"""Audit du 2026-10-02, B03 : `download --from cloud --hub X` ne téléchargeait
rien et répondait 0. La CLI passait `modules=[]` à toute source cloud, et le
filtre du moteur (réseaux autorisés par le hub) éliminait alors tous les clips.
Chaîne CLI complète (analyse des arguments, sélection des modules, moteur) ; seuls
le réseau Blink et le transfert sont simulés."""
