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 generated __eq__ does direct attribute comparison, so an instance containing NaN is not equal to itself even though Python tuple comparison shortcuts on identity
- assert attrs.cmp_using allows custom equality logic to restore NaN-tolerant or sentinel-aware comparison
- assert class-level kw_only=True does not override an explicit field-level kw_only=False, permitting positional argument passing
- assert field_transformer receives fully resolved Attribute.alias strings and Attribute.alias_is_default flags before transformer execution
- assert attrs.fields directly accepts an instance as well as a class
- assert attrs.Converter with takes_self receives preceding fields during __init__ but only sees subsequent fields during post-init assignment
- assert __attrs_pre_init__ receives the actual positional arguments passed to __init__ rather than their default values
