Automated README summary
Automatically summarized from the README on 10 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Measures whether Jev (TypeSafe AI's System One model) can beat the market price on resolved Polymarket Yes/No markets, using the market price as baseline. For prediction-market bot developers evaluating Jev as a cheap, fast judge.
How it uses Jev
For each market, Jev answers one Noul question ('this market resolves Yes') in two states: blind (question + resolution rules) and priced (same plus Yes price at T−24h). A Choice question selects the category. Results are scored with Brier score, log loss, AUC, and a paper-trade check.
Primitives:noulchoice
Technique worth stealing
Compare Jev's probabilities to market prices using Brier score, log loss, AUC, and a logistic blend with cross-validation.

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.
