Recorded caveats
- Wall-clock is end-to-end workflow latency, including tools, browser automation, builds, and idle time; it is not model-only compute.
- Output tokens include hidden reasoning, generated code, and tool-call JSON, not only visible prose.
- Cache-read tokens are discounted, so total processed tokens overstate cost.
- The source receipt does not distinguish cache-write TTLs. The primary estimate follows its stated five-minute assumption; the all-one-hour alternative is included separately.
- The archive build passes, but no independent full-loop browser acceptance run, local FPS/transition-hitch receipt, final capture, or blind evaluation is archived.
Visible evidence gaps
- independent uninterrupted landing-to-orbit acceptance run
- local FPS and transition-hitch receipt with hardware details
- final viewport or browser capture
- blind-evaluation record
