# BRIEFING — 2026-10-01T09:22:00Z

## Mission
Independent Post-Victory Audit for FreeExile WebApp animation bug fixes: R1 (atlas frame mapping & pivot), R2 (turn inertia snap freeze & run-to-idle transition), R3 (debug overlay hidden by default), and line caps / hygiene.

## 🔒 My Identity
- Archetype: victory_auditor
- Roles: critic, specialist, auditor, victory_verifier
- Working directory: c:/Projects/FreeExile/.agents/teamwork/teamwork_preview_victory_auditor_1/
- Original parent: 019c2237-8a5c-4adf-85e2-4f62dfa98cd6
- Target: full project (animation engine bug fixes)

## 🔒 Key Constraints
- Audit-only — do NOT modify implementation code
- Trust NOTHING — verify everything independently
- Zero shared context with implementation team
- A single failure in forensic / independent execution = VICTORY REJECTED

## Current Parent
- Conversation ID: 019c2237-8a5c-4adf-85e2-4f62dfa98cd6
- Updated: 2026-10-01T09:22:00Z

## Audit Scope
- **Work product**: client/webapp/js/engine/animation_engine.js, client/webapp/js/engine/canvas_renderer.js, tests/unit/test_animation_frame_mapping_and_inertia.py
- **Profile loaded**: General Project (Victory Audit & Integrity Forensics)
- **Audit type**: victory audit

## Audit Progress
- **Phase**: reporting
- **Checks completed**:
  - Phase A: Timeline & provenance check passed (iterative review cycle R1-R3, git working tree clean and authentic).
  - Phase B: Integrity & anti-cheating forensics passed (zero hardcoded test strings, genuine atlas grid modulo and cycle-safe graph math, no pre-populated logs).
  - Phase C: Independent test execution passed:
    - `pytest tests/unit/test_animation_frame_mapping_and_inertia.py -v`: 46/46 PASSED.
    - Regression suites (animation pipeline, combat feel, character vfx, E2E): 78 passed, 9 xpassed.
    - Node empirical harness: 5/5 PASSED.
    - Node adversarial security harness: 4/4 PASSED.
    - Independent Node script (914 assertions across all 6 classes, clips, pivots, snap freeze, click-to-move, debug overlay): 914/914 PASSED.
    - Live Edge headless browser test: 0 errors.
    - Hygiene: strict check passed, `animation_engine.js` is 348 lines (<= 350 lines).
- **Checks remaining**: None.
- **Findings so far**: CLEAN — VICTORY CONFIRMED.

## Attack Surface
- **Hypotheses tested**:
  - Aliased attack clips skew subsequent animations (disproven: aliased clips are skipped in frame counter and map to correct target row).
  - Residual turn inertia continues lerping when velocity is 0 (disproven: lerp is strictly gated on actualVel >= 0.05 and facingDir).
  - Non-finite or negative pivots poison canvas transform matrix (disproven: Number.isFinite guards and fallback logic protect all paths).
  - Circular alias graphs cause infinite loops (disproven: visited Set breaks immediately).
  - Debug overlay active by default (disproven: window.__DEBUG_ANIM__ initializes to false).
- **Vulnerabilities found**: None.
- **Untested angles**: Physical device pixel ratio rendering on mobile hardware (non-critical visual subpixel rasterization note).

## Loaded Skills
None loaded.

## Key Decisions Made
- All acceptance criteria independently re-executed and verified empirically. Verdict: VICTORY CONFIRMED.
