+**Afin de** gérer des données en contexte ou synchroniser avec les notes du carnet.

-#### Critères d'Acceptation (résumé) :
-*   **Étant donné** que ma note est dans un carnet structuré, **quand** je tape `/vue`, **alors** un bloc `structuredViewBlock` s'insère avec les données réelles du carnet — aucune donnée de démo.

+| **Vue liée au carnet** | Bouton « Lier à un carnet » ou sélecteur de carnet | API schéma + notes du carnet (`notebookId`) | Table / Galerie via `StructuredViewsContainer` |
+
+#### Critères d'Acceptation :
+*   **Étant donné** une note ouverte, **quand** je tape `/database` ou `/vue`, **alors** un bloc **base locale autonome** s'insère (tableau vide éditable, pas de démo Auteurs/Œuvres).
+*   **Étant donné** un bloc local, **quand** je clique « Lier à un carnet », **alors** je peux afficher la vue structurée d'un carnet (table/galerie, données réelles).
+*   **Étant donné** un carnet lié sans schéma, **alors** callout vers le wizard — pas de crash.
+*   **Étant donné** un ancien `databaseBlock` HTML, **alors** migration vers bloc local par défaut — note charge sans crash.
