Data & Search MIT E2 · source reviewed

A single-user research monitor where code fetches and versions evidence, Jev screens and scores it, and Qwen drafts cited notes for human review.

JEV · Decision point

For each (fetched source, open research question) pair, Jev answers Noul gates (on topic, method transferable, evidence compatible) and then Score dimensions through Pydantic AI's native `typesafe:` model; deterministic code applies the thresholds and routes each pair to keep / review / drop.

Links source-level judgments to versioned questions and human labels; threshold fitting writes proposals rather than silently changing policy.
