== Region Flags ==

Flags are stored as an integer bitmask in the regions table. Key flags used by GridService:

{| class="wikitable"
! Flag !! Notes
|-
| RegionOnline || Set on register, cleared on deregister (if not deleted)
|-
| Persistent || Prevents deletion on deregister -- record kept with RegionOnline cleared
|-
| DefaultRegion || Returned by GetDefaultRegions -- login destination if no other target
|-
| DefaultHGRegion || Returned by GetDefaultHypergridRegions -- HyperGrid entry point
|-
| FallbackRegion || Returned by GetFallbackRegions -- used when teleport target is unavailable
|-
| Hyperlink || Marks a HyperGrid link entry -- excluded from neighbours, returned by GetHyperlinks
|-
| NoDirectLogin || Set on HyperGrid link entries -- prevents direct login to linked region
|-
| Reservation || Holds a coordinate for a specific PrincipalID -- blocks other registrations
|-
| Authenticate || Requires token authentication on registration
|-
| NoMove || Prevents region from re-registering at different coordinates
|-
| LockedOut || Prevents registration entirely
|}

Per-region flags can be set in Robust.ini:

 Region_RegionName = +DefaultRegion,-FallbackRegion
 Region_<UUID> = +DefaultRegion

Flags are applied after DefaultRegionFlags on every registration.
