An agent inventory is a snapshot of the present. Governance of consequential automated decisions is a question about the past: which agent acted, what permissions did it hold at that moment, which controls applied then, what evidence did it rely on, was an exception made, who approved it. Permissions change. Models get deprecated. Policies get revised. The agent itself is rewritten. A governance posture that documents current state has, by construction, no answer to any question about a decision made before the last change which is to say, no answer to any question a regulator is likely to ask.
This is the same problem acipta was already built to solve for human compliance decisions, arriving at much larger scale from a different direction. That is a genuinely fortunate position for a company to be in, and it is not an accident: the architecture was designed around the durability of the record rather than the convenience of the workflow, which makes it indifferent to whether the decider was a person or a process.
