What it is
An unofficial operator-level showcase for TypeSafe Jev, aimed at developers building classify, route, score, or verify steps. It provides a Python operator lab, a smart-home fan-out demo, a TypeScript harness CLI, and agent skills.
How it uses Jev
Jev answers typed questions (Choice, Score, Noul) over a given state in one call. The lab and examples show fan-out, confidence routing, composite scoring, and guardrails, with code owning the workflow and side effects.
Primitives:choicescorenoul
Technique worth stealing
Fan-out: many typed questions, one state, one call — roughly 12× cheaper than serial.
Try it
git clone the repo, pip install -r requirements.txt, python app.py, then open http://127.0.0.1:7872.
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.
