Les listes paginées (utilisateurs, classes, matières, affectations, invitations parents, droits à l'image) effectuaient des requêtes SQL complètes à chaque chargement de page, sans aucun cache. Sur les établissements avec plusieurs centaines d'enregistrements, cela causait des temps de réponse perceptibles et une charge inutile sur PostgreSQL. Cette refactorisation introduit un cache tag-aware (Redis en prod, filesystem en dev) avec invalidation événementielle, et extrait les requêtes de lecture dans des ports Application / implémentations DBAL conformes à l'architecture hexagonale. Un middleware Messenger garantit l'invalidation synchrone du cache même pour les événements routés en asynchrone (envoi d'emails), évitant ainsi toute donnée périmée côté UI.
