# BRIEFING — 2026-10-09T06:22:30Z

## Mission
Milestone M3 Gate Verification and Adversarial Review for KieuStory production pipeline.

## 🔒 My Identity
- Archetype: reviewer & critic
- Roles: reviewer, critic
- Working directory: c:\Projects\KieuStory\.agents\teamwork\reviewer_m3_2
- Original parent: 97faf5e5-a830-491c-b78c-2af12175badf
- Milestone: M3 Gate Verification
- Instance: 2 of 2

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Check for integrity violations (hardcoded test results, mock facade, bypasses)
- Zero dilution, project isolation: KieuStory
- Write only to own directory: c:\Projects\KieuStory\.agents\teamwork\reviewer_m3_2\

## Review Scope
- **Files to review**:
  - 05_Production_Pipeline/run_shot.py
  - 05_Production_Pipeline/production_orchestrator.py
  - tests/test_production_pipeline_m3.py
  - tests/test_m2_hygiene.py
  - 04_Assets/keyframes/
  - 04_Assets/characters/
- **Interface contracts**: c:\Projects\KieuStory\.agents\teamwork\orchestrator_1\PROJECT.md
- **Review criteria**: Correctness, code quality, regression safety, M2 hygiene invariants, Character Bible invariants, integrity checks

## Review Checklist
- **Items reviewed**:
  - M2 hygiene invariants (0 rogue ep01 keyframe dirs, 0 ep01 root files, 67 non-ep01 dirs, 10 non-ep01 files)
  - Character Bible invariants (62 portraits intact, git status clean on 04_Assets/characters/)
  - MUSE_DRY_RUN mock engine implementation in run_shot.py
  - Audio Guard canonical formatting and enforcement
  - Shot Gate & automated retake loop in production_orchestrator.py
  - Scene Gate pre-flight verification in production_orchestrator.py
  - 100% Start Frame resolution across all 140 shots (Scenes 01-10)
  - Full test suites: test_production_pipeline_m3.py (16 passed), test_m2_hygiene.py (6 passed), test_critic_gate.py (30 passed), test_m1_challenger2_probe.py (41 passed), test_tier1_features.py (65 passed)
- **Verdict**: APPROVE
- **Unverified claims**: None. All claims independently reproduced and verified.

## Attack Surface
- **Hypotheses tested**:
  - Malicious Thuy Kieu prompt asset injection on Kim Trong, Vuong Ong, Vuong Quan, Thuy Van: blocked and overridden.
  - Reverse injection (Kim Trong on Thuy Kieu): blocked and overridden.
  - Attendant substring shadowing (tieu dong, quan gia): properly resolved before main character matching.
  - Version hole resolution (_v1, _v3): resolved correctly to _v4.
  - In-place cleanup of dry-run test artifacts: confirmed 100% clean.
- **Vulnerabilities found**: None. System is resilient and hardened.
- **Untested angles**: Live browser cloud rendering with Meta Muse session (out of scope for local automated testing, covered by MUSE_DRY_RUN).

## Key Decisions Made
- Confirmed zero integrity violations.
- Verified 100% of 140 start frames exist, read properly with OpenCV, and meet >= 720p dimensions.
- Verified test suite pass rate: 100% with zero regressions.
- Issued formal review verdict: APPROVE.
