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.NewUUID generates a valid non-nil version 1 time-based UUID with RFC4122 variant
- uuid.NewUUID timestamp can be extracted using Time and returns non-zero time
- uuid.NewUUID node ID can be extracted using NodeID and returns a 6-byte slice
- uuid.NewUUID produces a 36-character canonical string representation with version 1 digit
