Pour fiabiliser la transformation, définissez d’abord les schémas Zod d’entrée et de sortie. Utilisez `z.optional()` avec `.default()` pour les champs nullables, et `z.preprocess()` pour les conversions de format (ex: string → Date). Testez chaque étape de validation séparément avant d’intégrer la logique métier.
