+## 🧪 Tests et Monitoring
+
+### Tests unitaires
+```bash
+# Tests complets
+npm test
+
+# Tests en mode watch
+npm run test:watch
+
+# Couverture de code
+npm run test:coverage
+```
+
+### Tests d'intégration

+
+# Métriques de performance
+npm run metrics
+```
+
+## 🔄 Compatibilité WASM
+
+### Stub WASM sdk_client
+Le projet utilise un stub WASM temporaire pour `sdk_client` :
+
+```typescript
+import { create_device, create_process } from 'sdk_client';
+
+// Utilisation du stub
+const device = create_device("device_123");
+const process = create_process("process_456", device);
+```
+
+### Structure du stub
+```
+pkg/
+├── sdk_client.js      # Implémentation JavaScript
+├── sdk_client.d.ts    # Types TypeScript
+├── sdk_client_bg.wasm # Fichier WASM minimal
+└── package.json       # Manifeste npm
+```
+
+### Migration vers WASM natif
+- 🔄 **Phase 1** : Stub temporaire (✅ Terminé)
+- ⏳ **Phase 2** : Migration complète WASM (planifié)
+- ⏳ **Phase 3** : Optimisations de performance (planifié)
+
