 - Corriger le type Rust/TS-rs source puis régénérer les bindings ; ne pas considérer une modification manuelle isolée d’un fichier généré comme un correctif durable.
 - `kb-app-demo-desktop/src/tauri.rs` contient les attributs `#[tauri::command]`, l’enregistrement des commandes et des wrappers privés minces ; la logique complète doit vivre dans le module fonctionnel correspondant sous une fonction `pub(crate)` testable.

+- Les helpers privés de `tauri.rs` sont autorisés lorsqu’ils mutualisent exclusivement une adaptation Tauri, par exemple l’ouverture, l’affichage, le focus ou l’émission vers une fenêtre ; ils ne doivent contenir aucune logique métier, requête SQL ou orchestration de pipeline.
