Automated README summary
Automatically summarized from the README on 29 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A local workbench for experimenting with TypeSafe's System One model Jev. It lets users organise experiments in projects, edit them with live validation, paste inputs, run them, and compare past runs, from a SvelteKit UI or the terminal.
How it uses Jev
Each experiment is a JSON file with a state and typed questions. Jev answers every question with calibrated probabilities instead of free text. Only model, state and questions are sent to Jev after #{…} and ${…} are filled in; results are shown as cards and ranked views.
Primitives:choicescorenoul
Technique worth stealing
Treat an experiment as state plus typed questions, and use noul for independent yes/no checks alongside choice for best-fit selection.
Try it
npm install, set JEV_API_KEY in .env, then npm run dev.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
