Automated README summary
Automatically summarized from the README on 3 Nov 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Jevlar is a small self-hosted Go gateway between applications and decision-model APIs speaking the System One wire format. It handles caller authentication, provider and key selection, retries, and usage accounting from one TOML file, with no database or UI.
How it uses Jev
Jevlar forwards System One decision requests (Choice, Noul, and other question types) to configured providers such as TypeSafe, Upstage, Ollama, OpenRouter, or Kev. It picks a healthy provider and key, retries elsewhere on failure, and splices the target model id into the request while forwarding other bytes unchanged.
Primitives:choicenoul
Technique worth stealing
Route each model alias across multiple providers with priority or fastest policy, retrying on failure and cooling rate-limited keys.
Try it
mise install && mise run check, then go run ./cmd/jevlar --config configs/minimal.toml
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.
