### 11.2 Gaps Identificados

**Funcionalidad con placeholders (para producción):**
1. **Reportes:**
   - Almacenamiento: Map en memoria → Necesita migración a DB + S3
   - Cola de jobs: setTimeout → Necesita Bull/BullMQ

2. **Caché:**
   - Clear cache: Placeholder → Necesita integración con Redis

3. **Sesiones:**
   - Cleanup: Placeholder → Necesita estrategia de storage definida

**Tests pendientes:**
- Tests unitarios: 0 de 7 servicios
- Tests e2e: 0 de 34 endpoints
- **Cobertura de tests:** 0% (PENDIENTE)

---

## 12. Próximos Pasos

### 12.1 Sprint 4 - Cleanup (Estimado 8h)

1. Actualizar frontend `adminAPI.ts` con nuevos endpoints (1h)
2. Crear tests unitarios para servicios críticos (4h)
3. Crear tests e2e para flujos principales (3h)

### 12.2 Mejoras Futuras

1. **Sistema de Reportes Robusto:**
   - Tabla `admin.reports` en DB
   - Almacenamiento en S3 o filesystem
   - Cola de jobs con Bull
   - Más tipos y filtros

2. **Caché Distribuido:**
   - Integración con Redis
   - Cache de dashboard stats (TTL 5min)
   - Invalidación inteligente

3. **WebSockets:**
   - Updates en tiempo real de dashboard
   - Notificaciones de reportes completados
   - Progress de operaciones bulk

4. **Permisos Granulares:**
   - Decorador `@RequiresPermission()`
   - Guards basados en permisos
   - Context-based permissions
