 ## Benefits of This Design
 
-✅ **Flexible** - Any machine can relate to any other machine
-✅ **Bidirectional** - Dualpath works both ways automatically
-✅ **Directional** - "Controlled By" has clear direction
-✅ **Extensible** - Easy to add new relationship types
-✅ **Query-friendly** - Simple JOINs to get related machines
-✅ **Unified** - PCs are machines too, so PC-to-machine relationships use same table
-✅ **Future-proof** - Supports clusters, backups, master-slave, etc.
