Automated README summary
Automatically summarized from the README on 27 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A free Windows app that records, shows live, and lets you grade the answers your apps get from TypeSafe's Jev. For developers and teams who want to know how far to trust Jev on their own questions.
How it uses Jev
Tarnlight records each Jev decision (question, input, full answer) via a drop box or proxy. It shows confidence over time, latest answer, counters. You grade decisions (correct/wrong/flagged) and set bands to see how many decisions each band catches.
Technique worth stealing
Keep score: record each decision, mark whether it was right, and compare confidence to accuracy.

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.
