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
- ParentBased(NeverSample()) samples and exports child spans when the context contains a sampled remote parent, because ParentBased delegates sampled remote parents to AlwaysSample() by default rather than the configured root sampler.
- ParentBased(AlwaysSample()) drops and suppresses child spans when the context contains an unsampled remote or local parent, because ParentBased delegates unsampled parents to NeverSample() by default.
- Only root spans without a valid parent context evaluate the root sampler passed to ParentBased.
- ParentBased.Description() returns a composite string reflecting the root sampler and all four default sub-samplers.
