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
- Express router.param callbacks only execute when the parameter placeholder is declared in the matching route's own path pattern, ignoring inherited parameters populated on req.params by mergeParams: true.
- req.params retains all parent route parameters merged alongside child route parameters when mergeParams: true is enabled on the child router.
- The parent router's router.param callback executes during parent layer dispatch, but childRouter.param for that same parameter name is never invoked.
