# BRIEFING — 2026-10-09T07:42:00Z

## Mission
Milestone M3 Iteration 3 Gate Verification: Verify prompt anchor fixes, classify_shot_take actor switch hardening, resolve_start_frame_v2 bilateral defense-in-depth, batch_render_scene gate check, and test suite execution.

## 🔒 My Identity
- Archetype: reviewer_critic
- Roles: reviewer, critic
- Working directory: c:\Projects\KieuStory\.agents\teamwork\reviewer_m3_iter3_1
- Original parent: 97faf5e5-a830-491c-b78c-2af12175badf
- Milestone: M3 Iteration 3
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Actively check for integrity violations: hardcoded results, facades, shortcuts, fabricated logs, self-certifying work
- Evidence-based review and adversarial challenge
- Send completion message to parent orchestrator

## Review Scope
- **Files to review**:
  - `02_AI_Prompts/gemini_banana_prompts.json`
  - `episodes/ep01/prompts/banana_prompts.json`
  - `05_Production_Pipeline/production_orchestrator.py`
  - `tests/test_m3_challenger1_probe.py`
  - `tests/test_production_pipeline_m3.py`
  - `tests/test_critic_gate.py`
- **Interface contracts**:
  - `c:\Projects\KieuStory\.agents\teamwork\ORIGINAL_REQUEST.md`
  - `c:\Projects\KieuStory\.agents\teamwork\orchestrator_1\PROJECT.md`
  - `c:\Projects\KieuStory\.agents\teamwork\worker_m3_remediation_3\handoff.md`
- **Review criteria**: Correctness, integrity, bilateral defense-in-depth, test verification, regression prevention

## Review Checklist
- **Items reviewed**:
  - Dual-bucket prompt anchor synchronization in `02_AI_Prompts/gemini_banana_prompts.json` and `episodes/ep01/prompts/banana_prompts.json`: VERIFIED (Thuy Van, Vuong Ong, Thuy Kieu Maiden).
  - Hardened `classify_shot_take` in `05_Production_Pipeline/production_orchestrator.py`: VERIFIED (Character group comparison, metadata passing, textual actor switch detection).
  - Bilateral defense-in-depth in `resolve_start_frame_v2` Step 1: VERIFIED (Safeguards prevent tail frame leaks across character boundaries).
  - Tightened `batch_render_scene` gate check (line 972): VERIFIED (`if not scene_verdict.approved: return False`).
  - Integrity violation checks: VERIFIED (Zero hardcoding, zero facade implementations, zero fabricated logs).
  - Test suites execution: VERIFIED (12/12 test_m3_challenger1_probe, 16/16 test_production_pipeline_m3, 30/30 test_critic_gate, and 427/427 repository-wide tests passed).
- **Verdict**: APPROVE
- **Unverified claims**: None remaining. All claims independently verified.

## Attack Surface
- **Hypotheses tested**:
  1. H1: Adjacent shot actor switches (Thuy Van -> Thuy Kieu in Scene 03 Shot 05->06) leak tail frame if clean_frame_239.jpg exists on disk. Result: REJECTED (Defense-in-depth strictly overrides to CINEMATIC_CUT and resolves Thuy Kieu portrait).
  2. H2: Textual actor switch detection bypasses character reference checks. Result: REJECTED (Checked and verified as supplementary hard gate).
  3. H3: Corrupted prompt metadata bypasses character portrait resolution. Result: REJECTED (Bilateral overrides enforce correct portrait).
  4. H4: Unapproved scene verdict with overall_score >= 0.8 bypasses batch_render_scene gate. Result: REJECTED (Line 972 strictly halts on not scene_verdict.approved).
- **Vulnerabilities found**: None in current implementation.
- **Untested angles**: Hardware-specific Muse.ai live browser automation (requires credentials and human-in-the-loop session).

## Key Decisions Made
- Confirmed all M3 Iteration 3 remediation criteria are fully satisfied.
- Issued formal review verdict: APPROVE.
