Automated README summary
Automatically summarized from the README on 6 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A 159-call synthetic stress battery comparing Jev (TypeSafe System One) and Cloudflare Clef / Clef-flash on production-shaped decisions: ticket routing, agent triage, tool guardrails, upload triage, and candidate classification.
How it uses Jev
Jev is called via the Vercel AI Gateway evaluation-model API (plain HTTP) using the pinned evaluation-model v4 protocol. The harness sends byte-identical state and questions to each arm, maps the yes/no type keyword (noul ↔ boolean) per arm, and records raw calls, latencies, usage, and result bodies.
Primitives:choicescorenoul
Technique worth stealing
Run the identical battery twice and recompute all metrics from raw calls to separate launch-week effects from stable behavior.
Try it
cp .envrc.example .envrc; direnv allow; direnv exec . /usr/bin/python3 harness/stress.py --dry-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.
