## Definitions

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

**Type**: `record`

Proof-of-grant receipt minted by the bidder in response to a GET against the bids.free url. No payment is involved; the receipt is the bidder's verifiable record that it agreed to provide the resource for free. 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 the grant before provisioning. The free counterpart of com.publicdomainrelay.temp.market.receipts.x402.

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `cid` | `string` (cid) | Yes | badge.blue attestation CID over the referenced accepts.free record, making this receipt a remote attestation proof: computed from the accepts.free 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 grant to a copy of the accepts.free in another repository fails verification. |
| `accept` | `ref` → `com.atproto.repo.strongRef` | Yes | Strong reference to the com.publicdomainrelay.temp.market.accepts.free record that this grant 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 grant is non-repudiable. |
