Original specular and coverage mask studies

Requires Bun with Sharp and Blender with Cycles
Keep the companion scripts together and use new output directories

bun build-specular-worldforge-inputs.ts NEW_INPUT_DIRECTORY
blender -b --python-exit-code 1 --python render-specular-study.py -- NEW_INPUT_DIRECTORY NEW_NATIVE_DIRECTORY
bun build-specular-worldforge-assets.ts NEW_INPUT_DIRECTORY NEW_NATIVE_DIRECTORY NEW_ASSET_DIRECTORY
python3 audit-worldforge-documents.py --baseline worldforge-source-audit.json

The source mask design and coverage fixture are original procedural images
The native project packs the image used for its material comparison
It saves the shader connected to Specular IOR Level with a constant roughness
The roughness render deliberately connects the same image to a different socket
No model inference calibrated reflectance recovery or WorldForge invocation is performed
Coverage counts are for one saved mask with an explicit threshold and selected region
They can include filled pixels and do not establish correctness or media acceptance
JSON formatting may differ while reproducing the same data

Independent arithmetic verification requires NumPy and Pillow
uv run --no-project --with numpy --with pillow python verify-specular-worldforge-study.py ASSET_DIRECTORY
Optional isolated save check additionally needs the pinned vggt/run_warp.py named by the audit
Pass --pinned-save-source PINNED_RUN_WARP_FILE to check that source hash and pre-encoding save arrays
