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 choose_multiple_weighted on all zero weights returns Ok with empty slice instead of InsufficientNonZero error
- assert choose_multiple_weighted returns Ok with all available non-zero items when requested amount exceeds positive weights
- assert index sample_weighted returns Ok with all available positive-weight indices when requested amount exceeds non-zero weights
- assert negative weights still return Err(WeightError::InvalidWeight)
