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
- SpanLimits passed with uninitialized zero values to WithRawSpanLimits truncates all string attribute values to empty strings and drops all events and links because zero values are applied verbatim rather than falling back to defaults
- WithSpanLimits replaces any zero or negative limit field with default values (128 for counts and -1 for unlimited value length), preventing explicit disabling of limits
- NewSpanLimits reads hierarchical environment variables with span-specific overrides (OTEL_SPAN_ATTRIBUTE_COUNT_LIMIT taking precedence over OTEL_ATTRIBUTE_COUNT_LIMIT) and defaults to -1 for value length and 128 for counts
- AttributeValueLengthLimit truncates scalar string attributes and individual string slice elements to the configured byte limit while leaving non-string attributes and event/link attributes un-truncated
- AttributeCountLimit tail-drops excess span attributes incrementing DroppedAttributes, while EventCountLimit and LinkCountLimit evict oldest entries FIFO incrementing DroppedEvents and DroppedLinks
- AttributePerEventCountLimit and AttributePerLinkCountLimit tail-drop excess attributes on individual events and links incrementing DroppedAttributeCount
