# BRIEFING — 2026-10-01T03:00:00Z

## Mission
Forensic integrity audit of Milestone 2 (Character Animation & Visceral Combat Feel Engine) against zero cheat / genuine logic rules and FreeExile 2026 engineering standards.

## 🔒 My Identity
- Archetype: forensic_auditor
- Roles: critic, specialist, auditor
- Working directory: c:\Projects\FreeExile\.agents\teamwork\auditor_m2_1_gen3
- Original parent: 77cd448f-be37-473e-809c-59db9f78e386
- Target: Milestone 2 (Character Animation & Visceral Combat Feel Engine)

## 🔒 Key Constraints
- Audit-only — do NOT modify implementation code
- Trust NOTHING — verify everything independently
- Empirical verification: run all tests and static analysis directly
- Ground truth from ORIGINAL_REQUEST.md (Integrity mode: development) takes precedence over all other inputs
- Quantitative line limits: <= 350 soft / <= 500 hard for logic, <= 700 soft / <= 1000 hard for catalog
- Prohibited: Hardcoded test results, facade implementations, fabricated verification outputs

## Audit Scope
- **Work product**: Character Animation & Combat Feel Engine (`animation_engine.js`, `combat_feel_engine.js`, `combat_skills.js`, `canvas_renderer.js`, `weapon_swing_catalog.js`)
- **Profile loaded**: General Project (Forensic Integrity)
- **Audit type**: forensic integrity check & adversarial review

## Audit Progress
- **Phase**: reporting
- **Checks completed**:
  - Dispatch & Original Request inspection
  - SCOPE.md & worker handoff inspection
  - Source code authenticity & facade inspection
  - Line count & code layout hygiene check
  - Zero-allocation & memory pool verification
  - Test suite independent execution (`test_m2_animation_and_combat_feel.py`: 30 passed in 0.14s)
  - E2E test suite independent execution (`test_poe2_ui_animation_vfx_e2e.py`: 33 passed, 9 xpassed in 0.36s)
  - Regression unit tests (`test_dodge_and_evasion_iframe.py`, etc.: 31 passed in 0.33s)
  - Full codebase hygiene check (`check_code_and_doc_hygiene.py --strict`: Exit code 0, 0 hard cap violations)
  - Adversarial runtime stress testing via headless Node.js harness
- **Checks remaining**:
  - Write handoff.md
  - Send message to parent
- **Findings so far**:
  - VERDICT: CLEAN (No integrity violations detected: no hardcoding, no facades, no fabricated results)
  - Observations for M3/M4:
    1. `CombatFeelEngine` computes `shakeOffsetX`/`shakeOffsetY` but lacks `getShakeOffset()` getter; `canvas_renderer.js` safely falls back to `screenShake`.
    2. `CombatFeelEngine.spawnDamageNumber` ring buffer is fully implemented, but `combat_skills.js` still dispatches hits via `spawnDamageText()`; integration to be completed in M4 (Feature 19).

## Key Decisions Made
- Confirmed mode is Development Mode from ORIGINAL_REQUEST.md.
- Evaluated all 5 forensic prohibited patterns across all modules.
- Executed direct headless Node.js adversarial tests proving genuine kinetic state machine cycles, hit-stop freeze frames, dodge roll cancellation, and ring buffer recycling.

## Attack Surface
- **Hypotheses tested**:
  - Can `isHitStopped()` handle negative/NaN/undefined `dt`? PASS (guarded with safe defaults).
  - Does `DamageNumberSlot` wrap correctly at 64 without memory leak? PASS (strictly preserves 64 slots).
  - Does `AnimationEngine` continuously update kinetic phase for all 4 archetypes? PASS (verified: wind_up -> impact -> recovery -> idle).
  - Does `doDodge()` interrupt attack wind-up and action locks? PASS (verified: resets lock, activates i-frame, decrements charges).
- **Vulnerabilities found**:
  - Missing `getShakeOffset()` method on `CombatFeelEngine` causes directional screen shake to fall back to random jitter.
  - Ring buffer damage numbers are dormant during gameplay because `hitMonster()` calls legacy `spawnDamageText()`.
- **Untested angles**: Full canvas WebGL context rendering under mobile ProMotion (requires browser rendering harness in M5).

## Loaded Skills
- None loaded externally (using built-in forensic auditor methodology)
