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

Controller must await WebGPURenderer.init() and reject a backend where isWebGPUBackend is not true; no fallback is activated.

single-scene-renderincomplete

Frame execution must report exactly one scene render and no duplicate diagnostic or presentation render.

no-post-processingincomplete

Runtime graph and frame record must report zero post-processing passes.

mobile-resource-accountingincomplete

Named-device sustained evidence must report CPU/GPU/presentation timing, render items, submissions, shadow casters, materials/pipelines, and peak live bytes.

Runtime proof

renderer-initincomplete

Await controller readiness after WebGPURenderer.init().

backend-is-webgpuincomplete

Capture controller metrics with nativeWebGPU true.

physical-routesincomplete

Load all 15 scenario/mechanism/tier/camera physical routes and prove each locks exactly one route dimension.

mechanism-reachableincomplete

Load every final, blockout, hierarchy, materials, and action-ready mechanism route and bind the observed controller mode to the physical route record.

target-contractsincomplete

Capture protected node, socket, ColliderConstructionInput, destruction-group, mode, tier, and exact-reset inventories for all three targets.

render-ownershipincomplete

Capture one renderer owner, one scene render, one tone-map owner, one output-transform owner, and zero post-processing passes.

aligned-readbackincomplete

Capture the actual integer WebGPU row stride, 256-byte alignment, compact width, height, and normalized render-target pixels for every required PNG.

visual-contractsincomplete

Inspect final and diagnostic PNGs for each target and record AI-vision authored-contract scores; no reference-image similarity claim is permitted.

sustained-performanceincomplete

Record named-device sustained CPU/GPU/presentation evidence and mobile resource accounting without inventing a universal frame target.
