Primitives

Choice, Score, and Noul: three question shapes, three answer shapes, zero vibes-based parsing.

What it does

The doc page that finally separates the primitives: when to ask for a discrete label, a graded score, or a structured Noul object, and what comes back on the wire. Read it once and stop treating every Jev integration like a chat completion with extra steps. Your future self will thank you when thresholds live in code, not in prompt footnotes.

Choice vs Score vs Noul, explained like you are shipping gates this quarter, not writing a taxonomy paper.
