The README opens with

Elixir client for System One decision models: TypeSafe Jev, Cloudflare Clef, OpenRouter's decisions endpoint, and anything self-hosted that speaks the /v1/systemone wire format (for example CLM).

You send a state (any JSON) and a map of typed questions; you get back typed answers with their full probability distributions, never collapsed to a single pick. That is what a router or a gate needs: top-k over a Choice, a threshold on a Noul, a level cut on a Score.
