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 canonical UUID v4 string with version 4 and RFC4122 variant
- uuid.Validate accepts valid canonical UUID strings and returns an error for invalid UUID strings
- uuid.NewV7 generates a valid version 7 time-ordered UUID with RFC4122 variant
- uuid.Parse parses canonical UUID string into a 16-byte UUID value matching the original
- uuid.Nil represents the 16-byte zero UUID value
