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
- assert uuid.NewRandom generates a valid non-nil RFC4122 version 4 UUID
- assert uuid.NewString generates a valid 36-character UUID string
- assert uuid.Parse parses a valid UUID string and matches the original
- assert uuid.Validate returns an error for invalid UUID strings
- assert uuid.Nil matches the standard zero UUID string
