## Status
All empirical adversarial verifications completed with 100% PASS rate.
Preparing final 5-component handoff report with verdict: `APPROVE`.

## Completed Steps
- [x] Initialized DISPATCH.md, BRIEFING.md, progress.md.
- [x] Read `ORIGINAL_REQUEST.md` (section `## 2026-10-02T06:36:44Z`).
- [x] Read `orchestrator_17\PROJECT.md`.
- [x] Read `worker_asset_pipeline_1\handoff.md`.
- [x] Written and executed standalone adversarial verification suite `tools/verification/verify_21_drq_approved_assets_adversarial.py`:
  - 55/55 PNG images verified for strict power-of-two (2^n) dimensions and file size budgets.
  - 6/6 Tangent-Space Sobel normal maps verified for Blue mean >= 128.0 (actual range: 247.75 - 253.39) and neutral transparent padding (128, 128, 255).
  - 2/2 Emissive masks verified for non-trivial luminance (max lum 255) and matching albedo dimensions.
  - 3/3 Apple Metal Shaders verified for valid MSL syntax, headers, function entrypoints, and balanced braces.
  - 20/20 Atlas metadata JSONs verified for schema validity, request_id mapping, and frame bounding box containment.
  - 78/78 deliverables verified byte-for-byte identical in `client/webapp/assets/`.
- [x] Executed unit test suite (`pytest tests/unit/test_design_pipeline_manager.py`): 7 passed in 0.37s.
- [x] Executed E2E test suite (`pytest tests/e2e/test_asset_campaign_and_pipeline_e2e.py`): 28 passed in 34.73s.
- [x] Updated BRIEFING.md with Attack Surface and decision records.

## Next Steps
- [ ] Write final `handoff.md` with explicit verdict `APPROVE`.
- [ ] Send completion message to parent orchestrator_17.
