An AI agent denied a loan application last Tuesday. The reasoning was sound — three risk signals in combination, each within policy. The decision was logged. The system moved on.
Six months later, the applicant filed a dispute. Someone pulled the record.

Nobody could say for certain. The agent had made a decision that affected a real person. The record of that decision had traveled through four systems. Nothing along the way had checked whether it arrived intact.
There is something about AI agents that makes this harder than it sounds. An agent is not deterministic. Ask it the same question tomorrow with the same inputs and it may reach a different conclusion. You cannot reconstruct what it decided by re-running it. The decision it made was made once, by a model in a specific state, with specific context it retrieved at that moment. The original record is not a copy of something you can regenerate. It is the only evidence that the decision…
