Automated README summary
Automatically summarized from the README on 19 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
An independent, community-maintained catalog of 992 open-source projects built with Jev, TypeSafe AI's System One model for typed decisions. It organizes entries by category such as SDKs, agent tooling, applications, games, and benchmarks, linking to public evidence for each.
How it uses Jev
The README does not describe how Jev is used in the catalog itself; it is a listing of projects that use Jev. Individual entries note the decisions Jev makes, but the catalog's own implementation is not specified.

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.
