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.

Contract
- UUID.MarshalBinary encodes UUID to a 16-byte binary slice and UnmarshalBinary decodes it back
- UUID.UnmarshalBinary returns error when input byte slice length is not 16
- UUID.MarshalText encodes UUID to a 36-byte text representation and UnmarshalText decodes valid textual UUID
- UUID.UnmarshalText returns error when input byte slice is not a valid UUID string
- UUID.Value returns driver.Value as 36-character string representation
- UUID.Scan parses string and byte slice database representations into UUID and rejects unsupported types
