Charger `HeavyStateModule` avec configuration extrême +2. Créer un état massif: + - 1 million de particules (x, y, vx, vy, lifetime, color) + - Matrice de terrain 10000x10000 (100M cellules) + - Historique des 10000 dernières frames + - Cache de 50000 textures simulées +3. État sérialisé estimé: ~120MB en JSON +4. Temps d'initialisation: ~8 secondes + +### Test Séquence + +#### Test 1: Large State Serialization (60s) +1. Exécuter pendant 10 secondes (600 frames) +2. Trigger hot-reload avec extraction de l'état complet +3. Mesurer: + - Temps de `getState()`: doit être < 2000ms + - Taille de l'état sérialisé + - Temps de `setState()`: doit être < 2000ms +4. Vérifier intégrité des données post-reload: + - Nombre de particules = 1M + - Dimensions terrain = 10000x10000 + - Historique complet préservé +5. Continuer pendant 10 secondes supplémentaires + +#### Test 2: Long Initialization Timeout (30s) +1. Charger `HeavyStateModule` avec init duration = 12s +2. Configurer timeout à 10s (volontairement trop court) +3. Vérifier que le système: + - Détecte le timeout correctement + - Annule le chargement proprement + - Libère toutes les ressources + - Log un message d'erreur clair +4. Recharger avec timeout = 15s (suffisant) +5. Vérifier chargement réussi + +#### Test 3: Memory Pressure During Reload (60s) +1. Démarrer avec état 100MB +2. Pendant reload: + - Allouer 200MB supplémentaires (simuler pic mémoire) + - Vérifier que le système ne crash pas (OOM) + - Mesurer temps de reload sous pression +3. Après reload: + - Vérifier retour à 100MB baseline + - Aucune fuite détectée + - État intact + +#### Test 4: Incremental State Save/Load (30s) +1. Activer mode "incremental state" (seuls les deltas) +2. Faire 10 reloads successifs +3. Chaque reload modifie 1% de l'état (10k particules) +4. Mesurer: + - Temps de reload incrémental: doit être < 100ms + - Taille des deltas: doit être ~1MB + - Intégrité finale: 100% des particules correctes + +#### Test 5: State Corruption Detection (20s) +1. Créer un état volontairement corrompu: + - JSON mal formé + - Valeurs hors limites (NaN, Infinity) + - Champs manquants +2. Tenter `setState()` avec état corrompu +3. Vérifier: + - Détection de corruption avant application + - État précédent non affecté + - Message d'erreur descriptif + - Module reste fonctionnel + +--- + +## 🏗️ Implémentation + +### HeavyStateModule Structure + +```cpp +// HeavyStateModule.h +class HeavyStateModule : public IModule { +public: + struct Particle { + float x, y;
