+# Mini-spec — Suppression complète grossesse multiple / `est_multiple`
+
+**Ticket** : **#152** — https://git.ptits-pas.fr/jmartin/petitspas/issues/152  
+**Branche** : `feature/152-remove-est-multiple` (depuis `develop`)  
+**Périmètre** : **full stack** — BDD + back + front + scripts + docs. **Aucun fantôme.**
+
+---
+
+## Décision
+
+On **supprime tout**. Pas de DTO « ignorés », pas de compat payload.
+
+`forbidNonWhitelisted: true` ⇒ back et front **partent ensemble** (même feature / même déploiement).
+
+---
+
+## Alias retirés
+
+`est_multiple` · `is_multiple` · `grossesse_multiple` · `multipleBirth` · `estMultiple` · `isMultiple` · `jumeau_multiple`
+
+---
+
+## Back / BDD (fait sur la branche)
+
+- [x] Migration `database/migrations/2026_drop_enfants_est_multiple.sql`
+- [x] `BDD.sql`, seeds, CSV test
+- [x] Entity `Children` sans colonne
+- [x] DTO create/inscription/réponse/dossier famille **sans** le champ
+- [x] Services auth / enfants / parents : plus de mapping
+- [x] Prisma legacy `isMultiple` retiré
+
+## Front (fait sur la branche)
+
+- [x] Modèles admin / dossier / inscription
+- [x] Payloads inscription + reprise
+- [x] Modale enfant + wizard dossier famille
+- [x] Step3 inscription parent
+
+## Scripts / docs
+
+- [x] `tests/scripts/register-parent-*.mjs`
+- [x] `docs/10_DATABASE.md`, `docs/99_REGLES-CODAGE.md`
+- Docs tmp/archive #112 : mentions historiques OK (archive)
+
+---
+
+## Déploiement
+
+1. Appliquer la migration SQL sur la BDD vivante  
+2. Deploy back **et** front de cette branche  
+3. Smoke : création enfant staff, inscription parent, reprise, wizard famille
+
+## Vérif
