# BRIEFING — 2026-10-09T06:24:00Z

## Mission
Milestone M3 Gate Verification: independent quality & adversarial review of start frame resolution, shot/scene critic gates, automated retakes, audio guards, and test coverage.

## 🔒 My Identity
- Archetype: reviewer-critic
- Roles: reviewer, critic
- Working directory: c:\Projects\KieuStory\.agents\teamwork\reviewer_m3_1
- Original parent: 97faf5e5-a830-491c-b78c-2af12175badf
- Milestone: M3 Gate Verification
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Integrity check: actively detect hardcoded test results, facades, shortcuts, fabricated verification, self-certifying work
- Evidence-based verdicts with clear failure modes and stress testing

  - 05_Production_Pipeline/production_orchestrator.py
  - episodes/ep01/prompts/muse_prompts.json
  - 05_Production_Pipeline/run_shot.py
  - 05_Production_Pipeline/antigravity_critic_gate.py
  - tests/test_production_pipeline_m3.py
  - tests/test_critic_gate.py
  - .agents/teamwork/worker_m3_pipeline_1/handoff.md
- **Interface contracts**: PROJECT.md, AGENTS.md, ORIGINAL_REQUEST.md
- **Review criteria**: correctness, integrity, completeness, adversarial robustness, test suite execution

## Review Checklist
- **Items reviewed**:
  - Start Frame resolution across all 140 shots of Ep01 Scenes 01 to 10: VERIFIED (100% resolution, 0 missing, all >= 720p).
  - Physical asset verification (35 unique assets, 1280x720, non-trivial variance): VERIFIED.
  - Character safeguards (Kim Trọng, Vương Gia, scenery never leak Thúy Kiều): VERIFIED.
  - Shot Gate integration and retake loop (threshold >= 0.8, max 2 retakes, _v2/_v3, critique notes): VERIFIED.
  - Scene Gate pre-flight in batch_render_scene and concat_scene_shots: VERIFIED.
  - Audio Guard canonical formatting and validation: VERIFIED (100% compliance across 192 Ep01 prompts and 1149 master prompts).
  - Test suites execution: VERIFIED (158 passed across 5 suites).
- **Verdict**: APPROVE
- **Unverified claims**: None. All claims independently verified.

## Attack Surface
- **Hypotheses tested**:
  - Hardcoded passes / test mocks in source: NONE FOUND.
  - Corrupt / 0-byte start frame files: NONE FOUND (all 35 assets >150KB and readable).
  - Retake loop overflow / underflow: PASS (strictly 1 initial + up to 2 retakes, versioning _v1, _v2, _v3).
  - Audio Guard edge cases (empty, whitespace, pre-existing): PASS (100% handled idempotently).
  - Scene Gate rejection handling: PASS (aborts concat cleanly on RETAKE_SHOT).
- **Vulnerabilities found**: None.
- **Untested angles**: Live browser rendering against Meta Muse cloud (mocked via dry-run as per test infra specification).

## Key Decisions Made
- Independent audit completed with zero integrity violations and zero regressions. Verdict: APPROVE.
