Automated README summary
Automatically summarized from the README on 29 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A benchmark for typed System One decision models (Jev, Laya, Kev, and future ones) that read state plus typed questions and return probabilities. It measures calibration, wording sensitivity, selective prediction, ordinal fidelity, interference, and cost per decision.
How it uses Jev
Jev is one of the models benchmarked. The README does not specify how Jev is used in code; it only lists Jev 1.13.0 (hosted) among models evaluated on generated, policy-labelled manifests.
Technique worth stealing
Policy-labelled generated items with paired control arms (unknowable, label-noise, distractor, none-of-the-above).
Try it
pip install sys1bench; sys1bench suite all results/my-model --config my_model.yaml
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.
