Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. proto.Marshal and proto.Unmarshal correctly round-trip protobuf messages
  2. proto.Equal and proto.Clone maintain message equality and deep-copy semantics
  3. protojson.Marshal and protojson.Unmarshal convert messages to and from valid JSON
  4. anypb.New and UnmarshalTo pack and unpack arbitrary protobuf messages
  5. structpb.NewStruct and AsMap convert between Go map structures and dynamic protobuf structs
