Automated README summary
Automatically summarized from the README on 6 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
An independent community project for learning how TypeSafe AI's Jev decision model fits into software. It provides a support-routing CLI, local browser playground, keyword baseline, versioned experiment config, offline replay, and diagnostic metrics.
How it uses Jev
Jev answers three typed questions about a support ticket: Department (Choice: billing, technical, sales, other), Urgent? (Noul: 0–1 yes probability), and Frustration (Score: weighted position on 0–2 rubric). The application policy routes to review if department is 'other' or confidence is below 0.8; urgency and frustration do not trigger actions.
Primitives:choicescorenoul
Technique worth stealing
Use typed questions (Choice, Score, Noul) to get structured decisions instead of conversational prose, then apply your own policy.
Try it
npm test && npm start, then open http://127.0.0.1:3000. Or npm run demo, npm run eval, node playground.mjs replay.
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.
