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

Case
HOW- Goal
- verify pkg:golang/google.golang.org/protobuf@v1.35.1
- Packages
- Created
- 2026-08-19T20:05:52Z
Contract
- proto.Marshal and proto.Unmarshal correctly round-trip protobuf messages
- proto.Equal and proto.Clone maintain message equality and deep-copy semantics
- proto.Merge merges populated fields from source message into destination
- protojson.Marshal and protojson.Unmarshal convert messages to and from valid JSON
- anypb.New and UnmarshalTo pack and unpack arbitrary protobuf messages
- structpb.NewStruct and AsMap convert between Go map structures and dynamic protobuf structs
