## Definitions

### `com.publicdomainrelay.temp.market.receipts.x402`

**Type**: `record`

Proof-of-payment receipt minted by the bidder in response to a successful x402-gated GET against the bids.x402 url. Returned (by AT-URI + CID) to the requester, which uses it as the payload of the higher-level com.publicdomainrelay.temp.market.accept so the bidder can verify payment before provisioning.

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `cid` | `string` (cid) | Yes | badge.blue attestation CID over the referenced accepts.x402 record, making this receipt a remote attestation proof: computed from the accepts.x402 record (signatures stripped), this receipt's metadata (cid/signatures stripped, repository = requester's repo DID added) as $sig, via DAG-CBOR + SHA-256 + CIDv1. Re-binding the proof-of-payment to a copy of the accepts.x402 in another repository fails verification — badge.blue's replay-attack prevention applied to payment receipts. |
| `accept` | `ref` → `com.atproto.repo.strongRef` | Yes | Strong reference to the com.publicdomainrelay.temp.market.accepts.x402 record that this payment settles. |
| `signatures` | `ref` → `network.attested.signature#signatures` | Yes | badge.blue attestations over this receipt. Must include the bidder's inline signature, attached at creation, so the proof-of-payment is non-repudiable. |
