Automated README summary
Automatically summarized from the README on 28 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Python evolution simulation for researchers probing whether an AI judgment model's pairwise answers can sustain coevolution. Seven islands evolve English-described creatures; a separate predator-prey world tests arms races against no-interaction, fixed-predator and shuffled controls.
How it uses Jev
Jev answers narrow probability questions on creature phrases: can this creature catch and eat that one, find food, survive the habitat and hard season, and fit the habitat. Kill, survival and breeding probabilities are computed from those answers by ordinary Python that never reads phrase meaning.
Primitives:choicescore
Technique worth stealing
Replace a fitness function with a judgment model's pairwise probabilities, then run a time-shift test and additive-fit controls to show the interactions, not per-animal scores, drive the cycles.
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.
