What it is
A game where you write pull request bodies to convince a reviewer to approve ten risky production requests. For developers who want to practice precise, scoped arguments under a probabilistic gate.
How it uses Jev
Each level is a typed judgement rule: a deterministic gate, a question, and a threshold. The question goes to jev-1.13.0, which returns a probability. The threshold turns that number into APPROVED or REFUSED. The verdict and number appear in the PR comments.
Primitives:score
Technique worth stealing
Pinning the model version and hashing the question so thresholds as fine as 0.25 cannot silently retune.
Try it
Use the GitHub template, clone your copy, create a branch named level-01, and open a pull request with your request in the body.
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.
