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 returns a valid RFC 4122 version 4 UUID with nil error
- uuid.Validate confirms validity of canonical 36-character UUID string and rejects malformed strings
- uuid.Parse decodes valid UUID string into 16-byte UUID struct
- uuid.ParseBytes parses valid 36-byte slice into matching UUID struct
- uuid.MustParse returns parsed UUID without panic on valid input and panics on invalid input
- uuid.FromBytes converts 16-byte slice to UUID and returns error for slice length not equal to 16 bytes
- uuid.UUID URN formats UUID into standard urn:uuid prefix format
