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
- pgtype.UUID represents PostgreSQL UUID values with Bytes [16]byte and Valid bool fields
- pgtype.UUID implements sql.Scanner parsing 36-character hyphenated and 32-character hex UUID strings and handling nil as invalid
- pgtype.UUID implements driver.Valuer returning formatted UUID string for valid UUIDs and nil for invalid UUIDs
- pgtype.UUID.String returns hyphenated 36-character UUID string when valid and empty string when invalid
- pgtype.UUID provides native ScanUUID and UUIDValue conversion methods
- pgtype.UUID marshals to and unmarshals from JSON quoted UUID strings and null
- pgtype.Map encodes and scans pgtype.UUID in PostgreSQL text and binary wire formats
- sample helpers provide structured creation, parsing, formatting, wire format encoding/decoding, and JSON conversion
