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 Span::record updates a field declared with tracing::field::Empty and the event observes the entered span scope
- assert a per-layer Targets filter captures the allowed target while excluding a higher-severity event from an unlisted target
- assert a nested with_default replaces rather than composes with the outer dispatcher, then restores the outer dispatcher when its closure returns
- assert a with_default dispatcher is thread-local and is not inherited by a thread spawned inside the scoped closure
- assert events emitted after the outer with_default closure returns are not delivered to either scoped capture
