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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. anypb.UnmarshalTo unpacks Any payload into the matching destination proto.Message
  2. anypb.UnmarshalTo resets destination message fields before unmarshaling
  3. anypb.UnmarshalTo returns error when destination message type mismatches packed type
  4. anypb.UnmarshalTo with proto.UnmarshalOptions respects options during unmarshaling
  5. Any.UnmarshalTo method unmarshals underlying message into target without explicit options
