shadow-parityincompletevisible and cast-shadow materials share the owner-masked deformation node; current-source atlas evidence is pending
current-adapter-performanceincompleteINSUFFICIENT_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.
