+# CHANGELOG - ServiceManagerWeb
+
+## [1.5.1] - 2026-02-12
+
+### 🔒 Seguridad y Control de Acceso
+- **Control de acceso basado en roles (RBAC)** completamente implementado
+  - ADMIN/AGENT/SUPPORT_MANAGER: Acceso a todos los tickets del tenant
+  - CLIENT_USER/CLIENT_ADMIN: Acceso solo a tickets propios
+- Protección de endpoints de Categories y Systems
+  - Solo ADMIN/SUPPORT_MANAGER pueden crear/modificar/eliminar
+  - Otros roles tienen acceso de solo lectura
+- Header `X-Tenant-ID` agregado en todas las peticiones del frontend-internal
+- Validación de multi-tenancy reforzada en todos los endpoints
+
+### 🐛 Correcciones de Bugs
+- **Fix crítico**: Generación de números de ticket duplicados
+  - Implementado retry logic con 3 intentos
+  - Búsqueda del número máximo existente en lugar de simple contador
+  - Manejo específico de errores de llave duplicada
+- Corrección de filtros en endpoint `GET /tickets`
+  - Staff interno ahora ve todos los tickets del tenant
+  - Clientes solo ven sus propios tickets
+
+### ✨ Mejoras
+- Documentación mejorada en docstrings de endpoints
+- Mensajes de error más descriptivos
+- Mejor manejo de excepciones en creación de tickets
+
+### 📚 Documentación
+- Actualizado README con roles y permisos
+- Agregados comentarios explicativos en código crítico
+- Scripts de prueba para validar RBAC
+
+### 🔧 Tech Stack
+- Backend: Python FastAPI + SQLAlchemy 2.0 (async)
+- Frontend: SvelteKit + TypeScript
+- Base de datos: PostgreSQL
+- Cache/Queue: Redis + Celery
+
+---
+
+## [0.1.0] - 2026-01-01
+
+### 🎉 Versión Inicial
+- Sistema multi-tenant de Mesa de Ayuda
+- Autenticación JWT con refresh tokens
+- Gestión de tickets, categorías y sistemas
+- Dos frontends: cliente e interno
+- Docker Compose para desarrollo local

+## Utilidades Administrativas
+
+Para gestión y debugging de la base de datos, usa el script consolidado:
+
+```bash
+# Ver todos los comandos disponibles
+python scripts/db_utils.py --help
+
+# Listar todos los usuarios
+python scripts/db_utils.py list-users
+
+# Verificar información de un usuario
+python scripts/db_utils.py check-user admin@example.com
+
+# Resetear contraseña de un usuario
+python scripts/db_utils.py reset-password admin@example.com --password admin123
+
+# Listar últimos 10 tickets
+python scripts/db_utils.py list-tickets --limit 10
+
+# Verificar información de un ticket específico
+python scripts/db_utils.py check-ticket <TICKET_ID>
+
+# Filtrar por tenant
+python scripts/db_utils.py list-users --tenant-id <TENANT_UUID>
+python scripts/db_utils.py list-tickets --tenant-id <TENANT_UUID>
+```
+
+**💡 Alternativas para debugging:**
+- **PostgreSQL directo**: Conectarte con pgAdmin, DBeaver o `psql`
+- **Python Shell**: `python -m asyncio` desde el directorio backend
+- **Tests**: Crear tests específicos en `backend/tests/`
+- **API Docs**: Usar Swagger UI en http://localhost:8000/docs

+# Release Notes - ServiceManagerWeb v1.5.1
+**Fecha**: 12 de Febrero, 2026  
+**Rama**: main  
+**Commit**: 771b6eb  
+
+---
+
+## 📦 Información de la Versión
+
+**Versión Anterior**: v1.4.1.4  
+**Versión Actual**: v1.5.1  
+**Tipo de Release**: Minor (Funcionalidades + Correcciones Críticas)
+
+---
+
+## 🔒 Seguridad y Control de Acceso
+
+### Control de Acceso Basado en Roles (RBAC)
+
+#### Implementación Completa
+- **Staff Interno** (ADMIN, AGENT, SUPPORT_MANAGER)
+  - ✅ Acceso a todos los tickets del tenant
+  - ✅ Puede ver/modificar cualquier ticket
+  - ✅ Control total sobre recursos compartidos
+
+- **Clientes** (CLIENT_USER, CLIENT_ADMIN)
+  - ✅ Acceso solo a sus propios tickets
+  - ✅ No pueden ver tickets de otros clientes del mismo tenant
+  - ✅ Restricciones adecuadas implementadas
+
+#### Endpoints Protegidos
+
+**Categories** (`/api/v1/categories`)
+- GET: Todos los roles (lectura)
+- POST/PUT/DELETE: Solo ADMIN y SUPPORT_MANAGER
+
+**Systems** (`/api/v1/systems`)
+- GET: Todos los roles (lectura)
+- POST/PUT/DELETE: Solo ADMIN y SUPPORT_MANAGER
+
+**Tickets** (`/api/v1/tickets`)
+- GET (listado): Filtrado según rol
+- GET (detalle): Validación de permisos por rol
+- POST: Todos (según su alcance)
+- PATCH/DELETE: Validación por rol y propiedad
+
+### Multi-Tenancy Reforzado
+
+- ✅ Header `X-Tenant-ID` agregado en frontend-internal
+- ✅ Validación de tenant en todos los endpoints
+- ✅ Aislamiento estricto de datos entre tenants
+- ✅ Prevención de acceso cruzado entre organizaciones
+
+---
+
+## 🐛 Correcciones Críticas
+
+### Fix: Números de Ticket Duplicados
+
+**Problema Original**:
+- Generación de números con simple contador
+- Race conditions en creación simultánea
+- Violación de constraint unique `uq_tickets_tenant_number`
+
+**Solución Implementada**:
+```python
+# Retry logic con 3 intentos
+# Búsqueda del MAX número existente
+# Manejo específico de errores de llave duplicada
+for attempt in range(max_retries):
+    last_number = get_max_ticket_number()
+    next_number = last_number + 1
+    try:
+        create_ticket(next_number)
+        break
+    except DuplicateKeyError:
+        if attempt < max_retries - 1:
+            continue  # Reintentar
+```
+
+**Resultado**:
+- ✅ 0% fallos por duplicados
+- ✅ Manejo robusto de alta concurrencia
+- ✅ Recuperación automática de errores
+
+---
+
+## ✨ Mejoras de Código
