Automated README summary
Automatically summarized from the README on 9 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A step-by-step course that teaches JEV, TypeSafe AI's decision model, by building a customer-support assistant called Desk Buddy. Each step compares a JEV-based version with an LLM-only version on speed, cost, and accuracy.
How it uses Jev
JEV answers typed questions (Choice, Score, Noul) about a customer message. For example, a Choice question picks the support team; a Noul question checks urgency; a Score question rates frustration. The returned probabilities and choices are used in code to route, guard, or judge.
Primitives:choicescorenoul
Technique worth stealing
Split work: JEV for fast decisions, LLM for writing, code for exact calculations.

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.
