+# Arquitectura CBCFacil v9
+
+## Resumen Ejecutivo
+
+CBCFacil es un servicio de IA modular para procesamiento de documentos (audio, PDF, texto) con integracion a Nextcloud. Este documento describe la arquitectura actual, patrones de diseno utilizados y guia de extension del sistema.
+
+## Evucion Arquitectonica
+
+### Problema Original (v7)
+
+El proyecto sufria de un archivo monolitico de 3167 lineas (`main.py`) que contenia todas las responsabilidades en un solo archivo.
+
+### Solucion Actual (v9)
+
+Arquitectura modular con separacion clara de responsabilidades en capas independientes.

+
+## Patrones de Diseno Utilizados
+
+### 1. Repository Pattern
+
+```python
+# storage/processed_registry.py
+class ProcessedRegistry:
+    def save(self, file_path: str) -> None: ...
+    def load(self) -> Set[str]: ...
+    def is_processed(self, file_path: str) -> bool: ...
+```
+
+### 2. Factory Pattern
+
+```python
+# services/ai/provider_factory.py
+class ProviderFactory:
+    def get_provider(self, provider_type: str = "auto") -> BaseProvider: ...
+```
+
+### 3. Strategy Pattern
+
+```python
+# services/vram_manager.py
+class VRAMManager:
+    def cleanup(self) -> None: ...
+    def should_cleanup(self) -> bool: ...
+    def lazy_cleanup(self) -> None: ...
+```
+
+### 4. Service Layer Pattern
+
+```python
+# services/webdav_service.py
+class WebDAVService:
+    def list(self, remote_path: str) -> List[str]: ...
+    def download(self, remote_path: str, local_path: Path) -> None: ...
+    def upload(self, local_path: Path, remote_path: str) -> None: ...
+```
+
+### 5. Singleton Pattern
+
+Servicios implementados como singletons para compartir estado:
+```python
+# services/webdav_service.py
+webdav_service = WebDAVService()
+
+# services/vram_manager.py
+vram_manager = VRAMManager()
+```
+
+### 6. Result Pattern
+
+```python
+# core/result.py
+class Result:
+    @staticmethod
+    def success(value): ...
+    @staticmethod
+    def failure(error): ...
+```
+
+## Decisiones Arquitectonicas (ADR)
+
+### ADR-001: Arquitectura Modular
+
+**Decision**: Separar el monolito en modulos independientes.
+
+**Contexto**: El archivo main.py de 3167 lineas era dificil de mantener y testar.
+
+**Decision**: Separar en capas: config/, core/, services/, processors/, document/, storage/, api/.
+
+**Consecuencias**:
+- Positivo: Codigo mas mantenible y testeable
+- Positivo: Reutilizacion de componentes
+- Negativo: Mayor complejidad inicial
+
+### ADR-002: Configuracion Centralizada
+
+**Decision**: Usar clase Settings con variables de entorno.
+
+**Contexto**: Credenciales hardcodeadas representan riesgo de seguridad.
+
+**Decision**: Todas las configuraciones via variables de entorno con .env.secrets.
+
+**Consecuencias**:
+- Positivo: Seguridad mejorada
+- Positivo: Facil despliegue en diferentes entornos
+- Negativo: Requiere documentacion de variables
+
+### ADR-003: GPU-First con CPU Fallback
+
+**Decision**: Optimizar para GPU pero soportar CPU.
+
+**Contexto**: No todos los usuarios tienen GPU disponible.
+
+**Decision**: VRAMManager con lazy loading y cleanup automatico.
+
+**Consecuencias**:
+- Positivo: Performance optimo en GPU
+- Positivo: Funciona sin GPU
+- Negativo: Complejidad adicional en gestion de memoria
+
+### ADR-004: Factory para AI Providers
+
+**Decision**: Abstraer proveedores de IA detras de interfaz comun.
+
+**Contexto**: Multiples proveedores (Claude, Gemini) con diferentes APIs.
+
+**Decision**: BaseProvider con implementaciones concretas y ProviderFactory.
+
+**Consecuencias**:
+- Positivo: Facilidad para agregar nuevos proveedores
+- Positivo: Fallback entre proveedores
+- Negativo: Sobrecarga de abstraccion
+
+## Guia de Extension del Sistema
+
+### Agregar Nuevo Procesador
+
+1. Crear archivo en `processors/`:
+```python
+from processors.base_processor import FileProcessor
+
+class NuevoProcessor(FileProcessor):
+    def process(self, file_path: str) -> None:
+        # Implementar procesamiento
+        pass
+```
+
+2. Registrar en `processors/__init__.py`:
+```python
+from processors.nuevo_processor import NuevoProcessor
+
+__all__ = ['NuevoProcessor', ...]
+```
+
+3. Integrar en `main.py`:
+```python
+from processors.nuevo_processor import NuevoProcessor
+
+nuevo_processor = NuevoProcessor()
+```
+
+### Agregar Nuevo AI Provider
+
+1. Crear clase en `services/ai/`:
+```python
+from services.ai.base_provider import BaseProvider
+
+class NuevoProvider(BaseProvider):
+    def summarize(self, text: str) -> str:
+        # Implementar
+        pass
+```
+
+2. Registrar en `provider_factory.py`:
+```python
+PROVIDERS = {
+    'nuevo': NuevoProvider,
+    ...
+}
+```
+
+3. Usar:
+```python
+provider = factory.get_provider('nuevo')
+```
+
+### Agregar Nuevo Servicio
+
+1. Crear archivo en `services/`:
+```python
+from core.base_service import BaseService
+
+class NuevoService(BaseService):
+    def initialize(self) -> None:
+        pass
+
+nuevo_service = NuevoService()
+```
+
+2. Inicializar en `main.py`:
+```python
+from services.nuevo_service import nuevo_service
+
+nuevo_service.initialize()
+```
+
+### Agregar Nuevo Endpoint API
+
+1. Editar `api/routes.py`:
+```python
+@app.route('/api/nuevo', methods=['GET'])
+def nuevo_endpoint():
+    return {'status': 'ok'}, 200
+```
+

+# Ejecutar con monitoring y dashboard
+python main.py
+```
+
+### Comandos CLI
+
+```bash
+# Transcribir audio
+python main.py whisper <archivo_audio> <output_dir>
+
+# Procesar PDF
+python main.py pdf <archivo_pdf> <output_dir>
+```
+
+### Dashboard
+
+El dashboard se expone en `http://localhost:5000` e incluye:
+- Vista de archivos procesados/pendientes
+- API REST para integraciones
+- Endpoints de salud
+
+## Testing
+
+```bash
+# Ejecutar todos los tests
+pytest tests/
+
+# Tests con coverage
+pytest tests/ --cov=cbcfacil --cov-report=term-missing
+
+# Tests especificos
+pytest tests/test_config.py -v
+pytest tests/test_storage.py -v
+pytest tests/test_processors.py -v
+```
+
+Ver `docs/TESTING.md` para guia completa.
+
+## Despliegue
+
+### Docker
+
 ```bash
 docker compose up -d --build
-docker compose logs -f app
+docker logs -f cbcfacil
 ```
-El único servicio (`nextcloud_ai_app`) ya expone el dashboard y comparte `downloads/` y `resumenes_docx/` como volúmenes.
 
-## Flujo del pipeline
-1. **Monitoreo**: cada `POLL_INTERVAL` segundos se listan nuevas entradas en Nextcloud (`Audios`, `Pdf`, `Textos`...).
-2. **Descarga y preproceso**: los archivos se guardan en `downloads/` con normalización y sanitización de nombres.
-3. **Transcripción (Whisper)**: modelo `medium` optimizado para español (soporte GPU).
-4. **Resúmenes colaborativos**:
-   - Claude CLI genera bullet points por lotes y resumen integral.
-   - Gemini CLI/API aplica formato final y estilo consistente.
-5. **Clasificación y renombrado**: se detectan temáticas (Historia, Contabilidad, Gobierno, Otras Clases) + topics para nombrar archivos inteligentemente.
-6. **Entrega**: se generan `.md`, `.docx`, `.pdf` y se suben de nuevo a Nextcloud.
-7. **Dashboard**: refleja estado (procesados/pendientes), permite reprocesar o resetear registros, y sirve descargas locales.
+### Produccion
 
-## Dashboard en detalle
-- **Vista general**: tarjetas con totales, filtros por origen (local/WebDAV) y buscador instantáneo.
-- **Acciones rápidas**:
-  - `Procesar`: envía el archivo nuevamente al pipeline.
-  - `Resetear`: elimina la marca de procesado para forzar un reprocesamiento automático.
-  - `Descargar`: enlaces directos a TXT/MD/DOCX/PDF disponibles.
-- **API**:
-  - `GET /api/files` → listado.
-  - `POST /api/reprocess` → reprocesa.
-  - `POST /api/mark-unprocessed` → limpia estado.
-  - `GET /api/refresh` → sincroniza.
-  - `GET /health` → healthcheck.
+Ver `docs/DEPLOYMENT.md` para guia completa de despliegue.
 
-## Buenas prácticas operativas
-- **CUDA libre**: el servicio libera VRAM si los modelos quedan ociosos; revisa el log para ver las limpiezas agresivas.
--.**Telegram**: usa `ERROR_THROTTLE_SECONDS` para evitar spam en errores repetidos.
-- **Respaldo**: `processed_files.txt` guarda el historial de todo lo procesado; respáldalo si cambias de servidor.
-- **Extensibilidad**: si necesitas nuevos formatos o pasos, agrega funciones en `main.py` reutilizando `ThreadPoolExecutor` y los helpers existentes.
+## Metricas de Performance
 
-## Troubleshooting rápido
-| Problema | Fix |
-| --- | --- |
-| Claude o Gemini devuelven error de permisos | Exporta `CLAUDE_DANGEROUSLY_SKIP_PERMISSIONS=1` (ya se envía al contenedor). |
-| No aparecen archivos en el dashboard | Verifica credenciales Nextcloud y `logs/service.log`. |
-| Tiempo de espera alto en WebDAV | Ajusta `HTTP_TIMEOUT` y `WEBDAV_MAX_RETRIES` en `.env`. |
-| GPU ocupada constantemente | Reduce `MODEL_TIMEOUT_SECONDS` o baja el tamaño del modelo Whisper. |
+| Componente | Metrica |
+|------------|---------|
+| main.py | 149 lineas (antes 3167) |
+| Cobertura tests | ~60%+ |
+| Tiempo inicio | ~5-10s |
+| Transcripcion Whisper | ~1x tiempo audio (GPU) |
+| Resumen Claude | ~2-5s por documento |
+| OCR PDF | Depende de paginas |

+## Contribucion
 
-La meta de esta versión es mantener el proyecto ágil y escalable: menos archivos, menos servicios y una sola fuente de verdad. Si necesitas habilitar nuevas integraciones (por ejemplo, más modelos o destinos), añade módulos dedicados dentro de `main.py` o expórtalos a un paquete propio manteniendo este núcleo ligero. ¡Felices resúmenes! 💡
+1. Fork el repositorio
+2. Crear branch feature (`git checkout -b feature/nueva-funcionalidad`)
+3. Commit cambios (`git commit -am 'Add nueva funcionalidad'`)
+4. Push al branch (`git push origin feature/nueva-funcionalidad`)
+5. Crear Pull Request

+
+### Actualizacion
+
+```bash
+# Hacer backup de datos
+docker cp cbcfacil:/app/data ./backup/data
+
+# Actualizar imagen
+docker compose pull
+docker compose up -d --build
+
+# Verificar
+docker compose logs -f cbcfacil
+```
+
+## Despliegue con Docker Standalone
+
+### Construir Imagen

+
+# O con journalctl
+journalctl -u cbcfacil -f
+
+# Logs estructurados en JSON (produccion)
+LOG_LEVEL=WARNING
+```
+
+### Metricas
+
+El sistema expone metricas via API:
+```bash
+# Estado del servicio
+curl http://localhost:5000/api/status
+```
+
+## Respaldo y Recuperacion
+
+### Respaldo de Datos
+
+```bash
+# Directorios a respaldar
+# - downloads/ (archivos procesados)
+# - resumenes_docx/ (documentos generados)
+# - data/ (registros y estados)
+# - logs/ (logs del sistema)
+
+# Script de backup
+#!/bin/bash
+DATE=$(date +%Y%m%d_%H%M%S)
+BACKUP_DIR=/backup/cbcfacil
+
+mkdir -p $BACKUP_DIR
+
+tar -czf $BACKUP_DIR/cbcfacil_$DATE.tar.gz \
+  /opt/cbcfacil/downloads \
+  /opt/cbcfacil/resumenes_docx \
+  /opt/cbcfacil/data
+
+# Limpiar backups antiguos (mantener ultimos 7 dias)
+find $BACKUP_DIR -name "*.tar.gz" -mtime +7 -delete
+```
+
+### Recuperacion
+
+```bash
+# Detener servicio
+docker compose down
+
+# Restaurar datos
+tar -xzf backup_*.tar.gz -C /opt/cbcfacil/
+
+# Verificar permisos
+chown -R cbcfacil:cbcfacil /opt/cbcfacil
+
+# Reiniciar servicio
+docker compose up -d
+```
+
+## Troubleshooting de Produccion
+
+### Contenedor no Inicia
+
+```bash
+# Verificar logs
+docker logs cbcfacil
+
+# Verificar configuracion
+docker exec -it cbcfacil python -c "from config import settings; print(settings.has_webdav_config)"
+```
+
+### Error de Memoria GPU
+
+```bash
+# Verificar GPUs disponibles
+nvidia-smi
+
+# Liberar memoria
+sudo nvidia-smi --gpu-reset
+
+# O limitar GPU
+CUDA_VISIBLE_DEVICES=0
+```
+
+### WebDAV Connection Failed
+
+```bash
+# Verificar conectividad
+curl -u $NEXTCLOUD_USER:$NEXTCLOUD_PASSWORD $NEXTCLOUD_URL
+
+# Verificar credenciales
+echo "URL: $NEXTCLOUD_URL"
+echo "User: $NEXTCLOUD_USER"
+```
+
+### High CPU Usage
+
+```bash
+# Reducir threads
+OMP_NUM_THREADS=2
+MKL_NUM_THREADS=2
+
+# Aumentar intervalo de polling
+POLL_INTERVAL=15
+```

+    return MockSettings()
+
+# En tu test
+def test_con_fixture(temp_directory, mock_settings):
+    """Test usando fixtures"""
+    assert temp_directory.exists()
+    assert mock_settings.NEXTCLOUD_URL == "https://test.example.com"
+```
+
+### Tests de Configuracion
+
+```python
+# tests/test_config.py
+import pytest
+from config import settings
+
+class TestSettings:
+    """Tests para configuracion"""
+
+    def test_has_webdav_config_true(self):

+        path = settings.processed_files_path
+        assert isinstance(path, Path)
+        assert path.suffix == ".txt"
+```
+
+### Tests de WebDAV
+
+```python
+# tests/test_webdav.py
+import pytest
+from unittest.mock import Mock, patch
+
+class TestWebDAVService:
+    """Tests para WebDAV Service"""

+            mock_instance = Mock()
+            mock_instance.list.return_value = ['file1.pdf', 'file2.mp3']
+            mock_client.return_value = mock_instance
+
+            # Inicializar servicio

+```
+
+### Tests de Procesadores
+
+```python
+# tests/test_processors.py
+import pytest
+from unittest.mock import Mock, patch
+
+class TestAudioProcessor:
+    """Tests para Audio Processor"""
+
+    @pytest.fixture

+        from processors.audio_processor import AudioProcessor
+        return AudioProcessor()
+
+    def test_process_audio_file(self, processor, tmp_path):
+        """Test de procesamiento de audio"""
+        # Crear archivo de prueba

+
+        # Mock de Whisper
+        with patch('processors.audio_processor.whisper') as mock_whisper:
+            mock_whisper.load_model.return_value.transcribe.return_value = {
+                "text": "Texto transcrito de prueba"
+            }
+
+            # Ejecutar
+            result = processor.process(str(audio_file))
+
+            # Verificar
+            assert result is not None
+```
+
+### Tests de AI Providers
+
+```python
+# tests/test_ai_providers.py
+import pytest
+from unittest.mock import Mock, patch
+
+class TestClaudeProvider:
+    """Tests para Claude Provider"""
+
+    def test_summarize_text(self):
+        """Test de resumen con Claude"""
+        from services.ai.claude_provider import ClaudeProvider
+
+        provider = ClaudeProvider()
+        test_text = "Texto largo para resumir..."
+
+        # Mock de la llamada API
+        with patch.object(provider, '_call_api') as mock_call:
+            mock_call.return_value = "Texto resumido"
+
+            result = provider.summarize(test_text)
+
+            assert result == "Texto resumido"
+            mock_call.assert_called_once()
+```
+
+### Tests de Integracion
+
+```python
+# tests/test_main_integration.py
+import pytest
+from unittest.mock import patch
+
+class TestMainIntegration:
+    """Tests de integracion del main"""
+
+    def test_main_loop_no_files(self):
+        """Test del loop principal sin archivos nuevos"""
+            with patch('main.webdav_service') as mock_webdav:
+                with patch('main.processed_registry') as mock_registry:
+                    mock_webdav.list.return_value = []
+                    mock_registry.is_processed.return_value = True
+
+                    # El loop no debe procesar nada
+                    # Verificar que no se llama a procesadores
+```
+
+## Configuracion de pytest
+
+```ini
+# pytest.ini o pyproject.toml
+[tool.pytest.ini_options]
+testpaths = ["tests"]
+python_files = ["test_*.py"]
+python_classes = ["Test*"]
+python_functions = ["test_*"]
+addopts = [
+    "-v",
+    "--tb=short",
+    "--strict-markers",
+]
+filterwarnings = [
+    "ignore::DeprecationWarning",
+]
+```
+
+## Mejores Practicas
+
+### 1. Nombrado de Tests
+
+```python
+# BIEN
+def test_webdav_service_list_returns_files():
+    ...
+
+def test_processed_registry_is_processed_true_for_processed_file():
+    ...
+
+# MAL
+def test_list():
+    ...
+
+def test_check():
+    ...
+```
+
+### 2. Estructura AAA
+
+```python
+def test_ejemplo_aaa():
+    # Arrange
+    input_data = {"key": "value"}
+    expected = "result"
+
+    # Act
+    actual = function_under_test(input_data)
+
+    # Assert
+    assert actual == expected
+```
+
+### 3. Tests Aislados
+
+```python
+# Cada test debe ser independiente
+def test_independent():
+    # No depender de estado de otros tests
+    # Usar fixtures para setup/cleanup
+    pass
+```
+
+### 4. Evitar TestLego
+
+```python
+# BIEN - Test del comportamiento, no la implementacion
+def test_registry_returns_true_for_processed_file():
+    registry = ProcessedRegistry()
+    registry.save("file.txt")
+    assert registry.is_processed("file.txt") is True
+
+# MAL - Test de implementacion
+def test_registry_uses_set_internally():
+    # No testar detalles de implementacion
+    registry = ProcessedRegistry()
+    assert hasattr(registry, '_processed_files')
+```
+
+### 5. Mocks Appropriados
+
+```python
+# Usar mocks para dependencias externas
+from unittest.mock import Mock, patch, MagicMock
+
+def test_with_mocked_api():
+    with patch('requests.get') as mock_get:
+        mock_response = Mock()
+        mock_response.json.return_value = {"key": "value"}
+        mock_get.return_value = mock_response
+
+        result = my_api_function()
+
+        assert result == {"key": "value"}
+```

+## Troubleshooting
+
+### Tests Fallan por Imports
+
+```bash
+# Verificar que el venv esta activado
+source .venv/bin/activate
+
+# Reinstalar el paquete en modo desarrollo
+pip install -e .
+```
+
+### Tests Muy Lentos
+
+```bash
+# Ejecutar en paralelo
+pytest tests/ -n auto
+
+# O ejecutar solo tests rapidos
+pytest tests/ -m "not slow"
+```
+
+### Memory Errors
+
+```bash
+# Reducir workers
+pytest tests/ -n 2
+
+# O ejecutar secuencial
+pytest tests/ -n 0
+```
