Automated README summary
Automatically summarized from the README on 13 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A small, standard-library-only Go library for typed AI decisions. Define Choice, Score, and Noul questions once, evaluate them together against JSON state, and read results through typed handles. Backends include TypeSafe's Jev HTTP API and the OpenAI Decisions API.
How it uses Jev
Application code defines questions with systemone.MustChoice, MustScore, and MustNoul, then calls client.Ask with state and handles. The jev backend sends them to TypeSafe's HTTP API and returns calibrated probabilities. Results are read with Handle.In(answers), which returns typed values and errors.
Primitives:choicescorenoul
Technique worth stealing
Define typed question handles once and reuse them for both Ask and In, so answers are read through the same identity-checked handle.

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.
