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.Version returns Version 1, 4, 5, and 7 for respective UUID versions
- UUID.Variant returns RFC4122 for standard generated UUIDs
- UUID.Version and UUID.Variant identify version and RFC4122 variant from parsed UUID strings
- uuid.Nil returns Version 0 and Reserved variant
