Promoted same-lab media

No same-lab evidence image is promoted for this report. The page intentionally shows status and proof requirements instead of substitute art.

Required capability and runtime proof

Capabilities

native-webgpuincomplete

src/lab/browser-app.js blocks unless renderer.backend.isWebGPUBackend is true; current-source capture is pending

storage-buffersincomplete

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

Runtime proof

renderer-initincomplete

src/lab/browser-app.js awaits renderer.init() before capability checks; matching source-hash evidence is pending

native-backendincomplete

src/lab/browser-app.js requires renderer.backend.isWebGPUBackend === true; matching source-hash evidence is pending

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-readbackincomplete

captureFrame implements integer 256-byte-aligned WebGPU readback; current-source images are pending

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.
