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
- proto.Marshal and proto.Unmarshal correctly serialize and deserialize protobuf messages
- proto.Equal and proto.Clone maintain message equality and deep-copy semantics
- proto.Merge merges populated fields from source message into destination
- proto.Size calculates the wire-format byte size of a protobuf message
- jsonpb.Marshaler and jsonpb.Unmarshaler serialize and deserialize messages to and from JSON
- ptypes.TimestampProto and ptypes.Timestamp convert between time.Time and protobuf Timestamp
- ptypes.DurationProto and ptypes.Duration convert between time.Duration and protobuf Duration
