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 serializes a proto.Message into wire-format bytes and roundtrips with proto.Unmarshal
- proto.Marshal produces standard protobuf length-delimited wire encoding for StringValue
- proto.Marshal serializes an empty protobuf message into zero bytes
- proto.MarshalOptions.Deterministic produces reproducible binary output
- proto.MarshalOptions.MarshalAppend appends encoded message to an existing byte buffer
- proto.Size returns the exact byte length produced by proto.Marshal
- proto.Marshal on nil proto.Message returns empty bytes without error
