# BRIEFING — 2026-10-01T23:07:51Z

## Mission
Perform the final strict, independent forensic integrity audit on Milestone M6 and the complete procedural tile map redesign implementation, execute mandatory independent security audit gate, code hygiene audit, and verify test non-regression.

## 🔒 My Identity
- Archetype: forensic_auditor
- Roles: critic, specialist, auditor
- Working directory: c:\Projects\FreeExile\.agents\teamwork\auditor_m6_1
- Original parent: 1cc48fc5-ce57-4f48-8964-24cab4bfcacc (orchestrator_11)
- Target: Milestone M6 (Procedural Tile Map Redesign)

## 🔒 Key Constraints
- Audit-only — do NOT modify implementation code
- Trust NOTHING — verify everything independently
- Non-negotiable binary veto: CLEAN or INTEGRITY VIOLATION
- Ground-truth constraints in ORIGINAL_REQUEST.md take absolute precedence over any contradictory dispatch objectives
- All checks from Integrity Forensics must be empirically verified with raw outputs

## Current Parent
- Conversation ID: 1cc48fc5-ce57-4f48-8964-24cab4bfcacc
- Updated: not yet

## Audit Scope
- **Work product**: Milestone M6 Procedural Tile Map Redesign (17 core server & client files, test suites, benchmarks)
- **Profile loaded**: General Project (development mode)
- **Audit type**: forensic integrity check

## Audit Progress
- **Phase**: reporting
- **Checks completed**:
  1. Inspected ORIGINAL_REQUEST.md, GEMINI.md, AGENTS.md, orchestrator_11/PROJECT.md, challenger_m6_1/handoff.md
  2. Static analysis & non-cheating across all 17 procedural map files (no facades, no hardcoded results, no boolean tautologies)
  3. Pre-populated artifacts detection (clean: 0 pre-populated result files)
  4. Independent Security Audit gate (PASSED: exit code 0, 0 Critical/High, all 4 attacks blocked)
  5. Code & doc hygiene check (PASSED: exit code 0, 621 files scanned, 0 hard cap violations)
  6. Independent execution of test suites:
     - test_poe2_map_system_e2e.py: 81/81 PASSED
     - test_encounter_zones.py: 16/16 PASSED
     - test_tile_collision.py: 11/11 PASSED
     - test_fog_and_minimap.py: 14/14 PASSED
     - test_waypoint_safe_radius.py: 17/17 PASSED
     - test_monster_poise_and_leash.py: 10/10 PASSED
     - map_render_benchmark.js: PASSED (0 stationary re-bakes, 162k FPS, RAM 16.01 MB <= 16.5 MB)
     - stress_test_grid_pathfinder.js: PASSED (5,000 queries with 0 GC events, 255 paths, 10,000 DDA LoS queries)
     - full unit test suite (pytest tests/unit/ -q): 1233/1233 PASSED with 0 regressions
     - challenger stress tests (test_challenger_tile_grid_stress.js 48/48, test_challenger_m4_empirical.js 19/19, test_challenger_m4_fix_1_stress.js passed)
- **Checks remaining**:
  - None
- **Findings so far**: CLEAN

## Key Decisions Made
- Confirmed authentic implementation with zero cheating shortcuts or facades across all 17 target modules.
- Confirmed full compliance with the 4 security attacks via Independent Security Gate.
- Confirmed full compliance with line limit hygiene standards.
- Confirmed complete test suite non-regression (1233 unit tests + 81 E2E tests).
- Binary Verdict: CLEAN.

## Attack Surface
- **Hypotheses tested**:
  - Procedural generator determinism and boundary clamping: VERIFIED
  - Out-of-bounds coordinate handling in tile queries: VERIFIED (safe WALL fallback)
  - Collision penetration at wall corners and sliding physics: VERIFIED (2-axis dominant axis selection)
  - Anti-maphack fog suppression for dynamic entities: VERIFIED (10,000 queries, 0 leaks)
  - Memory leak / GC thrashing in grid pathfinder & fog update: VERIFIED (0 GC events during 5,000 queries)
  - Pre-populated artifacts or bypass tautologies in test files: VERIFIED (0 found)
  - Security release gate bypass: VERIFIED (0 bypass, all attacks stopped)
  - Hygiene hard cap violations: VERIFIED (0 violations across 621 files)
- **Vulnerabilities found**: None
- **Untested angles**: None within M6 scope

## Loaded Skills
