Banking and insurance lead production adoption of agentic systems, and they carry the heaviest evidentiary burden while doing it. Supervisors do not accept a demonstration. They ask for a population, sample it, and expect each sampled action to resolve to an authorized individual, a documented control, and a retained record.
The control frameworks already exist. Model risk management, change management, segregation of duties, non-repudiation, third-party oversight — none of them were written for agents, and all of them apply to agents unchanged. The failure mode is not that banks lack controls. It is that the agentic layer sits outside every one of them, in a place where the control library has no coverage and the audit trail is a vendor log.
Orcher makes the supervisory question answerable by construction. Who was authorized. What was checked. What did it cost. Where did the data go. Those four answers exist for every action, at the moment it executes, in a form that survives a three-year lookback.
