semantic-assert is a TypeScript testing library that uses Jev, TypeSafe's first System One model, as a judge for plain-English assertions about captured page state. It ships a semantic-assert-typesafe provider package plus Playwright and Vercel AI SDK adapters that reach Jev directly or via Vercel AI Gateway.
README 明确说明默认判定器为 Jev——TypeSafe 的首个 System One 模型，并提出通过 Vercel AI Gateway 调用 Jev；仓库包含 semantic-assert-typesafe（TypeSafe Jev provider）与 semantic-assert-ai-sdk 等实际集成包，Topics 亦含 jev 与 typesafe-ai。属于真实集成 Jev API/SDK 的可用测试工具，非空仓库或关键词堆砌。
