The cage stops what a bad message can do
The same trick message, run two ways: first with no cage, then sealed inside one.

Same message. Two outcomes.
Uncagedthe Employee did what it said, 1 file leaked, and your key was exposed.
Caged0 leaked. The file hit the wall (OpenShell), and the key stayed outside with NemoClaw, it never entered the cage.
Pairing decides who may message it. The cage decides what it can do with what it reads.
