Automated README summary
Automatically summarized from the README on 7 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A learning and testing record for Jev (TypeSafe System One), a judgment model that returns typed probabilistic answers. Includes concept docs, 5 runnable demos, and reproducible benchmarks for developers evaluating Jev.
How it uses Jev
Jev answers typed questions (Noul, Choice, Score) on a given state, returning probabilities and confidence. Demos use these for triage, guardrails, reranking, function calling, and file selection. Code branches on answers and confidence.
Primitives:choicescorenoul
Technique worth stealing
Speculative fan-out: ask all possible questions in one call, then let code select relevant answers.
Try it
Set TYPESAFE_API_KEY, install requirements, run demo/jev_lite.py or bash demo/run_all.sh.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
