 ## DUP-003 · Score 88 · Formatage de dates UI
 - **Motif** : fonctions utilitaires de formatage (`toLocaleDateString`/`Intl.DateTimeFormat`) recopiées dans plusieurs pages (catalogues modèles et documents).
 - **Occurrences détectées** :
-  - `app/pages/models/components.vue` — lignes 70-311 (affichage de la colonne « Modifié »).
-  - `app/pages/models/pieces.vue` — lignes 70-310.
+  - `app/pages/component-catalog.vue` — lignes 70-311 (affichage de la colonne « Modifié »).
+  - `app/pages/pieces-catalog.vue` — lignes 70-310.
   - `app/pages/documents.vue` — lignes 90-188.
 - **Extraction** : utilitaire commun `app/utils/date.ts` exposant `formatFrenchDate(value: Date | string | number | null | undefined): string` avec gestion des valeurs nulles/invalides.
 - **Plan / Statut** : toutes les pages importent `formatFrenchDate` et l’utilisent directement en template. Plus de fonction locale dupliquée.
