Recorded caveats
- The judge measures task completion only; there is no visual quality or blind evaluation for this task.
- Wall-clock includes tools, simulation and judge runs, and idle gaps; it is not model-only compute.
- One OpenCode agent turn contains many billable model requests; visible output and reasoning are separate output-priced fields; cache reads are deeply discounted so total processed tokens overstate cost.
- OpenRouter billed $0 (BYOK Alibaba key); the OpenCode-recorded $0.2616 is a catalog-rate estimate. The receipt's own billing block wrongly equates it with marginal cash because the extractor assumes pay-as-you-go credits.
- The counted run is a clean single session; three earlier launches aborted instantly on the max_tokens cap before the project opencode.json fix and are not counted (archived privately).
- The solver submitted a gravity-compensated 3 s hold after its turn attempts failed; the log is violation-free and fails only the target-state checks.
- Attempt archiving was not yet in this tier's judge for this run (fixture revision v1); the three reconstructed attempts under evidence/reconstructed-attempts/ were re-run by the operator after the fact from the solver's own scripts, judged FAIL, and are not scored.
Visible evidence gaps
- hardware and interpreter receipt from the solver session (only the operator's replay environment is recorded)
- judge-time attempt archive (only the after-the-fact reconstruction exists)
