+- **Machines** : création, édition, vue détaillée avec structure hiérarchique (composants, pièces, produits)
+- **Squelettes machines** : templates réutilisables pour créer des machines à partir d'un modèle type
+- **Sites** : gestion multi-sites avec coordonnées de contact
+
+### Catalogues
+
+- **Composants**, **Pièces**, **Produits** : catalogues avec recherche serveur, tri, pagination et filtres
+- **Catégories** : système de types avec champs personnalisés configurables et exigences (contraintes de structure)
+- **Fournisseurs** : gestion des constructeurs/fabricants avec liaison multi-entités
+
+### Documents et traçabilité
+
+- **Documents** : upload, prévisualisation PDF/images, stockage sur système de fichiers avec compression PDF automatique

+
+## Conventions de code
+
+### Composables
+
+Pattern avec injection de dépendances explicite :
+
+```typescript
+interface Deps {
+  machineId: Ref<string>
+  onSave: () => void
+}
+
+export function useMachineDetail(deps: Deps) {
+  // ...
+}
+```
+
+### Communication entre composants
+
+**Props + Events uniquement** — pas de `provide/inject` dans le projet.
+
+### Appels API
+
+Le composable `useApi.ts` centralise tous les appels HTTP :
+- Cookies de session inclus automatiquement (`credentials: 'include'`)
+- `application/ld+json` pour POST/PUT
+- `application/merge-patch+json` pour PATCH
+- Gestion d'erreurs centralisée avec traduction des messages backend en français
+
+### Styles
+
+Classes DaisyUI standard :
+- Input : `input input-bordered input-sm md:input-md`
+- Select : `select select-bordered select-sm md:select-md`
+- Button : `btn btn-sm md:btn-md btn-primary`
+
+## Authentification
+
+L'application utilise une **authentification par session (cookies)**, pas de JWT.
+
+Le middleware global `profile.global.ts` vérifie la session à chaque navigation :
+- Utilisateur non connecté → redirection vers `/profiles`
+- Route `/admin/*` → accès restreint à `ROLE_ADMIN`
+
+## Tests
+
+- **13 tests unitaires** (Vitest + happy-dom) couvrant composables, utils et composants
+- **3 specs E2E** (Playwright + Chrome) avec setup d'authentification
+
+## Submodule Git
+
+Ce repo est un **submodule** du repo principal [Inventory](https://gitea.malio.fr/MALIO-DEV/Inventory).
+
+Workflow de commit :
+1. Commiter dans ce repo (frontend) en premier
+2. Commiter dans le repo principal pour mettre à jour le pointeur submodule
+3. Pousser les deux repos
