+"""Regression test for the admin_wipe route shim (slice 2h, #4082/#4071).
+
+The backward-compat shim at ``routes/admin_wipe_routes.py`` uses
+``sys.modules`` replacement so the legacy import path and the canonical
+``routes.admin_wipe.*`` path resolve to the *same* module object. This is
+required because ``test_admin_wipe_gallery.py`` does
+``import routes.admin_wipe_routes`` followed by
+``monkeypatch.setattr(routes.admin_wipe_routes, "SessionLocal", ...)`` and
+``"require_admin"`` — for those patches to take effect at runtime, the legacy
+module object and the canonical one must be identical.
