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 generates a valid version 4 UUID with RFC4122 variant
- uuid.Parse parses valid canonical UUID string into UUID value
- uuid.Parse returns error on invalid UUID strings
- uuid.MustParse parses valid UUID string and panics on invalid input
