A Closed-World Interface Resolver

What it explores

Generative interfaces are usually painted: a model writes markup and we hope it's right. This experiment treats the interface as a decision instead. A deterministic resolver reads the intent, the model's confidence, and the risk of the action, then picks parts from a fixed registry — nothing outside the registry can appear, whatever the inputs. The same decision then renders three ways: for a screen, for voice, and as a structured payload for a customer's own AI agent. Change the inputs and watch the decision, the rules that fired, and the interface move together. No model call is involved, which is the point: interpretation can be probabilistic, but what the interface is allowed to become shouldn't be.

The argument behind it: The Interface Is a Decision
