# BRIEFING — 2026-10-01T03:00:00Z

## Mission
Review Milestone 2 (Character Animation & Visceral Combat Feel Engine) implemented by worker_m2_1_gen3 and issue an independent, rigorous verdict.

## 🔒 My Identity
- Archetype: reviewer_critic
- Roles: reviewer, critic
- Working directory: c:\Projects\FreeExile\.agents\teamwork\reviewer_m2_1_gen3
- Original parent: 77cd448f-be37-473e-809c-59db9f78e386
- Milestone: Milestone 2 (Character Animation & Visceral Combat Feel Engine)
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Actively check for integrity violations (hardcoded test results, facade implementations, bypassed tasks, fabricated outputs)
- Run independent verification via pytest and lint tools
- Check line caps: <= 350 soft / <= 500 hard for logic, <= 700 for catalog
- Issue unambiguous verdict: APPROVE or REQUEST_CHANGES

## Review Scope
- **Files to review**:
  - `client/webapp/js/engine/animation_engine.js`
  - `client/webapp/js/data/weapon_swing_catalog.js`
  - `client/webapp/js/engine/canvas_renderer.js`
  - `client/webapp/js/engine/combat_feel_engine.js`
  - `client/webapp/js/engine/combat_skills.js`
  - `tests/unit/test_m2_animation_and_combat_feel.py`
  - `tests/e2e/test_poe2_ui_animation_vfx_e2e.py`
- **Interface contracts**: PROJECT.md, SCOPE.md, ORIGINAL_REQUEST.md
- **Review criteria**: Correctness, completeness, architecture, integrity, performance, line hygiene

## Key Decisions Made
- Executed independent test runs (`pytest tests/unit/test_m2_animation_and_combat_feel.py`, `pytest tests/e2e/test_poe2_ui_animation_vfx_e2e.py`, `python tools/lint/check_code_and_doc_hygiene.py --strict`).
- Verified zero integrity violations: no facades, no hardcoded bypasses, fully functional logic.
- Verified line limits strictly obeyed across all modified files.
- Completed adversarial review on edge cases (cancelWindup optional chaining, NaN safety, atlas frame bounds).
- Verdict: APPROVE.

## Artifact Index
- `handoff.md` — Final review and handoff report

## Review Checklist
- **Items reviewed**:
  - `animation_engine.js`: 5-phase kinetic machine (`idle`, `run`, `wind_up`, `impact`, `recovery`, `hit_stop`, `dodge`), 4 archetype clips, atlas aliasing, `cancelAction`.
  - `weapon_swing_catalog.js`: SLASH, THRUST, SLAM, BOLT data, styles, hit-stop configs.
  - `canvas_renderer.js`: updates and renders in game loop, camera shake offset integration.
  - `combat_feel_engine.js`: micro hit-stop freeze, 64-slot Ring Buffer, pop-in bounce scale, screen shake clamp.
  - `combat_skills.js`: animation cancelling on dodge roll, skill triggers.
- **Verdict**: APPROVE
- **Unverified claims**: None. All claims independently verified.

## Attack Surface
- **Hypotheses tested**:
  - Sprite atlas overflow when adding new weapon attack clips -> mitigated via `atlas_clip` aliasing.
  - `NaN` propagation in `hitStopTimer` -> mitigated in `combat_feel_engine.js` with defensive validation.
  - Action lock deadlock on dodge roll -> mitigated via `cancelAction` and lock resets.
- **Vulnerabilities found**: None critical; noted minor polish point regarding `WeaponSwingRenderer.cancelWindup`.
- **Untested angles**: Hardware GPU canvas benchmark under prolonged multi-hour stress (covered in M5).
