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
- assert a pin_project struct containing an unannotated PhantomPinned field silently implements Unpin allowing safe in-place dereferencing via Pin::new and Pin::get_mut
- assert annotating a PhantomPinned field with #[pin] or applying #[project(!Unpin)] disables automatic Unpin implementation and requires unsafe Pin::new_unchecked construction
- assert a pin_project enum with unannotated PhantomPinned variant fields implements Unpin as long as its #[pin] variant fields implement Unpin
- assert project_replace moves out unpinned fields into ProjOwn while replacing the pinned struct and dropping pinned fields in-place
- assert projection types and project methods generated for pub structs have pub(crate) visibility rather than public export
