## Executive Summary & Verdict
### **VERDICT: APPROVE**
Following the `REQUEST_CHANGES` verdict in Iteration 1 (which identified disconnected client modules in `index.html`, missing call sites for `renderLeaderAuraDecal`, and active instance session leaks upon portal depletion), `worker_m3_2` has implemented a complete, architecturally sound, and clean remediation:
1. **Client Runtime Wiring**: `client/webapp/index.html` (line 183) now properly imports `js/data/wilderness_zone_packs.js`, `js/engine/monster_pack_system.js`, and `js/engine/ambush_trigger_system.js` as ES modules. File line count remains strictly compliant at 199 lines (Soft Cap $\le 200$, Hard Cap $\le 400$).
2. **Pack Leader Visual Aura Decal**: `client/webapp/js/engine/entity_renderer.js` (lines 125–128) now invokes `window.renderLeaderAuraDecal(ctx, m, mPos.x, mPos.y, ...)` beneath the animated entity sprite and atop the soft shadow, displaying color-coded pulsating aura rings in the 2.5D isometric viewport.
3. **Hideout Instance Session Cleanup & Isolation**: `server/world/hideout_engine.py` (lines 273–279) clears `dev.active_map = None`, `dev.active_instance_id = None`, and purges the instance from `zone_engine.active_instances` upon the 6th portal consumption. Additionally, `create_map_instance_session` (lines 285–326) provides genuine multi-tenant `InstanceSession` registration with isolated `SpatialGrid(cell_size=64.0)`.
4. **Integrity Audit**: PASS. No hardcoded test responses, no facade/dummy stubs, no task bypasses, and no self-certifying shortcuts were detected.
5. **Test & Hygiene Gates**: All 21 scoped unit tests pass (100%), all 11 adversarial fuzzing tests pass (100%), all 9 webapp dynamic template tests pass (100%), 47 E2E tests pass (1 xfail, 2 xpass), strict hygiene check reports 0 Hard Cap violations, and the Game Design Matrix is 100% in sync.

## 1. Observation
Direct examination and execution results across the codebase:
### 1.1. Server Map Device Portal Consumption & Session Lifecycle
In `server/world/hideout_engine.py` (lines 222–284):
```python
def enter_map_portal(
self,
player_id: str,
portal_index: Optional[int] = None,
zone_engine: Optional[Any] = None,
) -> Tuple[bool, str, Optional[Dict[str, Any]]]:
...
if portal_index is not None and not isinstance(portal_index, int) and zone_engine is None:
zone_engine = portal_index
portal_index = None
...
# If exhausted all 6 portals, close device and purge instance session from ZoneEngine
if dev.portals_remaining == 0:
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
msg = f"Đã bước qua cổng #{target_idx + 1}. Đây là CỔNG CUỐI CÙNG (0/6)! Tinh Đồ Nghi đã khép lại."
```
- Line 470 total lines (strictly within Hard Cap $\le 500$).
- Parameter handling accommodates both positional and keyword invocations (`enter_map_portal(player_id, zone_engine=ze)` and `enter_map_portal(player_id, ze)`).
- When `dev.portals_remaining == 0`, `dev.active_map` and `dev.active_instance_id` are reset to `None`, and the instance is popped from `zone_engine.active_instances` safely using `hasattr` and `pop(..., None)`.
### 1.2. Map Instance Session Creation & Spatial Grid Isolation
In `server/world/hideout_engine.py` (lines 285–326):
```python
def create_map_instance_session(
self,
player_id: str,
astral_map: AstralMap,
zone_engine: Optional[Any] = None,
) -> Tuple[bool, str, Dict[str, Any]]:
...
if zone_engine is not None and hasattr(zone_engine, "active_instances"):
from server.world.spatial_grid import SpatialGrid
from server.world.zone_types import InstanceSession
session = InstanceSession(
instance_id=dev.active_instance_id or f"inst_map_{astral_map.map_id}",
template_id=astral_map.map_id,
instance_zone_id=astral_map.zone_template_id,
leader_player_id=player_id,
member_player_ids=[],
current_layer=1,
max_layers=1,
lives_remaining=6,
time_limit_sec=7200,
start_timestamp_ms=int(time.time() * 1000),
spatial_grid=SpatialGrid(cell_size=64.0),
)
zone_engine.active_instances[session.instance_id] = session
```
- Each session receives an isolated `SpatialGrid(cell_size=64.0)`.
- Verified multi-session isolation with 20 concurrent sessions; entity injection into session 0 does not leak into sessions 1..19 or the safe haven spatial grid.
### 1.3. Unit Test Verification for Portal Exhaustion
In `tests/unit/test_hideout_engine.py` (lines 194–231):
```python
def test_map_device_portal_exhaustion_cleans_zone_engine_session(engine: HideoutEngine) -> None:
from server.world.zone_engine import ZoneEngine
ze = ZoneEngine()
player_id = "hero_swordsman_01"
astral_map = AstralMap(
map_id="map_t14_blood_scale",
name="Vòng Xoáy U Minh Cổ Địa",
tier=14,
zone_template_id="zone_blood_scale_ruins"
)
ok, _, res = engine.create_map_instance_session(player_id, astral_map, zone_engine=ze)
inst_id = res["instance_id"]
assert inst_id in ze.active_instances
...
ok_final, msg_final, res_final = engine.enter_map_portal(player_id, zone_engine=ze)
assert res_final["portals_remaining"] == 0
assert inst_id not in ze.active_instances
dev = engine.get_or_create_hideout(player_id).map_device
assert dev.active_instance_id is None
assert dev.active_map is None
```
- File line count: exactly 231 lines (Soft Cap $\le 350$, Hard Cap $\le 500$).
### 1.4. Client WebApp Module Integration
In `client/webapp/index.html` (lines 182–185):
```html
182:
183:
184:
185:
```
- Total lines: exactly 199 lines (Soft Cap $\le 200$, Hard Cap $\le 400$).
- All 3 previously orphaned modules are now loaded as ES modules.
### 1.5. Pack Leader Aura Rendering Hook
In `client/webapp/js/engine/entity_renderer.js` (lines 125–128):
```javascript
125: // Leader Aura Ground Decal (PoE2 Pack Leader Visual Aura Indicator)
126: if (m.isPackLeader && typeof window.renderLeaderAuraDecal === 'function') {
127: window.renderLeaderAuraDecal(ctx, m, mPos.x, mPos.y, (window.gameTimeSec || performance.now() * 0.001));
128: }
```
- Render order: monster soft shadow (lines 120–123) $\rightarrow$ leader aura ground decal (lines 125–128) $\rightarrow$ animated sprite / frame (lines 130–148) $\rightarrow$ red blood hit flash $\rightarrow$ HP bar and nameplate.
- Total lines: 422 lines (strictly within Hard Cap $\le 500$).

## 2. Logic Chain
1. **Observation 1.1 $\rightarrow$ Elimination of Session Leaks**: By passing `zone_engine` into `enter_map_portal` and calling `zone_engine.active_instances.pop(dev.active_instance_id, None)` when `dev.portals_remaining == 0`, server memory no longer accumulates stale `InstanceSession` objects or spatial grids across repeated endgame map runs.
2. **Observation 1.1 $\rightarrow$ Map Device Sealing Invariant**: Resetting both `dev.active_map = None` and `dev.active_instance_id = None` guarantees that subsequent `enter_map_portal` requests are immediately rejected with `"Thiên Đạo Tinh Đồ Nghi hiện không có Cổng nào mở hoặc đã hết lượt vào (0/6)!"`, satisfying PoE2 portal depletion mechanics.
3. **Observation 1.2 $\rightarrow$ Multi-Tenant Security & Spatial Isolation**: Constructing a distinct `SpatialGrid(cell_size=64.0)` per instance prevents cross-instance entity leakage and protects safe haven grids from hostile monster contamination.
4. **Observation 1.4 $\rightarrow$ Real Browser Integration**: Adding `
