Recorded caveats
- The judge measures task completion only (facelet state, alignment, contact pads, runtime limits); there is no visual quality or blind evaluation for this task.
- The replay clip is rendered by the operator's viewer from the judge's trajectory export with a fixed camera; it is presentation evidence, not a measurement.
- provenance/orchestrator-results.md is the orchestrator's own result table copied verbatim and retains the operator's workspace paths.
- Wall clock is end-to-end workflow latency including the solver's own simulation and judge runs, not model-only compute.
- Grok token counts are not available from the grok-sub receipt; only the xAI usage dollars, elapsed seconds and turn count were recorded.
- Both tier-1 cohort solutions exploit the pre-positioned D grasp; tier 1 does not test finger placement, which is why the stage-2 task exists. Do not compare the tiers.
- Reconstructed attempts are this run's own progression, recovered and judged after the fact by the archive operator. They are unscored evidence: they do not change this run's verdict or cohort standing and are excluded from every comparison, including any of them that the judge passes.
Visible evidence gaps
- hardware and interpreter receipt from the solver session (only the operator's replay environment is recorded)
- token-count receipt (xAI usage dollars only)
Public result only
This result keeps its public summary and evidence, but it does not currently have a matching Builder test with prompts, projects, Harness workflows or skills.
