+# Ticket 105 — Glisser-déposer des extractions vers le graphe
+
+## Objectif
+
+Permettre de prendre une extraction depuis `Dossier → Extractions` et de la
+déposer dans le graphe afin de créer ou compléter les liens de l’enquête.
+
+## Fonctionnement attendu
+
+1. Une extraction sélectionnée dans la Sidebar peut être déplacée.
+2. Le graphe accepte le dépôt uniquement sur une zone valide.
+3. Une fenêtre de confirmation affiche le fichier, sa source et son contenu
+   textuel disponible.
+4. L’utilisateur choisit explicitement :
+   - créer une nouvelle entité à partir de l’extraction ;
+   - rattacher l’extraction à une entité existante ;
+   - annuler.
+5. L’association est enregistrée en base et visible dans la fiche concernée.
+6. Une relation graphique peut être créée sans déplacer ni dupliquer le
+   fichier original.
+
+## Contraintes
+
+- Ne jamais créer de relation silencieusement.
+- Refuser les fichiers hors du dossier de l’enquête.
+- Conserver les associations déjà présentes.
+- Utiliser les API GTK de glisser-déposer et les commentaires Doxygen prévus
+  par le projet.
+
+## Critères d’acceptation
+
+- Un fichier `.txt` d’OSINT est déplaçable depuis la Sidebar.
+- Le dépôt sur le graphe ouvre le dialogue de choix.
+- L’entité ou l’association créée survit à la réouverture de l’enquête.
+- Les dépôts annulés ne modifient ni la base ni le graphe.
+- Tests unitaires des chemins invalides, du choix d’action et de la
+  persistance.
+
+## Vérification
+
+```sh
+make -j2
+make test
+```
