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.FromBytes converts valid 16-byte slice to UUID
- uuid.FromBytes returns error when slice length is not 16
- uuid.UUID.MarshalText marshals UUID to standard 36-byte canonical string representation
- uuid.UUID.UnmarshalText unmarshals valid 36-byte string into matching UUID
- uuid.UUID.UnmarshalText returns error when text is invalid UUID format
