Can your infrastructure prevent an agent from running without being registered?

Knowing what’s running today is one thing. Making it structurally impossible to deploy an unregistered agent is another. The first is inventory. The second is governance.

The difference matters because inventory is a snapshot — accurate at the moment you take it, outdated the moment someone spins up a new agent. Structural prevention means the infrastructure itself enforces registration: no registration, no execution. The agent cannot run without being known.

This is the same principle that applies throughout the PAC framework: policy says what shouldn’t happen; architecture makes the unwanted thing impossible. If your governance relies on people following process, it will fail exactly when the pressure is highest and the shortcuts are most tempting.
