  "canonical_policy": "Select exactly one raw payload per trace ID only when unambiguous; never newest/best reward. Derived-only identities are labelled.",
  "missing": "Unavailable measurements are JSON null and empty CSV cells; unknown protocol is not inferred from date or current code.",
  "dates": "started_at_utc comes only from trace.timing.start. File modification times live only in sources.",
  "tokens": "Prompt/cache/completion/reasoning fields copied or strictly summed across saved calls. No synthetic total: prompt/cache accounting may differ by harness. Extra usage is retained in raw trace, not silently added. Missing call fields make exact sums null; separately named observed lower bounds sum known entries.",

  "calls": "All saved calls, including retained retry branches, not just active-branch calls. Original nodes and call links retained.",
  "protocol": "protocol_version plus protocol/task/archive/grader digests and agent configuration are required to assess comparability. One version label alone is insufficient.",
