+# Test that library suggestions persist across file boundaries
+
+This test verifies that the default library suggestion engine set in
+`Lean.LibrarySuggestions.Default` is correctly persisted when imported via `Lean.LibrarySuggestions`.
+
+We do NOT call `set_library_suggestions` in this file - the selector should
+already be set from importing Lean.LibrarySuggestions (which imports Default).
