Automated README summary
Automatically summarized from the README on 29 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A sample e-commerce app with six demos (triage, search, listing, review, glasses, esci) and 13 chapters of course material, for developers learning to integrate Jev into real EC workflows.
How it uses Jev
Jev makes typed decisions on state: triage classifies inquiries into 12 questions; search converts natural language to facets and scores candidates; listing decomposes violations into Noul; review judges input live; glasses tags 800 products with 18 tags; esci simulates automation rates. Results are probabilities used in code with thresholds and weights.
Primitives:choicescorenoul
Technique worth stealing
Decompose decisions into atomic questions, combine with code weights and thresholds, and store probabilities without collapsing to booleans.
Try it
git clone, npm install, set TYPESAFE_API_KEY in .env, node scripts/generate-glasses.mjs, npm run dev
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.
