# BRIEFING — 2026-10-01T09:30:00Z

## Mission
Independently audit and verify the victory claim for FreeExile animation fixes (atlas frame mapping, turn-inertia lerp snap freeze, debug overlay) with zero shared assumptions.

## 🔒 My Identity
- Archetype: victory_auditor
- Roles: critic, specialist, auditor, victory_verifier
- Working directory: c:/Projects/FreeExile/.agents/teamwork/sentinel_victory_auditor_1/
- Original parent: 78e67afc-153b-4ea0-b7d4-885680ebcd4c
- Target: FreeExile animation fixes (atlas frame mapping, turn-inertia lerp snap freeze, debug overlay)

## 🔒 Key Constraints
- Audit-only — do NOT modify implementation code
- Trust NOTHING — verify everything independently
- Zero shared assumptions with orchestrator / implementation team
- Re-run all tests independently from clean execution
- Enforce line limit <= 350 on animation_engine.js
- Verify debug overlay is hidden by default

## Audit Scope
- **Work product**: `client/webapp/js/engine/animation_engine.js`, `client/webapp/js/engine/canvas_renderer.js`, tests in `tests/unit/test_animation_frame_mapping_and_inertia.py`
- **Profile loaded**: General Project / Victory Audit
- **Audit type**: victory audit (Phases A, B, C)
- **Integrity mode**: development (from ORIGINAL_REQUEST.md)

## Audit Progress
- **Phase**: reporting
- **Checks completed**:
  - Dispatch received and recorded in DISPATCH.md
  - Phase A: Timeline & Provenance Audit (PASS)
  - Phase B: Integrity & Anti-Cheating Forensics (PASS)
  - Phase C: Independent Test Execution & Acceptance Verification (PASS)
- **Checks remaining**: None
- **Findings so far**: CLEAN — VICTORY CONFIRMED

## Attack Surface
- **Hypotheses tested**:
  - Aliased clips (`atlas_clip: 'attack_slash'`) skewing subsequent clips: verified mathematically and empirically that non-aliased row calculation is preserved.
  - Pivot calculation from frameObj/clip/manifest: verified with custom array and object pivots.
  - Stationary turn-inertia freeze: verified that smoothAngle remains constant across 60 stationary frames.
  - Run -> idle transition latency: verified transition occurs in <= 1 frame when actualVel < 0.05.
  - Negative and out-of-bounds frameIndex: verified modulo wrapping.
  - Non-finite numbers (NaN, Infinity): verified fallbacks without throwing.
  - Circular alias references: verified visited Set breaks cycle and returns false.
  - Debug overlay visibility: verified defaults to false, toggleable via keydown/query param.
  - DevTools console errors: verified 0 errors in headless browser.
  - Line count limits: verified animation_engine.js is 348 lines (<= 350).
- **Vulnerabilities found**: None.
- **Untested angles**: None.

## Loaded Skills
- Standard victory auditor & forensic profile loaded.

## Key Decisions Made
- All tests and verification scripts executed independently via CLI and headless browser.
- Verdict reached: VICTORY CONFIRMED.
