+# Naming Convention (Naming Template) — Spécification technique
+
+## Vue d'ensemble
+
+Feature permettant aux administrateurs d'un projet BIMData de définir des **règles de nommage** pour les fichiers déposés dans les dossiers de la GED. Les règles peuvent être appliquées en mode souple (avertissement) ou strict (blocage).
+
+---
+
+## Architecture
+
+```
+src/
+├── composables/
+│   └── useNamingConvention.js        ← Hook principal à brancher dans l'upload
+├── services/
+│   └── namingConventionService.js    ← Logique pure (regex, validation, suggestions)
+├── stores/
+│   └── namingConventionStore.js      ← State Pinia, CRUD règles, check upload
+└── components/naming/
+    ├── NamingConventionPanel.vue     ← Panneau création/édition d'une règle
+    ├── NamingSegmentRow.vue          ← Ligne d'un segment dans le formulaire
+    ├── NamingRulesList.vue           ← Liste des règles + assignation dossier

+    ├── NamingViolationBanner.vue     ← Bannière non-bloquante (mode souple)
+    └── GedFileUpload.integration.vue ← Exemple d'intégration dans la GED
+```
+
+---
+
+## Modèle de données
+
+### NamingRule
+
+```ts
+interface NamingRule {
+  id: string;
+  name: string;                    // "Convention métier projet X"
+  separator: "-" | "." | "_";
+  segments: NamingSegment[];
+  mode: "soft" | "strict";
+  recursive: boolean;              // s'applique aux sous-dossiers
+  folder_ids: string[];            // dossiers cibles
+  pattern: string;                 // ex: "a.1.a" (généré auto)
+  creator_email?: string;
+  created_at: string;
+  updated_at: string;
+  active: boolean;
+}
+```
+
+### NamingSegment
+
+```ts
+type NamingSegment =
+  | { type: "n_chars";  config: { min?: number; max?: number } }
+  | { type: "bounded";  config: { min: number; max: number } }
+  | { type: "list";     config: { listId?: string; values: string[] } }
+```
+
+### CustomList
+
+```ts
+interface CustomList {
+  id: string;
+  name: string;
+  values: string[];    // ["WIP", "VAL", "ARCH", ...]
+}
+```
+
+---
+
+## Règles de validation
+
+Le service `namingConventionService.js` construit un regex depuis la définition d'une règle :
+
+| Segment       | Pattern regex généré         | Exemple          |
+|---------------|------------------------------|------------------|
+| N caractères  | `[\w\-]{min,max}`            | `[\w\-]{2,8}`    |
+| Valeurs bornées | Alternation numérique      | `(1\|2\|...\|50)` |
+| Liste         | Alternation des valeurs      | `(WIP\|VAL\|ARCH)` |
+
+Le séparateur est intercalé entre chaque segment.
+L'extension de fichier (`.ifc`, `.pdf`…) est tolérée en suffixe.
+
+**Exemple** : Règle `a.1.a` avec séparateur `.` :
+- Segments : [N chars, Bounded(1-99), N chars]
+- Regex : `^[\w\-]+\.(1|2|...|99)\.[\w\-]+(\.[a-zA-Z0-9]+)?$`
+- ✅ `20191002.1.Piping.ifc`
+- ❌ `20191002Mechanical Piping.ifc`
+
+---
+
+## Flux d'upload (intégration GED)
+
+```
+User sélectionne fichier(s)
+        ↓
+useNamingConvention.checkBeforeUpload(files)
+        ↓
+store.checkFilesBeforeUpload(files, folder)
+  → récupère les règles effectives du dossier (directes + récursives)
+  → valide chaque fichier contre chaque règle
+        ↓
+    ┌───────────────────────────────┐
+    │  Aucune violation ?           │ → upload immédiat
+    ├───────────────────────────────┤
+    │  Violations soft seulement ?  │ → NamingViolationBanner (non-bloquant)

+## Routes API (à implémenter dans platform-back)
+
+| Méthode | Route | Description |
+|---------|-------|-------------|
+| `GET`   | `/cloud/:cloudPk/project/:projectPk/naming-rules` | Liste des règles |
+| `POST`  | `/cloud/:cloudPk/project/:projectPk/naming-rules` | Créer une règle |
+| `PATCH` | `/cloud/:cloudPk/project/:projectPk/naming-rules/:id` | Modifier une règle |
+| `DELETE`| `/cloud/:cloudPk/project/:projectPk/naming-rules/:id` | Supprimer une règle |
+| `GET`   | `/cloud/:cloudPk/project/:projectPk/naming-lists` | Listes personnalisées |
+| `POST`  | `/cloud/:cloudPk/project/:projectPk/naming-lists` | Créer une liste |
+
+> **Note** : En attendant l'implémentation backend, le store utilise `localStorage` comme stub. Remplacer les blocs commentés `// When platform-back implements this endpoint` par les vrais appels API.
+
+---
+
+## Composants UI — résumé
+
+### `NamingConventionPanel.vue`
+Panneau latéral de création/édition d'une règle.
+- **Étape 1** : Nom de la règle
+- **Étape 2** : Séparateur (tiret / point / underscore)
+- **Étape 3** : Segments (N chars / Borné / Liste) avec aperçu live du pattern
+- **Mode** : checkbox stricte + checkbox récursive
+- Emit : `saved(rule)`, `close`
+
+### `NamingSegmentRow.vue`
+Ligne d'un segment dans le builder. Drag-handle pour réordonner.
+- N chars : inputs min/max
+- Borné : inputs min/max numériques
+- Liste : select parmi les `CustomList` du projet
+
+### `NamingRulesList.vue`
+Panneau latéral listant les règles existantes.
+- Recherche texte
+- Sélection par radio pour assigner au dossier courant
+- Badge "strict" sur les règles en mode strict
+- Bouton édition inline
+- Section d'assignation/désassignation au dossier courant
+
+### `NamingViolationModal.vue`
+Modale **bloquante** (mode strict).
+- Affiche les fichiers non-conformes groupés par règle
+- Champ de renommage inline par fichier
+- Validation live du nouveau nom contre la règle
+- Bouton "Renommer" actif uniquement quand tous les fichiers sont résolus
+
+### `NamingViolationBanner.vue`
+Bannière **non-bloquante** (mode souple).
+- Résumé cliquable avec compteur de violations
+- Liste expandable des fichiers non-conformes
+- Renommage inline optionnel
+- Dismiss pour ignorer
+
+---
+
+## Intégration dans la GED existante
+
+1. **Importer le composable** dans votre composant d'upload GED :
+   ```js
+   import { useNamingConvention } from "@/composables/useNamingConvention.js";
+   const naming = useNamingConvention(() => currentFolder.value);
+   ```
+
+2. **Intercepter les fichiers** avant l'upload :
+   ```js
+   const { files } = await naming.checkBeforeUpload(selectedFiles);
+   await uploadFiles(files); // avec les noms potentiellement renommés
+   ```
+
+3. **Afficher les composants UI** dans le template :
+   ```html
+   <NamingViolationBanner v-if="naming.showBanner.value" ... />
+   <NamingViolationModal  v-if="naming.showModal.value"  ... />
+   ```
+
+4. **Exposer le panneau de gestion** via un bouton "Conventions de nommage" dans la toolbar GED.
+
+5. **Initialiser les règles** au mount :
+   ```js
+   store.fetchRules(cloudPk, projectPk);
+   ```
+
+---
+
+## Tests
+
+Fichier : `src/services/namingConventionService.test.js`
+
+Couverture :
+- `buildRuleRegex` : N chars, borné, liste, extension, règle complexe
+- `validateFileName` : valid / invalid / extension
+- `buildHumanReadablePattern` : tous types de segments
+- `suggestRenames` : génération de suggestions, préservation extension
+- Flow complet soft vs strict (simulation store)
+
+Run : `npx jest src/services/namingConventionService.test.js`
