+- **Jointure côté client.** Une recommandation ne porte que `alert_id`, jamais `site_id`, et
+  `GET /recommendations` n'a aucun filtre. `app-recommendation-list` (`shared/components/`) charge
+  donc en parallèle `GET /alerts` (filtré par `site_id` quand un site est fixé) et
+  `GET /recommendations`, puis les joint par `alert_id` (`joinByAlert`, fonction pure testée à
+  part). Les recommandations dont l'alerte n'est pas dans le jeu chargé sont ignorées : c'est ainsi
+  que le filtre site s'applique. `/alerts` n'étant pas paginé, un seul appel suffit.
+- **Paramètres d'URL.** `?site=<site_id>` présélectionne le filtre site ; `?alert=<alert_id>`
+  réduit la vue à une alerte et la met en évidence (entier strictement positif, sinon ignoré).
+- **Génération.** Le bouton « Générer les recommandations » n'apparaît que pour le rôle `admin`
+  (`POST /recommendations/generate?site_id=`, réservé admin côté API) et affiche le bilan renvoyé
+  (créées, déjà présentes, alertes examinées) avant de recharger la liste. La voie normale reste le
