  "notes": "Scene Optimizer was unavailable in the selected runtime and the user declined install, so the workflow ran in structural-only mode: structure assessment plus pre-mutation USD validation only. No mesh operations executed and no optimized stage was written, so the verdict is neutral. FPS, frame time, and VRAM are unmeasured; re-run Phase 1a/6a in full mode under Kit / USD Composer / Isaac Sim to graduate the verdict.",

Structure assessment characterized the stage and pre-mutation USD validation ran, but without SO there is no optimized output to compare against the baseline. The score reflects a neutral, no-change result rather than a measured optimization win.\n\nThe report documents the runtime blocker and the next capture needed so a later full-mode run can produce a real before/after verdict.",
