The README opens with
Idiomatic Java 17+ client library for TypeSafe AI's Jev System One decision engine.
Everywhere a primitive takes a string, it also accepts a structured value. Plain strings keep working exactly as before; use structured values when you need to give Jev richer context. See the advanced primitives docs.
Rubric and ScoreLevel are typed helpers, but any Map/List works too, so nested category maps and custom keys are supported. Constructors taking plain strings (new Noul(name, "question"), new Score(name, "q", "low", "high")) are unchanged.
