Automated README summary
Automatically summarized from the README on 18 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A workshop repo for developers and instructors: five live-executed Jupyter notebooks, a 48-slide deck with speaker notes, a cited reference, walkthrough apps, and live-build projects teaching Jev, TypeSafe AI's System One model that returns decisions instead of text.
How it uses Jev
Jev takes a state (text or JSON) plus typed questions and returns typed answers with calibrated probabilities. Notebooks and apps use Choice, Score, Noul and Box answers to branch in plain Python: routing, gating, triage, screening, and reranking decisions, with thresholds and actions owned by code.
Primitives:choicescorenoul
Technique worth stealing
Ask typed questions over a state and branch on calibrated probabilities in code, keeping thresholds and actions in plain Python rather than in prompts.
Try it
uv sync, export TYPESAFE_API_KEY, then uv run jupyter lab notebooks/ (outputs are pre-saved).
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.
