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 public research guide synthesizing literature and proposing experiment designs for System One decision models (Jev, Laya) versus rules, classifiers, and encoders on classification and entity-matching tasks. It targets researchers evaluating whether typed decision models add value.
How it uses Jev
The guide describes Jev as TypeSafe's hosted typed-decision API, where the application supplies state, a question, and allowed outcomes, and a typed result feeds application logic. It proposes experiments comparing Jev against baselines; no model was downloaded, trained, or queried, and no benchmark results are reported.

Technique worth stealing
Compare decision models with simple baselines on the same records and select using error cost, review effort, deployment constraints, and measured performance.
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.
