What it is
huncho is a TypeScript SDK for developers to define decisions as code. It asks typed questions of a decision model, applies thresholds with hysteresis, nests decisions, journals every one, replays policy changes without inference, and calibrates against outcomes.
How it uses Jev
huncho uses Jev via providers (direct, OpenRouter, Vercel AI Gateway). It asks typed questions (Noul, Choice, Score) of Jev, receives probabilities, and applies thresholds with hysteresis to produce named decisions. The result is used in code as decision.outcome, decision.via, and decision.previous.

Technique worth stealing
Hysteresis thresholds with enter/exit values to prevent flapping, per key.
Try it
npm i huncho, then run examples with TYPESAFE_API_KEY set: node --env-file-if-exists=.env.local dist/examples/support-route.js
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
