+# Ticket #013
+
+## Titre
+
+Intégrer `InvestigationTreeView` dans la `Sidebar`.
+
+---
+
+## Objectif
+
+Afficher dans la barre latérale l'arborescence complète de l'enquête ouverte.
+
+Le composant `InvestigationTreeView` existe déjà. Ce ticket consiste uniquement à l'intégrer dans `Sidebar` et à lui transmettre le modèle métier reçu.
+
+---
+
+## Architecture
+
+```text
+Application
+    │
+    ▼
+MainWindow
+    │
+    ▼
+Sidebar
+    │
+    ▼
+InvestigationTreeView
+    │
+    ▼
+GtkTreeListModel
+```
+
+La `Sidebar` héberge la vue.
+
+Elle ne parcourt jamais directement le système de fichiers.
+
+---
+
+## Responsabilités
+
+### Sidebar
+
+Le module `Sidebar` doit :
+
+- créer un `InvestigationTreeView` ;
+- intégrer son widget racine sous le titre ;
+- transmettre le `InvestigationTreeModel` au composant ;
+- libérer la structure `InvestigationTreeView` lors de sa propre destruction.
+
+### InvestigationTreeView
+
+Le composant conserve ses responsabilités actuelles :
+
+- adapter le modèle métier à GTK4 ;
+- afficher les nœuds ;
+- gérer l'ouverture et le repli des dossiers.
+
+---
+
+## Principe de propriété
+
+`Sidebar` est propriétaire de :
+
+```text
+InvestigationTreeView
+```
+
+Elle doit donc appeler :
+
+```c
+investigation_tree_view_free(...)
+```
+
+lors de sa destruction.
+
+En revanche, ni `Sidebar` ni `InvestigationTreeView` ne possèdent :
+
+```text
+InvestigationTreeModel
+```
+
+Le modèle reste la propriété de `Application`.
+
+---
+
+## Fichiers concernés
+
+```text
+src/widgets/sidebar.c
+```
+
+Éventuellement :
+
+```text
+include/widgets/sidebar.h
+```
+
+uniquement si l'API publique doit être précisée.
+
+Aucun changement du Core n'est nécessaire.
+
+---
+
+## Modifications attendues
+
+La structure privée `Sidebar` doit contenir :
+
+```c
+InvestigationTreeView *tree_view;
+```
+
+Le constructeur doit :
+
+1. créer le composant ;
+2. récupérer son widget racine ;
+3. l'ajouter sous le titre ;
+4. lui permettre d'occuper l'espace disponible.
+
+La fonction :
+
+```c
+sidebar_set_tree_model(...)
+```
+
+doit transmettre le modèle à :
+
+```c
+investigation_tree_view_set_model(...)
+```
+
+Le titre de la `Sidebar` peut continuer à afficher le nom du nœud racine.
+
+---
+
+## Interface graphique attendue
+
+```text
+Template
+
+▸ 00_BaseDeDonnees
+▸ 01_Preuves_Originales
+▸ 02_Preuves_traitees
+▸ 03_Chronologie
+▸ 04_Entites
+...
+```
+
+Les dossiers peuvent être développés et repliés.
+
+Les fichiers apparaissent dans les branches développées.
+
+---
+
+## Hors périmètre
+
+Ce ticket ne doit pas :
+
+- permettre la sélection d'un nœud ;
+- afficher des icônes ;
+- ouvrir un fichier ;
+- ajouter un menu contextuel ;
+- rafraîchir automatiquement l'arbre ;
+- modifier le système de fichiers ;
+- communiquer avec SQLite.
+
+---
+
+## Contraintes techniques
+
+- GTK4 uniquement ;
+- aucun `GtkTreeView` ;
+- aucune lecture directe du disque dans `Sidebar` ;
+- aucun transfert de propriété du modèle métier ;
+- aucun état global ;
+- documentation cohérente ;
+- compilation sans warning ;
+- aucun `Gtk-CRITICAL`.
+
+---
+
+## Critères d'acceptation
+
+- [ ] Le projet compile sans warning.
+- [ ] `make test` reste entièrement valide.
+- [ ] La vue est intégrée dans la `Sidebar`.
+- [ ] Le titre affiche le nom de l'enquête.
+- [ ] Tous les dossiers racine apparaissent.
+- [ ] Les branches peuvent être développées et repliées.
+- [ ] Les fichiers apparaissent dans les branches.
+- [ ] L'ouverture successive de deux enquêtes reconstruit correctement l'affichage.
+- [ ] La fermeture ne produit aucun warning critique.
+- [ ] Le Core n'est pas modifié.
+
+---
+
+## Tests manuels
+
+1. Lancer l'application.
+2. Ouvrir le dossier `Template`.
+3. Vérifier l'affichage des dossiers racine.
+4. Développer `00_BaseDeDonnees`.
+5. Vérifier la présence de `Enquete.sqlite`.
+6. Développer plusieurs niveaux.
+7. Fermer l'application.
+8. Rouvrir avec une autre enquête.
+9. Vérifier que l'ancien arbre a disparu.
+10. Lancer `make test`.
+
