Jev Spring

Java 21 client for the System One (Jev) API, with sync and async HTTP clients, typed Noul, Choice, and Score questions, error mapping, and retries. A second Maven module auto-configures Jev as a Spring AI Model.

Spring AI Community's TypeSafe starter puts Jev behind seven Spring AI SPIs: judge, self-refine advisor, guardrail advisor, document filter, reranker, tool index, and evaluator.

Christian Tzolov plugs JevDocumentFilter and JevDocumentReranker into Spring AI's Modular RAG pipeline: four Noul questions per chunk drop injections, contradictions, and noise before a one-question reranker keeps the top three.
