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
- 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
