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.

- Serialize and deserialize UUIDs via binary and text interfaces and implement database/sql driver Valuer and Scanner in google/uuid

Contract
- assert MarshalBinary serializes a UUID to 16 raw bytes and UnmarshalBinary restores the exact UUID or rejects invalid byte slice lengths
- assert MarshalText encodes a UUID into 36-byte lowercase hex string and UnmarshalText parses formatted byte slices or returns error on malformed input
- assert Value returns string representation conforming to database/sql driver.Valuer interface
- assert Scan implements database/sql sql.Scanner supporting string, 16-byte raw slice, 36-byte formatted slice, and nil inputs while rejecting unsupported types
