El flujo llega **inactive**. No pegues secretos en el lienzo ni en el archivo.\n\n### 2) Credenciales y configuración por nodo\n- **Cada 15 minutos** (`schedule`): sin credencial. Revisa expresión cron / intervalo y zona **Europe/Madrid** (settings del workflow). Solo dispara si n8n está **Active** 24/7.\n- **Config alerta errores** (`Set` Config): **no lleva credencial**. Aquí van URLs/placeholders (`REEMPLAZA_*`, `example.com`, `TU-CRM`). Sustituye todos antes de Active.\n- **GET executions error** (`HTTP Request` API n8n): Credentials → **Header Auth** con API key de n8n (`X-N8N-API-KEY`). URL base = tu instancia (`https://n8n.tudominio.com`).\n- **Contar fallos recientes** (`Set`): sin credencial. Revisa expresiones `={{ }}` y campos de salida.\n- **¿Hay fallos recientes?** (`IF`): sin credencial. Comprueba la condición (email, umbral, over_limit, etc.) con datos reales de prueba.\n- **Alerta Slack (errores)** (`HTTP Request` → Slack/Teams): crea Incoming Webhook en Slack (o Adaptive Card URL en Teams). Pega la URL en **Config** o en este nodo. Auth: none (la URL ya es secreta).\n\n### 3) Orden recomendado de puesta en marcha\n1. Rellena el nodo **Config** (URLs reales, umbrales, webhooks de Slack).\n2. Crea Credentials en n8n (candado de cada nodo HTTP / Sheets / OpenAI) y **enlázalas**.\n3. Ejecuta **una vez** (Manual / Test URL del Webhook / \"Execute workflow\").\n4. Verifica CRM + Slack/Sheets (y que la IA no escriba en producción sin HITL).\n5. Solo entonces: interruptor **Active**.\n\n### 4) Producción 24/7 en VPS (UE)\nImportar en localhost no basta: webhooks y cron necesitan n8n encendido.\n\n1. VPS en UE (Hetzner/OVH/IONOS…) + Docker Compose + **Postgres** + HTTPS (Caddy/Nginx).\n2. Variables mínimas: `GENERIC_TIMEZONE=Europe/Madrid`, `WEBHOOK_URL=https://n8n.tudominio.com/`, `N8N_ENCRYPTION_KEY`, `N8N_HOST` / `N8N_PROTOCOL=https`.\n3. Firewall: solo 80/443 (+ SSH). Backups del volumen Postgres + export de workflows.\n4. Importa este JSON en la instancia de producción, vuelve a crear Credentials (no se copian solas), actualiza URLs del Config al dominio real.\n5. Pon **Active**. Prueba el Webhook de producción o espera el próximo cron.\n6. Alternativa: **n8n Cloud** (mismo JSON; Credentials en la UI Cloud).\n\n### 5) RGPD + EU AI Act (resumen)\nSi hay nodos IA sois **deployers** (Reglamento UE 2024/1689). Art. 4 alfabetización. **HITL** antes de outreach, scores masivos o pausas de cuenta. Minimiza PII en Slack/logs. Informativo — no es asesoramiento legal. /uso-responsable-de-ia-y-transparencia\n",
