# BRIEFING — 2026-10-01T22:08:15Z

## Mission
Perform independent forensic integrity audit on Milestone M4 Iteration 2 deliverables (Fog of War, Minimap HUD, Anti-Maphack targeting, and Test Suite).

## 🔒 My Identity
- Archetype: forensic_auditor
- Roles: critic, specialist, auditor
- Working directory: c:\Projects\FreeExile\.agents\teamwork\auditor_m4_fix_1
- Original parent: 1cc48fc5-ce57-4f48-8964-24cab4bfcacc
- Target: Milestone M4 Iteration 2 (Fog of War & Minimap HUD)

## 🔒 Key Constraints
- Audit-only — do NOT modify implementation code
- Trust NOTHING — verify everything independently
- Zero lip-service; empirical verification with raw tool output
- Binary verdict: CLEAN or INTEGRITY VIOLATION

## Audit Scope
- **Work product**: Milestone M4 Iteration 2 deliverables (war_fog.js, war_fog_renderer.js, minimap_hud.js, monster_system.js, world_renderer.js, entity_renderer.js, index.html, test_fog_and_minimap.py)
- **Profile loaded**: General Project (Development Mode from ORIGINAL_REQUEST.md)
- **Audit type**: forensic integrity check

## Audit Progress
- **Phase**: reporting
- **Checks completed**:
  1. Static analysis & non-cheating checks (PASS)
  2. Code and hygiene line limit verifications (PASS)
  3. Anti-maphack targeting adversarial stress harness (10/10 PASS)
  4. Fog persistence dimension sanitization & flush tests (PASS)
  5. Absence of boolean tautologies in test_fog_and_minimap.py (PASS)
  6. Independent test execution (14/14 test_fog_and_minimap.py, 11/11 test_tile_collision.py, 81/81 test_poe2_map_system_e2e.py, 12/12 test_challenger_m4_empirical.py, 16/16 test_challenger_m4_2_minimap_stress.js, map_render_benchmark.js, 975/975 full unit test suite)
- **Checks remaining**: None
- **Findings so far**: CLEAN — No integrity violations or cheating detected.

## Key Decisions Made
- Confirmed that previous anti-maphack combat leak in `monster_system.js` and facade assertions in `test_fog_and_minimap.py` were genuinely remediated with empirical Node.js runtime tests.
- Issued binary verdict: CLEAN.

## Artifact Index
- handoff.md — Final forensic audit report
- DISPATCH.md — Assignment instructions
- progress.md — Liveness heartbeat

## Attack Surface
- **Hypotheses tested**:
  - Combat target acquisition leaks `window.monster` when in fog -> Refuted (returned null in all fog states)
  - Combat target acquisition leaks `window.monster` beyond maxRange -> Refuted (returned null when d > 7.5)
  - `war_fog.js` corrupts headers on negative/zero/non-numeric dimensions -> Refuted (strictly sanitized to 60x45)
  - `war_fog.js` loses pending debounced saves on sudden exit -> Refuted (beforeunload listener registered)
  - `test_fog_and_minimap.py` contains boolean tautologies or facade mocks -> Refuted (0 tautologies, real Node.js subprocess execution)
  - Deliverables violate line count caps -> Refuted (all 6 files within caps, zero hard cap hygiene errors)
- **Vulnerabilities found**: 0
- **Untested angles**: None within M4 scope

## Loaded Skills
- [none]
