System One judgments (noul/choice/score) from any LLM in one prefill — a Rust, Jev-compatible /v1/systemone engine

Explore repository

How it uses Jev

System One judgments from any LLM, in one prefill. A Rust engine that answers typed questions about a piece of state — noul (yes/no), choice (one of N), score (ordered scale) — with probabilities, never generated text. Wire-compatible with TypeSafe's Jev POST /v1/systemone , and exposed to coding agents as an MCP tool.
