A component with no .stp could mean two different things: the CAD source was never found in the index at all, or it's indexed but nobody exported the STEP yet. Cross-references the missing codes against cad_index.db (reusing the phase-2 verification cache when available) and reports each as EsitoStep.StepMancante vs ComponenteNonTrovato, colored differently.
