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
- FuturesOrdered executes queued futures concurrently but yields completed items strictly in the order they were pushed, returning Poll::Pending when successor futures finish before preceding ones and buffering their results for immediate subsequent delivery once predecessor futures complete.
- Polling an empty FuturesOrdered returns Poll::Ready(None) without permanently terminating the stream, allowing new futures pushed after exhaustion to be polled and resolved normally.
- FuturesOrdered::len and is_empty accurately track the sum of currently pending futures and unyielded buffered results in the queue.
