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.NewUUID generates time-based RFC 4122 v1 UUID with version 1 and RFC4122 variant
- uuid.NewRandom generates cryptographically random RFC 4122 v4 UUID
- uuid.NewMD5 produces deterministic RFC 4122 v3 UUIDs from namespace and data
- uuid.FromBytes converts a 16-byte slice into a UUID value and returns error on invalid length
- uuid.Validate verifies canonical UUID format and rejects invalid strings
- uuid.Parse and uuid.MustParse parse valid UUID strings and handle errors
