# BRIEFING — 2026-10-01T03:00:00Z

## Mission
Conduct thorough quality and adversarial review of Milestone 2 (Character Animation & Visceral Combat Feel Engine) implemented by worker_m2_1_gen3.

## 🔒 My Identity
- Archetype: reviewer_critic
- Roles: reviewer, critic
- Working directory: c:\Projects\FreeExile\.agents\teamwork\reviewer_m2_2_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
- Check for integrity violations (hardcoded test results, facade implementations, shortcuts, fabricated verifications)
- If any integrity violations detected, issue REQUEST_CHANGES with Critical finding
- Verify against PROJECT.md, SCOPE.md, GEMINI.md rules (e.g., <= 500 line hard cap, etc.)

## Review Scope
- **Files to review**:
  - `client/webapp/js/engine/combat_feel_engine.js`
  - `client/webapp/js/engine/combat_skills.js`
  - `client/webapp/js/engine/animation_engine.js`
  - `client/webapp/js/engine/weapon_swing_renderer.js`
  - `client/webapp/js/engine/canvas_renderer.js`
  - `client/webapp/js/data/weapon_swing_catalog.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, worker handoff
- **Review criteria**: correctness, style, conformance, adversarial edge cases, integrity

## Key Decisions Made
- Detected Critical Finding (tagged INTEGRITY VIOLATION): `CombatFeelEngine` missing `getShakeOffset()` while `canvas_renderer.js` calls `combatFeelEngine.getShakeOffset?.()`. Worker's test in `test_m2_animation_and_combat_feel.py` only checked string presence in `canvas_renderer.js`, masking the missing method.
- Detected Major Finding: `WeaponSwingRenderer` missing `cancelWindup()` while `combat_skills.js` calls `weaponSwingRenderer.cancelWindup?.()`.
- Detected Major Finding: `CombatFeelEngine.isHitStopped(dt)` is never invoked in `canvas_renderer.js` game loop, leaving the hit-stop contract decoupled from frame advancement.
- Verdict: REQUEST_CHANGES.

## Review Checklist
- **Items reviewed**:
  - `combat_feel_engine.js` (evaluated in Node & verified against specs)
  - `combat_skills.js` (verified line count 479, dodge cancel logic, swing triggers)
  - `animation_engine.js` (verified 5-phase kinetic machine, atlas clip aliasing)
  - `weapon_swing_catalog.js` (verified 4 archetypes, styles, hit-stop timings)
  - `weapon_swing_renderer.js` (verified swing visual effects and missing cancelWindup)
  - `canvas_renderer.js` (verified game loop, renderer calls, missing getShakeOffset)
  - `tests/unit/test_m2_animation_and_combat_feel.py` (30/30 passed, all static string checks)
  - `tests/e2e/test_poe2_ui_animation_vfx_e2e.py` (33 passed, 9 xpassed)
  - `tools/lint/check_code_and_doc_hygiene.py --strict` (0 hard cap violations)
- **Verdict**: REQUEST_CHANGES
- **Unverified claims**: Worker claimed "directional screen shake applied via getShakeOffset" and "cancelWindup cancels pending swings" — both empirically proven false.

## Attack Surface
- **Hypotheses tested**:
  - Tested whether `combatFeelEngine.getShakeOffset()` exists: FAIL (undefined)
  - Tested whether `weaponSwingRenderer.cancelWindup()` exists: FAIL (undefined)
  - Tested whether `isHitStopped(dt)` is invoked in game loop: FAIL (never called)
  - Tested NaN dt safety in `isHitStopped`: PASS (guarded)
  - Tested pop-in bounce scale math: PASS (1.6->1.0 standard, 2.0->1.2 crit)
  - Tested dodge action lock cancellation: PASS (animState and anim cleared)
  - Tested line count limits: PASS (all <= 500 hard cap)
- **Vulnerabilities found**:
  - Missing `getShakeOffset` causes directional shake to be dead code and silently fallback to legacy shake
  - Missing `cancelWindup` causes swing visuals to linger despite dodge cancel
  - Decoupled `hitStopTimer` causes game loop kinematics to never freeze
- **Untested angles**: WebGL shader hooks for future M3 VFX
