Basado en la auditoría técnica completada el 2025-07-03, se han identificado y resuelto los problemas críticos de despliegue. El sistema está operacional pero requiere optimizaciones para funcionalidad completa.

✅ SOLUCIÓN: Redis URL parsing corregido, backend mínimo operacional
✅ ESTADO: Backend API respondiendo en puerto 8000
✅ ENDPOINTS: /health, /api/v1/utils/health-check/ funcionando

✅ SOLUCIÓN: Nginx configurado con certificados SSL y routing correcto
✅ ESTADO: HTTPS funcionando en puertos 80/443
✅ ENDPOINTS: https://localhost/test verificado

✅ SOLUCIÓN: PostgreSQL + Redis con autenticación funcionando
✅ ESTADO: Tablas creadas, conexiones estables
✅ DATOS: Usuario admin configurado ([email protected])

⚠️ PROBLEMA: SlowAPI rate limiting deshabilitado por conflictos Redis URL
⚠️ IMPACTO: Sin protección contra abuso de API
⚠️ WORKAROUND: Sistema funcionando con middleware comentado
⚠️ SOLUCIÓN: Corregir imports y configuración Redis en SlowAPI

⚠️ PROBLEMA: Solo endpoints básicos activos, funcionalidad limitada
⚠️ IMPACTO: Frontend no puede usar APIs completas
⚠️ ESTADO ACTUAL: Health checks + test endpoints únicamente
⚠️ SOLUCIÓN: Restaurar FastAPI completo sin conflictos de imports

⚠️ PROBLEMA: Nginx no sirve archivos estáticos del frontend correctamente
⚠️ IMPACTO: Algunas rutas frontend pueden no funcionar
⚠️ WORKAROUND: Frontend funciona en puerto 3000 directo
⚠️ SOLUCIÓN: Configurar root directive en nginx.prod.conf

⚠️ PROBLEMA: Sistema funcionando en localhost, no en brain2gain.mx
⚠️ IMPACTO: Acceso público limitado
⚠️ ESTADO: Certificados SSL listos, DNS pendiente
⚠️ SOLUCIÓN: Configurar DNS brain2gain.mx → 5.183.9.128
