# 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).
