Complete a checkout you created and place the order by submitting the buyer-signed payment credential. This is the MONEY-MOVING leg: funds capture on-chain to the merchant's pay_to (x402) or into escrow (Boson). The amount is re-derived server-side from the reservation, never your request, and the buyer's signature is verified before any capture. A per-buyer refusal (FORBIDDEN, cap-exceeded, FULFILLMENT_REQUIRED) returns as an error result; a missing or invalid identity is a real 401. REQUIRES IDENTITY plus a signed Idempotency-Key on a signature-required Terminal.
Input schema

| payment | object | yes | The payment container `{ instruments: [{ credential: { type, ... } }] }`, where credential.type is `x402_authorization` or `boson_commit_authorization`. Sign the seller-signed offer LOCALLY with your own wallet; Facet never holds your key. |
