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.New generates a non-nil RFC 4122 v4 UUID value
- uuid.NewString generates a valid RFC 4122 v4 UUID string
- uuid.Parse parses a valid UUID string and returns error for invalid string
- uuid.Validate validates valid UUID string format and rejects invalid formats
- uuid.MustParse returns UUID on valid string and panics on invalid string
- uuid.FromBytes parses a 16-byte slice into a UUID value and returns error on invalid length
- uuid.NewSHA1 generates deterministic RFC 4122 v5 UUIDs from namespace and data
- uuid.NewV7 generates a version 7 UUID with RFC4122 variant and ordered timestamps
- uuid.NullUUID handles valid and null UUID values with JSON serialization
