- Remediation handoff to review: c:\Projects\FreeExile\.agents\teamwork\worker_m2_2_gen3\handoff.md
- Relevant source files:
  * c:\Projects\FreeExile\client\webapp\js\engine\combat_feel_engine.js
  * c:\Projects\FreeExile\client\webapp\js\engine\weapon_swing_renderer.js
  * c:\Projects\FreeExile\client\webapp\js\engine\animation_engine.js

  * c:\Projects\FreeExile\tests\unit\test_challenger_m2_adversarial.py

Your Mission:
Objectively and critically review the Milestone 2 remediation performed by worker_m2_2_gen3.
Focus areas:
1. Interface Conformance & Cross-Module Contracts:
   - Verify `WeaponSwingRenderer.cancelWindup()` contract with `combat_skills.js:283`.
   - Verify `CombatFeelEngine.getShakeOffset()` contract with `canvas_renderer.js:276`.
   - Verify `CombatFeelEngine.isHitStopped(dt)` vs `update(dt)` timer decay interaction.
2. Kinetic State Machine Robustness:
   - Check edge cases in `animation_engine.js`: frame loop handling, action lock release, callbacks, facing directions.
   - Verify no phantom swings after dodge roll.
3. Code Hygiene:
   - Ensure all files comply with line limits (<= 350 soft cap / <= 500 hard cap).
4. Run tests:
   - `pytest tests/unit/test_m2_animation_and_combat_feel.py -v`
   - `pytest tests/unit/test_challenger_m2_adversarial.py -v`
   - `pytest tests/e2e/test_poe2_ui_animation_vfx_e2e.py -v`

Deliverable:
Write a comprehensive `handoff.md` in `c:\Projects\FreeExile\.agents\teamwork\reviewer_m2_2_gen4b\handoff.md` with:
- Observation (verified facts, file lines, test outputs)
- Logic Chain
- Caveats
- Conclusion with explicit verdict: **APPROVE** or **REQUEST_CHANGES**
- Verification commands and results
Send a concise completion message back to parent when done.
