+# CESIZen - Application de santé mentale
+
+## Contexte du projet
+Projet individuel CESI École d'Ingénieurs — Bloc "Concevoir les solutions logicielles" (INFCDAAL1).
+Commanditaire fictif : Ministère des Solidarités et de la Santé.
+L'objectif est de proposer une plateforme grand public pour accompagner le quotidien de chacun et l'aider à mieux comprendre les enjeux de sa santé mentale et agir sur son stress.
+
+## Module choisi
+**Tracker d'émotions** (module facultatif au choix) + modules obligatoires (Comptes utilisateurs, Informations).
+
+## Architecture technique
+
+### Stack
+- **Backend** : Laravel 11 (PHP 8.2+) — API REST JSON, JWT Auth (`tymon/jwt-auth`)
+- **Frontend Web** : Next.js 16 (React 19, TypeScript, Tailwind CSS 4, Zustand, TanStack Query, Recharts)
+- **Mobile natif** : React Native / Expo 53 (Expo Router, Zustand, SecureStore, TanStack Query)
+- **Base de données** : PostgreSQL 16
+- **Conteneurisation** : Docker Compose (postgres:5432, backend:8000, frontend:3000)
+
+### Design Pattern
+MVC côté backend (Models → Controllers → Routes, Service Layer pour les rapports).
+Frontend : App Router, Custom Hooks, Component Composition, Zustand Store.
+
+### Structure du projet
+```
+Cesizen/
+├── backend/          # Laravel 11 API
+├── frontend/         # Next.js (web)
+├── mobile/           # React Native Expo (iOS + Android)
+├── docker-compose.yml
+└── generate_pdf.py   # Génération du cahier de tests (Python/fpdf)
+```
+
+## Fonctionnalités implémentées
+
+### Modules obligatoires
+- **Comptes utilisateurs** : inscription, connexion JWT, gestion profil, reset password, admin CRUD, désactivation/suppression, RGPD (soft delete + droit à la suppression)
+- **Informations** : pages de contenu santé mentale (feeds), CRUD admin, affichage public
+
+### Module au choix : Tracker d'émotions
+| Fonctionnalité | Acteur | Web | Mobile |
+|---|---|---|---|
+| Afficher le journal de bord | Utilisateur | ✅ | ✅ |
+| Ajouter une saisie (wizard 3 étapes) | Utilisateur | ✅ | ✅ |
+| Modifier une saisie | Utilisateur | ✅ (modale) | ✅ (écran edit) |
+| Supprimer une saisie | Utilisateur | ✅ | ✅ |
+| Rapports par période (semaine/mois/trimestre/année) | Utilisateur | ✅ (graphiques) | ✅ |
+| Configurer les émotions (2 niveaux) | Admin | ✅ | N/A |
+
+### Hiérarchie des émotions (seed)
+7 émotions de base (niveau 1) avec 31 sous-émotions (niveau 2) :
+Joie, Tristesse, Colère, Peur, Dégoût, Surprise, Amour.
+
+## Grille de priorisation des besoins
+Critères utilisés : Complexité (0-3), Valeur ajoutée Ministère (0-3), Valeur ajoutée Utilisateur (0-3), Nécessité (0-2), Interdépendance (0-2). Total sur 15.
+
+Top priorités :
+- Diagnostic de stress / Journal émotions / Rapports d'émotions (10/15)
+- Cryptage données / Inscription / Cohérence cardiaque / Activités détente / Ajout tracker (9/15)
+- Conformité RGPD (8/15)
+
+## Évaluation — Barème (/34 → note lettre)
+| Domaine | Livrable | Pts |
+|---|---|---|
+| Recueil du besoin | Reformulation (contexte, enjeux, contraintes) | 6 |
+| | Identification des besoins logiciels | 3 |
+| | Critères de priorités et pondération | 2 |
+| Analyse des besoins | Complétude du CdC, contraintes, opportunités | 4 |
+| | Réponse fonctionnelle adaptée et originale | 4 |
+| | Schématisation et reformulation visuelle | 2 |
+| Modélisation | MCD (Merise/UML) | 3 |
+| | Conception technique MVC | 2 |
+| | Spécifications fonctionnelles et techniques | 4 |
+| | Données personnelles et sensibles | 1 |
+| Dossier et soutenance | Qualité dossier + oral (20 min + 10 Q/R) | 3 |
+
+Conversion : A (27-34) | B (20-26,99) | C (14-19,99) | D (0-13,99)
+
+## Livrables attendus
+1. **Cahier des charges** (15-20 pages) : contexte, parties prenantes, besoins reformulés, priorisation, contraintes
+2. **Spécifications fonctionnelles et techniques** : UML, analyse détaillée (2 obligatoires + 1 au choix), MCD, MVC, RGPD
+3. **Soutenance orale** : 20 min + 10 min Q/R
+
+## Acteurs du système
+- **Visiteur anonyme** : consultation informations, accès public
+- **Utilisateur connecté** : tracker émotions, journal, rapports, profil
+- **Administrateur** : gestion utilisateurs, contenus, émotions
+
+## Conventions de code
+- Backend : PHP PSR-12, noms en français (utilisateur, saisie_tracker, émotion)
+- Frontend : TypeScript strict, composants fonctionnels, hooks customs
+- Mobile : même conventions que le frontend web
+- Langue de l'interface : français
+- Langue de l'instruction CLAUDE.md globale : toujours répondre en français
+
