Trust Receipt Verify API
Verify a BlindOracle receipt against the parts a buyer cannot check alone: is the proof_id really in BlindOracle's append-only proof rail, does its payload still hash to the stored row, and does the row's HMAC-SHA256 verify against the signing key. Also recomputes content_sha256 and confirms the Base payment, so one call is a complete answer. Deterministic, no LLM. The self-checkable half is free forever in the published verify-blindoracle-receipt skill (RQ-BO-RECEIPT-VERIFY-01).
