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 v4({ rng: () => Math.random() }) throws TypeError when given a scalar random float callback
- assert v4({ rng: byteSupplier }) returns a valid v4 UUID string with RFC4122 version and variant bits applied
- assert v4(options, buf, offset) writes raw bytes directly into buf and returns the buffer reference instead of a string
- assert stringify(buf, offset) decodes the canonical UUID string from the binary buffer
- assert v4(options, buf, offset) throws RangeError when target buffer is smaller than 16 bytes
