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::fromString returns a LazyUuidFromString instance that implements UuidInterface but does NOT inherit from Uuid
- UuidInterface::getHex returns a Ramsey\Uuid\Type\Hexadecimal value object where is_string is false and strict comparison with a string returns false
- UuidInterface::getInteger returns a Ramsey\Uuid\Type\Integer value object rather than a string or integer primitive
- UuidInterface::getDateTime returns a DateTimeImmutable instance that implements DateTimeInterface but does not inherit from mutable DateTime
- Uuid::isValid rejects 32-character unhyphenated hexadecimal UUID strings even though Uuid::fromString successfully parses them
