• Payment provider. Bring authoritative authorization, capture, refund and void events into payment evidence with their provider identifiers and references.

Choose the authoritative provider event for each payment effect and restrict who can mark it verified.

Keep a stable operation key for retries and check the expected revision before accepting a write. A receipt reaches completed only after the local effects and authoritative evidence match. Review discrepancies without repeating the external action.
