Automated README summary
Automatically summarized from the README on 23 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Fourteen packages bringing TypeSafe Jev, a System One decision model returning calibrated probabilities, to agent harnesses (OMP, Pi, Claude Code), MCP clients, GitHub Actions, CLIs, VS Code, and Python.
How it uses Jev
Jev answers typed questions (noul, choice, score) over a state such as a diff or tool call; callers read probabilities via noul(), score(), and choice() and act on them in their own code, keeping thresholds and side effects local.
Primitives:choicescorenoul
Technique worth stealing
Batch many independent typed questions against one state, since batching is nearly free and answers are evaluated independently.

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.
