The evaluation runs in this tab. Each case's state and the questions go through jevtool.dev's serverless relay to TypeSafe with your key, for this run only; nothing is stored or logged, and your expected labels never leave the browser. To keep everything on your machine, run the same suite with npx jevtool eval suite.json.
