Automated README summary
Automatically summarized from the README on 27 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A TypeScript client that sends a JSON state and typed questions to TypeSafe's Jev model, returning validated decisions with probabilities. It works standalone via evaluate() or as an @intx/inference adapter for Corbits and Interchange agents.
How it uses Jev
Jev evaluates structured state against questions (choice, score, boolean/noul, box) in one POST. Each question id gets a validated decision with probabilities and confidence. Failures return a FallbackResult with a reason instead of throwing, so gates can fail closed.
Primitives:choicescorenoul
Technique worth stealing
Treat inference failures as typed data (FallbackResult with reason) rather than exceptions, enabling fail-closed gates without try/catch.
Try it
bun add @corbits/system-one @intx/inference@^0.4.0 @intx/types@^0.4.0, set TYPESAFE_API_KEY, then call evaluate().
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.
