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.NullUUID with Valid true returns UUID string value from Value method
- uuid.NullUUID with Valid false returns nil value from Value method
- uuid.NullUUID Scan populates valid UUID and sets Valid true for valid string or byte input
- uuid.NullUUID Scan sets Valid false and Nil UUID when scanning nil value
- uuid.NullUUID Scan returns error for invalid string or malformed byte input
- uuid.NullUUID MarshalJSON serializes to JSON string when valid and null literal when invalid
- uuid.NullUUID UnmarshalJSON parses JSON UUID string and handles null JSON literal
