Automated README summary
Automatically summarized from the README on 27 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A repository of pre-registered studies testing whether language models remember how market events turned out, so that backtests measure memory rather than judgment. It publishes code, per-call probabilities, and freeze proofs, but withholds licensed data.
How it uses Jev
In the Jev study, TypeSafe Jev (`jev-1.13-20260917`) is asked to predict whether each of 12,533 US earnings announcements beat expectations, comparing each company only with itself. The README does not say how Jev is called or how its probabilities are used in code.
Technique worth stealing
Pre-registering the protocol and anchoring a freeze file in Bitcoin before any model call.
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.
