# BRIEFING — 2026-10-09T04:20:00Z

## Mission
Conduct Milestone M1 Gate Verification review and adversarial challenge for classifier/start frame refactoring, Kim Trọng safeguard, prompt synchronization, and workspace hygiene.

## 🔒 My Identity
- Archetype: reviewer_and_critic
- Roles: reviewer, critic
- Working directory: c:\Projects\KieuStory\.agents\teamwork\reviewer_m1_2
- Original parent: 97faf5e5-a830-491c-b78c-2af12175badf
- Milestone: M1 Gate Verification
- Instance: 2 of 2

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code directly
- Adversarial critic: actively check for integrity violations, hardcoded test results, facade implementations, bypassed tasks, fabricated logs, or self-certification
- Strictly follow project conventions and anti-dilution rules

- Conversation ID: 97faf5e5-a830-491c-b78c-2af12175badf
- Updated: 2026-10-09T04:20:00Z

## Review Scope
- **Files reviewed**:
  - `05_Production_Pipeline/production_orchestrator.py` (`classify_shot_take()`, `resolve_start_frame_v2()`, `resolve_start_frame()`)
  - `05_Production_Pipeline/antigravity_critic_gate.py` (3-tier architecture, Pydantic v2 schemas)
  - `episodes/ep01/prompts/muse_prompts.json` (11 modified entries)
  - `02_AI_Prompts/muse_ai_video_prompts.json` (synchronization check)
  - `02_AI_Prompts/gemini_banana_prompts.json` (character anchors)
  - `episodes/ep01/screenplay.md` (Scene 10 narrative & character actions)
  - `tests/test_critic_gate.py`, `tests/test_m2_hygiene.py`, `tests/test_tier1_features.py`
  - Upstream handoff: `.agents/teamwork/worker_m1_critic_1/handoff.md`
- **Interface contracts**: `.agents/teamwork/ORIGINAL_REQUEST.md`, `.agents/teamwork/orchestrator_1/PROJECT.md`
- **Review criteria**: Correctness, integrity, adversarial robustness, prompt sync, test suite validity

## Review Checklist
- **Items reviewed**:
  - `classify_shot_take()` and `resolve_start_frame_v2()`
  - Kim Trọng safeguard in `resolve_start_frame()`
  - 11 prompt entries in `ep01/prompts/muse_prompts.json` and master sync
  - `tests/test_m2_hygiene.py` (6/6 pass)
  - `tests/test_tier1_features.py` (65/65 pass)
  - `tests/test_critic_gate.py` (23/23 pass)
- **Verdict**: REQUEST_CHANGES
- **Unverified claims**:
  - Claim that all 11 prompt changes were corrections (REFUTED: 4 of them inverted Thúy Kiều shots to Kim Trọng)
  - Claim that tests verify start frame resolution under production conditions (REFUTED: tests passed `{}` instead of actual `shot_data`)

## Attack Surface
- **Hypotheses tested**:
  - H1: Take classification distinguishes cut vs continuous without hardcoding (CONFIRMED)
  - H2: Kim Trọng safeguard prevents Kiều face on Kim Trọng shots (CONFIRMED)
  - H3: Does the safeguard protect Thúy Kiều shots from Kim Trọng face leakage? (VULNERABILITY FOUND: No bilateral guard)
  - H4: Do all 11 modified prompt entries actually belong to Kim Trọng? (VULNERABILITY FOUND: Shots 03, 06, 11, 12 belong to Thúy Kiều)
  - H5: Do tests in `test_critic_gate.py` test actual prompt metadata? (VULNERABILITY FOUND: Tests pass `{}` and hide defect)

## Key Decisions Made
- Issued formal verdict `REQUEST_CHANGES` due to critical character contamination in Scene 10 (Kiều Pipa performance assigned Kim Trọng portrait) and vacuous test harness masking this defect.
