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.NewRandom generates a valid RFC 4122 v4 UUID with Version 4 and Variant RFC4122
- uuid.NewUUID generates a valid RFC 4122 v1 time-based UUID with Version 1
- uuid.NewV6 generates a valid RFC 9562 v6 UUID with Version 6
- uuid.NewV7 generates a valid RFC 9562 v7 UUID with Version 7
- uuid.NewSHA1 generates deterministic RFC 4122 v5 UUIDs from namespace and name
- uuid.Parse and uuid.Validate parse and validate canonical UUID strings
- uuid.MustParse parses valid UUID strings and panics on invalid input
- uuid.FromBytes parses a 16-byte slice and rejects slices with invalid length
- uuid.NullUUID supports database SQL Value and Scan operations and JSON serialization
