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
- Uuid::uuid5(Uuid::NAMESPACE_DNS, 'example.com') generates deterministic UUIDv5 'cfbff0d1-9375-5685-968c-48ce8b15ae17' matching both string constant and UuidInterface namespace arguments
- Uuid::uuid5 rejects arbitrary non-UUID namespace strings and 16-byte raw binary with InvalidUuidStringException
- RFC 4122 requires concatenating 16 binary network bytes of namespace with name, differing completely from naive sha1 string concatenation
- Uuid::uuid3 generates MD5-based UUIDv3 with version nibble 3, distinct from SHA-1 UUIDv5 for the identical namespace and name
- Name-based UUIDs reject time-based getDateTime() calls with UnsupportedOperationException
