El flujo llega **inactive**. No pegues secretos en el lienzo ni en el archivo.\n\n### 2) Credenciales y configuración por nodo\n- **Manual Trigger cold email** (`manual`): sin credencial. Pruebas; en producción → Schedule Trigger leyendo cola Sheets/CRM.\n- **Config Cold Email Escala** (`Set`): **sin credencial**. `campaignName`, `maxEmailsPerDay`, `maxPerInbox`, `requireVerifiedEmail`, `requireHitlBeforeSend`, `crmProvider` + tokens (`REEMPLAZA_*`), `stopOnReply`, `sheetsId`, `slackWebhookUrl`, `batchLabel`, `timezone`.\n- **Payload de prueba (4 leads)** (`Code`): sin credencial. 4 filas @example.com: verified ready, unverified skip, replied_stop, pending_hitl.\n- **Filtrar y rate-limit** (`Code`): sin credencial. Aplica verificación, techo diario y stopOnReply.\n- **IF cola lista**: sin credencial. `queueReady === true`.\n- **Preparar borrador cold email** (`Code`): sin credencial. Genera **solo un borrador**. **No** envía SMTP — el envío real lo haces en Instantly u otro ESP autorizado.\n- **IF requireHitl**: sin credencial.\n- **Slack HITL aprobación** (`HTTP`): Incoming Webhook.\n- **Auto (sin HITL requerido)** (`NoOp`).\n- **Upsert CRM (last_cold_email_at)** (`HTTP`): Header Auth / Bearer según `crmProvider`.\n- **Append Sheets (Cold_Email)**: Google Sheets OAuth2.\n- **Slack resumen cola**: Incoming Webhook.\n\n### 3) Orden de puesta en marcha\n1. Rellena **Config** (`requireVerifiedEmail=true`, `requireHitlBeforeSend=true` recomendado).\n2. Crea Credentials (CRM, Sheets, Slack).\n3. Ejecuta **una vez** con Manual Trigger y revisa las 4 ramas demo.\n4. Revisa Sheets + Slack antes de Active.\n5. En producción: Schedule + cola real; el ESP (Instantly, etc.) aplica sus propios límites y warmup.\n\n### 4) Producción 24/7 en VPS (UE)\n1. VPS UE + Docker Compose + Postgres + HTTPS.\n2. `GENERIC_TIMEZONE=Europe/Madrid`, `WEBHOOK_URL`, `N8N_ENCRYPTION_KEY`.\n3. Firewall 80/443 (+SSH). Backups Postgres + export workflows.\n4. Este flujo **no** envía email masivo: orquesta cola y borradores. Warmup y rotación van en tu ESP.\n5. Alternativa: n8n Cloud.\n\n### 5) RGPD + EU AI Act\nDocumenta interés legítimo B2B, honra bajas/respuestas (`stopOnReply`) y registra skipReason. Si redactas con LLM sois **deployers** (Reglamento UE 2024/1689 Art. 4): HITL obligatorio en primeros lotes. Informativo — no es asesoramiento legal. /uso-responsable-de-ia-y-transparencia\n",
