Automated README summary
Automatically summarized from the README on 6 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A set of JSON request files plus a tiny Python client for Jev, TypeSafe's System One model. It is for developers who want to send text and typed questions to the System One API.
How it uses Jev
Each file is the body of POST https://api.typesafe.ai/v1/systemone: a model, a state (the text), and questions. Jev reads the text, answers from a list you wrote, and says how sure it is. The client sends these requests and prints the reply.
Primitives:choice
Technique worth stealing
Keep a pile of example request files and trust them over any single run, since numbers can move between runs and model versions.
Try it
No key: paste any demos/ file into the TypeSafe playground. With a key: cp .env.example .env, then python3 try_jev.py.
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.
