One claim, the sentence we would accept, the attribution, and a receipt a reader can verify. Copy it the way your document needs it. Agents get the same card as JSON: GET https://frc-mcp.ziyetis.workers.dev/cite/<claim-id>.

⟦FRC:id:value:hash:channel⟧ is a serial number for the figure: the hash covers the claim object behind it, the channel says which door it left by (this page issues c). The channel is an analytics label outside the hash, not proof of where a copy was used: a verify request on a c receipt shows that someone checked a card receipt, which could be us; evidence that a card was used elsewhere is the receipt appearing in an outside document. Paste the receipt into /verify at any later date: current means the figure has not changed; stale routes you to the correction. Spec: Proof Object 0.1.
