-# Changelog - 17 de Febrero 2026
-## Versión 1.7.0 - Corrección Sistema de SLA Dashboard
-
-### 🐛 Bugs Corregidos
-
-#### Error 500 en Endpoint `/api/v1/sla/dashboard`
-
-**Problema Identificado:**
-El endpoint de SLA Dashboard estaba generando errores 500 (Internal Server Error) al intentar cargar las métricas. Se identificaron dos problemas críticos en las queries SQL:
-
-1. **Error de Sintaxis SQL - "missing FROM-clause entry for table 'ticket'"**
-   - **Causa:** Uso incorrecto de `text()` con referencias al modelo SQLAlchemy dentro de expresiones SQL sin formato
-   - **Ubicación:** Cálculo de tickets "at risk" en queries de Response y Resolution SLA
-   - **Expresión problemática:** 
-     ```python
-     text("INTERVAL '20%' * (Ticket.sla_response_due - Ticket.created_at)")
-     ```
-
-2. **Error de Timezone - "can't subtract offset-naive and offset-aware datetimes"**
-   - **Causa:** Comparación entre `datetime.now(timezone.utc)` (timezone-aware) y campos de base de datos `TIMESTAMP WITHOUT TIME ZONE` (timezone-naive)
-   - **Ubicación:** Todas las comparaciones temporales en queries SLA
-
-### ✅ Solución Implementada
-
-#### Archivo Modificado:
-- `backend/app/api/v1/endpoints/sla.py`
-
-#### Cambios Realizados:
-
-1. **Eliminación de SQL Crudo con `text()`**
-   - Se reemplazaron todas las expresiones `text()` con funciones nativas de SQLAlchemy
-   - Se utilizó `func.extract('epoch', ...)` para cálculos temporales seguros
-
-2. **Corrección de Timezone**
-   - Se introdujo `db_now = func.now()` para usar la función `NOW()` de PostgreSQL directamente
-   - `now = datetime.now(timezone.utc)` se mantiene solo para cálculos en Python (ej: `period_start`)
-   - Se reemplazaron todas las comparaciones `now > Ticket.sla_response_due` por `db_now > Ticket.sla_response_due`
-
-3. **Cálculo de Tickets "At Risk" Mejorado**
-   - **Lógica:** Un ticket está "en riesgo" cuando ha consumido más del 80% del tiempo disponible
-   - **Nueva expresión segura:**
-     ```python
-     func.extract('epoch', db_now - Ticket.created_at) > 
-     (func.extract('epoch', Ticket.sla_response_due - Ticket.created_at) * 0.8)
-     ```
-
-#### Secciones del Código Corregidas:
-
-1. **Dashboard Principal** (líneas 93-280)
-   - Query de Response SLA
-   - Query de Resolution SLA
-   - Contadores de violaciones activas
-
-2. **Lista de Violaciones** (líneas 355-395)
-   - Filtro por tipo de SLA (response/resolution)
-   - Queries con timezone corregido
-
-3. **Tickets en Riesgo** (líneas 505-540)
-   - Cálculo del umbral de riesgo
-   - Filtrado de tickets según porcentaje de tiempo consumido
-
-### 🧪 Validación
-
-**Pruebas Realizadas:**
-- ✅ Endpoint `/api/v1/sla/dashboard?days=30` responde correctamente (200 OK)
-- ✅ Backend reiniciado sin errores de sintaxis
-- ✅ Logs del backend sin excepciones de SQLAlchemy
-- ✅ Frontend carga el dashboard de SLA sin errores 500
-
-**Estado del Servicio:**
-```
-servicemanager-backend: Up and healthy
-servicemanager-db: Up and healthy
-servicemanager-redis: Up and healthy
-```
-
-### 📊 Impacto
-
-**Alta Prioridad:** Este fix desbloquea una funcionalidad crítica del sistema de gestión de SLAs, permitiendo a los equipos de soporte visualizar:
-- Métricas de cumplimiento de Response SLA
-- Métricas de cumplimiento de Resolution SLA
-- Tickets en riesgo de violar SLA
-- Violaciones activas
-- Tendencias por categoría y prioridad
-
-### 🔍 Detalles Técnicos
-
-**Stack Tecnológico:**
-- Python 3.11
-- FastAPI (async)
-- SQLAlchemy 2.0 (async ORM)
-- PostgreSQL
-- Docker
-
-**Patrón de Solución:**
-- Uso de funciones SQL nativas a través de SQLAlchemy ORM
-- Separación entre datetime Python (timezone-aware) y SQL timestamps (timezone-naive)
-- Eliminación de strings SQL dinámicos en favor de expresiones type-safe
-
-### 📝 Notas para Desarrollo Futuro
-
-**Lecciones Aprendidas:**
-1. Siempre usar `func.now()` para comparaciones temporales en queries SQL
-2. Evitar `text()` cuando sea posible; preferir funciones SQLAlchemy
-3. Los campos `TIMESTAMP WITHOUT TIME ZONE` en PostgreSQL deben compararse con valores timezone-naive o funciones SQL
-
-**Recomendaciones:**
-- Considerar migración de campos timestamp a `TIMESTAMP WITH TIME ZONE` en futuras versiones
-- Agregar tests de integración para endpoints SLA
-- Implementar monitoreo de queries SQL lentas
