The rule

An agent’s freedom is four levels in words a person can act on (asks first, edits on its own, a second model checks, full trust), as four cards with one line each. Under them, always in view, the four things that ask at every level: spending money, a password or key, deleting something, and messaging someone new. The floor is enforced on the server, not drawn as an option.
