Public summary
GPT-5.6 Sol Ultra partial_token_timing_source_build_static_acceptance_ledger ledger: 1h 29m 57.7s wall-clock, 29.32M processed, and $20.84 Official OpenAI standard API-list-price equivalent; not an itemized Codex Pro subscription charge.

Recorded caveats
- Wall-clock is end-to-end workflow latency, including tools and idle time, not model-only compute.
- Output tokens include hidden reasoning, visible prose/code, and tool-call JSON.
- Cache-read input is deeply discounted, so total processed tokens overstate cost.
- This is an API-equivalent estimate rather than the actual charge for a Codex Pro subscription-backed session; separately priced tools and non-token services are excluded.
- The acceptance evidence is model-authored static/server-rendered testing plus a fresh build and lint run. No independent full-loop browser playthrough, FPS/hitch receipt, or final runtime capture is supplied.
- The supplied social preview is retained for provenance but is not used as a final render or quality score.
- No blind-evaluation record is supplied.
Visible evidence gaps
- independent uninterrupted orbit-to-surface-to-orbit acceptance run
- local FPS and transition-hitch receipt with hardware details
- final browser or viewport capture
- blind-evaluation record
