## Authoritative User Request
MANDATORY: Read the authoritative user request at:
c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md (specifically section ## 2026-10-01T19:19:13Z - R4).
Also read c:\Projects\FreeExile\GEMINI.md, c:\Projects\FreeExile\AGENTS.md, and c:\Projects\FreeExile\.agents\teamwork\worker_m4_1\handoff.md.

## Review Scope & Instructions
Independently review the code quality, contract adherence, and functional correctness of Milestone M4:
1. `client/webapp/js/ui/war_fog.js`
2. `client/webapp/js/ui/war_fog_renderer.js`
3. `client/webapp/js/ui/minimap_hud.js`
4. Entity suppression in `client/webapp/js/engine/world_renderer.js`, `entity_renderer.js`, `monster_system.js`
5. `client/webapp/index.html` DOM mounting and line count (<= 200 lines)
6. `tests/unit/test_fog_and_minimap.py`

Execute and verify all tests:
- `pytest tests/unit/test_fog_and_minimap.py -v`
- `pytest tests/unit/test_tile_collision.py -v`
- `pytest tests/unit/test_mobile_webapp_config.py -v`
- `pytest tests/e2e/test_poe2_map_system_e2e.py -v`
- `python tools/lint/check_code_and_doc_hygiene.py --strict`

Provide an explicit verdict: APPROVE or REQUEST_CHANGES in handoff.md and notify parent when complete.

Your Mission:
Perform an independent, objective and adversarial review of the Milestone 4 deliverables:
1. Examine `client/webapp/js/engine/tile_map_renderer.js` and `client/webapp/js/engine/biome_texture_manager.js`.
2. Verify:
   - Authentic tile texture pattern rendering via `CanvasPattern` / `drawImage`.
   - Chunk 16x16 OffscreenCanvas baking and caching: verify dirty flag mechanism and zero redundant re-bakes on static frames.
   - Renderer memory consumption: verify strict adherence to the <= 16.5 MB RAM ceiling ($8 \times 1024 \times 512 \times 4$ + compact grid).
   - Graceful procedural fallback when texture loading is pending or fails.
   - Code length constraints: verify compliance with <= 350 lines soft cap.
3. Review `worker_m4_qa\handoff.md` and test metrics (379/379 pytest, 8/8 node tests, 66.15 FPS).
4. Deliver your structured verdict (APPROVE or REQUEST_CHANGES) with clear evidence in `c:\Projects\FreeExile\.agents\teamwork\reviewer_m4_1\handoff.md`.
5. Notify orchestrator via `send_message`.
