Validation evidence
- Result: PARTIAL_MODEL_SUPPLIED_SHADERTOY_RUNTIME_EVIDENCE
Recorded caveats
- The bounded root task is not strict one-shot and its derived timing includes root-task work outside a pure model-only generation interval.
- Output includes hidden reasoning, visible response content, code, and tool-call JSON.
- Cache reads are discounted, so total processed tokens overstate cost.
- Cache creation is zero because the transcript schema does not expose a cache-write token field; this is not proof of no cache writes.
- The local supplied runtime evidence and independent static compile are not a Shadertoy performance measurement.
- No initial/optimized local FPS pair, RTX Pro 6000 1080p60 final capture, or blind evaluation is archived.
Visible evidence gaps
- strict one-user-turn protocol
- initial and optimized local FPS under identical uncapped conditions
- RTX Pro 6000 1080p60 final capture with GPU and frame-rate metadata
- blind evaluation record
