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 with Version 4 and Variant RFC4122
- uuid.NewRandom generates a valid UUID v4 and returns no error
- uuid.NewString returns a 36-character canonical string representation of a v4 UUID
- uuid.NewUUID generates a time-based RFC 4122 v1 UUID with Version 1
- uuid.NewV6 generates a reordered time-based RFC 9562 v6 UUID with Version 6
- uuid.NewV7 generates a time-ordered RFC 9562 v7 UUID with Version 7
- uuid.NewSHA1 generates deterministic RFC 4122 v5 UUID from namespace and name
- uuid.Parse and uuid.Validate validate valid UUID strings and reject invalid input
- uuid.MustParse returns UUID for valid string and panics on invalid input
- uuid.FromBytes converts a 16-byte slice to UUID and validates length
- uuid.NullUUID supports database SQL Value and Scan operations and JSON serialization
