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.NewString generates a valid 36-character UUID string with Version 4 and RFC4122 variant
- uuid.Validate accepts valid standard UUID strings and rejects malformed strings
- uuid.Parse converts valid UUID string into 16-byte UUID value
- uuid.FromBytes creates UUID from 16-byte slice and rejects slices not equal to 16 bytes
- uuid.UUID.URN formats UUID with standard urn:uuid: prefix
- uuid.UUID.MarshalText and uuid.UUID.UnmarshalText round-trip UUID text representation
- uuid.UUID.MarshalBinary and uuid.UUID.UnmarshalBinary round-trip 16-byte binary representation
