Overview
A WinForms (.NET 10) playground that evaluates typed questions against a state document and renders the structured answers — visually and as raw JSON. Jev evaluates questions in parallel: one request, one structured response, no text parsing.
Primitives
| Type | Asks | Returns |
|---|---|---|
| choice | Which of these options? | choice, probabilities, confidence |
| score | Which level on a rubric? | score, legend, probabilities, confidence |
| noul | Is this statement true? | noul (0–1) |
