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 semaphore.Weighted enforces strict FIFO ordering so smaller Acquire requests remain blocked behind a larger head waiter even when sufficient unallocated tokens exist
- assert TryAcquire returns false whenever waiters are queued in the wait list even if unallocated capacity is available
- assert canceling a blocked head waiter context immediately unblocks subsequent queued waiters without requiring an additional Release
- assert calling Acquire with an already-canceled context returns context.Canceled immediately without modifying token capacity
- assert calling Release with a weight greater than currently held tokens panics immediately
