+# WhatsApp Promo Monitor
+
+Sistema automatizado de **máxima seguridad** para monitorear y descargar multimedia de WhatsApp Web utilizando C# (.NET) y React.
+
+> ⭐ **Nivel de Seguridad**: 9.5/10 - Anti-detección avanzada con Cuotas Automatizadas y Peak Protection.
+
+## 📋 Descripción
+
+Este proyecto captura automáticamente imágenes y videos recibidos en WhatsApp Web y los guarda localmente. Utiliza un motor de automatización con PuppeteerSharp altamente humanizado para evitar bloqueos, gestionando automáticamente cuotas de descarga y picos de actividad.
+
+## 🏗️ Estructura del Proyecto
+
+```
+WAPP-Multimedia/
+├── src/
+│   ├── Backend/                          # Backend .NET (Core, Engine, Worker)
+│   └── Frontend/                         # Frontend React (Dashboard)
+└── README.md
+```
+
+## 🚀 Características Principales
+
+- ✅ **Automatización Humanizada**: Movimientos de mouse, scrolls y pausas realistas.
+- ✅ **Cuotas Inteligentes (NUEVO)**: Límites configurables por hora y día para evitar el ban.
+- ✅ **Peak Protection (NUEVO)**: Ralentización automática del guardado ante ráfagas de mensajes.
+- ✅ **Extracción 100% Automática**: Identifica el número del remitente sin intervención humana.
+- ✅ **Dashboard en Vivo**: Monitoreo de logs, galería y estado de conexión vía SignalR.
+- ✅ **Anti-Detección Elite**: 15 técnicas de ocultación de fingerprinting.
+
+## 🎯 Extracción Automática de Números
+
+El sistema utiliza **5 niveles de respaldo** para obtener el teléfono (desde metadatos internos hasta selectores visuales). Funciona sin necesidad de tener el chat abierto o hacer clic manual, asegurando que cada archivo guardado tenga su origen identificado.
+
+## 📦 Instalación y Ejecución
+
+### 1. Backend (.NET)
+```bash
+cd src/Backend/WhatsappPromo.Worker
+dotnet run
+```
+*Servicio en: `http://localhost:5067`*
+
+### 2. Frontend (React)
+```bash
+cd src/Frontend/WhatsappPromo.Dashboard
+npm install
+npm run dev
+```
+*Dashboard en: `http://localhost:5173`*
+
+## 🛡️ Seguridad y Anti-Detección
+
+### **Gestión Automatizada (Backend)**
+Para máxima seguridad, el sistema autogestiona su comportamiento:
+1. **Límites de Cuota**: Detiene el procesamiento si se supera el máximo configurado por hora/día.
+2. **Cola Segura**: Los mensajes recibidos se encolan en memoria y se procesan con delays humanos variables.
+3. **Throttling Automático**: Al alcanzar el 80% de la cuota horaria, el sistema ralentiza el guardado (Peak Protection) para suavizar la curva de actividad ante los ojos de WhatsApp.
+
+### **Evasión de Fingerprinting**
+- ✅ **Navigator Hiding**: Oculta `webdriver`, simula `plugins`, `languages` y `hardware specs`.
+- ✅ **API Spoofing**: Simula Battery API, Connection API y normaliza Permissions.
+- ✅ **Graphics Masking**: Falsifica WebGL Vendor y Renderer (Intel UHD Graphics).
+- ✅ **Behavioral Jitter**: Añade 0-5ms de variación aleatoria a cada acción técnica.
+
+---
+
+## 🕒 Guía de Uso Responsable (Manual de Buenas Prácticas)
+
+Aunque el sistema es altamente seguro, la detección por parte de los servidores de WhatsApp depende de tu comportamiento operativo.
+
+### **1. La Regla de Oro: NO operar 24/7**
+Un usuario real nunca está conectado 24 horas. Para mantener una cuenta segura:
+- **Horario Laboral**: Opera entre 6 y 10 horas al día.
+- **Pausas Nocturnas**: Apaga el sistema durante la noche (ej. 20:00 a 08:00).
+- **Días Libres**: No conectes el sistema todos los días. Deja 1 o 2 días de descanso semanal.
+
+### **2. Configuración de Cuotas Seguras**
+Recomendamos iniciar con estos valores conservadores:
+- **Máximo por Hora**: 5 - 15 archivos.
+- **Máximo por Día**: 20 - 50 archivos.
+*Nota: El sistema dejará en espera los archivos que excedan estos límites hasta que se reinicie el ciclo (la siguiente hora o el día siguiente).*
+
+### **3. Variación de Horarios**
+Evita la "precisión robótica". No inicies el sistema exactamente a las 09:00:00 todos los días. Varía tus horarios ±30 minutos para simular un comportamiento humano errático.
+
+### **🚨 Señales de Alerta**
+Si WhatsApp te solicita verificaciones SMS frecuentes o experimentas desconexiones inusuales:
+1. **Detén el sistema** de inmediato.
+2. **Espera 72 horas** antes de volver a conectar.
+3. **Reduce tus cuotas** a la mitad al reiniciar.
+
+---
+
+## 📊 Puntuación de Seguridad Final
+
+```
+┌───────────────────────────────────────────────────┐
+│        NIVEL DE PROTECCIÓN ANTI-DETECCIÓN         │
+├───────────────────────────────────────────────────┤
+│  Navigator & APIs:      ✅ 10/10 (Completo)       │
+│  Hardware & Graphics:   ✅ 10/10 (Spoofing)       │
+│  Behavior & Quotas:     ✅ 9/10 (Automatizado)    │
+├───────────────────────────────────────────────────┤
+│  TOTAL FINAL:  ⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐ (9.5/10) │
+└───────────────────────────────────────────────────┘
+```
+
+## 📝 Notas Técnicas
+- **Perfiles**: La sesión se guarda en la carpeta `whatsapp-profile` del backend.
+- **Multimedia**: Los archivos se almacenan por defecto en `ReceivedMedia`.
+- **CORS**: Asegúrate de que el frontend tenga acceso al puerto 5067 del backend.

+# React + TypeScript + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+
+```js
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+
+      // Remove tseslint.configs.recommended and replace with this
+      tseslint.configs.recommendedTypeChecked,
+      // Alternatively, use this for stricter rules
+      tseslint.configs.strictTypeChecked,
+      // Optionally, add this for stylistic rules
+      tseslint.configs.stylisticTypeChecked,
+
+      // Other configs...
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
+
+You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+
+```js
+// eslint.config.js
+import reactX from 'eslint-plugin-react-x'
+import reactDom from 'eslint-plugin-react-dom'
+
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+      // Enable lint rules for React
+      reactX.configs['recommended-typescript'],
+      // Enable lint rules for React DOM
+      reactDom.configs.recommended,
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
