Required capability and runtime proof

Capabilities

native-webgpuaccepted

CDP Google Chrome Metal capture; evidence-manifest bound to sha256:0a63491b4d4001ff2bef75e7a00c05ba887642cdb15d58643d1cd02f6a41e560; validate:artifacts PASS; deviceIdentityVerified.

storage-buffersincomplete

src/tsl/pose-storage.js defines pose, root, and owner-inclusive candidate storage; current-source readback evidence is pending

Runtime proof

renderer-initaccepted

playwright-cdp-chrome correctness session on existing Chrome :9222 with WebGPUBackend device identity + 10 presentation PNGs.

native-backendaccepted

playwright-cdp-chrome correctness session on existing Chrome :9222 with WebGPUBackend device identity + 10 presentation PNGs.

candidate-certificationincomplete

candidate-set-sweep and raise-k-policy-fixture prove frozen-corpus K/storage agreement on CPU; GPU binding recapture is pending

render-target-readbackaccepted

playwright-cdp-chrome correctness session on existing Chrome :9222 with WebGPUBackend device identity + 10 presentation PNGs.

shadow-parityincomplete

visible and cast-shadow materials share the owner-masked deformation node; current-source atlas evidence is pending

current-adapter-performanceincomplete

INSUFFICIENT_EVIDENCE: frozen hero/crowd/background 60 Hz profiles and a timestamp-query measurement API now exist, but current-source profile artifacts are pending and the runtime still identifies its geometry as a diagnostic owner-masked shell. The legacy measureSteadyFrames submission proxy is explicitly ineligible for acceptance. A 2026-07-11 browser audit measured the same approximately 33.3 ms requestAnimationFrame baseline with the render loop active and paused; the fail-closed evaluator rejects that host cadence.
