Cost basis
- Primary cost uses 5-minute cache writes (supplied primary calculation).
- All-1-hour cache-write alternative: $63.65.

Recorded caveats
- Wall-clock time is end-to-end latency, not model-only compute time.
- Output tokens include hidden reasoning, generated code, and tool-call JSON.
- Cache-read tokens are billed at a deep discount, so total processed tokens overstate effective cost.
- The primary total uses the supplied five-minute cache-write rate; using one-hour cache writes would yield $63.65.
- The static source bundle was archived without a fresh browser run in this environment; browser/hardware conditions, local FPS, final capture, and blind evaluation remain unavailable.
Visible evidence gaps
- browser and hardware environment
- local FPS measurement receipt
- final capture
- blind-evaluation record
