PayeeProof checks whether a public machine payment endpoint, service identity, requested resource, and payment destination are internally consistent. It does not authorize target spending and never needs the target's payment credential.

Paid results also include an additive davisville-receipt-envelope.v1 with request, counterparty, settlement, delivery, outcome, freshness, evidence-reference, and content-integrity fields.
