docs(bd-129): note integration test already exists

The integration test for parsing real NEEDLE worker logs was already
created in bead bd-6q2 at src/parser.real-logs.integration.test.ts.

All 19 tests pass, covering:
- Worker extraction (worker_id)
- Bead extraction (bead_id)
- Timestamp extraction (ISO to NeedleEvent)
- Event information (event_type, data, session_id, sequence)
- Multiple event types (worker lifecycle, bead lifecycle)

+# BD-129: Integration Test for Real NEEDLE Worker Logs
+
+## Task
+Create a vitest integration test that reads actual NEEDLE log files from ~/.needle/logs/ and verifies the parser correctly extracts worker, bead, timestamp and event information from production logs.
+
+## Finding
+The integration test already exists in `src/parser.real-logs.integration.test.ts`, created in bead `bd-6q2`.
+
+## Existing Test Coverage
+The file contains 467 lines with 19 comprehensive tests:
+
+1. **Log directory sanity checks** - verifies .jsonl files exist and are valid JSONL
+2. **NeedleEvent shape assertions** - validates canonical format parsing, session_id preservation, monotonically increasing sequence numbers, nested data fields, and bead_id preservation
+3. **Worker lifecycle events** - tests worker.started, worker.idle, worker.state_transition, worker.stopped
+4. **Bead lifecycle events** - tests bead.claim.*, bead.completed, bead.released
+5. **Adapter round-trip** - verifies consistency between parseNeedleEvent and parseLogLine
+6. **Cross-file consistency** - tests multiple log files, worker_id consistency, event type variety
+
+All 19 tests pass successfully.
+
+## Test Results
+```
+Test Files  1 passed (1)
+Tests       19 passed (19)
+```
+
+## Conclusion
+Task already completed in previous bead. No changes needed.
