| Local usability and shared meaning | Keep local tools while connecting the claims actually consumed by others. |
| Fast summary and adequate grounds | A shared status is useful only when its question and basis remain recoverable. |
| Constituent success and encompassing result | Inspect the combination and any condition the parts cannot establish alone. |
| Continuity and changed premises | Preserve history and unaffected results while reopening affected reliance. |
| Coordination and administrative burden | Match the shared account to the real dependence; stop adding fields when conversation suffices. |
