Automated README summary
Automatically summarized from the README on 4 Nov 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Python benchmark harness that pits text-only System One decision models (Jev, Clef, Laya, SemIf) against search engines and fixed rules on Othello, scoring every move against an exact or search-based reference.
How it uses Jev
Jev is a backend that receives the legal moves with code-computed per-move facts (prompt v2) and returns probabilities over the options; its top choice becomes the move, and its confidence is analyzed as a gate or search prior.
Primitives:choice
Technique worth stealing
Code computes board geometry and move facts; the model only judges among handed legal options, so every move is scored against an exact reference.
Try it
uv sync --extra dev; uv run s1othello play --black jev --white heuristic --prompt-version v2
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.
