# BRIEFING — 2026-10-01T22:42:00Z

## Mission
Review all new assets across M3 (Critical), M4 (High), M5 (Med/Low) in client/webapp/assets/ for technical compliance, visual integrity, and adversarial resilience.

## 🔒 My Identity
- Archetype: reviewer_critic

- Working directory: c:/Projects/FreeExile/.agents/teamwork/reviewer_assets/
- Original parent: 57f2e6be-0ed4-44c4-b348-12dbe4c5bd20
- Milestone: M3-M5 Asset Review
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Thoroughly check for integrity violations: hardcoded results, facades, dummy placeholders, skipped verification
- Strict verification: 100% 2^n texture dimensions, normal map tangent-space B mean > 128, file size budgets (Atlas <= 2MB, UI icon <= 150KB, Map tile <= 50KB)
- Run all verification scripts and unit/e2e test suites
- Explicit verdict: APPROVE or REQUEST_CHANGES

## Review Scope
- **Files to review**: `client/webapp/assets/` (animations, skills, savage_vfx, ui, map, characters, currencies, loading, banners)
- **Interface contracts**: `docs/standards/ENGINEERING_STANDARDS_2026.md`, `docs/standards/DESIGN_PIPELINE_AND_CROSS_DEPT_WORKFLOW.md`, `ORIGINAL_REQUEST.md` (2026-10-01T22:03:34Z)
- **Review criteria**: 2^n dimensions, tangent-space normal maps (B > 128), size budgets, sprite atlas format (albedo, normal, manifest JSON), visual integrity, adversarial integrity

## Review Checklist
- **Items reviewed**:
  - M3 Critical: 14 Mob/Boss animation packages (albedo + normal + manifest), 15 Skill atlases (5 classes x 3 skills) with Ngũ Hành palettes, 3 Combat VFX packages.
  - M4 High: 6 Passive tree nodes & constellation bg, 10 Dungeon & Arena tiles + normals, 5 new NPCs (avatar, portrait, standee, standee normal).
  - M5 Med/Low: 13 Currencies (icons + normals), 3 UI Panels (trade, tooltip, inventory + normals), 6 Status Effects (icons + normals), Loading screen + normal, 3 Login parallax layers + normals, 3 Agent Orb VFX + normals.
  - R&D Deliverables: `lod_generator.py`, `texture_compressor.py`, `viewport_culling_utils.py`, `mipmap_utils.py`, `RENDERING_OPTIMIZATION_TECH_REPORT.md` (327 lines), Metal instancing shader.
  - DRQ Coverage: 21 design requests in `docs/design_requests/inbox/` across 6 departments.
- **Verdict**: APPROVE
- **Unverified claims**: None. All claims independently verified via automated and custom test scripts.

## Attack Surface
- **Hypotheses tested**:
  - Tangent-space normal map validity (verified Sobel filtering and B-mean > 230 on all new normals; non-zero R/G variance confirms genuine surface detail).
  - Texture dimensions (100% 2^n on all new M3, M4, M5 assets).
  - Frame coordinate bounds (all frames within atlas dimensions, 0 out-of-bounds).
  - Unique pixel hashes (no placeholder copy-pasting across mobs, NPCs, currencies, status effects).
  - Code & doc hygiene (zero hard-cap violations across 615 scanned files).
- **Vulnerabilities found**:
  - Minor legacy observation: 10 legacy texture files in `assets/approved/` from 2026-09-29 / 2026-09-30 are non-PoT (e.g. 1280x256, 640x320, 1376x768). Does not affect new M3/M4/M5 deliverables, but logged as recommendation for future refactoring.
- **Untested angles**: Hardware-specific Apple Metal runtime profiling on physical iOS A17 device (simulated via mathematical model and unit tests).

## Key Decisions Made
- Executed all official verification scripts:
  - `verify_critical_assets.py` (96/96 checks pass)
  - `verify_m4_high_assets.py` (pass)
  - `verify_med_low_assets.py` (59/59 files pass)
- Executed full test suites:
  - `pytest tests/unit/test_m3_critical_assets.py` (96 pass)
  - `pytest tests/unit/test_m4_high_priority_assets.py` (47 pass)
  - `pytest tests/unit/test_med_low_priority_assets.py` (48 pass)
  - `pytest tests/unit/test_asset_pipeline_tools.py` (9 pass)
  - `pytest tests/unit/test_viewport_culling.py` (12 pass)
  - `pytest tests/e2e/test_asset_campaign_and_pipeline_e2e.py` (28 pass)
- Total tests passed: 240+ tests across unit and e2e suites with 0 failures.
- Formulated final verdict: APPROVE.
