WebGPU Procedural Creature Lab

Interactive Three.js WebGPU/TSL demo for WebGPU Procedural Creature Lab, with 7 scenarios, 8 mechanisms, and 3 quality tiers and evidence-gated validation.

Evidence status: The implementation is available for technical review, but its native-WebGPU runtime and evidence gates remain incomplete.

P0Storage Buffers capability proof

src/tsl/pose-storage.js defines pose, root, and owner-inclusive candidate storage; current-source readback evidence is pending
capabilityRequirements.storage-buffers
P0Candidate Certification runtime proof

candidate-set-sweep and raise-k-policy-fixture prove frozen-corpus K/storage agreement on CPU; GPU binding recapture is pending
runtimeProof.candidate-certification
P0Shadow Parity runtime proof

visible and cast-shadow materials share the owner-masked deformation node; current-source atlas evidence is pending
runtimeProof.shadow-parity
P0Current Adapter Performance runtime proof

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.

P2Close tier-specific acceptance

Validate and promote hero, crowd, background as independent visual and performance contracts without crossing their protected invariants.
