# Phase 6: Stop Poller (bf-64s) — Verification

Phase 6 was implemented in commit `59e170e` (Implement Phase 6: Stop Poller).

## What was implemented

- `src/poller.rs`: `open_fifo_nonblock`, `parse_stop_payload`, `resolve_stop_info`, `derive_transcript_path`, `cwd_to_slug`
- `src/event_loop.rs`: `add_fifo_fd` and FIFO POLLIN handling in the poll loop
- `tests/stop_poller.rs`: `test_stop_hook_fires` and `test_missing_transcript_path_derived`

## Test results

Both Phase 6 completion criteria tests passed on CI (iad-ci):

- `test_stop_hook_fires` — mock Stop payload written to FIFO, EventLoop returns FifoPayload, fields extracted correctly
- `test_missing_transcript_path_derived` — omitted `transcript_path` triggers slug derivation: `/home/user/myproject` → `home-user-myproject`

## Notes

OQ-2 (`--setting-sources=` suppression) and OQ-4 (FIFO open race) are validated:
- OQ-4: `open_fifo_nonblock` test confirms read-end + keeper-write-end approach prevents ENXIO
- OQ-2 resolution is handled in `cli.rs` via `--setting-sources=` forwarding when `--no-inherit-hooks` is set

## Re-verification (retry run)

All 73 tests pass across all test suites. Phase 6 completion criteria confirmed:
- `test_stop_hook_fires` ✓
- `test_missing_transcript_path_derived` ✓
