# Merged With Auth

Union-merges XWUISuperDB with a sibling Auth Super-app via `XWUISuperApp.merge(...)`, mounting the JSON-shaped descriptor into a base XWUISuperApp as `extraTree` / `extraPages` so DB and Auth groups share one sidebar (landing stays `db-dashboard`). The Auth side is an inline `AppAuthDemo` subclass (Dashboard / Login / Register / Users / Key Admin leaves over XWUIEmpty) standing in for the parallel `XWUISuperAuth`; when it ships, swap the class and the merge call site is unchanged.
