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 unconfigured global text map propagator silently injects zero headers into carrier
- assert unconfigured global text map propagator silently ignores incoming traceparent header and returns unlinked context
- assert downstream span created from unconfigured extraction context generates a disconnected new trace ID
- assert explicitly configured TraceContext and Baggage propagator injects W3C headers
- assert configured propagator extracts remote span context with matching TraceID and remote flag
- assert downstream span links to upstream parent TraceID and parent SpanID when propagator is configured
- assert ParentBased sampler preserves sampling decision for remote sampled parent context
