Is a UI design based on state-machines where you're restricted from performing certain actions based on the current state. For example a logged-in user can do everything a logged out user can do. An admin can do everything a logged-in user can do. There's a [see page 18, hierarchy] of permissions and access control.

This model suggests a sub-state machine nested inside a logged-in super-state.
