Jev DuckDB

Five self-contained Jev demos for data and analytics engineers: a LinkedIn cringe meter, semantic SQL in DuckDB, a SQL VISUALIZE intent, and dbt semantic tests locally and on Databricks, each labelled live or simulated.

A dbt package that evaluates SQL values with Jev through TypeSafe's hosted API or OpenRouter: macros expose Choice as a nullable label, Noul as a match probability and Score as a numeric rating, on DuckDB and ClickHouse.

Independent measurement of whether ORDER BY over a Jev probability is defensible, pre-registering gates on pairwise inversion, Score ordinality, calibration, and negation and paraphrase invariants.

A DuckDB extension that classifies rows in CSV, Parquet, or DuckDB tables with Jev, reported at about 10 seconds for 1,000 rows and framed as more ergonomic than a bespoke classifier.
