Automated README summary
Automatically summarized from the README on 20 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Starter examples for developers trying TypeSafe's Jev System One model. Includes a ticket-triage example and a re-ranking example, each with sample data and a Makefile, runnable through OpenRouter without an early-access key.
How it uses Jev
In 01, one ticket is state; seven named questions (department Choice, business_impact Score, threatens_churn Noul, etc.) are sent in a single parallel request, and the typed answers drive a routing policy written in code. In 02, each (question, article) pair is its own state with one Noul; calls fan out concurrently and the returned probability is the sort key.
Primitives:choicescorenoul
Technique worth stealing
Pick the primitive by what the answer means, and keep policy thresholds in code rather than in the model.
Try it
git clone, make setup, cp .env.example .env with an OpenRouter key, then make test and make run.
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.
