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.

HOW- Goal
- verify pkg:golang/github.com/google/uuid@v1.6.0
- Packages
- Symbols
-
- github.com/google/uuid.MarshalBinary
- github.com/google/uuid.UnmarshalBinary
- Environment

Contract
- uuid.MarshalBinary encodes UUID into 16-byte raw slice without error
- uuid.MarshalBinary encodes uuid.Nil into 16 zero bytes
- uuid.UnmarshalBinary decodes 16-byte binary data into UUID
- uuid.UnmarshalBinary decodes 16 zero bytes into uuid.Nil
- uuid.UnmarshalBinary rejects byte slices with length other than 16 with error
- uuid.MarshalBinary and uuid.UnmarshalBinary round-trip accurately preserves UUID value
