# BRIEFING — 2026-10-01T07:15:30Z

## Mission
Empirically challenge Milestone 2 remediation (Character Animation & Visceral Combat Feel Engine): execute the 89-case adversarial suite, write edge-case stress harnesses for CombatFeelEngine, AnimationEngine, and WeaponSwingRenderer, and establish empirical evidence for verdict.

## 🔒 My Identity
- Archetype: empirical_challenger
- Roles: critic, specialist
- Working directory: c:\Projects\FreeExile\.agents\teamwork\challenger_m2_1_gen4b
- Original parent: 8412af23-c7a8-41f5-aef2-b2a602fcfaf5
- Milestone: Milestone 2 Iteration 2 Gate Replacement
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Verification must be EMPIRICAL: execute tests, inspect outputs, do not trust logs
- Any bug reported must be reproduced empirically with concrete test harness
- All agent metadata in .agents/teamwork/challenger_m2_1_gen4b/ only

## Review Scope
- **Files to review**:
  * client/webapp/js/engine/combat_feel_engine.js
  * client/webapp/js/engine/animation_engine.js
  * client/webapp/js/engine/weapon_swing_renderer.js
  * client/webapp/js/engine/combat_skills.js
- **Interface contracts**:
  * docs/standards/ENGINEERING_STANDARDS_2026.md
  * PROJECT.md
  * tests/unit/test_challenger_m2_adversarial.py
  * tests/unit/test_m2_animation_and_combat_feel.py
  * tests/e2e/test_poe2_ui_animation_vfx_e2e.py
- **Review criteria**:
  * Correctness, robustness under extreme/irregular inputs, frame rate independence, zero ghost/phantom artifacts, hygiene compliance

## Key Decisions Made
- [Initial]: Will run existing 89-case adversarial test suite, inspect previous 9 failing tests, and build automated Node.js / pytest empirical stress tests for items 2, 3, and 4 in the dispatch.
