Public summary
GPT-6 Astra Low judge_pass_independently_replayed ledger: 3m 02s wall-clock, 813K processed, and $1.42 Standard API-equivalent estimate from the Codex wrapper receipt, not a subscription invoice: this was a ChatGPT-subscription run, $0 was charged and Codex emits no cost field..

Recorded caveats
- The judge measures task completion only; there is no visual quality or blind evaluation for this task.
- The replay clips are rendered by the operator's viewer from the judge's own trajectory export with a fixed camera; they are presentation evidence, not a measurement.
- Wall clock is end-to-end workflow latency including the solver's own simulation and judge runs, not model-only compute.
- Output tokens include hidden reasoning, visible prose and tool-call JSON; cache reads are discounted, so processed-token volume overstates effective cost.
- This was a ChatGPT-subscription Codex run, so there is no dollar receipt: $0 was charged and Codex emits no cost field. The dollar figure is an API-equivalent estimate at the GPT-6 Astra list rates already on record in this harness, not an invoice.
- provenance/orchestrator-results.md is the task project's own result section copied verbatim with absolute local paths replaced.
- The harness self-check archive under evidence/sim-attempts/ is committed exactly as the harness wrote it, so its attempt records still carry the operator's workspace path in their cwd field.
- The raw Codex receipts (events.jsonl, meta.json, prompt and final-message files) carry the session id, the full reasoning transcript and local paths; they are not committed, only their sha256 commitments in provenance/source-receipt-hashes.json.
- The given harness/checker exposes the judge's own scoring in-process, so the solver could self-score without the operator; wall clock and cost are NOT comparable with the dex-cube-turn-mujoco cohorts.
- usedThreeFingers / threeFingerFraction are reported, never gating.
- The judge archive and the harness archive hash the control log on different bases, so a judge attempt and the harness self-check of the SAME trajectory carry different ctrl_sha256 values; both archives are committed verbatim and the underlying .npy files were checked byte for byte.
- The harness self-check records carry passed/reason fields the harness never fills in for an unjudged simulation; those entries are surfaced with judged: false.
Visible evidence gaps
- hardware and interpreter receipt from the solver session (only the operator's replay environment is recorded)
