## Status: COMPLETED

### Completed
- [x] Initialized workspace and reviewed dispatch requirements, original request, and asset survey.
- [x] Created BRIEFING.md and DISPATCH.md tracking.
- [x] Inspected existing asset generators and tools in `tools/asset_pipeline/`.
- [x] Implemented modular generator scripts:
  * `tools/asset_pipeline/m4_passive_tree_generator.py` (64x64, 128x128, 128x32, 1024x1024)
  * `tools/asset_pipeline/m4_tileset_generator.py` (4 walls 128x128, 4 floors 128x64, 2 arena floors 256x128)
  * `tools/asset_pipeline/m4_npc_generator.py` (5 NPCs: avatar 128x128, portrait 256x256, standee 256x512, standee_normal 256x512)
  * `tools/asset_pipeline/m4_normal_utils.py` (Vectorized Sobel tangent-space filter with B-mean > 128 guarantee)
- [x] Generated all 46 assets into their designated locations:
  * `client/webapp/assets/ui/passive_tree/` (6 assets)
  * `client/webapp/assets/map/` (20 assets)
  * `client/webapp/assets/characters/` & `characters/npcs/` (20 assets)
- [x] Verified 100% Power-of-Two dimensions, normal maps B mean > 128.0 (241.3 to 253.4), and file size budgets (all map tiles <= 6.11KB << 50KB, UI icons <= 4.22KB << 150KB).
- [x] Created and executed verification script `tools/asset_pipeline/verify_m4_high_assets.py` (All checks passed).
- [x] Created and executed Pytest test suite `tests/unit/test_m4_high_priority_assets.py` (47/47 passed).
- [x] Verified zero regressions with `tests/e2e/test_asset_campaign_and_pipeline_e2e.py` (28/28 passed).
- [x] Enforced GEMINI.md code hygiene standards (all files <= 350 lines).
