# Merged With DB

Demonstrates `XWUISuperApp.merge(...)` against `XWUISuperAuth`. Until the sibling `XWUISuperDB` lands, the example inlines a small `AppDBDemo` subclass - a Database group with the seven KEYSTONE-aligned leaves - so it stands alone today; swapping `AppDBDemo` for `XWUISuperDB` later is a one-line import change. The union descriptor is mounted on a host `XWUISuperApp` as `extraTree` / `extraPages`, opening on `auth-dashboard` with the Database group rendered beneath the Auth group.
