+  - wings can be nested via parent/child relationships to represent sub-wings
+  - ships now carry behavior metadata such as command, mining, escort, screen, or logistics
+  - fleet orders fan out into ship-level execution orders, keeping "order" separate from "behavior"

 - Orders currently supported:
   - move
   - transfer

 - Docking was added as a required step for transfer to stations
 - Stations have limited docking capacity and explicit docking ports
+- Carriers now act as mobile docking hosts for smaller combatants
+- Carrier recovery was corrected so docking ships reserve a pad early and approach the moving pad directly instead of stalling behind the hull
