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 Set#<=> returns nil when neither set is a subset of the other rather than ordering by size or elements, causing Array#sort across disjoint sets to raise ArgumentError
- assert Set#<=> returns -1, 0, or 1 only when sets have a subset, equality, or superset relationship
- assert relational operators <, <=, >, >= on disjoint sets evaluate to false in both directions rather than establishing an ordering
- assert subset and relational comparison methods raise ArgumentError with 'value must be a set' when passed an Array, while set algebra methods (+, -, &, |, ^) accept any Enumerable
- assert Set#<=> returns nil when comparing a Set with an Array
