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
- A class applying EquatableMixin compares equal and produces identical hash codes to matching instances across deep nested collections, evaluating lists order-sensitively and sets order-insensitively.
- EquatableMixin allows classes in single-inheritance hierarchies to obtain value equality and hash code parity based on overridden props.
- Nested lists in props require matching element order, whereas nested sets compare equal regardless of element insertion order.
- Deeply nested collections including maps of lists evaluate equality recursively down to leaf elements.
- Equal EquatableMixin instances properly deduplicate in Set collections and look up correctly as Map keys.
- Props containing null values or empty props lists are safely compared without runtime exceptions.
