The receipt-layer coordinate for provenance — attestation at the moment of transaction.
A substrate position naming the artifact that proves provenance was established — not a system but the verifiable document it produces.
Matched pair · sold together
Held and transacted as one position. A matched .ai + .com pair forecloses its own most common confusable — one coordinate, not two names.
Coordinated sets this position belongs to — the coverage it extends. Counts are the live cluster size in the graph.

Why this is canonical
A receipt is the proof of a completed transaction: the artifact that stands as evidence that something happened, who was responsible, and when. Pairing it with 'provenance' on .ai names the attestation artifact layer — the moment provenance crystallizes into a transferable, verifiable record. This is architecturally distinct from storage or query; it is the issuable proof.
