# Bead needle-b8fv: Transcript Reading Already Implemented

## Task Summary
The bead requested extending the reflect strand's Gather phase to read Claude Code session transcripts.

## Finding
The functionality is **already fully implemented** in the codebase:

### Implemented Components

1. **src/transcript/mod.rs** - Complete transcript module
   - `TranscriptDiscovery` - discovers transcripts from `~/.claude/projects/<project-name>/`
   - `derive_project_name()` - maps workspace path to Claude project directory name
   - `parse_transcript()` - stream-parses JSONL entries into structured types
   - `ActionOutcome` - captures tool_call → tool_result sequences
   - `detect_decisions()` - extracts ADR-style decisions from thinking blocks

2. **src/learning/mod.rs** - Learning types
   - `TranscriptPattern` - pattern type for transcript-derived learnings (lines 768-868)

3. **src/strand/reflect.rs** - Integration
   - `extract_from_transcripts()` (lines 964-1175) - main extraction logic
   - Called during Gather phase (lines 441-454)
   - Graceful error handling with `unwrap_or_else()`
   - Transcript entries merged into consolidation pipeline (lines 541-586)

### Configuration Options (src/config/mod.rs)

- `transcript_recency_days` - filter by recency
- `transcript_max_sessions` - limit number of sessions
- `drift_enabled` - drift detection across sessions
- `adr_enabled` - ADR decision extraction

### Verification

All tests pass:
- 13 transcript module tests
- 23 reflect strand tests
- Integration verified by code inspection

## Conclusion

No implementation work was required. The bead described work that was already completed in a prior session (likely needle-ry21 based on the OTLP commit history).
