Required capability and runtime proof

Capabilities

native-webgpuaccepted

capture-session WebGPUBackend device identity + raw-capture-session evidence-manifest validates under current sourceHash.

storage-bufferincomplete

origin storage is part of the camera-rig controller contract; dedicated storage binary ledger residual for full acceptance.

Runtime proof

renderer-initaccepted

capture-session reports initialized===true and active device generation.

backend-is-webgpuaccepted

rendererBackendEvidence.isWebGPUBackend===true on correctness capture-session.

mechanism-reachableaccepted

final/no-post/diagnostics presentation modes captured on the host camera-rig controller.

aligned-readbackaccepted

normalized/transport padded RGBA8 readbacks present for presentation targets.

mrt-readbackincomplete

MRT attachment recipes residual; primary presentation readbacks only on this package.

origin-storage-readbackincomplete

origin storage binary ledger residual for full acceptance.

current-adapter-gpu-timestampincomplete

timestampQueriesActive remains false for correctness profile; GPU timing is not accepted as performance evidence.

Limitations

Correctness capture records native r185 WebGPUBackend with device identity proof.
Named-adapter GPU timestamps and 60 Hz hardwarePerformance remain NOT_CLAIMED.
Primary evidence is the correctness raw-capture-session package; full mechanism/tier matrix residual.
