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
- timestamppb.New converts time.Time into *timestamppb.Timestamp with Seconds and Nanos normalized to UTC, correctly mapping zero time and sub-second nanoseconds.
- timestamppb.Timestamp.AsTime converts the protobuf message back to time.Time in UTC, and calling AsTime on a nil receiver safely returns time.Unix(0, 0).UTC().
- timestamppb.Timestamp.CheckValid and IsValid validate timestamp bounds from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z and reject negative or overflowing nanoseconds.
- timestamppb.Timestamp supports protobuf wire serialization and protojson serialization formatting as an RFC 3339 string.
