Recorded caveats
- Wall-clock is end-to-end workflow latency, including tool execution, browser automation, builds, and user gaps; it is not model-only compute time.
- Output tokens include hidden reasoning, generated code, and tool-call JSON, not only visible prose.
- Cache-read tokens are discounted, so total processed tokens materially overstate effective cost.
- The supplied receipt declares a one-hour cache-write TTL; the primary estimate follows it and preserves an all-five-minute sensitivity.
- No standardized local FPS/hardware receipt or blind visual-evaluation record is available.
Visible evidence gaps
- candidate prompt-delivery and one-shot protocol receipt
- standardized FPS, browser, viewport, and hardware receipt
- independently authored multi-cycle acceptance suite
- blind-evaluation record
