# BRIEFING — 2026-10-01T22:38:30Z

## Mission
Perform a strict, independent forensic integrity audit on Milestone M5 deliverables (Pathfinding, Monster Packs, Ambush Triggers, Boss Gates, Encounter Zones).

## 🔒 My Identity
- Archetype: forensic_auditor
- Roles: critic, specialist, auditor
- Working directory: c:\Projects\FreeExile\.agents\teamwork\auditor_m5_1
- Original parent: 1cc48fc5-ce57-4f48-8964-24cab4bfcacc
- Target: Milestone M5

## 🔒 Key Constraints
- Audit-only — do NOT modify implementation code
- Trust NOTHING — verify everything independently
- Provide evidence with raw tool output and diffs
- Block on ANY failure: binary verdict CLEAN or INTEGRITY VIOLATION
- Ground-truth constraints from ORIGINAL_REQUEST.md take precedence

## Audit Scope
- **Work product**: Milestone M5 deliverables
  - `client/webapp/js/engine/grid_pathfinder.js`
  - `client/webapp/js/data/wilderness_zone_packs.js`
  - `client/webapp/js/engine/monster_pack_system.js`
  - `client/webapp/js/engine/ambush_trigger_system.js`
  - `client/webapp/js/engine/monster_system.js`
  - `client/webapp/js/engine/boss_gate_controller.js`
  - `client/webapp/js/engine/world_renderer.js`
  - `client/webapp/index.html`
  - `tests/unit/test_encounter_zones.py`
- **Profile loaded**: General Project (Forensic Integrity)
- **Audit type**: forensic integrity check

## Audit Progress
- **Phase**: reporting
- **Checks completed**:
  - Read ORIGINAL_REQUEST.md, GEMINI.md, AGENTS.md, worker_m5_1/handoff.md
  - Line count & hygiene limits verification (All 9 files strictly within limits)
  - Static analysis & non-cheating verification (All authentic, zero-heap A*, real state machines)
  - Pre-populated artifact detection (Clean)
  - Independent test suite execution (1151 unit tests passed, 81 e2e map tests passed)
  - Performance benchmark (0 stationary re-bakes, <16.5MB RAM)
  - Adversarial review & stress-testing (Edge cases, division-by-zero, OOB, double-breach tested)
- **Checks remaining**: None
- **Findings so far**: CLEAN — No integrity violations detected.

## Attack Surface
- **Hypotheses tested**:
  - OOB start/goal in A* -> Handled safely (returns 0)
  - Trapped pathfinding across wall -> Navigates to closest reachable point without freezing
  - Division by zero / NaN in DDA raycaster -> Trajectories along axes handled with Infinity guards
  - Rapid double breach of boss gate -> Idempotent, second call rejected
  - Ambush trigger on dead player or safe haven -> Suppressed
- **Vulnerabilities found**: None
- **Untested angles**: None within M5 scope

## Loaded Skills
- None explicitly assigned in dispatch

## Key Decisions Made
- Confirmed mode: Development Mode (from ORIGINAL_REQUEST.md line 177)
- Confirmed zero cheating, zero facade implementations, zero hardcoded test result shortcuts
- Confirmed binary verdict: CLEAN

## Artifact Index
- DISPATCH.md — audit assignment
- BRIEFING.md — situational awareness
- progress.md — liveness heartbeat
- handoff.md — final audit report
