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. ErrorInfo fields Reason, Domain, and Metadata store structured error details and are accessible via GetReason, GetDomain, and GetMetadata getters.
  2. ErrorInfo getters return safe zero values (empty strings and nil map) when called on nil or zero-initialized ErrorInfo receivers.
  3. ErrorInfo serializes and deserializes accurately with proto.Marshal and proto.Unmarshal, preserving all message fields.
  4. ErrorInfo messages support deep copying with proto.Clone and semantic equality checks with proto.Equal.
  5. ErrorInfo.Reset clears all fields back to zero state.
