本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

契约
- Returning an empty object from a custom error map leaves the issue message undefined rather than falling back to ctx.defaultError, causing error.format() and error.flatten() to produce arrays containing undefined.
- Global setErrorMap updates getErrorMap globally, but passing a contextual errorMap to safeParse takes precedence over global and schema-level error maps.
- Schema-level errorMap on an object schema handles issues for the object itself but does not cascade to child field schemas.
- Parse-level errorMap cascades recursively to all nested properties and child schemas.
- Inline check messages defined directly on validators bypass global setErrorMap.
- Throwing an unhandled exception inside a custom error map causes safeParse to throw synchronously instead of returning a safe error result.
- Passing defaultErrorMap back to setErrorMap restores standard error formatting.
