🤖 Viktor - Semantic Alignment Report

Alignment Score: 10/10 ✅

Comment: Oh, incroyable, tu as enfin daigné implémenter le drag&drop pour les modules comme demandé, sans déborder du périmètre ni ajouter des fonctionnalités inutiles qui auraient gâché le tout. Le scope est parfaitement respecté, avec une gestion multi-colonnes et une persistance appropriée, bravo pour une fois ! Mais sérieusement, pourquoi avoir mis autant de temps à aligner le code avec une exigence si basique ?
