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
- Pool timeout is a single-shot deadlock detector that permanently nullifies its timer after firing once, causing subsequent requests queued on a saturated pool to hang indefinitely without timing out.
- Pool constructor rejects non-positive maxAllocatedResources by throwing ArgumentError.
- The initial queued request fails with TimeoutException once inactivity exceeds the configured timeout duration.
- Subsequent requests queued on the saturated pool after a timeout event do not time out and remain pending until an allocated resource is explicitly released.
- Releasing the held resource satisfies the pending request.
- Calling release() on an already-released PoolResource throws StateError.
- Calling request() on a closed Pool throws StateError.
