# Dispatch: Reviewer M5 2 (reviewer_m5_2)

**Target Role**: `teamwork_preview_reviewer`
**Working Directory**: `c:\Projects\FreeExile\.agents\teamwork\reviewer_m5_2`
**Authoritative User Request**: `c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md` (specifically section `## 2026-10-01T19:19:13Z` - R5)
**Worker Handoff**: `c:\Projects\FreeExile\.agents\teamwork\worker_m5_1\handoff.md`

## Mission
Adversarially challenge Milestone M5 for edge cases, performance, memory leaks, and anti-cheat/integrity guarantees:
1. Pathfinding Edge Cases:
   - Axial trajectories (`dx == 0` or `dy == 0`) in `hasLineOfSight`: verify no division by zero or NaN trap.
   - Closed rooms/unreachable targets: verify A* terminates gracefully without infinite loops or memory explosions.
   - Corner-cutting: verify diagonal movement never bypasses blocking corners.
2. Encounter Zone Edge Cases:
   - Rapid monster deaths: verify `zoneEncounterProgress` updates accurately without double-counting or negative values.
   - Safe Haven zones (`zone_player_hideout`, `zone_boundless_sanctuary`): 100% rejection of hostile spawns.
   - Waypoint safe radius (8.0 tiles): verify monsters immediately leash back when entering safe radius.
3. POI Wave Ambush Edge Cases:
   - Multiple rapid traversals over POI: verify ambush triggers exactly once.
   - Spawns near map edges or walls: verify all spawned minions land on passable tiles.
4. Line Limits & Code Hygiene:
   - `monster_system.js` <= 490 lines (Hard cap enforced by tests)
   - `grid_pathfinder.js` <= 320 lines
   - `monster_pack_system.js` <= 350 lines
   - `wilderness_zone_packs.js` <= 350 lines
   - `ambush_trigger_system.js` <= 300 lines
   - `boss_gate_controller.js` <= 200 lines
   - `world_renderer.js` <= 500 lines
   - `index.html` <= 200 lines
   - `test_encounter_zones.py` <= 300 lines
   - `python tools/lint/check_code_and_doc_hygiene.py --strict`

Execute and verify tests:
- `pytest tests/unit/test_encounter_zones.py -v`
- `pytest tests/unit/test_monster_poise_and_leash.py -v`
- `pytest tests/e2e/test_poe2_map_system_e2e.py -v`
- `node tools/perf/map_render_benchmark.js`
- `python tools/lint/check_code_and_doc_hygiene.py --strict`

Write `handoff.md` in your directory with an explicit verdict: `APPROVE` or `REQUEST_CHANGES`.
Send a message back to parent when complete.
