# BRIEFING — 2026-10-09T03:32:15Z

## Mission
Conduct independent adversarial review and verification for Milestone M2 Iteration 2 Gate Verification.

## 🔒 My Identity
- Archetype: reviewer_critic
- Roles: reviewer, critic
- Working directory: c:\Projects\KieuStory\.agents\teamwork\reviewer_m2_iter2_2
- Original parent: 97faf5e5-a830-491c-b78c-2af12175badf
- Milestone: M2 Iteration 2 Gate Verification
- Instance: 2 of 2

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Check for integrity violations (hardcoded test results, dummy implementations, shortcuts, fabricated verification, self-certifying work)
- Output formal verdict (APPROVE or REQUEST_CHANGES)
- Communicate via send_message to parent orchestrator

## Review Scope
- **Files to review**:
  - `04_Assets/characters/` (portrait integrity, 62 files, 14 core PNGs)
  - `04_Assets/archive/ep01_legacy_v1/` (184 legacy videos, >2.0GB, ftyp headers)
  - Non-Ep01 assets (118 videos, 67 keyframe dirs, 10 root keyframe files)
  - `04_Assets/archive/README.md` (>9KB legal IP doc)
  - `tests/test_m2_hygiene.py`
  - `.agents/teamwork/worker_m2_hygiene_2/handoff.md`
- **Interface contracts**: `PROJECT.md`, `ORIGINAL_REQUEST.md`
- **Review criteria**: correctness, completeness, integrity, invariant preservation

## Review Checklist
- **Items reviewed**:
  - `04_Assets/characters/` (62 files, 0 zero-byte, 14 core PNGs format/dimension checked via PIL)
  - `04_Assets/archive/ep01_legacy_v1/` (184 MP4 files, 2.095 GB, all valid ftyp headers, plus README.md and exports/ folder)
  - `04_Assets/videos/` (118 non-Ep01 videos, 0 Ep01 videos)
  - `04_Assets/keyframes/` (67 non-Ep01 dirs, 0 Ep01 dirs, 10 root keyframe files, 0 Ep01 root files)
  - `04_Assets/archive/ep01_legacy_v1/README.md` (9,931 bytes, complete legal and human agency citations)
  - `tests/test_m2_hygiene.py` (6/6 PASS in 0.14s)
  - `05_Production_Pipeline/run_shot.py` & `muse_invpw_driver.py` (hardened against eager dir creation)
  - Process environment (0 rogue processes running)
- **Verdict**: APPROVE
- **Unverified claims**: None. All upstream claims empirically reproduced and verified.

## Attack Surface
- **Hypotheses tested**:
  - H1: Are there symlinks/junctions masking duplicate files? Tested -> 0 symlinks found.
  - H2: Are there case-insensitive variations of Ep01 remaining? Tested -> 0 found.
  - H3: Are there hidden dotfiles in asset dirs? Tested -> 0 found.
  - H4: Are any archived or non-Ep01 video headers corrupted? Tested -> 0 invalid ftyp headers across all 184 + 118 files.
  - H5: Are any essential Ep01 screenplay or manifest files deleted? Tested -> All 6 files intact.
  - H6: Are there rogue background processes writing to disk? Tested -> 0 rogue processes.
  - H7: Did tests contain hardcoded dummies or shortcuts? Tested -> Genuine live filesystem tests.
- **Vulnerabilities found**: None. Remediated completely by Worker 2.
- **Untested angles**: None within Milestone M2 scope.

## Key Decisions Made
- Confirmed zero integrity violations.
- Issued formal verdict: APPROVE.
