Checks: receipt binds the request hash, names a model run id, captures the output hash before the output is used, matches the paid amount to the quoted price, sets timeout and retry gates for slow or missing responses, and classifies refund or dispute state when the run fails. Verdicts: delivery-proven, verify-more, refuse-output-with-evidence.
