Jev System One — Visual Playground

A desktop playground for composing & evaluating the TypeSafe primitives — Choice, Score and Noul.

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

TypeAsksReturns
choiceWhich of these options?choice, probabilities, confidence
scoreWhich level on a rubric?score, legend, probabilities, confidence
noulIs this statement true?noul (0–1)

Features

[VISUAL + RAW] — Build with guided forms; inspect or edit the exact JSON payload in parallel tabs.
[ADD + LIST] — Add unlimited questions; each one appears in the Loaded Questions list with per-row delete.
[LIVE EVALUATION] — Token-based matching of state against every primitive.
[PRESETS] — Choice (Routing), Score (Rubric) and multi-question Noul (Yes/No) starter packs.
