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 structs containing Arc<T>, Rc<T>, Arc<str>, and Arc<[u8]> serialize to JSON transparently without pointer envelope overhead when serde rc feature is enabled
- assert deserializing reference-counted fields reconstructs valid data identical to the original values
- assert deserialization allocates distinct independent Arc instances for shared pointers without preserving in-memory pointer identity or strong reference counts
- assert deserializer validates inner types inside Arc and Rc and propagates deserialization errors properly
