OptionalagentId?: stringOptionalcandidateAgentId?: stringAgent id the candidate ran under, when it differs from the baseline.
OptionalcandidateWindow?: stringEvidence window covering the candidate configuration's own run (e.g. "7d"). Required: without it there is nothing real to compare.
Compares a baseline run against a candidate run.
Both sides must be real: casebook results are computed from evidence in the ledger, so the candidate configuration has to have actually run and produced evidence. Previously the candidate was never executed — its outcomes were the baseline's plus deterministic jitter — so every "candidate improves on baseline by X%" figure was invented.
