Required capability and runtime proof

Capabilities

native-webgpuaccepted

correctness capture-session + evidence-manifest (current sourceHash) validates; WebGPUBackend deviceIdentityVerified; validate:artifacts structuralVerdict PASS; non-solid presentation readbacks with material-difference pairs.

storage-computeaccepted

field-atlas compute dispatches + patch-analytic-bounds storage compute recorded in pipeline-graph/mechanism-metrics during correctness capture; atlasConsumed true on patch contract.

Runtime proof

render-target-readbackaccepted

10 standard presentation PNGs at 1200x800 RGBA8 with aligned row strides; final/no-post/temporal/seed pairs pass evidence-v2 material-difference thresholds.

pipeline-graphaccepted

pipeline-graph.json records scene submissions, field-atlas bake/mip dispatches, and patch-analytic-bounds compute from the validated correctness session.

resource-ledgeraccepted

resident-resources/render-targets/storage-resources written for interleaved patch geometry + field atlas storage during correctness capture.

Limitations

Current-source correctness capture after interleaved vertex packing + adapter maxBufferSize request; validate:artifacts structuralVerdict PASS.
GPU timestamps NOT_CLAIMED; visualCorrectness and lifecycle remain INSUFFICIENT_EVIDENCE; not a publishable release-bundle.
Root cause fixed: separate BufferAttributes exceeded WebGPU max vertex buffers (16>8); geometry is now one InterleavedBuffer.
