warped-sys1-lab

Local SvelteKit workbench and CLI for organizing, editing, running and comparing Jev experiments defined as JSON.

CLIbeta

Overview

warp-sys-one is a local lab for experimenting with Jev. An experiment is a JSON file with a piece of state and a set of questions; Jev answers each with calibrated probabilities. The lab organizes experiments into projects, edits them with live validation, accepts pasted inputs through ${name} placeholders and file variables, runs them, and compares past runs, from a Matrix-style SvelteKit UI or the terminal.

Other features include ranked summary views, cases, validation rules, private experiments and an HTTP API. It needs Node 22+ and a TypeSafe key, read server-side only and never sent to the browser. Inputs can be filled through placeholders or file variables, ranked summary views compare answers, and an HTTP API exposes the same experiments to other tools.

How it works

  1. Create an experiment JSON with state and questions.
  2. Fill inputs and run from the UI or CLI.
  3. Inspect probabilities and ranked views.
  4. Compare runs over time.

Strengths

  • Organizes many experiments with validation.
  • UI and CLI share the same format.
  • Key stays server-side.

Caveats

  • A workbench, not a production component.
  • Requires a TypeSafe key.

Getting started

npm install, cp .env.example .env (set JEV_API_KEY), npm run dev
