tantivy::generate_edge_ngrams`\n- 1.13% `sqlite3VdbeExec`\n\n**Search hotspots** (from `/tmp/cass_perf_search_cli_root.data`):\n- 3.63% `[kernel] clear_page_erms` (page faults / cold-open)\n- 3.44% `tantivy::store::reader::StoreReader::read_block` (stored field reads)\n- 1.16% `tantivy_fst::regex::dfa::Dfa::add`\n- 0.86% `tantivy::query::regex_query::RegexQuery::from_pattern`\n\n### 3.2 I/O Profiling (strace)\n\n**Indexing syscalls** (36k messages):\n- `futex`: 22,689\n- `pwrite64`: 31,443\n- `pread64`: 9,109\n- `openat`: 3,330\n- `fdatasync`: 194\n\n**Search syscalls** (substring wildcard, 200 runs):\n- `openat`: 24,221 (~121/run)\n- `mmap`: 68,089 / `munmap`: 48,409\n- `futex`: 155,597\n- `execve`: 250\n\nInterpretation: One-shot CLI pays substantial open/mmap/munmap per invocation.\n\n### 3.3 Allocation Profiling (jemalloc)\n\nIndexing total allocated: ~1,375 MB for 36k messages\n- Biggest buckets: Rust vec growth, SQLite allocation, edge-ngrams generation\n\n---\n\n## 4) Profiled Hotspots\n\n### 4.1 **Vector Search Linear Scan** (~4.57ms mmap / ~1.83ms preconvert for 50k vectors) — `vector_index.rs:773-803`\n\n```rust\n// O(n) scan over ALL vectors\nfor row in &self.rows {\n    if let Some(filter) = filter && !filter.matches(row) { continue; }\n    let score = self.dot_product_at(row.vec_offset, query_vec)?;  // HOT PATH\n    heap.push(std::cmp::Reverse(ScoredEntry { score, ... }));\n    if heap.len() > k { heap.pop(); }\n}\n```\n\n**Analysis**: Linear O(n×d) where n=50k, d=384. Each iteration:\n- Bounds checking (4 operations)\n- Dot product: 384 multiplications + 383 additions\n- F16→F32 conversion (when using F16 quantization)\n- Heap operations\n\n**Memory Bandwidth Check**: 50k × 384 × 2 bytes = 38.4 MB. In ~4.57ms ≈ 8.4 GB/s; in ~1.83ms ≈ 21.0 GB/s. Modern DDR4 provides 20-50 GB/s. **Conclusion**: mmap path is compute-bound; preconvert pushes closer to bandwidth limits.\n\n### 4.2 **Dot Product Implementation** — `vector_index.rs:1221-1228`\n\n```rust\nfn dot_product(a: &[f32], b: &[f32]) -> f32 {\n    a.iter().zip(b.iter()).map(|(x, y)| x * y).sum()\n}\nfn dot_product_f16(a: &[f16], b: &[f32]) -> f32 {\n    a.iter().zip(b.iter()).map(|(x, y)| f32::from(*x) * y).sum()\n}\n```\n\n**Analysis**: LLVM may auto-vectorize with `-C opt-level=3`, but F16→F32 conversion per element is expensive regardless. Verify auto-vectorization with:\n```bash\nRUSTFLAGS=\"--emit=asm\" cargo build --release\n# Check for vmulps/vaddps (AVX) or mulps/addps (SSE) instructions\n```\n\n### 4.3 **Canonicalization** (951µs for long messages) — `canonicalize.rs:80-95`\n\n```rust\npub fn canonicalize_for_embedding(text: &str) -> String {\n    let normalized: String = text.nfc().collect();  // Allocation\n    let stripped = strip_markdown_and_code(&normalized);  // Line-by-line\n    let whitespace_normalized = normalize_whitespace(&stripped);  // Allocation\n    let filtered = filter_low_signal(&whitespace_normalized);  // Allocation\n    truncate_to_chars(&filtered, MAX_EMBED_CHARS)\n}\n```\n\n**Analysis**: 4+ String allocations per call. Only impacts index-time and semantic query embedding, not lexical search.\n\n### 4.4 **Stored Field Reads** — Tantivy `StoreReader::read_block`\n\nTop hotspot in CLI-per-search mode. For `--fields minimal` or `--robot-format sessions`, we don't need full content/snippet fields.\n\n### 4.5 **Cache Eviction** — `query.rs:971+`\n\nThe eviction loop only runs when over capacity and has early-break logic. **Low priority**.\n\n### 4.6 **RRF Fusion** (251µs) — `query.rs:709+`\n\nAt 251µs, RRF fusion is fast enough. **Low priority**.\n\n---\n\n## 5) Equivalence Oracle\n\nFor optimization verification:\n\n1. **Vector search**: Same (message_id, chunk_idx) set returned. Scores may differ by ~1e-7 relative error due to FP reordering with SIMD - acceptable for ranking.\n2. **RRF fusion**: Deterministic tie-breaking by `SearchHitKey` ordering (already implemented).\n3. **Canonicalization**: Byte-for-byte identical output (test with `content_hash`).\n\nProperty-based tests:\n```\n∀ query, filters: search(q, f).hits.map(|h| h.message_id) ≡ search_optimized(q, f).hits.map(|h| h.message_id)\n∀ text: content_hash(canonicalize(text)) == content_hash(canonicalize_optimized(text))\n```\n\n---\n\n## 6) Opportunity Matrix\n\n| # | Optimization | Impact | Confidence | Effort | Score | p95 Move? |\n|---|-------------|--------|------------|--------|-------|-----------|\n| **1** | Pre-convert F16→F32 slab | 4.57ms → 1.83ms | HIGH | LOW | **9.0** | YES |\n| **2** | SIMD dot product | legacy 30ms → 10-15ms (now shipped; current ~4.57ms mmap) | MEDIUM | LOW | **6.0** | YES |\n| **3** | Parallel vector search | legacy 10-15ms → 2-3ms (now shipped; current ~4.57ms mmap) | HIGH | MEDIUM | **6.0** | YES |\n| **4** | Output-field laziness | Medium | HIGH | MEDIUM | **5.0** | YES |\n| **5** | Wildcard regex caching | Medium | MEDIUM | MEDIUM | **4.0** | YES |\n| **6** | Streaming canonicalize | 951µs → 300µs | HIGH | MEDIUM | 4.0 | NO |\n| **7** | SQLite N+1 caching | Medium | HIGH | MEDIUM | 3.0 | NO |\n| **8** | Streaming backpressure | High | MEDIUM | HIGH | 3.0 | NO |\n| **9** | Approximate NN (IVF/HNSW) | O(n) → O(√n) | LOW | HIGH | 2.0 | DEFER |\n\n**Note on Approximate NN**: CASS is a precision-focused code search tool. Users expect exact results. Approximate search should require explicit opt-in (`--approximate`) if implemented.\n\n---\n\n## 7) Already-Shipped Optimizations (Round 0)\n\n### 7.1 Title-Prefix N-Gram Reuse\n\n**Location**: `src/search/tantivy.rs:261` (`TantivyIndex::add_messages`)\n\n**What changed**: Precompute per-conversation values once:\n- `source_path`, `workspace`, `workspace_original`\n- `title` and `title_prefix = generate_edge_ngrams(title)`\n- `started_at` fallback\n\n**Isomorphism proof**: `generate_edge_ngrams` is pure. Computing it once vs per-message yields identical Tantivy field values.\n\n**Impact**:\n- Indexing alloc: 1,375 MB → 1,261 MB (8.3% reduction)\n- Indexing time: ~1,701ms → 1,601ms\n\n**Equivalence oracle**: `src/search/tantivy.rs:785` verifies title-prefix matching.\n\n### 7.2 Sessions Output Short-Circuit\n\n**Location**: `src/lib.rs:3672` (`output_robot_results`)\n\n**What changed**: For `--robot-format sessions`, compute `BTreeSet<&str>` of `source_path` values and return early, avoiding unused JSON construction.\n\n**Isomorphism proof**: Sessions output depends only on `source_path` set from `result.hits`. Removing intermediate allocations doesn't change the output.\n\n**Impact**: Sessions search alloc: 29.4 MB → 27.0 MB\n\n**Equivalence oracle**: `tests/cli_robot.rs:334` (metamorphic test across formats)\n\n---\n\n## 8) Recommended Optimizations\n\n### **Optimization 1: Pre-Convert F16 Slab at Load Time** — P0\n\n**Current**: F16→F32 conversion per dot product element (384 conversions × 50k vectors per query)\n**Proposed**: Convert entire slab to F32 at `VectorIndex::load()` time\n\n```rust\n// In VectorIndex::load()\nlet vectors = match header.quantization {\n    Quantization::F16 => {\n        let f16_slice = bytes_as_f16(&mmap[slab_start..slab_end])?;\n        let f32_slab: Vec<f32> = f16_slice.iter().map(|v| f32::from(*v)).collect();\n        VectorStorage::F32(f32_slab)  // Store as F32\n    }\n    Quantization::F32 => { /* unchanged */ }\n};\n```\n\n**Isomorphism Proof**:\n- `f32::from(f16)` is injective and deterministic\n- Same conversion happens once at load vs per-query\n- Dot product inputs identical → outputs identical\n\n**Trade-offs**:\n- 2x memory for F16 indices (76.8 MB for 50k × 384 × 4-byte f32 vectors)\n- Loses mmap benefits: currently `VectorStorage::Mmap` enables lazy page loading and OS caching. Converting to heap-allocated `Vec<f32>` requires loading entire slab into memory at startup. For very large indices, consider keeping mmap and adding an optional \"preload\" flag.\n\n**Measured Impact** (search_perf::vector_index_search_50k_loaded, 2026-01-11):\n- `CASS_F16_PRECONVERT=0`: ~4.57ms\n- Default (pre-convert on): ~1.83ms\n- ~60% faster on this workstation\n\n**Rollback**: Env var `CASS_F16_PRECONVERT=0` to keep F16 storage and convert per-query (original behavior).\n\n---\n\n### **Optimization 2: SIMD Dot Product** — P0\n\n**Current**: Scalar loop (may be auto-vectorized)\n**Proposed**: Explicit SIMD using `wide` crate\n\n```rust\nuse wide::f32x8;\n\nfn dot_product_simd(a: &[f32], b: &[f32]) -> f32 {\n    let chunks_a = a.chunks_exact(8);\n    let chunks_b = b.chunks_exact(8);\n    let remainder_a = chunks_a.remainder();\n    let remainder_b = chunks_b.remainder();\n\n    let mut sum = f32x8::ZERO;\n    for (ca, cb) in chunks_a.zip(chunks_b) {\n        let arr_a: [f32; 8] = ca.try_into().unwrap();\n        let arr_b: [f32; 8] = cb.try_into().unwrap();\n        sum += f32x8::from(arr_a) * f32x8::from(arr_b);\n    }\n\n    let mut scalar_sum: f32 = sum.reduce_add();\n    for (a, b) in remainder_a.iter().zip(remainder_b) {\n        scalar_sum += a * b;\n    }\n    scalar_sum\n}\n```\n\n**Isomorphism Note**: SIMD reorders FP operations, causing ~1e-7 relative error. Ranking order is preserved; scores may differ slightly.\n\n**Measured Impact** (2026-01-11, search_perf::vector_index_search_50k, target_critcmp):\n- SIMD disabled (`CASS_SIMD_DOT=0`): ~5.92ms (median; 5.84-6.01ms)\n- SIMD enabled (default): ~19.48ms (median; 16.49-22.72ms)\n- On this host, SIMD is slower (~3.3x). Needs re-test on AVX2/NEON-capable hardware.\n\n**Micro-bench** (runtime_perf::dot_product_* on this host):\n- `dot_product_scalar`: ~260ns\n- `dot_product_simd`: ~39ns\n- ~6-7x faster in isolation, despite end-to-end regression above.\n\n**Expected Impact** (legacy): 2-4x speedup (30ms → 10-15ms). Current 50k bench is ~4.57ms (mmap) / ~1.83ms (preconvert); remaining headroom is smaller.\n\n**Dependency**: Add `wide = \"0.7\"` to Cargo.toml (or latest stable version)\n\n**Rollback**: Env var `CASS_SIMD_DOT=0` to disable SIMD and fallback to scalar.\n\n---\n\n### **Optimization 3: Parallel Vector Search with Rayon** — P1\n\n**Current**: Single-threaded linear scan\n**Proposed**: Parallel scan with thread-local heaps (rayon already in deps)\n\n```rust\nuse rayon::prelude::*;\n\nconst PARALLEL_THRESHOLD: usize = 10_000;\n\npub fn search_top_k_parallel(\n    &self,\n    query_vec: &[f32],\n    k: usize,\n    filter: Option<&SemanticFilter>,\n) -> Result<Vec<VectorSearchResult>> {\n    // Skip parallelism for small indices (Rayon overhead ~1-5µs/task)\n    if self.rows.len() < PARALLEL_THRESHOLD {\n        return self.search_top_k(query_vec, k, filter);\n    }\n\n    let results: Vec<_> = self.rows\n        .par_chunks(1024)\n        .flat_map(|chunk| {\n            let mut local_heap = BinaryHeap::with_capacity(k + 1);\n            for row in chunk {\n                if let Some(f) = filter && !f.matches(row) { continue; }\n                let score = self.dot_product_at(row.vec_offset, query_vec)\n                    .unwrap_or(0.0);\n                local_heap.push(Reverse(ScoredEntry {\n                    score,\n                    message_id: row.message_id,\n                    chunk_idx: row.chunk_idx,\n                }));\n                if local_heap.len() > k { local_heap.pop(); }\n            }\n            local_heap.into_vec()\n        })\n        .collect();\n\n    // Merge thread-local results into final top-k\n    let mut final_heap = BinaryHeap::with_capacity(k + 1);\n    for entry in results {\n        final_heap.push(entry);  // entry is Reverse<ScoredEntry>\n        if final_heap.len() > k { final_heap.pop(); }\n    }\n\n    let mut results: Vec<VectorSearchResult> = final_heap\n        .into_iter()\n        .map(|e| VectorSearchResult {\n            message_id: e.0.message_id,\n            chunk_idx: e.0.chunk_idx,\n            score: e.0.score,\n        })\n        .collect();\n    results.sort_by(|a, b| b.score.total_cmp(&a.score)\n        .then_with(|| a.message_id.cmp(&b.message_id)));\n    Ok(results)\n}\n```\n\n**Isomorphism Proof**:\n- Heap merge is associative\n- Final sort with deterministic tie-breaking (message_id) ensures identical output\n- Parallel execution order doesn't affect result set\n\n**Expected Impact** (legacy): ~4x on 4-core, ~8x on 8-core (10-15ms → 2-3ms). Current 50k bench is ~4.57ms (mmap) / ~1.83ms (preconvert).\n\n**Measured Impact** (2026-01-12, 64-core host, search_perf::vector_index_search_50k_loaded):\n\n| Configuration | Time (p50) | Speedup vs Sequential |\n|---------------|------------|----------------------|\n| Sequential (CASS_PARALLEL_SEARCH=0) | ~100ms (63-135ms) | 1x (baseline) |\n| RAYON_NUM_THREADS=1 | ~6.3ms | ~16x |\n| RAYON_NUM_THREADS=4 | ~2.3ms | ~43x |\n| RAYON_NUM_THREADS=8 | ~1.67ms | ~60x |\n| RAYON_NUM_THREADS=16 | ~1.67ms | ~60x |\n| RAYON_NUM_THREADS=32 | ~1.81ms | ~55x |\n| Default (64 cores) | ~2.05ms | ~49x |\n\n**Analysis**:\n- Excellent scaling up to 8 threads (~60x improvement)\n- Diminishing returns beyond 8-16 threads (memory bandwidth saturation, merge overhead)\n- Single-threaded Rayon (~6.3ms) outperforms pure sequential (~100ms) by 16x due to chunked processing and better cache locality\n- Optimal thread count appears to be 8-16 for this 50k vector workload\n- Full 64-core utilization shows slight regression vs 8-16 cores due to scheduling overhead\n\n**Tuning Note**: Chunk size of 1024 yields ~49 chunks for 50k vectors. Consider 256-512 for better load balancing on many-core systems. Benchmark to find optimal value.\n\n**Dependency Note**: Works best after F16 pre-convert (Optimization 1). With mmap storage, parallel access may cause page fault contention. With pre-converted F32 Vec, all data is in memory and parallelism is fully effective.\n\n**Syntax Note**: Uses `let_chains` (`if let Some(f) = filter && ...`) which requires Rust 1.76+ or nightly.\n\n**Rollback**: Env var `CASS_PARALLEL_SEARCH=0` to disable parallelism and use sequential scan.\n\n---\n\n### **Optimization 4: Output-Field Laziness** — P1\n\n**Current**: Always load all stored fields from Tantivy, then filter\n**Proposed**: Skip stored field reads when output schema doesn't need them\n\n**Problem**: `StoreReader::read_block` is a top hotspot. For `--fields minimal` / `--robot-format sessions`, we don't need `content`, `snippet`, or `preview`.\n\n**Implementation sketch**:\n- Thread \"requested fields\" into `SearchClient::search`\n- Keep query execution + top-doc collection identical\n- Only change the \"hydrate hits\" step\n\n**Isomorphism proof**: If a field is not requested, not computing it cannot affect:\n- Ranking/ordering (computed from Tantivy scores)\n- Other fields (no dependencies)\n\n**Oracle**: Metamorphic tests verifying hit ordering is identical between \"full\" and \"minimal\" modes.\n\n**Rollback**: Env var `CASS_LAZY_FIELDS=0` to disable lazy loading and hydrate all fields.\n\n---\n\n### **Optimization 5: Wildcard Regex Caching** — P2\n\n**Current**: Build `RegexQuery` and DFA for each wildcard query\n**Proposed**: LRU cache of `(<field>, <pattern>) -> Arc<RegexQuery>`\n\n**Problem**: perf shows meaningful CPU in `RegexQuery::from_pattern` + DFA construction for substring/suffix wildcards.\n\n**Isomorphism**: Caching must not change which patterns are built or their semantics.\n\n**Oracle**: Fixed-index tests ensuring repeated wildcard queries produce identical hits.\n\n**Rollback**: Env var `CASS_REGEX_CACHE=0` to disable.\n\n---\n\n### **Optimization 6: Streaming Canonicalization** — P2\n\n**Current**: Multiple String allocations\n**Proposed**: Single-pass with buffer reuse\n\n```rust\npub fn canonicalize_for_embedding_streaming(text: &str) -> String {\n    let mut result = String::with_capacity(text.len().min(MAX_EMBED_CHARS + 100));\n    let normalized: String = text.nfc().collect();\n\n    let mut in_code_block = false;\n    let mut code_lines: Vec<&str> = Vec::new();\n    let mut lang = String::new();\n\n    for line in normalized.lines() {\n        // Process with state machine, append directly to result\n        // Avoid intermediate String allocations\n    }\n\n    result.truncate(MAX_EMBED_CHARS);\n    result\n}\n```\n\n**Impact**: 951µs → ~300µs. Only affects index-time, not query-time.\n\n**Note**: NFC normalization requires full string collection (look-ahead for combining characters), so one allocation remains unavoidable. Savings come from eliminating intermediate `strip_markdown`, `normalize_whitespace`, and `filter_low_signal` allocations.\n\n**Rollback**: Keep original `canonicalize_for_embedding` function; switch via env var `CASS_STREAMING_CANONICALIZE=0`.\n\n---\n\n### **Optimization 7: SQLite N+1 Caching** — P2\n\n**Current**: `ensure_agent` + `ensure_workspace` per conversation (INSERT...ON CONFLICT + SELECT)\n**Proposed**: Cache `HashMap<String, i64>` for agent IDs and workspace IDs per batch\n\n**Isomorphism**: Safe if resulting IDs are identical and transaction boundaries unchanged.\n\n**Oracle**: Compare DB row counts and key sets after indexing same corpus with/without caching.\n\n**Rollback**: Env var `CASS_SQLITE_CACHE=0` to disable ID caching.\n\n---\n\n### **Optimization 8: Streaming Backpressure for Indexing** — P3\n\n**Current**: Collect all `pending_batches` across connectors before ingesting\n**Proposed**: Stream per-connector with bounded channel to single ingest worker\n\n**Risk**: Ordering/tie-breaking could change if ingestion becomes interleaved differently.\n\n**Oracle**: Metamorphic tests: indexing in \"batch\" vs \"stream\" mode yields identical search results.\n\n**Rollback**: Feature flag for quick revert.\n\n---\n\n## 9) Regression Guardrails\n\n### Current Guardrails\n- `tests/robot_perf.rs`: latency thresholds for robot commands\n- `tests/cli_robot.rs:334`: sessions output metamorphic parity\n- `src/search/tantivy.rs:785`: title_prefix matching test\n\n### Proposed Guardrails\n```yaml\n# .github/workflows/perf.yml\n- name: Run benchmarks\n  run: cargo bench --bench search_perf -- --save-baseline pr\n\n- name: Compare to main baseline\n  run: |\n    cargo install critcmp\n    critcmp main pr --threshold 10  # Fail if >10% regression\n```\n\nAdditional:\n- Indexing peak RSS regression test (criterion + CI artifact collection)\n- Wildcard regex build overhead micro-benchmark\n\n---\n\n## 10) Validation Commands\n\nAlways run after changes:\n```bash\ncargo fmt --check\ncargo check --all-targets\ncargo clippy --all-targets -- -D warnings\ncargo test\n```\n\nFor profiling builds:\n```bash\nRUSTFLAGS=\"-C force-frame-pointers=yes\" cargo build --profile profiling\n```\n\nFor benchmark comparison:\n```bash\ncargo bench --bench search_perf -- --save-baseline before\n# Make changes\ncargo bench --bench search_perf -- --save-baseline after\ncargo install critcmp && critcmp before after\n```\n\n---\n\n## 11) Implementation Notes\n\n1. **Verify auto-vectorization first** before implementing explicit SIMD\n2. **Rayon is already a dependency** - parallel search is low-risk\n3. **Mmap path** has additional overhead (pointer arithmetic, bounds checking) not present in benchmarks - production may differ\n4. **Feature flags** recommended for rollback capability\n5. **Each optimization should be one PR** with before/after benchmarks\n6. **CLI latency**: Consider separating `open_ms` vs `query_ms` in robot meta for proper analysis\n\n---\n\n## 12) Summary\n\n### Already Shipped (Round 1)\n| Change | Impact |\n|--------|--------|\n| Title-prefix n-gram reuse | 8.3% less alloc, ~100ms faster indexing |\n| Sessions output short-circuit | 2.4 MB less alloc per search |\n\n### Next Steps\n| Priority | Optimization | Expected Impact |\n|----------|-------------|-----------------|\n| **P0** | Pre-convert F16 | 4.57ms → 1.83ms (bench) |\n| **P0** | SIMD dot product | legacy 30ms → 10-15ms (shipped; current ~4.57ms mmap) |\n| **P1** | Parallel search (Rayon) | legacy 10-15ms → 2-3ms (shipped; current ~4.57ms mmap) |\n| **P1** | Output-field laziness | Medium (cold-open) |\n| **P2** | Wildcard regex caching | Medium (TUI) |\n| **P2** | Streaming canonicalize | 951µs → 300µs |\n| **P2** | SQLite N+1 caching | Medium |\n| **P3** | Streaming backpressure | Peak RSS reduction |\n\n**Achievable speedup on semantic search**: legacy estimate **20-30x** (56ms → 2-3ms).

    "content": "# Plan: Lightweight Semantic & Hybrid Search for CASS\n\n## Executive Summary\n\nThis plan adds **true semantic search** and **hybrid search with RRF reranking** to `cass`, allowing users to cycle through three search modes via a keyboard shortcut:\n\n1. **Lexical** (current default) - BM25 + edge n-grams via Tantivy\n2. **Semantic** - Vector similarity using real ML embeddings (MiniLM)\n3. **Hybrid** - RRF fusion of lexical + semantic results\n\nThe implementation uses `fastembed` (ONNX, CPU-only) for embeddings. To preserve cass's existing privacy/UX contract (\"no surprise network calls\"), **model downloads are consent-gated**:\n\n- By default, cass does **not** add new network calls.\n- The semantic model is downloaded **only** after explicit user action (TUI prompt when switching to Semantic/Hybrid, or `cass models install`).\n- Once installed, semantic search is fully offline.\n\nKey improvements in this revision:\n- Semantic/Hybrid respects existing filters (agent/workspace/source/time) and ranking modes.\n- Vector index is compact + mmap-friendly (f16 default) to keep memory/disk low.\n- Robust model pinning + verification (revision pin + checksums + atomic install).\n- Better hybrid ranking quality (candidate depth, tie-break rules, optional diversity).\n\n---\n\n## Table of Contents\n\n1.

Design Philosophy\n\n### Core Principles\n\n1. **Real Semantic by Default**: Uses actual ML embeddings (MiniLM) - not hash approximations\n2. **No Surprise Network Calls**: Downloads happen only after explicit user opt-in (TUI prompt or CLI command)\n3. **Zero-Drama Setup**: If the user opts in, download/install is automatic with progress + verification\n4. **Fast Iteration**: Semantic search feels responsive (<100ms query time)\n5. **Offline-First**: Once downloaded, no network required; everything runs locally\n6. **Filter Parity**: Semantic/Hybrid must honor the same filters as Lexical (agent/workspace/source/time)\n7. **Reproducible & Safe**: Pinned model revision + SHA256 verification + atomic installs; easy rollback\n\n### Why Real Embeddings Over Hash?\n\nThe beads_viewer Go implementation currently uses only a hash-based embedder (FNV-1a feature hashing), with real sentence-transformers integration planned but not yet implemented. Their code explicitly notes the hash approach \"is not a true 'semantic' model.\"\n\nSince we're in Rust with access to `fastembed-rs` (pure Rust + ONNX, no Python), we can go directly to **real semantic embeddings** as the default. The `AllMiniLML6V2` model:\n- Runs entirely on CPU (no GPU required)\n- ~23MB download (one-time)\n- ~15ms per embedding (fast enough for interactive use)\n- Produces high-quality 384-dimensional semantic vectors\n\n### User Experience Flow\n\n```\nFirst Run (model not installed):\n┌─────────────────────────────────────────────────────────────────┐\n│  cass starts → TUI loads immediately                            │\n│  ↓                                                              │\n│  User toggles Semantic/Hybrid (Alt+S)                           │\n│  → Prompt: \"Semantic requires 23MB model.

Search Mode Architecture\n\n### New SearchMode Enum\n\n```rust\n/// Search algorithm mode - cycles with Alt+S\n#[derive(Clone, Copy, Debug, PartialEq, Eq, Default, Serialize, Deserialize)]\npub enum SearchMode {\n    /// BM25 full-text search via Tantivy (current behavior)\n    #[default]\n    Lexical,\n    /// Vector similarity search using embeddings\n    Semantic,\n    /// RRF fusion of lexical + semantic results\n    Hybrid,\n}\n\nimpl SearchMode {\n    pub fn next(self) -> Self {\n        match self {\n            SearchMode::Lexical => SearchMode::Semantic,\n            SearchMode::Semantic => SearchMode::Hybrid,\n            SearchMode::Hybrid => SearchMode::Lexical,\n        }\n    }\n\n    pub fn label(self) -> &'static str {\n        match self {\n            SearchMode::Lexical => \"Lexical\",\n            SearchMode::Semantic => \"Semantic\",\n            SearchMode::Hybrid => \"Hybrid\",\n        }\n    }\n\n    pub fn short_label(self) -> &'static str {\n        match self {\n            SearchMode::Lexical => \"LEX\",\n            SearchMode::Semantic => \"SEM\",\n            SearchMode::Hybrid => \"HYB\",\n        }\n    }\n}\n```\n\n### Integration with Existing Modes\n\nThe `SearchMode` is **orthogonal** to existing modes:\n- `MatchMode` (Standard/Prefix) - affects lexical query construction\n- `RankingMode` (Recent/Balanced/Relevance/etc.) - affects result ordering\n- `SearchMode` (Lexical/Semantic/Hybrid) - affects which search algorithm(s) run\n\nIn **Semantic** and **Hybrid** modes, `RankingMode` must remain meaningful.\n\n### RankingMode Behavior in Semantic\n\nSemantic similarity uses cosine (dot product of L2-normalized vectors). We map to a non-negative range for blending:\n`sim01 = clamp((sim + 1.0) / 2.0, 0.0..1.0)`\n\nThen apply the same weighting patterns as Lexical:\n- **Recent Heavy**: `score = sim01 * 0.3 + recency * 0.7`\n- **Balanced**: `score = sim01 * 0.5 + recency * 0.5`\n- **Relevance Heavy**: `score = sim01 * 0.8 + recency * 0.2`\n- **Match Quality**: `score = sim01 * 0.85 + recency * 0.15` (semantic has no wildcard penalty)\n- **Date Newest/Oldest**: ignore sim for ordering, but keep sim in metadata for inspection\n\n### RankingMode Behavior in Hybrid\n\nHybrid ordering:\n1. **Primary**: RRF rank fusion score\n2. **Tie-break**: apply RankingMode-specific recency preference\n3. **Tie-break**: higher `max(component_similarity, component_bm25)`\n\nThis makes HYB feel stable and consistent with the existing UX.\n\n---\n\n## 3. Network Policy, Consent, and Model Management\n\nThis feature introduces a new potential network call (model download). To preserve cass's current expectations:\n\n- **Default behavior**: no new network calls.\n- **Download trigger**: only after explicit user action:\n  - TUI: switching to Semantic/Hybrid prompts and offers a single-key \"Download\" action.\n  - CLI: `cass models install` or `cass index --semantic --download-model`.\n- **Headless/CI**: if `TUI_HEADLESS=1` (or no TTY), cass never prompts; semantic remains unavailable unless the user ran an explicit install command.\n- **Hard offline**: `CASS_OFFLINE=1` forbids downloads (and can also gate the existing update check).\n\n### 3.1 New CLI Surface: `cass models`\n\n```bash\n# Show model status (installed, verified, revision, size)\ncass models status [--json]\n\n# Install the default model (consent explicitly given via command)\ncass models install [--model all-minilm-l6-v2] [--mirror <url>] [--json]\n\n# Verify checksums / repair if corrupted\ncass models verify [--repair] [--json]\n\n# Remove model files (reclaim disk)\ncass models remove [--model all-minilm-l6-v2] [-y]\n```\n\n### 3.2 Consent Modes\n\n`CASS_SEMANTIC_AUTODOWNLOAD` is tri-state:\n\n```bash\n# default: ask in TUI only, never in headless\nCASS_SEMANTIC_AUTODOWNLOAD=ask\n\n# always download when user switches to SEM/HYB in TUI (no prompt)\nCASS_SEMANTIC_AUTODOWNLOAD=true\n\n# never download (SEM/HYB requires manual `cass models install`)\nCASS_SEMANTIC_AUTODOWNLOAD=false\n```\n\n### 3.3 Model State Machine\n\n```rust\npub enum ModelState {\n    /// Model not present on disk\n    NotInstalled,\n    /// SEM/HYB requested but user hasn't opted in yet\n    NeedsConsent,\n    /// Download in progress\n    Downloading { progress_pct: u8, bytes_downloaded: u64, total_bytes: u64 },\n    /// Download complete, verifying SHA256\n    Verifying,\n    /// Model ready to use\n    Ready,\n    /// Semantic disabled (offline mode, headless, or policy forbids)\n    Disabled { reason: String },\n    /// Verification failed, will retry or rebuild\n    VerificationFailed { reason: String, retry_count: u8 },\n}\n```\n\n### 3.4 Model Manifest (Reproducibility)\n\nTo make installs reproducible and verifiable, we pin a **Hugging Face revision** (commit hash):\n\n```toml\n# models.manifest.toml (checked into repo)\n[[models]]\nid = \"all-minilm-l6-v2\"\nrepo = \"sentence-transformers/all-MiniLM-L6-v2\"\nrevision = \"e4ce9877abf3edfe10b0d82785e83bdcb973e22e\"  # pinned commit\nfiles = [\n    { name = \"model.onnx\", sha256 = \"abc123...\", size = 22713856 },\n    { name = \"tokenizer.json\", sha256 = \"def456...\", size = 711396 },\n    { name = \"config.json\", sha256 = \"789abc...\", size = 612 },\n]\nlicense = \"Apache-2.0\"\nattribution = \"sentence-transformers/all-MiniLM-L6-v2 by UKPLab\"\n```\n\nIf Hugging Face is blocked, allow optional mirrors:\n```bash\ncass models install --mirror https://internal.mirror/models/\n# or\nCASS_SEMANTIC_MIRROR_URL=https://internal.mirror/models/\n```\n\n### 3.5 Model Selection\n\n**Primary Model**: `sentence-transformers/all-MiniLM-L6-v2`\n- **Dimension**: 384\n- **Size**: ~23MB

Embedding Strategy\n\n### 4.0 What is Embedded (Scope)\n\nTo keep the index small and improve result quality, semantic embeddings are built for:\n- **Roles**: `user` and `assistant` (default)\n- **Excludes**: pure tool ack spam, empty messages, and optionally `system` (configurable)\n- **Provenance fields** are stored alongside embeddings for fast filter parity:\n  - `agent_slug` (or agent_id)\n  - `workspace` (or workspace_id)\n  - `source_id` (local/remote machine id; required for Remote Sources filtering)\n  - `created_at` (ms)\n\nConfig knobs:\n```bash\n# Roles to include in semantic index\nCASS_SEMANTIC_ROLES=user,assistant\n\n# Include tool/system content (off by default)\nCASS_SEMANTIC_INCLUDE_SYSTEM=false\nCASS_SEMANTIC_INCLUDE_TOOLS=false\n```\n\n### 4.1 Embedder Trait\n\n```rust\n/// Trait for generating text embeddings\npub trait Embedder: Send + Sync {\n    /// Generate embedding vector for text\n    fn embed(&self, text: &str) -> Result<Vec<f32>>;\n\n    /// Batch embedding for efficiency\n    fn embed_batch(&self, texts: &[&str]) -> Result<Vec<Vec<f32>>>;\n\n    /// Embedding dimension\n    fn dimension(&self) -> usize;\n\n    /// Embedder identifier (for cache invalidation)\n    fn id(&self) -> &str;\n\n    /// Whether this embedder produces true semantic embeddings\n    fn is_semantic(&self) -> bool;\n}\n```\n\n### 4.2 FastEmbed Embedder (Primary - Real ML)\n\nUsing [fastembed-rs](https://github.com/Anush008/fastembed-rs) for ONNX-based inference:\n\n```rust\nuse fastembed::{TextEmbedding, EmbeddingModel, InitOptions};\n\npub struct FastEmbedder {\n    model: TextEmbedding,\n    model_id: String,\n    dimension: usize,\n}\n\nimpl FastEmbedder {\n    pub fn new(model_path: &Path) -> Result<Self> {\n        let text_embedding = TextEmbedding::try_new(InitOptions {\n            model_name: EmbeddingModel::AllMiniLML6V2,\n            cache_dir: model_path.to_path_buf(),\n            show_download_progress: false, // We handle progress ourselves\n            ..Default::default()\n        })?;\n\n        Ok(Self {\n            model: text_embedding,\n            model_id: \"minilm-384\".to_string(),\n            dimension: 384,\n        })\n    }\n}\n\nimpl Embedder for FastEmbedder {\n    fn embed(&self, text: &str) -> Result<Vec<f32>> {\n        let embeddings = self.model.embed(vec![text], None)?;\n        Ok(embeddings.into_iter().next().unwrap())\n    }\n\n    fn embed_batch(&self, texts: &[&str]) -> Result<Vec<Vec<f32>>> {\n        let texts: Vec<String> = texts.iter().map(|s| s.to_string()).collect();\n        Ok(self.model.embed(texts, None)?)\n    }\n\n    fn dimension(&self) -> usize {\n        self.dimension\n    }\n\n    fn id(&self) -> &str {\n        &self.model_id\n    }\n\n    fn is_semantic(&self) -> bool {\n        true  // Real semantic understanding\n    }\n}\n```\n\n### 4.3 Hash Embedder (Fallback - During Download)\n\nBased on beads_viewer's implementation, using **FNV-1a feature hashing**:\n\n```rust\npub struct HashEmbedder {\n    dimension: usize,  // Default: 384\n}\n\nimpl HashEmbedder {\n    pub fn new(dimension: usize) -> Self {\n        Self { dimension }\n    }\n\n    fn hash_token(token: &str) -> u64 {\n        // FNV-1a hash\n        let mut h: u64 = 0xcbf29ce484222325;

self.dimension];\n\n        for token in tokens {\n            let hash = Self::hash_token(&token);\n            let idx = (hash % self.dimension as u64) as usize;\n            let sign = if (hash >> 63) == 0 { 1.0 } else { -1.0 };\n            vec[idx] += sign;\n        }\n\n        // L2 normalize\n        let norm: f32 = vec.iter().map(|x| x * x).sum::<f32>().sqrt();\n        if norm > 0.0 {\n            for v in &mut vec {\n                *v /= norm;\n            }\n        }\n\n        Ok(vec)\n    }\n\n    fn embed_batch(&self, texts: &[&str]) -> Result<Vec<Vec<f32>>> {\n        texts.iter().map(|t| self.embed(t)).collect()\n    }\n\n    fn dimension(&self) -> usize {\n        self.dimension\n    }\n\n    fn id(&self) -> &str {\n        \"hash-384\"\n    }\n\n    fn is_semantic(&self) -> bool {\n        false  // Not true semantic - just keyword overlap\n    }\n}\n```\n\n**Why hash as fallback**: Hash embeddings provide a reasonable approximation while the ML model downloads:\n- Instantaneous (no model loading)\n- Deterministic (reproducible)\n- Zero network dependency\n- Better than no semantic search at all\n\n**Important**: The TUI clearly indicates when using hash fallback vs real ML:\n- Status bar shows `SEM*` (asterisk) when using hash fallback\n- Shows `SEM` (no asterisk) when using real ML embeddings\n- Toast notification when upgrade completes: \"Semantic search upgraded to ML model\"\n\n### 4.4 Embedder Comparison\n\n| Embedder | Type | Dimension | Speed | Quality | Use Case |\n|----------|------|-----------|-------|---------|----------|\n| **MiniLM (default)** | Real ML | 384 | ~15ms | Excellent | Primary - after download |\n| **Hash (fallback)** | Approximate | 384 | <1ms | Fair | Temporary - during download |\n\n**Alternative Models** (can be configured via env var):\n| Model | Dimension | Size | Speed | Quality |\n|-------|-----------|------|-------|---------|\n| `AllMiniLML6V2` | 384 | ~23MB | Fast | Good |\n| `AllMiniLML12V2` | 384 | ~33MB | Medium | Better |\n| `BGESmallENV15` | 384 | ~33MB | Medium | Best (small) |\n| `BGEBaseENV15` | 768 | ~110MB | Slower | Excellent |\n\n### 4.5 Configuration\n\nEnvironment variables for advanced users:\n```bash\n# Disable auto-download (use hash-only mode)\nCASS_SEMANTIC_AUTODOWNLOAD=false\n\n# Use a different model (requires manual download or will auto-download)\nCASS_SEMANTIC_MODEL=BGESmallENV15\n\n# Force hash-only mode (no ML)\nCASS_SEMANTIC_EMBEDDER=hash\n```\n\n### 4.6 Canonicalization (Critical for Quality + Incremental Correctness)\n\nRaw agent logs often include:\n- Huge code blocks / diffs\n- Tool call transcripts\n- Repeated boilerplate / progress messages\n- Markdown noise\n\nWe define a deterministic `canonicalize_for_embedding()` used for:\n- ML embeddings\n- Content hashing (so unchanged canonical text → unchanged hash)\n\n**Proposed rules** (simple + fast, no ML):\n1. Strip most markdown formatting (keep headings words, inline code text, link text)\n2. Normalize whitespace (collapse runs, trim)\n3. For fenced code blocks:\n   - Keep first N lines + last N lines (defaults: 20/10)\n   - Replace middle with `… [code omitted] …`\n4. Drop known low-signal boilerplate (\"Done.\", \"OK\", empty tool acks)\n\n```rust\npub fn canonicalize_for_embedding(raw: &str) -> String {\n    let mut result = strip_markdown_formatting(raw);\n    result = collapse_code_blocks(&result, 20, 10);\n    result = normalize_whitespace(&result);\n    result = filter_low_signal_content(&result);\n    result.truncate(MAX_EMBED_CHARS);  // Default: 2000\n    result\n}\n\npub fn content_hash(raw: &str) -> [u8; 32] {\n    let canonical = canonicalize_for_embedding(raw);\n    sha256(canonical.as_bytes())\n}\n```\n\nConfig:\n```bash\nCASS_SEM_MAX_CHARS=2000\nCASS_SEM_CODE_HEAD_LINES=20\nCASS_SEM_CODE_TAIL_LINES=10\n```\n\n### 4.7 Chunking Long Messages (Optional, Bounded)\n\nSome messages remain too large even after canonicalization. For those:\n- Create up to **3** chunks (head / middle / tail) with distinct chunk_ids\n- Each chunk becomes an embedding entry referencing the same message_id\n- At render time, hits are collapsed to the message_id (best chunk score wins)\n\nThis improves recall for long \"design doc\" messages without exploding index size.\n\n```rust\npub struct EmbeddingChunk {\n    pub message_id: u64,\n    pub chunk_idx: u8,      // 0, 1, or 2\n    pub text: String,\n    pub content_hash: [u8; 32],\n}\n\npub fn chunk_for_embedding(message_id: u64, canonical: &str, max_chunk_chars: usize) -> Vec<EmbeddingChunk> {\n    if canonical.len() <= max_chunk_chars {\n        return vec![single_chunk(message_id, canonical)];\n    }\n\n    // Create head, middle (if distinct), tail chunks\n    let head = &canonical[..max_chunk_chars];\n    let tail = &canonical[canonical.len().saturating_sub(max_chunk_chars)..];\n\n    let mut chunks = vec![\n        EmbeddingChunk { message_id, chunk_idx: 0, text: head.to_string(), .. },\n        EmbeddingChunk { message_id, chunk_idx: 2, text: tail.to_string(), .. },\n    ];\n\n    // Add middle chunk if content is long enough\n    if canonical.len() > max_chunk_chars * 2 {\n        let mid_start = canonical.len() / 2 - max_chunk_chars / 2;\n        let middle = &canonical[mid_start..mid_start + max_chunk_chars];\n        chunks.insert(1, EmbeddingChunk { message_id, chunk_idx: 1, text: middle.to_string(), .. });\n    }\n\n    chunks\n}\n```\n\n---\n\n## 5. Vector Storage & Index\n\n### 5.1 Vector Index Structure\n\nBinary format (`.cvvi` - Cass Vector Index), revised for compactness, mmap, and filter parity:\n\n```\nHeader:\n  Magic: \"CVVI\" (4 bytes)\n  Version: u16 (little-endian)\n  EmbedderID Length: u16\n  EmbedderID: string (variable)\n  Dimension: u32\n  Quantization: u8              # 0=f32, 1=f16 (default)\n  Count: u32\n  HeaderCRC32: u32              # quick corruption detection\n\nRows (Count repeated, fixed-size):\n  MessageID: u64                # stable SQLite message primary key\n  CreatedAtMs: i64              # for recency/ranking + time filters\n  AgentID: u32                  # small IDs for fast filtering\n  WorkspaceID: u32\n  SourceID: u32                 # remote provenance filter parity\n  ChunkIdx: u8                  # 0 for single-chunk, 0-2 for multi-chunk\n  VecOffset: u64                # offset into contiguous vector slab\n  ContentHash: [32]u8           # SHA-256(canonical content)\n\nVectors slab:\n  [quant; Count * Dimension]    # contiguous for fast streaming dot products\n```\n\n**Key design decisions**:\n- **MessageID instead of (source_path, msg_idx)**: More stable across file moves, remote path mappings, and connector changes\n- **Filter metadata inline**: Enables agent/workspace/source/time filtering without SQLite round-trips per candidate\n- **Contiguous vector slab**: mmap-friendly, enables SIMD-optimized dot products\n\n### 5.2 VectorIndex Implementation\n\n```rust\npub struct VectorIndex {\n    dimension: usize,\n    embedder_id: String,\n    quant: Quantization,               // f16 default, f32 optional\n    rows: Vec<VectorRow>,              // fixed-size metadata per entry\n    vectors: MmapVectors,              // contiguous vector storage (mmap-friendly)\n}\n\npub struct VectorRow {\n    pub message_id: u64,\n    pub created_at_ms: i64,\n    pub agent_id: u32,\n    pub workspace_id: u32,\n    pub source_id: u32,\n    pub chunk_idx: u8,\n    pub vec_offset: u64,               // offset into contiguous vector slab\n    pub content_hash: [u8;

Hybrid Search with RRF\n\n### 6.1 Reciprocal Rank Fusion (RRF)\n\nRRF is the industry-standard method for combining ranked result lists. It's simple, effective, and requires no tuning:\n\n```rust\n/// Reciprocal Rank Fusion constant (standard value)\nconst RRF_K: f32 = 60.0;\n\n/// Calculate RRF score for a document at given rank\nfn rrf_score(rank: usize) -> f32 {\n    1.0 / (RRF_K + rank as f32 + 1.0)\n}\n\n/// Fuse two ranked result lists using RRF\npub fn rrf_fuse(\n    lexical_results: &[SearchHit],\n    semantic_results: &[VectorSearchResult],\n    limit: usize,\n) -> Vec<HybridSearchHit> {\n    let mut scores: HashMap<(String, usize), HybridScore> = HashMap::new();\n\n    // Add lexical scores\n    for (rank, hit) in lexical_results.iter().enumerate() {\n        let key = (hit.source_path.clone(), hit.line_number);\n        let entry = scores.entry(key).or_default();\n        entry.lexical_rank = Some(rank);\n        entry.lexical_score = hit.score;\n        entry.rrf_score += rrf_score(rank);\n        entry.hit = Some(hit.clone());\n    }\n\n    // Add semantic scores\n    for (rank, result) in semantic_results.iter().enumerate() {\n        let key = (result.source_path.clone(), result.msg_idx as usize);\n        let entry = scores.entry(key).or_default();\n        entry.semantic_rank = Some(rank);\n        entry.semantic_score = result.score;\n        entry.rrf_score += rrf_score(rank);\n    }\n\n    // Sort by combined RRF score\n    let mut results: Vec<_> = scores.into_iter().collect();\n    results.sort_by(|a, b| b.1.rrf_score.partial_cmp(&a.1.rrf_score).unwrap());\n\n    results.into_iter()\n        .take(limit)\n        .filter_map(|(_, score)| score.into_hybrid_hit())\n        .collect()\n}\n```\n\n### 6.2 Why RRF?\n\nFrom research and industry practice:\n- **No score normalization needed**: Lexical (BM25) and semantic (cosine) scores are on different scales; RRF uses ranks, not scores\n- **Robust**: Works well across different query types without tuning\n- **Simple**: One parameter (k=60) that rarely needs adjustment\n- **Proven**: Used by Elasticsearch, OpenSearch, Qdrant, Milvus, Azure AI Search\n\n### 6.3 Candidate Depth for Hybrid\n\nWhen running hybrid search, we fetch more candidates than the final result limit:\n\n```rust\npub struct HybridConfig {\n    /// How many lexical candidates to fetch (multiplier of final limit)\n    pub lexical_depth_multiplier: usize,  // Default: 3\n    /// How many semantic candidates to fetch (multiplier of final limit)\n    pub semantic_depth_multiplier: usize, // Default: 3\n}\n\nimpl HybridConfig {\n    pub fn candidate_counts(&self, final_limit: usize) -> (usize, usize) {\n        (\n            final_limit * self.lexical_depth_multiplier,\n            final_limit * self.semantic_depth_multiplier,\n        )\n    }\n}\n```\n\n**Rationale**: RRF fusion works best when both sources contribute meaningful candidates. If we only fetch `limit` candidates from each, we may miss good fusion opportunities. Fetching 3× from each gives room for rank-based scoring to work properly.\n\n### 6.4 Extended Hybrid Scoring (Optional)\n\nFor more sophisticated ranking, we can add additional signals like beads_viewer:\n\n```rust\npub struct HybridWeights {\n    pub text_relevance: f32,    // Default: 0.40\n    pub semantic_similarity: f32, // Default: 0.30\n    pub recency: f32,           // Default: 0.20\n    pub source_diversity: f32,  // Default: 0.10\n}\n\nimpl Default for HybridWeights {\n    fn default() -> Self {\n        Self {\n            text_relevance: 0.40,\n            semantic_similarity: 0.30,\n            recency: 0.20,\n            source_diversity: 0.10,\n        }\n    }\n}\n```\n\n**Weight presets** (like beads_viewer):\n| Preset | Text | Semantic | Recency | Diversity |\n|--------|------|----------|---------|-----------|\n| `balanced` | 0.35 | 0.35 | 0.20 | 0.10 |\n| `semantic-heavy` | 0.20 | 0.50 | 0.20 | 0.10 |\n| `recent-first` | 0.30 | 0.20 | 0.40 | 0.10 |\n\n### 6.5 Diversity (Optional Enhancement)\n\nWhen top results cluster around the same agent/session, users may want source variety. An optional diversity penalty demotes consecutive same-source results:\n\n```rust\npub fn apply_diversity_penalty(\n    results: &mut Vec<HybridSearchHit>,\n    penalty_factor: f32,  // Default: 0.1\n    window_size: usize,   // Default: 3\n) {\n    let mut seen_sources: VecDeque<u32> = VecDeque::with_capacity(window_size);\n\n    for result in results.iter_mut() {\n        let source_id = result.source_id;\n\n        // Count how many times this source appears in recent window\n        let repeat_count = seen_sources.iter().filter(|&&s| s == source_id).count();\n\n        if repeat_count > 0 {\n            // Apply cumulative penalty for repeats\n            result.rrf_score *= 1.0 - (penalty_factor * repeat_count as f32);\n        }\n\n        // Update sliding window\n        if seen_sources.len() >= window_size {\n            seen_sources.pop_front();\n        }\n        seen_sources.push_back(source_id);\n    }\n\n    // Re-sort after penalties\n    results.sort_by(|a, b| b.rrf_score.partial_cmp(&a.rrf_score).unwrap());\n}\n```\n\nConfig:\n```bash\n# Enable diversity penalty (default: off)\nCASS_HYBRID_DIVERSITY=true\nCASS_HYBRID_DIVERSITY_PENALTY=0.1\nCASS_HYBRID_DIVERSITY_WINDOW=3\n```\n\n---\n\n## 7.

Performance Considerations\n\n### 9.1 Embedding Latency\n\n| Embedder | Single Text | Batch (100) | Memory |\n|----------|-------------|-------------|--------|\n| Hash | <1ms | <10ms | ~1MB |\n| AllMiniLML6V2 | ~15ms | ~200ms | ~100MB |\n| BGESmallENV15 | ~20ms | ~300ms | ~150MB |\n\n**Target**: Query-time embedding should complete in <50ms for interactive feel.\n\n### 9.2 Vector Search Latency\n\nWith brute-force dot product (no ANN):\n| Corpus Size | Search Time |\n|-------------|-------------|\n| 10K vectors | ~2ms |\n| 50K vectors | ~10ms |\n| 100K vectors | ~20ms |\n| 500K vectors | ~100ms |\n\nFor typical cass usage (10K-50K messages), brute-force is fast enough.\n\n### 9.3 When to Use HNSW\n\nIf corpus grows beyond 100K messages, consider adding HNSW (Hierarchical Navigable Small World) index:\n- `hnsw` crate in Rust\n- O(log n) search instead of O(n)\n- Tradeoff: Index build time, memory overhead, approximate results\n\n**Decision**: Start with brute-force; add HNSW as opt-in for large corpora.\n\n### 9.4 Caching Strategy\n\n```rust\npub struct SemanticCache {\n    query_cache: LruCache<String, Vec<f32>>,  // Query text -> embedding\n    result_cache: LruCache<(String, SearchMode), Vec<SearchHit>>, // (query, mode) -> results\n}\n```\n\nCache query embeddings since the same query is often run multiple times during a session.\n\n### 9.5 Async Index Building\n\nLike beads_viewer, build semantic index asynchronously:\n1.

Open Questions\n\n### Q1: What if the model download fails repeatedly?\n\n**Decided**: After 3 retries with exponential backoff, fall back to hash-only mode with a clear status indicator (`SEM*`) and periodic retry attempts in the background.\n\n**Open**: Should we show a more prominent warning after N failed attempts? Or just silently continue with hash fallback?\n\n### Q2: Should we pre-download the model on `cass index`?\n\n**Option A**: Only download when TUI starts (current plan)\n- Pro: CLI-only users don't download unnecessarily\n- Con: First TUI launch has download delay\n\n**Option B**: Download during `cass index --full`\n- Pro: Everything ready when TUI opens\n- Con: Slower initial index, larger scope for index command\n\n**Leaning**: Option A, but could add `cass index --download-model` for users who want to pre-download.\n\n### Q3: RRF constant (k) value?\n\n**Standard**: k=60 is the industry default (Elasticsearch, Qdrant, etc.)\n\n**Open**: Should we expose this as a tunable parameter for power users? Or keep it fixed at 60?\n\n**Leaning**: Fixed at 60 initially; add `CASS_RRF_K` env var later if there's demand.\n\n### Q4: Index upgrade notification?\n\nWhen ML model becomes available and the vector index needs rebuilding from hash to ML:\n\n**Option A**: Silently rebuild in background\n**Option B**: Show toast: \"Upgrading semantic index...\"\n**Option C**: Prompt user: \"ML model ready. Rebuild index now? [Y/n]\"\n\n**Leaning**: Option B - informative but non-blocking.\n\n### Q5: Multiple model support?\n\nShould users be able to switch between different models (e.g., MiniLM vs BGE)?\n\n**Current plan**: Single model (MiniLM) for simplicity. Different models have different embedding dimensions, which would require separate vector indices.\n\n**Future**: Could support model selection via env var, with automatic index rebuild when model changes.\n\n---\n\n## Summary\n\nThis plan adds **real semantic search** and **hybrid search with RRF reranking** to cass with:\n\n1. **Auto-download ML model** on first run (~23MB MiniLM, zero-config)\n2. **Graceful degradation** to hash embeddings while model downloads\n3. **Seamless upgrade** when model becomes available\n4. **RRF fusion** for hybrid search (industry-standard k=60)\n5. **Alt+S keyboard shortcut** to cycle modes (LEX → SEM → HYB)\n6. **Clear status indicators** (`SEM` vs `SEM*` for fallback mode)\n7. **Incremental indexing** with content hashing\n8. **Full CLI/robot support** for automation\n\n### Key Differences from beads_viewer\n\n| Aspect | beads_viewer (Go) | cass (Rust) |\n|--------|-------------------|-------------|\n| Default embedder | Hash (only impl) | MiniLM ML (auto-download) |\n| ML support | Planned, not implemented | Built-in via fastembed |\n| Python dependency | Planned for sentence-transformers | None (pure Rust + ONNX) |\n| Model management | Manual | Automatic with verification |\n\nThe implementation goes beyond beads_viewer's current capabilities by shipping with **real semantic embeddings out of the box**, while maintaining the same graceful degradation pattern for offline/constrained environments.\n\n---\n\n## References\n\n- [fastembed-rs](https://github.com/Anush008/fastembed-rs) - Rust embedding library (ONNX-based)\n- [ort](https://github.com/pykeio/ort) - ONNX Runtime for Rust\n- [all-MiniLM-L6-v2](https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2) - Default embedding model\n- [Reciprocal Rank Fusion](https://www.elastic.co/docs/reference/elasticsearch/rest-apis/reciprocal-rank-fusion) - Elasticsearch docs\n- [Qdrant Hybrid Queries](https://qdrant.tech/documentation/concepts/hybrid-queries/) - RRF implementation\n- [beads_viewer](https://github.com/dicklesworthstone/beads) - Reference implementation (Go, hash-only currently)\n"

    "content": "# Plan: Compute Comprehensive Analytics Stats (Tokens, Tools, Roles, Time) in CASS\n\n> Prompt that kicked this off:\n>\n> ```\n> vinchinzu (@vin6716): are you capturing any token metrics on any projects? to benchmark your own inteligence per MM token or $\n> Jeffrey Emanuel (@doodlestein): I guess cass is grabbing all that stuff. I should build those analytics directly into cass.\n> ```\n\n## Executive Summary\n\n`cass` already has the core of a **token + usage analytics pipeline** implemented (fact tables + rollups + ingest + rebuild). The remaining work is to make it coherent, queryable (robot-first CLI + shared query library), and richer across dimensions (models/tools/cost/plan attribution) without sacrificing performance.\n\nThe analytics system should answer questions like:\n\n- Total tokens per **hour/day/week/month** (historical)\n- Breakdowns across **agent types** (codex, claude_code, gemini, cursor, etc.)\n- Breakdowns across **projects/workspaces** (and optionally sources/remotes)\n- Averages like:\n  - tokens per **human message**\n  - tokens per **agent response**\n  - tokens per **tool call**\n  - tokens per **plan**\n- Coverage/quality metrics (what % is real API usage vs estimation)\n\nThe core idea is:\n\n1. Compute **per-message metrics once** at ingest time (or via backfill).\n2. Store those metrics in a **narrow fact table** (no giant content blobs).\n3. Maintain **hourly + daily rollup tables** via batched upserts for O(1) / O(#buckets) time-series queries.\n4. Prefer **API-provided token usage** when available (e.g., Claude Code usage blocks), otherwise fall back to a deterministic estimate (existing `~chars/4` heuristic) while tracking quality explicitly.\n\nNo UI work in this plan; focus is compute + storage.\n\n## Status Update (As Of 2026-02-06)\n\n### Already Implemented In Code (DONE)\n- Token extraction utilities exist in `src/connectors/mod.rs`: `extract_tokens_for_agent()` + per-agent extractors + `normalize_model()`.\n- Track A analytics tables (schema v11) exist and are populated by live ingest:\n  - `message_metrics` (fact table)\n  - `usage_hourly`, `usage_daily` (rollups)\n- Track B analytics tables (schema v10) exist and are populated by live ingest:\n  - `token_usage` (per-message ledger)\n  - `token_daily_stats` (daily rollups)\n  - `model_pricing` (seeded)\n  - conversation summary columns in `conversations` are updated from `token_usage`\n- Live ingest plumbing populates both tracks in `SqliteStorage::insert_conversations_batched`.\n- Rebuild/backfill exists: `SqliteStorage::rebuild_analytics()` rebuilds Track A.\n- Tests already exist for schema/ingest/rebuild correctness (see `src/storage/sqlite.rs` test module).\n\n### Remaining Work (OPEN)\n- Coherency: rebuild/backfill must cover Track B too (or explicitly deprecate it) so drift cannot happen.\n- Query surface: shared `crate::analytics` query library + robot-first CLI (`cass analytics … --json`).\n- Dimensions: model-aware rollups for Track A; per-tool-name detail + rollups.\n- Coverage improvements: Codex `token_count` wiring.\n- Cost estimation: compute USD from `model_pricing` and expose coverage diagnostics.\n- Validation/perf guardrails: fast invariants + drift detection + throughput budgets.\n\n## 1. Existing Code + Why This Is Straightforward\n\nKey facts from the current architecture:\n\n- Connectors normalize conversations into `NormalizedConversation` / `NormalizedMessage` with:\n  - `role` (user/assistant/agent/tool/system/unknown)\n  - `content` (flattened text; tool-use blocks are flattened to `[Tool: X]` markers)\n  - `extra` (raw per-agent JSON payload, often containing rich metadata)\n- Indexer persists into SQLite (`conversations`, `messages`, etc.) and Tantivy.\n- There is already a derived aggregation table `daily_stats` used for fast “sessions/messages/chars per day”.\n- SQLite already stores some heavy JSON blobs in a compact binary form as well:\n  - `conversations.metadata_bin` (MessagePack)\n  - `messages.extra_bin` (MessagePack)\n  This is ideal for **fast analytics backfills** without repeatedly parsing JSON.\n- **Important**: `src/connectors/mod.rs` already contains token extraction utilities:\n  - `extract_claude_code_tokens(extra)` parses Claude Code `message.usage`\n  - `extract_codex_tokens(extra)` parses Codex `event_msg` `token_count` payload\n  - `estimate_tokens_from_content(content, role)` does the deterministic `chars/4` fallback\n  - `extract_tokens_for_agent(agent_slug, extra, content, role)` dispatches + preserves model/provider + tool counts\n\nSo we do not need to invent extraction; the main remaining engineering work is:\n\n- Make Track A + Track B **coherent** under rebuild/backfill (no drift)\n- Add a shared analytics query library + robot-first CLI surface\n- Expand dimensions (models/tools) with rollups so queries stay O(#buckets)\n- Fix ingestion gaps (Codex token_count events coverage)\n\nNote: existing `daily_stats` buckets message counts by **conversation started_at** (because it is updated at conversation insert/append time).\nFor token analytics, we want buckets by **message timestamps** (created_at) so multi-day sessions attribute usage to the correct day/hour.\nThat is why this plan introduces new usage rollups instead of reusing `daily_stats`.\n\n## 2. Definitions (Avoid “One Token Number” Confusion)\n\n### 2.1 Two Kinds of Token Metrics\n\nWe should store and expose **two distinct token notions**:\n\n1. **API usage tokens** (cost/compute relevant):\n   - Comes from agent logs that include provider usage (e.g., Claude Code `message.usage`)\n   - Has components like `input_tokens`, `output_tokens`, and sometimes cache tokens\n   - Represents tokens consumed by the provider call, not just the visible message text\n\n2. **Content tokens (estimated)** (message-size / corpus-volume relevant):\n   - Deterministic estimate from message content using `chars/4` (already implemented)\n   - Applies to every message, across all connectors, uniformly\n   - Useful for “tokens per human message” in a consistent way\n\nFor “benchmark intelligence per MM token or $”, API usage tokens are what we ultimately want.\nFor per-message and per-role averages across heterogeneous agents, content-token estimates are often more stable.\n\n### 2.2 Time Buckets\n\nUse integer bucket ids for compactness and index efficiency:\n\n- `hour_id`: hours since 2020-01-01 00:00:00 UTC\n- `day_id`: days since 2020-01-01 00:00:00 UTC (already used by `daily_stats`)\n\nWeeks/months can be computed from days quickly, but we can also materialize them later if needed.\n\n### 2.3 Dimensions (What We Want to Slice By)\n\nMinimum viable dimensions:\n\n- `agent_slug` (claude_code, codex, cursor, gemini, aider, etc.)\n- `workspace_id` (project path), with a sentinel for unknown\n- `source_id` (local vs remote host/source), already present on conversations\n- `role` (user/assistant/tool/system/other)\n\nOptional expansion dims (phase 2+):\n\n- `model` (raw model string) and normalized (provider/family/tier)\n- `tool_name` (bash/read/etc) for tool-call analytics\n\n## 3. Storage & Schema (SQLite)\n\n### 3.1 Current Schema (Implemented)\n\nThe DB currently contains **two analytics tracks** (both populated by live ingest):\n\n**Track A (schema v11): general message analytics**\n- `message_metrics` (fact table; one row per message_id)\n  - Dimensions: time buckets (hour/day), agent_slug, workspace_id, source_id, role\n  - Metrics: content token estimate + API token components (when available) + tool_call_count + has_plan\n- `usage_hourly`, `usage_daily` (rollups keyed by `(bucket, agent_slug, workspace_id, source_id)`)\n  - Metrics: counts + content-est totals + API totals + coverage counts + plan_message_count\n\n**Track B (schema v10): ledger + model/cost oriented**\n- `token_usage` (per-message ledger keyed by message_id)\n  - Adds: model_name/provider/service_tier, normalized model_family/model_tier, and a placeholder `estimated_cost_usd`\n- `token_daily_stats` (daily rollups keyed by `(day_id, agent_slug, source_id, model_family)`)\n- `model_pricing` (pattern table seeded with pricing rows)\n- conversation token summary columns in `conversations` are updated from `token_usage`\n\n### 3.2 Planned Schema Extensions (Next)\n\nThese additions keep queries fast without scanning raw message content.\n\n**Tools (z9fse.6)**\n- `tool_calls_detail`: per tool invocation (message_id + tool_name + buckets + dims)\n  - Privacy constraint: do not store tool args by default.\n- `tool_usage_hourly` / `tool_usage_daily`: rollups keyed by `(bucket, agent_slug, workspace_id, source_id, tool_name)`\n  - Metrics: invocation_count, message_count_with_tool, api/content token totals attributed to tool-invoking messages, coverage counts.\n\n**Models in Track A (z9fse.11)**\n- Extend `message_metrics` with model fields:\n  - `model_name`, `model_family`, `model_tier`, `provider`\n- Add model rollups (do not change existing usage_* PKs):\n  - `usage_models_daily` (and optionally hourly) keyed by `(bucket, agent_slug, workspace_id, source_id, model_family, model_tier)`\n\n**Cost (z9fse.10)**\n- Compute `token_usage.estimated_cost_usd` from `model_pricing` (effective-date aware + deterministic pattern selection).\n- Sum into `token_daily_stats.estimated_cost_usd` and `conversations.estimated_cost_usd`.\n- Optional (later): add `usd_est_total` columns to Track A rollups (usage_* / tool_* / model_* rollups) so tokens + USD can be queried through one contract.\n\n### 3.3 Why Fact Tables + Rollups?\n\n- Fact tables (`message_metrics`, `token_usage`, `tool_calls_detail`) allow:\n  - rebuilding rollups without touching huge content blobs\n  - correctness debugging (sum-of-facts == rollup invariants)\n  - adding new rollups later without re-parsing agent logs\n- Rollups (`usage_*`, `token_daily_stats`, tool/model rollups) enable:\n  - time-series queries in O(#buckets) with tiny rows\n  - top-N breakdowns without scanning millions of messages\n\n### 3.4 Storage Efficiency Notes\n\n- Keep analytics tables narrow: avoid JSON blobs.\n- Prefer ints + small text dims; add surrogate keys only if a dimension explodes.\n- Avoid row explosion by adding **separate** rollup tables (tools/models) instead of mutating existing primary keys.\n- All derived tables must be rebuildable (see coherency plan in z9fse.13).\n\n## 4. Ingestion Plan (Live, Incremental, Ultra Efficient)\n\n**Status**: Track A + Track B analytics ingestion is already implemented in `SqliteStorage::insert_conversations_batched`.\n\nRemaining ingest work is connector/dimension enrichment:\n- Codex `token_count` wiring (better API coverage)\n- per-tool-name extraction + rollups\n- Track A model rollups\n- cost estimation (USD) computation\n\n### 4.1 Where To Hook In\n\nAll messages flow through SQLite insert points:\n\n- `SqliteStorage::insert_conversation_tree` (new conversation)\n- `SqliteStorage::append_messages` (existing conversation, new messages appended)\n- `SqliteStorage::insert_conversations_batched` / `insert_conversation_in_tx_batched` (fast path used by indexer)\n\nThe batched path is the primary ingestion path and should remain the single place we extend analytics extraction/dims so we do not drift across codepaths.\n\n### 4.2 Metric Extraction Per Inserted Message\n\nWhen a message is inserted (we have `conv.agent_slug`, `conv.source_id`, `workspace_id`, `msg.role`, `msg.content`, `msg.extra_json`):\n\n1. Determine `created_at_ms`:\n   - `msg.created_at` if present\n   - else fallback to `conv.started_at`\n   - else fallback to `SqliteStorage::now_millis()` (last resort; mark as low quality if desired)\n\n2. Compute bucket ids:\n   - `day_id = SqliteStorage::day_id_from_millis(created_at_ms)`\n   - `hour_id = (created_at_ms/1000 - EPOCH_2020_SECS) / 3600` (add helper `hour_id_from_millis`)\n\n3. Compute content metrics:\n   - `content_chars = msg.content.len()`\n   - `content_tokens_est = content_chars / 4`\n\n4. Extract API token usage (or fallback) using existing code:\n   - `usage = connectors::extract_tokens_for_agent(&conv.agent_slug, &msg.extra_json, &msg.content, role_str)`\n   - Persist the fields and also persist `usage.data_source` so we can compute coverage.\n\n5. Heuristic flags:\n   - `has_plan`: cheap heuristic (phase 1):\n     - true if content contains a \"Plan:\" header, \"## Plan\", or starts with \"Plan\" and has numbered steps\n     - intentionally simple; refine later\n\n### 4.3 Batched Rollup Updates (Critical For Speed)\n\nDo NOT upsert per message. Instead:\n\n- While inserting a batch of messages, accumulate deltas in a `HashMap<(bucket_id, agent_slug, workspace_id, source_id), DeltaStruct>`\n- At the end of the transaction, flush to `usage_hourly` and `usage_daily` via **multi-value INSERT with ON CONFLICT DO UPDATE**.\n\nThis is already the core pattern used in the code today:\n- `AnalyticsRollupAggregator` (usage_hourly/usage_daily)\n- `TokenStatsAggregator` (token_daily_stats)\n- batch inserts for fact rows (`message_metrics`, `token_usage`)\n\n### 4.4 “All” Rows vs Group-By\n\nWe have two options:\n\n1. Store only exact dims and do `SUM(...) GROUP BY ...` over rollup table.\n2. Store permutation rows like `agent_slug='all'`, `workspace_id=0 (all)`, `source_id='all'` for instant totals.\n\nRecommendation:\n\n- Start with exact dims only.\n- If we find a real performance need, add permutation rows later using the same “expand” strategy as `daily_stats`.\n\nSumming thousands of rollup rows is already cheap, and it avoids 4x/8x row count inflation.\n\n## 5. Connector Gaps To Fix (For Real API Tokens + Tool Metrics)\n\n### 5.1 Codex token_count events are currently skipped\n\n`extract_codex_tokens` expects `event_msg.payload.type == token_count`, but `CodexConnector::scan` currently ignores those event types.\n\nPlan:\n\n- Update Codex connector parsing so token_count events are not discarded.\n- Best approach: attach token_count data to the nearest preceding assistant response item in `NormalizedMessage.extra` under a `cass` namespace, e.g.:\n  - `extra[\"cass\"][\"token_usage\"][\"output_tokens\"] = ...`\n  - then extend `extract_codex_tokens` to read from that location as well\n\nThis avoids polluting the searchable message stream with token-only synthetic messages.\n\nImportant operational note:\n- Because token_count events have historically been dropped by the connector, old indexed Codex sessions in SQLite generally cannot be “fixed” by analytics rebuild alone.\n- The backfill path is: re-index Codex sources (so assistant messages get updated `extra_*`), then rebuild analytics.\n\n### 5.2 Tool calls and tool results (cross-agent)\n\nWe want “tokens per tool call” and “tool call counts by tool name”.\n\nPhase 1:\n\n- Use what we already extract for Claude Code:\n  - tool_use blocks counted from `/message/content` where `type == tool_use`\n- Store `tool_call_count` and `has_tool_calls` in `message_metrics`\n- Roll up tool counts in hourly/daily tables\n- Compute derived metrics:\n  - `avg_api_tokens_per_tool_call = api_tokens_total / tool_call_count`\n\nPhase 2+:\n\n- Extend extractors for other connectors (Codex tool_call events, Cursor tool calls, etc.)\n- Implement per-tool-name storage + rollups (z9fse.6): `tool_calls_detail` + `tool_usage_hourly`/`tool_usage_daily`, so tool queries are served from rollups (no full scans).\n\n## 6. Backfill / Rebuild Strategy (Historical)\n\nWe need historical tokens across all existing indexed data.\n\n**Status (today)**:\n- Track A rebuild exists: `SqliteStorage::rebuild_analytics()` rebuilds `message_metrics` + `usage_*`.\n- Track B rebuild is missing, but ingest writes `token_usage` + `token_daily_stats` and updates conversation summary columns.\n- Coherency work (track-selectable rebuild + drift detection) is tracked in **z9fse.13**.\n\n### 6.1 Rebuild Principles\n- Analytics tables are **derived**; rebuild must never touch source session files.\n- Rebuild is explicit (do not auto-run on startup).\n- Rebuild must support **track selection** (A/B/all) and record meta so drift can be detected.\n\n### 6.2 Track A Rebuild (Already Implemented)\n- Clear `message_metrics`, `usage_hourly`, `usage_daily` in a transaction.\n- Stream messages joined with dims:\n  - messages + conversations (source_id) + agents (agent_slug) + workspaces (workspace_id)\n  - Prefer decoding `messages.extra_bin` (MessagePack) when present.\n- Compute per-message metrics via `extract_tokens_for_agent()` and insert `message_metrics` (batched).\n- Populate `usage_*` rollups from the fact table.\n\n### 6.3 Track B Rebuild (To Implement)\n- Clear `token_usage` + `token_daily_stats` and reset conversation summary columns.\n- Stream messages and rebuild `token_usage` deterministically (batched insert).\n- Recompute `token_daily_stats` to match ingest semantics (prefer reusing `TokenStatsAggregator`).\n- Update conversation summaries from `token_usage`.\n\n### 6.4 Incremental Maintenance (Watch Mode)\nAfter rebuild, live ingest keeps analytics up-to-date by inserting new fact rows and upserting rollups for new messages only.\n\nNo rescan required.\n\n## 7. Query Surface (Robot-First)\n\nWe want other agents (and future dashboards) to consume analytics without re-implementing SQL.\n\nDesign rules:\n- stdout = JSON data only; stderr = diagnostics\n- buckets are UTC; weeks are ISO-8601 (Mon start)\n- prefer rollups; if a slow path is used, it must be explicit in `_meta`\n\nImplementation plan:\n- Shared query layer: `crate::analytics` (z9fse.12)\n- CLI contract: `cass analytics … --json` (z9fse.3)\n\nCommand tree (v1):\n- `cass analytics status --json`\n- `cass analytics tokens --json`\n- `cass analytics tools --json`\n- `cass analytics models --json`\n- `cass analytics cost --json`\n- `cass analytics rebuild --json`\n- `cass analytics validate --json`\n\nCommon flags (where applicable):\n- time window: `--since/--until`, `--days N`, `--today`, `--week`\n- filters: `--agent`, `--workspace`, `--source`\n- grouping: `--group-by hour|day|week|month`\n- top-N: `--limit N` for breakdown-style commands\n\nCoverage semantics (non-negotiable):\n- report `api_coverage_message_count` and derived `api_coverage_pct`\n- never present USD totals without pricing coverage signals (unknown != 0)\n- always include `_meta` with elapsed_ms and query path (`rollup` vs `slow`)\n\n## 8. “LOTS MORE” Metrics (Designed In, Implement Later)\n\nWith `message_metrics` as a fact table, adding new analytics becomes easy:\n\n- Per-model tokens and cost:\n  - add `dim_price(model_id, price_in, price_out, effective_from, ...)`\n  - compute dollar estimates by joining rollups\n- “Conversation structure” metrics:\n  - average turns per session, tokens per session, tokens per hour of activity\n- Tooling intensity metrics:\n  - tool_calls per 1k tokens\n  - average tool payload size (estimated)\n- Planning metrics:\n  - plan frequency and plan token share\n- “Noise” metrics:\n  - tokens in repeated tool acknowledgments (dedup by content hash)\n- Speed metrics (if timestamps available):\n  - tokens per minute of wall-clock session time\n- Source comparisons:\n  - local vs remote machines\n  - which machine burns the most tokens\n\n## 9. Testing Strategy\n\nThis work is analytics-critical: we need confidence that rollups match facts, rebuild is deterministic, and coverage/drift diagnostics are correct.\n\nAlready implemented tests (see `src/storage/sqlite.rs` test module):\n- schema + migration checks for analytics tables/indexes\n- ingest integration test that populates `message_metrics` + `usage_*` rollups\n- plan heuristic unit tests for `has_plan`\n- Track A rebuild integration test (clear + rebuild + verify)\n\nRemaining additions (tracked primarily in z9fse.8 and z9fse.9):\n1. Connector extraction unit tests\n- Codex token_count attach + extraction path (z9fse.5)\n- Tool-name extraction (z9fse.6)\n- Model normalization edge cases (z9fse.11)\n\n2. Storage + invariants integration tests\n- Track B rebuild + coherency invariants (z9fse.13)\n- Drift injection tests (delete/alter one analytics table) must be detected with actionable output (z9fse.9 / z9fse.3.5)\n- Cost estimation arithmetic + pricing coverage rules (z9fse.10)\n\n3. Robot/e2e shell scripts (tests/e2e/)\n- Index deterministic fixture sessions and assert:\n  - `cass analytics status --json` is sane and stable\n  - `cass analytics tokens --group-by {hour,day,week,month} --json` totals are consistent across granularities\n  - `cass analytics tools/models/cost --json` (once implemented) match fixture expectations and capture rich stderr diagnostics on failure\n\n## 10. Implementation Plan (Aligned to Beads)\n\n### DONE (already in code)\n- `z9fse.1`: analytics schema v11 (`message_metrics`, `usage_hourly`, `usage_daily`)\n- `z9fse.2`: live ingest analytics (fact + rollups populated on insert)\n- `z9fse.4`: Track A rebuild/backfill (`rebuild_analytics()` rebuilds `message_metrics` + `usage_*`)\n- `z9fse.7`: plan detection v1 (`has_plan` + `plan_message_count`)\n\n### NEXT (core coherency + query surface)\n- `z9fse.13`: make Track A + Track B coherent under rebuild/backfill (Track B rebuild + meta + drift signals)\n- `z9fse.12`: shared analytics query library (bucket semantics, week/month aggregation, derived metrics)\n- `z9fse.3.1` + `z9fse.3.2` + `z9fse.3.3`: CLI scaffolding + status + tokens\n- `z9fse.8`: extend tests/e2e as CLI lands\n\n### THEN (dimensions + coverage)\n- `z9fse.5`: Codex token_count wiring (requires re-indexing Codex sources to backfill old sessions)\n- `z9fse.11` + `z9fse.3.6`: model dimension + CLI models\n- `z9fse.6` + `z9fse.3.9`: per-tool-name detail + rollups + CLI tools\n\n### THEN (USD cost)\n- `z9fse.10` + `z9fse.3.7`: cost estimation + CLI cost\n\n### THEN (trust + docs)\n- `z9fse.9` + `z9fse.3.5`: validator/perf guardrails + CLI validate\n- `z9fse.3.8`: robot-docs for analytics\n\n### LATER (plan analytics v2)\n- `z9fse.14`: plan token attribution + heuristic refinement (plan token share, avg tokens per plan)\n\nOut of scope for this plan: ftui analytics dashboards (`2noh9.4.18.*`). Those should consume `crate::analytics` so the numbers match CLI exactly.\n\n## Open Questions\n\n1. Codex `token_count` semantics: output-only, total, or something else? We need to confirm by inspecting real rollout logs.\n2. Should we add a real tokenizer (BPE) for content tokens, or keep `chars/4` for now?\n3. How aggressively should we denormalize dims into rollups (workspace_id + agent_slug + source_id)? Row count could grow; we should measure on a real corpus.\n"

    "content": "# Plan: Comprehensive Token Analytics for CASS\n\n> **Author:** WhiteSnow (Claude Opus 4.6)\n> **Date:** 2026-02-05\n> **Status:** Design proposal — awaiting approval\n> **Origin:** Tweet from @vin6716 asking about token benchmarking per MM token / $\n\n---\n\n## Executive Summary\n\nCASS already indexes conversations from 14+ coding agents into a unified SQLite database. The raw session data from many agents (especially Claude Code) contains **rich per-message token usage data** that is currently being stored in `messages.extra_json` but **never extracted or aggregated**. This plan adds a lightweight analytics layer that extracts, materializes, and pre-aggregates token metrics at indexing time — making any analytics query O(1) rather than requiring expensive full-table scans.\n\nThe design philosophy: **extract once at ingest, aggregate incrementally, query instantly.**\n\n---\n\n## Part 1: What Data Is Actually Available (Empirical Findings)\n\n### Claude Code — GOLD MINE (Verified from live session data)\n\nEvery assistant message contains a full `usage` block:\n\n```json\n{\n  \"message\": {\n    \"model\": \"claude-opus-4-6\",\n    \"usage\": {\n      \"input_tokens\": 3,\n      \"output_tokens\": 10,\n      \"cache_creation_input_tokens\": 7997,\n      \"cache_read_input_tokens\": 19152,\n      \"cache_creation\": {\n        \"ephemeral_5m_input_tokens\": 0,\n        \"ephemeral_1h_input_tokens\": 7997\n      },\n      \"service_tier\": \"standard\",\n      \"inference_geo\": \"not_available\"\n    }\n  },\n  \"requestId\": \"req_011CXq...\",\n  \"timestamp\": \"2026-02-06T01:27:00.429Z\"\n}\n```\n\nUser messages also contain: `thinkingMetadata.maxThinkingTokens`, `version`, `permissionMode`.\n\n**In a single session (this one), 61 assistant messages consumed ~4.7M total tokens.**\n\n### Codex — Token Events Available\n\n```json\n{\"type\":\"event_msg\",\"payload\":{\"type\":\"token_count\",\"tokens\":100}}\n```\n\n### Pi-Agent — Model & Thinking Available\n\nSession header: `{\"provider\":\"anthropic\",\"modelId\":\"claude-3-opus\",\"thinkingLevel\":\"medium\"}`\nContent blocks: `{type: \"thinking\", thinking: \"...\"}`, `{type: \"toolCall\", name: \"...\"}`\n\n### Cursor — Model Names Available\n\n`modelConfig.modelName` or bubble-level `modelType`/`model` field.\n\n### Factory, OpenCode — Model Names Available\n\nBoth capture `message.model` or `modelID`.\n\n### ChatGPT, Aider, Cline, Clawdbot, Vibe, Amp — Limited\n\nNo explicit token data. Must estimate from content length (~4 chars ≈ 1 token).\n\n---\n\n## Part 2: New Schema (Migration V10)\n\n### 2.1 New Table: `token_usage` — Per-Message Token Ledger\n\nThis is the core accounting table.

`TokenExtractor` — Per-Connector Token Parsing\n\nEach connector already stores the raw JSON in `NormalizedMessage.extra`. We add a `TokenExtractor` trait that each connector can implement:\n\n```rust\n/// Extracted token usage from a single message's raw data.\n#[derive(Debug, Clone, Default)]\npub struct ExtractedTokenUsage {\n    pub model_name: Option<String>,\n    pub provider: Option<String>,\n    pub input_tokens: Option<i64>,\n    pub output_tokens: Option<i64>,\n    pub cache_read_tokens: Option<i64>,\n    pub cache_creation_tokens: Option<i64>,\n    pub thinking_tokens: Option<i64>,\n    pub service_tier: Option<String>,\n    pub has_tool_calls: bool,\n    pub tool_call_count: u32,\n    pub data_source: TokenDataSource,\n}\n\n#[derive(Debug, Clone, Default)]\npub enum TokenDataSource {\n    Api,         // Actual token counts from API response\n    #[default]\n    Estimated,   // Estimated from content length\n}\n```\n\n### 3.2 Connector-Specific Extractors\n\n**Claude Code** (highest fidelity):\n```rust\nfn extract_claude_code_tokens(extra: &Value) -> ExtractedTokenUsage {\n    let usage = extra.pointer(\"/message/usage\");\n    let model = extra.pointer(\"/message/model\").and_then(|v| v.as_str());\n    // Extract: input_tokens, output_tokens, cache_read_input_tokens,\n    //          cache_creation_input_tokens, service_tier\n    // Count tool_use blocks in message.content array\n}\n```\n\n**Codex:**\n```rust\nfn extract_codex_tokens(extra: &Value) -> ExtractedTokenUsage {\n    // Check for event_msg with payload.type == \"token_count\"\n    // Extract payload.tokens\n}\n```\n\n**All others (fallback):**\n```rust\nfn estimate_tokens_from_content(content: &str, role: &str) -> ExtractedTokenUsage {\n    // Heuristic: ~4 chars per token (conservative)\n    // For assistant messages: output_tokens = content_len / 4\n    // For user messages: input_tokens = content_len / 4\n    ExtractedTokenUsage {\n        data_source: TokenDataSource::Estimated,\n        ..\n    }\n}\n```\n\n### 3.3 Model Name Normalization\n\n```rust\n/// Normalize raw model strings into (family, tier, provider) tuples.\nfn normalize_model(raw: &str) -> (String, String, String) {\n    // \"claude-opus-4-6\"        → (\"claude\", \"opus\", \"anthropic\")\n    // \"claude-sonnet-4-5-20250929\" → (\"claude\", \"sonnet\", \"anthropic\")\n    // \"claude-haiku-4-5-20251001\"  → (\"claude\", \"haiku\", \"anthropic\")\n    // \"gpt-4o\"                 → (\"gpt\", \"4o\", \"openai\")\n    // \"gpt-4-turbo\"            → (\"gpt\", \"4-turbo\", \"openai\")\n    // \"gemini-2.0-flash\"       → (\"gemini\", \"flash\", \"google\")\n    // \"o3\"                     → (\"gpt\", \"o3\", \"openai\")\n    // Unknown                  → (\"unknown\", raw, \"unknown\")\n}\n```\n\n---\n\n## Part 4: Aggregation Pipeline\n\n### 4.1 `TokenStatsAggregator` — Mirrors Existing `StatsAggregator`\n\nFollow the exact same proven pattern as `StatsAggregator` (storage/sqlite.rs:959):\n\n```rust\n#[derive(Debug, Default)]\npub struct TokenStatsAggregator {\n    // Key: (day_id, agent_slug, source_id, model_family)\n    raw: HashMap<(i64, String, String, String), TokenStatsDelta>,\n}\n\n#[derive(Debug, Default)]\npub struct TokenStatsDelta {\n    pub api_call_count: i64,\n    pub user_message_count: i64,\n    pub assistant_message_count: i64,\n    pub tool_message_count: i64,\n    pub total_input_tokens: i64,\n    pub total_output_tokens: i64,\n    pub total_cache_read_tokens: i64,\n    pub total_cache_creation_tokens: i64,\n    pub total_thinking_tokens: i64,\n    pub grand_total_tokens: i64,\n    pub total_content_chars: i64,\n    pub total_tool_calls: i64,\n    pub estimated_cost_usd: f64,\n    pub session_count: i64,\n}\n```\n\nDuring batch ingestion, for each message with token data:\n1. Extract tokens via `TokenExtractor`\n2. Record into `TokenStatsAggregator`\n3. At commit time, call `expand()` to generate the 5 permutation keys:\n   - `(day, specific_agent, specific_source, specific_model)` — raw entry\n   - `(day, \"all\", specific_source, specific_model)` — all agents\n   - `(day, specific_agent, \"all\", specific_model)` — all sources\n   - `(day, specific_agent, specific_source, \"all\")` — all models\n   - `(day, \"all\", \"all\", \"all\")` — global total\n4.

Run full `rebuild_token_daily_stats()`\n\n---\n\n## Part 7: Efficiency Guarantees\n\n### At Ingest Time\n- Token extraction adds **~1μs per message** (JSON pointer lookup + integer extraction)\n- `TokenStatsAggregator` is in-memory HashMap — zero DB overhead until flush\n- Flush is a single multi-value INSERT (same as existing `StatsAggregator`)\n- Net overhead: **< 1% of total indexing time**\n\n### At Query Time\n- All analytics queries hit **materialized tables** with covering indexes\n- `token_daily_stats` has 4-column composite PK + indexes = O(1) range scans\n- No JOINs needed for time-series queries (everything denormalized)\n- Conversation-level queries use denormalized columns (no subquery needed)\n\n### Storage Overhead\n- `token_usage`: ~100 bytes per message × estimated 500K messages = ~50MB\n- `token_daily_stats`: ~200 bytes per row × estimated 10K rows = ~2MB\n- `model_pricing`: < 1KB\n- Conversation column additions: ~80 bytes per conversation × 20K convos = ~1.6MB\n- **Total: ~54MB** (negligible compared to existing DB + FTS index)\n\n### Memory at Runtime\n- `TokenStatsAggregator` holds at most ~10K entries in memory during batch ingest\n- Each entry: ~200 bytes → ~2MB peak memory during indexing\n- Freed immediately after flush\n\n---\n\n## Part 8: Code Organization\n\nAll new code goes into **existing files** (per AGENTS.md no-file-proliferation rule):\n\n| Component | File | Rationale |\n|-----------|------|-----------|\n| `token_usage` table schema | `src/storage/sqlite.rs` | Migration V10, next to existing migrations |\n| `TokenExtractor` trait + implementations | `src/connectors/mod.rs` | Alongside existing `Connector` trait |\n| Claude Code extractor | `src/connectors/claude_code.rs` | Connector-specific logic stays in connector |\n| Codex extractor | `src/connectors/codex.rs` | Same |\n| Model normalization | `src/connectors/mod.rs` | Shared utility for all connectors |\n| `TokenStatsAggregator` | `src/storage/sqlite.rs` | Next to existing `StatsAggregator` |\n| Conversation summaries | `src/storage/sqlite.rs` | Part of insert pipeline |\n| Robot-mode analytics API | `src/lib.rs` | Where other subcommands are defined |\n| Analytics page data | `src/pages/analytics.rs` | Extends existing analytics bundle |\n| Cost computation | `src/storage/sqlite.rs` | Utility function near `model_pricing` table |\n\n---\n\n## Part 9: Key Design Decisions\n\n### Why a separate `token_usage` table instead of adding columns to `messages`?\n\n1. **Not all messages have token data** — many agents don't provide it. A separate table avoids NULL-heavy columns.\n2. **Denormalization for speed** — `token_usage` includes `agent_id`, `workspace_id`, `day_id` so analytics queries never need JOINs.\n3. **Clean separation of concerns** — message content is for search; token data is for analytics.\n4. **Backfill-friendly** — can be rebuilt from `messages.extra_json` without touching the messages table.\n\n### Why materialized daily stats instead of on-the-fly aggregation?\n\n1. **O(1) vs O(N)** — with 500K+ messages, aggregation queries would take seconds. Materialized: < 1ms.\n2. **Proven pattern** — the existing `daily_stats` table uses this exact approach and it works.\n3. **Incremental updates** — only new data needs to be aggregated, not the entire history.\n\n### Why denormalize model_family into the aggregation key?\n\n1. **Model comparison is the #1 analytics use case** — \"how much did Opus cost vs Sonnet?\"\n2. **Without it, every model query requires a JOIN or subquery** on `token_usage`.\n3. **Cardinality is low** — maybe 10 model families × 365 days × 5 agents × 3 sources = ~55K rows/year. Tiny.\n\n### Why estimate tokens for agents that don't provide them?\n\n1. **Completeness** — analytics dashboards shouldn't have blank rows for Aider/Cline\n2. **Rough is better than nothing** — `~4 chars/token` is a well-known heuristic\n3. **Clearly flagged** — `data_source = 'estimated'` lets consumers filter or weight accordingly\n\n### Why store model pricing in the DB rather than hardcode?\n\n1. **Prices change** — new models launch, prices drop\n2. **User-configurable** — power users can add custom model pricing\n3. **Historical accuracy** — effective_date allows correct cost computation for past data\n4. **Pattern matching** — `model_pattern` supports wildcards for model family grouping\n\n---\n\n## Part 10: Example Outputs\n\n### `cass analytics --summary --robot`\n\n```json\n{\n  \"period\": \"all_time\",\n  \"totals\": {\n    \"conversations\": 12847,\n    \"messages\": 487231,\n    \"api_calls_with_token_data\": 198432,\n    \"grand_total_tokens\": 8_432_198_765,\n    \"total_input_tokens\": 1_234_567_890,\n    \"total_output_tokens\": 987_654_321,\n    \"total_cache_read_tokens\": 5_432_198_765,\n    \"total_cache_creation_tokens\": 777_777_789,\n    \"estimated_total_cost_usd\": 1247.83\n  },\n  \"by_agent\": {\n    \"claude_code\": { \"tokens\": 6_100_000_000, \"cost_usd\": 987.50, \"sessions\": 8432 },\n    \"codex\": { \"tokens\": 1_200_000_000, \"cost_usd\": 145.20, \"sessions\": 2100 },\n    \"cursor\": { \"tokens\": 800_000_000, \"cost_usd\": 89.30, \"sessions\": 1500 },\n    \"gemini\": { \"tokens\": 332_198_765, \"cost_usd\": 25.83, \"sessions\": 815 }\n  },\n  \"by_model_family\": {\n    \"claude\": { \"tokens\": 6_500_000_000, \"cost_usd\": 1050.00, \"calls\": 150000 },\n    \"gpt\": { \"tokens\": 1_500_000_000, \"cost_usd\": 150.00, \"calls\": 35000 },\n    \"gemini\": { \"tokens\": 432_198_765, \"cost_usd\": 47.83, \"calls\": 13432 }\n  },\n  \"averages\": {\n    \"tokens_per_session\": 65612,\n    \"tokens_per_human_message\": 1234,\n    \"tokens_per_agent_response\": 4567,\n    \"tokens_per_tool_call\": 890,\n    \"cost_per_session_usd\": 0.097,\n    \"cache_hit_rate\": 0.73,\n    \"messages_per_session\": 37.9\n  },\n  \"trends_30d\": {\n    \"daily_avg_tokens\": 28_107_329,\n    \"daily_avg_cost_usd\": 41.59,\n    \"daily_avg_sessions\": 428,\n    \"token_growth_rate_pct\": 12.3\n  }\n}\n```\n\n### `cass analytics --by-model --days 7 --robot`\n\n```json\n{\n  \"period\": \"7d\",\n  \"models\": [\n    {\n      \"model\": \"claude-opus-4-6\",\n      \"family\": \"claude\", \"tier\": \"opus\", \"provider\": \"anthropic\",\n      \"total_tokens\": 2_100_000_000,\n      \"input_tokens\": 300_000_000,\n      \"output_tokens\": 250_000_000,\n      \"cache_read_tokens\": 1_400_000_000,\n      \"cache_creation_tokens\": 150_000_000,\n      \"estimated_cost_usd\": 340.50,\n      \"api_calls\": 15000,\n      \"avg_tokens_per_call\": 140000,\n      \"cache_hit_rate\": 0.82\n    },\n    {\n      \"model\": \"claude-haiku-4-5\",\n      \"family\": \"claude\", \"tier\": \"haiku\", \"provider\": \"anthropic\",\n      \"total_tokens\": 500_000_000,\n      \"estimated_cost_usd\": 12.30,\n      \"api_calls\": 8000,\n      \"avg_tokens_per_call\": 62500,\n      \"cache_hit_rate\": 0.65\n    }\n  ]\n}\n```\n\n---\n\n## Part 11: Future Extensions (Not In Scope Now)\n\nThese are explicitly **out of scope** for this plan but would be natural follow-ons:\n\n1. **TUI Dashboard** — Sparkline charts, bar graphs in the terminal\n2. **Budget Alerts** — \"You've spent $X this week\" notifications\n3. **Token Budget Mode** — Set spending limits per project/day\n4. **Export to CSV/Parquet** — For external analysis tools\n5. **Comparative Intelligence Score** — Benchmarking output quality per token across models\n6. **Real-time Streaming** — Watch token usage live as sessions progress\n7. **API Rate Monitoring** — Track requests/minute against rate limits\n8. **Multi-machine Cost Allocation** — Per-machine cost reports\n9. **HTML Pages Integration** — Token analytics in the self-hosted web dashboard\n\n---\n\n## Summary\n\nThis plan adds **comprehensive token analytics** to CASS by:\n\n1. **Extracting** token usage data that's already sitting unused in `messages.extra_json`\n2. **Storing** it in a dedicated `token_usage` table with full denormalization\n3. **Pre-aggregating** into `token_daily_stats` for instant dashboard queries\n4. **Computing costs** using a configurable model pricing table\n5. **Exposing** via `cass analytics --robot` for machine consumption\n\nThe design is:\n- **Zero overhead at query time** (materialized tables)\n- **Negligible overhead at ingest time** (< 1% of indexing time)\n- **~54MB storage** for 500K messages\n- **Incrementally updatable** (no full rebuilds needed)\n- **Backward compatible** (new tables/columns, no breaking changes)\n- **Data-quality aware** (`data_source` distinguishes API data from estimates)\n\nAll code goes into existing files. No new files needed.\n"

Executive Summary\n\nThis proposal describes adding a **secure, encrypted static website export feature** to `cass` (coding-agent-search), enabling users to publish their AI coding agent conversation history to GitHub Pages while protecting sensitive content with client-side encryption.\n\n### Key Innovation\n\nUnlike bv's existing Pages export (which publishes data in plaintext), cass's implementation will use **envelope encryption**:\n- A random **Data Encryption Key (DEK)** encrypts the archive payload (AES-256-GCM)\n- One or more **Key Encryption Keys (KEKs)** derived via Argon2id wrap the DEK for password + recovery unlock\n\nThe static site will be completely opaque until decrypted in the browser—no conversation content, agent names, project paths, or search indexes will be visible to anyone without the decryption key.\n\n### Why This Matters\n\nAI coding agent logs often contain:\n- API keys and secrets (accidentally pasted or logged)\n- Internal codenames and architecture details\n- Debugging sessions with sensitive data\n- Proprietary algorithms and business logic\n\nGitHub Pages can use public repos on Free plans and public/private repos on paid plans—but **the resulting Pages site is always publicly accessible on the internet**. Do NOT assume a private repo makes the Pages site private. Encryption is mandatory for safety, not optional.\n\n---\n\n## 2.

Site title?\n2. **Target Selection**: GitHub Pages / Cloudflare Pages / Local export\n3. **Target Config**: Repo name, visibility, description\n4. **Prerequisites Check**: Verify `gh` or `wrangler` CLI, authentication\n5. **Export Bundle**: Generate database + assets\n6. **Preview**: Optional local HTTP server\n7. **Deploy**: Push to hosting platform\n\n#### Generated Bundle Structure\n\n```\noutput-dir/\n├── index.html              # Main entry point\n├── beads.sqlite3           # Client-side SQLite database\n├── beads.sqlite3.0         # (chunked if large)\n├── beads.sqlite3.1\n├── data/\n│   ├── triage.json         # Precomputed recommendations\n│   ├── insights.json       # Graph metrics\n│   ├── history.json        # Git correlations\n│   └── graph-layout.json   # Force-directed positions\n├── viewer.js               # Main application (100KB)\n├── graph.js                # Graph rendering (121KB)\n├── charts.js               # Dashboard charts\n├── styles.css              # Tailwind CSS\n├── vendor/\n│   ├── sql-wasm.js         # SQLite WASM loader\n│   ├── sql-wasm.wasm       # SQLite WASM binary (640KB)\n│   ├── alpine.min.js       # UI framework\n│   ├── d3.v7.min.js        # Visualization\n│   ├── force-graph.min.js  # Interactive graphs\n│   ├── marked.min.js       # Markdown parsing\n│   └── mermaid.min.js      # Diagram rendering\n└── README.md               # Project overview\n```\n\n#### Frontend Technology Stack\n\n| Purpose | Library | Size |\n|---------|---------|------|\n| Database | sql.js (SQLite WASM) | 640KB |\n| UI Framework | Alpine.js | 44KB |\n| CSS | Tailwind (JIT) | 398KB |\n| Visualization | D3.js v7 | 273KB |\n| Graphs | Force-Graph | 194KB |\n| Markdown | Marked.js | 36KB |\n| Diagrams | Mermaid | 3.2MB |\n| Sanitization | DOMPurify | 20KB |\n\n#### Key Implementation Files (Go)\n\n| File | Purpose | Lines |\n|------|---------|-------|\n| `pkg/export/wizard.go` | Interactive wizard | 850 |\n| `pkg/export/sqlite_export.go` | Database generation | 600+ |\n| `pkg/export/github.go` | GitHub Pages deployment | 400+ |\n| `pkg/export/cloudflare.go` | Cloudflare deployment | 300+ |\n| `pkg/export/viewer_embed.go` | Asset embedding | 200+ |\n\n#### How Data is Embedded\n\n1. **SQLite Database**: Issues, dependencies, metrics exported to `beads.sqlite3`\n2. **JSON Precomputation**: Triage, insights, history computed server-side\n3. **Asset Embedding**: Go's `//go:embed` includes all frontend files in binary\n4. **Title Injection**: `index.html` template has `{{.Title}}` placeholder\n\n#### Deployment Flow (GitHub Pages)\n\n```go\n// Simplified flow from github.go\nfunc deployToGitHub(config Config) error {\n    // 1. Create repository (if needed)\n    gh repo create <name> --public --description \"...\"\n\n    // 2. Clone locally\n    git clone <repo-url> temp-dir\n\n    // 3. Copy bundle contents\n    cp -r bundle/* temp-dir/\n\n    // 4. Commit and push\n    git add -A && git commit -m \"Deploy\" && git push\n\n    // 5. Enable GitHub Pages\n    gh api repos/<owner>/<repo>/pages -X POST \\\n       -f source.branch=main -f source.path=/\n\n    return nil\n}\n```\n\n### Critical Limitation of bv's Approach\n\n**bv exports data in PLAINTEXT**. This works for issue trackers (which are typically not sensitive), but is **completely inappropriate for AI coding agent logs**.\n\n---\n\n## 4. Problem Statement\n\n### The Core Challenge\n\nUsers want to share their AI coding agent history for:\n- **Collaboration**: Team members reviewing debugging approaches\n- **Learning**: Building searchable knowledge bases\n- **Documentation**: Preserving institutional knowledge\n- **Archival**: Long-term storage with easy access\n\n### Why GitHub Pages is Attractive\n\n- **Free hosting** for public repositories\n- **Easy deployment** via git push\n- **Global CDN** for fast access\n- **Custom domains** supported\n- **No server maintenance** required\n\n### Why GitHub Pages is Dangerous for Agent Logs\n\nGitHub Pages is commonly published from public repositories (GitHub Free), and can also be published from private repositories on paid plans. Either way, AI coding agent logs often contain:\n\n| Risk Category | Examples |\n|--------------|----------|\n| **Secrets** | API keys, tokens, passwords (accidentally logged) |\n| **Internal Architecture** | Database schemas, service endpoints, auth flows |\n| **Proprietary Code** | Algorithms, business logic, unreleased features |\n| **Personal Data** | Usernames, emails, file paths with names |\n| **Security Vulnerabilities** | Bug discussions, security fixes before deployment |\n\n### The Solution\n\n**Client-side encryption** that makes the exported data completely opaque:\n\n```\n┌─────────────────────────────────────────────────────────────┐\n│                    Public GitHub Repository                  │\n│  ┌─────────────────────────────────────────────────────────┐│\n│  │ index.html (auth page only)                             ││\n│  │ payload/ (chunked AEAD encrypted database stream)       ││\n│  │   ├── chunk-00000.bin                                   ││\n│  │   ├── chunk-00001.bin                                   ││\n│  │   └── ...                                               ││\n│  │ viewer.js (decryption + UI logic)                       ││\n│  │ vendor/* (libraries)                                     ││\n│  └─────────────────────────────────────────────────────────┘│\n│                                                              │\n│  Without password: See only \"Enter password\" prompt          │\n│  With password: Full search + browsing capability            │\n└─────────────────────────────────────────────────────────────┘\n```\n\n---\n\n## 5. Requirements\n\n### 5.1 Functional Requirements\n\n#### FR-1: Content Selection (Interactive + CLI)\n\n| Filter | Default | CLI Flag | Interactive |\n|--------|---------|----------|-------------|\n| Agents | ALL | `--agents claude-code,codex` | Multi-select checkbox |\n| Time Range | ALL | `--since 2024-01-01 --until 2024-12-31` | Date pickers |\n| Projects | ALL | `--workspaces /path/one,/path/two` | Multi-select with search |\n\n#### FR-1.1: Path Privacy Controls\n\n- Default export MUST avoid embedding absolute local paths unless explicitly requested\n- Support: `--path-mode relative|basename|full|hash` (default: `relative`)\n  - `relative`: Store paths relative to workspace root\n  - `basename`: Store only the filename\n  - `full`: Store absolute paths (with warning)\n  - `hash`: Store opaque SHA256 identifiers\n\n#### FR-2: Encryption (Envelope Encryption)\n\n- **Payload Encryption**: AES-256-GCM using a random per-export DEK (Data Encryption Key)\n- **Key Derivation**: Argon2id (memory-hard, GPU-resistant) to derive KEKs that wrap the DEK\n- **Authentication Methods**:\n  - Password entry (derives KEK that unwraps DEK)\n  - QR code scan of high-entropy recovery secret (creates additional key slot; NOT published with site)\n- **Scope**: ALL data encrypted (database, metadata, search index, pre-computed analytics)\n- **Key Slots**: Support multiple passwords/recovery secrets via envelope encryption\n\n#### FR-3: Static Site Generation\n\n- Self-contained bundle (works offline after initial load)\n- Client-side SQLite via sqlite-wasm (OPFS preferred, in-memory fallback—same runtime)\n- Full-text search capability (dual FTS: natural language + code/path tokenizers)\n- Responsive UI (desktop + mobile)\n- Virtualized rendering for large archives\n- CSP-safe UI layer (no Alpine.js or eval-dependent frameworks)\n\n#### FR-4: Deployment Options\n\n- GitHub Pages (primary target, defaults to `gh-pages` branch)\n- Cloudflare Pages (secondary, supports COOP/COEP headers)\n- Local export (manual deployment)\n\n#### FR-4.1: Hosting Limits & Guardrails (Chunked AEAD is Primary Format)\n\nBecause encrypted archives are not CDN-compressible, we must respect hosting limits:\n\n**GitHub Pages Limits (hard constraints):**\n- Published site size: MUST be ≤ 1 GB\n- Source repo recommended limit: ≤ 1 GB\n- Per-file hard block: 100 MiB; warnings at 50 MiB\n- Soft bandwidth limit: 100 GB/month; deploy timeouts may apply\n\n**Chunked AEAD Architecture:**\n- Payload MUST be stored as independently-authenticated encrypted chunks (chunked AEAD), enabling streaming decryption and bounded memory usage\n- Default chunk size: 8 MiB (configurable). Hard cap: 32 MiB (avoid GitHub >50 MiB warnings)\n- Chunking is ALWAYS used when targeting GitHub Pages (regardless of total size), because it simplifies caching, retries, and file-size compliance\n\n**Compression:**\n- Payload compression BEFORE encryption to minimize transfer size\n- Supported codecs:\n  - `deflate` (default): implemented via streaming JS decompressor (fflate)\n  - `zstd` (optional): better ratio for huge exports, requires wasm decoder loaded post-unlock\n  - `none` (debug/testing only)\n\n#### FR-5: Safety Guardrails\n\n- Unencrypted export requires typing: `I UNDERSTAND AND ACCEPT THE RISKS`\n- Pre-publish summary shows: agents, workspaces, time range, message count\n- Confirmation prompt before any deployment\n\n#### FR-6: Redaction & Share Profiles (NEW)\n\nEncryption protects archives from the public internet—but once you share the password with a teammate, they can see everything. Redaction provides an additional layer of protection for safe sharing:\n\n**Export Profiles:**\n- `private` (default): no redaction; encryption required\n- `team`: redact secrets + usernames + hostnames; keep code/context\n- `public-redacted`: aggressive redaction + path hashing + optional message exclusions\n\n**Redaction Capabilities:**\n- Built-in secret patterns + entropy heuristics (API keys, tokens, passwords)\n- User-provided regex rules (`--redact-regex`, `--redact-replace`)\n- Allowlist/denylist per workspace / agent / conversation\n- Review summary before export (with option to redact, exclude, or continue)\n\n#### FR-7: Attachment Support (Opt-in)\n\nLarge assets (images, PDFs, code snapshots) that agents reference can be included in exports:\n\n**Opt-in Behavior:**\n- Disabled by default to minimize export size\n- Enable with `--include-attachments` or wizard checkbox\n- Size limits: 10MB per file, 100MB total (configurable)\n\n**Storage:**\n- Attachments stored as separate encrypted blobs in `blobs/` directory\n- Each blob named by content hash: `blobs/<sha256>.bin`\n- Reference in messages table via `attachment_refs` JSON array\n\n**Viewer Integration:**\n- Lazy-load attachments on demand (not prefetched)\n- Inline preview for images, syntax-highlighted code\n- Download button for non-previewable types\n\n### 5.2 Non-Functional Requirements\n\n#### NFR-1: Security\n\n- Zero plaintext content in public repository\n- No metadata leakage (file names, sizes reveal nothing)\n- Forward secrecy considerations (optional key rotation)\n\n#### NFR-2: Performance (with explicit security tradeoff)\n\n- Initial page load: < 3 seconds on 3G\n- Search latency: < 100ms after decryption\n- Database size: Efficient chunking for large exports\n- Download size: Payload is compacted (SQLite VACUUM) + compressed (deflate) BEFORE encryption\n- Streaming decrypt: Chunks decrypted and written to OPFS incrementally (bounded memory)\n- OPFS persistence (OPT-IN): Store decrypted database in OPFS for instant subsequent loads. Default is memory-only session for maximum security.\n\n#### NFR-3: Usability\n\n- Wizard experience matching bv's polish\n- Clear error messages for auth failures\n- Progress indicators for long operations\n\n#### NFR-4: Compatibility\n\n- Modern browsers (Chrome 90+, Firefox 88+, Safari 14+)\n- WASM support required\n- JavaScript required (no graceful degradation)\n\n---\n\n## 6.

Mitigations are limited on static hosting; we implement:\n- **TOFU asset-hash warnings**: Store hash of critical assets after first successful unlock; warn loudly if assets change on subsequent visits before accepting a password\n- **Commit-pinned URLs**: Guidance to share commit-pinned URLs/hashes out-of-band for high-trust sharing\n\n**Integrity Fingerprint (recommended hardening):**\n- Generate `site/integrity.json` containing SHA-256 for all public files (index.html, JS/CSS/WASM, config.json, payload chunks)\n- Generate `private/integrity-fingerprint.txt` containing `SHA-256(integrity.json)`\n- Viewer displays the fingerprint before password entry:\n  \"Verify fingerprint matches what the archive owner sent you before unlocking.\"\n- This provides a practical out-of-band verification path (works even on first visit)\n\n```javascript\n// integrity.json structure\n{\n    \"version\": 1,\n    \"generated_at\": \"2025-01-06T12:34:56Z\",\n    \"files\": {\n        \"index.html\": \"sha256-abc123...\",\n        \"viewer.js\": \"sha256-def456...\",\n        \"config.json\": \"sha256-ghi789...\",\n        \"payload/chunk-00000.bin\": \"sha256-jkl012...\",\n        // ...\n    }\n}\n\n// In auth UI (before password entry)\nfunction showIntegrityFingerprint() {\n    const fp = document.getElementById('fingerprint');\n    fp.textContent = `Fingerprint: ${shortFingerprint}`;\n    fp.title = 'Verify this matches what the archive owner sent you';\n}\n```\n\n### 7.2 Cryptographic Design (Envelope Encryption + AAD Binding)\n\nWe use **envelope encryption** to separate the data key from the user's password, with **AAD binding** to cryptographically tie all components together:\n\n```\n┌─────────────────────────────────────────────────────────────┐\n│            Envelope Encryption Model + AAD Binding           │\n├─────────────────────────────────────────────────────────────┤\n│                                                              │\n│  export_id (16 bytes random):                                │\n│    - Unique per export                                       │\n│    - Used as AAD for all AEAD operations                    │\n│    - Binds config.json ↔ payload chunks ↔ key slots         │\n│                                                              │\n│  DEK (Data Encryption Key):                                  │\n│    - Random 256-bit key generated per export                 │\n│    - Encrypts the compressed archive payload chunks          │\n│    - Never stored in plaintext                               │\n│                                                              │\n│  KEK (Key Encryption Key):                                   │\n│    - Derived from password/recovery-secret via Argon2id      │\n│    - Wraps (encrypts) the DEK                               │\n│    - Multiple KEKs = multiple \"key slots\"                   │\n│                                                              │\n│  Benefits:                                                   │\n│    ✓ Password rotation without re-encrypting payload         │\n│    ✓ Multiple passwords (key slots, like LUKS)              │\n│    ✓ Separate recovery secret (QR) from user password       │\n│    ✓ AAD prevents chunk swapping/replay attacks             │\n│                                                              │\n╰─────────────────────────────────────────────────────────────╯\n```\n\n#### Key Derivation (KEK)\n\n**Password slots (human-memorable secrets):**\n```\nPassword → Argon2id → 256-bit KEK\n           ├─ Memory: 64 MB (65536 KB)\n           ├─ Iterations: 3\n           ├─ Parallelism: 4\n           └─ Salt: 16 bytes (random, per key slot)\n```\n\n**Recovery slots (high-entropy secrets):**\n```\nRecoverySecret → HKDF-SHA256 → 256-bit KEK\n                 └─ Salt: 16 bytes (random, per key slot)\n```\n\n**Why two KDFs?**\n- Argon2id is memory-hard (resists GPU/ASIC attacks on weak passwords)\n- Recovery secrets are high-entropy (128+ bits); memory-hard KDF is wasted latency\n- HKDF-SHA256 is fast and sufficient for uniformly random inputs\n- This improves mobile unlock UX when using recovery secrets\n\n**Why Argon2id for passwords?**\n- Memory-hard (resists GPU/ASIC attacks)\n- Hybrid design (resists side-channel + time-memory tradeoffs)\n- Winner of Password Hashing Competition (2015)\n- OWASP recommended\n\n#### Chunk Encryption (DEK → Payload Chunks)\n\n```\nDEK + Nonce + CompressedChunk + AAD(export_id, chunk_index, schema_version)\n    → AES-256-GCM → Ciphertext + AuthTag\n                    ├─ DEK: 256 bits (random per export)\n                    ├─ Nonce: 96 bits (counter-based;

It is a convenience unlock factor that must remain out-of-band (e.g., printed, stored in a password manager, or shown on a second device).\n\n```\n┌─────────────────────────────────────────────────────────────┐\n│  Recovery Secret (QR) creates an additional key slot:        │\n│                                                              │\n│  QR encodes → High-entropy recovery secret (base64)          │\n│            → Argon2id → KEK (recovery slot)                  │\n│            → Unwraps DEK → Decrypts payload                  │\n│                                                              │\n│  The recovery secret is NOT the user's password.             │\n│  This allows separate rotation/revocation.                   │\n│                                                              │\n│  Export output is split into:                                │\n│    - site/    → safe to deploy publicly                     │\n│    - private/ → never deployed (QR image + recovery text)   │\n╰─────────────────────────────────────────────────────────────╯\n```\n\n### 7.3 What Remains Visible\n\nEven with encryption, some information is observable:\n\n| Observable | Mitigation |\n|------------|------------|\n| Bundle exists | Unavoidable (GitHub repo is public) |\n| Approximate size | Pad to fixed sizes (optional) |\n| Last update time | Unavoidable (git history) |\n| That cass was used | Consider generic filenames |\n\n### 7.4 Session Management\n\n```javascript\n// After successful decryption:\nconst SESSION_DURATION = 4 * 60 * 60 * 1000; // 4 hours\n\n// Option 1: Keep key in memory only (most secure)\nwindow.sessionKey = derivedKey; // Lost on refresh\n\n// Option 2: SessionStorage (survives refresh, not tabs)\nsessionStorage.setItem('cass_session', encryptedKeyBlob);\n\n// Option 3: \"Remember me\" with localStorage (least secure)\n// NOT RECOMMENDED for sensitive data\n```\n\n### 7.5 Content Security Policy (Learned from bv)\n\nbv implements strict CSP headers to prevent XSS and code injection. We adopt and strengthen this:\n\n#### CSP Meta Tag (index.html)\n\n```html\n<meta http-equiv=\"Content-Security-Policy\" content=\"\n    default-src 'self';\n    script-src 'self' 'wasm-unsafe-eval';\n    style-src 'self';\n    img-src 'self' data: blob:;\n    font-src 'self';\n    connect-src 'self';\n    worker-src 'self' blob:;\n    object-src 'none';\n    frame-ancestors 'none';\n    form-action 'none';\n    base-uri 'none';\n    upgrade-insecure-requests;\n\">\n\n<!-- Additional hardening (works as meta in static hosting environments) -->\n<meta name=\"referrer\" content=\"no-referrer\">\n<meta http-equiv=\"Permissions-Policy\" content=\"camera=(self), microphone=()\">\n<meta name=\"robots\" content=\"noindex,nofollow\">\n```\n\n#### CSP Directives Explained\n\n| Directive | Value | Purpose |\n|-----------|-------|---------|\n| `default-src` | `'self'` | Only load resources from same origin |\n| `script-src` | `'self' 'wasm-unsafe-eval'` | Allow same-origin JS + WASM compilation |\n| `style-src` | `'self'` | Only external stylesheets (no unsafe-inline) |\n| `img-src` | `'self' data: blob:` | Allow inline images + QR camera preview |\n| `connect-src` | `'self'` | Only fetch from same origin |\n| `worker-src` | `'self' blob:` | Allow service workers |\n| `object-src` | `'none'` | Block plugins (Flash, Java, etc.) |\n| `frame-ancestors` | `'none'` | Prevent embedding in iframes (clickjacking) |\n| `form-action` | `'none'` | Prevent form submissions (no forms in viewer) |\n| `base-uri` | `'none'` | Prevent base tag injection attacks |\n\n#### Why `wasm-unsafe-eval` is Required\n\n- sqlite-wasm and Argon2 WASM require `WebAssembly.compile()` or `WebAssembly.instantiate()`\n- These functions trigger CSP's `eval` restrictions\n- `wasm-unsafe-eval` is a targeted exception for WASM only (not general JS eval)\n- Available in Chrome 97+, Firefox 102+, Safari 16+\n\n#### Why No `unsafe-inline` in style-src\n\nAlpine.js (removed) required `unsafe-inline` for its reactive expressions. With a CSP-safe UI layer:\n- Styles are in external CSS files (Tailwind JIT purged)\n- No inline style attributes generated by JS\n- This makes XSS substantially harder to exploit\n\n#### Input Sanitization\n\nDespite CSP, we still sanitize all user content before rendering:\n\n```javascript\nimport DOMPurify from 'dompurify';\n\n// Optional but recommended: Trusted Types enforcement (if supported).\n// - Prevents accidental assignment of unsanitized HTML into innerHTML sinks.\n// - DOMPurify can be configured to return TrustedHTML.\n// - If enabled, add: require-trusted-types-for 'script' (supported browsers only)\n\n// Configuration matching bv's settings\nconst SANITIZE_CONFIG = {\n    ALLOWED_TAGS: ['p', 'br', 'strong', 'em', 'code', 'pre', 'ul', 'ol', 'li', 'a', 'h1', 'h2', 'h3', 'h4', 'blockquote'],\n    ALLOWED_ATTR: ['href', 'title', 'class'],\n    ALLOW_DATA_ATTR: false,\n    ADD_ATTR: ['target', 'rel'], // For links\n    FORBID_TAGS: ['script', 'style', 'iframe', 'object', 'embed', 'form'],\n    FORBID_ATTR: ['onerror', 'onclick', 'onload', 'onmouseover'],\n};\n\nfunction renderMessage(content) {\n    // Parse Markdown first\n    const html = marked.parse(content);\n    // Then sanitize\n    return DOMPurify.sanitize(html, SANITIZE_CONFIG);\n}\n```\n\n### 7.6 Service Worker for Cross-Origin Isolation + Offline Caching (Encrypted-Only Payload Cache)\n\nGitHub Pages does not allow configuring arbitrary response headers directly, but **COOP/COEP can be applied via a Service Worker** on subsequent loads, enabling cross-origin isolation (SharedArrayBuffer / WASM threads) even on static hosting.\n\nWe adopt the **coi-serviceworker** approach with an **encrypted payload cache** for offline capability:\n\n```javascript\n// sw.js - Cross-Origin Isolation + Offline Caching Service Worker\nconst CACHE_NAME = 'cass-archive-v1';\nconst IMMUTABLE_ASSETS = [\n    './vendor/sqlite3.wasm',\n    './vendor/argon2-wasm.wasm',\n    './vendor/fflate.min.js',\n    './styles.css'\n];\n\n// Encrypted payload can be cached safely (still requires password)\n// Prefetched only when the user opts in (\"Make available offline\")\nconst ENCRYPTED_ASSETS = ['./config.json', './integrity.json'];\n\nself.addEventListener('install', (event) => {\n    event.waitUntil(\n        caches.open(CACHE_NAME).then(cache => cache.addAll(IMMUTABLE_ASSETS))\n    );\n    self.skipWaiting();\n});\n\nself.addEventListener('activate', (event) => {\n    event.waitUntil(self.clients.claim());\n});\n\nself.addEventListener('fetch', (event) => {\n    const url = new URL(event.request.url);\n\n    // Only handle same-origin requests\n    if (url.origin !== location.origin) {\n        return; // Let browser handle cross-origin\n    }\n\n    // For navigation requests, inject COOP/COEP headers\n    if (event.request.mode === 'navigate') {\n        event.respondWith(\n            fetch(event.request).then(response => {\n                const headers = new Headers(response.headers);\n                headers.set('Cross-Origin-Opener-Policy', 'same-origin');\n                headers.set('Cross-Origin-Embedder-Policy', 'require-corp');\n                return new Response(response.body, {\n                    status: response.status,\n                    statusText: response.statusText,\n                    headers\n                });\n            })\n        );\n        return;\n    }\n\n    // Cache-first for immutable assets\n    event.respondWith(\n        caches.match(event.request).then(cached => {\n            return cached || fetch(event.request);\n        })\n    );\n});\n\n// Client → SW message to prefetch encrypted payload for offline use\nself.addEventListener('message', (event) => {\n    if (event.data?.type === 'PREFETCH_ENCRYPTED') {\n        event.waitUntil((async () => {\n            const cache = await caches.open(CACHE_NAME);\n            await cache.addAll(ENCRYPTED_ASSETS);\n            // payload chunk list is discovered from config.json\n            const cfg = await (await fetch('./config.json')).json();\n            await cache.addAll(cfg.payload.files);\n        })());\n    }\n    if (event.data?.type === 'CLEAR_OFFLINE') {\n        event.waitUntil(caches.delete(CACHE_NAME));\n    }\n});\n```\n\n#### Offline Capability via Encrypted Payload Cache\n\nCaching encrypted payload is safe and useful:\n- **Safe**: Encrypted chunks are opaque without the password\n- **Useful**: Enables unlock without network after first download\n- **User-initiated**: Only cached when user clicks \"Make available offline\"\n\n```javascript\n// In viewer.js - UI action to enable offline mode\nasync function enableOfflineMode() {\n    const registration = await navigator.serviceWorker.ready;\n    registration.active.postMessage({ type: 'PREFETCH_ENCRYPTED' });\n    showToast('Downloading for offline access...');\n}\n\nasync function clearOfflineData() {\n    const registration = await navigator.serviceWorker.ready;\n    registration.active.postMessage({ type: 'CLEAR_OFFLINE' });\n    showToast('Offline data cleared');\n}\n```\n\n#### Registration (in viewer.js)\n\n```javascript\n// Register service worker early (relative path for GitHub project pages)\nif ('serviceWorker' in navigator) {\n    navigator.serviceWorker.register('./sw.js', { scope: './' })\n        .then(reg => console.log('SW registered:', reg.scope))\n        .catch(err => console.warn('SW registration failed:', err));\n}\n```\n\n#### Important UX Note: Two-Load Pattern\n\nCross-origin isolation via Service Worker requires a page reload:\n- **First visit**: Installs Service Worker (no COI yet)\n- **Second load** (automatic or prompted refresh): Cross-origin isolated, SharedArrayBuffer available\n\nThe viewer should detect this and prompt for a one-time refresh on first visit.\n\n#### Benefits of COI Service Worker\n\n| Feature | Without COI | With COI |\n|---------|-------------|----------|\n| Argon2 parallelism | Single-threaded (~3-9s) | Multi-threaded (~1-3s) |\n| SharedArrayBuffer | Not available | Available |\n| sqlite-wasm OPFS | Limited | Full support |\n| Offline unlock | Not available | Cached assets work offline |\n\n---\n\n## 8.

For Rust, we use `dialoguer` + `indicatif` + `console` to achieve similar UX:\n\n#### Wizard State Machine\n\n```rust\nuse dialoguer::{Confirm, Input, MultiSelect, Password, Select, theme::ColorfulTheme};\nuse indicatif::{ProgressBar, ProgressStyle, MultiProgress};\nuse console::{style, Term};\n\n#[derive(Debug, Clone)]\npub struct WizardState {\n    // Step 1: Content Selection\n    pub agents: Vec<String>,\n    pub time_range: TimeRange,\n    pub workspaces: Vec<PathBuf>,\n\n    // Step 2: Security\n    pub password: Option<String>,\n    pub generate_qr: bool,\n\n    // Step 3: Site Config\n    pub title: String,\n    pub description: String,\n\n    // Step 4: Deployment\n    pub target: DeployTarget,\n    pub repo_name: Option<String>,\n\n    // Internal\n    pub current_step: usize,\n    pub total_steps: usize,\n}\n\nimpl WizardState {\n    pub fn run_interactive(&mut self) -> Result<(), WizardError> {\n        let term = Term::stdout();\n        let theme = ColorfulTheme::default();\n\n        // Print header\n        self.print_header(&term)?;\n\n        // Step 1: Content Selection\n        self.step_content_selection(&term, &theme)?;\n\n        // Step 2: Security Configuration\n        self.step_security(&term, &theme)?;\n\n        // Step 3: Site Configuration\n        self.step_site_config(&term, &theme)?;\n\n        // Step 4: Deployment Target\n        self.step_deployment(&term, &theme)?;\n\n        // Step 5: Pre-Publish Summary (with confirmation)\n        if !self.step_summary(&term, &theme)? {\n            return Err(WizardError::Cancelled);\n        }\n\n        // Step 6: Export Progress\n        self.step_export(&term)?;\n\n        // Step 7: Deploy\n        self.step_deploy(&term)?;\n\n        Ok(())\n    }\n}\n```\n\n#### Dynamic Content Stats (like bv)\n\n```rust\n/// Fetch live statistics for wizard display\npub struct ContentStats {\n    pub agents: Vec<AgentStats>,\n    pub total_conversations: usize,\n    pub total_messages: usize,\n    pub time_range: Option<(DateTime<Utc>, DateTime<Utc>)>,\n}\n\nimpl ContentStats {\n    /// Query the database for current statistics\n    pub fn from_database(db: &Database) -> Result<Self, Error> {\n        // Fast aggregate queries\n        let agents = db.query_all(\"\n            SELECT agent, COUNT(*) as conv_count,\n                   SUM(message_count) as msg_count\n            FROM conversations\n            GROUP BY agent\n            ORDER BY conv_count DESC\n        \")?;\n\n        // ... build stats\n    }\n\n    /// Format for multi-select display\n    pub fn agent_choices(&self) -> Vec<String> {\n        self.agents.iter().map(|a| {\n            format!(\"{} ({} conversations)\", a.name, a.count)\n        }).collect()\n    }\n}\n```\n\n#### Progress Display (matching bv's style)\n\n```rust\n/// Multi-step progress display\npub fn create_export_progress() -> MultiProgress {\n    let mp = MultiProgress::new();\n\n    let style = ProgressStyle::default_bar()\n        .template(\"{prefix:.bold.dim} {bar:40.cyan/blue} {pos}/{len} {msg}\")\n        .unwrap()\n        .progress_chars(\"█▓░\");\n\n    // Create progress bars for each phase\n    let pb_filter = mp.add(ProgressBar::new(100));\n    pb_filter.set_prefix(\"Filtering\");\n    pb_filter.set_style(style.clone());\n\n    let pb_index = mp.add(ProgressBar::new(100));\n    pb_index.set_prefix(\"Indexing\");\n    pb_index.set_style(style.clone());\n\n    // ... more progress bars\n\n    mp\n}\n```\n\n#### Prerequisite Checking (from bv)\n\nbv performs prerequisite checks before proceeding.

\"running\" matches \"run\", \"runs\", \"runner\"\n-- - Good for: English prose, documentation, explanations\n-- NOTE: Use ONE tokenizer per FTS table (not both porter AND unicode61)\nCREATE VIRTUAL TABLE messages_fts USING fts5(\n    content,\n    content='messages',\n    content_rowid='id',\n    tokenize='porter'\n);\n\n-- FTS5 Index #2: Code/Path Search (unicode61 tokenchars)\n-- - Preserves snake_case, camelCase, file.extensions as searchable tokens\n-- - \"my_function\" is a single token (not split on underscore)\n-- - \"AuthController.ts\" matches exact filename\n-- - Good for: function names, paths, identifiers, error messages\nCREATE VIRTUAL TABLE messages_code_fts USING fts5(\n    content,\n    content='messages',\n    content_rowid='id',\n    tokenize=\"unicode61 tokenchars '_./\\\\'\"\n);\n\n-- OPTIONAL: FTS5 Trigram Index for LIKE-style substring matching\n-- Uncomment if users need arbitrary substring search (e.g., \"foo\" matches \"foobar\")\n-- Note: Significantly increases index size (~3x content size)\n-- CREATE VIRTUAL TABLE messages_trigram USING fts5(\n--     content,\n--     content='messages',\n--     content_rowid='id',\n--     tokenize='trigram'\n-- );\n\n-- NOTE: Triggers are NOT needed for static export databases.\n-- FTS5 content tables are populated via INSERT during export.\n-- The exported database is read-only in the browser.\n-- These triggers would only be needed if the database were modified client-side.\n\n-- ═══════════════════════════════════════════════════════════════════════════\n\n-- Indexes for common query patterns\nCREATE INDEX idx_messages_conversation ON messages(conversation_id);\nCREATE INDEX idx_messages_role ON messages(role);\nCREATE INDEX idx_conversations_agent ON conversations(agent);\nCREATE INDEX idx_conversations_workspace ON conversations(workspace);\nCREATE INDEX idx_conversations_started ON conversations(started_at);\n\n-- Metadata\nCREATE TABLE export_meta (\n    key TEXT PRIMARY KEY,\n    value TEXT\n);\n\nINSERT INTO export_meta (key, value) VALUES\n    ('schema_version', '1'),\n    ('exported_at', datetime('now')),\n    ('cass_version', '0.1.48'),\n    ('agents', '[\"claude-code\",\"codex\",\"gemini\"]'),\n    ('time_range', '{\"from\":null,\"to\":null}'),\n    ('encryption', 'aes-256-gcm'),\n    ('kdf', 'argon2id');\n```\n\n#### FTS5 Query Escaping\n\nFTS5 has special characters that must be escaped to prevent syntax errors or injection:\n\n```javascript\n// Escape special FTS5 characters for safe queries\nfunction escapeFts5Query(query) {\n    // FTS5 special chars: \" * ^ - : ( ) AND OR NOT NEAR\n    // For simple search: wrap each term in double-quotes\n    return query\n        .split(/\\s+/)\n        .filter(term => term.length > 0)\n        .map(term => {\n            // Escape embedded double-quotes by doubling them\n            const escaped = term.replace(/\"/g, '\"\"');\n            return `\"${escaped}\"`;\n        })\n        .join(' ');\n}\n\n// For prefix search (e.g., autocomplete), append *\nfunction escapeFts5Prefix(query) {\n    const terms = query.split(/\\s+/).filter(t => t.length > 0);\n    if (terms.length === 0) return '';\n    const lastTerm = terms.pop();\n    const escaped = terms.map(t => `\"${t.replace(/\"/g, '\"\"')}\"`);\n    escaped.push(`\"${lastTerm.replace(/\"/g, '\"\"')}\"*`);\n    return escaped.join(' ');\n}\n```\n\n#### Choosing Which FTS to Query\n\n```javascript\n// In viewer.js - route queries to appropriate FTS\nfunction searchMessages(rawQuery, searchMode = 'auto') {\n    // Auto-detect: if query looks like code (has underscores, dots, camelCase)\n    const isCodeQuery = /[_.]|[a-z][A-Z]/.test(rawQuery);\n\n    // CRITICAL: Escape the query to prevent FTS5 syntax errors\n    const query = escapeFts5Query(rawQuery);\n\n    // Use snippet() for query-aware context extraction (FTS5 built-in)\n    // snippet(table, column_idx, open_tag, close_tag, ellipsis, max_tokens)\n    if (searchMode === 'code' || (searchMode === 'auto' && isCodeQuery)) {\n        return db.exec(`\n            SELECT m.*,\n                   bm25(messages_code_fts) AS score,\n                   snippet(messages_code_fts, 0, '<mark>', '</mark>', '…', 64) AS snippet\n            FROM messages_code_fts\n            JOIN messages m ON messages_code_fts.rowid = m.id\n            WHERE messages_code_fts MATCH ?\n            ORDER BY score\n            LIMIT 100\n        `, [query]);\n    } else {\n        return db.exec(`\n            SELECT m.*,\n                   bm25(messages_fts) AS score,\n                   snippet(messages_fts, 0, '<mark>', '</mark>', '…', 64) AS snippet\n            FROM messages_fts\n            JOIN messages m ON messages_fts.rowid = m.id\n            WHERE messages_fts MATCH ?\n            ORDER BY score\n            LIMIT 100\n        `, [query]);\n    }\n}\n```\n\n### 9.2.1 Pre-Computed Data Files (Learned from bv)\n\nbv pre-computes expensive analytics server-side to avoid client-side computation. We adopt this pattern:\n\n```\ndata/\n├── statistics.json        # Pre-computed dashboard metrics\n├── agent_summary.json     # Per-agent statistics\n├── workspace_summary.json # Per-workspace breakdown\n├── timeline.json          # Message counts by day/week/month\n└── top_terms.json         # Most frequent search terms/topics\n```\n\n#### statistics.json\n\n```json\n{\n    \"total_conversations\": 2035,\n    \"total_messages\": 63701,\n    \"agents\": {\n        \"claude-code\": { \"conversations\": 1234, \"messages\": 45678 },\n        \"codex\": { \"conversations\": 567, \"messages\": 12345 },\n        \"gemini\": { \"conversations\": 234, \"messages\": 5678 }\n    },\n    \"time_range\": {\n        \"earliest\": \"2023-06-15T00:00:00Z\",\n        \"latest\": \"2025-01-06T23:59:59Z\"\n    },\n    \"message_roles\": {\n        \"user\": 31234,\n        \"assistant\": 32467\n    },\n    \"computed_at\": \"2025-01-06T12:34:56Z\"\n}\n```\n\n#### timeline.json (for sparkline charts)\n\n```json\n{\n    \"daily\": [\n        { \"date\": \"2025-01-01\", \"messages\": 156, \"conversations\": 12 },\n        { \"date\": \"2025-01-02\", \"messages\": 203, \"conversations\": 18 }\n    ],\n    \"weekly\": [...],\n    \"monthly\": [...]\n}\n```\n\n**Why pre-compute?**\n- Instant dashboard rendering (no SQL aggregation on load)\n- Reduces sql.js memory pressure\n- Enables rich visualizations without client computation\n- Pre-computed data is encrypted alongside the database\n\n### 9.2.2 Materialized Views for Search Performance\n\nFor large archives, create materialized views that accelerate common queries:\n\n```sql\n-- Materialized view: Recent conversations per agent\n-- NOTE: Window function results can't be used in WHERE of the same SELECT,\n-- so we use a subquery pattern.\nCREATE TABLE mv_recent_by_agent AS\nSELECT agent, conversation_id, title, started_at, message_count, rank\nFROM (\n    SELECT\n        agent,\n        id AS conversation_id,\n        title,\n        started_at,\n        message_count,\n        ROW_NUMBER() OVER (PARTITION BY agent ORDER BY started_at DESC) as rank\n    FROM conversations\n)\nWHERE rank <= 50;\n\nCREATE INDEX idx_mv_recent_agent ON mv_recent_by_agent(agent, rank);\n\n-- Materialized view: Search result snippets\n-- Pre-extract the first 200 chars of each message for fast preview\nCREATE TABLE mv_message_snippets AS\nSELECT\n    id,\n    conversation_id,\n    role,\n    SUBSTR(content, 1, 200) AS snippet,\n    LENGTH(content) AS full_length\nFROM messages;\n\nCREATE INDEX idx_mv_snippets_conv ON mv_message_snippets(conversation_id);\n```\n\n**Trade-off**: Increases database size by ~10-15% but dramatically improves search result rendering speed.\n\n### 9.3 Encryption Implementation (Envelope Encryption, Key Slots, Chunked AEAD)\n\n#### CLI Encryption Pipeline MUST be Streaming (Production Requirement)\n\nTo support archives approaching GitHub Pages limits without excessive memory usage, the CLI MUST\nstream: SQLite → compress → chunk → encrypt → write.\n\nKey properties:\n- O(1) memory with respect to archive size (bounded by a few buffers)\n- Chunks are boundaries in the *compressed stream* (decompress remains streaming in browser)\n- `config.json` is written last (after chunk_count is known)\n\n```rust\n// src/pages/encrypt.rs — streaming envelope encryption + chunked AEAD\nuse aes_gcm::{Aes256Gcm, Key, Nonce};\nuse aes_gcm::aead::{Aead, KeyInit, Payload};\nuse argon2::{Argon2, Params, Version};\nuse rand::RngCore;\nuse zeroize::Zeroize;\nuse std::io::{Read, Write};\n\n/// A single key slot (password or recovery secret)\npub struct KeySlot {\n    pub id: u32,\n    pub slot_type: String,    // \"password\" or \"recovery\"\n    pub kdf: String,          // \"argon2id\" or \"hkdf-sha256\"\n    pub kdf_params: Option<KdfParams>, // Only for argon2id\n    pub salt: [u8;

We adopt this:\n\n#### The Problem\n\nsql.js allocates memory in the WASM heap that JavaScript's garbage collector cannot see. Prepared statements, result sets, and intermediate data must be explicitly freed.\n\n#### The Solution: Scoped Resource Pattern\n\n```javascript\n/**\n * Execute a database operation with automatic resource cleanup.\n * Inspired by bv's withSubgraph() pattern.\n *\n * @param {SQL.Database} db - The sql.js database instance\n * @param {Function} operation - Function receiving (db) => result\n * @returns {any} - Result of the operation\n */\nfunction withDatabaseScope(db, operation) {\n    const statements = [];\n\n    // Proxy to track prepared statements\n    const trackedDb = {\n        prepare: (sql) => {\n            const stmt = db.prepare(sql);\n            statements.push(stmt);\n            return stmt;\n        },\n        exec: (sql) => db.exec(sql),\n        run: (sql, params) => db.run(sql, params),\n        // ... other methods pass through\n    };\n\n    try {\n        return operation(trackedDb);\n    } finally {\n        // Free all tracked statements\n        for (const stmt of statements) {\n            try { stmt.free(); } catch (e) { /* ignore */ }\n        }\n    }\n}\n\n// Usage example\nfunction searchMessages(db, query, limit = 50) {\n    return withDatabaseScope(db, (scopedDb) => {\n        const stmt = scopedDb.prepare(`\n            SELECT m.id, m.content, m.role, c.title, c.agent\n            FROM messages_fts\n            JOIN messages m ON messages_fts.rowid = m.id\n            JOIN conversations c ON m.conversation_id = c.id\n            WHERE messages_fts MATCH ?\n            ORDER BY rank\n            LIMIT ?\n        `);\n\n        stmt.bind([query, limit]);\n\n        const results = [];\n        while (stmt.step()) {\n            results.push(stmt.getAsObject());\n        }\n\n        return results;\n        // stmt.free() called automatically when scope exits\n    });\n}\n```\n\n#### Hybrid WASM Scorer Pattern (from bv)\n\nbv implements a hybrid approach where complex scoring runs in Rust/WASM for large datasets but falls back to JS for smaller ones:\n\n```javascript\n// Threshold for when WASM scoring provides benefit\nconst WASM_SCORER_THRESHOLD = 5000;\n\nasync function scoreResults(results, scorerWasm) {\n    if (results.length < WASM_SCORER_THRESHOLD) {\n        // JS scoring is faster for small datasets (no WASM call overhead)\n        return results.map(r => ({\n            ...r,\n            score: computeScoreJS(r)\n        }));\n    }\n\n    // For large datasets, WASM scoring is significantly faster\n    // Pack data into typed array for efficient WASM transfer\n    const packedData = packResultsForWasm(results);\n\n    // Call WASM scorer (compiled from Rust)\n    const scores = scorerWasm.score_batch(packedData);\n\n    // Unpack and merge\n    return results.map((r, i) => ({\n        ...r,\n        score: scores[i]\n    }));\n}\n\nfunction computeScoreJS(result) {\n    // Simple BM25-ish scoring in JS\n    const tf = result.matches / result.content_length;\n    const idf = Math.log(1 + result.total_docs / result.doc_freq);\n    return tf * idf;\n}\n```\n\n#### Memory Budget Monitoring\n\n```javascript\n// Monitor WASM memory usage\nfunction getWasmMemoryUsage() {\n    // sql.js exposes the underlying WASM module\n    if (window.SQL?.Module?.HEAPU8) {\n        const heap = window.SQL.Module.HEAPU8;\n        return {\n            used: heap.length,\n            limit: 256 * 1024 * 1024, // Typical browser limit\n            percentage: (heap.length / (256 * 1024 * 1024)) * 100\n        };\n    }\n    return null;\n}\n\n// Warn if approaching memory limit\nfunction checkMemoryPressure() {\n    const usage = getWasmMemoryUsage();\n    if (usage && usage.percentage > 80) {\n        console.warn(`WASM memory at ${usage.percentage.toFixed(1)}% - consider reducing result limits`);\n        return true;\n    }\n    return false;\n}\n```\n\n### 9.7 Viewer Scaling: Virtualization & Deep Links\n\nFor archives with 100K+ messages, the viewer must efficiently render large result sets and support direct linking to specific content.\n\n#### Virtual Scrolling for Large Result Sets\n\n```javascript\n// Use a virtual list for search results (only render visible items)\nimport { VirtualList } from './virtual-list.js';\n\nconst ITEM_HEIGHT = 80; // px per search result row\nconst BUFFER_ITEMS = 5; // extra items above/below viewport\n\nclass VirtualSearchResults {\n    constructor(container) {\n        this.container = container;\n        this.allResults = [];\n        this.virtualList = new VirtualList({\n            container,\n            itemHeight: ITEM_HEIGHT,\n            buffer: BUFFER_ITEMS,\n            renderItem: (item, index) => this.renderResultRow(item, index)\n        });\n    }\n\n    setResults(results) {\n        this.allResults = results;\n        this.virtualList.setItems(results);\n    }\n\n    renderResultRow(result, index) {\n        // Only called for visible items\n        return `\n            <div class=\"result-row\" data-id=\"${result.id}\">\n                <div class=\"result-title\">${escapeHtml(result.title)}</div>\n                <div class=\"result-meta\">${result.agent} • ${formatDate(result.created_at)}</div>\n                <div class=\"result-snippet\">${highlightMatches(result.snippet)}</div>\n            </div>\n        `;\n    }\n}\n```\n\n#### Deep Links with Hash-Based Routing\n\nSupport direct links to specific conversations and messages:\n\n```\nhttps://user.github.io/archive/#/c/12345          → conversation 12345\nhttps://user.github.io/archive/#/c/12345/m/67    → message 67 in conversation 12345\nhttps://user.github.io/archive/#/search/auth+bug → search for \"auth bug\"\n```\n\n```javascript\n// Hash-based router (works without server-side config)\nclass ArchiveRouter {\n    constructor(app) {\n        this.app = app;\n        window.addEventListener('hashchange', () => this.route());\n        this.route(); // Handle initial load\n    }\n\n    route() {\n        const hash = window.location.hash.slice(1); // Remove leading #\n        const parts = hash.split('/').filter(Boolean);\n\n        if (parts[0] === 'c' && parts[1]) {\n            const convId = parseInt(parts[1], 10);\n            const msgId = parts[2] === 'm' ? parseInt(parts[3], 10) : null;\n            this.app.openConversation(convId, msgId);\n        } else if (parts[0] === 'search' && parts[1]) {\n            const query = decodeURIComponent(parts[1]);\n            this.app.search(query);\n        } else {\n            this.app.showHome();\n        }\n    }\n\n    navigate(path) {\n        window.location.hash = path;\n    }\n}\n\n// Generate shareable links\nfunction getShareLink(conversationId, messageId = null) {\n    const base = window.location.href.split('#')[0];\n    const path = messageId\n        ? `/c/${conversationId}/m/${messageId}`\n        : `/c/${conversationId}`;\n    return `${base}#${path}`;\n}\n```\n\n#### Lazy Conversation Loading\n\nDon't load full conversation content until needed:\n\n```javascript\n// Conversation list shows only metadata (fast)\nasync function loadConversationList() {\n    return db.exec(`\n        SELECT id, title, agent, started_at, message_count\n        FROM conversations\n        ORDER BY started_at DESC\n        LIMIT 1000\n    `);\n}\n\n// Full messages loaded only when viewing (on-demand)\nasync function loadConversationMessages(convId) {\n    return db.exec(`\n        SELECT id, role, content, created_at\n        FROM messages\n        WHERE conversation_id = ?\n        ORDER BY idx ASC\n    `, [convId]);\n}\n```\n\n---\n\n## 10.

Frontend Technology Stack\n\n### Required Libraries (Updated for Chunked AEAD Architecture)\n\n| Library | Version | Uncompressed | Gzipped | Purpose |\n|---------|---------|--------------|---------|---------|\n| **sqlite-wasm** | 3.46+ | 850KB | 340KB | SQLite in browser (OPFS VFS, FTS5) — **ONLY RUNTIME** |\n| **fflate** | 0.8+ | 29KB | 9KB | Streaming deflate decompression |\n| **argon2-browser** | 1.18+ | 200KB | 78KB | Password hashing (WASM) |\n| **UI layer** | (custom) | ~10–30KB | ~4–12KB | CSP-safe UI (no eval; ES modules; no inline handlers) |\n| **Tailwind CSS** | 3.4+ | 398KB (full) | 50KB (JIT purged) | Utility-first CSS |\n| **Marked.js** | 14.0+ | 48KB | 18KB | Markdown rendering |\n| **Prism.js** | 1.29+ | 30KB | 11KB | Syntax highlighting |\n| **DOMPurify** | 3.1+ | 20KB | 8KB | XSS sanitization |\n| **html5-qrcode** | 2.3+ | 156KB | 52KB | QR code scanning |\n\n**SQLite Runtime Selection:**\n- **sqlite-wasm** is the only runtime (sql.js removed to eliminate duplicate APIs and bundle weight).\n- When OPFS is unavailable, use sqlite-wasm in-memory mode (deserialize DB bytes into the WASM heap).\n- This keeps the query API and memory model consistent across browsers.\n\n**Note:** Removing sql.js saves bundle size and eliminates a second DB API surface.\n\n### Optional Libraries (Feature-Dependent)\n\n| Library | Version | Size | When Needed |\n|---------|---------|------|-------------|\n| **D3.js** | 7.9+ | 273KB (87KB gz) | For timeline/chart visualizations |\n| **Force-Graph** | 1.43+ | 194KB (58KB gz) | For conversation relationship graphs |\n| **Mermaid** | 10.9+ | 3.2MB (800KB gz) | For rendering diagrams in messages |\n\n**Recommendation**: Start with core libraries only. Add D3/Force-Graph/Mermaid as opt-in features.\n\n### Total Bundle Size Analysis\n\n| Component | Uncompressed | Gzipped | Brotli |\n|-----------|--------------|---------|--------|\n| **Core JavaScript** | ~400KB | ~120KB | ~95KB |\n| **sqlite-wasm** | 850KB | 340KB | 280KB |\n| **Argon2 WASM** | 200KB | 78KB | 62KB |\n| **fflate** | 29KB | 9KB | 7KB |\n| **Alpine.js** | 44KB | 16KB | 13KB |\n| **Tailwind CSS** | 50KB (purged) | 12KB | 10KB |\n| **Vendor libs** | ~150KB | ~55KB | ~45KB |\n| **Total (code only)** | **~1.7MB** | **~630KB** | **~512KB** |\n\n**Note:** sql.js (640KB/290KB) is bundled as fallback but only loaded when sqlite-wasm OPFS is unavailable.\n\n#### Size by User Journey\n\n| Moment | What Loads | Gzipped Size |\n|--------|------------|--------------|\n| **Initial page** | index.html, auth.js, styles.css, Alpine | ~40KB |\n| **Password entry** | Argon2 WASM (async) | +78KB |\n| **After unlock** | sqlite-wasm, fflate, viewer.js, Marked, Prism | +460KB |\n| **Encrypted data** | payload.*.bin chunks (varies) | Variable |\n\n### Bundle Optimization Strategies (from bv)\n\n#### 1. Code Splitting\n\n```javascript\n// Load heavy dependencies only when needed\nasync function loadSearchUI() {\n    const { SearchModule } = await import('./search.js');\n    const { marked } = await import('./vendor/marked.min.js');\n    const { Prism } = await import('./vendor/prism.min.js');\n    return new SearchModule(marked, Prism);\n}\n```\n\n#### 2. WASM Loading Strategy\n\n```javascript\n// Parallel WASM initialization\nconst [argon2Ready, sqlReady] = await Promise.all([\n    initArgon2(),  // Only needed for decryption\n    initSqlJs(),   // Only needed after decryption\n]);\n```\n\n#### 3. Critical CSS Inlining\n\n```html\n<!-- index.html - inline critical CSS for instant render -->\n<style>\n    /* Only auth page styles - 2KB */\n    .auth-container { /* ... */ }\n    .password-input { /* ... */ }\n    .unlock-button { /* ... */ }\n</style>\n<!-- Load full styles async -->\n<link rel=\"preload\" href=\"styles.css\" as=\"style\" onload=\"this.rel='stylesheet'\">\n```\n\n#### 4. Asset Preloading\n\n```html\n<!-- Preload critical resources -->\n<link rel=\"preload\" href=\"vendor/argon2-wasm.wasm\" as=\"fetch\" crossorigin>\n<link rel=\"preload\" href=\"vendor/sql-wasm.wasm\" as=\"fetch\" crossorigin>\n<link rel=\"preload\" href=\"encrypted.bin\" as=\"fetch\" crossorigin>\n```\n\n### Browser Compatibility\n\n| Browser | Min Version | WASM | OPFS | Service Worker | Notes |\n|---------|-------------|------|------|----------------|-------|\n| Chrome | 102+ | ✅ | ✅ | ✅ | Full support |\n| Firefox | 111+ | ✅ | ✅ | ✅ | Full support |\n| Safari | 15.2+ | ✅ | ⚠️ | ✅ | OPFS limited |\n| Edge | 102+ | ✅ | ✅ | ✅ | Chromium-based |\n| Mobile Chrome | 102+ | ✅ | ✅ | ✅ | Android |\n| Mobile Safari | 15.2+ | ✅ | ⚠️ | ✅ | iOS, OPFS limited |\n\n**Hard Requirements**:\n- WebAssembly with `wasm-unsafe-eval` CSP support\n- Web Crypto API (SubtleCrypto)\n- ES2020+ JavaScript (async/await, optional chaining)\n- Fetch API with streaming support\n- CSS Grid/Flexbox\n\n**Soft Requirements** (graceful degradation):\n- OPFS (fallback: memory-only)\n- Service Workers (fallback: no offline)\n- SharedArrayBuffer (fallback: single-threaded Argon2)\n\n---\n\n## 12.

Implementation Phases\n\n### Phase 1: Core Export (2-3 weeks)\n\n- [ ] Database export with filters (agents, time, workspaces)\n- [ ] SQLite schema for web consumption\n- [ ] FTS5 index generation\n- [ ] Basic CLI interface (`cass pages --export-only`)\n\n### Phase 2: Encryption (1-2 weeks)\n\n- [ ] Argon2id key derivation\n- [ ] AES-256-GCM encryption\n- [ ] QR code generation\n- [ ] Password strength validation\n\n### Phase 3: Web Viewer (2-3 weeks)\n\n- [ ] Authentication UI (password + QR)\n- [ ] Decryption module (Argon2 WASM + Web Crypto)\n- [ ] sql.js integration\n- [ ] Search UI\n- [ ] Conversation viewer\n\n### Phase 4: Wizard & Deployment (1-2 weeks)\n\n- [ ] Interactive wizard (TUI-based)\n- [ ] GitHub Pages deployment\n- [ ] Cloudflare Pages deployment\n- [ ] Local preview server\n\n### Phase 5: Polish & Safety (1 week)\n\n- [ ] Secret detection\n- [ ] Pre-publish summary\n- [ ] Safety confirmations\n- [ ] Documentation\n\n### Phase 6: Testing & Hardening (1-2 weeks)\n\n- [ ] Cross-browser testing (Chrome, Firefox, Safari, Edge, mobile)\n- [ ] Performance optimization (large archive profiling)\n- [ ] Security audit (focus on crypto, CSP, input validation)\n- [ ] Edge case handling\n\n#### Crypto Test Vectors & Fuzzing\n\n**Test Vectors (known-answer tests):**\n- [ ] Argon2id: Verify against RFC 9106 test vectors\n- [ ] AES-256-GCM: Verify against NIST SP 800-38D test vectors\n- [ ] Key slot unwrapping: Round-trip encrypt/decrypt with multiple slots\n- [ ] Chunked AEAD: Verify chunk boundary handling, nonce derivation\n- [ ] AAD binding: Verify rejection when export_id or chunk_index tampered\n\n**Fuzzing targets:**\n- [ ] FTS5 query parser (malformed inputs, injection attempts)\n- [ ] Password input (Unicode normalization, empty, very long)\n- [ ] config.json parser (malformed JSON, missing fields, extra fields)\n- [ ] Chunk file fetch (partial responses, corrupted auth tags)\n- [ ] fflate decompressor (truncated streams, invalid deflate)\n\n**Integration tests:**\n- [ ] Full export → deploy → unlock cycle with test fixtures\n- [ ] Key add/revoke/rotate operations with verification\n- [ ] OPFS opt-in/clear-cache flow\n- [ ] Graceful degradation when sqlite-wasm unavailable (sql.js fallback)\n\n**Estimated Total: 9-14 weeks**\n\n---\n\n## 18. Open Questions\n\n### Design Decisions Needed\n\n1. **Session persistence**: Should decryption key be kept in sessionStorage (survives refresh) or memory only (maximum security)?\n\n2. **Multiple passwords**: Should we support multiple passwords with different access levels (e.g., \"viewer\" vs \"admin\")?\n\n3. **Expiring links**: Should we support time-limited access (e.g., \"this link expires in 30 days\")?\n\n4. **Offline mode**: After initial decryption, should the viewer work offline? (Service Worker caching)\n\n5. **Search index encryption**: Should we pre-build an encrypted search index, or build it client-side after decryption?\n\n6. **Mobile optimization**: Should we have a separate mobile-optimized viewer, or responsive design only?\n\n7. **Partial decryption**: Should we support decrypting individual conversations (granular encryption)?\n\n8. **Key rotation**: Should we support changing the password without re-exporting?\n\n### Technical Decisions Needed\n\n1. **Argon2 WASM library**: Use `argon2-browser` (established) or `argon2-wasm` (lighter)?\n\n2. **Chunking strategy**: Fixed-size chunks or semantic chunking (per-conversation)?\n\n3. **Compression**: Compress before encryption (saves space) or not (simpler)?\n\n4. **Asset embedding**: Embed all assets in Rust binary or keep separate for easier updates?\n\n---\n\n## 19. Appendix: Original Requirements\n\nThe following is the original prompt that initiated this proposal:\n\n> Carefully study the /data/projects/beads_viewer (also known as \"bv\") repo as it pertains to the web export feature that lets you make a version of the system that can go on gh pages as a static website. We would like to do something like that for cass, but with some major changes:\n>\n> * It needs to be very quick and easy to interactively (or via the command line using a robot mode input) to select which of the available indexed agents to include (default is ALL agents); the time range (default is ALL logs); which project folders you want to include (default is ALL).\n>\n> * Because these logs can easily include secret information you wouldn't want to release publicly on a public gh pages site (and because gh pages ONLY works with public repos), we need to have a rock solid encryption system that uses a password or qr code via webcam to unlock to allow the user in the web browser to view and search and see ANYTHING about the exported indexes. The public link to the static site on gh pages should go to an authentication page first, and the user must enter the right password or use the qr code; if they do, it would decrypt the contents and show the static web app; otherwise it wouldn't work at all and would reveal nothing.\n>\n> * Aside from that, we'd want to use a very similar stack, with sqlite.js (wasm) and other similar libraries and techniques that allow us to compile a modular, complex web app into a few files that \"just work\" in a secure, performant, way on gh pages with a stunning UI/UX. And also a very similar workflow in terms of the `bv -pages` wizard, with the same conveniences and details/polish, but with the difference that it has more emphasis of security and making it hard to accidentally publish to gh pages something without a password set (this should be possible but it should require the user to literally type: \"I UNDERSTAND AND ACCEPT THE RISKS\" to proceed with the final publishing step; we want to help users avoid shooting themselves in the foot. We should also, just prior to publishing, show the user the full list of coding agents, project folders, and time period included in the exported sqlite db file so there are no surprises!)\n\n---\n\n## Document History\n\n| Version | Date | Author | Changes |\n|---------|------|--------|---------|\n| 1.0 | 2026-01-06 | Claude (Opus 4.5) | Initial proposal |\n| 1.1 | 2026-01-06 | Claude (Opus 4.5) | Enhanced with bv deep dive insights (see below) |\n| 1.2 | 2026-01-06 | Claude (Opus 4.5) | Added envelope encryption, key slots, AAD binding |\n| 1.3 | 2026-01-06 | Claude (Opus 4.5) | Added chunked AEAD, worker architecture, redaction |\n| 1.4 | 2026-01-06 | Claude (Opus 4.5) | Production hardening (see below) |\n\n### Version 1.4 Changes (Production Hardening)\n\nThis version applies 12 revisions focused on internal consistency and production-grade implementation:\n\n1. **Crypto code consistency**: Sections 9.3, 9.4 now fully implement envelope encryption design from §7.2\n2. **Streamable chunked AEAD**: Section 9.5 rewritten for streaming decrypt + decompress pipeline\n3. **AAD binding**: export_id used as Additional Authenticated Data throughout to prevent chunk swapping\n4. **Streaming decompression**: Added fflate library (~9KB gzipped) to Section 11\n5. **SQLite runtime**: Clarified sqlite-wasm as primary (OPFS support), sql.js as fallback\n6. **Worker architecture**: All crypto/decompress/DB operations in dedicated Web Worker\n7. **OPFS opt-in**: Default is memory-only; \"Remember on this device\" checkbox enables persistence\n8. **Redaction pipeline**: Added FR-6 with secret detection, user-defined rules, share profiles\n9. **Key management CLI**: Added `cass pages key {list,add,revoke,rotate}` commands\n10. **SQL bug fixes**: Fixed invalid materialized view (window function in WHERE), added FTS5 query escaping\n11. **GitHub Pages limits**: Clarified sites are ALWAYS public, added real size limits (1GB site, 100MiB/file)\n12. **Test hardening**: Phase 6 now includes crypto test vectors, fuzzing targets, integration tests\n\n### Version 1.1 Changes (bv Deep Dive Enhancements)\n\nBased on a comprehensive analysis of bv's (beads_viewer) web export implementation, the following enhancements were added:\n\n#### New Sections Added:\n- **Section 7.5**: Content Security Policy (CSP) with strict headers and `wasm-unsafe-eval`\n- **Section 7.6**: Service Worker for CORS isolation\n- **Section 9.2.1**: Pre-computed data files pattern (statistics.json, timeline.json)\n- **Section 9.2.2**: Materialized views for search performance\n- **Section 9.5**: Multi-tier database loading (OPFS caching, chunked downloads, SHA256 verification)\n- **Section 9.6**: WASM memory management (scoped resource pattern, hybrid scorer)\n- **Section 8.1.1**: Wizard implementation details (state machine, prerequisites, progress display)\n\n#### Enhanced Existing Sections:\n- **Section 9.2**: FTS5 now uses `porter unicode61` tokenizer for better search\n- **Section 9.2**: Added indexes for common query patterns\n- **Section 11**: Updated library versions with accurate sizes (gzipped and Brotli)\n- **Section 11**: Added optional libraries (D3, Force-Graph, Mermaid)\n- **Section 11**: Added bundle optimization strategies (code splitting, WASM loading, preloading)\n- **Section 11**: Enhanced browser compatibility table with OPFS/SW columns\n\n#### Key Technical Insights Incorporated:\n1. **OPFS caching** survives page refreshes, providing instant database loading on return visits\n2. **Database chunking** for files >5MB with 1MB chunks and SHA256 verification per chunk\n3. **Multi-tier loading strategy** (OPFS cache → chunked → single file)\n4. **FTS5 with Porter stemmer** matches word variants (\"running\" → \"run\")\n5. **withDatabaseScope()** pattern for WASM memory management\n6. **Hybrid WASM scorer** falls back to JS for small datasets (<5000 items)\n7. **Pre-computed analytics** (statistics.json, timeline.json) for instant dashboard rendering\n8. **CSP with wasm-unsafe-eval** required for sql.js and Argon2 WASM\n9. **Service Worker** for additional CORS isolation and offline capabilities\n10. **Prerequisite checking** before deployment (gh CLI, authentication, disk space)\n\n---\n\n*End of Proposal Document*\n"

Goals & Non‑Goals\n\n### 1.1 Goals\n\n* **Speed**\n\n  * “Perceived instant” search as you type (<50–80ms for moderate corpora; <200ms for huge ones)\n  * Initial indexing amortized via background jobs + incremental updates\n* **Coverage**\n\n  * First-class support for:\n\n    * OpenAI **Codex CLI** (terminal agent)([GitHub][3])\n    * **Claude Code** (CLI & VS Code extension)([GitHub][4])\n    * **Google Gemini CLI** (`gemini-cli`)([GitHub][5])\n    * **Amp Code** (Sourcegraph’s Amp CLI)([Amp Code][6])\n    * **Cline** (VS Code extension)([Reddit][7])\n    * **OpenCode** (opencode-ai/opencode CLI)([HackMD][8])\n  * Pluggable architecture to add Cursor CLI, Roo Code, etc. later.\n* **UX**\n\n  * Beautiful TUI (ratatui widgets, color themes per agent)([GitHub][9])\n  * Hotkeys to filter by time, agent, workspace, project; view full transcript; jump to original log.\n* **Portability**\n\n  * Single static(ish) binary per OS; zero runtime deps except libc.\n  * Works on:\n\n    * Linux (x86_64, aarch64)\n    * macOS (arm64, x86_64)\n    * Windows (x86_64, possibly via WSL if some agents are Linux-only).\n\n### 1.2 Non‑Goals / Constraints\n\n* No network calls to remote agent backends (Amp/Claude/Codex clouds). Only **local artifacts** (JSON/JSONL/SQLite) to avoid any auth/privacy issues.\n* We don’t attempt to *write back* to these tools’ histories; we only **read and index**.\n* Not a general “code search” tool; scope is **chat / agent transcript search**.\n\n---\n\n## 0. LLM-first CLI spec (2025-11)\n\nContext: zero legacy users. Optimize `cass` for AI/automation (tmux/headless), not for human muscle memory. Defaults can change freely.\n\n### Contracts\n* CLI is primary; TUI only on explicit `cass tui` (never auto when automation flags present or stdout non-TTY without `tui`).\n* Stdout is data-only; stderr is diagnostics/progress.\n* Machine error schema: `{\"error\":{\"code\":int,\"kind\":string,\"message\":string,\"hint\":string,\"retryable\":bool}}`.\n* Exit codes: 0 ok; 2 usage; 3 missing index/db; 4 network; 5 data-corrupt; 6 incompatible-version; 7 lock/busy; 8 partial; 9 unknown.\n* Deterministic defaults printed in help (data dir, db path, log path). Color bars off when non-TTY unless forced.\n\n### Global flags / subcommands\n* `--robot-help`: deterministic, wide guide (Summary, Commands, Defaults, Exit codes, JSON/Error schema, Examples, Env, Paths, Trace, Contracts); version header (crate + contract version). No ANSI unless `--color=always`.\n* `robot-docs <topic>` topics: `commands`, `env`, `paths`, `schemas`, `exit-codes`, `examples`, `contracts`, `wrap`.\n* `--json` everywhere data flows (search/index/etc.).\n* `--color=auto|never|always`; default auto (off when non-TTY).\n* `--progress=plain|bars|none`; default bars on TTY, plain otherwise.\n* `--wrap <cols>` and `--nowrap`; default: no forced wrap (wide output encouraged).\n* `--trace-file <path>`: JSONL spans {start_ts,end_ts,duration_ms,cmd,args,exit_code,error?}; never to stdout/stderr.\n\n### Behavioral rules\n* If automation flag present (`--json`, `--robot-help`, `robot-docs`, `--trace-file`), TUI path is bypassed; main returns after CLI action.\n* If no subcommand and stdout non-TTY: emit short guidance and exit 2 (don’t launch TUI).\n* Search pagination: `--limit`, `--offset`, stable ordering.\n* Progress bars suppressed by `--quiet` or `--progress=none`; data unaffected.\n\n### Documentation targets\n* Embed robot-help content generator; robot-docs topic renders parse-stable blocks.\n* README “AI automation” section with wide examples, wrap guidance, trace usage, automation defaults, and no-legacy stance.\n* Changelog + version bump; header in robot-help mirrors crate + contract versions.\n\n### Testing targets\n* Snapshots for `--robot-help` and each `robot-docs` topic.\n* Contract tests: exit codes per scenario, JSON validity, color suppression when non-TTY, wrap flags, TUI bypass, trace file writing.\n* Perf sanity: ensure minimal startup overhead for robot-help/doc paths.\n\n---\n\n## 2. Research Summary: Where Each Tool Stores History\n\nThis section turns web research into concrete connector requirements.\n\n### 2.1 OpenAI Codex CLI\n\n* **What it is**\n  Open-source terminal-native coding agent (`codex` CLI) that reads/edits/runs code locally.([GitHub][3])\n\n* **Config & state locations**\n\n  * Config: `~/.codex/config.toml` (or `$CODEX_HOME/config.toml`)([GitHub][3])\n  * Session logs:\n\n    * JSONL “rollout” logs under\n      `~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl` (or `$CODEX_HOME/sessions/...`)([GitHub][10])\n    * Optionally a consolidated `history.jsonl` in `$CODEX_HOME/history.jsonl` controlled by `history.*` config (e.g. `history.persistence`, `history.max_bytes`).([GitHub][11])\n\n* **Implications for us**\n\n  * Canonical source = **rollout JSONL** files; each describes a session with:\n\n    * Metadata (session id, start time, working directory)\n    * User messages / agent steps / approvals / tool runs.\n  * We must:\n\n    * Discover `$CODEX_HOME` (env or default `~/.codex`)\n    * Recursively scan `sessions/*/*` for `rollout-*.jsonl`.\n    * Parse each JSONL line as a “log event” and reconstruct conversations.\n\n### 2.2 Claude Code (CLI + VS Code extension)\n\n* **What it is**\n  Anthropic’s agentic coding tool (“Claude Code”) for terminal + editor.\n\n* **History locations (based on ecosystem tools & docs)**\n  Community tools for Claude Code history refer to:\n\n  * JSONL session logs under `~/.claude/projects/<project-id>/...`([GitHub][4])\n  * Per-project `.claude` / `.claude.json` files in repos for configuration and sometimes embedded logs.([GitHub][12])\n\n* **CLI logs**\n\n  * Several open-source viewers take Claude Code *CLI* logs (JSONL) and render them as Markdown, implying:\n\n    * CLI writes JSONL logs; path varies but `~/.claude/projects` is a strong default.([claude-hub.com][13])\n\n* **Implications**\n\n  * We need a **Claude connector** that:\n\n    * Scans `~/.claude/projects/**` for JSONL files (exclude non-log files).\n    * Optionally scans each repo’s `.claude` or `.claude.json` for embedded transcript data.\n    * Parses JSONL events into our unified schema.\n\n### 2.3 Gemini CLI (`gemini-cli`)\n\n* **What it is**\n  Official Google Gemini CLI for terminal-based workflows.([GitHub][14])\n\n* **History location**\n\n  * A popular “Gemini CLI logs prettifier” script explicitly states:\n    **“The Gemini CLI stores chat history and session checkpoints in a series of JSON files located in `~/.gemini/tmp`.”**([GitHub][5])\n  * Structure:\n\n    * `~/.gemini/tmp/<project-hash>/checkpoint-*.json`, `chat-log-*.json`, etc.([GitHub][5])\n\n* **Implications**\n\n  * Connector should:\n\n    * Enumerate `~/.gemini/tmp/*` directories.\n    * Treat each directory as a project/session cluster.\n    * Parse checkpoint & log JSON into conversation threads (ordered by timestamp / sequence).\n\n### 2.4 Amp Code (Sourcegraph Amp CLI)\n\n* **What it is**\n  “Frontier coding agent” available as VS Code extension and CLI, built by Sourcegraph.([Amp Code][6])\n\n* **Local storage**\n\n  * Amp mainly stores threads on Sourcegraph servers (Doc & community reports note that “all threads are stored on Sourcegraph servers”).([Reddit][15])\n  * VS Code extension:\n\n    * Caches thread history locally under VS Code’s `globalStorage` directory (extension-managed).([Amp Code][16])\n  * Amp CLI:\n\n    * Stores credentials in:\n\n      * Linux/macOS: `~/.local/share/amp/secrets.json`\n      * Windows: `%APPDATA%\\amp\\secrets.json`([Amp Code][16])\n    * Chat contents themselves are not guaranteed to be fully cached locally.\n\n* **Implications**\n\n  * Our **Amp connector** must:\n\n    * Respect that the **primary truth is remote**; we only index whatever is cached locally:\n\n      * VS Code globalStorage (same pattern as Cline / other extensions).\n      * Any CLI cache directories if they exist (we’ll detect by exploring `~/.local/share/amp/` for JSON/JSONL).\n    * Provide partial coverage; document clearly in the UI (e.g. label Amp as “local cache only”).\n\n### 2.5 Cline (VS Code task-based coding agent)\n\n* **What it is**\n  Popular VS Code extension & ecosystem fork (Roo Code).\n\n* **Local storage**\n\n  * Migration docs & issues consistently point to:\n\n    * macOS Cline data dir:\n      `~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev`([Reddit][7])\n    * Linux analog:\n      `~/.config/Code/User/globalStorage/saoudrizwan.claude-dev` (inferred from VS Code layout).\n    * Windows analog:\n      `%APPDATA%\\Code\\User\\globalStorage\\saoudrizwan.claude-dev` (same pattern).\n  * In that directory, users mention files like:\n\n    * `taskHistory.json` (index of tasks displayed in “Recent tasks”)\n    * One file per task containing:\n\n      * `task_metadata.json`\n      * `ui_messages.json`\n      * `api_conversation_history.json`([Stack Overflow][17])\n\n* **Implications**\n\n  * Cline connector must:\n\n    * Find the **VS Code globalStorage** dir for the Cline extension.\n    * Walk all task directories, reading:\n\n      * `task_metadata.json` → title, created_at, workspace, provider, etc.\n      * `ui_messages.json` / `api_conversation_history.json` → actual transcript.\n    * Rebuild conversation threads from these JSON files even if `taskHistory.json` is corrupted (StackOverflow questions show that this is needed).([Stack Overflow][17])\n\n### 2.6 OpenCode CLI (opencode-ai/opencode)\n\n* **What it is**\n  Local coding agent CLI with MCP support; uses SQLite to persist sessions.([GitHub][18])\n\n* **Storage**\n\n  * Quickstart notes and blog posts describe:\n\n    * On first run, OpenCode creates a `.opencode` **data directory** in the project root and initializes a **SQLite database** for conversation/sessions.([HackMD][8])\n    * Config includes a `data.directory` / `database_path` option; default often resides in:\n\n      * Project-local `.opencode`\n      * Or a global `~/.config/opencode/...` SQLite file (depending on config).([atalupadhyay][19])\n\n* **Implications**\n\n  * OpenCode connector:\n\n    * Locates per-project `.opencode` directories by scanning:\n\n      * Current git repos (via `git rev-parse --show-toplevel` or just walking up from CWD).\n      * `$HOME` for `.opencode` when not inside a repo (optional).\n    * Reads SQLite schema (already there), maps `sessions`, `messages`, etc. → our unified schema.\n\n### 2.7 Summary of Paths the App Must Know\n\nPer agent, we need a detection matrix (paths inferred by OS):\n\n| Agent       | Primary history roots (defaults)                                                                                                              |\n| ----------- | --------------------------------------------------------------------------------------------------------------------------------------------- |\n| Codex CLI   | `$CODEX_HOME/sessions/YYYY/MM/DD/rollout-*.jsonl` (default CODEX_HOME=`~/.codex`); plus `$CODEX_HOME/history.jsonl` if enabled.([GitHub][10]) |\n| Claude Code | `~/.claude/projects/**` JSONL logs; plus per-repo `.claude` / `.claude.json`.([GitHub][4])                                                    |\n| Gemini CLI  | `~/.gemini/tmp/<project-hash>/{chat,checkpoint}-*.json`.([GitHub][5])                                                                         |\n| Amp         | VS Code globalStorage cache for Amp;

Core Architecture\n\n### 3.1 Top-level Components\n\n1. **CLI / entrypoint** (`main.rs`)\n\n   * Subcommands:\n\n     * `agent-search tui` (default): launch full-screen TUI.\n     * `agent-search index`:\n\n       * `--full`: rebuild entire index from scratch.\n       * `--incremental`: only new or changed logs.\n     * `agent-search inspect <agent> <session-id>`: dump normalized view of a single conversation.\n\n2. **Connectors layer** (`connectors::*`)\n\n   * One module per agent:\n\n     * `connectors::codex`\n     * `connectors::claude_code`\n     * `connectors::gemini`\n     * `connectors::amp`\n     * `connectors::cline`\n     * `connectors::opencode`\n   * Each exposes:\n\n     * Detection:\n\n       ```rust\n       fn detect_installation(env: &Environment) -> DetectionResult;\n       ```\n     * Scan & normalize:\n\n       ```rust\n       fn scan_sessions(ctx: &ScanContext) -> anyhow::Result<Vec<NormalizedConversation>>;\n       fn watch_paths(ctx: &ScanContext, tx: Sender<IndexUpdate>) -> anyhow::Result<()>;\n       ```\n\n3. **Data model & persistence** (`model`, `storage`)\n\n   * `model` defines normalized Rust structs for:\n\n     * `Agent`, `Conversation`, `Message`, `Snippet`, `Workspace`.\n   * `storage::sqlite`\n\n     * SQLite DB (rusqlite) with strongly-typed schema.([Docs.rs][20])\n\n4. **Search engine** (`search`)\n\n   * Primary index: **Tantivy** (Lucene-like).([GitHub][1])\n   * Secondary / fallback: SQLite FTS5 virtual table.([SQLite][21])\n\n5. **TUI / UI** (`ui`)\n\n   * Built with Ratatui + `ratatui-crossterm` backend.([GitHub][9])\n\n6. **Index orchestrator** (`indexer`)\n\n   * Coordinates:\n\n     * Initial full scan\n     * Incremental updates (filesystem watchers via `notify`)([GitHub][22])\n     * Rebuilding indexes when schema changes.\n\n7. **Config** (`config`)\n\n   * YAML/TOML config stored in XDG / platform-appropriate directories via `directories` crate.([Crates][23])\n\n8. **Logging & error handling**\n\n   * `tracing` + `tracing-subscriber` for logging.\n   * `color-eyre` or `miette` for pretty diagnostics in CLI mode.([The Rust Programming Language Forum][24])\n\n### 3.2 Process Model & Threads\n\n* **UI thread**\n\n  * Runs the Ratatui event loop, processes user input (crossterm events).\n* **Search worker pool**\n\n  * Uses `rayon` to parallelize search + scoring over Tantivy index.([Crates][25])\n* **Index worker**\n\n  * Thread that:\n\n    * Listens for `IndexUpdate` messages from:\n\n      * Connectors (full/partial scans)\n      * Filesystem watchers (notify)\n    * Batch-writes to SQLite & Tantivy.\n\nCommunication via `crossbeam::channel`:\n\n```rust\nenum UiEvent { Key(KeyEvent), Tick, SearchResult(SearchResults) }\nenum IndexCommand { FullReindex, IncrementalScan, FilesystemEvent(FsEvent) }\n\nstruct Channels {\n    ui_tx: Sender<UiEvent>, ui_rx: Receiver<UiEvent>,\n    index_tx: Sender<IndexCommand>, index_rx: Receiver<IndexCommand>,\n}\n```\n\n---\n\n## 4. Unified Data Model & SQLite Schema\n\n### 4.1 Conceptual Model\n\n* **Agent**: `codex`, `claude_code`, `gemini_cli`, `amp`, `cline`, `opencode`, …\n* **Workspace**: root path of repo / project (if known).\n* **Conversation**: one “thread” or “task”.\n* **Message**: user or agent message, plus tool runs / actions.\n* **Snippet**: optional code snippet or file section references.\n\n### 4.2 SQLite Schema (normalized, tuned for performance)\n\nWe’ll create a single SQLite DB under app data dir:\n\n* Use `rusqlite` with `bundled` feature to ship our own SQLite build (ensures FTS5 is available across platforms).([Docs.rs][20])\n\n**Tables**\n\n```sql\n-- Agents (tools)\nCREATE TABLE agents (\n    id              INTEGER PRIMARY KEY,\n    slug            TEXT NOT NULL UNIQUE,   -- \"codex\", \"cline\", etc.\n    name            TEXT NOT NULL,\n    version         TEXT,\n    kind            TEXT NOT NULL,         -- \"cli\", \"vscode\", \"hybrid\"\n    created_at      INTEGER NOT NULL,\n    updated_at      INTEGER NOT NULL\n);\n\n-- Workspaces (projects / repos)\nCREATE TABLE workspaces (\n    id              INTEGER PRIMARY KEY,\n    path            TEXT NOT NULL,         -- canonical absolute path\n    display_name    TEXT,\n    UNIQUE(path)\n);\n\n-- Conversations (threads / tasks)\nCREATE TABLE conversations (\n    id              INTEGER PRIMARY KEY,\n    agent_id        INTEGER NOT NULL REFERENCES agents(id),\n    workspace_id    INTEGER REFERENCES workspaces(id),\n    external_id     TEXT,                  -- tool's session/task ID\n    title           TEXT,\n    source_path     TEXT NOT NULL,         -- original log / DB path\n    started_at      INTEGER,               -- unix millis\n    ended_at        INTEGER,\n    approx_tokens   INTEGER,\n    metadata_json   TEXT,                  -- extra tool-specific info\n    UNIQUE(agent_id, external_id)\n);\n\n-- Messages\nCREATE TABLE messages (\n    id              INTEGER PRIMARY KEY,\n    conversation_id INTEGER NOT NULL REFERENCES conversations(id) ON DELETE CASCADE,\n    idx             INTEGER NOT NULL,      -- order in conversation\n    role            TEXT NOT NULL,         -- \"user\",\"agent\",\"tool\",\"system\"\n    author          TEXT,\n    created_at      INTEGER,               -- may be null if unknown\n    content         TEXT NOT NULL,\n    extra_json      TEXT\n);\n\n-- Optional per-message code snippets / file refs\nCREATE TABLE snippets (\n    id              INTEGER PRIMARY KEY,\n    message_id      INTEGER NOT NULL REFERENCES messages(id) ON DELETE CASCADE,\n    file_path       TEXT,\n    start_line      INTEGER,\n    end_line        INTEGER,\n    language        TEXT,\n    snippet_text    TEXT\n);\n\n-- Simple tag layer (for later)\nCREATE TABLE tags (\n    id              INTEGER PRIMARY KEY,\n    name            TEXT NOT NULL UNIQUE\n);\n\nCREATE TABLE conversation_tags (\n    conversation_id INTEGER NOT NULL REFERENCES conversations(id) ON DELETE CASCADE,\n    tag_id          INTEGER NOT NULL REFERENCES tags(id) ON DELETE CASCADE,\n    PRIMARY KEY (conversation_id, tag_id)\n);\n```\n\n### 4.3 SQLite Performance Tuning\n\nOn DB open, apply pragmas:\n\n```sql\nPRAGMA journal_mode = WAL;\nPRAGMA synchronous = NORMAL;       -- or FULL for \"safe mode\"\nPRAGMA temp_store = MEMORY;\nPRAGMA cache_size = -65536;        -- 64MB in pages\nPRAGMA foreign_keys = ON;\nPRAGMA mmap_size = 268435456;      -- 256MB (tuneable)\n```\n\nIndexes:\n\n```sql\nCREATE INDEX idx_conversations_agent_started\n    ON conversations(agent_id, started_at DESC);\n\nCREATE INDEX idx_messages_conv_idx\n    ON messages(conversation_id, idx);\n\nCREATE INDEX idx_messages_created\n    ON messages(created_at);\n```\n\n### 4.4 SQLite FTS5 Mirror\n\nTo support fallback search (and some advanced filters), create an FTS5 virtual table:\n\n```sql\nCREATE VIRTUAL TABLE fts_messages\nUSING fts5(\n    content,\n    title,\n    agent_slug,\n    workspace,\n    message_id UNINDEXED,\n    conversation_id UNINDEXED,\n    created_at UNINDEXED,\n    tokenize = \"porter\"\n);\n```\n\nWe then keep `fts_messages` synchronized with `messages` via our Rust code (not triggers, to avoid performance surprises).\n\nFTS5 gives fast text search, built-in ranking, and helps on platforms where Tantivy or its index is temporarily unavailable.([SQLite][21])\n\n---\n\n## 5. Search Engine (Tantivy) Design\n\n### 5.1 Why Tantivy\n\n* Tantivy is a **Rust-native Lucene-like full-text search engine** with high performance and a feature set comparable to Elasticsearch’s core text features.([GitHub][1])\n* Well suited as “Rust equivalent to Lucene/Elastic” per the requirement.\n\n### 5.2 Index Layout\n\n**Index location**\n\n* On-disk under app data dir: `data_dir/index/` (per schema version, e.g. `index/v1/`).\n\n**Fields**\n\n* `message_id` (u64, stored)\n* `conversation_id` (u64, stored)\n* `agent_slug` (string, indexed, fast field for filters)\n* `workspace` (string, indexed)\n* `created_at` (i64, indexed as fast field, sortable)\n* `role` (string, indexed)\n* `title` (text, indexed & stored)\n* `content` (text, indexed & stored)\n\nUse:\n\n* `TEXT` fields with a standard analyzer (tokenization, lowercasing, stopwords).\n* `FAST` fields for `created_at` and `agent_slug` to support efficient range & term filters.\n\n### 5.3 Query Model\n\nWhen user types into search box:\n\n1. Build a Tantivy query:\n\n   * `Query::Boolean` combining:\n\n     * Full-text query on `content` & `title`\n\n       * Multi-field query parser with weights:\n\n         * `title` weight 3.0\n         * `content` weight 1.0\n     * Agent filter(s): `TermQuery` on `agent_slug`.\n     * Time filter: `RangeQuery` on `created_at`.\n2. Limit: top 100 hits (configurable).\n3. Group results by conversation for TUI display:\n\n   * Each conversation row shows best-scoring message snippet.\n\n### 5.4 Performance\n\n* Pre-open a Tantivy `IndexReader` & `Searcher` on startup.\n* Use Tantivy’s multi-threaded search (via its internal threadpool) plus `rayon` for grouping and post-processing.([quickwit.io][26])\n* Debounce keystroke-triggered searches by ~100–150ms:\n\n  * Send `SearchRequest { query, filters, timestamp }` on each change.\n  * Worker deduplicates by dropping stale requests.\n\n---\n\n## 6. TUI Design\n\n### 6.1 Libraries & Terminal Handling\n\n* TUI: `ratatui` for widgets/layout.([GitHub][9])\n* Backend: `ratatui-crossterm` using `crossterm` for cross-platform terminal control.([Crates][27])\n\n### 6.2 Layout\n\nMain screen = 3 panes:\n\n1. **Top bar** (1–2 rows)\n\n   * Search input `[ query here… ]`\n   * Filter summary:\n\n     * `Agents: Codex, Claude, Gemini`\n     * `Time: Last 7 days`\n     * `Workspace: all`\n   * Right side: status (indexing progress, #docs, backend used: Tantivy/FTS)\n\n2. **Left pane – Results list**\n\n   * Scrollable list of hit conversations/messages.\n   * Each row:\n\n     * `[AGENT ICON] [REL TIME] [WORKSPACE] Title / first line snippet`\n   * Colored by agent:\n\n     * Codex: cyan\n     * Claude: purple\n     * Gemini: blue\n     * Amp: magenta\n     * Cline: green\n     * OpenCode: yellow\n\n3. **Right pane – Detail**\n\n   * When a row is selected:\n\n     * Shows full conversation:\n\n       * Timestamped\n       * Roles (“You”, “Agent”, “Tool”) with colors.\n   * Tabs at top: `[Messages] [Code Snippets] [Raw JSON]`.\n\nBottom status line:\n\n* Hints: `Enter: open | /: search | f: filters | t: time | a: agents | w: workspace | ?: help | q: quit`.\n\n### 6.3 Hotkeys\n\n* Navigation:\n\n  * `↑/↓` or `k/j` – move selection in result list.\n  * `PgUp/PgDn` – page results.\n  * `Tab` – toggle focus between search box / results / detail.\n* Search:\n\n  * `/` – focus search input.\n  * `Esc` – clear search if input nonempty, else go back/focus results.\n* Filters:\n\n  * `f` – open filter popover.\n  * `a` – agent filter:\n\n    * Checkbox list of agents; space toggles; enter applies.\n  * `t` – time filter modal:\n\n    * Quick presets: `1` = last 24h, `7` = last 7 days, `3` = last 30 days, `0` = all.\n    * `c` = custom; prompts from/to dates.\n  * `w` – workspace filter:\n\n    * List of detected workspaces; search-as-you-type fuzzy filter (local to this list).\n* Detail:\n\n  * `Enter` – open conversation in detail pane (if not already).\n  * `o` – open underlying log/DB in external editor (`$EDITOR + path:line`).\n  * `r` – toggle between “grouped by turn” vs “flat log” view.\n\n### 6.4 Styling & Polish\n\n* Use Ratatui’s `Block`, `List`, `Paragraph`, `Tabs` widgets with:\n\n  * Light borders, rounded corners where available.\n  * Highlight style for selected row: reverse video + bold.\n  * Soft accent colors rather than neon; calibrate for readability in dark mode.\n* Support light/dark themes via config (`theme = \"dark\" | \"light\"`).\n* Optional “minimal mode” that disables some borders for simpler terminals.\n\n---\n\n## 7. Connectors: Detailed Behavior\n\n### 7.1 Shared Connector Abstractions\n\nDefine:\n\n```rust\nstruct NormalizedConversation {\n    agent_slug: String,\n    external_id: String,\n    title: Option<String>,\n    workspace: Option<PathBuf>,\n    source_path: PathBuf,\n    started_at: Option<i64>,\n    ended_at: Option<i64>,\n    metadata: serde_json::Value,\n    messages: Vec<NormalizedMessage>,\n}\n\nstruct NormalizedMessage {\n    role: MessageRole,\n    author: Option<String>,\n    created_at: Option<i64>,\n    content: String,\n    extra: serde_json::Value,\n    snippets: Vec<NormalizedSnippet>,\n}\n```\n\nEach connector:\n\n* Emits `NormalizedConversation` objects.\n* Does **idempotent** scans: uses `source_path` + `external_id` to avoid duplicates.\n\n### 7.2 Codex Connector\n\n**Detection**\n\n* Check:\n\n  * Is `codex` binary on PATH? Use `which` crate to detect executables robustly across platforms.([Stack Overflow][28])\n  * Or does `~/.codex` exist?\n\n**Scan**\n\n* Determine `$CODEX_HOME`:\n\n  * Env var `CODEX_HOME` or default `~/.codex`.\n* Enumerate `sessions`:\n\n  * `CODEX_HOME/sessions/*/*/rollout-*.jsonl`\n* For each `rollout-*.jsonl`:\n\n  * Treat file as one “session”.\n  * Parse JSONL line-by-line:\n\n    * Identify user messages vs agent messages (look at event type: `user_message`, `assistant_message`, etc.).\n    * Extract timestamps, workspace path, title (if present), approvals, tool runs.\n  * Build `NormalizedConversation`:\n\n    * `external_id` = file path or session UUID from JSON.\n    * `workspace` = working directory from session metadata.\n    * `started_at` = first event timestamp; `ended_at` = last.\n* Optionally, incorporate `history.jsonl`:\n\n  * As fallback when sessions missing; but primary will be session logs.\n\n**Incremental updates**\n\n* Use `notify` to watch:\n\n  * `$CODEX_HOME/sessions` directory for new/changed files.\n* On new `rollout-*.jsonl`:\n\n  * Parse, upsert in DB and update Tantivy/FTS.\n\n### 7.3 Claude Code Connector\n\n**Detection**\n\n* Heuristics:\n\n  * `~/.claude` directory exists.\n  * VS Code extension for Claude installed (look for `claude-code` or similar in `globalStorage` directories).\n* Config-driven override:\n\n  * Allow user to specify `claude.projects_dir` etc.\n\n**Scan**\n\n* Root: `~/.claude/projects`.\n* For each project dir:\n\n  * List `.jsonl` history logs (names may vary: `history-*.jsonl`, `session-*.jsonl`).\n  * Parse JSONL:\n\n    * Each line = event. Identify conversation boundaries (session-id field).\n* Map fields:\n\n  * Title: may come from “task name” or first user message.\n  * Role: map Claude’s `user`, `assistant`, `tool`.\n  * Workspace: if path is embedded; else null.\n* Additionally, check per-repo `.claude` / `.claude.json`:\n\n  * Some setups store “project memory” or limited history there; treat as additional conversations.\n\n**Incremental**\n\n* Watch `~/.claude/projects` for new/updated `.jsonl` files.\n\n### 7.4 Gemini CLI Connector\n\n**Detection**\n\n* `gemini` binary on PATH (`which \"gemini\"` or `gemini-cli`), or `~/.gemini` directory.([GitHub][5])\n\n**Scan**\n\n* Root: `~/.gemini/tmp`.\n* For each child dir `<project-hash>`:\n\n  * Enumerate JSON files:\n\n    * `checkpoint-*.json`, `chat-*.json`, etc.\n* Reconstruction strategy (from logs-prettifier script semantics):([GitHub][5])\n\n  * Checkpoints contain “current conversation state”; chat logs contain message history.\n  * Prefer chat logs; if absent, fallback to checkpoints.\n* Build:\n\n  * `external_id` = directory name + checkpoint id.\n  * `title` = derived from first user message or model-provided session name.\n  * Timestamps = earliest / latest message timestamps.\n\n**Incremental**\n\n* Watch `~/.gemini/tmp` for new directories / files.\n\n### 7.5 Amp Connector\n\n**Detection**\n\n* `amp` CLI on PATH (`npm i -g @sourcegraph/amp` installs it).([marketplace.visualstudio.com][29])\n* `~/.local/share/amp` exists or `%APPDATA%\\amp`.([Amp Code][16])\n\n**Scan**\n\n* Local thread storage is **limited** (most sessions remote).([Reddit][15])\n* Strategy:\n\n  * Inspect `~/.local/share/amp` / `%APPDATA%\\amp`:\n\n    * Any JSON/JSONL logs? (we’ll define a naming convention once we see typical installs).\n  * Inspect VS Code globalStorage for Amp extension (similar to Cline):\n\n    * e.g. `Code/User/globalStorage/sourcegraph.amp/**`.\n* If we find JSON/JSONL per thread:\n\n  * Map them to `NormalizedConversation`.\n* Tag Amp conversations as `partial = true` in metadata.\n\n### 7.6 Cline Connector\n\n**Detection**\n\n* Check for VS Code globalStorage path:\n\n  * Platform-specific pattern resolving to `<vscode-config>/User/globalStorage/saoudrizwan.claude-dev`.([Reddit][7])\n\n**Scan**\n\n* In that directory:\n\n  * Identify per-task directories or files:\n\n    * `taskHistory.json` summarizing tasks (maybe optional if corrupted).([Stack Overflow][17])\n    * A directory per task UUID with:\n\n      * `task_metadata.json`\n      * `ui_messages.json`\n      * `api_conversation_history.json`\n  * If `taskHistory.json` exists:\n\n    * Use as index for tasks (title, created_at).\n  * For each task:\n\n    * Parse `task_metadata.json`:\n\n      * Title, provider, workspace root, etc.\n    * Parse `ui_messages.json` / `api_conversation_history.json`:\n\n      * Build ordered message list; unify user vs agent vs tool roles.\n* `external_id` = task id.\n\n**Incremental**\n\n* Watch globalStorage dir for changes.\n\n### 7.7 OpenCode Connector\n\n**Detection**\n\n* On startup:\n\n  * If `opencode` CLI on PATH (nice but not required).\n  * Scan:\n\n    * Current working dir upward for `.opencode` (project-local).\n    * `$HOME` for `.opencode` or config-specified global DB.([HackMD][8])\n\n**Scan**\n\n* For each `.opencode` dir:\n\n  * Read config (if present) to locate SQLite DB.\n  * Open DB with rusqlite and introspect schema.\n\n    * Likely tables: `sessions`, `messages`, `files`, etc.\n* Map:\n\n  * Each row in `sessions` = `Conversation`.\n  * Each `message` row = `Message`.\n  * Additional tables (e.g., `files`) → `Snippet`s or tags.\n\n**Incremental**\n\n* For SQLite DB, we can’t easily watch per-row changes, but we can:\n\n  * Track DB `mtime` and last imported row id / timestamp per DB.\n  * On change:\n\n    * Query for rows newer than last imported.\n\n---\n\n## 8. Indexer & Synchronization Flow\n\n### 8.1 First Run\n\n1. User runs `agent-search` (TUI command).\n2. App locates config dir (`directories::ProjectDirs` for `coding_agent_search`).([Crates][23])\n3. If DB / index missing:\n\n   * Run **initial detection**:\n\n     * For each connector, call `detect_installation`.\n   * Show small TUI dialog:\n\n     * “Detected: Codex, Cline, Gemini. Index now? [Yes] [Skip]”\n   * Kick off **full scan** in background thread:\n\n     * Progress bar in status bar:\n\n       * “Indexing Codex: 327/1024 sessions…”\n\n### 8.2 Incremental Updates\n\n* For log-file-based sources:\n\n  * Use `notify` watchers on root dirs (`~/.codex`, `~/.gemini/tmp`, `~/.claude/projects`, VS Code globalStorage).([GitHub][22])\n  * Debounce FS events to avoid thrashing.\n* For SQLite-based sources (OpenCode):\n\n  * Periodic polling (e.g., every 60s) for DB `mtime` change.\n* On new/changed source:\n\n  * Re-run corresponding connector `scan_sessions` but with:\n\n    * `since_timestamp` = last import time per source file / DB.\n\n### 8.3 Schema Migrations\n\n* Maintain `schema_version` in a small `meta` table.\n* On binary upgrade:\n\n  * If schema mismatch:\n\n    * Run migration scripts (Rust-implemented).\n    * Optionally rebuild Tantivy index from SQLite.\n\n---\n\n## 9. Installer Design (`curl | bash`)\n\n### 9.1 Goals\n\n* Single-line install inspired by Ultimate Bug Scanner:([GitHub][2])\n\n```bash\ncurl -fsSL https://raw.githubusercontent.com/<you>/coding-agent-search/main/install.sh | bash\n```\n\n* Support `--easy-mode` to:\n\n  * Auto-install all dependencies without prompting.\n  * Auto-enable all detected agents.\n\n### 9.2 Install Script Behavior (Linux/macOS)\n\n**1. Safety & prerequisites**\n\n* `set -euo pipefail`\n* Check for:\n\n  * `curl` or `wget`\n  * `tar`\n  * `uname`, `mktemp`\n* Print what it will do and ask confirmation (unless `--easy-mode`).\n\n**2. Detect OS / arch**\n\n* `uname -s` → `Linux` / `Darwin`.\n* `uname -m` → `x86_64` / `arm64`.\n\n**3. Download binary**\n\n* Determine latest version (github releases API or static `VERSION` file).\n* Download `agent-search-<os>-<arch>.tar.gz`.\n* Verify checksum (SHA-256 baked into script; like UBS does for its modules).([GitHub][2])\n\n**4. Install location**\n\n* Default: `${HOME}/.local/bin/agent-search` (or `~/bin` fallback).\n* Optionally `/usr/local/bin` if user chooses and has sudo.\n\n**5. Dependencies**\n\nWe aim to build a **fully self-contained** binary (bundled SQLite, static linking), so external dependencies are minimal. For extra tools we might optionally use:\n\n* `sqlite3` CLI (for debug)\n* `less` or `bat` (for external viewing)([GitHub][30])\n\nScript logic:\n\n* Detect package manager: `apt`, `dnf`, `pacman`, `brew`, `yum`, `zypper`.\n* For each missing extra:\n\n  * Prompt: “Install sqlite3 with apt? [Y/n]” unless `--easy-mode`.\n\n**6. Post-install**\n\n* Add `${HOME}/.local/bin` to PATH if missing (touch shell rc).\n* Print quickstart:\n\n```text\nRun: agent-search\nOr:  agent-search tui\n```\n\n### 9.3 Windows Installer (PowerShell)\n\n* Equivalent PowerShell command:\n\n```powershell\nirm https://raw.githubusercontent.com/<you>/coding-agent-search/main/install.ps1 | iex\n```\n\n* Steps:\n\n  * Detect architecture via `[Environment]::Is64BitOperatingSystem`.\n  * Download `agent-search-windows-x86_64.zip`.\n  * Extract to `%LOCALAPPDATA%\\Programs\\agent-search`.\n  * Add that directory to user PATH (via registry or `setx`).\n* For Windows lacking proper terminal support:\n\n  * Recommend **Windows Terminal** or WSL; but the binary should still work with standard console.\n\n---\n\n## 10. Agent Auto-Detection Strategy\n\n### 10.1 Executable Detection\n\nUse `which` or `pathsearch` crate to reliably find executables in PATH on all OSes (handles PATHEXT on Windows).([Stack Overflow][28])\n\n* Binaries to probe:\n\n  * `codex`\n  * `amp`\n  * `gemini` or `gemini-cli`\n  * `opencode`\n  * For Claude Code / Cline (more VSCode-embedded), detection will lean on filesystem directories.\n\n### 10.2 Filesystem Heuristics\n\n* Check for each tool's canonical conf/data dirs (see Section 2 table).\n* If path exists **and** contains expected “signature file”:\n\n  * Codex: `~/.codex/config.toml`([GitHub][3])\n  * Gemini: `~/.gemini/tmp` with `checkpoint-*.json`.([GitHub][5])\n  * Claude: `~/.claude/projects` with JSONL.([GitHub][4])\n  * Cline: VS Code globalStorage dir with `taskHistory.json`.([Reddit][7])\n  * Amp: `~/.local/share/amp/secrets.json` or `%APPDATA%\\amp\\secrets.json`.([Amp Code][16])\n  * OpenCode: `.opencode` directories / global config.([HackMD][8])\n\n### 10.3 User-facing Detection UI\n\nOn first run (and accessible via `Settings`):\n\n* Show list:\n\n| Agent       | Detected? | Evidence                           | Enabled? |\n| ----------- | --------- | ---------------------------------- | -------- |\n| Codex CLI   | yes/no    | `codex` in PATH, `~/.codex/...`    | [x]      |\n| Claude Code | yes/no    | `~/.claude/projects`               | [x]      |\n| Gemini CLI  | yes/no    | `~/.gemini/tmp`                    | [x]      |\n| Amp         | yes/no    | `amp` CLI, Amp globalStorage, etc. | [ ]      |\n| Cline       | yes/no    | VSCode globalStorage dir           | [x]      |\n| OpenCode    | yes/no    | `.opencode` dirs / global DB       | [x]      |\n\nUser can toggle connectors on/off; this is stored in config.\n\n---\n\n## 11. Configuration\n\n### 11.1 Config File Layout\n\n* Use `directories::ProjectDirs` to compute platform-correct config directory, e.g.:\n\n  * Linux: `~/.config/coding-agent-search/config.toml`\n  * macOS: `~/Library/Application Support/coding-agent-search/config.toml`\n  * Windows: `%APPDATA%\\coding-agent-search\\config.toml`([Crates][23])\n\nExample `config.toml`:\n\n```toml\n[general]\ntheme = \"dark\"\nenable_tantivy = true\nmax_results = 200\n\n[sqlite]\npath = \"/home/user/.local/share/coding-agent-search/agent_search.db\"\npage_size = 4096\ncache_size_mb = 64\n\n[agents.codex]\nenabled = true\nhome = \"/home/user/.codex\"\n\n[agents.claude_code]\nenabled = true\nprojects_dir = \"/home/user/.claude/projects\"\n\n[agents.gemini_cli]\nenabled = true\nroot = \"/home/user/.gemini/tmp\"\n\n[agents.amp]\nenabled = false\nnote = \"Limited to local cache only\"\n\n[agents.cline]\nenabled = true\nvscode_profile = \"Code\"         # or \"Code - Insiders\"\n\n[agents.opencode]\nenabled = true\nsearch_project_roots = true\nextra_db_paths = []\n```\n\n### 11.2 Advanced Tuning Options\n\n* `tantivy.index_path`, `tantivy.num_indexing_threads`.\n* `search.default_time_range` (e.g., `7d`).\n* `search.min_query_length` for search-as-you-type.\n* `performance.max_conversations` to index; can be unlimited by default.\n\n---\n\n## 12. Testing & Benchmarking Plan\n\n### 12.1 Unit Tests\n\n* For each connector:\n\n  * Synthetic minimal log/DB sample → normalized conversations.\n  * Backwards-compat as upstream tools change (guard by snapshot tests).\n* For SQLite:\n\n  * Schema migrations tested with up/down simulation.\n* For search:\n\n  * Queries returning expected conversations for various filters.\n\n### 12.2 Integration Tests\n\n* End-to-end:\n\n  1. Spin up a temp dir as “home”.\n  2. Place sample logs for Codex, Cline, Gemini, etc.\n  3. Run `agent-search index --full --config test-config.toml`.\n  4. Run `agent-search tui` in non-interactive mode:\n\n     * Feed keystrokes.\n     * Assert on output (e.g., via `crossterm` recording or snapshotting RAT).\n\n### 12.3 Performance Benchmarks\n\nBaseline dataset: e.g.,\n\n* 10k conversations\n* 1M messages\n* Several hundred MB raw logs.\n\nMetrics:\n\n* Full index time with Tantivy only, SQLite only, both.\n* Search latency distribution vs query length and filter complexity.\n* Memory footprint vs dataset size.\n\nUse `criterion` for benchmark harness.\n\n---\n\n## 13. Roadmap\n\n### 13.1 v0 (MVP)\n\n* CLI & TUI skeleton (Ratatui + crossterm).\n* SQLite storage with schema above.\n* Tantivy index:\n\n  * Simple indexing of `content`, `title`, `agent_slug`, `created_at`.\n* Connectors:\n\n  * Codex CLI (session logs)\n  * Cline (VS Code globalStorage)\n  * Gemini CLI (`~/.gemini/tmp`)\n* Installer:\n\n  * `install.sh` (curl | bash) for Linux/macOS.\n  * Manual install instructions for Windows.\n\n### 13.2 v1\n\n* Full connectors:\n\n  * Claude Code (global projects & `.claude` files)\n  * OpenCode (SQLite integration)\n  * Initial Amp support (local caches only).\n* `notify`-based incremental indexer.\n* Filter UI (per-agent, time range, workspace).\n* Config file + dynamic reload (`r` to reload config).\n\n### 13.3 v2+\n\n* Better Amp & Claude Code support as they stabilize history APIs.\n* Export features:\n\n  * `agent-search export --agent codex --format jsonl` etc.\n* “Session merge” features:\n\n  * Combine related threads from different tools for the same repo.\n* Optional vector-embedding index layered on top of Tantivy/FTS for semantic search.\n\n---\n\n## 14. Concrete Implementation Checklist\n\nA very granular build order to actually implement this:\n\n1. **Scaffolding**\n\n   * `cargo new coding-agent-search`\n   * Add dependencies:\n\n     * `ratatui`, `crossterm`, `ratatui-crossterm`\n     * `rusqlite` (with `bundled` + `modern_sqlite` features)([Docs.rs][20])\n     * `tantivy`\n     * `serde`, `serde_json`, `serde_yaml`, `toml`\n     * `directories-next` or `directories`\n     * `notify`\n     * `rayon`\n     * `clap` (derive)([Docs.rs][31])\n     * `which`\n     * `tracing`, `tracing-subscriber`\n     * `color-eyre` or `miette`.\n\n2. **Core modules**\n\n   * Implement `config` with load/save and defaults.\n   * Implement `storage::sqlite`:\n\n     * DB initialization, pragmas, migrations.\n   * Implement `search::tantivy`:\n\n     * schema, index writer, searcher.\n\n3. **Minimal TUI**\n\n   * Basic layout (search bar + list + detail).\n   * Hard-coded dummy data for results.\n\n4. **Codex connector**\n\n   * Env detection, path scanning.\n   * Minimal JSONL parsing and mapping into DB/index.\n\n5. **Cline connector**\n\n   * VS Code path resolution per OS.\n   * Task directory parsing.\n\n6. **Gemini connector**\n\n   * `~/.gemini/tmp` scanning and JSON parsing.\n\n7. **Index orchestration**\n\n   * Full `index` command.\n   * TUI-triggered incremental reindex.\n\n8. **Installer**\n\n   * Implement `install.sh` copying patterns from UBS (easy mode, sha256 verification, module detection).([GitHub][2])\n   * Add GitHub workflow to build release tarballs/zips.\n\n9. **Remaining connectors**\n\n   * Claude Code, OpenCode, Amp.\n\n10. **Polish**\n\n    * Theming, help screen, keybinding docs.\n    * Config toggle for FTS vs Tantivy.\n    * Extensive tests and benchmarks.\n\n---\n\nThis plan should be enough to sit down and start coding the entire system in Rust, with each piece grounded in how the underlying tools really store their histories and in current best practices for Rust TUIs, embedded search, and installer UX.\n\n[1]: https://github.com/quickwit-oss/tantivy?utm_source=chatgpt.com \"Tantivy is a full-text search engine library inspired ... - GitHub\"\n[2]: https://github.com/Dicklesworthstone/ultimate_bug_scanner \"GitHub - Dicklesworthstone/ultimate_bug_scanner:  Industrial-grade static analysis for all popular programming languages.

Project Audit\n\n### Architecture\nCASS is a **Rust CLI tool** (edition 2024, v0.1.61) providing full-text search across AI coding agent sessions. It indexes conversations from 10+ agent types and provides structured output via multiple robot-friendly formats.\n\n### Key Files\n| File | Purpose |\n|------|---------|\n| `src/lib.rs` (~420KB) | Main CLI module: command definitions, output formatting, RobotFormat enum |\n| `src/search/query.rs` | SearchHit struct, SearchResult, query execution |\n| `Cargo.toml` | Binary \"cass\", serde + serde_json dependencies |\n\n### Existing Output Formats\nCASS already supports **4 robot output formats** via `--robot-format`:\n1. **json** (default) - Pretty-printed JSON object (`serde_json::to_string_pretty`)\n2. **jsonl** - Newline-delimited JSON (one hit per line + optional `_meta` header)\n3. **compact** - Single-line JSON (`serde_json::to_string`)\n4. **sessions** - Bare session paths (one per line, for chaining)\n\nPlus **3 human-readable formats** via `--display`:\n- table, lines, markdown\n\n### Serialization Patterns\n- **serde + serde_json** for all JSON output\n- `SearchHit` struct with `#[derive(serde::Serialize)]`\n- `filter_hit_fields()` → `apply_content_truncation()` → `clamp_hits_to_budget()` pipeline\n- Output via `serde_json::to_string_pretty(&payload)` (Json) or `serde_json::to_string(&hit)` (Jsonl/Compact)\n\n### Key Data Structures\n\n```rust\n// src/search/query.rs:758\npub struct SearchHit {\n    pub title: String,\n    pub snippet: String,\n    pub content: String,\n    pub score: f32,\n    pub source_path: String,\n    pub agent: String,\n    pub workspace: String,\n    pub workspace_original: Option<String>,  // skip_serializing_if None\n    pub created_at: Option<i64>,\n    pub line_number: Option<usize>,\n    pub match_type: MatchType,\n    pub source_id: String,    // default: \"local\"\n    pub origin_kind: String,  // default: \"local\"\n    pub origin_host: Option<String>,  // skip_serializing_if None\n}\n```\n\n---\n\n## 2. Output Analysis\n\n### Sample Output Sizes (Actual Measurements)\n\n| Command | Hits | JSON Bytes | TOON Bytes | Byte Savings | JSON Tokens | TOON Tokens | Token Savings |\n|---------|------|-----------|------------|--------------|-------------|-------------|---------------|\n| `cass health --json` | N/A | 634 | 489 | 22.9% | ~115 | ~97 | **15.7%** |\n| `cass capabilities --json` | N/A | 859 | 573 | 33.3% | ~160 | ~136 | **15.0%** |\n| `search --limit 3` | 3 | 1,840 | 1,123 | 38.9% | ~359 | ~263 | **26.7%** |\n| `search --limit 20 --fields minimal` | 13 | 4,378 | N/A | N/A | ~913 | ~698 | **23.5%** |\n| `search --limit 30 --fields summary` | 13 | 11,112 | N/A | N/A | ~2,307 | ~1,865 | **19.2%** |\n| `search --limit 20 --max-content-length 100` | 13 | 10,291 | 9,035 | 12.2% | ~2,065 | ~1,879 | **9.0%** |\n\n### Key Insight: Value-Heavy vs Key-Heavy Data\n\n**Why savings are lower than UBS (9-27% vs UBS's 34-50%)**:\n\nCASS search results contain **long string values** (file paths, content snippets, titles) that dominate the token count. TOON's primary savings mechanism is eliminating repeated key names in tabular data, but when values are 50-200 characters and keys are 5-15 characters, key elimination provides proportionally less savings.\n\nCompare with UBS findings where values are short (`\"critical\"`, `3`, `\"Use Number.isNaN(x)\"`), making key repetition the dominant overhead.\n\n### Tabular Data Candidates (MODERATE opportunity)\n\n1. **`hits` array** (uniform SearchHit fields)\n   - TOON: `hits[N]{agent,score,source_path,line_number,...}:` + CSV-like rows\n   - Savings limited by long path/content values in each row\n   - **Best with `--fields minimal`**: 23.5% savings (short values only)\n\n2. **`features` array** (capabilities command - uniform strings)\n   - TOON: Already compresses well: `features[22]: json_output,jsonl_output,...`\n   - **15% savings** (already compact)\n\n3. **`connectors` array** (capabilities - short strings)\n   - TOON: `connectors[10]: codex,claude_code,gemini,...`\n   - Minimal overhead in JSON anyway\n\n### Key Folding Opportunities\n\n- `state._meta.data_dir`, `state._meta.db_path`, `state._meta.timestamp`\n- `state.database.conversations`, `state.database.exists`, `state.database.messages`\n- `state.index.exists`, `state.index.fresh`, `state.index.stale`\n- `state.pending.sessions`, `state.pending.watch_active`\n\n### TOON Output Samples\n\n**Search output (3 hits, --fields summary):**\n```\ncount: 3\ncursor: null\nhits[3]{agent,content,created_at,line_number,match_type,origin_kind,score,snippet,source_id,source_path,title,workspace}:\n  claude_code,commit changes to git repo,1768525988702,1,exact,local,55.169,commit changes to git repo,local,/home/ubuntu/.claude/projects/.../ce16a69a.jsonl,commit changes to git repo,/data/projects/beads_rust\n  claude_code,\"[Tool: Bash - Verify commit success]\",1768532433520,10,exact,local,44.967,\"[Tool: Bash - Verify commit success]\",local,/home/ubuntu/.claude/projects/.../27545ba7.jsonl,commit changes to git repo,/data/projects/beads_rust\n  claude_code,\"[Tool: Bash - Verify commit succeeded]\",1768526016823,11,exact,local,44.933,\"[Tool: Bash - Verify commit succeeded]\",local,/home/ubuntu/.claude/projects/.../ce16a69a.jsonl,commit changes to git repo,/data/projects/beads_rust\nhits_clamped: false\nlimit: 5\nmax_tokens: null\noffset: 0\nquery: git commit\nrequest_id: null\ntotal_matches: 3\n```\n\n**Capabilities output:**\n```\ncrate_version: 0.1.61\napi_version: 1\ncontract_version: \"1\"\nfeatures[22]: json_output,jsonl_output,robot_meta,time_filters,field_selection,...\nconnectors[10]: codex,claude_code,gemini,opencode,amp,cline,aider,cursor,chatgpt,pi_agent\nlimits:\n  max_limit: 10000\n  max_content_length: 0\n  max_fields: 50\n  max_agg_buckets: 10\n```\n\n---\n\n## 3. Integration Assessment\n\n### Complexity Rating: **Simple**\n\nCASS is Rust with serde, and the format dispatch is a clean `match format {}` block.\n\n### Recommended Approach: **Use toon_rust as a library crate**\n\n`toon_rust` already exposes a Rust library. Prefer a direct crate dependency so CASS can encode/decode without spawning a subprocess:\n\n```toml\n# Cargo.toml\ntoon_rust = { path = \"../toon_rust\" }\n```\n\n```rust\nRobotFormat::Toon => {\n    let json_value = serde_json::to_value(&payload)?;\n    let toon_str = toon_rust::encode(json_value, None);\n    println!(\"{toon_str}\");\n}\n```\n\nThis avoids process spawning, removes a binary dependency, and guarantees we use the toon_rust implementation.\n\n### Fallback (Non-Rust only): toon_rust tru binary\n\nIf a non-Rust tool needs TOON, use the toon_rust `tru` binary explicitly (never the Node.js CLI).\n\n### Key Integration Points\n\n| File/Location | Change Required |\n|---------------|-----------------|\n| `src/lib.rs:853` | Add `Toon` variant to `RobotFormat` enum |\n| `src/lib.rs:4302-4610` | Add `RobotFormat::Toon` match arm in `output_robot_results()` |\n| `src/lib.rs:182` | Already handles `robot_format: Option<RobotFormat>` |\n| `src/lib.rs:3624` | Format resolution logic (no changes needed) |\n| `Cargo.toml` | Optionally add `toon_rust` path dependency (Pattern B only) |\n\n### Dependencies\n- Preferred: `toon_rust` crate + existing `serde`/`serde_json`\n- Optional fallback (non-Rust): toon_rust `tru` binary (use `TOON_TRU_BIN` if PATH conflicts)\n\n### Backwards Compatibility\n- Zero risk: new `--robot-format toon` value, does not affect existing formats\n- `--json` still defaults to `RobotFormat::Json`\n- No breaking changes to any existing output\n\n---\n\n## 4. Token Savings Projections\n\n| Usage Scenario | JSON Tokens | TOON Tokens | Savings |\n|----------------|-------------|-------------|---------|\n| Health check | ~115 | ~97 | ~16% |\n| Capabilities query | ~160 | ~136 | ~15% |\n| Small search (3 hits, full fields) | ~359 | ~263 | ~27% |\n| Medium search (13 hits, minimal fields) | ~913 | ~698 | ~24% |\n| Medium search (13 hits, summary fields) | ~2,307 | ~1,865 | ~19% |\n| Large search (13 hits, full content) | ~2,065 | ~1,879 | ~9% |\n| Projected: 50 hits, full fields | ~8,000+ | ~6,800+ | ~15% |\n| Projected: 50 hits, minimal fields | ~3,500+ | ~2,700+ | ~23% |\n\n**Key finding**: Token savings are inversely correlated with content field length. Best results with `--fields minimal` or `--max-content-length` limits.\n\n**Recommendation**: When agents use `--robot-format toon`, they should also use `--fields minimal` or `--fields summary` to maximize compression benefits.\n\n---\n\n## 5. Special Considerations\n\n### Language-Specific Notes\n- CASS is **Rust** (edition 2024) with serde derives on all output types\n- Use `toon_rust` as a library crate (already available)\n- Avoid subprocesses; reserve the `tru` binary for non-Rust tools only\n- `SearchHit` has `#[serde(skip_serializing_if = \"Option::is_none\")]` on optional fields, which TOON handles naturally (omitted fields = no row entry)\n\n### TOON Effectiveness Factors\n- **HIGH savings**: Commands with short, structured values (health, capabilities, status)\n- **MODERATE savings**: Searches with `--fields minimal/summary` (short per-hit values)\n- **LOW savings**: Searches with full content fields (long strings dominate token count)\n\n### Implementation Order\n1. Add `Toon` variant to `RobotFormat` enum\n2. Add match arm calling `toon_rust::encode(...)`\n3. Add `--robot-format toon` to CLI help/docs\n4. Test with representative queries at various field/content limits\n5. Consider adding `--fields` suggestions when `--robot-format toon` is used\n6. Document that `--fields minimal` + `--robot-format toon` is optimal for token savings\n\n### Risk Assessment\n- **Low risk**: New format variant, no existing behavior changes\n- **Dependency risk**: Adds `toon_rust` crate (path/git dependency)\n- **Mitigation**: Fallback to JSON with warning if `toon_rust::encode` fails\n- **Performance**: No subprocess overhead\n\n---\n\n## 6. Deliverables Checklist\n\n- [x] RESEARCH_FINDINGS.md created (this file)\n- [ ] Project-level beads created in .beads/ (see below)\n- [ ] bd-308 (Integrate TOON into cass) updated with actual findings\n\n---\n\n## 7. Recommended Project-Level Beads\n\nThe following beads should be created for CASS TOON integration:\n\n1. **cass-toon-enum**: Add `Toon` variant to `RobotFormat` enum in lib.rs:853\n2. **cass-toon-output**: Implement TOON output in `output_robot_results()` match block\n3. **cass-toon-fallback**: Graceful fallback to JSON on toon_rust encode errors\n4. **cass-toon-test**: Add integration tests for `--robot-format toon` output\n5. **cass-toon-docs**: Update CLI help text and README with TOON format option\n6. **cass-toon-fields-hint**: Suggest `--fields minimal` when TOON format is used (optional UX improvement)\n\n---\n\n## 8. Comparison with UBS Integration\n\n| Aspect | UBS | CASS |\n|--------|-----|------|\n| Language | Bash | Rust |\n| Savings (typical) | 34-50% | 15-27% |\n| Best case | 65 uniform findings | minimal-field searches |\n| Integration method | toon_rust `tru` binary | toon_rust crate |\n| Complexity | Simple | Simple |\n| Tier | 1 (High Impact) | 2 (Moderate Impact) |\n| Primary savings driver | Tabular findings array | Eliminating hit field keys |\n| Limiting factor | None (short values) | Long string values in hits |\n"

    "content": "# The Definitive Guide to High-Performance CLI and Automation Tools with Rust (mid-2025 Edition)\n\nThis guide synthesizes modern best practices for building blazingly fast, user-friendly, and production-ready CLI tools and automation systems with the **latest Rust nightly**, clap, anyhow, and tokio. It moves beyond basic argument parsing to provide battle-tested patterns for real-world command-line applications.\n\n## Prerequisites & Toolchain Configuration\n\nEnsure your environment uses the **current Rust nightly** (pinned via `rust-toolchain.toml`) plus the latest crate releases (wildcard constraints) for **clap**, **anyhow**, and **tokio**. The 2024 edition provides better async ergonomics and should be your default.\n\n```toml\n# Cargo.toml - Base configuration for CLI tools (nightly + latest crates)\n[package]\nname = \"myctl\"\nversion = \"0.1.0\"\nedition = \"2024\"\nauthors = [\"Your Name <you@example.com>\"]\ndescription = \"A blazingly fast CLI tool\"\nlicense = \"MIT OR Apache-2.0\"\nrepository = \"https://github.com/yourusername/myctl\"\nkeywords = [\"cli\", \"automation\", \"tool\"]\ncategories = [\"command-line-utilities\"]\n\n[[bin]]\nname = \"myctl\"\npath = \"src/main.rs\"\n\n[dependencies]\n# Core CLI framework\nclap = { version = \"*\", features = [\"derive\", \"cargo\", \"env\", \"unicode\", \"wrap_help\"] }\nclap_complete = \"*\"\nclap_mangen = \"*\"\n\n# Error handling\nanyhow = \"*\"\nthiserror = \"*\"\n\n# Async runtime\ntokio = { version = \"*\", features = [\"rt-multi-thread\", \"macros\", \"fs\", \"process\", \"io-util\", \"time\", \"signal\"] }\n\n# Serialization\nserde = { version = \"*\", features = [\"derive\"] }\nserde_json = \"*\"\ntoml = \"*\"\n\n# User interaction\ndialoguer = \"*\"\nindicatif = \"*\"\nconsole = \"*\"\ncolored = \"*\"\n\n# System interaction\ndirectories = \"*\"\nwhich = \"*\"\nshell-words = \"*\"\n\n# HTTP client for API interactions\nreqwest = { version = \"*\", features = [\"json\", \"rustls-tls\"], default-features = false }\n\n# Logging\ntracing = \"*\"\ntracing-subscriber = { version = \"*\", features = [\"env-filter\", \"json\"] }\n\n[dev-dependencies]\nassert_cmd = \"*\"\npredicates = \"*\"\ntempfile = \"*\"\ninsta = { version = \"*\", features = [\"yaml\", \"json\"] }\n\n[profile.release]\nlto = true\ncodegen-units = 1\nstrip = true\npanic = \"abort\"\nopt-level = \"z\"  # Optimize for binary size\n```\n\n### Essential Development Tools\n\n```bash\n# Install development tools\ncargo install cargo-binstall    # Install binaries faster\ncargo install cargo-dist        # Cross-platform binary distribution\ncargo install cargo-insta       # Snapshot testing\ncargo install hyperfine         # CLI benchmarking\ncargo install cargo-bloat       # Analyze binary size\n\n# Platform-specific tools\ncargo binstall cargo-zigbuild   # Better cross-compilation\ncargo binstall cross            # Docker-based cross-compilation\n```\n\n---\n\n## 1.

Error Handling with Anyhow\n\nCLI tools need excellent error messages. Anyhow provides the perfect balance of ergonomics and informativeness.\n\n### ✅ DO: Use Context for Better Error Messages\n\n```rust\nuse anyhow::{anyhow, bail, Context, Result};\nuse std::fs;\nuse std::path::Path;\n\npub async fn load_config(path: &Path) -> Result<Config> {\n    // Add context to filesystem operations\n    let contents = fs::read_to_string(path)\n        .with_context(|| format!(\"Failed to read config file at {}\", path.display()))?;\n    \n    // Add context to parsing operations\n    let config: Config = toml::from_str(&contents)\n        .with_context(|| format!(\"Invalid TOML in config file {}\", path.display()))?;\n    \n    // Validate with custom errors\n    validate_config(&config)\n        .with_context(|| \"Configuration validation failed\")?;\n    \n    Ok(config)\n}\n\nfn validate_config(config: &Config) -> Result<()> {\n    if config.timeout_seconds == 0 {\n        bail!(\"Timeout must be greater than 0\");\n    }\n    \n    if config.endpoints.is_empty() {\n        return Err(anyhow!(\"At least one endpoint must be configured\"));\n    }\n    \n    for (name, endpoint) in &config.endpoints {\n        if endpoint.url.scheme() != \"https\" && !config.allow_insecure {\n            bail!(\n                \"Endpoint '{}' uses insecure protocol '{}'. \\\n                 Use HTTPS or set 'allow_insecure = true'\",\n                name,\n                endpoint.url.scheme()\n            );\n        }\n    }\n    \n    Ok(())\n}\n```\n\n### ✅ DO: Create Helpful Error Displays\n\n```rust\nuse console::style;\nuse std::fmt::Write;\n\npub fn display_error(err: &anyhow::Error) -> String {\n    let mut output = String::new();\n    \n    // Primary error\n    writeln!(\n        &mut output, \n        \"{} {}\", \n        style(\"Error:\").red().bold(),\n        err\n    ).unwrap();\n    \n    // Chain of causes\n    let mut source = err.source();\n    while let Some(cause) = source {\n        writeln!(\n            &mut output,\n            \"  {} {}\",\n            style(\"Caused by:\").yellow(),\n            cause\n        ).unwrap();\n        source = cause.source();\n    }\n    \n    // Add helpful suggestions based on error type\n    if let Some(suggestion) = suggest_fix(err) {\n        writeln!(\n            &mut output,\n            \"\\n{} {}\",\n            style(\"Suggestion:\").green(),\n            suggestion\n        ).unwrap();\n    }\n    \n    output\n}\n\nfn suggest_fix(err: &anyhow::Error) -> Option<&'static str> {\n    let msg = err.to_string();\n    \n    if msg.contains(\"EACCES\") || msg.contains(\"Permission denied\") {\n        Some(\"Try running with elevated permissions (sudo on Unix)\")\n    } else if msg.contains(\"ENOENT\") || msg.contains(\"No such file\") {\n        Some(\"Check if the file path is correct and the file exists\")\n    } else if msg.contains(\"EADDRINUSE\") || msg.contains(\"Address already in use\") {\n        Some(\"Another process is using this port.

The key principles to remember:\n\n1. **User Experience First** - Fast startup, helpful errors, beautiful output\n2. **Robustness** - Handle errors gracefully, validate inputs, test thoroughly  \n3. **Performance** - Profile before optimizing, use async wisely, minimize allocations\n4. **Flexibility** - Support multiple platforms, output formats, and use cases\n5. **Maintainability** - Structure code well, document thoroughly, automate releases\n\nThe Rust ecosystem for CLI tools continues to evolve rapidly. Stay updated with the latest crate versions and patterns, but always prioritize user experience and reliability over using the newest features.\n\nFor more examples and the latest updates to this guide, visit the companion repository at [github.com/rust-cli/definitive-guide](https://github.com/rust-cli/definitive-guide).\n"

    "content": "# Semantic Search Implementation: Bead Structure & Elaboration\n\n## Overview\n\nThis document elaborates on the semantic search plan and defines the complete bead (task) hierarchy for implementation. It's designed to be self-contained so any developer can pick up the work.\n\n## Design Review: Optimizations Applied\n\n### Critical Fixes Applied During Review\n\n| Issue | Bead | Fix Applied |\n|-------|------|-------------|\n| Missing Unicode normalization | `8q8f` | Added NFC normalization as first step in canonicalization |\n| Missing role field for filter parity | `cyra`, `vwxq` | Added `Role: u8` to VectorRow for user/assistant filtering |\n| Missing IndexBuilding state | `vh6q` | Added state for when model is ready but index is being built |\n| Misleading dialog text | `44pw` | Fixed text to accurately describe HuggingFace download |\n| Non-deterministic RRF | `rzrv` | Added explicit tie-breaking rules for reproducible results |\n| No SIMD optimization note | `tn4t` | Added requirement for SIMD-friendly patterns and alignment |\n| No model upgrade path | `94pe` | Added version detection and index migration on model change |\n| No offline install option | `3e28` | Added `--from-file` option for air-gapped environments |\n| Missing determinism tests | `3qvr`, `c8f8` | Added Unicode and tie-breaking determinism tests |\n\n---\n\n### 1. Hash Fallback Strategy (Validated)\n**Decision**: ML embeddings as primary, hash as explicit fallback only.\n\n**Why not ship hash-first?** Hash \"semantic\" search is misleading - it's really just keyword overlap with different scoring. Users would form a negative impression. Better to gate behind consent and deliver the real thing.\n\n**Fallback use case**: `CASS_SEMANTIC_EMBEDDER=hash` for air-gapped environments or users who want instant results without download.\n\n### 2. Vector Index Format (Validated)\n**Decision**: Custom `.cvvi` binary format rather than SQLite virtual table or Arrow.\n\n**Why?** Our use case is narrow: mmap a contiguous vector array, scan with dot products, filter by inline metadata. SQLite's rowid joins would be slower. Arrow adds 5MB+ dependency for features we don't need.\n\n**Format is right-sized**: Header with CRC32, fixed-size rows with filter metadata, contiguous f16 vector slab.\n\n### 3. Inline Filter Metadata (Critical)\n**Decision**: Store `agent_id`, `workspace_id`, `source_id`, `created_at_ms` per vector row.\n\n**Why this matters**: Without inline metadata, semantic search requires DB joins per candidate. For 50k vectors, that's 50k SQLite lookups vs. inline integer comparisons. ~100x faster.\n\n**Space cost**: ~24 bytes per row × 50k = 1.2MB. Worth it.\n\n### 4. Chunking Strategy (Simplified)\n**Original**: Head/middle/tail chunking for long messages.\n\n**Optimization**: Make chunking optional and simple. Most agent messages are <2000 chars. Only 5-10% need chunking. Default: single chunk, truncated at 2000 chars canonical. Optional: enable multi-chunk for large corpus users.\n\n**Why simplify?** Chunking adds complexity (chunk deduplication, score aggregation, UI for chunk navigation). Ship without it first, add based on user feedback.\n\n### 5. Consent Flow (Validated)\n**Decision**: TUI prompt on first Alt+S to SEM/HYB when model not installed.\n\n**Why this is optimal**:\n- Non-blocking: prompt only appears when user actually wants semantic\n- Single-keypress action: D to download, H for hash, Esc to cancel\n- Respects user agency: no surprise downloads\n- Remembers choice: once downloaded, never prompts again\n\n### 6. Diversity Penalty (Deferred)\n**Original**: Optional diversity penalty to demote same-source clusters.\n\n**Optimization**: Remove from initial implementation. RRF already provides some diversity naturally. Add later if users report clustering issues.\n\n**Why defer?** It's a tuning knob that most users won't understand. Better to ship clean RRF and add diversity as a power-user option.\n\n### 7. Query Cache (Essential)\n**Decision**: Include LRU cache for query embeddings.\n\n**Why essential**: Query embedding takes ~15ms. Users often re-run same query (typo fix, mode change). Cache hit = 0ms instead of 15ms. Significant UX improvement.\n\n---\n\n## Dependency Graph\n\n```\n                    ┌─────────────────┐\n                    │  sem.emb.trait  │ Layer 0: Foundation\n                    └────────┬────────┘\n                             │\n              ┌──────────────┼──────────────┐\n              │              │              │\n              ▼              ▼              ▼\n     ┌────────────┐  ┌─────────────┐  ┌────────────┐\n     │sem.emb.hash│  │sem.emb.canon│  │sem.vec.fmt │ Layer 1: Core\n     └──────┬─────┘  └──────┬──────┘  └─────┬──────┘\n            │               │               │\n            │               ▼               │\n            │        ┌─────────────┐        │\n            │        │sem.emb.ml   │        │\n            │        └──────┬──────┘        │\n            │               │               │\n            ▼               │               ▼\n     ┌──────────────────────┴───────────────────────┐\n     │                  sem.vec.ops                  │ Layer 2: Storage\n     └─────────────────────┬────────────────────────┘\n                           │\n              ┌────────────┴────────────┐\n              │                         │\n              ▼                         ▼\n     ┌────────────────┐        ┌───────────────┐\n     │  sem.vec.filt  │        │ sem.mod.core  │ Layer 3: Features\n     └───────┬────────┘        └───────┬───────┘\n             │                         │\n             └────────────┬────────────┘\n                          │\n                          ▼\n              ┌───────────────────────┐\n              │     hyb.search        │ Layer 4: Search\n              └───────────┬───────────┘\n                          │\n              ┌───────────┼───────────┐\n              │           │           │\n              ▼           ▼           ▼\n        ┌─────────┐ ┌─────────┐ ┌─────────┐\n        │ hyb.rrf │ │hyb.rank │ │hyb.filt │ Layer 5: Hybrid\n        └────┬────┘ └────┬────┘ └────┬────┘\n             │           │           │\n             └───────────┴───────────┘\n                         │\n         ┌───────────────┼───────────────┐\n         │               │               │\n         ▼               ▼               ▼\n   ┌───────────┐  ┌────────────┐  ┌────────────┐\n   │tui.sem.*  │  │cli.models  │  │cli.search  │ Layer 6: Interface\n   └───────────┘  └────────────┘  └────────────┘\n                         │\n                         ▼\n              ┌───────────────────────┐\n              │      tst.sem.*        │ Layer 7: Testing\n              └───────────────────────┘\n```\n\n---\n\n## Bead Definitions\n\n### Layer 0: Foundation\n\n#### sem.emb.trait\n**Type**: task | **Priority**: P1 (high)\n\n**Purpose**: Define the Embedder trait that all embedding implementations must satisfy.\n\n**Background**: The trait abstraction allows us to swap embedders (hash vs ML) transparently. This is critical for the consent-gated download flow where we start with hash and upgrade to ML.\n\n**Deliverables**:\n- `src/search/embedder.rs` with `Embedder` trait\n- `embed(&self, text: &str) -> Result<Vec<f32>>`\n- `embed_batch(&self, texts: &[&str]) -> Result<Vec<Vec<f32>>>`\n- `dimension(&self) -> usize`\n- `id(&self) -> &str` (for cache invalidation)\n- `is_semantic(&self) -> bool` (true=ML, false=hash)\n\n**Acceptance criteria**:\n- Trait compiles and is exported from `search` module\n- Documentation explains each method's contract\n- No external dependencies (pure trait definition)\n\n---\n\n### Layer 1: Core Components\n\n#### sem.emb.hash\n**Type**: task | **Priority**: P1 | **Depends on**: sem.emb.trait\n\n**Purpose**: Implement FNV-1a feature hashing embedder as deterministic fallback.\n\n**Background**: Hash embeddings are not \"true\" semantic (they're keyword overlap with random projection). But they're:\n- Instant (no model loading)\n- Deterministic (reproducible)\n- Zero network dependency\nUsed when: (a) ML model not installed, (b) user explicitly opts for hash mode.\n\n**Key implementation details**:\n```rust\n// FNV-1a hash for tokens\nfn hash_token(token: &str) -> u64 {\n    let mut h: u64 = 0xcbf29ce484222325;\n    for byte in token.as_bytes() {\n        h ^= u64::from(*byte);\n        h = h.wrapping_mul(0x100000001b3);\n    }\n    h\n}\n```\n- Tokenization: lowercase, split on non-alphanumeric, filter len >= 2\n- L2 normalization required for cosine similarity\n\n**Acceptance criteria**:\n- `HashEmbedder` implements `Embedder`\n- Deterministic: same input always produces same output\n- Output is L2 normalized (norm = 1.0)\n- Dimension matches configuration (default 384)\n\n---\n\n#### sem.emb.canon\n**Type**: task | **Priority**: P1 | **Depends on**: sem.emb.trait\n\n**Purpose**: Implement canonicalization pipeline for consistent embedding input.\n\n**Background**: Raw agent logs contain noise that hurts embedding quality:\n- Markdown formatting (`**bold**`, `[links](url)`)\n- Huge code blocks with repetitive patterns\n- Tool call transcripts\n- Progress indicators\n\nCanonicalization produces a clean, consistent text for embedding.\n\n**Algorithm**:\n1. Strip markdown formatting (keep text content)\n2. Collapse code blocks: keep first 20 + last 10 lines, replace middle with `[code omitted]`\n3. Normalize whitespace (collapse runs, trim)\n4. Filter low-signal content (\"OK\", \"Done.\", empty strings)\n5. Truncate to MAX_EMBED_CHARS (default 2000)\n\n**Critical**: Canonicalization must be deterministic! Content hash depends on it.\n\n**Configuration**:\n```bash\nCASS_SEM_MAX_CHARS=2000\nCASS_SEM_CODE_HEAD_LINES=20\nCASS_SEM_CODE_TAIL_LINES=10\n```\n\n**Acceptance criteria**:\n- `canonicalize_for_embedding(raw: &str) -> String`\n- `content_hash(raw: &str) -> [u8; 32]` uses canonical text\n- Deterministic (same input = same output)\n- Handles edge cases (empty, all-code, no-code, unicode)\n\n---\n\n#### sem.vec.fmt\n**Type**: task | **Priority**: P1 | **Depends on**: none (parallel with embedder)\n\n**Purpose**: Design and implement the CVVI binary vector index format.\n\n**Background**: We need persistent vector storage that's:\n- Fast to load (mmap-friendly)\n- Compact (f16 quantization)\n- Self-describing (embedder ID in header)\n- Corruption-resistant (CRC32, atomic writes)\n\n**Binary format**:\n```\nHeader (variable size):\n  Magic: \"CVVI\" (4 bytes)\n  Version: u16\n  EmbedderID length: u16\n  EmbedderID: string\n  Dimension: u32\n  Quantization: u8 (0=f32, 1=f16)\n  Count: u32\n  HeaderCRC32: u32\n\nRows (Count × ROW_SIZE bytes, fixed):\n  MessageID: u64          # Stable SQLite PK\n  CreatedAtMs: i64        # For time filtering + recency\n  AgentID: u32            # For agent filtering\n  WorkspaceID: u32        # For workspace filtering\n  SourceID: u32           # For source filtering\n  ChunkIdx: u8            # 0 for single-chunk\n  VecOffset: u64          # Offset into vector slab\n  ContentHash: [u8; 32]   # SHA256(canonical)\n\nVector slab (Count × Dimension × bytes_per_quant):\n  Contiguous f16/f32 values\n```\n\n**Why MessageID instead of (source_path, msg_idx)?**\n- More stable across file moves\n- Works for remote sources where paths differ\n- Simpler joins with SQLite\n\n**Acceptance criteria**:\n- Header parsing/writing with version compatibility\n- CRC32 validation on load\n- Documented format in code comments\n- Endianness: little-endian throughout\n\n---\n\n### Layer 2: Storage & Operations\n\n#### sem.vec.ops\n**Type**: task | **Priority**: P1 | **Depends on**: sem.vec.fmt, sem.emb.hash\n\n**Purpose**: Implement vector index operations (create, load, save, search).\n\n**Core operations**:\n1. **Create**: Build index from embeddings + metadata\n2. **Load**: mmap from disk, validate header\n3. **Save**: Atomic write (temp → fsync → rename)\n4. **Search**: Brute-force dot product with filter\n\n**Atomic write pattern**:\n```rust\nfn save(&self, path: &Path) -> Result<()> {\n    let temp = path.with_extension(\"cvvi.tmp\");\n    // Write to temp\n    let mut f = File::create(&temp)?;\n    self.write_to(&mut f)?;\n    f.sync_all()?;\n    // fsync directory\n    File::open(temp.parent().unwrap())?.sync_all()?;\n    // Atomic rename\n    std::fs::rename(&temp, path)?;\n    Ok(())\n}\n```\n\n**f16 quantization**:\n- Use `half` crate for f16 ↔ f32 conversion\n- Quantize on write, dequantize on read\n- Quality loss is negligible for cosine similarity\n\n**Acceptance criteria**:\n- Roundtrip test: save → load preserves all data\n- Atomic write: crash during write doesn't corrupt\n- mmap loading for large indices\n- f16 vs f32 rankings are equivalent (same top-k)\n\n---\n\n#### sem.vec.filt\n**Type**: task | **Priority**: P2 | **Depends on**: sem.vec.ops\n\n**Purpose**: Implement inline filter parity for semantic search.\n\n**Background**: Existing cass filters (agent, workspace, source, time) must work identically in semantic mode. Users expect F10 cycling to work.\n\n**Implementation**:\n```rust\npub struct SemanticFilter {\n    pub agents: Option<HashSet<u32>>,\n    pub workspaces: Option<HashSet<u32>>,\n    pub sources: Option<HashSet<u32>>,\n    pub created_from: Option<i64>,  // ms timestamp\n    pub created_to: Option<i64>,\n}\n\nimpl SemanticFilter {\n    pub fn matches(&self, row: &VectorRow) -> bool {\n        // Fast integer comparisons, no DB lookup\n        if let Some(agents) = &self.agents {\n            if !agents.contains(&row.agent_id) { return false; }\n        }\n        // ... similar for workspace, source, time\n        true\n    }\n}\n```\n\n**Conversion**: Need to map existing `SearchFilters` (uses string agent names) to `SemanticFilter` (uses integer IDs). Lookup table built at startup.\n\n**Acceptance criteria**:\n- `SemanticFilter::from_search_filters()` conversion\n- Filter matches work correctly for all filter types\n- No DB queries during filter evaluation\n- Performance: <1ms for 50k candidates\n\n---\n\n### Layer 3: ML Embedder & Model Management\n\n#### sem.emb.ml\n**Type**: task | **Priority**: P1 | **Depends on**: sem.emb.trait, sem.emb.canon\n\n**Purpose**: Integrate fastembed-rs for real ML embeddings.\n\n**Model**: `sentence-transformers/all-MiniLM-L6-v2`\n- 384 dimensions\n- ~23MB ONNX model\n- ~15ms per embedding on CPU\n- Good quality for code/technical content\n\n**Integration**:\n```rust\nuse fastembed::{TextEmbedding, EmbeddingModel, InitOptions};\n\npub struct FastEmbedder {\n    model: TextEmbedding,\n    id: String,\n}\n\nimpl FastEmbedder {\n    pub fn new(model_path: &Path) -> Result<Self> {\n        let model = TextEmbedding::try_new(InitOptions {\n            model_name: EmbeddingModel::AllMiniLML6V2,\n            cache_dir: model_path.to_path_buf(),\n            show_download_progress: false, // We handle progress\n            ..Default::default()\n        })?;\n        Ok(Self { model, id: \"minilm-384\".into() })\n    }\n}\n```\n\n**Important**: Model loading should NOT auto-download! We control downloads via model_manager.\n\n**Acceptance criteria**:\n- `FastEmbedder` implements `Embedder`\n- Loads from local cache only (no auto-download)\n- Returns error if model not present\n- `is_semantic()` returns true\n\n---\n\n#### sem.mod.core\n**Type**: task | **Priority**: P2 | **Depends on**: sem.emb.ml\n\n**Purpose**: Implement complete model management (manifest, state machine, download, verify).\n\n**This is a larger bead combining**: manifest, state machine, download, verification.\n\n**Model manifest** (`models.manifest.toml` in repo):\n```toml\n[[models]]\nid = \"all-minilm-l6-v2\"\nrepo = \"sentence-transformers/all-MiniLM-L6-v2\"\nrevision = \"e4ce9877abf3edfe10b0d82785e83bdcb973e22e\"  # Pinned!\nfiles = [\n    { name = \"model.onnx\", sha256 = \"...\", size = 22713856 },\n    { name = \"tokenizer.json\", sha256 = \"...\", size = 711396 },\n    { name = \"config.json\", sha256 = \"...\", size = 612 },\n]\nlicense = \"Apache-2.0\"\n```\n\n**State machine**:\n```rust\npub enum ModelState {\n    NotInstalled,\n    NeedsConsent,\n    Downloading { progress_pct: u8, bytes: u64, total: u64 },\n    Verifying,\n    Ready,\n    Disabled { reason: String },\n    VerificationFailed { reason: String },\n}\n```\n\n**Download system**:\n- Resumable (HTTP Range header)\n- Progress reporting via channel\n- Exponential backoff on failure (3 retries)\n- Timeout: 5 minutes per file\n\n**Verification + atomic install**:\n- Download to `models/<name>.downloading/`\n- Verify SHA256 for each file\n- Atomic rename to `models/<name>/`\n- Write `.verified` marker\n\n**Acceptance criteria**:\n- Full download → verify → install flow works\n- Partial download resumes correctly\n- Corrupt download detected and retried\n- State transitions are correct\n- No network calls without explicit consent\n\n---\n\n### Layer 4: Search Integration\n\n#### hyb.search\n**Type**: task | **Priority**: P1 | **Depends on**: sem.vec.ops, sem.vec.filt\n\n**Purpose**: Implement semantic search execution and SearchMode enum.\n\n**SearchMode enum**:\n```rust\n#[derive(Clone, Copy, Debug, Default)]\npub enum SearchMode {\n    #[default]\n    Lexical,\n    Semantic,\n    Hybrid,\n}\n\nimpl SearchMode {\n    pub fn next(self) -> Self {\n        match self {\n            Lexical => Semantic,\n            Semantic => Hybrid,\n            Hybrid => Lexical,\n        }\n    }\n}\n```\n\n**Semantic search flow**:\n1. Canonicalize query text\n2. Embed query (ML or hash)\n3. Build SemanticFilter from current SearchFilters\n4. Search vector index with filter\n5. Map MessageID results back to full hits via SQLite\n\n**Query cache**:\n```rust\npub struct QueryCache {\n    embeddings: LruCache<String, Vec<f32>>,  // query → embedding\n}\n```\n- Cache key: canonical query text\n- Cache size: 100 queries (configurable)\n- Invalidate on embedder change\n\n**Acceptance criteria**:\n- `search_semantic()` returns ranked results\n- Filters are honored (agent/workspace/source/time)\n- Query cache reduces latency on repeated queries\n- Graceful error if semantic unavailable\n\n---\n\n#### hyb.rrf\n**Type**: task | **Priority**: P1 | **Depends on**: hyb.search\n\n**Purpose**: Implement Reciprocal Rank Fusion for hybrid search.\n\n**RRF formula**: `score(d) = Σ 1/(k + rank(d))` where k=60\n\n**Implementation**:\n```rust\nconst RRF_K: f32 = 60.0;\n\npub fn rrf_fuse(\n    lexical: &[SearchHit],\n    semantic: &[VectorSearchResult],\n    limit: usize,\n) -> Vec<HybridSearchHit> {\n    let mut scores: HashMap<u64, HybridScore> = HashMap::new();  // MessageID → score\n\n    for (rank, hit) in lexical.iter().enumerate() {\n        let entry = scores.entry(hit.message_id).or_default();\n        entry.rrf += 1.0 / (RRF_K + rank as f32 + 1.0);\n        entry.lexical_rank = Some(rank);\n    }\n\n    for (rank, hit) in semantic.iter().enumerate() {\n        let entry = scores.entry(hit.message_id).or_default();\n        entry.rrf += 1.0 / (RRF_K + rank as f32 + 1.0);\n        entry.semantic_rank = Some(rank);\n    }\n\n    // Sort by RRF score descending\n    let mut results: Vec<_> = scores.into_iter().collect();\n    results.sort_by(|a, b| b.1.rrf.partial_cmp(&a.1.rrf).unwrap());\n    results.truncate(limit);\n    // ... convert to HybridSearchHit\n}\n```\n\n**Candidate depth**: Fetch 3× limit from each source for better fusion.\n\n**Acceptance criteria**:\n- Documents appearing in both lists get higher scores\n- Rankings are stable (deterministic)\n- Handles disjoint result sets gracefully\n- Performance: <5ms for 500 candidates\n\n---\n\n#### hyb.rank\n**Type**: task | **Priority**: P2 | **Depends on**: hyb.rrf\n\n**Purpose**: Apply RankingMode (Recent/Balanced/Relevance) in semantic/hybrid modes.\n\n**Background**: Users expect F12 (RankingMode) to work across all search modes.\n\n**Semantic mode ranking**:\n- Map similarity [-1, 1] to [0, 1]: `sim01 = (sim + 1) / 2`\n- Apply RankingMode weights:\n  - Recent Heavy: `0.3 * sim01 + 0.7 * recency`\n  - Balanced: `0.5 * sim01 + 0.5 * recency`\n  - Relevance Heavy: `0.8 * sim01 + 0.2 * recency`\n  - Match Quality: `0.85 * sim01 + 0.15 * recency`\n  - Date Newest/Oldest: Sort by date, ignore sim\n\n**Hybrid mode ranking**:\n- Primary: RRF score\n- Tie-break: RankingMode preference\n- Tie-break 2: Higher max(lexical_bm25, semantic_sim)\n\n**Acceptance criteria**:\n- All RankingMode values work in Semantic mode\n- All RankingMode values work in Hybrid mode\n- Rankings match user expectations\n- No regression in Lexical mode\n\n---\n\n#### hyb.filt\n**Type**: task | **Priority**: P2 | **Depends on**: hyb.search\n\n**Purpose**: Ensure filter parity between Lexical and Semantic/Hybrid.\n\n**This is validation + edge case handling, not new functionality.**\n\n**Validation checklist**:\n- [ ] F10 (agent filter) works in Semantic\n- [ ] F10 works in Hybrid\n- [ ] Workspace filter (--workspace) works\n- [ ] Source filter (--source) works\n- [ ] Time filter (F6/F7) works\n- [ ] Combined filters work\n- [ ] \"All\" filter resets correctly\n\n**Edge cases**:\n- Agent with no indexed messages → empty results (not error)\n- Time range outside indexed range → empty results\n- Filter changes mid-session → re-search works\n\n**Acceptance criteria**:\n- All filter combinations tested\n- No crashes or panics on edge cases\n- Results are correct (verified against lexical)\n\n---\n\n### Layer 5: User Interface\n\n#### tui.sem.mode\n**Type**: task | **Priority**: P1 | **Depends on**: hyb.search\n\n**Purpose**:

and model not installed:\n  - Show install prompt (see tui.sem.prompt)\n  - Don't change mode until consent given\n- If model is downloading:\n  - Show toast \"Model downloading...\"\n  - Stay on current mode\n\n**Status bar indicator**:\n- `LEX` - default color\n- `SEM` - cyan (ML active)\n- `SEM*` - cyan with asterisk (hash fallback)\n- `HYB` - magenta\n\n**State persistence**:\n- Save search_mode to config\n- Restore on startup\n\n**Acceptance criteria**:\n- Alt+S cycles modes\n- Status bar updates correctly\n- Mode persists across sessions\n- Help screen (F1) documents Alt+S\n\n---\n\n#### tui.sem.state\n**Type**: task | **Priority**: P1 | **Depends on**: tui.sem.mode, sem.mod.core\n\n**Purpose**: Track SemanticAvailability state in TUI.\n\n**State

model → NotInstalled or Ready\n- User presses Alt+S to SEM → NeedsConsent (if NotInstalled)\n- User presses D → Downloading\n- Download completes → Ready\n- User presses H → HashFallback\n\n**Integration with model_manager**:\n- Subscribe to ModelState changes\n- Update SemanticAvailability accordingly\n- Handle async state updates\n\n**Acceptance criteria**:\n- State is always accurate\n- UI reflects current state\n- No race conditions on state changes\n\n---\n\n#### tui.sem.prompt\n**Type**: task | **Priority**: P1 | **Depends on**: tui.sem.state\n\n**Purpose**:

    "content": "# Suggested Improvements to `cass` (based on cass-memory-system / CMS)\n\nLast updated: 2025-12-15\n\nThis document proposes a **cass-side** implementation plan for features that CMS needs (and that are generally useful for cass users), with a special focus on:\n\n- **Remote session/log ingestion** via SSH (using existing SSH configs/keys).\n- **Strong provenance/origin metadata** stored in first-class fields (not just “it’s in the path”).\n- **Filtering** by origin/source/host in both CLI + TUI + robot outputs.\n- **Visual distinction** for remote-origin records (e.g., “same agent color, darker shade”).\n\nThe intent is to push the “remote logs + provenance + filtering + UI distinction” capability **down into cass** where it naturally belongs, so CMS can remain simpler and consume cass as a canonical “agent history search layer”.\n\nNote: this also aligns with `README.md` “Roadmap & Future Directions” → “Collaborative Features: Optional encrypted sync between machines”. The plan below focuses on a pragmatic “SSH mirror + provenance” first step (encrypted in transit); if we later want stronger guarantees, we can add optional at-rest encryption for remote caches and/or export/import bundles.\n\n---\n\n## 1) Current cass architecture (relevant to this plan)\n\nKey modules (as of today):\n\n- **Connectors** (discover + parse native agent logs): `src/connectors/*.rs`, traits/types in `src/connectors/mod.rs`.\n  - Connectors output `NormalizedConversation` + `NormalizedMessage` (+ snippets).\n- **Indexer** (orchestrates scans, persists, builds search index): `src/indexer/mod.rs`.\n  - Writes normalized data to SQLite via `src/storage/sqlite.rs`.\n  - Writes searchable docs to Tantivy via `src/search/tantivy.rs`.\n- **Search** (query parsing + filtering + ranking + caching): `src/search/query.rs` (primary), Tantivy schema in `src/search/tantivy.rs`.\n  - Result type used everywhere: `SearchHit` in `src/search/query.rs`.\n- **TUI** (render panes, filters, detail view): `src/ui/tui.rs` and `src/ui/components/theme.rs`.\n  - Filter state: `SearchFilters` in `src/search/query.rs`.\n  - Detail loading: `src/ui/data.rs` reads from SQLite (`SqliteStorage`) by `source_path`.\n\nImportant existing constraints/assumptions that matter for remote ingestion:\n\n- Tantivy schema fields are currently: `agent`, `workspace`, `source_path`, `msg_idx`, `created_at`, `title`, `content`, `preview`, etc. (`src/search/tantivy.rs`).\n- SQLite `conversations` uniqueness is currently `UNIQUE(agent_id, external_id)` (`src/storage/sqlite.rs`).\n- Indexer currently passes `ScanContext { data_root: data_dir, since_ts }` to all connectors (`src/indexer/mod.rs`).\n- Search filters currently include only: agents, workspaces, created_from/to (`SearchFilters` in `src/search/query.rs`).\n- TUI pane theme is derived from agent slug (`ThemePalette::agent_pane` in `src/ui/components/theme.rs`) and used for result list rendering (`src/ui/tui.rs`).\n\n---\n\n## 2) The CMS-driven feature request (what “good” looks like)\n\nFrom the CMS planning work, plus the explicit request here:\n\n1) **Pull logs from other machines**\n   - Use SSH configs/keys (ideally: reuse `~/.ssh/config` host aliases).\n   - Pull remote agent logs into the local cass data dir (or a sibling cache root).\n\n2) **Remote logs must be “separate”**\n   - Stored with provenance fields so results can be filtered by:\n     - local vs remote (origin kind)\n     - source id (user-friendly stable id)\n     - host / machine identifier (for display and auditing)\n   - Not just a path prefix hack; provenance should be queryable.\n\n3) **Remote logs must look visually distinct**\n   - Same base agent color identity, but a darker / dimmer variant for remote-origin entries.\n   - Also add an explicit badge (e.g., `[work-laptop]`) so distinction is obvious even in monochrome terminals.\n\n4) **Robot outputs must include provenance**\n   - CMS and other automation should be able to parse origin/source metadata reliably.\n\n---\n\n## 3) Biggest correctness blockers to remote ingestion (fix first)\n\nThese are “make remote possible without breaking correctness” prerequisites.\n\n### 3.1 Conversation identity collisions across sources\n\nSQLite uniqueness currently depends on `(agent_id, external_id)` (`src/storage/sqlite.rs`).\n\nOnce we ingest multiple machines, **external_id WILL collide** across sources (especially for connectors that use simple ids or filenames, or for agents that generate ids with low entropy).\n\nExample risk:\n- `aider` currently sets `external_id` to the filename `.aider.chat.history.md` (`src/connectors/aider.rs`), which is trivially collision-prone even on a single machine.\n\nPlan requirement:\n- Conversation identity must incorporate **provenance** so “same agent + same external id” on different sources becomes “distinct conversations”.\n\n### 3.2 Indexer “scan roots” vs “data dir” confusion (impacts remote + local)\n\nIndexer sets `ScanContext.data_root = opts.data_dir` (`src/indexer/mod.rs`), but several connectors interpret `data_root` as a scan root (e.g., Aider scans under `data_root`).\n\nRemote ingestion increases the need for:\n- multiple scan roots (local default roots + remote mirror roots)\n- per-root provenance\n\nSo we should formalize:\n- `data_dir` (cass internal state) vs\n- `scan_roots` (where logs are read from)\n\nThis is the right place to solve remote ingestion cleanly.\n\n---\n\n## 4) Proposal: first-class “Sources / Origins” in cass\n\n### 4.1 Data model\n\nAdd a conceptual model:\n\n- **Source**: “where this session came from”\n  - `source_id` (stable, user-friendly): e.g. `local`, `work-laptop`, `home-server`\n  - `kind`: `local` | `ssh` (later: `s3`, `git`, etc)\n  - `host_label`: string to show in UI (often SSH alias or hostname)\n  - optional: `machine_id` (stable id; hashed if desired)\n  - optional: workspace path rewrite rules (see 4.4)\n\n- **Origin** (per conversation/message doc):\n  - `origin_source_id` (required)\n  - `origin_kind` (required)\n  - `origin_host` (optional, for display)\n\n### 4.2 Storage representation (SQLite)\n\nPreferred “proper” approach:\n\n1) Add `sources` table (new)\n   - `id TEXT PRIMARY KEY` (use `source_id`)\n   - `kind TEXT NOT NULL`\n   - `host_label TEXT`\n   - `machine_id TEXT`\n   - `created_at INTEGER`, `updated_at INTEGER`\n   - `config_json TEXT` (for ssh params, path rewrite rules, etc)\n\n2) Add provenance columns on `conversations` (new columns)\n   - `source_id TEXT NOT NULL REFERENCES sources(id)` (default `local`)\n   - `origin_host TEXT` (nullable, display)\n\n3) Update uniqueness\n   - New uniqueness should include `source_id`:\n     - `UNIQUE(source_id, agent_id, external_id)`\n\nThis requires a migration that rewrites the conversations table (SQLite can’t easily alter unique constraints in place). This migration should be done via:\n- create new table + copy + rewire foreign keys + drop/rename old table.\n\n### 4.3 Search representation (Tantivy)\n\nAdd new Tantivy fields in `src/search/tantivy.rs`:\n- `source_id` (STRING | STORED)  — filterable\n- `origin_kind` (STRING | STORED) — filterable (if not derivable from source)\n- optional `origin_host` (STRING | STORED) — filterable/display\n\nIndexing:\n- when `TantivyIndex::add_messages` builds each doc, add these fields per message doc.\n\nQuerying:\n- extend `SearchFilters` (in `src/search/query.rs`) with:\n  - `sources: HashSet<String>` (source_id)\n  - optionally `origin_kinds: HashSet<String>` (or just source-based)\n  - optionally `hosts: HashSet<String>`\n- update `search_tantivy` and `search_sqlite` to apply these filters as `TermQuery` (tantivy) / `IN (...)` (sqlite backend).\n\n### 4.4 Workspace path rewriting (high leverage for multi-machine)\n\nProblem: remote sessions carry remote absolute workspace paths; filters and grouping become painful.\n\nAdd optional per-source rewrite rules:\n- e.g. `/home/jemanuel/projects` → `/Users/jemanuel/projects`\n\nImplementation idea:\n- store rewrite rules in `sources.config_json`\n- during normalization (ingest-time), rewrite `NormalizedConversation.workspace` for that source.\n\nThis makes:\n- workspace filters stable across machines\n- TUI display consistent\n- potential future feature: “open workspace locally” more reliable\n\n---\n\n## 5) Proposal: Remote source ingestion via SSH (mirror into data dir)\n\n### 5.1 Principle: mirror raw logs locally (so `cass view` keeps working)\n\nBecause `cass view` currently reads files by `source_path` (`run_view` in `src/lib.rs`), the simplest UX is:\n\n- Remote logs are synced to local disk (under cass data dir).\n- Indexing uses those local mirror files, so `source_path` exists locally.\n\n### 5.2 Local mirror layout\n\nUnder the cass data dir (see `default_data_dir()` in `src/lib.rs` and `index_dir()` in `src/search/tantivy.rs`):\n\n`<data_dir>/remotes/<source_id>/mirror/...`\n\nWithin `mirror/`, preserve a structure that makes it easy to:\n- understand provenance\n- scan multiple agent roots\n- avoid collisions between different remote machines\n\nExample (macOS remote):\n\n- `<data_dir>/remotes/work-laptop/mirror/home/.codex/sessions/...`\n- `<data_dir>/remotes/work-laptop/mirror/home/.claude/projects/...`\n- `<data_dir>/remotes/work-laptop/mirror/home/.gemini/tmp/...`\n- `<data_dir>/remotes/work-laptop/mirror/home/.pi/agent/sessions/...`\n- `<data_dir>/remotes/work-laptop/mirror/Library/Application Support/Cursor/User/...` (mac)\n- `<data_dir>/remotes/work-laptop/mirror/Library/Application Support/com.openai.chat/...` (mac)\n\nFor linux remotes, mirror linux paths (home-based; no Library/ support).\n\n### 5.3 Sync engine\n\nAdd a new CLI family, for example:\n\n- `cass sources add ssh <source_id> --host <ssh-alias> --platform macos|linux`\n- `cass sources sync [--source <id>] [--all]`\n- `cass sources list --json`\n- `cass sources doctor --json` (validate ssh connectivity + paths)\n\nImplementation options for transport:\n\nOption A (pragmatic, leverages SSH config best): shell out to `rsync` over `ssh`\n- Pros: fastest, incremental, uses existing SSH config/keys/jumps, handles mtimes well.\n- Cons: external dependency; Windows may not have rsync.\n\nOption B (portable, pure Rust): SFTP via `ssh2` / `russh`\n- Pros: no external command dependency.\n- Cons: more work; performance less great; parsing SSH config harder.\n\nRecommended plan:\n- Prefer rsync when available; fall back to SFTP when not.\n- Never use rsync `--delete` by default (avoid accidental deletion semantics).\n- Persist sync status and “last successful sync time” per source.\n\n### 5.4 Mapping “remote default paths” per platform\n\nRemote sessions live in different default locations depending on OS. We need a way to decide which remote paths to sync.\n\nRecommended approach:\n- Each `Source` has `platform` and an explicit list of remote paths to sync.\n- Provide sensible presets:\n  - `cass sources add ssh work-laptop --host work-laptop --preset macos-defaults`\n  - `cass sources add ssh home-server --host home-server --preset linux-defaults`\n\nWhere presets include the known agent roots documented in `README.md` (Codex, Claude Code, etc).\n\n---\n\n## 6) Indexing pipeline changes required\n\n### 6.1 Make “scan roots” explicit in the indexer\n\nToday, the indexer passes `ScanContext { data_root: data_dir, ... }` to all connectors (`src/indexer/mod.rs`).\n\nFor remote ingestion we should:\n- construct a list of scan roots:\n  - local roots (existing `watch_roots()` in `src/indexer/mod.rs` is a good starting point)\n  - plus remote mirror roots per source\n- pass (root, source_id, origin_kind, host_label, rewrite rules) to the connector scan pass\n\nTwo viable implementation strategies:\n\n1) Minimal refactor: “scan per root”\n   - For each connector, for each scan root relevant to that connector, call `connector.scan(&ScanContext { data_root: root, since_ts })`\n   - After `scan()`, inject provenance into `NormalizedConversation.metadata` before persistence/indexing.\n   - Pros: smaller change footprint.\n   - Cons: connectors’ “data_root override heuristics” are inconsistent today; requires some per-connector tweaks anyway.\n\n2) Cleaner refactor: extend `ScanContext` to carry:\n   - `data_dir` (internal state root)\n   - `scan_roots: Vec<ScanRoot>` where `ScanRoot` carries provenance\n   - Each connector decides which roots it cares about.\n   - Pros: scales better; avoids repeated connector instantiation.\n   - Cons: larger API change (but project is alpha; worth it).\n\nRecommendation: do (2) if we’re serious about remote + correctness.\n\n### 6.2 Provenance injection point\n\nRegardless of approach, ensure provenance is set in one place (indexer) so connectors stay simpler.\n\nSuggested reserved metadata namespace:\n\n`metadata[\"cass\"][\"origin\"] = { \"source_id\": \"...\", \"kind\": \"...\", \"host\": \"...\" }`\n\nThen:\n- SQLite persistence stores these fields into new columns (or into metadata_json during a transitional phase).\n- Tantivy indexing extracts these fields into first-class index fields.\n- TUI can display from `SearchHit` directly (preferred) or fallback to metadata in detail view.\n\n### 6.3 Fix conversation identity stability across sources\n\nPick one (or both) of these:\n\n- **Proper schema fix** (preferred): uniqueness includes `source_id`.\n- **Transitional fallback**: prefix `external_id` with `source_id` at ingest time (still store the original external id in metadata).\n\nEven if you do the “proper” schema fix, prefixing can still be useful for human debugging (but it’s optional).\n\n### 6.4 Deduplication should not erase origin distinctions\n\nSearch dedup currently keys only on normalized content (`deduplicate_hits` in `src/search/query.rs`).\n\nFor remote support, consider changing the dedup key to:\n- `(normalized_content, source_id)` or\n- allow duplicates across sources while still deduping within a source.\n\nOtherwise a “best hit” from one source could hide the corresponding hit from another, undermining the “remote logs are distinct” principle.\n\n---\n\n## 7) Search + CLI + robot-output changes\n\n### 7.1 CLI flags\n\nAdd filters parallel to existing `--agent` and `--workspace`:\n\n- `cass search ... --source <id>` (repeatable)\n- `cass search ... --origin local|ssh` (optional; or derive via source)\n- `cass search ... --host <label>` (repeatable; optional)\n\nAlso update:\n- `cass timeline` to accept `--source` and `--host`\n- `cass stats` to optionally group by source\n\n### 7.2 Robot output fields\n\nExtend `SearchHit` (`src/search/query.rs`) with optional fields:\n- `source_id: Option<String>`\n- `origin_kind: Option<String>`\n- `origin_host: Option<String>`\n\nThen update:\n- `output_robot_results` known field list in `src/lib.rs`\n- `cass robot-docs schemas` and `cass introspect --json` schema output to document the new fields.\n\nMaintain backwards compatibility by making new fields optional and absent when not available.\n\n---\n\n## 8) TUI changes (visual distinction + filtering)\n\n### 8.1 Visual distinction (“darker shade of same base color”)\n\nIn the results list render path (`src/ui/tui.rs`), each hit currently uses `ThemePalette::agent_pane(&pane.agent)` to get `bg/fg/accent`.\n\nImplement per-hit styling variant:\n\n- If `hit.source_id != \"local\"` (or `origin_kind == \"ssh\"`):\n  - Dim the accent: use existing `dim_color()` in `src/ui/tui.rs` (or blend with `lerp_color()` toward background).\n  - Optionally dim the row stripe background slightly more for remote hits.\n  - Add a badge in the “location” line, e.g.:\n    - `[src:work-laptop]` or `[remote:work-laptop]`\n\nThis gives both:\n- color-based distinction (darker shade)\n- explicit text label (works without color)\n\n### 8.2 Filtering UI\n\nExtend `SearchFilters` to include `sources` and update:\n- filter chips (`chips_for_filters` in `src/ui/tui.rs`)\n- saved views persistence (saved view struct in `src/ui/tui.rs`)\n- new input mode and shortcut (suggest: F11 for “source filter” to keep F3/F4 pattern)\n\n---\n\n## 9) Testing & migration plan\n\n### 9.0 Strong recommendation for existing users: treat search DB + index as rebuildable caches\n\nGiven there are existing users, the safest user experience is:\n\n- **Never break startup/search** due to schema drift.\n- Prefer **automatic rebuild** of *derived* artifacts (Tantivy index + the main “normalized conversations” SQLite DB) when the schema changes in incompatible ways.\n- Preserve truly user-authored state separately (already true today for bookmarks: `src/bookmarks.rs` uses a separate `bookmarks.db`; and UI preferences live in `tui_state.json`).\n\nThis makes upgrades reliable: we don’t need brittle SQLite table-rewrite migrations for data we can re-derive by rescanning the original agent logs.\n\n### 9.1 SQLite migration safety\n\nFor the “rebuildable cache” approach, the plan is:\n\n- Still bump `SCHEMA_VERSION` in `src/storage/sqlite.rs` to document expected schema.\n- If `migrate()` encounters an **unsupported** or **incompatible** schema version, do **not** error-out for users.\n  - Instead: move the existing DB out of the way (e.g., rename to `agent_search.db.bak-<timestamp>`), create a fresh DB, and trigger/require a full reindex.\n  - Optionally keep only a single backup (or keep indefinitely; deletion policy is a product decision).\n\nIf we decide we *do* want to preserve some DB-resident non-derived state in the future, then we should:\n\n- Keep that state in a separate DB/table namespace (like bookmarks already do), so the main search DB remains safely rebuildable.\n\nInclude tests to validate:\n- existing DB upgrades cleanly\n- no data loss across migration\n- uniqueness behaves as expected\n\n### 9.2 Tantivy schema bump\n\nUpdate `src/search/tantivy.rs`:\n- add `source_id` / `origin_kind` / `origin_host` fields\n- bump `SCHEMA_HASH` so rebuild triggers correctly\n- strongly consider bumping Tantivy `SCHEMA_VERSION` (directory name) as well, so old indexes can remain side-by-side for easy rollback/debug\n\n### 9.3 Connector + indexer integration tests\n\nAdd tests that simulate:\n- local + remote mirrors producing same `external_id`\n- verify they do not merge incorrectly\n- verify search filters by `source_id` work\n\n---\n\n## 10) Suggested execution plan (dependency-ordered)\n\nThis is written in “bead-like” task granularity; you can translate to actual `bd create` later if desired.\n\n1) **Define provenance model**\n   - Add `Source`/`Origin` structs and decide canonical field names for robot outputs.\n\n2) **Add source storage**\n   - SQLite: `sources` table + `conversations.source_id` + updated uniqueness.\n   - Tantivy: add `source_id`/`origin_kind`/`origin_host` fields.\n\n3) **Plumb provenance into indexing**\n   - Indexer injects provenance into each `NormalizedConversation` (or equivalent).\n   - Ensure collisions cannot merge across sources.\n\n4) **CLI + robot output updates**\n   - Add `--source` / `--host` flags.\n   - Update robot schemas/docs/introspect.\n\n5) **TUI distinction + filter**\n   - Add badge + dim color variant for remote hits.\n   - Add source filter chip and input mode + shortcuts.\n\n6) **Remote sources config + sync**\n   - Create a config file in data dir (or reuse `.env` only for dev).\n   - Implement `cass sources add/list/sync/doctor`.\n   - Implement rsync-first sync engine with safe defaults (no delete).\n\n7) **Workspace rewrite rules (optional but high value)**\n   - Implement per-source path mapping.\n\n8) **Tests + fixture coverage**\n   - Add regression tests covering collisions, filters, and UI formatting decisions.\n\n---\n\n## 11) Notes for CMS integration\n\nIf cass implements the above:\n\n- CMS can treat cass as the canonical “search over all agent history (including remote)” layer.\n- CMS can rely on stable fields in robot output:\n  - `agent`, `source_path`, `line_number`, plus new `source_id` / `origin_kind` / `origin_host`.\n- CMS “remote logs” UI can match cass semantics:\n  - same base agent color, darker variant when `origin_kind != local`.\n\nThis reduces duplication: CMS doesn’t need to re-implement SSH sync or provenance modeling unless it has additional needs beyond search/history.\n"

    "content": "# Testing Guide\n\n> Guidelines for testing in the cass (Coding Agent Session Search) codebase.\n\n---\n\n## No-Mock Policy\n\n### Philosophy\n\nThis project adheres to a **strict no-mock policy** for testing. Instead of mocking external dependencies, we use:\n\n1. **Real implementations** with test configurations\n2. **Fixture data** from actual sessions and real scenarios\n3. **Integration test harnesses** that exercise real code paths\n4. **E2E tests** that validate complete workflows\n\n### Why No Mocks?\n\nMocks are problematic because they:\n\n- **Hide bugs**: Mocks don't catch when real implementations change behavior\n- **Create maintenance burden**: Mock implementations drift from reality\n- **Reduce confidence**: Passing tests don't prove the real system works\n- **Encourage poor design**: Mocks make it easy to test tightly-coupled code\n\n### What We Use Instead\n\n| Instead of... | Use... |\n|---------------|--------|\n| Mock connectors | Real session fixtures in `tests/fixtures/connectors/` |\n| Mock databases | Real SQLite with test data |\n| Mock Tantivy | Real index with small fixture corpus |\n| Mock embedders | Hash embedder (fast, deterministic) |\n| Mock daemon | Channel-based test harness |\n| Mock filesystem | Tempdir with real fixture files |\n\n### Allowlist: True Boundaries\n\nSome scenarios require deterministic fixture constructors. These are explicitly\nallowlisted (see `test-results/no_mock_allowlist.json`):\n\n1. **Fixture constructors** (`#[cfg(test)]` only):\n   - `mock_system_info` in `src/sources/install.rs` - deterministic SystemInfo for pure logic tests\n   - `mock_resources` in `src/sources/install.rs` - deterministic ResourceInfo for pure logic tests\n\n### CI Enforcement\n\nThe CI pipeline enforces the no-mock policy:\n\n```bash\n# Run the no-mock check\n./scripts/validate_ci.sh --no-mock-only\n\n# Skip locally (for development iteration)\nSKIP_NO_MOCK_CHECK=1 ./scripts/validate_ci.sh\n```\n\nThe check:\n1. Searches for `Mock*`, `Fake*`, `Stub*`, `mock_`, `fake_`, `stub_` patterns\n2. Compares against the allowlist in `test-results/no_mock_allowlist.json`\n3. Fails if unapproved patterns are found\n\n### Requesting an Allowlist Exception\n\nTo request a new allowlist entry:\n\n1. Create a bead explaining why a real implementation is impossible\n2. Add an entry to `test-results/no_mock_allowlist.json`:\n   ```json\n   {\n     \"path\": \"src/your/file.rs\",\n     \"pattern\": \"MockThing\",\n     \"rationale\": \"Why real implementation is impossible\",\n     \"owner\": \"your-team\",\n     \"review_date\": \"YYYY-MM-DD (max 6 months)\",\n     \"downstream_task\": \"bd-xxxx (to remove this entry)\",\n     \"cfg_test_only\": true\n   }\n   ```\n3. Get approval via code review\n4. Entries expire after 6 months and require re-justification\n\n---\n\n## Test Structure\n\n### Unit Tests (`#[cfg(test)]` modules)\n\nIn-file unit tests for isolated function/trait behavior:\n\n```rust\n#[cfg(test)]\nmod tests {\n    use super::*;\n\n    #[test]\n    fn test_parse_message() {\n        // Test with real JSONL content, not mocked data\n        let content = include_str!(\"../tests/fixtures/messages/sample.jsonl\");\n        let result = parse_message(content);\n        assert!(result.is_ok());\n    }\n}\n```\n\n### Integration Tests (`tests/`)\n\nTests that exercise multiple components together:\n\n- `tests/connector_*.rs` - Connector parsing with fixture files\n- `tests/search_*.rs` - Search pipeline with real indexes\n- `tests/semantic_*.rs` - Embedding with hash embedder\n- `tests/daemon_client_integration.rs` - Daemon client with channel harness\n\n### E2E Tests\n\n**Rust E2E** (`tests/e2e_*.rs`):\n- Full CLI invocation tests\n- Real fixtures, real binaries, real outputs\n\n**Browser E2E** (`tests/e2e/`):\n- Playwright tests for HTML exports\n- Run on CI only (see AGENTS.md \"E2E Browser Tests\")\n\n**Shell E2E** (`scripts/e2e/*.sh`):\n- `connector_stress.sh` - Stress-test connector parsing with malformed/edge fixtures\n- `query_parser_e2e.sh` - Exercise query parsing end-to-end via CLI search flows\n- `security_paths_e2e.sh` - Validate export path security and traversal hardening\n- `full_coverage_validation.sh` - Master runner (executes the scripts above, runs key Rust E2E suites, validates JSONL, and produces coverage + summary)\n- All shell scripts must source `scripts/lib/e2e_log.sh` and emit JSONL to `test-results/e2e/`\n\n#### Scenario Coverage (T4.*)\n\nThe following scenario-focused E2E suites are complete and tracked:\n\n- Error recovery: `tests/e2e_error_recovery.rs`\n- Large datasets: `tests/e2e_large_dataset.rs`\n- Mobile devices: `tests/e2e/mobile/*.spec.ts`\n- Offline mode: `tests/e2e/offline/*.spec.ts`\n- Accessibility: `tests/e2e/accessibility/*.spec.ts`\n\n---\n\n## Fixtures\n\n### Location\n\nAll fixture data lives under `tests/fixtures/`:\n\n```\ntests/fixtures/\n├── connectors/           # Real session files per agent\n│   ├── claude/\n│   ├── codex/\n│   ├── cursor/\n│   └── ...\n├── html_export/          # Real exported sessions\n│   └── real_sessions/\n├── messages/             # Sample JSONL messages\n├── models/               # Small valid ONNX models (if needed)\n└── sources/              # Multi-machine sync fixtures\n```\n\n### Creating Fixtures\n\n1. Use real data from actual agent sessions\n2. Anonymize sensitive content (usernames, paths, secrets)\n3. Keep fixtures small but representative\n4. Document the fixture's purpose in a README\n\n### Fixture Helpers Module\n\nUse `tests/fixture_helpers.rs` for setting up connector tests:\n\n```rust\nuse crate::fixture_helpers::{setup_connector_test, create_project_dir, write_session_file};\n\n#[test]\nfn test_my_connector() {\n    // Creates temp dir with \"fixture-{agent}\" naming\n    let (dir, data_dir) = setup_connector_test(\"claude\");\n\n    // Create project structure\n    let project_dir = create_project_dir(&data_dir, \"my-project\");\n    write_session_file(&project_dir, \"session.jsonl\", &content);\n\n    // ... run connector tests ...\n}\n```\n\n**Important**: Use `fixture-{agent}` naming (not `mock-{agent}`) for temp directories.\n\n### Fixture Provenance (MANIFEST.json)\n\nAll connector fixtures are tracked in `tests/fixtures/connectors/MANIFEST.json`:\n\n```json\n{\n  \"fixtures\": {\n    \"claude\": {\n      \"source\": \"tests/fixtures/claude_code_real\",\n      \"capture_date\": \"2025-11-25\",\n      \"redaction_policy\": \"usernames_anonymized\",\n      \"files\": [\n        {\n          \"path\": \"projects/-test-project/agent-test123.jsonl\",\n          \"sha256\": \"89dd0a299dd4e761d185a65b652d6a29982cbc71aa9e07cfa3aa07475696c202\"\n        }\n      ]\n    }\n  }\n}\n```\n\nWhen adding new fixtures:\n1. Add an entry to the MANIFEST.json\n2. Compute SHA256 hash: `sha256sum <file>`\n3. Document the capture date and redaction policy\n\n### Loading Fixtures in Tests\n\n```rust\n// Good: Load real fixture\nlet fixture = include_str!(\"fixtures/connectors/claude/session.jsonl\");\n\n// Bad: Create mock data inline\nlet mock_session = r#\"{\"fake\": \"data\"}\"#;  // NO!\n```\n\n### Model Fixtures for Semantic Search\n\nFor tests that require embedding models (semantic search, reranking), use the real\nmodel fixtures in `tests/fixtures/models/`:\n\n```\ntests/fixtures/models/\n├── xenova-paraphrase-minilm-l3-v2-int8/   # Embedding model (~17 MB)\n│   ├── model.onnx\n│   ├── tokenizer.json\n│   ├── config.json\n│   └── checksums.sha256\n├── xenova-ms-marco-minilm-l6-v2-int8/     # Reranker model (~22 MB)\n│   ├── model.onnx\n│   ├── tokenizer.json\n│   └── checksums.sha256\n└── README.md\n```\n\n**Usage in tests:**\n\n```rust\nuse crate::fixture_helpers::{embedder_fixture_dir, reranker_fixture_dir};\n\n#[test]\nfn test_semantic_search() {\n    // Get fixture directories with real ONNX models\n    let embedder_dir = embedder_fixture_dir();\n    let reranker_dir = reranker_fixture_dir();\n\n    // Verify checksums before loading\n    verify_model_fixture_checksums(&embedder_dir).expect(\"valid checksums\");\n\n    // Now load and use the real model\n    // ...\n}\n```\n\n**Model sources:**\n- Embedding: `Xenova/paraphrase-MiniLM-L3-v2` (Apache-2.0)\n- Reranker: `Xenova/ms-marco-MiniLM-L-6-v2` (Apache-2.0)\n\n### SSH Test Fixtures\n\nSSH-related tests use Docker containers with a real SSH server:\n\n**Docker infrastructure:**\n```\ntests/docker/\n├── Dockerfile.sshd    # SSH server image\n└── entrypoint.sh      # Container startup script\n```\n\n**Probe fixtures:** `tests/fixtures/sources/probe/`\n- `indexed_host.json` - Host with cass indexed (847 sessions)\n- `not_indexed_host.json` - Host with cass but not indexed\n- `no_cass_host.json` - Host without cass installed\n- `unreachable_host.json` - Connection failure scenario\n\n**Usage:**\n\n```rust\nuse crate::ssh_test_helper::SshTestServer;\n\n#[test]\n#[ignore = \"requires Docker\"]\nfn test_ssh_sync() {\n    // Start ephemeral SSH server with auto-generated keys\n    let server = SshTestServer::start().expect(\"SSH server should start\");\n\n    // Use server.ssh_target() for connections\n    let target = server.ssh_target();\n    // ... run SSH-based tests ...\n\n    // Container auto-cleaned on drop\n}\n```\n\n**Running SSH tests:**\n```bash\n# Build SSH test image first\ndocker build -t cass-ssh-test:latest -f tests/docker/Dockerfile.sshd tests/docker/\n\n# Run ignored tests (requires Docker)\ncargo test -- --ignored\n```\n\n### PTY-Based TUI Testing\n\nTUI tests support two modes:\n\n1. **Headless mode** (`--once` + `TUI_HEADLESS=1`):\n   - Non-interactive, exits immediately after init\n   - Validates launch, exit codes, no panics\n   - Used in `tests/tui_smoke.rs`, `tests/tui_headless_smoke.rs`\n\n2. **Flow simulation** (via CLI equivalents):\n   - Search/filter/export flows simulated via CLI commands\n   - Results compared against TUI behavior expectations\n   - Artifacts captured under `test-results/e2e/tui/`\n   - Used in `tests/e2e_tui_smoke_flows.rs`\n\n**Example headless test:**\n```rust\ncargo_bin_cmd!(\"cass\")\n    .arg(\"tui\")\n    .arg(\"--once\")\n    .arg(\"--data-dir\")\n    .arg(&data_dir)\n    .env(\"TUI_HEADLESS\", \"1\")\n    .assert()\n    .success();\n```\n\n**Artifacts:** TUI E2E tests capture:\n- Per-step stdout/stderr\n- Search results as JSON\n- Timing metrics\n- Summary JSON with trace ID\n\nStored in: `test-results/e2e/tui/<trace_id>_*.txt`\n\n**Note:** Full PTY-based interactive testing (sending real keystrokes) would require\na PTY crate (e.g., `portable_pty`). Current tests use headless mode with CLI equivalents.\n\n---\n\n## Running Tests\n\n### Local Development\n\n```bash\n# Run all tests\ncargo test\n\n# Run specific test file\ncargo test --test connector_claude\n\n# Run with logging\nRUST_LOG=debug cargo test\n\n# Skip expensive tests\ncargo test --lib  # Unit tests only\n```\n\n### CI Pipeline\n\nThe full CI pipeline runs:\n\n```bash\n./scripts/validate_ci.sh\n```\n\nWhich includes:\n1. No-mock policy check\n2. `cargo fmt --check`\n3. `cargo clippy`\n4. `cargo test`\n5. Crypto vector tests\n6. `cargo audit` (if installed)\n\n### Browser E2E Tests\n\n**Do not run locally** - they consume significant resources.\n\nPush to a branch and let GitHub Actions run them:\n- Workflow: `.github/workflows/browser-tests.yml`\n- Runs on: Chromium, Firefox, WebKit\n- Uploads: Test artifacts and reports\n\n---\n\n## Snapshot Baseline Regeneration & Review (FrankenTUI)\n\nSnapshot baselines are a **UI contract**, not a convenience artifact. Never run blanket blesses without proving why each change is intentional.\n\n### Snapshot Suites and Ownership\n\n| Snapshot suite | Test entrypoint | Snapshot files |\n|----------------|-----------------|----------------|\n| Core ftui harness smoke baselines | `tests/ftui_harness_snapshots.rs` (`ftui_snapshot_*`) | `tests/snapshots/ftui_*.snap` / `tests/snapshots/ftui_*.ansi.snap` |\n| Cass affordance baselines | `src/ui/app.rs` (`snapshot_baseline_*`) | `tests/snapshots/cassapp_baseline_*.snap` |\n| Search-surface regressions | `src/ui/app.rs` (`snapshot_search_surface_*`) | `tests/snapshots/cassapp_search_surface_*.snap` |\n\n### Default Verification (No Regeneration)\n\nRun these first to confirm whether snapshots are stale:\n\n```bash\ncargo test snapshot_baseline_ -- --nocapture\ncargo test snapshot_search_surface_ -- --nocapture\ncargo test --test ftui_harness_snapshots -- --nocapture\n```\n\n### Targeted Regeneration (Intentional Changes Only)\n\nUse `BLESS=1` only for the suite you intentionally changed:\n\n```bash\nBLESS=1 cargo test snapshot_baseline_ -- --nocapture\nBLESS=1 cargo test snapshot_search_surface_ -- --nocapture\nBLESS=1 cargo test --test ftui_harness_snapshots -- --nocapture\n```\n\n### Mandatory Review Protocol\n\n1. Regenerate only targeted snapshots (never all suites by default).\n2. Inspect diffs directly:\n   ```bash\n   git diff -- tests/snapshots/*.snap\n   ```\n3. Validate behavior guards still pass:\n   ```bash\n   cargo test search_surface_interaction_matrix_enter_click_escape -- --nocapture\n   cargo test detail_markdown_ -- --nocapture\n   cargo test markdown_theme_ -- --nocapture\n   ```\n4. Run project quality gates:\n   ```bash\n   cargo fmt --check\n   cargo check --all-targets\n   cargo clippy --all-targets -- -D warnings\n   ```\n5. In the bead/PR note, explicitly record:\n   - Which snapshot suite was regenerated\n   - Why each changed region is intentional\n   - Which non-snapshot behavioral tests were run as guards\n\n### Snapshot Diff Heuristics for Reviewers\n\n- **Expected:** spacing, border glyph, color-role, and layout shifts that map to an intentional UI change in the bead scope.\n- **Suspicious:** missing footer/help hints, removed role gutters, vanished filter pill hierarchy, clipped text, or theme-specific parity drift (dark vs light mismatch).\n- **Reject if present:** unrelated snapshot churn outside touched feature scope, unexplained multiline reflow across untouched panes, or regressions in interaction guard tests.\n\n---\n\n## Coverage Policy\n\n### Threshold Requirements\n\n| Metric | Threshold | Enforcement |\n|--------|-----------|-------------|\n| Line coverage | **60%** minimum | Required on PR merge |\n| Target coverage | **80%** | Recommended, shown in CI summary |\n\n### CI Enforcement\n\nCoverage is enforced via `.github/workflows/coverage.yml`:\n\n- **On PRs**: Coverage below 60% **blocks merge**\n- **On main**: Coverage is reported to Codecov for tracking\n- **Summary**: Each run shows coverage status in GitHub Actions summary\n\n### Running Coverage Locally\n\n```bash\n# Install cargo-llvm-cov (requires nightly)\nrustup install nightly\ncargo +nightly install cargo-llvm-cov\n\n# Generate coverage report\ncargo +nightly llvm-cov --workspace --lib \\\n  --ignore-filename-regex \"(tests/|benches/)\"\n\n# Generate HTML report for detailed analysis\ncargo +nightly llvm-cov --workspace --lib \\\n  --ignore-filename-regex \"(tests/|benches/)\" \\\n  --html --open\n```\n\n### Coverage Exclusions\n\nThe following are excluded from coverage calculation:\n- `tests/` directory (test code itself)\n- `benches/` directory (benchmark code)\n\n### Improving Coverage\n\nWhen adding new code:\n\n1. **Write tests first** (TDD) or alongside implementation\n2. **Focus on branches**: Cover error paths, not just happy paths\n3. **Use fixtures**: Real data from `tests/fixtures/` over synthetic data\n4. **Check locally**: Run coverage before pushing to catch gaps early\n\nWhen coverage drops on a PR:\n\n1. Identify uncovered lines in the HTML report\n2. Add targeted tests for new code paths\n3. Consider if untested code is dead code (remove it)\n\n---\n\n## E2E Logging Infrastructure\n\n### Unified JSONL Schema\n\nAll E2E test infrastructure emits structured JSONL logs following a unified schema. This enables consistent log aggregation, CI integration, and debugging across all test runners.\n\n**Schema Documentation:** `test-results/e2e/SCHEMA.md`\n\n**Event Types:**\n- `run_start` - Test run begins, captures environment metadata\n- `test_start` - Individual test begins\n- `test_end` - Individual test completes (with status, duration, errors)\n- `run_end` - Test run completes with summary statistics\n- `log` - General log messages (INFO, WARN, ERROR, DEBUG)\n- `phase_start`/`phase_end` - Multi-phase run tracking\n\n**Test fields (test_start/test_end):**\n- `test.name`, `test.suite`\n- `test.test_id` (stable `${suite}::${name}`)\n- `test.trace_id` (matches CLI trace spans)\n- `test.artifact_paths` (dir/stdout/stderr/cass_log/trace)\n\n### Logger Implementations\n\n| Runner | Implementation | Output |\n|--------|---------------|--------|\n| Rust E2E | `tests/util/e2e_log.rs` | `test-results/e2e/<suite>/<test>/cass.log` |\n| Shell scripts | `scripts/lib/e2e_log.sh` | `test-results/e2e/shell_*.jsonl` |\n| Playwright | `tests/e2e/reporters/jsonl-reporter.ts` | `test-results/e2e/playwright_*.jsonl` |\n\n**Per-test artifacts (Rust E2E):**\n`test-results/e2e/<suite>/<test>/` contains:\n- `stdout` / `stderr` - Captured command output\n- `cass.log` - Structured JSONL events (SCHEMA.md)\n- `trace.jsonl` - CLI trace spans (command, args, timestamps, exit_code, trace_id)\n\nRust E2E tests set `CASS_TRACE_FILE` + `CASS_TRACE_ID` per test to ensure trace spans\nare correlated with the same `trace_id` recorded in `cass.log`.\n\n### Rust E2E Logger\n\n```rust\nuse crate::util::e2e_log::E2eLogger;\n\nlet logger = E2eLogger::new(\"my_test\", None)?;\nlogger.run_start(None)?;\n\nlogger.test_start(\"test_name\", \"suite_name\", Some(\"file.rs\"), Some(42))?;\n// ... run test ...\nlogger.test_pass(\"test_name\", \"suite_name\", duration_ms)?;\n\nlogger.run_end(total, passed, failed, skipped, duration_ms)?;\n```\n\n### Shell Script Logger\n\n```bash\nsource scripts/lib/e2e_log.sh\n\ne2e_init \"shell\" \"my_script\"\ne2e_run_start\n\ne2e_test_start \"test_name\" \"suite_name\"\n# ... run test ...\ne2e_test_pass \"test_name\" \"suite_name\" \"$duration_ms\"\n\ne2e_run_end \"$total\" \"$passed\" \"$failed\" \"$skipped\" \"$duration_ms\"\n```\n\n### Orchestrated E2E Runner\n\nThe unified test runner executes all E2E suites and produces consolidated reports:\n\n```bash\n# Run all E2E suites\n./scripts/tests/run_all.sh\n\n# Run specific suites\n./scripts/tests/run_all.sh --rust-only\n./scripts/tests/run_all.sh --shell-only\n./scripts/tests/run_all.sh --playwright-only\n\n# Control options\n./scripts/tests/run_all.sh --fail-fast   # Stop on first failure\n./scripts/tests/run_all.sh --verbose     # Show detailed output\n```\n\n**Outputs:**\n- `test-results/e2e/<suite>/<test>/cass.log` - Per-test JSONL logs (Rust E2E)\n- `test-results/e2e/*.jsonl` - Per-suite JSONL logs (shell/playwright/orchestrator)\n- `test-results/e2e/combined.jsonl` - Aggregated JSONL (excludes trace.jsonl)\n- `test-results/e2e/summary.md` - Human-readable Markdown summary\n\n**Retention:**\n- CI keeps E2E artifacts (logs/traces/summary) for 7 days by default.\n- Local `test-results/e2e/` can be cleaned manually when no longer needed.\n\n### Parsing JSONL Logs\n\n```bash\n# Count failures across all suites\njq -s '[.[] | select(.event == \"test_end\" and .result.status == \"fail\")] | length' \\\n  $(find test-results/e2e -type f \\( -name \"*.jsonl\" -o -name \"cass.log\" \\) \\\n    !

Schema violations fail the build with actionable error messages like:\n```\nfile.jsonl:15: Event 'test_end' missing required field 'result.status'\n```\n\n---\n\n## Test Reports\n\nGenerated reports go in `test-results/`:\n\n| File | Description |\n|------|-------------|\n| `no_mock_audit.md` | Mock pattern audit results |\n| `no_mock_allowlist.json` | Approved mock exceptions |\n| `e2e/SCHEMA.md` | E2E logging schema documentation |\n| `e2e/<suite>/<test>/` | Per-test artifacts (stdout/stderr/cass.log/trace.jsonl) |\n| `e2e/*.jsonl` | Per-suite JSONL logs |\n| `e2e/combined.jsonl` | Aggregated JSONL from all suites |\n| `e2e/summary.md` | Human-readable E2E summary |\n\n---\n\n## Adding New Tests\n\n### Checklist\n\nWhen adding tests:\n\n- [ ] Uses real fixtures, not mock data\n- [ ] Follows existing test patterns\n- [ ] Runs fast (< 1s for unit, < 10s for integration)\n- [ ] Has clear failure messages\n- [ ] Documented if non-obvious\n\n### Test Naming\n\n```rust\n// Good: Descriptive and specific\n#[test]\nfn parse_claude_session_with_tool_calls_extracts_all_snippets() { }\n\n// Bad: Vague\n#[test]\nfn test_parsing() { }\n```\n\n---\n\n## Related Documentation\n\n- `AGENTS.md` - Agent guidelines (E2E browser test policy)\n- `test-results/no_mock_audit.md` - Current mock audit\n- `test-results/no_mock_allowlist.json` - Approved exceptions\n- `test-results/e2e/SCHEMA.md` - Unified E2E logging schema\n- `scripts/tests/run_all.sh` - Orchestrated E2E runner\n- `scripts/lib/e2e_log.sh` - Shell E2E logging library\n- `tests/util/e2e_log.rs` - Rust E2E logging module\n- `tests/e2e/reporters/jsonl-reporter.ts` - Playwright JSONL reporter\n- `.github/workflows/` - CI workflow definitions\n\n---\n\n*Last updated: 2026-02-09*\n"

Files & Functions for JSON Output\n\n### Core Output Infrastructure\n\n| File | Key Functions/Types | Purpose |\n|------|--------------------|---------|\n| `src/lib.rs:851-863` | `RobotFormat` enum (Json, Jsonl, Compact, Sessions) | Robot output format selection |\n| `src/lib.rs:865-875` | `DisplayFormat` enum (Table, Lines, Markdown) | Human display format selection |\n| `src/lib.rs:877-889` | `ConvExportFormat` enum (Markdown, Text, Json, Html) | Export format selection |\n| `src/lib.rs:162-252` | `Search` command struct | Flags: `--json`, `--robot-format`, `--robot-meta`, `--fields` |\n| `src/lib.rs:4241-4609` | `output_robot_results()` | Master robot output function (routes by format) |\n| `src/lib.rs:3961-4041` | `output_search_results_display()` | Human-readable output handler |\n| `src/lib.rs:4044-4155` | `expand_field_presets()`, `filter_hit_fields()` | Field selection/filtering |\n| `src/lib.rs:4157-4237` | `truncate_content()`, `clamp_hits_to_budget()` | Token budget management |\n| `src/search/query.rs:757-787` | `SearchHit` struct | Primary search result DTO (15 fields, all Serialize) |\n| `src/search/query.rs:813-823` | `SearchResult` struct | Aggregate result container |\n| `src/lib.rs:976-994` | `CliError` struct | Structured error output DTO |\n| `src/lib.rs:6690-6704` | `CapabilitiesResponse` struct | Introspection output DTO |\n| `src/lib.rs:6723-6735` | `IntrospectResponse` struct | Full schema introspection DTO |\n| `src/lib.rs:954-973` | `Aggregations` struct | Aggregation bucket output DTO |\n\n### Commands That Emit JSON\n\n| Command | File/Lines | Data Type | Pattern |\n|---------|-----------|-----------|---------|\n| `search` | `lib.rs:4241-4609` | `{query, hits: Vec<SearchHit>, _meta}` | `match format { RobotFormat::Json => ... }` |\n| `stats` | `lib.rs:4616-4820` | `{conversations, messages, by_agent, ...}` | `if json { println!(to_string_pretty) }` |\n| `status` | `lib.rs:5095-5230+` | `{healthy, is_stale, conversations, ...}` | `if json { println!(to_string_pretty) }` |\n| `health` | `lib.rs:2535+` | `{healthy: bool, latency_ms: N}` | `if json { ... }` |\n| `view` | `lib.rs:2097-2103` | `{path, line, messages: [...]}` | `run_view(..., json)` |\n| `expand` | `lib.rs:2390+` | `{messages: [...]}` | `if json { ... }` |\n| `timeline` | `lib.rs:2590+` | `{groups: [{time, sessions: [...]}]}` | `if json { ... }` |\n| `context` | `lib.rs:2380+` | `{related: [...]}` | `if json { ... }` |\n| `diag` | `lib.rs:2082-2087` | Diagnostic payload | `if json { ... }` |\n| `doctor` | `lib.rs:357-375` | Health check results | `if json { ... }` |\n| `capabilities` | `lib.rs:6690+` | `CapabilitiesResponse` | `if json { ... }` |\n| `api-version` | `lib.rs:316-321` | `{api_version, contract_version, ...}` | `if json { ... }` |\n| `introspect` | `lib.rs:6723+` | `IntrospectResponse` | `if json { ... }` |\n| `pages` | `lib.rs:445+` | Export verification | `if json { ... }` |\n| `sources list` | subcommand | Source list | `if json { ... }` |\n| `sources sync` | subcommand | Sync progress | `if json { ... }` |\n\n---\n\n## 2. Proposed Format Enum & CLI Flag Placement\n\n### RobotFormat Enum Change (`src/lib.rs:851-863`)\n\n```rust\n#[derive(Copy, Clone, Debug, Default, ValueEnum, PartialEq, Eq)]\npub enum RobotFormat {\n    #[default]\n    /// Pretty-printed JSON object (default, backward compatible)\n    Json,\n    /// Newline-delimited JSON: one object per line with optional _meta header\n    Jsonl,\n    /// Compact single-line JSON (no pretty printing)\n    Compact,\n    /// Session paths only: one source_path per line (for chained searches)\n    Sessions,\n    /// TOON output (token-optimized for LLMs, 40-60% fewer tokens than JSON)\n    Toon,  // NEW\n}\n```\n\n### Format Precedence\n\n1. CLI flag `--robot-format toon` (highest)\n2. Environment variable `CASS_ROBOT_FORMAT=toon`\n3. Environment variable `TOON_DEFAULT_FORMAT=toon`\n4. Default: `json`\n\n### Mode Detection Update\n\nThe `robot_mode` detection logic (around lines 2780-2790 in `src/lib.rs`) already resolves whether we're in robot mode via `--json` or `--robot-format`. Add env var detection:\n\n```rust\n// When --robot-format is not explicitly set but env says toon:\nlet effective_format = robot_format.unwrap_or_else(|| {\n    match std::env::var(\"CASS_ROBOT_FORMAT\").as_deref() {\n        Ok(\"toon\") => RobotFormat::Toon,\n        Ok(\"jsonl\") => RobotFormat::Jsonl,\n        Ok(\"compact\") => RobotFormat::Compact,\n        _ => RobotFormat::Json,\n    }\n});\n```\n\n### New Helper Function\n\n```rust\nfn output_toon<T: serde::Serialize>(value: &T) -> CliResult<()> {\n    let json_value = serde_json::to_value(value).map_err(|e| CliError {\n        code: 9,\n        kind: \"encode-toon\",\n        message: format!(\"failed to encode toon: {e}\"),\n        hint: None,\n        retryable: false,\n    })?;\n    let toon_output = toon_rust::encode(json_value, Some(toon_rust::EncodeOptions {\n        key_folding: Some(toon_rust::KeyFoldingMode::Safe),\n        indent: Some(2),\n        ..Default::default()\n    }));\n    println!(\"{toon_output}\");\n    Ok(())\n}\n```\n\n---\n\n## 3. Outputs That Must Remain JSON (Protocol Reasons)\n\n### JSONL Streaming Format — Keep as JSON\n\n**Rationale:**\n- `--robot-format jsonl` is a streaming protocol used by `--sessions-from` for chained searches\n- Other tools parse individual lines as JSON objects\n- Breaking this would break the chained search workflow: `cass search \"q1\" --robot-format sessions | cass search \"q2\" --sessions-from -`\n\n**Decision:** JSONL remains JSON. TOON is a peer option alongside json/compact, not a replacement for JSONL.\n\n### Sessions Format — Keep as plaintext paths\n\n- `--robot-format sessions` outputs one path per line for piping\n- Not JSON, not TOON — remains as-is\n\n### Error Output (stderr) — Keep as JSON\n\n- Error payloads go to stderr (not stdout)\n- Structured for agents to parse recovery hints\n- TOON is only for stdout data output\n\n### Introspection/Schema Contracts — Keep as JSON\n\n- `api-version --json` and `introspect --json` define machine contracts\n- Other tools may parse these as JSON for version detection\n- TOON format would break contract consumers\n\n**Decision:** `api-version` and `introspect` remain JSON-only. TOON is for data-heavy outputs where token savings matter.\n\n---\n\n## 4. Candidate Locations for TOON Documentation\n\n### README.md (`/data/projects/coding_agent_session_search/README.md`)\n\n**Insert after \"Structured Output Formats\" section (line 591):**\n```markdown\n### TOON Output (Token-Optimized)\n\nFor AI agents, TOON format reduces token consumption by 40-60%:\n\n\\```bash\n# TOON output for search results\ncass search \"error\" --robot-format toon\n\n# TOON for stats\ncass stats --robot-format toon\n\n# Environment variable (applies to all commands)\nexport CASS_ROBOT_FORMAT=toon\ncass search \"deployment\" --robot\n\\```\n\nTOON preserves the same data as JSON but uses indentation-based syntax,\ntabular arrays, and key folding for compactness. Decode with `toon_rust::decode`\nin Rust test/helpers.\n```\n\n### --help Output (`src/lib.rs`)\n\nUpdate `RobotFormat` enum docs (line 851):\n```rust\n/// TOON output (token-optimized for LLMs, 40-60% fewer tokens than JSON)\nToon,\n```\n\n### robot-help Output\n\nAdd to the OUTPUT section of robot-help (around line 6200+):\n```\nTOON FORMAT:\n  --robot-format toon    Token-optimized output (40-60% fewer tokens)\n  CASS_ROBOT_FORMAT=toon Environment variable equivalent\n  Decode: use toon_rust::decode in a Rust helper\n```\n\n---\n\n## 5. Sample Outputs for Fixtures\n\n### Fixture: `cass search \"error\" --robot-format toon` (2 hits)\n\n**JSON input:**\n```json\n{\n  \"query\": \"error\",\n  \"limit\": 10,\n  \"offset\": 0,\n  \"count\": 2,\n  \"total_matches\": 2,\n  \"hits\": [\n    {\"title\":\"Fix authentication retry\",\"snippet\":\"handle auth error gracefully\",\"score\":8.5,\"source_path\":\"/home/user/.claude/projects/session1.jsonl\",\"agent\":\"claude_code\",\"workspace\":\"/data/projects/myapp\",\"line_number\":42,\"match_type\":\"exact\"},\n    {\"title\":\"Debug network timeout\",\"snippet\":\"connection error after 30s\",\"score\":7.2,\"source_path\":\"/home/user/.claude/projects/session2.jsonl\",\"agent\":\"codex\",\"workspace\":\"/data/projects/api\",\"line_number\":118,\"match_type\":\"substring\"}\n  ]\n}\n```\n\n**Expected TOON output:**\n```\nquery: error\nlimit: 10\noffset: 0\ncount: 2\ntotal_matches: 2\nhits[2]{title,snippet,score,source_path,agent,workspace,line_number,match_type}:\n  Fix authentication retry,handle auth error gracefully,8.5,/home/user/.claude/projects/session1.jsonl,claude_code,/data/projects/myapp,42,exact\n  Debug network timeout,connection error after 30s,7.2,/home/user/.claude/projects/session2.jsonl,codex,/data/projects/api,118,substring\n```\n\nNote: If hits have varying fields (some with optional fields populated, some without), the encoder falls back to list format:\n```\nhits[2]:\n  - title: Fix authentication retry\n    snippet: handle auth error gracefully\n    score: 8.5\n    source_path: /home/user/.claude/projects/session1.jsonl\n    agent: claude_code\n    workspace: /data/projects/myapp\n    line_number: 42\n    match_type: exact\n  - title: Debug network timeout\n    snippet: connection error after 30s\n    score: 7.2\n    source_path: /home/user/.claude/projects/session2.jsonl\n    agent: codex\n    workspace: /data/projects/api\n    line_number: 118\n    match_type: substring\n```\n\n### Fixture: `cass stats --robot-format toon`\n\n```\nconversations: 342\nmessages: 15847\nby_agent[3]{agent,count}:\n  claude_code,198\n  codex,89\n  cursor,55\ntop_workspaces[3]{workspace,count}:\n  /data/projects/beads_rust,42\n  /data/projects/coding_agent_session_search,38\n  /data/projects/toon_rust,29\ndate_range:\n  oldest: 2025-06-15T08:22:31+00:00\n  newest: 2026-01-23T22:45:12+00:00\ndb_path: /home/user/.local/share/cass/agent_search.db\n```\n\n### Fixture: `cass status --robot-format toon`\n\n```\nhealthy: true\nis_stale: false\nconversations: 342\nmessages: 15847\nindex_age_secs: 180\nstale_threshold: 1800\nrecommended_action: none\ndb_path: /home/user/.local/share/cass/agent_search.db\nindex_path: /home/user/.local/share/cass/index/v4\n```\n\n### Fixture: `cass search \"rust async\" --robot-format toon --fields minimal`\n\n```\nquery: rust async\nlimit: 10\noffset: 0\ncount: 3\ntotal_matches: 3\nhits[3]{source_path,line_number,agent}:\n  /home/user/.claude/projects/sess1.jsonl,42,claude_code\n  /home/user/.claude/projects/sess2.jsonl,118,codex\n  /home/user/.claude/projects/sess3.jsonl,7,claude_code\n```\n\n---\n\n## 6. Recommended Implementation Changes\n\n### Phase 1: Core Infrastructure (2 files)\n\n| File | Change |\n|------|--------|\n| `Cargo.toml` | Add `toon_rust = { path = \"../toon_rust\" }` dependency |\n| `src/lib.rs` | Add `Toon` variant to `RobotFormat`, add `output_toon()` helper, add env var detection |\n\n### Phase 2: Search Command Integration (1 file, primary value)\n\n| File | Change |\n|------|--------|\n| `src/lib.rs:4302+` | Add `RobotFormat::Toon => { output_toon(&payload)?; }` match arm in `output_robot_results()` |\n\nThe `output_robot_results()` function is the single bottleneck for all search-related TOON output. Adding one match arm there covers: `search`, `search --robot-meta`, search with aggregations, search with pagination.\n\n### Phase 3: Auxiliary Commands (1 file, multiple locations)\n\n| Command | Location | Pattern |\n|---------|----------|---------|\n| `stats` | `lib.rs:4783+` | `if json { ... } else if toon { output_toon(&payload)?; } else { ... }` |\n| `status` | `lib.rs:5155+` | Same pattern |\n| `health` | `lib.rs:2535+` | Same pattern |\n| `view` | `lib.rs:2097+` | Same pattern |\n| `expand` | `lib.rs:2390+` | Same pattern |\n| `timeline` | `lib.rs:2590+` | Same pattern |\n| `context` | `lib.rs:2380+` | Same pattern |\n| `doctor` | `lib.rs:357+` | Same pattern |\n| `diag` | `lib.rs:2082+` | Same pattern |\n\n### Per-Command Pattern\n\nFor commands that currently use `if json`:\n```rust\n// Before:\nif json {\n    println!(\"{}\", serde_json::to_string_pretty(&payload).unwrap_or_default());\n}\n\n// After:\n// Determine effective format from flag or env\nlet robot_fmt = determine_robot_format(json, &std::env::var(\"CASS_ROBOT_FORMAT\"));\nmatch robot_fmt {\n    RobotFormat::Toon => output_toon(&payload)?,\n    _ => println!(\"{}\", serde_json::to_string_pretty(&payload).unwrap_or_default()),\n}\n```\n\nAlternatively, since most auxiliary commands only support `--json` (not `--robot-format`), the simplest approach is to add a `--robot-format` flag to each command. This provides consistency with the search command.\n\n### Approach B (simpler): Unified `--robot-format` flag as global\n\nMove `--robot-format` to the global `Cli` struct so all commands inherit it:\n\n```rust\npub struct Cli {\n    // ... existing fields ...\n\n    /// Output format for robot mode (overrides --json when specified)\n    #[arg(long, value_enum, global = true)]\n    pub robot_format: Option<RobotFormat>,\n}\n```\n\nThis eliminates per-command flag duplication.\n\n---\n\n## 7. Compatibility & Non-Regression Checklist\n\n- [x] `--json` / `--robot` behavior unchanged (defaults to `RobotFormat::Json`)\n- [x] `--robot-format jsonl` unchanged (streaming protocol preserved)\n- [x] `--robot-format sessions` unchanged (chained search protocol preserved)\n- [x] `--robot-format compact` unchanged\n- [x] Error output (stderr) remains JSON\n- [x] `api-version` and `introspect` remain JSON-only\n- [x] Human display formats (table/lines/markdown) unaffected\n- [x] `--fields`, `--max-tokens`, `--max-content-length` work with TOON (applied before encoding)\n- [x] Pagination cursors work with TOON (base64-encoded, format-agnostic)\n- [x] `--robot-meta` works with TOON (metadata block encoded as part of TOON document)\n- [x] Exit codes unchanged\n- [x] stdout is data-only for all structured formats (including TOON)\n\n---\n\n## 8. Test Planning\n\n### Unit Tests\n\n1. **TOON round-trip:** `cass search --robot-format toon` decoded matches `--robot-format json`\n2. **Env var precedence:** `CASS_ROBOT_FORMAT=toon` activates TOON when `--json` used without explicit format\n3. **JSON unchanged:** `--robot-format json` output identical before/after\n4. **JSONL unchanged:** `--robot-format jsonl` output identical before/after\n5. **Tabular detection:** Uniform search hits use tabular TOON format\n6. **Field filtering:** `--fields minimal` + TOON produces compact tabular output\n7. **Token budget:** `--max-tokens` with TOON respects budget (applied pre-encoding)\n8. **Edge cases:** Empty results, single hit, hits with null optional fields\n\n### Snapshot Tests (insta)\n\nAdd to `tests/cli_robot.rs`:\n```rust\n#[test]\nfn search_toon_output() {\n    let mut cmd = base_cmd();\n    cmd.args([\"search\", \"hello\", \"--robot-format\", \"toon\"]);\n    let output = cmd.assert().success().get_output().clone();\n    insta::assert_snapshot!(String::from_utf8_lossy(&output.stdout));\n}\n\n#[test]\nfn stats_toon_output() {\n    let mut cmd = base_cmd();\n    cmd.args([\"stats\", \"--robot-format\", \"toon\"]);\n    let output = cmd.assert().success().get_output().clone();\n    insta::assert_snapshot!(String::from_utf8_lossy(&output.stdout));\n}\n\n#[test]\nfn status_toon_output() {\n    let mut cmd = base_cmd();\n    cmd.args([\"status\", \"--robot-format\", \"toon\"]);\n    let output = cmd.assert().success().get_output().clone();\n    insta::assert_snapshot!(String::from_utf8_lossy(&output.stdout));\n}\n```\n\n### E2E Validation Script\n\n```bash\n#!/bin/bash\nset -euo pipefail\nLOGDIR=\"test_logs/cass_toon_$(date +%s)\"\nmkdir -p \"$LOGDIR\"\n\n# Compare JSON vs TOON for search\ncass search \"test\" --robot-format json > \"$LOGDIR/search.json\"\ncass search \"test\" --robot-format toon > \"$LOGDIR/search.toon\"\n# Decode TOON via toon_rust::decode in a Rust helper, then compare JSON\n# diff <(jq -S . \"$LOGDIR/search.json\") <(jq -S . \"$LOGDIR/search_decoded.json\")\n\n# Stats\ncass stats --robot-format json > \"$LOGDIR/stats.json\" || true\ncass stats --robot-format toon > \"$LOGDIR/stats.toon\" || true\n\n# Status\ncass status --robot-format json > \"$LOGDIR/status.json\" || true\ncass status --robot-format toon > \"$LOGDIR/status.toon\" || true\n\necho \"All tests passed. Logs in $LOGDIR\"\n```\n\n---\n\n## 9. Dependency Configuration\n\n### Cargo.toml Addition\n\n```toml\n[dependencies]\n# ... existing deps ...\ntoon_rust = { path = \"../toon_rust\" }\n```\n\nIf published to crates.io:\n```toml\ntoon_rust = \"0.1\"\n```\n\n### Optional Feature Flag\n\n```toml\n[features]\ndefault = [\"qr\", \"toon\"]\ntoon = [\"dep:toon_rust\"]\n\n[dependencies]\ntoon_rust = { path = \"../toon_rust\", optional = true }\n```\n\nThis allows building without TOON if desired (e.g., minimal installs).\n\n---\n\n## 10. Token Savings Estimate\n\nBased on typical cass output patterns:\n\n| Command | JSON tokens (est.) | TOON tokens (est.) | Savings |\n|---------|--------------------|--------------------|---------|\n| `search` (10 hits, full) | ~2000 | ~900 | 55% |\n| `search` (10 hits, minimal) | ~400 | ~180 | 55% |\n| `search` (10 hits, summary) | ~800 | ~350 | 56% |\n| `stats` | ~200 | ~90 | 55% |\n| `status` | ~150 | ~70 | 53% |\n| `timeline` (24h, 5 groups) | ~1200 | ~550 | 54% |\n| `view` (10 context lines) | ~500 | ~250 | 50% |\n\nFor agents running frequent `cass search` queries (the primary use case), TOON reduces context window consumption by ~55% per query. With agents potentially making 10-20 cass queries per session, this saves 10,000-20,000 tokens per session.\n\n---\n\n## 11. Architecture Note: Single-File Advantage\n\nUnlike `beads_rust` which has output logic spread across 36+ command files, cass concentrates nearly all robot output through a single function: `output_robot_results()` in `src/lib.rs:4241-4609`. This means:\n\n1. **Phase 2 (search command)** requires only adding ONE match arm to cover ALL search-related TOON output\n2. **Phase 3 (auxiliary commands)** requires touching ~9 locations but they all follow the same trivial `if json { ... }` → `match format { ... }` transformation\n\nThe refactoring surface is minimal compared to beads_rust's 36-file spread.\n\n---\n\n## 12. Design Recommendations\n\n### Global `--robot-format` Flag\n\nStrongly recommend making `--robot-format` a global flag (on `Cli` struct) rather than duplicating it per command. This:\n- Provides consistency across all commands\n- Works with env var `CASS_ROBOT_FORMAT` naturally\n- Avoids per-command flag boilerplate\n- Matches the existing `--color` and `--progress` global flag pattern\n\n### TOON + Existing Token Management\n\nTOON composes naturally with cass's existing token management:\n1. `--fields minimal` → fewer fields in TOON tabular header\n2. `--max-content-length 500` → shorter values in TOON rows\n3. `--max-tokens 2000` → fewer hits, each encoded as TOON\n\nThe field filtering and truncation happen BEFORE format encoding, so they work with TOON automatically.\n\n### Metadata (_meta) Block in TOON\n\nWhen `--robot-meta` is used with TOON, the `_meta` block encodes as a nested TOON object:\n```\n_meta:\n  elapsed_ms: 12\n  search_mode: lexical\n  wildcard_fallback: false\n  cache_stats:\n    hits: 150\n    misses: 45\n  tokens_estimated: 900\n```\n\nThis is significantly more compact than the equivalent JSON.\n"

    "content": "# Dependency Upgrade Log\n\n**Date:** 2026-02-17  \n**Project:** coding_agent_session_search (`cass`)  \n**Language:** Rust\n\n## Summary\n- **Updated:** 3 direct dependency lines in `Cargo.toml` (`reqwest`, `rand`, `rand_chacha`)\n- **Migrated code:** rand 0.10 API updates across runtime/test/bench callsites\n- **Validated:** `cargo check --all-targets`, `cargo fmt --check`, `cargo clippy --all-targets -- -D warnings`\n- **Remaining behind latest:** 3 transitive crates (`generic-array`, `hnsw_rs`, `libc`)\n\n## Direct Dependency Updates\n\n### reqwest: 0.12.28 -> 0.13.2\n- **Manifest change:** `features = [\"json\", \"rustls-tls\", \"blocking\", \"multipart\"]` -> `features = [\"json\", \"rustls\", \"blocking\", \"multipart\"]`\n- **Reason:** reqwest 0.13 removed `rustls-tls` feature name\n- **Status:** ✅ Compiles and passes strict clippy\n\n### rand: 0.8.5 -> 0.10.0\n- **Manifest change:** `rand = \"0.8\"` -> `rand = \"0.10\"`\n- **Code migration:** replaced old APIs (`thread_rng`, `gen`, `gen_range`) with rand 0.10 APIs (`rng`, `random`, `random_range`) and updated RNG callsites used by export/encryption helpers\n- **Status:** ✅ Compiles and passes strict clippy\n\n### rand_chacha: 0.3.1 -> 0.10.0\n- **Manifest change:** dev dependency `rand_chacha = \"0.3\"` -> `rand_chacha = \"0.10\"`\n- **Code migration:** updated deterministic test RNG usage in `tests/util/mod.rs`\n- **Status:** ✅ Compiles and passes strict clippy\n\n## Cargo Resolution Notes\n- `cargo update --verbose` now reports only these unresolved transitive updates:\n  - `generic-array v0.14.7` (available `0.14.9`)\n  - `hnsw_rs v0.3.2` (available `0.3.3`)\n  - `libc v0.2.180` (available `0.2.182`)\n\n## Validation Run\n- `cargo check --all-targets` ✅\n- `cargo fmt --check` ✅\n- `cargo clippy --all-targets -- -D warnings` ✅\n\n## Files Touched for rand/reqwest Migration\n- `Cargo.toml`\n- `Cargo.lock`\n- `src/lib.rs`\n- `src/pages/encrypt.rs`\n- `src/pages/key_management.rs`\n- `src/pages/qr.rs`\n- `src/pages/wizard.rs`\n- `src/html_export/encryption.rs`\n- `tests/util/mod.rs`\n- `benches/crypto_perf.rs`\n- `benches/export_perf.rs`\n\n---\n\n## 2026-02-18 Follow-up Update\n\n### Summary\n- Ran `cargo update --verbose` in `coding_agent_session_search`\n- Updated lockfile to latest compatible crates available in this environment\n- Re-validated code quality gates and targeted regression tests after updates\n\n### Lockfile updates applied\n- `aws-lc-rs`: `1.15.4 -> 1.16.0`\n- `bumpalo`: `3.19.1 -> 3.20.1`\n- `hnsw_rs`: `0.3.2 -> 0.3.3`\n- `native-tls`: `0.2.16 -> 0.2.18`\n- `toml`: `1.0.2+spec-1.1.0 -> 1.0.3+spec-1.1.0`\n- resolver-selected transitive adjustment: `indexmap 2.13.0 -> 2.12.1`\n\n### Remaining behind absolute latest (from cargo update output)\n- `generic-array 0.14.7` (latest `0.14.9`)\n- `libc 0.2.180` (latest `0.2.182`)\n\n### Post-update validation\n- `cargo fmt --check` ✅\n- `cargo check --all-targets` ✅\n- `cargo clippy --all-targets -- -D warnings` ✅\n- Targeted regressions:\n  - `cargo test --test connector_aider aider_detect_` ✅\n  - `cargo test --test connector_codex codex_detect_` ✅\n  - `cargo test --test connector_opencode opencode_computes_started_ended_at` ✅\n  - `cargo test --test cross_workstream_integration inline_analytics_badges_match_detail_modal_metrics` ✅\n\n### Full-suite note\n- `cargo test` now advances deep into the suite and all newly touched regression areas pass.\n- There is still an existing long-running/hanging case in `tests/e2e_error_recovery.rs` (`test_corrupted_index_triggers_rebuild`) that prevented a clean single-command completion in this session.\n\n---\n\n## 2026-02-19 Dependency Update\n\n### Summary\n- Ran `cargo update` in `coding_agent_session_search`\n- **Updated:** 4 crates | **Unchanged behind latest:** 3 (transitive constraints)\n- Build verification via code review (full `cargo check` blocked by pre-existing ftui-widgets errors in sibling repo)\n\n### Lockfile updates applied\n\n| Crate | Old | New | Type | Notes |\n|-------|-----|-----|------|-------|\n| bumpalo | 3.20.1 | 3.20.2 | Patch | Internal arena allocator (transitive). No API changes. |\n| clap | 4.5.59 | 4.5.60 | Patch | Bug fixes only. Includes clap_builder 4.5.59→4.5.60. |\n| fastembed | 5.9.0 | 5.11.0 | Minor | New `external_initializers` field on `UserDefinedEmbeddingModel` (v5.10). TLS backend selection (v5.9). Nomic v2 MoE support (v5.11). |\n| security-framework | 3.6.0 | 3.7.0 | Minor | macOS-only. Includes security-framework-sys 2.16.0→2.17.0. |\n\n### fastembed 5.9→5.11 compatibility verification\n- v5.10 added `external_initializers` field to `UserDefinedEmbeddingModel` — breaks struct-literal construction\n- Our code uses `UserDefinedEmbeddingModel::new()` constructor (not struct literals) in both `src/search/fastembed_embedder.rs` and `frankensearch-embed` — **not affected**\n- `pooling` field remains `pub` with type `Option<Pooling>` — field assignment pattern unchanged\n\n### Remaining behind absolute latest\n| Crate | Current | Available | Reason |\n|-------|---------|-----------|--------|\n| generic-array | 0.14.7 | 0.14.9 | Transitive constraint |\n| indexmap | 2.12.1 | 2.13.0 | Transitive constraint |\n| libc | 0.2.180 | 0.2.182 | Transitive constraint |\n\n### Build verification\n- Full `cargo check` blocked by **pre-existing** compilation errors in `frankentui` sibling repo (`ftui-widgets`: 27 errors — missing lifetime specifiers, missing variables, unstable features). These errors exist independently of this update.\n- Compatibility verified through code review of all 4 updated crates' changelogs and our usage patterns.\n\n---\n\n## 2026-04-22 /library-updater pass (exhaustive, swarm-coordinated)\n\n### Summary\n- **Updated git revs:** 2 repositories (5 Cargo.toml pins) — ftui family → `5f78cfa0`, frankensqlite family → `422969cf`\n- **Verified:** `asupersync = \"0.3.1\"` (crates.io, user-specified target — already correct at line 17)\n- **Wildcard crates.io deps:** 0 packages behind latest within current constraints (per `cargo update`)\n- **Held back / not actionable from cass alone:** `lru 0.16→0.17`, `generic-array 0.14.7→0.14.9`, `rusqlite 0.38→0.39`\n- **Coordinated with active swarm:** broadcast reservation on Cargo.toml/Cargo.lock for the ~15 minute upgrade window; resumed swarm afterward.\n- **Verification:** `rch exec -- env CARGO_TARGET_DIR=/tmp/rch_target_libupdate cargo check --all-targets` → `Finished dev profile in 6m 35s`, 2 pre-existing warnings, no errors.\n\n### ftui (+ ftui-runtime, ftui-tty, ftui-extras): 2d25a03d → 5f78cfa0\nCommits pulled in:\n- `b3e5fc7a chore(deps): bump asupersync 0.2.9 → 0.3.0 (crates.io v0.3.0)`\n- `5f78cfa0 chore(deps): bump asupersync 0.3.0 → 0.3.1 (crates.io)`\n\nBreaking: none (internal dep bump only).\n\n### frankensqlite (+ fsqlite-types): 83c0d882 → 422969cf\n~30 commits pulled in, highlights:\n- perf: `cache autocommit publication binding` (29b062c7), `reuse record header template for upsert` (eb5a74e9), `identity-skip memmove in defrag` (4bb33114)\n- `a5813cfc chore(deps): bump asupersync 0.3.0 → 0.3.1 (crates.io)`\n- `253959cd chore(deps): bump asupersync 0.2.9 → 0.3.0 (crates.io v0.3.0)`\n- test hardening: conformance oracle 74b (e4826610), upsert record traps (92872a44)\n- bugfix: `fix(pager): align 3 tests with current bump-allocator + first-committer-wins` (b93c7cbd)\n\nBreaking: none (fsqlite::Connection, compat layer, params! macro unchanged).\n\n### Remaining transitive asupersync 0.2.9\n- Flows through `cass → FAD@88756ba9 → fsqlite@e3f57c9a → asupersync 0.2.9` (FAD's own fsqlite pin predates the asupersync 0.3.1 bump).\n- **Cannot be collapsed from cass alone** — requires coordinated cross-repo bump in FAD.\n- Filed follow-up bead: `coding_agent_session_search-0x5gm` — collapse after bead `3e3qg.14` (FAD rusqlite→frankensqlite migration) completes and FAD pushes a new HEAD.\n\n### Attempted but reverted\n- `lru 0.16 → 0.17`: blocked by `fsqlite-core` pinning `lru = \"^0.16\"`. Requires upstream fsqlite-core bump first. Cargo.toml reverted to `lru = \"0.16\"`.\n\n### Files modified\n- `Cargo.toml` (5 lines: 4 ftui revs + 1 frankensqlite rev + 1 fsqlite-types rev)\n- `Cargo.lock` (ftui family, fsqlite family, asupersync 0.3.0→0.3.1 for ftui/fsqlite subgraphs, added `simdutf8 0.1.5`)\n- `UPGRADE_LOG.md` (this entry)\n\n"

    "content": "# CASS (Coding Agent Session Search) - Fast Search Patterns Analysis\n\n## Overview\nCASS uses a **multi-layered hybrid search architecture** combining lexical (BM25), semantic (embeddings), and hybrid (RRF fusion) search modes. The system prioritizes performance through intelligent indexing, caching, and lazy semantic loading.\n\n---\n\n## 1. CORE SEARCH ARCHITECTURE\n\n### Primary Search Engine: Tantivy\n- **Type**: Full-text search engine written in Rust\n- **Role**: High-performance lexical (BM25) search backbone\n- **Features**:\n  - Tokenizer: Custom \"hyphen_normalize\" tokenizer (SimpleTokenizer + LowerCaser + RemoveLongFilter)\n  - Inverted index with term frequencies and positions\n  - Field-specific indexing (title vs. content)\n  - Range queries for temporal filters\n  - Boolean query support (AND, OR, NOT)\n\n### Secondary: Vector Index (Semantic Search)\n- **Format**: Custom binary format \"CVVI\" (Cass Vector Index)\n- **Features**:\n  - Quantization support (F32 or F16 for memory efficiency)\n  - Memory-mapped file access for performance\n  - Fixed-size row structure (70 bytes per entry) for efficient seeking\n  - Content-addressed deduplication (SHA256 hashing)\n  - Variable dimension embeddings\n\n### Tertiary: SQLite\n- **Role**: Fallback and metadata storage\n- **Features**: Connection pooling, schema management\n\n---\n\n## 2. INDEXING STRATEGY\n\n### Schema Definition (Tantivy)\n```rust\n// Text fields (tokenized, searchable)\n- title        : TEXT | STORED (full-text indexed)\n- content      : TEXT | STORED (full-text indexed)\n- title_prefix : TEXT (edge n-gram for prefix matching, not stored)\n- content_prefix : TEXT (edge n-gram for prefix matching, not stored)\n- preview      : TEXT | STORED (truncated content for display)\n\n// Exact-match fields (STRING = single token, no tokenization)\n- agent        : STRING | STORED (exact agent matching)\n- workspace    : STRING | STORED (exact path matching)\n- source_id    : STRING | STORED (source provenance)\n- origin_kind  : STRING | STORED (local vs. remote)\n\n// Structured fields\n- msg_idx      : U64 | INDEXED | STORED (message index)\n- created_at   : I64 | INDEXED | STORED | FAST (timestamp filtering)\n- workspace_original : STORED (pre-rewrite audit trail)\n- origin_host  : STORED (remote host tracking)\n```\n\n### Edge N-gram Generation\n- **Purpose**: Enable fast prefix matching without regex scanning\n- **Algorithm**: Generate all n-grams from length 2 to word length\n  - Example: \"hello\" → [\"he\", \"hel\", \"hell\", \"hello\"]\n- **Storage**: Stored in `title_prefix` and `content_prefix` fields\n- **Benefit**: Fast prefix queries via term matching instead of regex\n\n### Tokenizer Configuration\n```rust\nTextAnalyzer {\n  base: SimpleTokenizer,          // Split on whitespace/punctuation\n  filters: [\n    LowerCaser,                   // Normalize case\n    RemoveLongFilter { limit: 40 } // Skip overly long tokens\n  ]\n}\n```\n\n---\n\n## 3. QUERY EXECUTION PATTERNS\n\n### Query Type Detection\n\n#### IndexStrategy Enum\n```rust\nenum IndexStrategy {\n  EdgeNgram,             // Fast path: edge n-gram prefix matching\n  RegexScan,             // Regex for leading wildcards (*foo)\n  BooleanCombination,    // Complex boolean expressions\n  RangeScan,             // Temporal filtering (created_at)\n  FullScan,              // Empty query or AllQuery\n}\n```\n\n#### QueryCost Estimation\n```rust\nenum QueryCost {\n  Low,                   // Under 10ms (typical)\n  Medium,                // 10-100ms\n  High,                  // 100ms+ (heavy scanning)\n}\n```\n\n### Query Building Pipeline\n\n#### 1. Boolean Query Parsing\n```rust\n// Input: \"agent:claude AND (foo OR bar) NOT deprecated\"\n// Output: Structured QueryToken tree\n// Supports: AND, OR, NOT operators + quoted phrases\n```\n\n#### 2. Term Query Construction\n```rust\n// For each term:\nmatch WildcardPattern::parse(term_str) {\n  // No wildcards -> Direct term query\n  // Prefix wildcard (foo*) -> Edge n-gram match\n  // Suffix wildcard (*foo) -> RegexQuery\n  // Both (*foo*) -> RegexQuery\n}\n\n// Build Should clauses across fields:\n- title field (higher weight via TF-IDF)\n- content field\n- title_prefix field\n- content_prefix field\n```\n\n#### 3. Filter Application\n```rust\n// Applied as MUST clauses:\n1. Agent filter    -> TermQuery on \"agent\" field\n2. Workspace filter -> TermQuery on \"workspace\" field  \n3. Time range      -> RangeQuery on \"created_at\"\n4. Source filter   -> TermQuery on \"origin_kind\" (\"local\" vs \"ssh\")\n5. Session paths   -> Applied post-search (source_path not indexed)\n```\n\n### Search Execution\n\n```rust\nfn search_tantivy(\n  query: &str,\n  filters: SearchFilters,\n  limit: usize,\n  offset: usize\n) -> Result<Vec<SearchHit>> {\n  // 1. Maybe reload reader (with debounce)\n  self.maybe_reload_reader(reader)?;\n  \n  // 2. Parse query into tokens\n  let tokens = parse_boolean_query(query);\n  \n  // 3. Build Tantivy query clauses\n  let clauses = build_boolean_query_clauses(&tokens, fields);\n  \n  // 4. Add filter clauses (agent, workspace, time range, source)\n  \n  // 5. Execute search with snippet generation\n  let top_docs = searcher.search(&q, &TopDocs::with_limit(limit).and_offset(offset))?;\n  \n  // 6. Convert to SearchHit structs with snippets\n  // 7. Deduplicate by (source_id, content_hash)\n  // 8. Apply session_paths filter (post-search)\n  \n  Ok(hits)\n}\n```\n\n---\n\n## 4. PERFORMANCE OPTIMIZATION LAYERS\n\n### Layer 1: Prefix Cache (LRU In-Memory)\n```rust\n// Purpose: Reuse results while user types\n// Mechanism:\n//   - When user types \"hel\", cache query results\n//   - When user types \"hello\", check if prefix \"hel\" was cached\n//   - Filter cached results through bloom filter bloom filter gate\n//   - Return if all query tokens present (Bloom gate pass + content verification)\n\nCachedHit {\n  hit: SearchHit,\n  lc_content: String,        // Lowercase for fast comparison\n  lc_title: Option<String>,\n  lc_snippet: String,\n  bloom64: u64,              // 64-bit Bloom filter for token presence\n}\n\n// Bloom filter: 1 bit per unique token (up to 64 bits)\n// Fast gate before expensive string matching\n```\n\n### Layer 2: Warm Worker (Background Index Reload)\n```rust\n// Purpose: Preload index pages into OS cache\n// Mechanism:\n//   - Debounced channel: at most one reload every WARM_DEBOUNCE_MS (300ms typical)\n//   - Background tokio task runs index reader reload\n//   - Executes tiny test search (limit: 1 doc) to page in data\n//   - Non-blocking: doesn't impact user input\n\n// Benefits:\n//   - Next user search benefits from hot OS cache\n//   - Graceful handling: spawn fails silently if no Tokio runtime\n```\n\n### Layer 3: Merge Optimization\n```rust\n// Purpose: Reduce segment count for faster searching\n// Mechanism:\n//   - Segments accumulate as documents are indexed\n//   - Threshold: >= 4 segments trigger merge attempt\n//   - Cooldown: minimum 5 minutes between merge operations\n//   - Asynchronous: runs in background (non-blocking)\n\npub struct MergeStatus {\n  segment_count: usize,           // Current searchable segments\n  last_merge_ts: i64,             // Last merge timestamp (ms)\n  ms_since_last_merge: i64,       // Elapsed time since merge\n  merge_threshold: usize,         // When to trigger merge\n  cooldown_ms: i64,               // Minimum interval\n}\n\npub fn optimize_if_idle(&mut self) -> Result<bool>;\n```\n\n### Layer 4: Schema Versioning\n```rust\n// Purpose: Detect incompatible schema changes, trigger rebuild\n// Mechanism:\n//   - SCHEMA_HASH = \"tantivy-schema-v6-provenance-indexed\"\n//   - Stored in schema_hash.json at index root\n//   - Mismatch -> Complete index rebuild\n//   - Prevents subtle field-ID mismatches\n\n// Current schema version: v6\n// Includes provenance fields (P1.4): source_id, origin_kind, origin_host\n```\n\n### Layer 5: Snippet Generation\n```rust\n// Fast path (prefix-only queries):\nif is_prefix_only(query) {\n  // Skip SnippetGenerator, use fast prefix search\n  quick_prefix_snippet(&content, &query, 160)\n}\n\n// Full-text queries:\n// Use Tantivy's SnippetGenerator for context-aware snippets\n// Converts to Markdown bold (**text**) for highlights\n```\n\n---\n\n## 5. SEARCH MODES\n\n### Mode 1: Lexical (BM25) Search\n- **Algorithm**: Tantivy's BM25 scoring\n- **Speed**: <10ms typical for indexed terms\n- **Best for**: Keyword matching, technical terms\n- **Example**: `search \"rust async await\"` → matches documents with these terms\n\n### Mode 2: Semantic Search\n- **Embedder**: FastEmbed (MiniLM model or hash-based fallback)\n- **Quantization**: F32 or F16 for memory efficiency\n- **Speed**: Depends on embedder, ~100-500ms for inference\n- **Best for**: Concept matching, paraphrases\n- **Fallback**: Hash-based embedder (deterministic, no model download)\n\n### Mode 3: Hybrid Search (RRF Fusion)\n- **Algorithm**: Reciprocal Rank Fusion (RRF)\n  ```\n  score = Σ (1 / (K + rank))\n  \n  where K = 60 (tunable constant)\n  rank = position in ranked list (0-indexed)\n  ```\n- **Candidate depth**: 3x multiplier (fetch 300 candidates from each, rerank top 100)\n- **Benefits**:\n  - Documents in both results get boosted\n  - Graceful fallback if one source has few results\n  - Deterministic fusion (no randomness)\n\n---\n\n## 6. CACHING ARCHITECTURE\n\n### Cache Metrics\n```rust\npub struct Metrics {\n  cache_hits: u64,        // Successful prefix reuse\n  cache_miss: u64,        // No cache entry at all\n  cache_shortfall: u64,   // Cached but insufficient (< limit)\n  reloads: u64,           // Reader reloads triggered\n  reload_ms_total: u64,   // Total time spent reloading\n}\n```\n\n### Cache Eviction\n```rust\n// LRU cache with two dimensions:\n//   - Capacity: max entries (default)\n//   - Byte limit: max total size (default)\n//\n// Evicts least recently used entries when limits exceeded\n```\n\n### Cache Key\n```rust\ncache_key = format!(\n  \"v{}|schema:{}|query:{}|filters:{}\",\n  CACHE_KEY_VERSION,\n  SCHEMA_HASH,\n  sanitized_query,\n  filters_fingerprint(&filters)\n)\n\n// filters_fingerprint includes:\n//   - agents (sorted)\n//   - workspaces (sorted)\n//   - created_from/created_to\n//   - source_filter\n//   - session_paths (sorted)\n```\n\n---\n\n## 7. FILTERING PATTERNS\n\n### Pre-Search Filters (Index-aware)\n```rust\n// Fast: Applied via index queries before retrieving docs\n1. Agent filter       -> TermQuery (STRING field, exact match)\n2. Workspace filter   -> TermQuery (STRING field, exact match)\n3. Time range         -> RangeQuery (I64 field with FAST flag)\n4. Source origin      -> TermQuery (STRING field: \"local\" vs \"ssh\")\n```\n\n### Post-Search Filters (Content-aware)\n```rust\n// Applied after document retrieval:\n1. Session paths      -> String contains check (source_path not indexed)\n2. Deduplication      -> (source_id, normalized_content) grouping\n3. Tool noise filter  -> Regex check for tool invocation markers\n```\n\n### Structured Filters\n```rust\npub struct SearchFilters {\n  agents: HashSet<String>,                // Agent slugs to include\n  workspaces: HashSet<String>,            // Workspace paths to include\n  created_from: Option<i64>,              // Start timestamp (ms)\n  created_to: Option<i64>,                // End timestamp (ms)\n  source_filter: SourceFilter,            // Local/Remote/SourceId\n  session_paths: HashSet<String>,         // For chained searches\n}\n\npub enum SourceFilter {\n  All,                                    // No filtering\n  Local,                                  // Only local sources\n  Remote,                                 // Only remote (SSH) sources\n  SourceId(String),                       // Specific source ID\n}\n```\n\n---\n\n## 8. DEDUPLICATION STRATEGY\n\n### Content-based Deduplication\n```rust\nfn deduplicate_hits(hits: Vec<SearchHit>) -> Vec<SearchHit> {\n  // Key: (source_id, normalized_content)\n  // normalized_content = split_whitespace + join(\" \")\n  \n  // Logic:\n  //   Same content from SAME source -> Keep highest score\n  //   Same content from DIFFERENT sources -> Keep both (P2.3 - source boundary)\n  \n  // Side effect: Filters tool invocation noise\n  //   Pattern: [Tool: X - description]\n}\n```\n\n### Source Boundary Respect (P2.3)\n```rust\n// Different sources = different conversations\n// Same content from local and SSH sources appear separately\n// Maintains clear source attribution\n```\n\n---\n\n## 9.

PERFORMANCE CHARACTERISTICS\n\n### Typical Latencies\n```\nPrefix queries (cached):           <5ms\nTerm queries (indexed):            5-50ms\nPhrase queries:                    20-100ms\nWildcard queries (prefix):         50-200ms\nWildcard queries (suffix regex):   100-500ms\nRange queries (time filter):       10-100ms\nFull-text complex (AND/OR/NOT):    50-500ms\nSemantic search:                   100-1000ms (embedding inference)\nHybrid (RRF):                      100-1500ms (both engines + fusion)\n```\n\n### Memory Usage Optimization\n```\nF16 quantization:  50% reduction vs F32\nEdge n-grams:      ~20-30% index size overhead for fast prefix matching\nMemory-mapped:     OS cache management (no heap allocation)\nLRU cache:         Bounded by configurable limits\n```\n\n### Scalability\n```\nDocuments indexed:    Millions (Tantivy designed for scale)\nSegment count:        Auto-merged when >= 4 (cooldown: 5min)\nQuery complexity:     Boolean expressions with arbitrary nesting\nConcurrent searches:  Multi-threaded Tokio runtime\n```\n\n---\n\n## 11. KEY OPTIMIZATION DECISIONS\n\n1. **Custom CVVI Format** instead of vector DB:\n   - Direct memory-mapped binary format\n   - Row-oriented for cache locality\n   - Content hash for deduplication\n   - No external dependencies\n\n2. **Prefix Cache** over full result set cache:\n   - Smaller memory footprint\n   - Bloom filter gates prevent false reuse\n   - Better for typing scenarios (incremental queries)\n\n3. **Warm Worker** for lazy index loading:\n   - Doesn't block user input\n   - Debounced to prevent thrashing\n   - OS cache prefill reduces latency spike\n\n4. **Source boundary** in deduplication:\n   - Maintains provenance clarity\n   - Different sources = different conversations\n   - Prevents losing context from multiple sources\n\n5. **Post-search filtering**:\n   - Session paths not indexed (too sparse)\n   - Applied after Tantivy retrieval\n   - Preserves index efficiency\n\n6. **Edge n-grams** for prefix matching:\n   - Avoids regex overhead for common case\n   - Leverages fast term matching\n   - No scanning needed\n\n---\n\n## 12. QUERY EXAMPLE WALKTHROUGH\n\n### Query: `rust async AND (tokio OR futures) NOT deprecated`\n\n```\n1. PARSING\n   Input: \"rust async AND (tokio OR futures) NOT deprecated\"\n   Tokens: [Term(\"rust\"), Term(\"async\"), Bool(AND), \n            Group(Term(\"tokio\"), Bool(OR), Term(\"futures\")), \n            Bool(NOT), Term(\"deprecated\")]\n\n2. CLAUSE BUILDING\n   Must clauses:\n   - rust     → [title_should, content_should, title_prefix_should, content_prefix_should]\n   - async    → [title_should, content_should, title_prefix_should, content_prefix_should]\n   - (tokio OR futures) → [BoolQuery([tokio_should, futures_should])]\n   \n   MustNot clause:\n   - deprecated → [title_should, content_should]\n\n3. FILTER APPLICATION\n   (assuming filters provided)\n   - agent: \"claude\" → TermQuery(\"claude\")\n   - workspace: \"/home/user/project\" → TermQuery(\"/home/user/project\")\n   - time range: created_from=1700000000, created_to=1700086400 → RangeQuery\n\n4. TANTIVY EXECUTION\n   searcher.search(\n     BooleanQuery([\n       (MUST, BoolQuery([rust_shoulds])),\n       (MUST, BoolQuery([async_shoulds])),\n       (MUST, BoolQuery([(OR, tokio_shoulds), (OR, futures_shoulds)])),\n       (MUSTNOT, BoolQuery([deprecated_shoulds])),\n       (MUST, TermQuery(\"claude\")),\n       (MUST, TermQuery(\"/home/user/project\")),\n       (MUST, RangeQuery(created_at))\n     ]),\n     &TopDocs::with_limit(limit).and_offset(offset)\n   )\n\n5. SCORING\n   BM25 scoring on matching documents:\n   - Term frequency in field\n   - Inverse document frequency\n   - Field weights (title > content)\n   - Boost for multiple matching terms\n\n6. SNIPPET GENERATION\n   SnippetGenerator creates context snippets with highlighted matches:\n   \"...in Rust, the **async** keyword with **tokio** runtime...\"\n\n7. RESULT ASSEMBLY\n   SearchHit {\n     title: \"Working with async/await in Rust\",\n     snippet: \"...**async** keyword with **tokio** runtime...\",\n     content: \"Full message content...\",\n     score: 15.73,\n     agent: \"claude\",\n     workspace: \"/home/user/project\",\n     created_at: 1700043200000,\n     match_type: Boolean,\n     ...\n   }\n```\n\n---\n\n## 13. ARCHITECTURAL STRENGTHS\n\n1. **Deterministic** - Same query always produces same results\n2. **Offline-first** - No external service calls for lexical search\n3. **Composable** - Lexical + semantic can be mixed via RRF\n4. **Progressive** - Gracefully degrades (hash embedder fallback)\n5. **Auditable** - Provenance fields track source of all results\n6. **Responsive** - Multi-layer caching for fast interactivity\n7. **Maintainable** - Clear separation: Tantivy (lexical), Vector (semantic), SQLite (metadata)\n\n---\n\n## SUMMARY TABLE\n\n| Pattern | Technology | Speed | Memory | Use Case |\n|---------|-----------|-------|--------|----------|\n| Prefix matching | Edge n-grams + TermQuery | <50ms | Minimal | Typing autocomplete |\n| Full-text | Tantivy BM25 | 5-100ms | Index size | Keyword search |\n| Phrase | Tantivy PhraseQuery | 20-100ms | Index size | Exact sequence |\n| Boolean | Tantivy BooleanQuery | 50-500ms | Query-size | Complex expressions |\n| Time filter | RangeQuery | 10-100ms | Minimal | Date-based filtering |\n| Semantic | FastEmbed + Vector | 100-1000ms | ~Vector size | Concept matching |\n| Hybrid | RRF fusion | 100-1500ms | ~Both sizes | Best of both |\n| Caching | LRU Bloom filter | <5ms | Bounded | Interactive typing |\n| Dedupe | HashMap | <1ms | Minimal | Noise filtering |\n\n"

    "content": "# CASS Quick Reference (Agent Quickstart + Performance)\n\n## Agent Quickstart (Robot Mode)\n\n⚠️ NEVER run bare `cass` in an agent context — it launches the TUI. Always use `--robot` or `--json`.\n\n```bash\n# Health + index\ncass health --json || cass index --full\n\n# Search (minimal payload for LLMs)\ncass search \"auth error\" --robot --limit 5 --fields minimal\n\n# Inspect a hit (use source_path + line_number from search output)\ncass view /path/to/session.jsonl -n 42 --json\ncass expand /path/to/session.jsonl -n 42 -C 3 --json\n\n# Machine-readable help\ncass robot-docs guide\ncass robot-docs schemas\n```\n\n**Key flags**\n- `--robot` / `--json`: machine-readable output (stdout only)\n- `--fields minimal`: lowest-token payload\n- `--limit N`: cap results\n- `--agent NAME`: filter (claude, codex, cursor, gemini, aider, etc.)\n- `--days N`: recent window\n\n---\n\n## TL;DR: What Makes CASS Fast\n\nCASS achieves **sub-10ms** interactive search through a 6-layer optimization strategy:\n\n1. **Prefix Cache** (LRU + 64-bit Bloom filter) → <5ms cache hits\n2. **Edge N-grams** (pre-computed term prefixes) → Fast prefix matching\n3. **Warm Worker** (background index reload) → Pre-paged OS cache\n4. **Segment Merging** (automatic on 4+ segments) → Fewer segments to search\n5. **Schema Versioning** → Automatic rebuild on schema mismatch\n6. **Lazy Semantic** → Optional, graceful fallback (hash-based embedder)\n\n---\n\n## Search Architecture Stack\n\n```\nUser Query\n    ↓\nParse & Optimize\n    ↓\nCheck Prefix Cache ← [HIT:

(tokenized) | Full-text search | BM25 scoring |\n| content | TEXT (tokenized) | Full-text search | BM25 scoring |\n| title_prefix | EDGE N-GRAM | Prefix matching | Fast term query |\n| content_prefix | EDGE N-GRAM | Prefix matching | Fast term query |\n| agent | STRING (single token) | Exact matching | TermQuery (no tokenization) |\n| workspace | STRING (single token) | Exact matching | TermQuery (no tokenization) |\n| created_at | I64 (FAST flag) | Range filtering | RangeQuery |\n| source_id | STRING | Provenance tracking | TermQuery |\n\n---\n\n## Performance Lookup Table\n\n| Pattern | Speed | Implementation |\n|---------|-------|-----------------|\n| Cached prefix | <5ms | LRU + Bloom64 gate |\n| Term query (indexed) | 5-50ms | Direct inverted index |\n| Phrase query | 20-100ms | Position index |\n| Prefix wildcard (foo*) | 50-200ms | Edge n-gram term |\n| Suffix wildcard (*foo) | 100-500ms | RegexQuery scan |\n| Boolean complex | 50-500ms | BooleanQuery nesting |\n| Time range filter | 10-100ms | RangeQuery |\n| Semantic search | 100-1000ms | FastEmbed inference |\n| Hybrid (RRF) | 100-1500ms | Dual execution |\n\n---\n\n## Caching Strategy\n\n### Prefix Cache Mechanism\n```\nUser types: \"h\"     → Search + Cache result (hits: [doc1, doc2, ...])\nUser types: \"he\"    → Filter cached hits via Bloom gate\nUser types: \"hel\"   → Refine from cache, still valid\nUser types: \"hello\" → Still matches cached results (all tokens present)\nUser deletes: \"hell\"→ Re-search (new cache entry)\n```\n\n### Cache Key Components\n```\nversion | schema_hash | query | agents | workspaces | time_range | source_filter | session_paths\n```\n\n### Hit Rate\n- **Interactive typing**: 60-80% (incremental queries reuse prefix results)\n- **Manual search**: 30-50% (depends on filter variation)\n\n---\n\n## Filtering Pipeline\n\n### Pre-Search (Index-aware)\nApplied as MUST clauses in BooleanQuery:\n- **Agents**: TermQuery on `agent` field (STRING/exact)\n- **Workspaces**: TermQuery on `workspace` field (STRING/exact)\n- **Time Range**: RangeQuery on `created_at` field (I64/FAST)\n- **Source**: TermQuery on `origin_kind` (local/ssh)\n\n### Post-Search (Content-aware)\nApplied after document retrieval:\n- **Session Paths**: String contains check (source_path not indexed)\n- **Deduplication**: Group by (source_id, normalized_content), keep max score\n- **Noise Filtering**: Regex check for tool invocations `[Tool: ...]`\n\n---\n\n## RRF (Reciprocal Rank Fusion) Formula\n\nUsed in Hybrid search mode to combine lexical + semantic results:\n\n```\nscore = Σ (1 / (K + rank))\n\nwhere:\n  K = 60 (constant, tunable)\n  rank = position in result list (0-indexed)\n```\n\n**Example:**\n```\nLexical results: [DocA@0, DocB@1, DocC@2]\nSemantic results: [DocA@0, DocD@1, DocB@2]\n\nRRF scores:\n  DocA: 1/(60+0) + 1/(60+0) = 0.0333 (highest - appears in both)\n  DocB: 1/(60+1) + 1/(60+2) = 0.0309\n  DocC: 1/(60+2)           = 0.0161\n  DocD: 1/(60+1)           = 0.0163\n\nFinal ranking: DocA > DocB > DocD > DocC\n```\n\n---\n\n## Bloom Filter Gate (64-bit)\n\nFast pre-check to prevent false reuse of cached results:\n\n```rust\n// Hash each token to 1 of 64 bits\nfor token in query.tokens {\n  bit_position = hash(token) % 64;\n  bloom64 |= (1 << bit_position);\n}\n\n// Check: all query tokens must have bits set in cached hit\nbool valid = (cached_hit.bloom64 & query.bloom64) == query.bloom64\n```\n\n**Benefits:**\n- Fast gate before expensive string matching\n- False positives possible (worst case: re-search)\n- False negatives impossible (always catches misses)\n\n---\n\n## Edge N-gram Generation\n\nPre-computed prefix matching without regex:\n\n```\nWord: \"async\"\n\nN-grams:\n  Length 2: \"as\"\n  Length 3: \"asy\"\n  Length 4: \"asyn\"\n  Length 5: \"async\"\n\nStorage: All 4 n-grams in `title_prefix` or `content_prefix` field\n\nQuery: \"asy*\"\n  → TermQuery for \"asy\" in title_prefix field\n  → 50-100ms (fast term match, no regex scan)\n```\n\n---\n\n## Schema Versioning\n\nAutomatic detection + rebuild:\n\n```\nSCHEMA_HASH = \"tantivy-schema-v6-provenance-indexed\"\n\nOn startup:\n  1. Read schema_hash.json from index\n  2. Compare to current SCHEMA_HASH\n  3. Mismatch? Delete & rebuild entire index\n  \nThis prevents subtle field-ID mismatches.\n```\n\n---\n\n## Custom CVVI Format (Vector Index)\n\nBinary format for semantic search vectors:\n\n```\nHeader (variable):\n  Magic:             \"CVVI\" (4 bytes)\n  Version:           u16\n  EmbedderID:        string\n  EmbedderRevision:  string\n  Dimension:         u32\n  Quantization:      u8 (0=F32, 1=F16)\n  Count:             u32\n  HeaderCRC32:       u32\n\nRows (70 bytes each):\n  MessageID:    u64\n  CreatedAtMs:  i64\n  AgentID:      u32\n  WorkspaceID:  u32\n  SourceID:     u32\n  Role:         u8 (user/assistant/system/tool)\n  ChunkIdx:     u8 (0 for single-chunk)\n  VecOffset:    u64 (offset in vector slab)\n  ContentHash:  [u8; 32] (SHA256)\n\nVector Slab:\n  All vectors concatenated, 32-byte aligned\n  Each component: F32 (4 bytes) or F16 (2 bytes)\n```\n\n**Advantages:**\n- No external vector DB dependency\n- Memory-mapped for efficient access\n- Content-addressed dedup (SHA256)\n- F16 quantization saves 50% memory\n\n---\n\n## Warm Worker (Background Optimization)\n\nProactive index page loading:\n\n```\nUser stops typing for 300ms\n  ↓\nWarm worker triggers (debounced MPMC channel)\n  ↓\nBackground tokio task:\n  1. Call reader.reload() (no-op if fresh)\n  2. Run mini search (limit: 1 doc) to page in OS cache\n  3. Record reload metrics\n  ↓\nNext user search benefits from hot OS cache\n```\n\n**Non-blocking:** Doesn't delay user input\n\n---\n\n## Segment Merging (Auto-Optimization)\n\nTantivy index fragmentation management:\n\n```\nSegments accumulate during indexing:\n  Segment 1 (100 docs)\n  Segment 2 (200 docs)\n  Segment 3 (150 docs)\n  Segment 4 (180 docs)  ← Threshold hit (4 segments)\n\nMerge triggered:\n  - Only if >= 4 segments AND 5 minutes since last merge\n  - Runs asynchronously in background\n  - Reduces per-query cost (fewer segments to search)\n  - No user-facing latency\n```\n\n---\n\n## Dependencies (Core)\n\n```toml\ntantivy = \"*\"              # Full-text search engine (BM25)\nfastembed = \"*\"            # ML embeddings (MiniLM)\nlru = \"*\"                  # LRU cache for prefix reuse\nhalf = \"*\"                 # F16 quantization\nmemmap2 = \"*\"              # Memory-mapped vectors\ntokio = \"*\"                # Async runtime (warm worker)\nrusqlite = \"*\"             # SQLite (metadata/fallback)\n```\n\n---\n\n## Common Queries & Their Execution Paths\n\n### Simple Term: `\"rust\"`\n```\nParse: token(\"rust\")\n  ↓\nCheck prefix cache: \"r\", \"ru\", \"rus\", \"rust\"\n  ↓\nBuild clauses: Must(BoolQuery([\n    Should(TermQuery(title, \"rust\")),\n    Should(TermQuery(content, \"rust\")),\n    Should(TermQuery(title_prefix, \"rust\")),\n    Should(TermQuery(content_prefix, \"rust\"))\n  ]))\n  ↓\nTantivy BM25 scoring\n  ↓\nSpeed: 5-50ms (cached) or 20-100ms (uncached)\n```\n\n### Phrase: `\"async await\"`\n```\nParse: phrase(\"async await\")\n  ↓\nSkip prefix cache (phrase not prefix-friendly)\n  ↓\nBuild: PhraseQuery with position index\n  ↓\nTantivy phrase matching\n  ↓\nSpeed: 20-100ms\n```\n\n### Wildcard: `\"rust*\"`\n```\nParse: wildcard(prefix, \"rust\")\n  ↓\nBuild: TermQuery on title_prefix/content_prefix with \"rust\" → \"rust\" (full word)\n  ↓\nSpeed: 50-200ms (edge n-gram term, not regex)\n```\n\n### Wildcard: `\"*async\"`\n```\nParse: wildcard(suffix, \"async\")\n  ↓\nCan't use edge n-grams (suffix doesn't align)\n  ↓\nBuild: RegexQuery for /.*async/\n  ↓\nTantivy regex scan\n  ↓\nSpeed: 100-500ms (more expensive)\n```\n\n### Boolean: `\"rust AND (tokio OR futures)\"`\n```\nParse: term(\"rust\") AND (term(\"tokio\") OR term(\"futures\"))\n  ↓\nBuild: Must([\n    Must(BoolQuery([rust_shoulds])),\n    Must(BoolQuery([(Should, tokio_shoulds), (Should, futures_shoulds)]))\n  ])\n  ↓\nTantivy boolean execution\n  ↓\nSpeed: 50-500ms (complex nesting)\n```\n\n### With Filters: `\"rust\" agent:claude workspace:\"/home/user\"`\n```\nParse query + filters\n  ↓\nBuild clauses:\n  Must([\n    query_clauses,\n    TermQuery(agent=\"claude\"),\n    TermQuery(workspace=\"/home/user\")\n  ])\n  ↓\nTantivy executes combined query\n  ↓\nSpeed: 20-100ms (filters pre-narrow before text search)\n```\n\n---\n\n## Deduplication Logic\n\nGroups identical content within a source, keeps highest-scored:\n\n```rust\nKey: (source_id, normalized_content)\n\nExample:\n  Hit 1: source=\"local\",  content=\"foo bar\", score=5.0\n  Hit 2: source=\"local\",  content=\"foo bar\", score=3.0  ← Dropped\n  Hit 3: source=\"ssh\",    content=\"foo bar\", score=4.0  ← Kept (different source)\n\nResult: 2 hits (P2.3: respect source boundaries)\n```\n\n---\n\n## Testing Strategy\n\nKey test patterns found in `tests/`:\n\n- `concurrent_search.rs` - Multi-threaded query safety\n- `semantic_integration.rs` - Embedder + vector index\n- `search_filters.rs` - Filter application\n- `ranking.rs` - RRF fusion verification\n- `search_caching.rs` - Prefix cache behavior\n- `e2e_search_index.rs` - End-to-end workflows\n\n---\n\n## Quick Wins for Similar Projects\n\n1. **Use edge n-grams** instead of regex for prefix matching\n2. **Cache partial results** (prefix + Bloom filter gate) instead of full sets\n3. **Separate pre/post filters** - index what you can, filter after if needed\n4. **Schema versioning** - catch breaking changes automatically\n5. **Background warm worker** - don't block on first user search\n6. **RRF fusion** - deterministic way to combine dual rankings\n7. **Content-addressed dedup** - normalize before grouping\n\n---\n\n## File Locations\n\n```\n/data/projects/coding_agent_session_search/\n├── CASS_SEARCH_PATTERNS.md           ← Detailed technical reference (this file)\n├── CASS_ARCHITECTURE_SUMMARY.txt     ← Visual architecture overview\n├── QUICK_REFERENCE.md                ← This quick reference card\n└── src/search/\n    ├── query.rs                      ← 6583 lines: SearchClient, caching, RRF\n    ├── tantivy.rs                    ← Index mgmt, schema, merging\n    ├── vector_index.rs               ← CVVI format, semantic filtering\n    ├── embedder.rs                   ← Embedder trait\n    ├── fastembed_embedder.rs         ← ML embeddings\n    └── hash_embedder.rs              ← Hash-based fallback\n```\n\n---\n\n## Further Reading\n\n- **Tantivy docs**: https://docs.rs/tantivy/\n- **FastEmbed docs**: https://github.com/qdrant/fastembed\n- **RRF paper**: https://dl.acm.org/doi/10.1145/312624.312649\n- **BM25 algorithm**: https://en.wikipedia.org/wiki/Okapi_BM25\n"

Read QUICK_REFERENCE.md \"TL;DR\" section\n2. Skim CASS_ARCHITECTURE_SUMMARY.txt \"SEARCH ARCHITECTURE LAYERS\"\n3. Look up your query type in QUICK_REFERENCE.md \"Common Queries\"\n\n### For Implementation (2-3 hours)\n1. Read QUICK_REFERENCE.md entirely\n2. Study CASS_SEARCH_PATTERNS.md sections 1-5 (architecture, indexing, queries)\n3. Review CASS_SEARCH_PATTERNS.md section 11 (key decisions)\n\n### For Deep Mastery (4-6 hours)\n1. Read all three documents thoroughly\n2. Study query.rs source code (6583 lines) focusing on:\n   - SearchClient implementation\n   - search_tantivy() function\n   - Prefix cache + Bloom filter\n   - RRF fusion\n   - Deduplication\n3. Study tantivy.rs for schema and tokenization\n\n---\n\n## Performance Summary\n\n### Typical Latencies\n```\nCached prefix search:     <5ms\nTerm query (indexed):     5-50ms\nPhrase query:             20-100ms\nPrefix wildcard (foo*):   50-200ms\nSuffix wildcard (*foo):   100-500ms\nBoolean complex:          50-500ms\nTime range filter:        10-100ms\nSemantic search:          100-1000ms\nHybrid (RRF):             100-1500ms\n```\n\n### Cache Hit Rates\n- Interactive typing: 60-80% (incremental prefix reuse)\n- Manual search: 30-50% (filter variation)\n\n### Memory Efficiency\n- F16 quantization: 50% reduction vs F32\n- Edge n-grams: +20-30% index overhead\n- LRU cache: Bounded by configurable limits\n\n---\n\n## Architecture Highlights\n\n### 6 Optimization Layers\n\n1. **Prefix Cache** (LRU + Bloom64) - <5ms cache hits\n2. **Edge N-grams** - Fast prefix matching without regex\n3. **Warm Worker** - Background index reload for OS cache\n4. **Segment Merging** - Auto-optimize when 4+ segments\n5. **Schema Versioning** - Automatic rebuild on mismatch\n6. **Lazy Semantic** - Optional, graceful fallback\n\n### 3 Search Engines\n\n1. **Tantivy** (Primary) - Full-text BM25 indexing\n2. **Vector Index** (Secondary) - Custom CVVI format embeddings\n3. **SQLite** (Tertiary) - Metadata fallback\n\n### 3 Search Modes\n\n1. **Lexical** - Keyword/BM25 matching\n2. **Semantic** - Embedding similarity\n3. **Hybrid** - RRF fusion of both\n\n---\n\n## Common Questions\n\n### Q: How fast is CASS search?\n**A:** <5ms for cached prefix queries, 5-100ms for typical term queries, up to 500ms for complex patterns.\n\n### Q: Why use edge n-grams instead of regex?\n**A:** Edge n-grams use fast Tantivy term matching (5-50ms) vs regex scanning (100-500ms).\n\n### Q: How does prefix caching work with multiple words?\n**A:** Only works for prefix-matching queries (no wildcards or boolean). Bloom filter gates prevent false reuse.\n\n### Q: What's RRF and why is it deterministic?\n**A:** Reciprocal Rank Fusion combines lexical + semantic rankings. Deterministic because same input always produces same score.\n\n### Q: Can I use these patterns in my project?\n**A:** Yes! See \"Quick Wins for Similar Projects\" in QUICK_REFERENCE.md\n\n---\n\n## Dependencies\n\n### Search Engines\n- **tantivy** - Full-text indexing with BM25\n- **fastembed** - ML embeddings (MiniLM)\n\n### Caching & Performance\n- **lru** - LRU cache for prefix reuse\n- **parking_lot** - Fast synchronization\n- **crossbeam-channel** - Multi-producer channels\n\n### Vector Operations\n- **half** - F16 quantization\n- **memmap2** - Memory-mapped vectors\n\n### Async/Runtime\n- **tokio** - Async runtime for warm worker\n\n### Persistence\n- **rusqlite** - SQLite integration\n\n---\n\n## Testing\n\nKey test files in `/data/projects/coding_agent_session_search/tests/`:\n\n- **concurrent_search.rs** - Multi-threaded safety\n- **search_caching.rs** - Prefix cache behavior\n- **semantic_integration.rs** - Embedder + vectors\n- **search_filters.rs** - Filter application\n- **ranking.rs** - RRF verification\n- **e2e_search_index.rs** - End-to-end workflows\n\n---\n\n## References\n\n### External Documentation\n- [Tantivy Docs](https://docs.rs/tantivy/)\n- [FastEmbed GitHub](https://github.com/qdrant/fastembed)\n- [RRF Paper](https://dl.acm.org/doi/10.1145/312624.312649)\n- [BM25 Wikipedia](https://en.wikipedia.org/wiki/Okapi_BM25)\n\n### Internal Documentation\n- `/data/projects/coding_agent_session_search/README.md` - Project overview\n- `/data/projects/coding_agent_session_search/AGENTS.md` - Agent integration\n\n---\n\n## Document Maintenance\n\n**Last Updated:** 2026-01-07\n\nThese documents are based on code analysis of CASS at commit `1640612` (\"let there be code\").\n\n### Document Generation\nAll three documents were programmatically generated from source code analysis:\n- Schema extracted from `/src/search/tantivy.rs`\n- Query logic from `/src/search/query.rs` (6583 lines)\n- Vector format from `/src/search/vector_index.rs`\n- Performance characteristics from code comments and test patterns\n\n### Keeping Documentation Updated\nWhen CASS code changes, update these sections:\n- **QUICK_REFERENCE.md** \"Performance Lookup Table\" - if latencies change\n- **CASS_SEARCH_PATTERNS.md** \"Schema Definition\" - if fields added/removed\n- **CASS_ARCHITECTURE_SUMMARY.txt** - if architecture layers change\n\n---\n\n## Contact & Contribution\n\nFor questions about these patterns or to suggest improvements:\n- See `/data/projects/coding_agent_session_search/README.md`\n- Review `/data/projects/coding_agent_session_search/TESTING.md` for test patterns\n\n"

    "content": "# TUI Interaction Model & Keymap RFC (cass)\n\nStatus: draft  \nOwner: RedHill  \nRelated issues: coding_agent_session_search-2noh9.1.4, coding_agent_session_search-2noh9.1.5, coding_agent_session_search-2noh9.2.2\n\n## Principles\n- Keyboard-first; mouse optional, never required.\n- Consistency: same chord does the same thing across panes; avoid mode confusion.\n- Discoverability: contextual help strip + command palette make actions findable.\n- Safety: no destructive actions without confirmation; ESC always exits modals/search.\n- Terminal resilience: graceful degradation on limited key support (esp. Ctrl+arrows, function keys).\n\n## Global Keymap\n- `Ctrl+P` — Command palette (fuzzy actions)\n- `?` — Quick tour / help overlay\n- `F1` — Toggle help strip pin/unpin (if available)\n- `Esc` — Close modal/overlay; clear inline searches; cancel prompts\n- `Tab` / `Shift+Tab` — Cycle focus panes (search → results → detail → footer/help)\n- `Ctrl+S` — Save view (see Saved Views)\n- `Ctrl+R` — Reload index/view state (non-destructive)\n- `F12` — Cycle ranking mode (recent / balanced / relevance / quality)\n- `Ctrl+B` — Toggle rounded/plain borders\n- `D` — Cycle density (Compact/Cozy/Spacious)\n- `g` / `G` — Jump to top/bottom of list\n- `PageUp/PageDown` or `Ctrl+U/Ctrl+D` — Scroll results pane by page\n\n## Search Bar\n- Direct typing — live query\n- `Up/Down` — Navigate query history\n- `Ctrl+L` — Clear search query\n- `Ctrl+W` — Delete last token\n- `Enter` — Run search immediately (forces query even during debounce)\n- `Ctrl+F` — Toggle wildcard fallback indicator (UI only; does not change query)\n\n## Filters & Pills\n- `F3` — Agent filter picker\n- `F4` — Workspace filter picker\n- `F5` — Time filter cycle (today/week/30d/all)\n- `F6` — Custom date range prompt\n- `F10` — Ranking mode cycle (alias of F12 if function keys limited)\n- In pills: `Enter` to edit, `Backspace` to remove, `Left/Right` to move between pills\n- Mouse: click pill to edit/remove\n\n## Results Pane\n- `Up/Down` — Move selection\n- `Enter` — Open drill-in modal (thread view)\n- `m` — Toggle multi-select\n- `Space` — Peek XL context (tap again to restore)\n- `A` — Bulk actions menu (open all, copy paths, export JSON, tag)\n- `/` — In-pane quick filter; `Esc` clears\n- `y` — Copy current snippet to clipboard\n- `o` — Open source file in $EDITOR\n- `v` — View raw source (non-interactive)\n- `r` — Refresh results (re-run query)\n\n## Detail Pane (Drill-In Modal)\n- `Left/Right` — Switch tabs (Messages / Snippets / Raw)\n- `c` — Copy path\n- `y` — Copy selected snippet\n- `o` — Open in $EDITOR\n- `f` — Toggle wrap in detail view\n- `Esc` — Close modal, return focus to results\n\n## Saved Views\n- `Ctrl+1..9` — Save current filters/ranking to slot\n- `Shift+1..9` — Recall slot\n- Toast confirms save/load; errors surface in footer\n\n## Density & Theme\n- `D` — Cycle density presets\n- `Ctrl+T` — Toggle theme (dark/light)\n- `F2` — Theme toggle (legacy alias)\n\n## Update Assistant\n- When banner shown: `U` upgrade, `s` skip this version, `d` view notes, `Esc` dismiss\n\n## Minimal / Robot Mode Behavior\n- When `TUI_HEADLESS=1` or stdout non-TTY: disable command palette, animation, icons; only allow `search`/`stats`/`view` via CLI.\n- Shortcut hints hidden; actions reachable via flags.\n\n## Fallbacks for Limited Key Support\n- If function keys unavailable: map F3/F4/F5/F6 to `Ctrl+3/4/5/6`.\n- If Ctrl+P conflicts: palette alias `Alt+P`.\n- If clipboard unsupported: `y` writes to temporary file path displayed in footer.\n\n## Mouse (optional)\n- Click focus between panes.\n- Scroll wheel scrolls results/detail.\n- Click pill to edit/remove; click breadcrumb to change scope.\n- Drag not required anywhere.\n\n## Safety / Destructive Actions\n- Bulk operations that open files only; no delete actions exist.\n- Any future destructive command must confirm via y/N prompt; default No.\n\n## Acceptance (coding_agent_session_search-002)\n- Keymap is conflict-free, discoverable (help strip + palette), and defined for degraded terminals.\n- ESC always backs out safely; no orphaned modal states.\n- Saved view, density, and theme toggles have keybindings and documented fallbacks.\n- Update assistant keys defined.\n\n## FrankenTUI Architecture Mapping (coding_agent_session_search-2noh9.1.4)\n\n### Core Mapping Table\n\n| Concern | Status | cass (ftui) | Implementation Notes |\n|---|---|---|---|\n| Terminal lifecycle | Done | `ftui_core::terminal_session::TerminalSession` + `SessionOptions` | Centralized startup/shutdown in one session owner; guarantees cleanup on panic/exit paths. |\n| Screen mode | Done | `ftui_runtime::ScreenMode::{Fullscreen, Inline { ui_height }}` + `UiAnchor` | Inline mode via `--inline` flag; fullscreen remains default. |\n| Render pipeline | Done | `ftui_render::Frame` -> `BufferDiff` -> `Presenter` | Deterministic diff-based rendering with Bayesian strategy selection. |\n| Event model | Done | `ftui_core::event::Event` consumed by `Program` update loop | All feature logic receives normalized ftui events via `CassMsg`. |\n| Runtime orchestration | Done | `ftui_runtime::{Program, Model, Cmd, Subscription}` | Side effects are explicit (`Cmd`) and composable; cancellation/debounce via runtime. |\n| Layout system | Done | `ftui_layout::{Flex, Grid, Constraint, LayoutSizeHint}` | Responsive layout with intrinsic sizing and explicit breakpoints. |\n| Widget primitives | Done | `ftui_widgets::{Widget, StatefulWidget}` + targeted built-ins | Built-ins used where available; cass-specific wrappers where needed. |\n| Command palette | Done | `ftui_widgets::command_palette` | Keybinding contract preserved, internals use standard widget. |\n| Help system | Done | `ftui_widgets::{help, help_registry, hint_ranker}` | Discoverability preserved with context ranking. |\n| Results virtualization | Done | `ftui_widgets::VirtualizedList` | Scales to large result sets with bounded render cost. |\n| Modal/toast stack | Done | `ftui_widgets::{modal, toast, notification_queue}` | ESC/back semantics preserved with standardized stack behavior. |\n| Focus traversal | Done | `ftui_widgets::focus::{FocusGraph, FocusManager}` | One focus graph for panes, modals, and command palette. |\n| Testing harness | Done | `ftui-harness` snapshots + `ProgramSimulator` + render traces | Snapshot and state-transition testing is primary path. |\n| Debug traceability | Done | `ftui_runtime::{render_trace, input_macro, AsciicastRecorder}` | Replayable traces for keyflow and rendering debugging. |\n\n### Widget Adoption Plan (Use Built-ins First)\n\n| Existing cass surface | Preferred ftui widget/module | Fallback if gap remains |\n|---|---|---|\n| Query/filter top bar | `input`, `group`, `status_line`, `help_registry` | Local wrapper in `src/ui/components` |\n| Results pane | `VirtualizedList`, `scrollbar`, `list` | Keep temporary local renderer until feature parity |\n| Detail pane | `paragraph`, `tree`, `json_view`, `log_viewer` | Local detail renderer while migrating tabs incrementally |\n| Bulk actions / menus | `command_palette`, `modal` | Local modal wrapper with same action contract |\n| Notifications | `toast` + `notification_queue` | Existing toast manager (temporary) |\n\n### Design Decisions (Locked for Migration)\n\n1. Use a single top-level `Model` with explicit sub-state enums rather than multiple independent runtime programs.\n2. Use `FocusGraph` as the authoritative focus-routing mechanism for `Tab`/`Shift+Tab` and modal focus restore.\n3. Keep current keybinding contract stable during migration; behavior changes must be explicit RFC updates.\n4. Use built-in ftui widgets for palette/help/modal/virtualized list whenever available; do not re-implement equivalents.\n5. Start with explicit state updates in `update()` and only adopt ftui reactive bindings in targeted areas where it reduces complexity.\n\n### Gap-Handling Policy\n\n- If a missing capability is generally reusable, upstream to FrankenTUI and consume via pinned git revision.\n- If the behavior is cass-specific, implement a thin local adapter/wrapper in cass.\n- Never block migration on \"perfect widget parity\" if a temporary local wrapper can preserve user behavior.\n- Record each gap as a bead linked to the owning migration epic, with explicit exit criteria.\n\n### Migration Execution Order\n\n1. Foundation (`2noh9.2.x`): dependency + runtime skeleton + terminal/session wiring. **Done.**\n2. Parity (`2noh9.3.x`): search/filter/results/detail/modals reimplemented on ftui. **Done.**\n3. Enhancements (`2noh9.4.x`): inline mode, traces, advanced UX, dashboards. **In progress.**\n4. QA and removal (`2noh9.5.x`, `2noh9.6.x`): test hardening, ratatui removed. **Ratatui fully removed (2noh9.6.1).**\n\n### Acceptance for This Mapping Bead\n\n- Mapping covers terminal lifecycle, screen modes, render pipeline, event model, layout, widgets, runtime, and testing hooks.\n- Includes explicit decisions for model structure, focus strategy, reactive usage, and built-in widget adoption.\n- Includes a concrete gap policy so implementation beads can proceed without reopening architecture debates.\n\n## Analytics Dashboard IA & Interaction Spec (coding_agent_session_search-2noh9.4.18.1)\n\nStatus: finalized draft  \nOwner: CoralLantern  \nRelated analytics beads: `z9fse.12`, `z9fse.6`, `z9fse.10`, `z9fse.11`  \nTime semantics: UTC-only for v1\n\n### Scope and Constraints\n\n- Defines a single interaction contract for ftui analytics surfaces so CLI + TUI semantics do not drift.\n- Uses rollup-first queries by default; deep/fact scans are explicit opt-in paths.\n- Requires full keyboard operation; mouse is an enhancement only.\n- Keeps existing search workflows central: analytics drilldown must jump into the main Search surface with pre-applied filters.\n\n### Information Architecture\n\nTop-level analytics entry points:\n\n- Command palette entries:\n  - `Analytics: Dashboard`\n  - `Analytics: Explorer`\n  - `Analytics: Heatmap`\n  - `Analytics: Breakdowns`\n  - `Analytics: Tools`\n  - `Analytics: Cost Models`\n  - `Analytics: Coverage`\n- Global hotkey: `Alt+A` (fallback `g a` chord)\n\nAnalytics subviews:\n\n| View | Primary Goal | Core Widgets | Primary Data Source |\n|---|---|---|---|\n| Dashboard | At-a-glance health and trend deltas | KPI tiles + sparklines + top movers | `usage_daily`, `token_daily_stats`, cost rollups |\n| Explorer | Time-series comparison and overlays | Line/area chart + overlay legend + cursor tooltip | rollups by bucket (hour/day/week/month) |\n| Heatmap | Calendar activity scan | Calendar heatmap + legend + day cursor | daily rollups |\n| Breakdowns | Ranked dimensions and trends | Virtualized sortable table + per-row sparkline | grouped rollups |\n| Tools | Tool usage efficiency | per-tool table + trend strip + jump action | `tool_usage_hourly/daily`, `tool_calls_detail` |\n| Cost Models | Model/provider spend behavior | stacked token/cost bars + model table | pricing + model rollups |\n| Coverage | Data quality visibility | coverage matrix + warning list | API coverage counters + connector health |\n\n### Layout and Minimum Terminal Sizes\n\n- Recommended: `>= 160x44` for full analytics layout with side panels.\n- Supported baseline: `>= 120x36` with compressed sidebars.\n- Narrow mode (`< 120 cols`): single-primary-pane with drawer overlays for filters and legend.\n- Hard minimum for reliable operation: `100x30`; below this, show inline \"expand terminal\" guidance.\n\n### Global Filters (Persisted While in Analytics)\n\nFilter ribbon (top) plus collapsible filter drawer (narrow mode):\n\n- Time range:\n  - presets: today, 7d, 30d, 90d, YTD, all\n  - custom: since/until\n- Agent: multi-select with fuzzy match\n- Workspace: multi-select with fuzzy match\n- Source: all/local/remote/source-id\n- Optional advanced: role filter for message role segmentation\n\nPersistence rules:\n\n- Analytics filters persist separately from general search ad hoc filters.\n- On leaving analytics and returning in the same session, previous analytics filter state is restored.\n- On app restart, last analytics filter state is restored from `tui_state.json`-compatible persistence.\n\n### Drilldown Semantics (Contract)\n\n- `Enter` on a chart point, heatmap day, or KPI delta opens Search view with inherited filters:\n  - time bucket mapped to `created_from/created_to`\n  - analytics agent/workspace/source selections applied\n  - query left empty by default\n- `Enter` on a breakdown row opens Search with inherited filters plus row dimension:\n  - examples: `agent=codex`, `workspace=<id>`, `tool_name=Read`\n- Drilldown always pushes a view-stack entry.\n- `Esc` returns to prior analytics view without losing filter context.\n\n### Keyboard Model\n\nGlobal within analytics:\n\n- `Tab` / `Shift+Tab`: cycle analytics subviews\n- `g`: open analytics-local \"go to view\" selector\n- `/`: open filter/search within the active analytics view\n- `Enter`: drilldown to Search\n- `Esc`: back (pop view stack)\n- `?`: analytics-context help overlay\n\nExplorer-specific:\n\n- `Left/Right`: move bucket cursor\n- `Up/Down`: cycle overlay dimension (agent/workspace/source/model)\n- `[` / `]`: previous/next metric\n\nBreakdowns-specific:\n\n- `s`: cycle sort column\n- `r`: reverse sort direction\n- `Space`: pin/unpin selected row for comparison\n\n### Command Palette Contract\n\nRequired command entries:\n\n- `Analytics: Dashboard`\n- `Analytics: Explorer`\n- `Analytics: Heatmap`\n- `Analytics: Breakdowns`\n- `Analytics: Tools`\n- `Analytics: Cost Models`\n- `Analytics: Coverage`\n- `Analytics: Reset Filters`\n- `Analytics: Jump to Search (Current Scope)`\n\n### Data Semantics and Definitions\n\n- All bucketing in v1 is UTC.\n- Week definition: ISO week (Mon-Sun).\n- Month definition: calendar month UTC.\n- Costs are marked as:\n  - measured (API cost data present)\n  - estimated (derived from pricing table)\n  - unavailable (insufficient metadata)\n- Coverage panel must disclose when metrics are partially estimated or stale.\n\n### Dependency Mapping to Analytics Beads\n\n| UI Capability | Dependency Bead | Why |\n|---|---|---|\n| Shared analytics query semantics across CLI/TUI | `z9fse.12` | prevents drift and duplicated logic |\n| Tool breakdown and trends | `z9fse.6` | provides per-tool rollups and fact linkage |\n| USD cost estimations and labels | `z9fse.10` | powers cost/cost-model surfaces |\n| Stable model attribution dimensions | `z9fse.11` | enables model/provider grouping consistency |\n\n### Snapshot and PTY Test Targets\n\nSnapshot targets (ftui-harness):\n\n- Dashboard default state with 30d preset\n- Explorer with agent overlay active\n- Heatmap with legend + selected day\n- Breakdowns sorted by descending tokens\n- Tools view with selected tool row and trend sparkline\n- Coverage matrix with at least one warning badge\n\nPTY e2e flow targets:\n\n- Launch TUI -> open analytics (`Alt+A`) -> switch Dashboard -> Explorer -> Heatmap.\n- Apply filters (time + agent + source) and verify ribbon state.\n- Perform drilldown with `Enter` and verify Search is scoped correctly.\n- Use `Esc` back-stack unwind and confirm prior analytics state restored.\n- Exit cleanly with no terminal corruption.\n\n### Acceptance Criteria\n\n- IA is explicit enough for implementation without reopening interaction design.\n- Keymap + command palette entries are specified and non-conflicting.\n- Drilldown behavior is deterministic and reversible (`Esc`).\n- Dependencies on `z9fse.12`, `.6`, `.10`, `.11` are explicit and actionable.\n- Test targets are concrete for both snapshot and PTY coverage.\n\n## Finalized Interaction Contract (coding_agent_session_search-2noh9.1.5)\n\n> Status: **finalized**\n> Audited against: `src/ui/tui.rs`, `src/ui/shortcuts.rs`, `src/ui/components/export_modal.rs`\n> Date: 2026-02-06\n\n---\n\n### 1.

Modal group nodes are removed from graph\n\n**Stack ordering (innermost = highest priority):**\n\n```\n[bottom] GROUP_MAIN\n         GROUP_HELP          (F1/?)\n         GROUP_PALETTE       (Ctrl+P)\n         GROUP_DETAIL_MODAL  (Enter on result)\n         GROUP_EXPORT        (e in detail)\n         GROUP_CONSENT       (semantic model prompt)\n         GROUP_BULK          (A key)\n         GROUP_SOURCE        (Shift+F11)\n[top]    (active prompt)\n```\n\nOnly the top group receives keyboard input. Background groups render but do not interact.\n\n#### 3.5 Focus Transitions (Concrete Examples)\n\n**Opening detail modal:**\n```\nState: focus = FOCUS_RESULTS, trap_stack = [GROUP_MAIN]\nUser presses Enter\n  -> push_trap(GROUP_DETAIL_MODAL)\n  -> focus = FOCUS_DETAIL_MODAL\n  -> trap_stack = [GROUP_MAIN, GROUP_DETAIL_MODAL]\n  -> Tab cycles within: [FOCUS_DETAIL_MODAL] only\n```\n\n**Opening export from within detail:**\n```\nState: focus = FOCUS_DETAIL_MODAL, trap_stack = [GROUP_MAIN, GROUP_DETAIL_MODAL]\nUser presses e\n  -> push_trap(GROUP_EXPORT)\n  -> focus = FOCUS_EXPORT_FORMAT (first field)\n  -> trap_stack = [GROUP_MAIN, GROUP_DETAIL_MODAL, GROUP_EXPORT]\n```\n\n**Closing export (Esc):**\n```\n  -> pop_trap() -> return_focus = FOCUS_DETAIL_MODAL\n  -> trap_stack = [GROUP_MAIN, GROUP_DETAIL_MODAL]\n```\n\n**Closing detail (Esc again):**\n```\n  -> pop_trap() -> return_focus = FOCUS_RESULTS\n  -> trap_stack = [GROUP_MAIN]\n```\n\n#### 3.6 Focus Flash Indicator\n\nOn focus change: render a 220ms highlight on the newly focused pane border.\nImplementation: `Cmd::tick(Duration::from_millis(220))` -> message clears flash state.\n\n---\n\n### 4. Modal and Overlay Semantics\n\n#### 4.1 Modal Stack Priority (rendering order, back-to-front)\n\n1. Main panes (SearchInput, Results, Detail) — always rendered\n2. Help overlay — renders over main, dims background\n3. Command palette — renders over everything below\n4. Detail drill-in modal — replaces detail pane area\n5. Export modal — renders over detail modal\n6. Source filter menu — dropdown overlay\n7. Bulk actions menu — centered modal\n8. Consent dialog — centered modal, highest non-prompt priority\n9. Active text prompt — inline within its parent modal\n\n#### 4.2 Input Routing\n\nOnly the **top-most overlay** receives keyboard input:\n- If consent dialog is open -> consent keys only\n- If export modal is open -> export keys only\n- If detail modal is open -> detail keys only (unless export is stacked)\n- If help overlay is open -> help scroll keys only\n- If command palette is open -> palette keys only\n- Otherwise -> main pane keys based on current focus\n\n#### 4.3 Background Rendering\n\nPanes below the active overlay continue rendering (results may update from async search).\nThey are visually dimmed to indicate non-interactivity.\n\n---\n\n### 5. ESC Unwind Contract\n\nOn `Esc`, unwind in this **exact priority order** until one action succeeds:\n\n1. **Cancel active text input** (filter input, palette search, export field, find query).\n2. **Close top-most modal** (pop_trap in FocusManager, restore prior focus).\n3. **Exit pane-local find/filter** mode (ResultsList or DetailPane).\n4. **Clear multi-select** if any items are selected.\n5. **Close detail pane** if open (return focus to Results).\n6. **Quit TUI session** if no pending state remains.\n\n`Ctrl+C` bypasses this chain entirely and force-quits immediately.\n\n---\n\n### 6. State Persistence (tui_state.json)\n\n**Location:** `~/.local/share/coding-agent-search/tui_state.json`\n\n**Persisted on change:**\n\n| Field | Type | Default |\n|---|---|---|\n| `search_mode` | `\"lexical\"` / `\"semantic\"` / `\"hybrid\"` | `\"lexical\"` |\n| `match_mode` | `\"standard\"` / `\"prefix\"` | `\"standard\"` |\n| `ranking_mode` | `\"recent\"` / `\"balanced\"` / `\"relevance\"` / `\"quality\"` / ... | `\"balanced\"` |\n| `context_window` | `\"small\"` / `\"medium\"` / `\"large\"` / `\"xlarge\"` | `\"medium\"` |\n| `theme_dark` | bool | `true` |\n| `density_mode` | `\"compact\"` / `\"cozy\"` / `\"spacious\"` | `\"cozy\"` |\n| `per_pane_limit` | usize (4..50) | `10` |\n| `query_history` | Vec<String> (max 50, deduplicated) | `[]` |\n| `saved_views` | Vec<SavedViewPersisted> (slots 1-9) | `[]` |\n| `fancy_borders` | bool | `true` |\n| `has_seen_help` | bool | `false` |\n\n**Reset:** `Ctrl+Shift+Del` deletes tui_state.json and resets all fields to defaults.\n\n**ftui integration:** Use `Cmd::SaveState` / `Cmd::RestoreState` for persistence lifecycle.\n\n---\n\n### 7. Headless / Robot Mode Constraints\n\nWhen `TUI_HEADLESS=1` or stdout is non-TTY:\n\n| Feature | Behavior |\n|---|---|\n| Terminal raw mode | **Disabled** — no raw mode setup |\n| Mouse capture | **Disabled** |\n| Alt-screen | **Disabled** |\n| Rendering / event loop | **Disabled** — exits after non-interactive operation |\n| Command palette | **Disabled** |\n| Modal animations | **Disabled** |\n| Decorative effects | **Disabled** |\n| Focus management | **Disabled** |\n| All interactive modals | **Disabled** |\n| State persistence | **Enabled** (`--reset-state` supported) |\n| CLI flag operations | **Enabled** (search, stats, view via flags) |\n\nFor ftui snapshot/smoke tests:\n- Use `ProgramSimulator` from ftui-harness\n- Keep deterministic render path\n- Overlay-only actions are no-ops unless explicitly invoked by test harness API\n\n---\n\n### 8. Degraded Terminal Fallbacks\n\n| Missing Feature | Fallback | Notes |\n|---|---|---|\n| Function keys (F1-F12) | `Ctrl+3/4/5/6` for F3-F6 filters; `Ctrl+T` for F2 theme; `?` for F1 help | |\n| `Ctrl+P` conflict (tmux) | `Alt+P` palette alias | |\n| Clipboard (no OSC 52) | `y` writes to temp file; path shown in footer toast | |\n| Narrow terminal (<80 cols) | Collapse visual affordances; hide help strip; preserve all keybindings | |\n| No Unicode support | Plain ASCII borders (`+`, `-`, `|`); no emoji in pills | Detected via `$TERM` |\n| No color support | Monochrome mode; bold/underline for emphasis | |\n\n---\n\n### 9. Mouse Behavior (Optional, Never Required)\n\n| Event | Region | Action |\n|---|---|---|\n| Left click | Pane header | Focus that pane |\n| Left click | Result item | Select item + show detail |\n| Left click | Detail area | Focus detail pane |\n| Left click | Filter pill | Edit pill value |\n| Left click | Breadcrumb | Change scope |\n| Scroll up/down | Results pane | Scroll result selection |\n| Scroll up/down | Detail pane | Scroll detail content |\n\n**Ignored when any modal is open** (help, palette, export, bulk, consent, source menu).\n\n**Drag:** Not required anywhere. No drag interactions.\n\n---\n\n### 10. Action System Contract\n\nEvery user action maps to a named action for palette registration and keybinding docs:\n\n| Action Name | Keys | Requires |\n|---|---|---|\n| `help.toggle` | `F1`, `?`, `Ctrl+?` | — |\n| `theme.toggle` | `F2`, `Ctrl+T` | — |\n| `filter.agent` | `F3` | — |\n| `filter.agent.scope` | `Shift+F3` | Selected result |\n| `filter.workspace` | `F4` | — |\n| `filter.agent.clear_scope` | `Shift+F4` | — |\n| `filter.date_from` | `F5` | — |\n| `filter.time_presets` | `Shift+F5` | — |\n| `filter.date_to` | `F6` | — |\n| `filter.clear_all` | `Ctrl+Del` | — |\n| `context_window.cycle` | `F7` | — |\n| `editor.open` | `F8`, `o` | Selected result |\n| `match_mode.cycle` | `F9` | — |\n| `source_filter.cycle` | `F11` | — |\n| `source_filter.menu` | `Shift+F11` | — |\n| `ranking.cycle` | `F12` | — |\n| `search_mode.cycle` | `Alt+S` | — |\n| `palette.open` | `Ctrl+P`, `Alt+P` | — |\n| `history.cycle` | `Ctrl+R` | History non-empty |\n| `history.next` | `Ctrl+n` | History non-empty |\n| `history.prev` | `Ctrl+p` | History non-empty |\n| `index.refresh` | `Ctrl+Shift+R` | — |\n| `state.reset` | `Ctrl+Shift+Del` | — |\n| `borders.toggle` | `Ctrl+B` | — |\n| `density.cycle` | `Ctrl+D` | — |\n| `view.save` | `Ctrl+1..9` | — |\n| `view.load` | `Shift+1..9` | Slot non-empty |\n| `result.select` | `Enter` | Result focused |\n| `result.peek` | `Space`, `Ctrl+Space` | Result focused |\n| `result.copy` | `y`, `Ctrl+Y` | Result focused |\n| `result.open` | `o` | Result focused |\n| `result.view_raw` | `v` | Result focused |\n| `result.refresh` | `r` | — |\n| `select.toggle` | `Ctrl+X` | Result focused |\n| `select.all` | `Ctrl+A` | — |\n| `select.enqueue` | `Ctrl+Enter` | Result focused |\n| `select.open_all` | `Ctrl+O` | Selection non-empty |\n| `bulk.menu` | `A` | Selection non-empty |\n| `export.quick` | `Ctrl+E` | Result focused |\n| `export.modal` | `e` | Detail open |\n| `detail.copy_content` | `c` | Detail open |\n| `detail.copy_path` | `p` | Detail open |\n| `detail.copy_snippet` | `s` | Detail open |\n| `detail.open_nano` | `n` | Detail open |\n| `detail.wrap` | `f` | Detail open |\n| `detail.tab_cycle` | `[`, `]` | Detail open |\n| `detail.find` | `/` | Detail focused |\n| `pane.filter` | `/` | Results focused |\n| `pane.grow` | `Shift+=` | — |\n| `pane.shrink` | `Alt+-` | — |\n| `nav.focus_next` | `Tab` | — |\n| `nav.focus_prev` | `Shift+Tab` | — |\n| `nav.top` | `Home`, `g` | — |\n| `nav.bottom` | `End`, `G` | — |\n| `nav.page_up` | `PageUp` | — |\n| `nav.page_down` | `PageDown` | — |\n| `app.quit` | `Esc`, `F10` | No pending state |\n| `app.force_quit` | `Ctrl+C` | Always |\n\n---\n\n### 11. Conflict Audit\n\n**Verified conflict-free within each context scope.** Key observations:\n\n- `/` is context-sensitive: in search bar focus = pane filter, in detail focus = find-in-detail. No conflict because they are different focus contexts.\n- `y` in results = copy snippet, `y` in detail = copy snippet. Same semantic, no conflict.\n- `g`/`G` for jump: only active when results/detail focused, not during text input. No conflict with filter char input.\n- `D` for density: only active in query mode, not consumed during filter text input modes.\n- `n` in detail = open nano, `n` in detail-find = next match. Different sub-contexts (find active vs not). No conflict.\n- `Ctrl+R`: history cycle in search, index refresh is `Ctrl+Shift+R`. Different modifiers, no conflict.\n\n---\n\n### Acceptance Criteria for This Bead\n\n- [x] Every shortcut in `src/ui/shortcuts.rs` is accounted for with keep/change rationale.\n- [x] All shortcuts discovered in `src/ui/tui.rs` implementation are documented (100+ bindings).\n- [x] No duplicate meaning exists for a shortcut within the same interaction context.\n- [x] Focus traversal mapped to ftui `FocusGraph` / `FocusManager` / `FocusGroup` with concrete IDs.\n- [x] Modal stack lifecycle (push_trap/pop_trap) is deterministic and documented.\n- [x] ESC unwind contract has explicit priority ordering.\n- [x] State persistence fields enumerated with defaults.\n- [x] Headless and degraded-terminal behaviors are explicit and testable.\n- [x] Action system named for palette registration and future keybinding customization.\n- [x] Conflict audit performed and no conflicts found.\n"

    "content": "# TUI Style System Spec (cass)\n\nStatus: draft  \nOwner: RedHill  \nScope: FrankenTUI (ftui) Elm-architecture UI (interactive + robot-safe fallbacks)\n\n## Goals\n- Make cass “instant, legible, delightful” without sacrificing low-end terminals.\n- Provide one source of truth for colors, spacing, motion, density, and icons.\n- Keep accessibility: high contrast, color is never the sole carrier of meaning.\n- Ensure every visual flourish has a performance and opt-out policy.\n\n## Color System\n\n### Base tokens\n- `bg`: #0f1115 (dark), #f8f9fb (light)\n- `bg-panel`: #161922 (dark), #ffffff (light)\n- `bg-muted`: #1c202a (dark), #f0f2f6 (light)\n- `fg`: #e6e9f2 (dark), #1b1f2a (light)\n- `fg-muted`: #a9b1c7 (dark), #51586b (light)\n- `accent`: #7aa2ff (blue), secondary #ffb86c (amber) for warnings\n- `border`: #2b3242 (dark), #d8dde7 (light)\n- `success`: #6bd49a, `warn`: #ffb86c, `error`: #ff6b6b, `info`: #7aa2ff\n\n### Role colors (gutter + label)\n- user: #7aa2ff\n- assistant: #8ef1c7\n- system: #c5b3ff\n- tool: #ffb86c\n- other/unknown: #94a3b8\n\n### Gradients (subtle 2-stop)\n- Header/pill active: `linear( accent 0%, accent*0.75 100% )`\n- Selection glow (optional): `accent 20% alpha` to `accent 0% alpha`\n- Never rely on gradients for legibility; text sits on solid overlays.\n\n### Contrast rules\n- Minimum contrast 4.5:1 for text; if terminal reports 8-color, fall back to high-contrast flat palette (no gradients, no alpha).\n- No-color mode: map to ANSI defaults; remove gradients and icons; keep layout.\n\n## Typography & Layout\n- Font assumption: terminal mono; use weight via color/spacing, not bold spam.\n- Title caps: Section headers use Title Case; pills use Sentence case.\n- Truncation: prefer middle-ellipsis for long paths; never wrap glyph icons alone.\n\n## Spacing & Sizing\n- Base unit: 2 chars.\n- Spacing scale: 0, 1 (2ch), 2 (4ch), 3 (6ch).\n- Border radius: small (1) when width >= 90 cols; square when narrower.\n- Card padding: Compact (1,1), Cozy (1,2), Spacious (2,3).\n\n## Density Presets\n- Compact: max 1 snippet line, tighter row height; default for 80x24.\n- Cozy (default): 2 snippet lines, standard padding.\n- Spacious: 3 snippet lines, extra line gap in detail pane.\n- Toggle key: `D`. Persist in config; auto-fallback to Compact if cols < 90.\n\n## Iconography\n- Glyph set (ASCII-safe fallbacks):\n  - agent: `@` (fallback), `󰚩` when supported\n  - file/snippet: `` fallback `[]`\n  - workspace: `` fallback `/`\n  - latency badge: `⏱`\n  - cache hit: `●`, miss: `○`\n- Icons always paired with text; hidden in no-color or minimal modes.\n\n## Motion\n- Default: staggered fade/slide for top 10 results, 90–120 ms, ease-out.\n- Disable via `CASS_ANIM=0` or minimal mode; auto-disable if fps < 45 or width < 80.\n- Never animate input latency; motion only on render transitions.\n\n## Components (visual rules)\n- Filter pills: rounded when wide; square when narrow; active uses gradient; inactive uses `bg-muted`; close/edit glyph on the right.\n- Breadcrumb bar: `Agent › Workspace › Date › Ranking`; each crumb uses muted text with active crumb accent underline.\n- Results list: alternating muted stripes + 1px role-colored gutter; snippet highlight bold; non-match lines dimmed.\n- Drill-in modal: solid backdrop (no blur); bordered panel with role gutters; footer for quick actions.\n- Footer HUD: left = help strip; middle = progress/indexer sparkline; right = latency/cache badges.\n- Empty states: icon + friendly copy + 3 quick buttons; must fit in 80x24.\n\n## Detail Find Bar Token Contract (2dccg.4.1)\n\n### Semantic tokens\n- `STYLE_DETAIL_FIND_CONTAINER` (`detail.find.container`): container surface for the inline find row in detail pane.\n- `STYLE_DETAIL_FIND_QUERY` (`detail.find.query`): active query text emphasis.\n- `STYLE_DETAIL_FIND_MATCH_ACTIVE` (`detail.find.match.active`): current match indicator (high-emphasis state).\n- `STYLE_DETAIL_FIND_MATCH_INACTIVE` (`detail.find.match.inactive`): total/secondary match count (low-emphasis state).\n\n### Part → token mapping\n- Find bar row container/background: `STYLE_DETAIL_FIND_CONTAINER`\n- Query text after `/`: `STYLE_DETAIL_FIND_QUERY`\n- Current match segment (`current/total` current portion): `STYLE_DETAIL_FIND_MATCH_ACTIVE`\n- Remaining match metadata (total, no-match state): `STYLE_DETAIL_FIND_MATCH_INACTIVE`\n\n### Theme and degradation expectations\n- Theme-aware: all four tokens derive from semantic theme palette (`surface`, `overlay`, `accent`, `selection_*`, `text_muted`) and therefore follow preset changes automatically.\n- `DegradationLevel::Full` / `SimpleBorders`: render full token styling (container background + emphasized query/current match).\n- `DegradationLevel::NoStyling` / `EssentialOnly`: rendering layer falls back to structural/plain text while preserving information order and keyboard behavior (`/`, `n`, `N`, `Esc`).\n\n### Contrast and focus guidance\n- Current match state must remain visually stronger than inactive match metadata.\n- Container background must be distinct from surrounding detail content in all presets.\n- Query emphasis must not rely on color alone (bold retained for emphasis in mono/high-contrast modes).\n\n## Accessibility & Resilience\n- Colorblind support: role gutters pair color with pattern (solid vs dotted vs dashed) in gutters when `CASS_A11Y=1`.\n- Mouse optional; all interactions keyboard-first.\n- Respect `NO_COLOR` / `CASS_NO_COLOR`; degrade to flat monochrome.\n- Headless/robot: suppress gradients, icons, motion; keep structure for tests.\n\n## Performance Guards\n- Highlighting: cap at 2 ms per snippet; fallback to plain when exceeded or cols < 100.\n- Animation budget: total frame < 16 ms on typical CPU; otherwise auto-disables.\n- Cache theme objects for reuse; avoid allocs in draw loop; precompute truncations.\n\n## Opt-out Matrix\n- Animations: `CASS_ANIM=0`\n- Gradients: `CASS_NO_GRADIENT=1`\n- Icons: `CASS_NO_ICONS=1`\n- Color: `NO_COLOR=1` or `CASS_NO_COLOR=1`\n- A11y patterns: `CASS_A11Y=1`\n- Minimal mode (tests/CI): `TUI_HEADLESS=1` or `--once` flows strip embellishments.\n\n## Persistence\n- Density, theme (dark/light), a11y, animation toggles, and gradient/icon flags persist in config file under data dir; defaults are safe for 80x24, 8-color.\n\n## Telemetry (local only)\n- If enabled, log render timing, highlight fallback counts, animation opt-out events to trace/log; no PII and disabled by default.\n\n## Acceptance checklist (BD-001)\n- Spec stored at `docs/tui_style_spec.md`.\n- Defines concrete tokens, spacing, motion budgets, opt-out flags.\n- Addresses accessibility (contrast + patterns) and low-end terminal fallback.\n- Provides guardrails for perf and persistence defaults.\n\n## Related docs\n- `docs/ftui_visual_parity_rubric.md` (deterministic release-gate scoring rubric for ratatui vs FTUI visual parity)\n"

Fuzz target for the FTS5 query transpiler (bead\n//! `coding_agent_session_search-ugp09`).\n//!\n//! `fuzz_query_parser.rs` already exercises `QueryExplanation::analyze`\n//! — the static introspection path. This target covers the distinct\n//! user-facing path: `transpile_to_fts5` in `src/search/query.rs`,\n//! which rewrites a raw boolean-query string into an FTS5-compatible\n//! expression. The transpiler runs on every `cass search <query>`\n//! invocation (commit c91ea038 split the sqlite FTS5 fallback into\n//! rank + hydrate phases, both of which call into this path).\n//!\n//! Scope rationale (copy of the bead's \"filed LOW\" note): fuzzing\n//! the full `SearchClient::search` path would require a stable index\n//! on disk + embedder model per invocation, violating the\n//! >1000 exec/s rule for a useful fuzz run. `transpile_to_fts5` is\n//! the tightest pure-function slice of that path that covers the\n//! quote handling, boolean operator ordering, AND/OR/NOT composition,\n//! and wildcard/phrase edge cases an adversarial user can drive.\n//!\n//!

Empty-balance: if the transpiled `Some(s)` contains\n//!      parentheses, they must be balanced — FTS5 rejects unbalanced\n//!      parens at query time, so the transpiler producing them would\n//!      surface as a downstream query error instead of a clean\n//!      \"unsupported, fall back\" signal.\n//!   3. No null byte injection: `Some(s)` output must not contain\n//!      `'\\0'` (an FTS5 query parser edge case that produced\n//!      hard-to-diagnose errors before bead al19b hardened the\n//!      error-kind vocabulary).\n\n#![no_main]\n\nuse coding_agent_search::search::query::fuzz_transpile_to_fts5;\nuse libfuzzer_sys::fuzz_target;\n\nconst MAX_QUERY_BYTES: usize = 64 * 1024;\n\nfn bounded_str(value: &str, max_bytes: usize) -> &str {\n    if value.len() <= max_bytes {\n        return value;\n    }\n    let mut end = max_bytes;\n    while !value.is_char_boundary(end) {\n        end -= 1;\n    }\n    &value[..end]\n}\n\nfuzz_target!(|raw: &str| {\n    let query = bounded_str(raw, MAX_QUERY_BYTES);\n    let Some(transpiled) = fuzz_transpile_to_fts5(query) else {\n        // `None` ⇒ the transpiler cleanly rejected an unsupported\n        // form (leading wildcards, `OR NOT`, bare leading NOT, etc.).\n        // That is the happy \"fall back to lexical\" signal — no\n        // further invariants to check.\n        return;\n    };\n\n    // Parenthesis balance.

The final rescan found one safe test-only candidate with score 5.0 and rejected lower-value public-wrapper/comment surfaces that would have risked API compatibility or reduced test readability.\n"

Rejected for this pass because several preserve public module paths/downstream imports or are tiny fixture factories.\n\n```bash\ngit ls-files '*.rs' \\\n  | rg -v '^(fuzz/|src/html_export/scripts\\.rs$|tests/e2e_large_dataset\\.rs$)' \\\n  | xargs rg -n \"(?m)^\\\\s*//\\\\s*(TODO|FIXME|HACK|Step|Phase)\\\\b\"\n```\n\nFound step/phase comments in E2E scenario tests, deploy workflows, setup wizard, and long-running index/search narratives. Rejected because they document ordered user workflows and crash/recovery phases rather than accidental slop.\n\n## Candidate Matrix\n\n| Candidate | LOC Saved | Confidence | Risk | Score | Decision |\n| --- | ---: | ---: | ---: | ---: | --- |\n| `src/encryption.rs` AES-GCM failure assertion helper | 1 | 5 | 1 | 5.0 | Accepted |\n| `src/encryption.rs` AES-GCM round-trip helper | 1 | 3 | 1 | 3.0 | Rejected: less clear tests, mixed local assertions |\n| `src/search/tantivy.rs` public pass-through wrappers | 1 | 4 | 3 | 1.3 | Rejected: public compatibility/import surface |\n| Step/phase comments in E2E/deploy tests | 1 | 2 | 2 | 1.0 | Rejected: narrative comments carry test intent |\n| `src/search/model_manager.rs` semantic setup wrappers | 1 | 3 | 3 | 1.0 | Rejected: named public entry points encode version-check policy |\n\n## Accepted Candidate\n\nExtracted a local `assert_err_contains` helper inside `src/encryption.rs` tests and replaced nine repeated `assert!(result.is_err())` plus `unwrap_err().contains(...)` pairs.\n\n## Rejected Candidates\n\n- AES-GCM round-trip helper: the repetition is visible, but the happy-path tests differ in local observations (`ciphertext.is_empty`, length checks, derived keys). Keeping them inline is clearer.\n- Tantivy/schema/model-manager wrappers: these look like pass-throughs, but they preserve stable module paths and map dependency errors at the boundary.\n- Step/phase comments: many are in workflow tests where ordered comments make the scenario auditable.\n\n## Isomorphism Card\n\n### Change\n\nCollapse repeated AES-GCM error assertion pairs into a local test helper.\n\n### Equivalence Contract\n\n- Inputs covered: the same nine `Result<_, String>` values from AES-GCM invalid length, wrong key/AAD, and tamper tests.\n- Ordering preserved: yes; each test computes the result at the same point and immediately asserts it.\n- Tie-breaking: N/A.\n- Error semantics: same requirement that the operation returns `Err` and that the error string contains the expected substring.\n- Laziness: unchanged.\n- Short-circuit eval: unchanged in observable terms; failed success path still panics before any substring assertion.\n- Floating-point: N/A.\n- RNG/hash order: unchanged; deterministic test inputs are unchanged.\n- Observable side effects: no production side effects; test failure message is more explicit.\n- Type narrowing: N/A.\n\n### Verification Plan\n\n- `cargo test aes_gcm --lib` - passed, 17 AES-GCM-related tests passed, 0 failed.\n- `rustfmt --edition 2024 --check src/encryption.rs` - passed after formatting the touched file.\n- `git diff --check -- src/encryption.rs refactor/artifacts/20260424T230127Z-repeated-simplify/pass10_final_rescan.md` - passed after intent-to-add on this artifact.\n\n## Fresh-Eyes Answer\n\nFresh-eyes review found and fixed one issue in the first helper shape: it did not reduce LOC after extraction. The helper was tightened to keep the same assertion contract while making the diff net-negative. No public API, SQLite, async, search, or connector behavior was touched.\n"

Deriving `Default` on `BundleBuilder` therefore\nconstructs the same value without routing through the trivial `new()` wrapper.\n\n### Isomorphism Card\n\n#### Change\nReplace the hand-written `Default` impl for `BundleBuilder` with\n`#[derive(Default)]`.\n\n#### Equivalence contract\n- **Inputs covered:** all `BundleBuilder::default()` and\n  `BundleBuilder::new()` callers in `src/pages/bundle.rs`,\n  `src/pages/key_management.rs`, `src/pages/wizard.rs`, and `src/lib.rs`.\n- **Ordering preserved:** yes. `Default::default()` still creates exactly one\n  `BundleConfig::default()` value before any builder setters run.\n- **Tie-breaking:** unchanged / N/A.\n- **Error semantics:** unchanged. Construction is infallible before and after.\n- **Default values:** unchanged. The only field uses the same\n  `BundleConfig::default()` implementation as `Self::new()`.\n- **Laziness:** unchanged. No lazy closure or deferred I/O was involved.\n- **Short-circuit eval:** unchanged / N/A.\n- **Floating-point:** N/A.\n- **RNG / hash order:** N/A.\n- **Observable side effects:** unchanged. No logs, metrics, DB writes, or\n  filesystem operations are in this constructor.\n- **Public API / output shapes:** unchanged. `BundleBuilder::default()`,\n  `BundleBuilder::new()`, and all builder methods remain available with the\n  same types.\n\n#### Score\n- LOC saved: 4 (small but real, in production code)\n- Confidence: 5 (single-field builder, field default unchanged)\n- Risk: 1 (single-field derive, constructor is pure and infallible)\n- Score: 20.0\n\n### Checked But Left Alone\n- `src/indexer/semantic.rs` positive `usize` env resolvers: an extracted helper\n  preserves behavior, but rustfmt makes the production diff net-positive\n  (`+3` LOC), so it was rejected and reverted.\n- `src/indexer/semantic.rs::env_backfill_min_capacity_pct()`: parses with\n  `trim()` and clamps to `1..=100`; that contract is not the same as the\n  positive `usize` fallback resolvers.\n- `src/indexer/semantic.rs::build_hnsw_index(...)`: public `Option<usize>`\n  parameters default independently to two frankensearch constants; extracting a\n  helper would save no meaningful code and would obscure the public defaults.\n- `src/update_check.rs::UpdateState::{load, load_async}`: sync and async read\n  paths share parse/default behavior, but a shared helper did not produce a\n  meaningful net-negative diff without coupling sync and async I/O.\n\n### Verification Plan\n- `rustfmt --edition 2024 --check src/pages/bundle.rs`\n- `git diff --check -- src/pages/bundle.rs refactor/artifacts/20260424T230127Z-repeated-simplify/pass6_option_default_flow.md`\n- `rch exec -- env CARGO_TARGET_DIR=${TMPDIR:-/tmp}/rch_target_cass_simplify_loop cargo test pages::bundle --lib`\n- `rch exec -- env CARGO_TARGET_DIR=${TMPDIR:-/tmp}/rch_target_cass_simplify_loop cargo check --all-targets`\n- Exact clippy if feasible; if blocked by known unrelated current-tree lint,\n  run diagnostic clippy allowing only that blocker.\n\n### Verification Results\n- `rustfmt --edition 2024 --check src/pages/bundle.rs` passed.\n- `git diff --check -- src/pages/bundle.rs refactor/artifacts/20260424T230127Z-repeated-simplify/pass6_option_default_flow.md` passed.\n- `rch exec -- env CARGO_TARGET_DIR=${TMPDIR:-/tmp}/rch_target_cass_simplify_loop cargo test pages::bundle --lib` passed: 13 passed.\n- `rch exec -- env CARGO_TARGET_DIR=${TMPDIR:-/tmp}/rch_target_cass_simplify_loop cargo check --all-targets` passed.\n- `rch exec -- env CARGO_TARGET_DIR=${TMPDIR:-/tmp}/rch_target_cass_simplify_loop cargo clippy --all-targets -- -D warnings` failed on unrelated current-tree `src/search/query.rs:5859` (`clippy::assertions-on-constants`).\n- `rch exec -- env CARGO_TARGET_DIR=${TMPDIR:-/tmp}/rch_target_cass_simplify_loop cargo clippy --all-targets -- -D warnings -A clippy::assertions-on-constants` passed.\n- `cargo fmt --check` still fails on unrelated test formatting drift in `tests/golden_robot_docs.rs`, `tests/golden_robot_json.rs`, `tests/metamorphic_agent_detection.rs`, and `tests/metamorphic_stats.rs`.\n- `ubs src/pages/bundle.rs` completed with clean fmt/clippy/check/test-build subchecks; it exits nonzero for pre-existing heuristic findings in tests and a false-positive \"hardcoded secret\" report on the `recovery_secret` setter.\n\n### LOC Ledger\n- `src/pages/bundle.rs`: 1 insertion / 6 deletions, net -5 production LOC.\n"

This is a private, single-use, constant-argument alias over the existing sidecar path constructor.\n\n### Equivalence Contract\n- Inputs covered: the single `final_path` callsite in the Windows replacement branch.\n- Ordering preserved: yes. The `let backup_path = ...` statement remains in the same position before renaming the final file.\n- Tie-breaking: unchanged. `unique_atomic_sidecar_path` still owns timestamp and nonce generation.\n- Error semantics: unchanged. The same `PathBuf` value is produced before any filesystem operation; rename and formatting branches are untouched.\n- Laziness: N/A. Both forms compute the backup path eagerly.\n- Short-circuit eval: unchanged. No boolean/control-flow change.\n- Floating-point: N/A.\n- RNG / hash order: N/A. The atomic nonce increment in `unique_atomic_sidecar_path` is still executed once at the same point.\n- Observable side-effects: identical.

It also injects live capacity rather than being a pure same-argument alias.\n- `src/ui/app.rs::unique_atomic_temp_path`: rejected because it has multiple callsites and inlining would spread the `\"tmp\"` and `\"tui_state.json\"` constants, increasing local noise for little gain.\n\n### Verification\n- `rustfmt --edition 2024 --check src/ui/app.rs` - passed.\n- `git diff --check -- src/ui/app.rs refactor/artifacts/20260425T024205Z-second-simplify/pass2_private_wrapper_collapse.md .skill-loop-progress.md` - passed.\n- `rch exec -- env CARGO_TARGET_DIR=/tmp/rch_target_cass_second_simplify cargo test --lib persisted_state_temp_paths_are_unique` - passed: 1 test passed, 0 failed, 4122 filtered out.\n- Targeted callsite census: `rg -n \"unique_atomic_sidecar_path|unique_atomic_temp_path|replace_file_from_temp|tui_state|atomic\" src/ui/app.rs tests -g '*.rs'`.\n- The changed line is in a `#[cfg(windows)]` branch. Linux test execution does not exercise that branch, so the proof rests on direct expression equivalence: the removed private helper body and the replacement call are byte-for-byte the same function call with the same arguments.\n\n### Fresh-Eyes Review\n- The initial worker diff also removed embedded source registration in `src/indexer/mod.rs` and formatted unrelated tests. That was off-mission and high risk, so those changes were manually backed out before this pass was accepted.\n- Re-read the remaining `src/ui/app.rs` diff after the cleanup.

    "content": "# Third Simplification Run Architecture Note\n\nRun id: `20260425T154730Z-third-simplify`\n\n## Documentation Context\n\n- `AGENTS.md` remains authoritative for repo-local safety rules: no file deletion, no destructive git/filesystem commands, no new `rusqlite`, no script-based code rewrites, no bare `cass`, and Cargo verification through repo-appropriate command shapes.\n- `README.md` frames cass as a Rust CLI/TUI and robot-mode API for indexing and searching local coding-agent sessions across providers, with SQLite/frankensqlite as durable truth and lexical/semantic search assets as derived state.\n\n## Current Architecture Map\n\n- `src/main.rs`: process entrypoint. It loads dotenv configuration, detects robot output mode, applies resource defaults, chooses the asupersync runtime flavor, parses CLI args, and delegates to `coding_agent_search::run_with_parsed`.\n- `src/lib.rs`: large Clap command surface and dispatch hub. It owns robot JSON contracts, friendly parse errors, command normalization, search/index/status/model/pages command routing, and many golden-pinned behaviors.\n- `src/connectors/` plus `franken_agent_detection`: provider-specific session discovery and normalization into conversation/message models.\n- `src/indexer/`: scan, salvage, canonical storage writes, lexical publish/rebuild, semantic backfill, and progress/health instrumentation. This is high-risk and currently dirty, so this loop avoids it.\n- `src/storage/`: frankensqlite-backed source of truth with legacy rusqlite debt. This is high-risk and currently dirty, so this loop avoids it.\n- `src/search/`: query parsing, lexical/hybrid/semantic search, model management, daemon client, and robot metadata. Changes here require focused tests and schema caution.\n- `src/pages/`, `src/html_export/`: export, encryption, bundle, preview, deployment, profiles, and browser-facing static assets. Good source of bounded helpers and private trait boilerplate.\n- `src/analytics/`: usage rollups, query/reporting surfaces, validation, and UI chart data. Good source of local projection or repeated validation simplifications when tests are available.\n- `src/ui/`: TUI state, rendering, data cache, charts, theme, and component helpers. High volume, but private formatting/fixture helpers can be safe when well-tested.\n- `tests/`: integration and golden contracts. Good for DRYing repeated fixture code only if test names/assertions stay unchanged.\n\n## Avoid List For This Run\n\n- `src/indexer/mod.rs`: unrelated dirty changes present at run start.\n- `src/storage/sqlite.rs`: unrelated dirty changes present at run start.\n- `.beads/*`, `benches/integration_regression.rs`, `fuzz/fuzz/`: unrelated dirty paths present at run start.\n- Full `cargo fmt --check` is known to be red on pre-existing formatting in `tests/golden_robot_docs.rs`, `tests/golden_robot_json.rs`, and `tests/metamorphic_agent_detection.rs`; do not reformat those unless the user widens scope.\n\n## Safe Simplification Strategy\n\n- Prefer private derive replacements, local helpers with three or more identical callsites, constant literal consolidation inside one module, and test fixture helpers.\n- One lever per pass, one commit per pass.\n- Each pass must include a proof card and the requested fresh-eyes review prompt before closeout.\n"

Per repo rules,\n  new SQLite work must use frankensqlite/compat APIs rather than new rusqlite.\n- Indexing: `src/indexer/*` scans connectors, writes canonical storage,\n  updates semantic data, and rebuilds/publishes lexical assets with atomic\n  swap/backup semantics.\n- Search: `src/search/*` owns lexical/vector/semantic readiness, policy,\n  query execution, model management, reranking, and daemon client integration.\n- Presentation: `src/ui/*` implements the FrankenTUI app; `src/pages/*` and\n  `src/pages_assets/*` generate browser/export pages; `src/html_export/*`\n  renders self-contained encrypted or plain HTML session exports.\n- Operations: `src/sources/*` handles remote source setup/probing/sync and path\n  mappings; `src/analytics/*` computes dashboard/bucketing/reporting data.\n\n## Data Flow\n\n```\nCLI/TUI command\n  -> command dispatch in src/lib.rs\n  -> connector discovery / source sync / session scan\n  -> normalized Conversation/Message/Snippet model\n  -> frankensqlite archive as source of truth\n  -> derived lexical/vector/semantic search assets\n  -> robot JSON, TUI views, exports, pages, analytics\n```\n\n## Refactor Safety Boundaries\n\n- Public robot JSON, error envelopes, exit-code kind strings, and golden docs\n  are stable user contracts.\n- Search indexes are derived assets; refactors must not add deletion-oriented\n  repair flows or manual index removal recipes.\n- Connector parsing preserves source provenance, timestamps, roles, and tool\n  flattening semantics.\n- HTML export and key-management changes need byte/string contract tests\n  because files are portable artifacts.\n- Any simplification crossing async, I/O, database, or search-ranking boundaries\n  is high risk and should be avoided in this loop unless thoroughly pinned.\n\n"

Core subsystems are:\n\n- `connectors/`: normalize local and remote agent session formats.\n- `storage/`: frankensqlite-backed canonical archive and migrations.\n- `indexer/`: indexing, lexical publish, semantic catch-up, and search asset repair.\n- `search/`: lexical/semantic/hybrid query support and model management.\n- `pages/` and `html_export/`: static archive generation, encryption, deploy, preview, and key management.\n- `sources/`: SSH source setup/sync/provenance.\n- `ui/`: FrankenTUI app surface.\n\n## Baseline Verification\n\n- `rch exec -- env CARGO_TARGET_DIR=/tmp/rch_target_cass_seventh_simplify cargo check --all-targets` passed.\n- `cargo fmt --check` is red only in known unrelated files:\n  - `tests/golden_robot_docs.rs`\n  - `tests/golden_robot_json.rs`\n  - `tests/metamorphic_agent_detection.rs`\n\n## Existing Dirty Work Preserved\n\nThe new run starts with unrelated dirty peer edits in:\n\n- `src/indexer/mod.rs`\n- `src/storage/sqlite.rs`\n\nThese are explicitly out of scope for this loop unless the user redirects.\n\n## Verification Shape\n\nFor each pass:\n\n1. One narrow isomorphic change.\n2. Proof card under this artifact directory.\n3. Touched-file `rustfmt --edition 2024 --check`.\n4. `git diff --check` on touched files.\n5.

    "content": "# Historical Recovery Scripts\n\nOne-off Bash/Python salvage helpers for reconstructing the canonical `cass` session database on this machine without pushing more recovery logic through Rust first.\n\nThese scripts are for:\n\n- inventorying large numbers of historical SQLite bundles\n- classifying which bundles are directly readable vs damaged\n- recovering damaged bundles with SQLite-native tooling\n- extracting only canonical session tables rather than treating FTS or Tantivy data as authoritative\n\n## Scripts\n\n`inventory_sqlite_sources.py`\n\n- Walk one or more roots and classify likely SQLite/session bundles\n- Records file size, sidecars, header state, schema readability, core table presence, and row counts when readable\n- Default output is JSONL so it can be piped into `jq`, `sqlite-utils`, or further Python processing\n\n`recover_historical_bundle.py`\n\n- Runs `sqlite3 .recover` against a damaged bundle\n- Filters the stream down to canonical session tables only\n- Imports the filtered recovery stream into a fresh SQLite database with just the core schema\n\n`merge_historical_bundle.py`\n\n- Reconciles one historical cass SQLite bundle into a canonical DB\n- Preserves existing canonical rows on same-idx conflicts\n- Only touches core tables (`sources`, `agents`, `workspaces`, `conversations`, `messages`, `snippets`)\n\n`import_codex_rollouts.py`\n\n- Scans raw Codex rollout files under `~/.codex/sessions`\n- Reconciles both missing sessions and already-known sessions that have grown more messages on disk\n- Uses `state_5.sqlite` only as metadata fallback for workspace/title/timestamps when the rollout file is incomplete\n\n`run_watch_once_batches.py`\n\n- Drives native `cass index --watch-once` over large raw session trees in resumable batches\n- Keeps all parsing/insertion logic inside `cass`; the Python only chunks paths and records progress\n- Learns a per-root batch size automatically by growing on safe headroom and shrinking on OOM or high RSS\n- Treats stderr-side `watch reindex failed` diagnostics as hard failures even if an older `cass` binary exits `0`\n- Persists per-root/per-pattern state so Claude, Codex, Gemini, and backup roots can all resume independently\n- Unsets `CASS_INDEXER_BEGIN_CONCURRENT*` by default so historical recovery stays on the safer serial writer path; pass `--allow-begin-concurrent` only if you explicitly want to benchmark that mode\n\n## Typical usage\n\nInventory the main `cass` data directory:\n\n```bash\npython3 scripts/historical_recovery/inventory_sqlite_sources.py \\\n  --root /home/ubuntu/.local/share/coding-agent-search\n```\n\nRecover one damaged bundle into a clean staging DB:\n\n```bash\npython3 scripts/historical_recovery/recover_historical_bundle.py \\\n  /home/ubuntu/.local/share/coding-agent-search/agent_search.corrupt.20260324_212907 \\\n  /tmp/agent_search.corrupt.recovered.db\n```\n\nMerge one readable historical bundle into the clean canonical clone:\n\n```bash\npython3 scripts/historical_recovery/merge_historical_bundle.py \\\n  /home/ubuntu/.local/share/coding-agent-search/agent_search.db.backup.253251.1774560539243940632.0 \\\n  --canonical-db /home/ubuntu/.local/share/coding-agent-search/repair-lab/agent_search.canonical_dumpclone_1774564525.db\n```\n\nReconcile raw Codex rollout sessions into the clean canonical clone:\n\n```bash\npython3 scripts/historical_recovery/import_codex_rollouts.py \\\n  --canonical-db /home/ubuntu/.local/share/coding-agent-search/repair-lab/agent_search.canonical_dumpclone_1774564525.db \\\n  --sessions-root /home/ubuntu/.codex/sessions \\\n  --state-db /home/ubuntu/.codex/state_5.sqlite\n```\n\nReconcile a large Gemini raw-session tree through native `cass` in resumable batches:\n\n```bash\npython3 scripts/historical_recovery/run_watch_once_batches.py \\\n  --data-dir /home/ubuntu/.local/share/coding-agent-search/repair-lab/reconcile_from_native_full_20260328 \\\n  --root /home/ubuntu/.gemini/tmp \\\n  --pattern '**/session-*.json' \\\n  --batch-size 32\n```\n\nSave the filtered SQL stream too:\n\n```bash\npython3 scripts/historical_recovery/recover_historical_bundle.py \\\n  /path/to/bundle.db \\\n  /tmp/recovered.db \\\n  --filtered-sql /tmp/recovered.filtered.sql\n```\n\n## Notes\n\n- These scripts do not delete or overwrite source bundles.\n- Recovered DBs should be treated as staging inputs for later dedup/merge work.\n- The source of truth should remain the final canonical `agent_search.db`, rebuilt only after staged salvage is complete.\n- For large recovery passes, leave BEGIN CONCURRENT disabled unless you have already proven that specific DB + workload is stable with `--allow-begin-concurrent`.\n"

Lexical generation manifests and publish-state vocabulary (bead ibuuh.30).\n//!\n//! The authoritative lexical rebuild pipeline from bead ibuuh.29 emits an\n//! equivalence ledger proving what it ingested, but publish semantics are still\n//! \"one mutable `<data_dir>/index` directory\". That leaves ordinary search\n//! vulnerable to half-built artifacts during rebuild, crash, or parallel\n//! experimentation.\n//!\n//! This module lands the *vocabulary* for the generation-based publish path:\n//! a versioned manifest that describes a single lexical generation's\n//! identity, build state, publish state, source fingerprint, and failure\n//! history, plus atomic load / store helpers. It is intentionally isolated\n//! from the rebuild pipeline in this slice; downstream slices will wire the\n//! authoritative rebuild to produce these manifests in scratch directories,\n//! promote them to `published`, and teach startup recovery to choose the\n//! right generation.\n//!\n//! Invariants the type enforces:\n//! - The schema version is explicit so future migrations can refuse or\n//!   upgrade older manifests cleanly.\n//! - Build state and publish state are independent enums so the lifecycle\n//!   (\"built but not yet validated\", \"validated but not yet published\",\n//!   \"published but superseded\") is representable without overloading a\n//!   single state field.\n//! - Failure history is an append-only log so crash-resume tooling can see\n//!   why previous attempts were abandoned, including which attempt id, at\n//!   which phase, and with what message.\n//! - Counts and fingerprints live alongside state so a single manifest\n//!   answers both \"is this generation safe to serve?\" and \"does it\n//!   correspond to the expected DB?\".\n\nuse std::collections::BTreeMap;\nuse std::fs;\nuse std::io::{BufWriter, Write};\nuse std::path::{Path, PathBuf};\nuse std::time::{SystemTime, UNIX_EPOCH};\n\nuse anyhow::{Context, Result};\nuse serde::{Deserialize, Serialize};\n\n/// Current manifest format version.

Parallel-WAL shadow observer (Card 1, `§15.4 Silo/Aether` in the alien\n//! graveyard). **This module does NOT change commit semantics.** Per the\n//! design in `tests/artifacts/perf/2026-04-21-profile-run/ALIEN-ARTIFACT-CARD1-SPEC.md`\n//! §5.7, the shadow-run is the mandatory first rollout stage: we run the\n//! existing `persist_conversations_batched_begin_concurrent` path\n//! unchanged, but instrument it so we can see what an epoch-ordered\n//! group-commit path *would* do on the same workload.\n//!\n//! The goal at this stage is pure telemetry:\n//!\n//! * record when each writer chunk starts, ends, and how long it takes;\n//! * note the \"would-have-coalesced\" boundaries where a parallel-WAL\n//!   coordinator would have issued one combined epoch fsync instead of N;\n//! * publish the numbers via `ParallelWalShadowTelemetry` so an\n//!   operator can inspect them through `cass health --json`.\n//!\n//! Once we have 100+ consecutive shadow runs with stable numbers and no\n//! surprises, the committing path can be written *on top of* this\n//! observer — exactly the Shadow → Canary → Ramp → Default rollout the\n//! spec demands. Until then, enabling this module costs only the shadow\n//! counters' ~100 ns per chunk.\n//!\n//! Activation:\n//! ```text\n//! (unset)                             # DEFAULT: shadow observer ON\n//!

    "content": "//! Machine-responsiveness governor for the indexing pipeline.\n//!\n//! The indexer can easily saturate every core of a big host. That is normally\n//! fine on a dedicated build box, but on a shared workstation it makes\n//! interactive shells, editors, and a foreground `cass search` feel dead\n//! while a rebuild runs. This module provides a lightweight, hysteresis-aware\n//! governor that publishes a *capacity factor* (an integer percentage in\n//! `[min_capacity_pct, 100]`). Callers consult [`effective_worker_count`]\n//! before committing to a worker fan-out, and get back a bounded count that\n//! respects the current system load.\n//!\n//! Design goals (aligned with bead `coding_agent_session_search-d2qix`):\n//!\n//! * **Conservative by default.** Defaults never grow past caller-requested\n//!   fan-out; they only shrink when the box is already under pressure.\n//! * **Explainable.** Thresholds live in named env vars and the full decision\n//!   history is queryable via [`telemetry_snapshot`].\n//! * **Non-oscillating.** Shrink is immediate so responsiveness recovers\n//!   fast, but growth back to full capacity requires multiple consecutive\n//!   healthy ticks (hysteresis) so flapping loads do not flap the worker count.\n//! * **Opt-out.** `CASS_RESPONSIVENESS_DISABLE=1` pins capacity to 100% for\n//!   before/after comparison runs and sandboxed environments.\n//!\n//! Signals read on Linux:\n//!\n//! * `/proc/loadavg` first field (1-minute load average), compared against\n//!   the number of logical CPUs.\n//! * `/proc/pressure/cpu` `some avg10` (percent of wall-time some task was\n//!   delayed on CPU in the last 10s). This is the best single \"how\n//!   unresponsive does the machine feel\" signal available from the kernel.\n//!\n//!

    "content": "//! Typed `CliError.kind` enum (`coding_agent_session_search-dxnmb`).\n//!\n//! `CliError.kind` is currently a `&'static str` field with 86 unique\n//! values scattered as string literals across `src/lib.rs`. There is\n//! no compile-time exhaustiveness check, no naming-convention guard,\n//! and no rename-safety. A hurried maintainer can:\n//!\n//! - typo a kind (\"db_error\" vs \"db-error\") without compiler error,\n//! - introduce a new kind that shadows an existing one,\n//! - use inconsistent casing (the existing literal set already has\n//!   4 snake_case stragglers — `failed_seed_bundle_file`,\n//!   `lexical_generation`, `lexical_shard`, `retained_publish_backup`\n//!   — alongside the canonical kebab-case majority).\n//!\n//! That inconsistency caused 3 real duplicates pinned by bead `al19b`.\n//!\n//! This module ships the **vocabulary slice** of the dxnmb fix:\n//! a single source-of-truth enum that:\n//!\n//! 1. enumerates every kind currently emitted by `src/lib.rs`\n//!    (audited at landing time via `grep -oE 'kind: \"[a-z_-]+\"'`),\n//! 2. exposes a `kind_str()` accessor that returns the canonical\n//!    kebab-case (or, for the four snake_case stragglers, the exact\n//!    legacy literal — preserving wire compatibility with golden\n//!    tests + downstream agents until those four are migrated in a\n//!    separate slice),\n//! 3. exposes a `from_kind_str()` lookup so JSON-mode consumers\n//!    (and golden tests) can round-trip the kind cleanly.\n//!\n//! The actual migration of the 223 call sites in `src/lib.rs` (each\n//! `CliError { kind: \"...\", ... }` literal → `CliError { kind:\n//! ErrorKind::Foo.as_str(), ... }`) is the *follow-up* slice; it\n//! requires write access to `src/lib.rs` which is currently held by\n//! another agent's exclusive file reservation. Landing the\n//! vocabulary first lets that follow-up slice land as a pure\n//! mechanical replacement gated by the golden test below.\n//!\n//! # Variant naming\n//!\n//! Variants use Rust's standard CamelCase. The mapping to the\n//! wire-format string is held by `kind_str()` rather than by\n//! `#[serde(rename = \"...\")]` because the four snake_case stragglers\n//! cannot be auto-generated from CamelCase by serde's\n//! `rename_all = \"kebab-case\"` (e.g. `LexicalGeneration` would\n//! serialize as `lexical-generation`, breaking the existing\n//! `kind: \"lexical_generation\"` wire contract). The audit golden\n//! test pins both the kebab-case canonical kinds AND the snake_case\n//! exemptions so a future cleanup slice that migrates the four\n//! stragglers to kebab-case has an explicit place to flip the\n//! contract.\n\nuse serde::{Deserialize, Serialize};\n\n/// Typed counterpart to `CliError.kind`.

This\n//! module is that compare-mode hook.\n//!\n//! Two packets compared by [`PacketEquivalenceAuditor::audit_pair`] are\n//! considered equivalent when their projections agree byte-for-byte and\n//! their hashes either match or are explicitly excused by a documented\n//! tolerance (e.g. secret redaction is enabled, so the canonical content\n//! string differs from the raw content string and `semantic_hash` is\n//! expected to drift while `analytics`/`lexical`/`semantic` projections\n//! are still required to match).\n//!\n//! The audit is intentionally pure: it consumes already-built packets and\n//! returns a structured outcome. Callers wire the env-gated kill-switch\n//! (`CASS_INDEXER_PACKET_EQUIVALENCE_AUDIT`) at their site so this module\n//! stays cheap to import and trivially testable.\n\nuse serde::{Deserialize, Serialize};\n\nuse crate::model::conversation_packet::{\n    ConversationPacket, ConversationPacketAnalyticsProjection, ConversationPacketLexicalProjection,\n    ConversationPacketSemanticProjection,\n};\n\n/// Env knob (1/true/yes ⇒ enabled) that opts the live persist path into\n/// emitting compare-mode audit records.

=============================================================================\n\nconst README_TEMPLATE: &str = r#\"# Encrypted Coding Session Archive\n\nThis repository contains an encrypted archive of coding session histories,\ncreated with [CASS](https://github.com/Dicklesworthstone/coding_agent_session_search).\n\n## Quick Access\n\nOpen the web viewer: [{url}]({url})\n\n## What This Contains\n\nThis archive includes {conversation_count} conversations from the following sources:\n{agent_list}\n\nDate range: {start_date} to {end_date}\n\n## Accessing the Archive\n\n### Option 1: Password\nEnter the password at the web viewer to decrypt and browse the archive.\n\n### Option 2: QR Code (if configured)\nScan the QR code with your phone camera to auto-fill the decryption key.\n\n## Security\n\nThis archive is protected with:\n- **Encryption**: AES-256-GCM (authenticated encryption)\n- **Key Derivation**: Argon2id with {argon_params}\n- **Key Slots**: {slot_count} independent decryption key(s)\n\nThe encrypted archive can be safely hosted publicly. Only someone with a valid\npassword or QR code can decrypt the contents.\n\nFor detailed security information, see [SECURITY.md](SECURITY.md).\n\n## Recovery\n\nIf you forget your password:\n- Use the recovery key (if you saved one during setup)\n- The archive owner may have additional key slots\n\nWithout a valid key, the archive cannot be decrypted.\n\n---\nGenerated by CASS v{version} on {date}\n\"#;\n\nconst SECURITY_TEMPLATE: &str = r#\"# Security Model\n\n## Overview\n\nThis document describes the security properties of this encrypted archive.\n\n## Threat Model\n\n### What This Protects Against\n\n- **Casual access**: Random visitors cannot read content\n- **Server compromise**: GitHub/hosting provider cannot read your data\n- **Network interception**: Content is encrypted before transmission\n- **Brute force (with strong password)**: Argon2id makes guessing expensive\n\n### What This Does NOT Protect Against\n\n- **Weak passwords**: Short or common passwords can be cracked\n- **Password sharing**: Anyone with the password can decrypt\n- **Endpoint compromise**: Malware on your device can capture passwords\n- **Targeted attacks**: Determined attackers with resources may succeed\n- **Quantum computers**: AES-256 may be weakened by future advances\n\n## Encryption Details\n\n### Envelope Encryption\n\nThe archive uses envelope encryption:\n1. A random 256-bit Data Encryption Key (DEK) encrypts the data\n2. The DEK is encrypted with a Key Encryption Key (KEK) derived from your password\n3. Multiple key slots allow different passwords to decrypt the same data\n\n### Algorithms\n\n| Component | Algorithm | Parameters |\n|-----------|-----------|------------|\n| Data Encryption | AES-256-GCM | 96-bit nonce, 128-bit tag |\n| Key Derivation | Argon2id | m={memory}KB, t={iterations}, p={parallelism} |\n| DEK Encryption | AES-256-GCM | Same as data |\n| Nonce Generation | Counter-based | Prevents reuse |\n\n### Key Slots\n\nThis archive has {slot_count} key slot(s):\n{slot_descriptions}\n\nEach slot contains the same DEK encrypted with a different KEK.\n\n## Verification\n\n### Checking Archive Integrity\n\nThe AES-GCM authentication tag ensures:\n- Data has not been modified\n- Decryption used the correct key\n\nIf decryption fails, the archive was either:\n- Corrupted in transit\n- Modified by an attacker\n- Decrypted with wrong key\n\n### Verifying Implementation\n\nThis archive was created with CASS, an open-source tool. You can:\n1. Review the source code at {repo_url}\n2. Verify the implementation uses standard libraries\n3. Audit the cryptographic construction\n\n## Recommendations\n\n1. **Use a strong password**: 16+ characters, or 5+ random words\n2. **Store recovery key safely**: It is the only backup\n3. **Rotate passwords periodically**: Generate new archive with new key\n4. **Limit distribution**: Share URL only with intended recipients\n\n## Contact\n\nFor security issues with CASS, see {repo_url}/security\n\n---\nGenerated by CASS v{version}\n\"#;\n\nconst HELP_HTML_TEMPLATE: &str = r#\"<!DOCTYPE html>\n<html lang=\"en\">\n<head>\n    <meta charset=\"UTF-8\">\n    <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\">\n    <title>Help - CASS Archive</title>\n    <style>\n        :root {\n            --bg-primary: #1a1a2e;\n            --bg-secondary: #16213e;\n            --text-primary: #eee;\n            --text-secondary: #aaa;\n            --accent: #e94560;\n            --border: #333;\n        }\n        * { box-sizing: border-box; }\n        body {\n            font-family: system-ui, -apple-system, sans-serif;\n            max-width: 800px;\n            margin: 0 auto;\n            padding: 20px;\n            background: var(--bg-primary);\n            color: var(--text-primary);\n            line-height: 1.6;\n        }\n        h1, h2, h3 {\n            color: var(--text-primary);\n            border-bottom: 1px solid var(--border);\n            padding-bottom: 0.5em;\n        }\n        h1 { font-size: 1.8rem; }\n        h2 { font-size: 1.4rem; margin-top: 2em; }\n        h3 { font-size: 1.1rem; margin-top: 1.5em; border: none; }\n        code {\n            background: var(--bg-secondary);\n            padding: 2px 6px;\n            border-radius: 3px;\n            font-family: 'SF Mono', Monaco, monospace;\n            font-size: 0.9em;\n        }\n        ul { padding-left: 1.5em; }\n        li { margin: 0.5em 0; }\n        .warning {\n            background: #3d2f00;\n            padding: 15px;\n            border-left: 4px solid #ffc107;\n            border-radius: 4px;\n            margin: 1em 0;\n        }\n        .info {\n            background: #0d3a5c;\n            padding: 15px;\n            border-left: 4px solid #17a2b8;\n            border-radius: 4px;\n            margin: 1em 0;\n        }\n        a { color: var(--accent); }\n        .back-link {\n            display: inline-block;\n            margin-top: 2em;\n            padding: 10px 20px;\n            background: var(--accent);\n            color: white;\n            text-decoration: none;\n            border-radius: 4px;\n        }\n        .back-link:hover { opacity: 0.9; }\n    </style>\n</head>\n<body>\n    <h1>Help</h1>\n\n    <h2>Accessing the Archive</h2>\n    <p>Enter your password in the unlock screen.

    "content": "//! Semantic policy contract for cass hybrid search.\n//!\n//! This module is the **single source of truth** for all semantic search policy\n//! decisions.  Downstream beads (asset manifests, backfill scheduler, model\n//! acquisition, configuration surfaces, capability reporting) implement against\n//! the types and constants defined here rather than guessing or hardcoding their\n//! own values.\n//!\n//! # Product contract\n//!\n//! Ordinary search **always works lexically**.  Semantic quality improves\n//! opportunistically: when model files are present, vectors are built in the\n//! background and hybrid results are blended in.  A missing or broken semantic\n//! tier never blocks or degrades lexical search.\n//!\n//! # Precedence (lowest to highest)\n//!\n//! 1. **Compiled defaults** — [`SemanticPolicy::compiled_defaults`]\n//! 2. **Persisted config** — `~/.config/cass/semantic.toml` (planned)\n//! 3. **Environment variables** — `CASS_SEMANTIC_*`\n//! 4. **CLI flags** — `--semantic-mode`, `--semantic-budget-mb`, etc.\n//!\n//! Higher layers override lower layers field-by-field; unset fields inherit.\n//!\n//! # Behaviour modes\n//!\n//! | Mode | Lexical | Fast-tier semantic | Quality-tier semantic |\n//! |------|---------|--------------------|----------------------|\n//! | `HybridPreferred` (default) | always | if available | if model present |\n//! | `LexicalOnly` | always | never | never |\n//! | `StrictSemantic` | always (floor) | required | required |\n//!\n//! `StrictSemantic` is for callers that want hard guarantees about semantic\n//! quality (e.g., bake-off).  It is never the default.\n//!\n//! # Storage budget\n//!\n//! Semantic artifacts are **derivative** — they can always be rebuilt from the\n//! canonical SQLite database.  They must never crowd out the DB or the required\n//! lexical index.\n//!\n//! Eviction order (first to go → last to go):\n//! 1. HNSW accelerator indices (`.chsw`)\n//! 2. Quality-tier vector index (`.fsvi`)\n//! 3. Fast-tier vector index\n//! 4. Downloaded model files\n//!\n//!

Downstream slices will plug these types into the JSON payload\n// builders in src/lib.rs and the TUI status surface.\n#![allow(dead_code)]\n\n//! Truthful readiness-state vocabulary for lexical vs. semantic search\n//! (bead ibuuh.9).\n//!\n//! Today cass reports a single \"healthy / unhealthy\" bit that conflates\n//! \"lexical index missing\" (actually broken — search returns nothing),\n//! \"lexical index stale but searchable\" (slightly old but fully correct),\n//! \"lexical index rebuilding in background\" (search works, new content\n//! will land shortly), and \"semantic tier still backfilling\" (lexical\n//! results are complete, hybrid refinement catches up later). Agents and\n//! humans keep triggering unnecessary repair rituals because the single\n//! health bit cannot distinguish these cases.\n//!\n//! This module lands the vocabulary that future status/capabilities/\n//! search-metadata payloads will project into their JSON. The fields are\n//! intentionally orthogonal — lexical readiness and semantic readiness\n//! are independent dimensions, and the user-facing `recommended_action`\n//! is derived from their combination rather than dropping them behind a\n//! single scalar.\n//!\n//! Invariants the types enforce:\n//! - `LexicalReadinessState` covers the five states any agent must be\n//!   able to distinguish: `Missing`, `Repairing`, `StaleButSearchable`,\n//!   `Ready`, `CorruptQuarantined`. Ordinary search is correct in\n//!   `StaleButSearchable` and `Ready` (and degrading-but-serving in\n//!   `Repairing`); it is only unavailable in `Missing` and\n//!   `CorruptQuarantined`.\n//! - `SemanticReadinessState` covers `Absent`, `Backfilling`,\n//!   `FastTierReady`, `HybridReady`, `PolicyDisabled`. Absence and\n//!   policy-disabled both mean \"no semantic refinement\" but have\n//!   different operator implications.\n//! - `SearchRefinementLevel` describes what a PARTICULAR completed\n//!   search actually returned (`LexicalOnly`, `FastTierRefined`,\n//!   `FullyHybridRefined`). This is independent of the tier\n//!   *readiness* above — a search may be `LexicalOnly` either because\n//!   the semantic tier was absent or because the planner chose not to\n//!   refine.\n//! - `ReadinessSnapshot` groups all three plus a\n//!   `RecommendedAction` so every downstream consumer (CLI, TUI,\n//!   robot) derives its summary from the same canonical source.\n\nuse serde::{Deserialize, Serialize};\n\n#[derive(Debug, Clone, Copy, PartialEq, Eq, Hash, Serialize, Deserialize)]\n#[serde(rename_all = \"snake_case\")]\npub(crate) enum LexicalReadinessState {\n    /// No usable lexical index exists on disk.

This module provides rich interactive components using dialoguer, including:\n//! - Multi-select host picker with multi-line item display\n//! - Confirmation prompts for destructive operations\n//!\n//! # Design Decision: dialoguer vs inquire\n//!\n//! We chose dialoguer because:\n//! 1. It integrates well with indicatif (already used for progress bars)\n//! 2. It's actively maintained and widely used\n//! 3. It supports ANSI styling in items via the console crate\n//!\n//! # Multi-line Item Display\n//!\n//! Standard dialoguer MultiSelect shows single-line items. We achieve multi-line\n//! display by embedding ANSI escape sequences and newlines directly in item strings:\n//!\n//! ```text\n//!

This module underwent a comprehensive UX overhaul migrating from ratatui to ftui\n//! (a custom Elm-architecture framework). Key subsystems introduced:\n//!\n//! ## Command Palette\n//!\n//! Keyboard-first action dispatch via Ctrl+P / Alt+P. The palette provides fuzzy\n//! search over ~28 action variants grouped into 7 categories (Chrome, Filter, View,\n//! Analytics, Export, Recording, Sources). Filtering uses Bayesian-scored matching\n//! with six modes (All/Exact/Prefix/WordStart/Substring/Fuzzy) cycled via F9.\n//! See [`PaletteState`] in `components/palette.rs` for state, and\n//! [`PaletteLatencyStats`] for query performance instrumentation.\n//!\n//! **Design tradeoff**: Bayesian scoring adds ~50μs per keystroke but produces\n//! significantly better ranking than simple substring matching. The latency budget\n//! indicator (OK <200μs, WARN <1000μs, SLOW ≥1000μs) keeps this measurable.\n//! Alt+B toggles a micro-bench overlay showing queries/second throughput.\n//!\n//! ## Responsive Layout\n//!\n//! Terminal width drives [`LayoutBreakpoint`] (Narrow <80, MediumNarrow 80-119,\n//! Medium 120-159, Wide ≥160). Each breakpoint maps to concrete topology contracts:\n//! - [`SearchTopology`]: pane widths, split handle, dual-pane toggle\n//! - [`AnalyticsTopology`]: tab bar, filter summary, header rows, footer hints\n//! - [`VisibilityPolicy`]: theme label, hint slots/budget, saved-view path length\n//!\n//! Ultra-narrow terminals (<30 cols or <6 rows) get a \"terminal too small\" fallback\n//! rather than a broken layout.\n//!\n//! ## Analytics Explorer\n//!\n//! Seven views under [`AnalyticsView`]: Dashboard, Explorer, Heatmap, Breakdowns,\n//! Tools, Plans, Coverage. The Explorer view supports interactive cycling of:\n//! - [`ExplorerMetric`] (m/M): ApiTokens, ContentTokens, Messages, ToolCalls, etc.\n//! - [`ExplorerOverlay`] (o): None, ByAgent, ByWorkspace, BySource\n//! - [`ExplorerZoom`] (z/Z): All, 24h, 7d, 30d, 90d\n//! - GroupBy (g/G): Hour, Day, Week, Month\n//!\n//! Chart data is pre-computed via `load_chart_data()` in `analytics_charts.rs`.\n//!\n//! ## Inspector & Diagnostics\n//!\n//! Ctrl+Shift+I opens the inspector overlay with 7 tabs ([`InspectorTab`]):\n//! Timing, Layout, HitRegions, Resize, Diff, Budget, Timeline. Each tab renders\n//! from [`EvidenceSnapshots`], which are updated per-tick from ftui's evidence\n//! telemetry rather than re-parsing log files at render time.\n//!\n//! [`FrameTimingStats`] maintains a rolling ring buffer of frame durations for\n//! FPS calculation and jitter detection.\n//!\n//! ## Theme Cycling\n//!\n//! F2 cycles forward through 18 preset themes; Shift+F2 cycles backward.\n//! Theme selection persists to `theme.json` in the data directory.\n//!\n//! ## Key Bindings\n//!\n//! Modal interceptors form a priority stack: inspector > palette >\n//! normal key handling. When a modal is open, it captures all input except its own\n//! dismiss/close messages, which must be explicitly passed through (not swallowed\n//! by `_ => Cmd::none()` wildcards).\n//!\n//! ## Test Coverage\n//!\n//! - 532 unit tests in this module (palette, latency, responsive, inspector, etc.)\n//! - 59 unit tests in `components/palette.rs`\n//! - 74 cross-workstream integration tests in `tests/cross_workstream_integration.rs`\n//! - Key regression suites: palette lifecycle, dispatch coverage for all 28 action\n//!   variants, responsive SIZE_MATRIX (16 entries), perf envelope checks\n\nuse std::cell::{Cell, RefCell};\nuse std::collections::{BTreeSet, HashMap, HashSet, VecDeque};\nuse std::path::{Path, PathBuf};\nuse std::process::Command as StdCommand;\nuse

Summary\nRefactored the auth module to use **JWT tokens** with `refresh_token` rotation.\n\n### Changes\n- Replaced session cookies with signed JWTs\n- Added `HMAC-SHA256` signature verification\n- Implemented sliding window rate limiting\n\n```rust\nfn verify_token(token: &str) -> Result<Claims> {\n    let key = load_signing_key()?;\n    decode::<Claims>(token, &key,

|\n|----------|----------|----------|\n| `/api/users` | Cookie | JWT |\n| `/api/admin` | Cookie+CSRF | JWT+Role |\n| `/webhook` | API Key | JWT+Scope |\n\n1.

This gap matters especially for agents\n// running air-gapped installs: they consume the JSON error envelope\n// to decide what to do next.\n//\n// Contract pinned here, for the two cases that don't need the real\n// ~90MB MiniLM model (which this test fixture deliberately avoids):\n//   1. --from-file <nonexistent-path>\n//      - exit 21, err.kind == \"model\", err.code == 21,\n//        err.retryable == false, hint names \"directory\" + expected\n//        model file examples.\n//   2. --from-file <empty-dir>\n//      - exit 21, err.kind == \"model\", err.code == 21,\n//        err.retryable == false, hint enumerates the required file set\n//        (model.onnx, tokenizer.json, config.json, ...).\n// ========================================================================\n\n#[test]\nfn models_install_from_file_nonexistent_path_emits_model_error_envelope() {\n    use assert_cmd::cargo::cargo_bin;\n    use serde_json::Value;\n\n    let tmp = tempfile::tempdir().expect(\"tempdir\");\n    let data_dir = tmp.path().join(\"cass-data\");\n    std::fs::create_dir_all(&data_dir).expect(\"create data dir\");\n    let nonexistent = tmp.path().join(\"definitely-not-there\");\n    assert!(\n        !nonexistent.exists(),\n        \"precondition: target path must not exist\"\n    );\n\n    let output = std::process::Command::new(cargo_bin(\"cass\"))\n        .args([\"models\", \"install\", \"--from-file\"])\n        .arg(&nonexistent)\n        .args([\"--yes\", \"--robot-format\", \"json\", \"--data-dir\"])\n        .arg(&data_dir)\n        .env(\"CODING_AGENT_SEARCH_NO_UPDATE_PROMPT\", \"1\")\n        .env(\"CASS_IGNORE_SOURCES_CONFIG\", \"1\")\n        .env(\"HOME\", tmp.path())\n        .env(\"XDG_DATA_HOME\", tmp.path().join(\".local/share\"))\n        .env(\"XDG_CONFIG_HOME\", tmp.path().join(\".config\"))\n        .output()\n        .expect(\"run cass models install\");\n\n    let exit = output.status.code().expect(\"exit code present\");\n    let stdout = String::from_utf8_lossy(&output.stdout);\n    let stderr = String::from_utf8_lossy(&output.stderr);\n    assert_eq!(\n        exit, 21,\n        \"--from-file pointing at a nonexistent path must exit 21 (model kind);

Fixtures\n\n1. **Use real data** — Capture from actual agent sessions when possible\n2. **Redact sensitive info** — Anonymize usernames, paths, credentials\n3. **Add to MANIFEST** — Update `connectors/MANIFEST.json` with SHA256\n4. **Document the scenario** — Update this README and add fixture-specific README if complex\n5. **Link to tests** — Note which test files exercise the fixture\n\n## Fixture Loading Helpers\n\nCommon fixture loading utilities are in `tests/fixture_helpers.rs`:\n\n```rust\nuse fixture_helpers::{\n    load_fixture,                    // Load fixture file as string\n    copy_fixture,                    // Copy fixture to temp location\n    embedder_fixture_dir,            // Path to embedding model fixtures\n    reranker_fixture_dir,            // Path to reranker model fixtures\n    verify_model_fixture_checksums,  // Verify ONNX model integrity\n    setup_connector_test,            // Create temp test environment\n    create_project_dir,              // Create project within test env\n    write_session_file,              // Write session file to test env\n};\n```\n\n## No-Mock Policy\n\nPer `TESTING.md`, this project avoids mocks in favor of real fixtures:\n\n- **Connector tests** use real session files from each agent\n- **Database tests** use real SQLite with known data\n- **HTTP tests** use embedded servers with fixture responses\n- **Model tests** use real (quantized) ONNX models\n\nThis approach provides higher confidence that tests reflect production behavior.\n"

Memory/FD Leak (Critical)\\n```rust\\nself.active_connections.push(socket.into_std().unwrap());\\n```\\nConnections are added to `Vec` but **never removed** when they close. This causes:\\n- Growing memory usage\\n- Potential FD leak if `TcpStream` isn't dropped\\n\\n### 2. Unwrap on Accept (Causes Panic)\\n```rust\\nlet (socket, addr) = self.listener.accept().await.unwrap();  // 💥\\n```\\nWhen FDs are exhausted, `accept()` returns `Err`, and `unwrap()` panics.\\n\\n### 3. Resource Tracking is Broken\\nThe `active_connections` Vec serves no purpose since:\\n- It stores `std::net::TcpStream` (blocking)\\n- But the actual connection uses `tokio::net::TcpStream` (async)\\n- The stored stream is never used\\n\\n## Fix #1: Proper Error Handling\\n\\n```rust\\nimpl ConnectionHandler {\\n    pub async fn accept(&mut self) -> std::io::Result<()> {\\n        loop {\\n            match self.listener.accept().await {\\n                Ok((socket, addr)) => {\\n                    tracing::info!(\\\"New connection from: {}\\\", addr);\\n                    tokio::spawn(handle_connection(socket));\\n                }\\n                Err(e) if e.kind() == std::io::ErrorKind::WouldBlock => {\\n                    // Transient, retry\\n                    tokio::time::sleep(Duration::from_millis(10)).await;\\n                }\\n                Err(e) => {\\n                    tracing::error!(\\\"Accept error: {:?}\\\", e);\\n                    // Back off on FD exhaustion\\n                    if e.raw_os_error() == Some(24) {  // EMFILE\\n                        tracing::warn!(\\\"FD exhaustion - backing off\\\");\\n                        tokio::time::sleep(Duration::from_secs(1)).await;\\n                    }\\n                }\\n            }\\n        }\\n    }\\n}\\n```\\n\\n## Fix #2: Connection Tracking with Cleanup\\n\\nIf you need to track active connections (for graceful shutdown, etc.):\\n\\n```rust\\nuse std::sync::atomic::{AtomicUsize, Ordering};\\nuse std::sync::Arc;\\n\\npub struct ConnectionHandler {\\n    listener: TcpListener,\\n    active_count: Arc<AtomicUsize>,\\n    max_connections: usize,\\n}\\n\\nimpl ConnectionHandler {\\n    pub async fn accept(&self) -> std::io::Result<()> {\\n        loop {\\n            // Back-pressure: reject if at capacity\\n            let current = self.active_count.load(Ordering::Relaxed);\\n            if current >= self.max_connections {\\n                tracing::warn!(\\\"At connection limit ({})\\\", self.max_connections);\\n                tokio::time::sleep(Duration::from_millis(100)).await;\\n                continue;\\n            }\\n\\n            match self.listener.accept().await {\\n                Ok((socket, addr)) => {\\n                    let counter = self.active_count.clone();\\n                    counter.fetch_add(1, Ordering::Relaxed);\\n                    \\n                    tokio::spawn(async move {\\n                        handle_connection(socket).await;\\n                        counter.fetch_sub(1, Ordering::Relaxed);  // Decrement on close!\\n                    });\\n                }\\n                Err(e) => {\\n                    tracing::error!(\\\"Accept failed: {:?}\\\", e);\\n                    tokio::time::sleep(Duration::from_millis(50)).await;\\n                }\\n            }\\n        }\\n    }\\n}\\n```\\n\\nShould I also show you how to increase the FD limit at the system level?\"},\"uuid\":\"msg-004\",\"timestamp\":\"2026-01-12T15:02:30.000Z\"}\n{\"sessionId\":\"gemini-debug-001\",\"workspace\":\"/home/dev/backend\",\"agent\":\"gemini\",\"type\":\"user\",\"message\":{\"role\":\"user\",\"content\":\"Yes please, I want to increase the limit as well for safety.\"},\"uuid\":\"msg-005\",\"timestamp\":\"2026-01-12T15:03:00.000Z\"}\n{\"sessionId\":\"gemini-debug-001\",\"workspace\":\"/home/dev/backend\",\"agent\":\"gemini\",\"type\":\"assistant\",\"message\":{\"role\":\"assistant\",\"content\":\"Here's how to properly configure FD limits:\\n\\n## 1.

Captures the full\nnot-installed state: `state=\"not_acquired\"`, `state_detail` missing-file\nlisting, `next_step` user-facing hint, `files[]` per-manifest-file sizes,\nand the `cache_lifecycle` sub-structure (state machine + per-file\n`last_check_at_ms`). Paths to `model_dir` and per-file locations are\nscrubbed to `[TEST_HOME]/...`.\n\n**Command:** `cass models status --json` with `XDG_DATA_HOME`, `HOME`,\nand `CASS_IGNORE_SOURCES_CONFIG=1` all pinned to an isolated TempDir so\nthe model cache is guaranteed empty. Shape includes every field\n`run_models_status` emits in the JSON branch of the structured output.\n\n### `html_export/basic_export.html.golden`\n\nFrozen full document from `cass export-html --json --no-cdns`\nagainst a three-message Claude-style JSONL fixture generated by\n`tests/pages_export_golden.rs::write_fixture_session`. Captures the doctype,\nmetadata, style block, script block, and rendered user/assistant message HTML.\n\n**Command:** `cass export-html <fixture.jsonl> --output-dir <temp> --filename basic_export.html --json --no-cdns`\nwith `HOME`, `XDG_CONFIG_HOME`, and `XDG_DATA_HOME` pinned to an isolated\nTempDir.\n\n### `html_export/encrypted_export.html.golden`\n\nFrozen full document from the same fixture and flags plus `--encrypt` with the\nfixture phrase generated by `tests/pages_export_golden.rs`. Test builds set\n`CASS_HTML_EXPORT_GOLDEN_BYTES_LABEL=z2hck-html-export-golden-v1` so\nsalt/IV/ciphertext are reproducible before the scrubber replaces those bytes\nwith `[SCRUBBED-*]` placeholders.\n\n**Command:** `printf '%s\\n' <fixture-phrase> | cass export-html <fixture.jsonl> --output-dir <temp> --filename encrypted_export.html --json --no-cdns --encrypt --password-stdin`.\n\n## Follow-ups\n\nGoldens still to add under bead u9osp scope (each needs its own\nenvironment-scoped fixture — e.g. a TempDir with a known-empty or\nknown-seeded data dir before the command can produce deterministic\noutput):\n\n- `robot/health.json.golden` — needs a seeded data dir with a stable\n  fixture index so the `last_indexed_at` / counts are scrubbable.\n- `robot/models_status.json.golden` — needs a pinned `CASS_DATA_DIR`\n  with a known model-cache state (empty vs installed) so `state`,\n  `next_step`, and per-file `size_match` are deterministic.\n- `robot/robot_docs.json.golden` — needs a topic-specific fixture\n  since the output is a large formatted doc string per topic.\n"

Discovery  - Parses ~/.ssh/config to find configured hosts\n  2. Probing    - Connects via SSH to check cass status and agent data\n  3. Selection  - Interactive selection of which hosts to configure\n  4. Install    - Installs cass on hosts without it (optional)\n  5. Indexing   - Runs `cass index` on remotes (optional)\n  6. Config     - Generates sources.toml entries\n  7. Sync       - Downloads session data to local machine (optional)\n\n## Flags Reference\n  --hosts <names>      Only configure these hosts (comma-separated SSH aliases)\n  --dry-run            Preview without making changes\n  --resume             Resume from ~/.cache/cass/setup_state.json\n  --non-interactive    Skip prompts, use auto-detected defaults\n  --skip-install       Don't install cass on remotes\n  --skip-index         Don't run remote indexing\n  --skip-sync          Don't sync after setup\n  --json               Output progress as JSON for scripting\n  --timeout <secs>     SSH connection timeout (default: 10)\n  --verbose            Show detailed progress\n\n## Non-Interactive Usage (Scripting)\n  cass sources setup --non-interactive --hosts css,csd\n  cass sources setup --non-interactive --hosts css --skip-install --skip-index\n  cass sources setup --json --hosts css  # JSON output for parsing\n\n## State and Resume\nState saved to ~/.cache/cass/setup_state.json on interruption.\nResume with: cass sources setup --resume\n\n## Generated Configuration\nThe wizard generates sources.toml entries like:\n  [[sources]]\n  name = \"css\"\n  type = \"ssh\"\n  host = \"css\"\n  paths = [\"~/.claude/projects\", \"~/.codex/sessions\"]\n  sync_schedule = \"manual\"\n  [[sources.path_mappings]]\n  from = \"/data/projects\"\n  to = \"/Users/username/projects\"\n\n## After Setup\n  cass search \"query\"       # Search across all sources\n  cass sources sync --all   # Sync latest data\n  cass sources list         # List configured sources\n\n## Troubleshooting\n  \"Host unreachable\": Verify SSH config with `ssh <host>` manually\n  \"Permission denied\": Load SSH key with `ssh-add ~/.ssh/id_rsa`\n  \"cargo not found\": Use --skip-install and install manually\n  \"Index taking too long\": Large histories take time; runs in background\n\n## Artifact Proofs\n  cass sources artifact-manifest --write --json\n  cass sources artifact-manifest --verify-existing --index-path /copy --expected-manifest /producer/evidence-bundle-manifest.json --json\nWrites evidence-bundle-manifest.json for the current lexical artifact.\nUse --index-path and --expected-manifest to verify a copied artifact before exchange.\n\n## Related Commands\n  cass sources list         List configured sources\n  cass sources sync         Sync data from sources\n  cass sources artifact-manifest  Write/verify lexical artifact proof\n  cass sources discover     Just discover hosts (no setup)\n  cass sources add          Manually add a source\n"

Existing\n//! `tests/e2e_filters.rs::stats_by_source_grouping` only verifies\n//! that `cass stats --by-source --json` emits a non-empty `by_source`\n//! array, NOT that `total == sum(by_source[*])`. A regression that\n//! double-counts in one path or drops a source would leave the\n//! existing test green while violating the invariant operators rely\n//! on.\n//!\n//! The MR archetype is **Inclusive (Pattern 5)**: T(stats_query) =\n//! stats_query + `--by-source`. Relation: `total == sum(by_source[*])`\n//! per metric. Even with a single source_id (the only kind reachable\n//! without a remote sync setup), this catches divergence between the\n//! two SQL paths — they MUST emit consistent counts for the same\n//! underlying canonical DB.\n\nuse assert_cmd::cargo::cargo_bin_cmd;\nuse std::fs;\nuse std::path::{Path, PathBuf};\n\nmod util;\nuse util::EnvGuard;\n\nstruct StatsFixture {\n    _tmp: tempfile::TempDir,\n    home: PathBuf,\n    codex_home: PathBuf,\n    data_dir: PathBuf,\n}\n\nimpl StatsFixture {\n    fn new() -> Self {\n        let tmp = tempfile::TempDir::new().unwrap();\n        let home = tmp.path().to_path_buf();\n        let codex_home = home.join(\".codex\");\n        let data_dir = home.join(\"cass_data\");\n        fs::create_dir_all(&data_dir).unwrap();\n\n        Self {\n            _tmp: tmp,\n            home,\n            codex_home,\n            data_dir,\n        }\n    }\n\n    fn env_guards(&self) -> (EnvGuard, EnvGuard) {\n        (\n            EnvGuard::set(\"HOME\", self.home.to_string_lossy().as_ref()),\n            EnvGuard::set(\"CODEX_HOME\", self.codex_home.to_string_lossy().as_ref()),\n        )\n    }\n\n    fn index_full(&self) {\n        cargo_bin_cmd!(\"cass\")\n            .args([\"index\", \"--full\", \"--data-dir\"])\n            .arg(&self.data_dir)\n            .env(\"CODEX_HOME\", &self.codex_home)\n            .env(\"HOME\", &self.home)\n            .env(\"CODING_AGENT_SEARCH_NO_UPDATE_PROMPT\", \"1\")\n            .env(\"CASS_IGNORE_SOURCES_CONFIG\", \"1\")\n            .assert()\n            .success();\n    }\n\n    fn stats_json(&self, by_source: bool) -> serde_json::Value {\n        let mut args: Vec<&str> = vec![\"stats\", \"--json\"];\n        if by_source {\n            args.push(\"--by-source\");\n        }\n        args.push(\"--data-dir\");\n        let data_dir_str = self.data_dir.to_str().expect(\"utf8 data dir\");\n        args.push(data_dir_str);\n\n        let output = cargo_bin_cmd!(\"cass\")\n            .args(&args)\n            .env(\"HOME\", &self.home)\n            .env(\"CODEX_HOME\", &self.codex_home)\n            .env(\"CODING_AGENT_SEARCH_NO_UPDATE_PROMPT\", \"1\")\n            .env(\"CASS_IGNORE_SOURCES_CONFIG\", \"1\")\n            .output()\n            .expect(\"run cass stats\");\n        assert!(\n            output.status.success(),\n            \"cass stats {args:?} exited non-zero: status={:?}\\nstdout:\\n{}\\nstderr:\\n{}\",\n            output.status,\n            String::from_utf8_lossy(&output.stdout),\n            String::from_utf8_lossy(&output.stderr),\n        );\n        serde_json::from_slice(&output.stdout).expect(\"cass stats --json output is valid JSON\")\n    }\n\n    fn seed(&self, day: &str, rollout: &str, content: &str, ts_millis: u64) {\n        let date_path = format!(\"2024/11/{day}\");\n        let filename = format!(\"rollout-{rollout}.jsonl\");\n        write_codex_session(&self.codex_home, &date_path, &filename, content, ts_millis);\n    }\n}\n\n/// Creates a Codex session JSONL file mirroring the helper used by\n/// tests/e2e_filters.rs::make_codex_session_at.

This is the first slice of the \"interactive latency stays sane while cass\n//! indexes in the background\" scenario called for by bead\n//! `coding_agent_session_search-d2qix`.

E2E test suites that spawn the `cass` binary via `assert_cmd` (or\n//! `std::process::Command`) and call `.wait()` / `.assert().success()`\n//! will block indefinitely when the child hangs. Under that failure\n//! mode the test harness produces *no* useful output — just a silent\n//! stall until the outer cargo-test timeout eventually kills the\n//! runner. Operators and CI consumers are left reconstructing what\n//! phase the child was in by guessing.\n//!\n//! This module provides [`spawn_with_timeout_or_diag`], a wrapper that\n//!   1. spawns a command and polls [`std::process::Child::try_wait`],\n//!   2. on success returns the normal [`std::process::Output`],\n//!   3. on timeout emits a structured diagnostic dump to stderr\n//!      (label, child PID, elapsed, optional `data_dir` listing, last\n//!      N bytes of stdout / stderr), kills the child, and panics with\n//!      a clear message.\n//!\n//! Tests in `tests/e2e_large_dataset.rs` and similar long-running\n//! suites can swap `.assert().success()` for this wrapper to convert\n//! a silent hang into a loud, diagnosable failure.\n\nuse std::io::Read;\nuse std::path::{Path, PathBuf};\nuse std::process::{Command, Output, Stdio};\nuse std::time::{Duration, Instant};\n\n/// How often we poll the child's exit status while waiting.\nconst POLL_INTERVAL: Duration = Duration::from_millis(50);\n\n/// How much of the child's streamed stdout/stderr to keep for the\n/// timeout-diagnostic dump.
