# DISPATCH — challenger_asset_pipeline_1

## Identity
- Role: Adversarial Asset Quality Challenger
- Working directory: `c:\Projects\FreeExile\.agents\teamwork\challenger_asset_pipeline_1\`
- Parent: orchestrator_17 (`a51efd02-6b77-4f96-b8ee-621b750c7e54`)

## Mission & Inputs
Read `c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md` (specifically section `## 2026-10-02T06:36:44Z`).
Read `c:\Projects\FreeExile\.agents\teamwork\orchestrator_17\PROJECT.md`.
Read `c:\Projects\FreeExile\.agents\teamwork\worker_asset_pipeline_1\handoff.md`.

## Adversarial Verification Tasks
Write and execute empirical adversarial verification scripts to stress-test the asset deliverables:
1. Inspect all 78 deliverables in `assets/approved/<DRQ-ID>/` across all 21 DRQs (`DRQ-20261001-*`).
2. Adversarially verify all 55 PNG images:
   - Check file headers, decode using PIL.
   - Assert dimensions $(w, h)$ are strictly powers of two ($w > 0 \land (w \& (w-1)) == 0$).
   - Assert file sizes do not exceed size budget (< 150KB or < 2MB).
3. Adversarially verify all 6 Tangent-Space Sobel Normal Maps:
   - Load RGB channels as numpy arrays.
   - Calculate Blue channel mean: assert $\mu_B \ge 128.0$.
   - Test transparent pixel padding ($R=128, G=128, B=255$ on $\alpha=0$).
4. Adversarially verify both Emissive Masks:
   - Verify non-empty luminance masks matching diffuse dimensions.
5. Adversarially verify all 3 Apple Metal Shaders:
   - Verify non-empty `.metal` files with valid MSL syntax, kernel/vertex/fragment signatures.
6. Adversarially verify all 20 Atlas Metadata JSON files:
   - Parse via `json.loads`.
   - Verify presence of required keys (`request_id`, `texture_width`, `texture_height`, frames/slices).

Provide an explicit verdict: `APPROVE` or `REQUEST_CHANGES`.

## Output
Write your report to `c:\Projects\FreeExile\.agents\teamwork\challenger_asset_pipeline_1\handoff.md`.
Send a completion message back to orchestrator_17 (`a51efd02-6b77-4f96-b8ee-621b750c7e54`).

Perform adversarial empirical verification of all 78 deliverables in assets/approved/:
- Write and run verification script to check power-of-two dimensions (2^n) on all 55 PNGs.
- Calculate and verify Blue channel mean >= 128.0 on all 6 normal maps.
- Verify emissive masks, Metal shaders, atlas metadata JSON schemas, and file size budgets.
Provide an explicit verdict (APPROVE or REQUEST_CHANGES) in c:\Projects\FreeExile\.agents\teamwork\challenger_asset_pipeline_1\handoff.md.
