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.v4(null, buf, offset) writes 16 bytes into buf at offset and returns buf (Uint8Array), not string
- uuid.v4({ random: rnd }) mutates bytes 6 and 8 in the passed random buffer to set version 4 and RFC variant
- uuid.version(str) throws TypeError when string is invalid UUID instead of returning undefined or null
- uuid.version(NIL) returns 0 and uuid.version(MAX) returns 15
- uuid.validate(buf) returns false for Uint8Array / Buffer inputs without throwing
- uuid.validate(str) returns false for 8-4-4-4-12 strings with non-RFC variant nibbles
