+Base : auth Bearer. Erreurs : `400` / `403` / `404` / `409` avec `message` FR.
+
+### 1. `DELETE /dossiers/:numeroDossier`
+
+- **Famille** → supprime tous parents + enfants du n° ; clos placements AM des enfants.
+- **AM** → compte AM + dossier AM ; enfants gardés ; placements clos.
+
+**Réponse 200** (exemple) :
+
+```json
+{
+  "type": "famille",
+  "numero_dossier": "2026-000043",
+  "deleted_user_ids": ["…"],
+  "deleted_enfant_ids": ["…"],
+  "message": "Dossier famille supprimé."
+}
+```
+
+ou
+
+```json
+{
+  "type": "assistante_maternelle",
+  "numero_dossier": "2026-000015",
+  "deleted_user_ids": ["…"],
+  "deleted_enfant_ids": [],
+  "message": "Dossier assistante maternelle supprimé."
+}
+```
+
+**Dialog UI** : lister libellé + n° + « X parent(s), Y enfant(s) » (ou « compte AM, enfants conservés »).
+
+---
+
+### 2. `DELETE /users/:id`
+
+Comportement selon le **rôle** de la cible :
+
+| Cible | Effet |
+|-------|--------|
+| Parent **co-parent** | Delete ce user seul |
+| Parent **dernier** du dossier | Delete user + enfants du foyer |
+| AM | Delete user AM + dossier AM ; enfants conservés ; placements clos |
+| Gestionnaire | Admin only ; self → 403 |
+| Administrateur | Self → 403 ; dernier admin → super_admin only sinon 403 ; super_admin → 403 |
+
+**Réponse 200** :
+
+```json
+{
+  "deleted_user_ids": ["…"],
+  "deleted_enfant_ids": ["…"],
+  "message": "…"
+}
+```
+
+**Dialogs** :
+
+- Co-parent : « Ce parent sera retiré / supprimé du dossier {n°}. Les enfants restent avec le co-parent. »
+- Dernier parent : « Dernier parent du dossier {n°}. Les enfants rattachés seront aussi supprimés. »
+- AM : « Le compte et le dossier AM seront supprimés. Les enfants accueillis ne seront pas supprimés. »
+
+Optionnel (si exposé) : `GET /users/:id/suppression-impact` — sinon calculer depuis données déjà en liste / détail dossier.
+
+---
+
+### 3. `DELETE /enfants/:id?deleteDossier=true|false`
+
+- Pas dernier enfant → delete enfant (`deleteDossier` ignoré ou false).
+- Dernier enfant + `deleteDossier=false` → delete enfant ; dossier famille peut passer `sans_enfant`.
+- Dernier enfant + `deleteDossier=true` → cascade dossier famille (parents + enfants).
+
+**Réponse 200** :
+
+```json
+{
+  "deleted_enfant_ids": ["…"],
+  "deleted_user_ids": ["…"],
+  "dossier_supprime": false,
+  "message": "…"
+}
+```
+
+**Dialog** :
+
+- Standard : « L’enfant sera supprimé du dossier de {famille} ({n°}). »
+- Dernier : proposer **deux actions** :
+  1. Supprimer l’enfant seulement (`deleteDossier=false`)
+  2. Supprimer aussi le dossier / parents (`deleteDossier=true`)
+
+Pour savoir si dernier : compter enfants du `numero_dossier` (détail dossier ou champ impact API).
+
+---
+
+### 4. `GET /dossiers` — flag `sans_enfant`
+
+Chaque item famille peut exposer :
+
+```json
+"sans_enfant": true
+```
+
+- `true` si dossier **famille** sans enfant lié.
+- AM : `false` ou omis.
+
+**UI** : badge / warning vigilance (comme `sans_responsable` / alertes AM).
