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
A Kotlin SDK for TypeSafe AI's System One API, targeting Android (minSdk 29) and the JVM with JDK 17. It is a community port of the JavaScript SDK 0.6.0, distributed via JitPack, and not affiliated with TypeSafe AI.
How it uses Jev
Callers build typed Noul, Choice, and Score questions, pass them to client.systemOne(state) { ask(...) }, and Jev returns typed answers derived from the question types. The SDK sends the state plus questions to TypeSafe's hosted API and exposes the resulting probabilities, choice keys, and scores via result.answer(...).
Primitives:choicescorenoul
Technique worth stealing
Typed question builders whose answer types are derived statically, so result.answer(id) returns the correct answer type with no cast.

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.
