Last visited: 2026-10-09T06:27:00Z

## Status: IN_PROGRESS (Synthesizing Handoff)

### Checklist:
- [x] 1. Read mandatory context files:
  - [x] `.agents/teamwork/ORIGINAL_REQUEST.md`
  - [x] `.agents/teamwork/orchestrator_1/PROJECT.md`
  - [x] `.agents/teamwork/worker_m3_pipeline_1/handoff.md`
- [x] 2. Audio Guard Empirical Verification:
  - [x] Inspect all 192 prompts in `episodes/ep01/prompts/muse_prompts.json` for canonical Audio Guard (188 exact canonical, 4 legacy/non-canonical)
  - [x] Test `production_orchestrator.py` rejects prompt without Audio Guard (Disproven: auto-appends and does not reject; `validate_audio_guard` is unused)
- [x] 3. MUSE_DRY_RUN Pipeline Execution Verification:
  - [x] Run dry-run batch render on a multi-shot scene with `enable_critic=True` (FAILS at shot 1 due to frozen video detection on static color bar)
  - [x] Run dry-run batch render with `enable_critic=False` (PASSES: generates 10s MP4s and extracts tail frame 239)
  - [x] Verify Head-Tail chaining (tail frame 239 -> next shot start frame verified on continuous take)
- [x] 4. Scene Gate Pre-flight Behavior Verification:
  - [x] Test missing video blocks concat (PASS)
  - [x] Test RETAKE_SHOT blocks concat (PASS)
  - [x] Test unapproved score bypass with APPLY_COLOR_MATCH / TRIM_STATIC (FAIL: bypasses gate and stitches unapproved master)
- [x] 5. Test Suite Execution:
  - [x] Run `pytest tests/test_production_pipeline_m3.py -v` (16 passed)
  - [x] Run `pytest tests/test_m2_hygiene.py -v` (6 passed)
  - [x] Run `pytest tests/test_critic_gate.py -v` (30 passed)
  - [x] Run `pytest tests/test_m1_challenger2_probe.py -v` (41 passed)
  - [x] Run `pytest tests/test_tier1_features.py -k "not test_render"` (65 passed)
  - [x] Run `pytest tests/test_m3_challenger1_probe.py -v` (1 failed: `ep01_scene03_shot05` Thúy Vân leaks Thúy Kiều)
- [ ] 6. Synthesize Challenge Report & Handoff:
  - [ ] Write `handoff.md` with 5 components and verdict: REQUEST_CHANGES
  - [ ] Update `BRIEFING.md`
  - [ ] Send message to parent orchestrator
