What it is
A local server that answers typed Choice/Score/Noul questions with probabilities and confidence, compatible with the official Jev SDK. For developers who want to test Jev-style decisions without a waitlist or API key.
How it uses Jev
Jev makes decisions by scoring a state and typed questions (Choice, Score, Noul) to return calibrated probabilities. The server uses open weights (e.g., Qwen) to compute logprobs, and the result is used as confidence in code via POST /v1/systemone.

Technique worth stealing
Temperature-fit calibration on open-weight logprobs for Jev-compatible confidence.
Try it

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.
