Your Mission:
Perform an exhaustive forensic integrity audit across all code, assets, database, and test artifacts for the 30 Dark Fantasy Map Styles project:
1. Static Code Forensics:
   - Audit `client/webapp/js/engine/tile_map_renderer.js`, `client/webapp/js/engine/biome_texture_manager.js`, `server/world/map_style_catalog.py`, `server/world/map_biome_catalog.py`, `server/world/map_binary_serializer.py`.
   - Check for hardcoded test answers, mock facades, fake pass logic, bypassed verification, or cheated metrics.
2. Asset Forensics:
   - Audit `client/webapp/assets/map/styles/`: verify that textures and normal maps across all 30 biomes are authentic PNG binary image files (not 0-byte stubs, dummy strings, or placeholder text).
   - Verify tangent-space normal map channel integrity (Blue mean > 128).
3. Database Forensics:
   - Audit `data/map_styles.db`: verify authentic SQLite records (30 styles, 600 tile mappings, 90 props) with foreign key integrity, WAL mode, and real color palettes.
4. Test Suite Forensics:
   - Inspect tests in `tests/unit/test_map_styles_db.py`, `test_map_styles_catalog_sync.py`, `test_map_style_assets_integrity.py`, `test_30_biomes_generation_e2e.py`, `test_biome_texture_manager.js`.
   - Verify that tests make real, rigorous assertions and do NOT contain tautological `assert True`, bypassed checks, or disabled assertions.
5. Visual Artifact Forensics:
   - Audit captured screenshots (`biome_1_unobstructed.png`, `biome_2_unobstructed.png`, `biome_30_unobstructed.png`, `biome_3_independent_render.png`, `biome_10_independent_render.png`): verify they are real rendered gameplay canvas frames demonstrating authentic tile textures.
6. Deliverable:
   - Deliver a definitive, binary verdict: **CLEAN** or **INTEGRITY VIOLATION**.
   - Write full forensic evidence in `c:\Projects\FreeExile\.agents\teamwork\auditor_m4\handoff.md`.
   - Notify orchestrator via `send_message`.
