How does an AI agent payment get authorized and recorded?

Fritz wired his agent Nigel straight to the rail: one call, money out. The day a payee tripped a watchlist, the request had already left — no screen stood between the instruction and the wire, and nothing wrote the entry down.

Tyson ran Nigel through five steps, in order. Authorize: Nigel signs only as authorized signer on the human-owned Wyoming series LLC, capped, with a named human as Member and Manager behind him. Screen: the payee is checked against watchlists. Clear-at-rail: the bank confirms the instruction. Post: a double-entry is written, debit and credit. Audit: the trail is recorded. The flow is fail closed — if any step does not pass, the payment stops there and nothing later runs. When a payee failed the screen, that step returned a reject and the four downstream steps never ran. Caps and order are documented structure, not a guarantee; the series form is newer and less court-tested than older entities.
