UI Is a Projection of Runtime State
Interfaces should reflect what the system is actually doing.

Most AI interfaces are designed as conversational fronts, with the underlying system state hidden behind a chat bubble. That framing is comfortable but misleading: when the system is doing real work, operators need to see real state.
### State, Not Persona
A UI should answer three questions at any moment: what is the system doing, what does it know, and what is it allowed to do. Personas, avatars, and conversational flourishes do not answer those questions; they obscure them.
### Projection, Not Invention
When the interface reflects actual runtime state — active agents, current tools, pending approvals, recovery points — operators can trust what they see. When the interface invents state to feel friendlier, trust collapses the first time the projection diverges from reality. Ex1 is built on the assumption that UI is a projection layer over a governed runtime, not a costume worn by it.
