# BRIEFING — 2026-10-09T05:32:00Z

## Mission
Milestone M1 Iteration 3 Gate Verification (Reviewer 2 / Adversarial Critic): independently review and stress-test remediation fixes in production_orchestrator.py and tests/test_critic_gate.py.

## 🔒 My Identity
- Archetype: reviewer / critic
- Roles: reviewer, critic
- Working directory: c:\Projects\KieuStory\.agents\teamwork\reviewer_m1_iter3_2
- Original parent: 97faf5e5-a830-491c-b78c-2af12175badf
- Milestone: M1 Iteration 3
- Instance: 2 of 2

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Check integrity violations (hardcoding, shortcuts, facade implementations)
- Must follow 5-Component Handoff Protocol
- Evidence-based adversarial evaluation

## Review Scope
- **Files to review**:
  - `05_Production_Pipeline/production_orchestrator.py`
  - `tests/test_critic_gate.py`
- **Interface contracts**:
  - `.agents/teamwork/orchestrator_1/PROJECT.md`
  - `.agents/teamwork/ORIGINAL_REQUEST.md`
  - Previous critic findings in `.agents/teamwork/reviewer_m1_iter2_2/handoff.md`
- **Review criteria**: correctness, completeness, anti-regression, adversarial stress testing, integrity

## Key Decisions Made
- Confirmed surgical modifications in `production_orchestrator.py`:
  - `get_character_anchor()` Thúy Vân text fallback present.
  - `resolve_character_portrait_from_anchor()` attendant ordering (`tieu_dong`, `quan_gia_kim_trong`) evaluated before `kim_trong`.
  - `resolve_start_frame()` title-only solo designations override compound anchor deactivation.
  - Step C violation check includes `is_thuy_van`.
  - Step D has explicit `is_thuy_van` override branch and missing-path fallback.
- Confirmed test hardening in `tests/test_critic_gate.py` (tests 5a, 5b, 6a, 6b, 7).
- Executed all verification test suites: 100% PASS (155/155 tests across all test suites).
- Executed standalone adversarial edge-case probes: 5/5 PASSED.
- Verified absence of integrity violations, hardcoded shot IDs, or mock facades.
- Verdict: APPROVE.

  - `tests/test_critic_gate.py` (lines 530-625)
  - `tests/test_m1_challenger2_probe.py`
  - `tests/test_tier1_features.py`
  - `tests/test_adversarial_deep_probe.py`
  - `tests/test_m2_hygiene.py`
- **Verdict**: APPROVE
- **Unverified claims**: None. All claims independently verified.

## Attack Surface
- **Hypotheses tested**:
  - Thúy Vân safeguard leakage via Step C / Step D / fallback (TESTED - PASSED)
  - Compound anchor deactivation via joint anchors with solo title (TESTED - PASSED)
  - Attendant substring shadowing (`tieu_dong_kim_trong`, `quan_gia_kim_trong`) (TESTED - PASSED)
  - Cinematic Cut prevention of `prev_tail` frame returns (TESTED - PASSED)
  - Integrity violation / hardcoded shot checks (TESTED - PASSED)
- **Vulnerabilities found**: None. All prior vulnerabilities remediated.
- **Untested angles**: None within Milestone M1 scope.
