Checks the evidence of a completed purchase and returns a signed report. audit_ucp_transaction takes the output of traveler book_flight_ucp (13 checks, plus offer_expiry and gds_identifiers when those fields are present); audit_transaction takes the evidence_bundle of supplier book_flight (9 checks, plus settlement when tx_hash is present). Proof of concept: some audit_transaction checks only confirm a field is present, and each check's detail string says so. No privileged access.
