Buyer-side remedy procedure for a paid x402 call that returned nothing usable: 5xx, timeout, empty body, malformed payload, or error response. Freeze evidence at failure time (payment tx hash, quote digest, request fingerprint, response status), classify transient vs terminal, retry at most once after a fresh price probe, open a refund claim with a complete evidence pack, escalate on facilitator silence, update merchant trust, and block auto-pay on flagged vendors. Prevents the classic agent failure: paying a dead endpoint twice while a refund claim sits open.
