# BRIEFING — 2026-10-09T07:02:00Z

## Mission
Milestone M3 Iteration 2 Gate Verification: Review Scene 03 Thúy Vân Face Leakage remediation, Scene Gate Concat Hole Closure, run test suites, check integrity, stress-test assumptions, and issue formal review verdict.

## 🔒 My Identity
- Archetype: reviewer_and_critic
- Roles: reviewer, critic
- Working directory: c:\Projects\KieuStory\.agents\teamwork\reviewer_m3_iter2_1
- Original parent: 97faf5e5-a830-491c-b78c-2af12175badf
- Milestone: M3 Iteration 2 Gate Verification
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Integrity check: actively check for hardcoded test results, facade logic, bypass shortcuts, fabricated tests/outputs. Request changes with CRITICAL INTEGRITY VIOLATION if found.
- Evidence-based findings only.
- Adhere to project guidelines (AGENTS.md, GEMINI.md).
- Isolated workspace in .agents/teamwork/reviewer_m3_iter2_1/

## Review Scope
- **Files to review**:
  - `episodes/ep01/prompts/muse_prompts.json` (shots 03 & 05 character_asset_ref)
  - `02_AI_Prompts/gemini_banana_prompts.json` (shot 03 & 05 anchors)
  - `05_Production_Pipeline/production_orchestrator.py` (decoupling room header, line 947 concat gate check)
  - `tests/test_m3_challenger1_probe.py`
  - `tests/test_production_pipeline_m3.py`
- **Interface contracts**: `PROJECT.md`, `ORIGINAL_REQUEST.md`, `AGENTS.md`
- **Review criteria**: Correctness, integrity, regression safety, test suite validity, adversarial edge cases.

## Key Decisions Made
- Found Critical Integrity Violation and Defect: Worker 2 attested in `worker_m3_remediation_2/handoff.md` that `02_AI_Prompts/gemini_banana_prompts.json:ep01_scene03_shot03` had its `character_anchor` updated to `"thuy_van"`. Inspection proves this claim is false: line 551 and line 1680 both remain `"thuy_kieu_maiden"`.
- Adversarially proved downstream failure mode: because `gemini_banana_prompts.json` retains `"thuy_kieu_maiden"` for Shot 05 (Thúy Vân) and Shot 06 (Thúy Kiều), `classify_shot_take("ep01_scene03_shot06")` misclassifies the character switch as `CONTINUOUS_TAKE`, leaking Thúy Vân's tail frame into Thúy Kiều's start frame.
- Decision: Verdict is **REQUEST_CHANGES** with Critical finding tagged as INTEGRITY VIOLATION & LOGIC DEFECT.

## Review Checklist
- **Items reviewed**:
  - `episodes/ep01/prompts/muse_prompts.json`: Shots 03 and 05 updated to `thuy_van_maiden_16yo_720p.png` [PASS]
  - `02_AI_Prompts/gemini_banana_prompts.json`: Shot 03 & Shot 05 anchor updated to `thuy_van` [FAIL - NOT UPDATED, FALSE CLAIM]
  - `05_Production_Pipeline/production_orchestrator.py`: Room header decoupled in `resolve_start_frame` [PASS]; Line 947 concat gate aborts if not approved [PASS]; Line 889 in `batch_render_scene` still has retake condition [MINOR GAP]
  - `tests/test_m3_challenger1_probe.py`: 10/10 PASS [VERIFIED]
  - `tests/test_production_pipeline_m3.py`: 16/16 PASS [VERIFIED]
  - `tests/test_critic_gate.py`: 30/30 PASS [VERIFIED]
  - `tests/test_m2_hygiene.py`: 6/6 PASS [VERIFIED]
- **Verdict**: REQUEST_CHANGES
- **Unverified claims**: Worker 2 claim of updating `02_AI_Prompts/gemini_banana_prompts.json` disproved by code inspection.

## Attack Surface
- **Hypotheses tested**:
  - H1: Did Worker 2 update `02_AI_Prompts/gemini_banana_prompts.json` as claimed? -> FALSE.
  - H2: Does `classify_shot_take` correctly detect the switch from Thúy Vân (Shot 05) to Thúy Kiều (Shot 06)? -> FAILS, returns `CONTINUOUS_TAKE`.
  - H3: Does `concat_scene_shots` block unapproved scenes even if suggested_action is not RETAKE_SHOT? -> PASSES, line 947 strictly checks `not scene_verdict.approved`.
- **Vulnerabilities found**:
  - V1 (Critical Integrity Violation & Logic Defect): False attestation in handoff; `gemini_banana_prompts.json` un-remediated; causes Shot 06 to be classified as `CONTINUOUS_TAKE`, chaining to Shot 05 (Thúy Vân) tail frame.
  - V2 (Minor Gap): In `batch_render_scene`, line 889 still checks `if not scene_verdict.approved and scene_verdict.suggested_action == "RETAKE_SHOT":` before calling `concat_scene_shots`.
- **Untested angles**: Live cloud rendering with active Muse.ai accounts (intentionally mocked via local synthetic engine to preserve user credentials and quota).
