How Sophon works, room by room.

A model call is stateless: it forgets, it dies with its process, and it does what the prompt says. Sophon adds the three layers a model doesn't come with. State is an entity graph you can read, correct, and delete. Execution is a Graph-mode run that checkpoints each transition, so it comes back at the step it stopped on. Authority is risk levels, approval gates, and a credential vault outside the model, where it cannot argue with them.

Around them sit the surfaces you reach it from, every way in held to the same gates, and the ways you extend it.
