What it is
JevSQL adds TypeSafe Jev judgments to SQLite, letting you compare records by meaning, select exact evidence from text, rank retrieved passages, route uncertain results to review, and detect when a changed source invalidates an earlier decision. It runs as a Node library or CLI with zero runtime dependencies.
How it uses Jev
JevSQL uses Jev to make decisions on database rows: jev_choice classifies rows into categories, jev_noul returns a yes-probability, jev_bool returns a boolean, jev_match estimates entity equivalence, and jev_pick selects an exact source span. Results are used in SQL queries and materialized as ordinary SQLite tables.

Technique worth stealing
Materialize Jev decisions as ordinary SQLite tables with incremental refresh, caching, and cost guards.
Try it
npm test; npm run workflows; node bin/jevsql.mjs demo
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.
