What it is
A community Spring Boot 4 starter that lets Spring MVC applications ask TypeSafe Jev typed questions through an injected JevClient, using RestClient and Jackson 3.
How it uses Jev
JevClient.evaluate takes state plus a map of Choice, Score, or Noul questions and returns calibrated probabilities. Code reads answers via response.choice("team").choice(), response.noul("urgent").noul(), or response.score("severity").score(). The application decides thresholds.

Technique worth stealing
Inject one JevClient; back off when the application supplies its own; no HTTP calls during startup.
Try it
./mvnw clean install, set TYPESAFE_API_KEY, run examples/support-triage with spring-boot:run.
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.
