The absence of a rule is not cover.
A safe harbor is a published standard you can meet and then point to. When a regulator declines to write one for agentic AI, there is nothing to meet — and nothing to hide behind. Examiners still examine. Discovery still discovers. The question in the deposition is unchanged: who authorized this automated decision, and prove the record wasn't altered.
“The model guidance doesn't apply” is not an answer to that question. It removes a framework you could have cited; it removes nothing examiners or plaintiffs can ask.
