# BRIEFING — 2026-10-01T01:01:30Z

## Mission
Forensic Integrity Audit of Milestone 3 Remediation changes (Milestone 3 Iteration 2).

## 🔒 My Identity
- Archetype: forensic_auditor
- Roles: critic, specialist, auditor
- Working directory: c:\Projects\FreeExile\.agents\teamwork\auditor_m3_r2_1
- Original parent: bc45a740-aa86-45b5-8706-381960281bc6
- Target: Milestone 3 Iteration 2 Remediation

## 🔒 Key Constraints
- Audit-only — do NOT modify implementation code
- Trust NOTHING — verify everything independently
- ORIGINAL_REQUEST.md takes precedence over dispatch contradictions
- Explicit forensic verdict: CLEAN or INTEGRITY VIOLATION

## Current Parent
- Conversation ID: bc45a740-aa86-45b5-8706-381960281bc6
- Updated: not yet

## Audit Scope
- **Work product**: Milestone 3 Remediation changes (`client/webapp/index.html`, `client/webapp/js/engine/entity_renderer.js`, `server/world/hideout_engine.py`, `tests/unit/test_hideout_engine.py`)
- **Profile loaded**: General Project
- **Audit type**: forensic integrity check

## Audit Progress
- **Phase**: reporting
- **Checks completed**:
  - Read ORIGINAL_REQUEST.md, PROJECT.md, and worker_m3_2 handoff.md
  - Git diff inspection across all 4 scoped files
  - No cheating / facade / dummy check
  - Canvas 2D decal rendering empirical check
  - ZoneEngine instance session eviction check
  - Test weakening and tampering check across unit, E2E, and security suites
  - Test suite execution: 21 unit tests PASS, 11 adversarial tests PASS, 50 E2E tests PASS, 9 webapp template tests PASS
  - Edge case stress-testing (positional/keyword ZoneEngine injection, error handling)
- **Checks remaining**: None
- **Findings so far**: CLEAN — 0 integrity violations detected

## Key Decisions Made
- Confirmed full behavioral authenticity of M3 remediation code changes.
- Formulated final verdict: CLEAN.

## Attack Surface
- **Hypotheses tested**:
  - Script tag suppression / bypassing in index.html (REFUTED: scripts are active, valid ES modules loaded before main.js)
  - Fake decal rendering (REFUTED: genuine Canvas 2D math, colors, pulsation, correct isometric layering)
  - Memory leak in active_instances / mock pass-throughs in hideout_engine.py (REFUTED: genuine .pop() from ZoneEngine and state clearance)
  - Unit or E2E test suite weakening (REFUTED: existing tests preserved, only new stricter assertions added)
- **Vulnerabilities found**: None in audited files.
- **Untested angles**: None within M3 remediation scope.

## Loaded Skills
None
