This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- durationpb.New converts time.Duration into *durationpb.Duration with corresponding Seconds and Nanos fields, where negative durations have both negative Seconds and negative Nanos.
- durationpb.Duration.AsDuration converts the protobuf message back to time.Duration, and calling AsDuration on a nil receiver safely returns 0.
- durationpb.Duration.CheckValid and IsValid validate duration bounds within +/-10,000 years and reject sign discrepancies between Seconds and Nanos or out-of-range nanoseconds.
- durationpb.Duration supports protobuf wire serialization and protojson serialization formatting as a string with a trailing 's' suffix.
