## Forensic Audit Summary

| Check Item | Requirement / Concern | Audit Result | Status |
|---|---|---|:---:|
| **Check 1: Client Script Integration** | Are script tags in `client/webapp/index.html` genuine, active, correctly ordered, and not bypassed/commented out? | Verified active `<script type="module">` tags loading `wilderness_zone_packs.js`, `monster_pack_system.js`, `ambush_trigger_system.js` at line 183. | **PASS** |
| **Check 2: Canvas Decal Rendering** | Is `renderLeaderAuraDecal` in `entity_renderer.js` genuinely rendering ground decals on canvas? | Verified dynamic Canvas 2D ellipse stroke/fill, trigonometric pulse, color mapping by aura type, and correct isometric Z-layering below entity sprite. | **PASS** |
| **Check 3: Map Session Lifecycle Cleanup** | Does `hideout_engine.py` genuinely purge instances from `active_instances` upon 6th portal consumption without dummy pass-throughs? | Verified `.pop(dev.active_instance_id, None)` from `ZoneEngine.active_instances`, clearing `dev.active_map = None` and `dev.active_instance_id = None`. | **PASS** |
| **Check 4: Test Suite Integrity** | Were any unit, security, or E2E tests weakened or modified to artificially pass? | Zero test weakening. `git diff` shows existing assertions preserved; stricter assertions and 1 new comprehensive unregistration test added. E2E and adversarial test files had zero edits. | **PASS** |
| **Check 5: Code Hygiene & Line Caps** | Do modified files respect FreeExile length caps? | `index.html` (199 lines <= 200 soft cap), `entity_renderer.js` (423 lines <= 500 hard cap), `hideout_engine.py` (471 lines <= 500 hard cap), `test_hideout_engine.py` (231 lines <= 350 soft cap). | **PASS** |

## 1. Observation

### 1.1. Git Diff Inspection of Scoped Files
Direct inspection via `git diff HEAD -- ...` confirms changes are confined to the intended remediation scope:

1. **`client/webapp/index.html`**:
   - Line 183: Active `<script type="module">` tags added:
     ```html
     <script type="module" src="js/data/wilderness_zone_packs.js"></script><script type="module" src="js/engine/monster_pack_system.js"></script><script type="module" src="js/engine/ambush_trigger_system.js"></script>
     ```
   - Total file length: 199 lines (Soft Cap <= 200 lines, Hard Cap <= 400 lines).
   - Placement: Positioned before `world_renderer.js`, `vfx_renderer.js`, `entity_renderer.js`, and `main.js`.
   - Node.js syntax/module check: Successfully imported all 3 ES modules and exported functions (`populateZonePacks`, `renderLeaderAuraDecal`, `updateMonsterPackAI`, `updateAmbushTriggers`).

2. **`client/webapp/js/engine/entity_renderer.js`**:
   - Lines 125–128: Leader aura decal rendering hook inserted inside `renderEntities()` loop:
     ```javascript
     // Leader Aura Ground Decal (PoE2 Pack Leader Visual Aura Indicator)
     if (m.isPackLeader && typeof window.renderLeaderAuraDecal === 'function') {
       window.renderLeaderAuraDecal(ctx, m, mPos.x, mPos.y, (window.gameTimeSec || performance.now() * 0.001));
     }
     ```
   - Position: Placed immediately after monster soft shadow (`ctx.ellipse(mPos.x, mPos.y + 4, shadowRx, shadowRy, ...)`) and before animated sprite drawing (`AnimationEngine.drawEntityFrame`).
   - Total file length: 423 lines (Hard Cap <= 500 lines). `node -c` confirms zero syntax errors.

3. **`server/world/hideout_engine.py`**:
   - Lines 222–283: `enter_map_portal` updated with `zone_engine: Optional[Any] = None` and polymorphic argument normalization:
     ```python
     if portal_index is not None and not isinstance(portal_index, int) and zone_engine is None:
         zone_engine = portal_index
         portal_index = None
     ```
   - Lines 273–279: When `dev.portals_remaining == 0`:
     ```python
     if zone_engine is not None and hasattr(zone_engine, "active_instances"):
         if dev.active_instance_id and dev.active_instance_id in zone_engine.active_instances:
             zone_engine.active_instances.pop(dev.active_instance_id, None)
     dev.active_map = None
     dev.active_instance_id = None
     ```
   - Lines 285–326: `create_map_instance_session` added, activating map device and registering full `InstanceSession` with isolated `SpatialGrid(cell_size=64.0)` into `zone_engine.active_instances`.
   - Total file length: 471 lines (Hard Cap <= 500 lines).

4. **`tests/unit/test_hideout_engine.py`**:
   - Lines 120–124: Added post-exhaustion assertions in `test_map_portal_consumption_lifecycle` (`assert hideout.map_device.active_map is None`, `assert hideout.map_device.active_instance_id is None`, `assert hideout.map_device.portals_remaining == 0`).
   - Lines 193–231: Added `test_map_device_portal_exhaustion_cleans_zone_engine_session`, creating a map instance with `ZoneEngine`, traversing 5 portals, and verifying `inst_id not in ze.active_instances` after the 6th portal.
   - Total file length: 231 lines (Soft Cap <= 350 lines).

5. **Untouched Test Suites**:
   - `git diff HEAD -- tests/e2e/` returned 0 lines (clean).
   - `git diff HEAD -- tests/security_fuzzing/` returned 0 lines (clean).

### 1.2. Independent Test Execution Results
All test suites were executed independently:
- **Milestone 3 Unit Tests**:
  `pytest tests/unit/test_monster_pack_and_affixes.py tests/unit/test_wilderness_encounter_density.py tests/unit/test_ambush_trigger_engine.py tests/unit/test_hideout_engine.py -v`
  -> **21 passed in 0.35s** (100% PASS).
- **Adversarial Security Fuzzing Suite**:
  `pytest tests/security_fuzzing/test_wilderness_encounters_adversarial.py -v`
  -> **11 passed in 0.28s** (100% PASS).
- **E2E Zone & Encounter Test Suite**:
  `pytest tests/e2e/test_poe2_zone_and_encounter_e2e.py -v`
  -> **47 passed, 1 xfailed (baseline), 2 xpassed in 0.38s**.
- **WebApp Dynamic Templates Suite**:
  `pytest tests/unit/test_webapp_dynamic_templates.py -v`
  -> **9 passed in 0.92s** (100% PASS).
- **Game Design Matrix Verification**:
  `python tools/lint/verify_game_design_matrix.py`
  -> **Status: PASS, 100% IN SYNC**.
- **Adversarial Edge Case Stress Script**:
  Empirical run with polymorphic argument passing (`enter_map_portal(pid, ze)` positional vs keyword) and invalid map tiers -> **100% PASS**.

## 2. Logic Chain

1. **Script Integration Validity**: By inspecting `client/webapp/index.html` directly, the scripts are found at line 183 inside the active script execution block. Because `monster_system.js` uses defensive feature detection (`if (typeof window.getWildernessZoneMonsters === 'function')`), importing these 3 ES modules directly bridges the runtime gap, allowing wilderness zones to spawn genuine pack structures and ambush triggers rather than falling back to dummy tables.
2. **Decal Rendering Authenticity**: Inspection of `monster_pack_system.js:renderLeaderAuraDecal` shows non-trivial Canvas 2D math (variable radii based on `Math.sin`, color branching across 5 aura types, opacity modulation, and dual-ellipse inner fill + outer stroke). Its call site in `entity_renderer.js:126` is positioned between the ground shadow and the sprite frame, respecting isometric rendering order.
3. **Session Purge Authenticity**: In `hideout_engine.py:273-279`, the eviction logic directly accesses `zone_engine.active_instances.pop(dev.active_instance_id, None)` upon reaching `portals_remaining == 0`. It resets both `active_map` and `active_instance_id` to `None`. The adversarial test `test_wilderness_encounters_adversarial.py::TestSessionIsolationAndSpatialGridStress::test_multi_session_concurrency_and_grid_isolation_20_sessions` directly instantiates 20 instances via `create_map_instance_session` and verifies complete isolation. No mock or dummy pass-through is used.
4. **Absence of Test Tampering**: Comparing git diffs against HEAD confirmed that no existing unit, adversarial, or E2E tests were loosened. In fact, `test_hideout_engine.py` added stricter state checks, and the adversarial suite passed with zero modifications.
5. **Deductive Conclusion**: Since all empirical checks passed without evidence of facade implementations, hardcoded test strings, or test weakening, the work product is authentic and compliant with PoE2 architecture.

## 3. Caveats

- **Full Suite Pre-existing Failures**: In the repository-wide unit suite (`pytest tests/unit/`), two unrelated tests (`test_fog_integrity_and_anti_exploit.py` and `test_war_fog_and_procedural_map.py`) fail due to ongoing war fog / procedural map refactoring by other sub-agents. These are outside the Milestone 3 remediation scope.
- **Hygiene Gate Warning on Agent Scratch Files**: Running `check_code_and_doc_hygiene.py --strict` flags `.agents\teamwork\reviewer_m1_2\adversarial_tests.py` (581 lines) which is an internal agent file in another agent's directory, but all project code and tests in scope are strictly within caps.

---

## 4. Conclusion

The Milestone 3 Remediation work product is authentic, correct, and rigorously tested.
- No facade or dummy implementations were found.
- Script tags are properly placed in `index.html` and execute correctly.
- Ground aura decals render genuine Canvas 2D visuals with proper isometric layering.
- Map device portal consumption cleanly purges sessions from `ZoneEngine.active_instances` upon exhaustion.
- No test suites were weakened or bypassed.

**Final Forensic Verdict**: **CLEAN**
