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
SwiftJev is a Swift package that implements SwiftDecision's DecisionBackend protocol, sending typed Noul, Choice, and Score prompts to the hosted TypeSafe Jev System One API and returning validated probability distributions for Swift apps making decisions.
How it uses Jev
Jev answers Noul, Choice, and Score prompts; SwiftJev validates each prompt and response against the Jev contracts, preserves prompt option order, and returns the full probability distribution. SwiftDecision then applies its own acceptance policy to pick the answer, with an optional maximumChoiceProbabilityGap to reject near-tie choices.
Primitives:choicescorenoul
Technique worth stealing
Thin provider adapter: validate typed prompts and responses against contracts, return full distributions, and let the caller's policy decide acceptance.
Try it
Add SwiftJev and SwiftDecision packages, set TYPESAFE_API_KEY, then create JevDecisionBackend and call engine.noul(...).
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.
