x402 Terminal-State Delivery Receipt

Payment receipts tell agents money moved. This product tells them whether the paid job reached a terminal delivery state.

Problem

An agent can pay for a job, receive a valid x402 receipt, and still get no delivered resource. A plain poller only observes silence unless the service owns an SLA clock and terminal state.

Buyer

Agent-payable API builders, marketplaces, and agent operators that need retry, refund, dispute, or route-around decisions after payment.

MVP

Terminal-state schema and JSON validator.
SLA deadline clock and `paid_unfulfilled` transition.
Receipt hash bound to actor, evidence, state sequence, and policy.
Hosted audit card for one paid job.
