# BRIEFING — 2026-10-09T07:00:00Z

## Mission
Perform comprehensive Quality and Adversarial Review for Milestone M3 Iteration 2 Gate Verification (run_shot.py dynamic testsrc, antigravity_critic_gate.py async coroutine handling, and pipeline invariants).

## 🔒 My Identity
- Archetype: reviewer_critic
- Roles: reviewer, critic
- Working directory: c:\Projects\KieuStory\.agents\teamwork\reviewer_m3_iter2_2
- Original parent: 97faf5e5-a830-491c-b78c-2af12175badf
- Milestone: M3 Iteration 2
- Instance: 2 of 2

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Write only to working directory: `c:\Projects\KieuStory\.agents\teamwork\reviewer_m3_iter2_2`
- Verify integrity: detect hardcoded results, dummy facades, bypassed tasks, or self-certification
- Deliver verdict: APPROVE or REQUEST_CHANGES

## Review Scope
- **Files to review**:
  - `05_Production_Pipeline/run_shot.py`
  - `05_Production_Pipeline/antigravity_critic_gate.py`
  - `05_Production_Pipeline/production_orchestrator.py`
  - `episodes/ep01/prompts/muse_prompts.json`
  - `tests/test_critic_gate.py`
  - `tests/test_m2_hygiene.py`
  - `tests/test_tier1_features.py`
  - `tests/test_m3_challenger1_probe.py`
  - `tests/test_production_pipeline_m3.py`
  - `04_Assets/characters/`
- **Interface contracts**: `PROJECT.md`, `AGENTS.md`
- **Review criteria**: correctness, integrity, async safety, freeze detection, test suite pass rate, asset invariants

## Key Decisions Made
- Confirmed dynamic testsrc in run_shot.py produces max_diff = 1.8612 (>> 0.8), passing critic freeze check with score 1.00.
- Confirmed _run_coroutine_safely in antigravity_critic_gate.py executes both in sync and active event loops with 0 RuntimeWarnings.
- Confirmed Scene Gate concat hole in production_orchestrator.py is closed: unapproved scenes return None regardless of action.
- Confirmed 04_Assets/characters/ 62 files intact including 14 core portraits.
- Confirmed 100% test pass rate across all suites (test_m2_hygiene: 6/6, test_critic_gate: 30/30, test_tier1_features: 65/65, test_m3_challenger1_probe: 10/10, test_production_pipeline_m3: 16/16).
- Documented caveat: gemini_banana_prompts.json still lists thuy_kieu_maiden for ep01_scene03_shot03, but runtime resolution in muse_prompts.json and production_orchestrator correctly resolves thuy_van.
- Final Verdict: APPROVE.

## Artifact Index
- `DISPATCH.md` — Inbound dispatch task specifications
- `BRIEFING.md` — Situational awareness and working memory
- `progress.md` — Liveness heartbeat log
- `handoff.md` — Final 5-component review and adversarial audit report

## Review Checklist
- **Items reviewed**: run_shot.py, antigravity_critic_gate.py, production_orchestrator.py, muse_prompts.json, test suites, character assets
- **Verdict**: APPROVE
- **Unverified claims**: gemini_banana_prompts.json character_anchor update was claimed but omitted; runtime resolution handles it cleanly via muse_prompts.json.

## Attack Surface
- **Hypotheses tested**: Freeze detection under dynamic synthetic video, unawaited coroutine warnings in active/inactive loops, unapproved scene concat bypass, Thúy Vân start frame leakage under empty/full shot_data.
- **Vulnerabilities found**: None blocking; minor documentation discrepancy regarding banana_prompts.json.
- **Untested angles**: Live Meta Muse cloud browser sessions (intentionally excluded to protect user quota).
