# BRIEFING — 2026-10-04T12:58:00Z

## Mission
Perform an objective, adversarial asset and specification conformance review for Milestone 1 (Cocos VFX atlases, normal maps, ASTC headers, 10 monsters, 6 classes, and E2E test suite).

## 🔒 My Identity
- Archetype: reviewer_and_adversarial_critic
- Roles: reviewer, critic
- Working directory: c:\Projects\FreeExile\.agents\teamwork\reviewer_m1_2
- Original parent: 34037784-62e1-41f8-bfe6-912696fdec14
- Milestone: Milestone 1
- Instance: reviewer_m1_2

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Check for integrity violations: hardcoded test results, dummy/facade implementations, shortcuts bypassing the task, fabricated outputs, self-certifying work
- Verify binary assets, normal map physics/math, Apple Metal ASTC specs, 8-directional monster rigging, and Song Binh weapon pair scaffolding
- Follow 5-component handoff report structure (Observation, Logic Chain, Caveats, Conclusion, Verification Method)

## Review Scope
- **Files to review**:
  - `client/cocos/assets/resources/vfx/savage_primal_skills_vfx_atlas.png`
  - `client/cocos/assets/resources/vfx/savage_primal_skills_vfx_atlas_normal.png`
  - `client/cocos/assets/resources/vfx/savage_primal_skills_vfx_atlas.json`
  - `client/cocos/assets/resources/vfx/savage_primal_skills_vfx_atlas.astc`
  - `client/cocos/assets/resources/monsters/archetypes/`
  - `client/cocos/assets/resources/characters/`
  - `tests/e2e_cocos/test_vfx_texture_atlas_pipeline_e2e.py`
  - `tools/asset_pipeline/produce_all_missing_skills_vfx.py`
  - `tools/asset_pipeline/pbr_texture_synthesizer.py`
  - `tools/asset_pipeline/astc_compressor.py`
  - `tools/asset_pipeline/monster_character_pipeline_scaffold.py`
- **Interface contracts**: PROJECT.md, SCOPE.md, ANIMATION_AND_VFX_PIPELINE_STANDARDS.md
- **Review criteria**: Correctness, integrity, quality, Apple Metal & Cocos specs, 12 active skills + 5 support + evasion, 10 monsters (8 dirs), 6 classes (Song Binh).

## Review Checklist
- **Items reviewed**:
  - VFX Albedo texture: 2048x2048 PoT, 8-iteration dilation padding (VERIFIED PASS)
  - VFX Tangent normal map: Sobel BGR layout, Blue mean 254.69 > 128.0, unit vectors length 1.0000 (VERIFIED PASS)
  - VFX Manifest JSON: 12 active skills + 5 sigils + 1 evasion, 46 clip keys, pivot [0.5, 0.90] (VERIFIED PASS)
  - ASTC container: canonical 16-byte header, 4x4 block, 4,194,320 bytes (VERIFIED PASS)
  - 10 monster archetypes: 8 directions present, pipeline configs present (DEFECT: 74% frames have V > 1.0 up to 3.75)
  - 6 exile classes: 8 directions, Song Binh config present (DEFECT: 86% frames have V > 1.0 up to 7.5)
  - Test suite hygiene: test_vfx_texture_atlas_pipeline_e2e.py is 575 lines (DEFECT: exceeds 500-line hard cap)
- **Verdict**: REQUEST_CHANGES
- **Unverified claims**: None (all claims verified directly through code and image analysis)

## Attack Surface
- **Hypotheses tested**:
  - H1: UV coordinate boundedness across all manifests -> FAILED on monster & character manifests ($V$ up to 7.5).
  - H2: SHA-256 asset parity across targets -> PASSED (Cocos, WebApp, and approved are in parity).
  - H3: Tangent normal map vector unit length -> PASSED (1.0000 mean length, no NaN/Inf).
  - H4: Codebase hygiene hard caps -> FAILED on test file (575 lines > 500 lines).
- **Vulnerabilities found**:
  - Critical: Monster/Character scaffolding UV calculation overflow ($V \in [0.0, 7.5]$).
  - Critical: Hygiene limit breach in E2E test file (575 lines).
  - Major: Test suite shallow check in `test_t1_monster_and_character_scaffolding_structure`.
- **Untested angles**: None.

## Key Decisions Made
- Issued verdict REQUEST_CHANGES due to 2 Critical findings (UV coordinate overflow and Hard Cap line count breach) and 1 Major finding (shallow test assertion).
