Automated README summary
Automatically summarized from the README on 11 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
OpenJevSwift is a native Swift implementation of OpenJev, the Jev-compatible "System One" decision server. It answers typed questions (noul, choice, score) about a state using model probabilities, not generated text, on Apple silicon Macs and in iPhone/Mac apps.
How it uses Jev
Jev makes decisions by reading probabilities from a model instead of generating text. For a noul question, the answer is the probability of yes; for choice or score, the probability of every option, with a confidence. The server exposes a Jev-compatible HTTP API, and the same libraries can answer requests inside an app.

Technique worth stealing
Read answers from model probabilities rather than generating text, so answers cannot go off-schema.

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.
