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
- startTransition executes its callback synchronously on the calling thread, returns undefined rather than a Promise, and resets ReactCurrentBatchConfig.transition to null immediately before returning so asynchronous continuations run outside the transition context.
- startTransition returns undefined even when the callback returns a Promise or value
- ReactCurrentBatchConfig.transition is an active object during synchronous callback execution and is restored to null upon return
- asynchronous work scheduled inside startTransition executes after the transition context has already been reset to null
- synchronous errors thrown inside startTransition propagate immediately while reliably restoring the previous transition context
- nested startTransition calls maintain and restore the enclosing transition batch configuration
