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.

Case
HOW- Goal
- verify DCE security domain and ID extraction with github.com/google/uuid.UUID.Domain
- Packages
- Symbols
-
- github.com/google/uuid.Domain
- github.com/google/uuid.UUID.Domain
- github.com/google/uuid.UUID.ID
- Created

Contract
- Domain.String returns "Person", "Group", "Org" for standard DCE domains and formatted fallback for custom values
- UUID.Domain returns Person, Group, and Org domain for Version 2 DCE security UUIDs
- UUID.ID returns the 32-bit local execution environment identifier embedded in Version 2 DCE security UUID
- UUID.Domain and UUID.ID correctly decode domain byte and big-endian 32-bit ID from arbitrary UUID values
- uuid.Nil returns Domain(0) for UUID.Domain and 0 for UUID.ID
