+# Configuración Avanzada de GitHub Copilot para ServiceManagerWeb
+
+## Variables de Contexto Importantes
+
+### Configuración del Sistema
+```env
+# Variables críticas a considerar
+DATABASE_URL=postgresql+asyncpg://user:pass@localhost:5432/servicemanager
+REDIS_URL=redis://localhost:6379/0
+JWT_SECRET_KEY=your-secret-key
+TENANT_ISOLATION=strict
+CORS_ORIGINS=["http://localhost:3000", "http://localhost:3001"]
+```
+
+### Modelos de Datos Clave
+
+#### User Model Completo
+```python
+class User(Base):
+    __tablename__ = "users"
+    
+    id: Mapped[int] = mapped_column(primary_key=True)
+    tenant_id: Mapped[int] = mapped_column(ForeignKey("tenants.id"))
+    email: Mapped[str] = mapped_column(unique=True, index=True)
+    role: Mapped[UserRole] = mapped_column(default=UserRole.CLIENT_USER)
+    is_active: Mapped[bool] = mapped_column(default=True)
+    created_at: Mapped[datetime] = mapped_column(default=datetime.utcnow)
+```
+
+#### Ticket Workflow States
+```python
+class TicketStatus(str, Enum):
+    OPEN = "open"
+    IN_PROGRESS = "in_progress" 
+    PENDING_CLIENT = "pending_client"
+    RESOLVED = "resolved"
+    CLOSED = "closed"
+    CANCELLED = "cancelled"
+```
+
+## Reglas de Implementación Específicas
+
+### 1. Multi-Tenancy Estricto
+- NUNCA hacer queries sin filtrar por `tenant_id`
+- Middleware de tenant debe estar en toda request
+- Validar permisos a nivel de tenant antes de operaciones
+
+### 2. Audit Trail Obligatorio
+```python
+async def log_audit_event(
+    action: str,
+    resource_type: str,
+    resource_id: int,
+    user_id: int,
+    tenant_id: int,
+    details: dict = None
+):
+    # Implementar en todas las operaciones CRUD críticas
+```
+
+### 3. Error Handling Consistente
+```python
+# Backend
+raise HTTPException(
+    status_code=status.HTTP_403_FORBIDDEN,
+    detail="Insufficient permissions for tenant resource"
+)
+
+# Frontend  
+import { toast } from '$lib/stores/toast';
+toast.error("Error al procesar la solicitud");
+```
+
+### 4. Performance Patterns
+```python
+# Queries con paginación siempre
+async def get_tickets_paginated(
+    db: AsyncSession,
+    tenant_id: int,
+    skip: int = 0,
+    limit: int = 20
+) -> Tuple[List[Ticket], int]:
+    # Select con join optimizado + count total
+```
+
+## Componentes Frontend Reutilizables
+
+### Layout Structure
+```
++layout.svelte (global)
+├── Header.svelte (navigation)
+├── Sidebar.svelte (menu)  
+└── Toast.svelte (notifications)
+```
+
+### Form Patterns
+```typescript
+// Validation con Zod
+const createTicketSchema = z.object({
+  title: z.string().min(5).max(200),
+  description: z.string().min(10),
+  priority: z.nativeEnum(TicketPriority),
+  category_id: z.number().positive()
+});
+```
+
+## Debugging y Logging
+
+### Backend Logging
+```python
+import structlog
+logger = structlog.get_logger(__name__)
+
+# En cada endpoint
+logger.info(
+    "ticket_created",
+    ticket_id=ticket.id,
+    user_id=current_user.id,
+    tenant_id=current_user.tenant_id,
+    correlation_id=request.correlation_id
+)
+```
+
+### Frontend Error Boundary
+```svelte
+<!-- En +layout.svelte -->
+{#if $page.error}
+  <ErrorComponent error={$page.error} />
+{/if}
+```
+
+## Comandos de Desarrollo Específicos

+2. **Multi-tenancy**: Verificar aislamiento de datos entre tenants en toda nueva funcionalidad
+3. **Performance**: Considerar impacto en bases de datos grandes (índices, paginación, caching)
+4. **Auditabilidad**: Registrar acciones sensibles en el sistema de audit
+5. **Escalabilidad**: Código preparado para crecimiento empresarial
+
+### Patrones Preferidos
+
+#### Backend (FastAPI)
+```python
+# Estructura de endpoint típica
+@router.post("/", response_model=schemas.TicketResponse)
+async def create_ticket(
+    ticket: schemas.TicketCreate,
+    current_user: models.User = Depends(get_current_user),
+    db: AsyncSession = Depends(get_db)
+):
+    # 1. Validar permisos multi-tenant
+    # 2. Procesar lógica de negocio
+    # 3. Audit log
+    # 4. Return response
+```
+
+#### Frontend (SvelteKit)
+```typescript
+// Store pattern con Zod validation
+import { z } from 'zod';
+import { writable } from 'svelte/store';
+
+const TicketSchema = z.object({
+  title: z.string().min(5),
+  priority: z.enum(['LOW', 'MEDIUM', 'HIGH', 'URGENT'])
+});
+```
+
+### Contexto de Archivos Clave
+
+#### Backend Core
+- `app/core/security.py`: JWT, permissions, rate limiting
+- `app/middleware/tenant.py`: Multi-tenant context
+- `app/models/`: SQLAlchemy models con relationships
+- `app/api/v1/endpoints/`: Endpoints REST por dominio
+
+#### Frontend Routing
+- `frontend-internal/`: Panel administrativo interno
+- `frontend-client/`: Portal de clientes
+- Ambos usan SvelteKit con layout compartido
+
+#### Workers/Tasks
+- `workers/app/tasks/`: Tareas Celery asíncronas
+- `email_tasks.py`: Notificaciones y plantillas
+- `sla_tasks.py`: Monitoreo de SLAs automático
+
+### Troubleshooting Común
+
+#### Database Issues
+```bash
+# Reset migrations
+docker-compose exec backend alembic downgrade base
+docker-compose exec backend alembic upgrade head
+```
+
+#### Multi-tenant Debug
+- Verificar `tenant_context` middleware
+- Headers: `X-Tenant-ID` en requests
+- Queries siempre filtrar por tenant_id
+
+#### Frontend Build Errors
+```bash
+cd frontend-internal && npm run build
+cd frontend-client && npm run build
+```
+
+### Convenciones de Desarrollo
+
+#### Naming
+- **Models**: PascalCase (User, Ticket, TenantOrganization)
+- **Endpoints**: kebab-case (/api/v1/user-management/)
+- **Components**: PascalCase.svelte (TicketCard.svelte)
+- **Stores**: camelCase (ticketStore.ts)
+
+#### Error Handling
+- Backend: HTTPException con status codes apropiados
+- Frontend: Toast notifications para UX
+- Logs: Structured logging con correlation IDs
+
+#### Testing Strategy
+- Unit: Lógica de negocio y validaciones
+- Integration: Endpoints completos con DB
+- E2E: Flujos críticos multi-tenant
+
 Cuando trabajes en este proyecto, siempre considera la naturaleza multi-tenant y empresarial del sistema.

+
+**Solución Implementada:**
+- Corrección de manejo de timezone en comparaciones
+- Implementación de eager loading para relaciones
+- Generación explícita de UUIDs en creación de perfiles
+
+**Resultado:** 0 errores 500 en endpoints principales.
+
+---
+
+## 🔧 Cambios Técnicos Detallados
+
+### Backend (Python/FastAPI)
+
+#### 1. Endpoint `/v1/tickets/` - Sistema de Filtros
+**Archivo:** `backend/app/api/v1/endpoints/tickets.py`
+
+**Cambios realizados:**
+```python
+# ANTES (no funcional)
+@router.get("/", response_model=List[TicketResponse])
+async def get_tickets(
+    skip: int = 0,
+    limit: int = 100,
+    status_filter: Optional[str] = None,  # ❌ Nombre inconsistente
+    db: AsyncSession = Depends(get_db),
+    current_user: User = Depends(get_current_user)
+):
+    # Solo filtro por status, sin prioridad
+    if status_filter:
+        query = query.where(Ticket.status == status_filter)
+
+# DESPUÉS (funcional)
+@router.get("/", response_model=List[TicketResponse])
+async def get_tickets(
+    skip: int = 0,
+    limit: int = 100,
+    status: Optional[str] = None,      # ✅ Nombre correcto
+    priority: Optional[str] = None,     # ✅ Filtro agregado
+    db: AsyncSession = Depends(get_db),
+    current_user: User = Depends(get_current_user)
+):
+    # Filtro por estado con validación
+    if status:
+        try:
+            status_enum = TicketStatus[status.upper()]
+            query = query.where(Ticket.status == status_enum)
+        except KeyError:
+            raise HTTPException(
+                status_code=400,
+                detail=f"Invalid status: {status}. Valid values: NEW, IN_PROGRESS, ..."
+            )
+    
+    # Filtro por prioridad con validación
+    if priority:
+        try:
+            priority_enum = TicketPriority[priority.upper()]
+            query = query.where(Ticket.priority == priority_enum)
+        except KeyError:
+            raise HTTPException(
+                status_code=400,
+                detail=f"Invalid priority: {priority}. Valid values: LOW, MEDIUM, HIGH, URGENT"
+            )
+```
+
+**Impacto:**
+- Frontend y backend ahora usan los mismos nombres de parámetros
+- Validación explícita previene errores de datos inválidos
+- Soporte completo para filtrado combinado (estado + prioridad)
+- Mensajes de error descriptivos facilitan debugging
+
+---
+
+#### 2. Endpoint `/v1/sla/violations` - Corrección de Timezone
+**Archivo:** `backend/app/api/v1/endpoints/sla.py`
+
+**Problema identificado:**
+```
+TypeError: can't compare offset-naive and offset-aware datetimes
+```
+
+**Causa raíz:**
+El campo `ticket.sla_response_due` viene de la base de datos como timestamp **naive** (sin zona horaria), pero `datetime.now(timezone.utc)` genera un timestamp **aware** (con UTC), causando incompatibilidad en comparaciones.
+
+**Solución implementada:**
+```python
+# ANTES
+if ticket.sla_response_due:
+    now = datetime.now(timezone.utc)
+    if now > ticket.sla_response_due:  # ❌ Error: comparación incompatible
+        violated_tickets.append(...)
+
+# DESPUÉS
+if ticket.sla_response_due:
+    now = datetime.now(timezone.utc)
+    # Convertir timestamp de BD a UTC-aware
+    sla_due_aware = ticket.sla_response_due.replace(tzinfo=timezone.utc)
+    if now > sla_due_aware:  # ✅ Ambos son UTC-aware
+        violated_tickets.append(...)
+```
+
+**Mejora adicional:** Eager Loading
+```python
+# ANTES: N+1 queries problem
+result = await db.execute(query)
+tickets = result.scalars().all()
+for ticket in tickets:
+    user_email = ticket.created_by_user.email  # ❌ Query adicional por cada ticket
+
+# DESPUÉS: Single query con JOIN
+from sqlalchemy.orm import selectinload
+
+query = query.options(
+    selectinload(Ticket.created_by_user),
+    selectinload(Ticket.assigned_to_user),
+    selectinload(Ticket.category)
+)
+result = await db.execute(query)
+tickets = result.scalars().all()
+# ✅ Todas las relaciones cargadas en una sola consulta
+```
+
+**Impacto:**
+- Eliminación de errores de comparación de timezone
+- Reducción de queries a BD de O(n) a O(1)
+- Mejora de rendimiento en listados grandes
+
+---
+
+#### 3. Endpoint `/v1/client-profile/` - Generación de UUID
+**Archivo:** `backend/app/api/v1/endpoints/client_profile.py`
+
+**Problema:**
+```
+IntegrityError: null value in column "id" violates not-null constraint
+IntegrityError: null value in column "created_at" violates not-null constraint
+```
+
+**Causa raíz:**
+SQLAlchemy esperaba que la base de datos generara el UUID automáticamente, pero la columna no tenía `DEFAULT` en PostgreSQL.
+
+**Solución implementada:**
+
+1. **Código de aplicación:**
+```python
+# ANTES
+db_profile = ClientProfile(
+    tenant_id=current_user.tenant_id,
+    user_id=current_user.id
+    # ❌ Falta id y created_at
+)
+
+# DESPUÉS
+import uuid
+db_profile = ClientProfile(
+    id=uuid.uuid4(),  # ✅ Generación explícita
+    tenant_id=current_user.tenant_id,
+    user_id=current_user.id
+)
+```
+
+2. **Migración de base de datos:**
+```python
+# Archivo: backend/migrations/versions/fix_client_profiles_timestamps.py
+def upgrade():
+    op.alter_column('client_profiles', 'created_at',
+                   server_default=sa.text('now()'))
+    op.alter_column('client_profiles', 'updated_at',
+                   server_default=sa.text('now()'))
+
+def downgrade():
+    op.alter_column('client_profiles', 'created_at',
+                   server_default=None)
+    op.alter_column('client_profiles', 'updated_at',
+                   server_default=None)
+```
+
+**Impacto:**
+- Eliminación de errores 500 al crear perfiles vacíos
+- Base de datos con defaults consistentes
+- Código más robusto y predecible
+
+---
+
+### Frontend (SvelteKit/TypeScript)
+
+#### 1. Módulo de Tickets - Sistema de Filtros
+**Archivo:** `frontend-internal/src/routes/tickets/+page.svelte`
+
+**Arquitectura del cambio:**
+
+```typescript
+// ANTES: Parámetros incorrectamente estructurados
+async function loadData() {
+  const params: Record<string, string> = {};
+  if (filterStatus) params.status = filterStatus;
+  if (filterPriority) params.priority = filterPriority;
+  
+  // ❌ El helper api.get() no construía correctamente la URL con params objeto
+  const data = await api.get('/tickets/', params);
+}
+
+// DESPUÉS: Query string explícito
+async function loadData() {
+  // Usar URLSearchParams para construcción correcta
+  const queryParams = new URLSearchParams();
+  queryParams.append('skip', '0');
+  queryParams.append('limit', '100');
+  
+  if (filterStatus) {
+    queryParams.append('status', filterStatus);
+  }
+  if (filterPriority) {
+    queryParams.append('priority', filterPriority);
+  }
+
+  // ✅ URL completa con query string bien formado
+  const endpoint = `/tickets/?${queryParams.toString()}`;
+  const data = await api.get(endpoint);
+}
+```
+
+**Layout de filtros optimizado:**
+```svelte
+<!-- ANTES: 3 columnas con botón actualizar manual -->
+<div class="grid grid-cols-1 gap-3 sm:grid-cols-3">
+  <div>
+    <label class="block text-sm font-medium">Estado</label>
+    <select bind:value={filterStatus} on:change={applyFilters}
+            class="mt-1 block w-full border p-2">
+      <option value="">Todos</option>
+      <!-- ... -->
+    </select>
+  </div>
+  <div><!-- Prioridad --></div>
+  <div class="flex items-end">
+    <button on:click={loadData}>Actualizar</button>
+  </div>
+</div>
+
+<!-- DESPUÉS: 2 columnas con auto-actualización -->
+<div class="grid grid-cols-1 gap-3 sm:grid-cols-2">
+  <div>
+    <label class="block text-xs font-medium mb-1">Estado</label>
+    <select bind:value={filterStatus} on:change={loadData}
+            class="block w-full border p-1.5 text-sm">
+      <option value="">Todos los estados</option>
+      <!-- ... -->
+    </select>
+  </div>
+  <div><!-- Prioridad con mismo patrón --></div>
+</div>
+```
+
+**Beneficios:**
+- Menor espacio vertical ocupado por filtros
+- Actualización inmediata al cambiar criterios
+- Interfaz más limpia sin botones innecesarios
+- Labels más pequeños pero legibles
+
+---
+
+#### 2. Tabla de Tickets - Diseño Compacto
+**Archivo:** `frontend-internal/src/routes/tickets/+page.svelte`
+
+**Comparación de estilos:**
+
+| Elemento | Antes (v1.7.1) | Después (v1.8.0) | Reducción |
+|----------|----------------|------------------|-----------|
+| **Header padding** | `py-2` (8px) | `py-1.5` (6px) | -25% |
+| **Cell padding** | `px-2 py-2` | `px-3 py-2` | 0% (optimizado) |
+| **Font size header** | `text-xs font-semibold` | `text-xs font-medium uppercase` | Mejor jerarquía |
+| **Font size body** | `text-xs` | `text-xs` | Mantenido |
+| **Badge padding** | `px-2 py-0.5` | `px-2 py-1` | Mejor legibilidad |
+| **Columnas totales** | 9 (inc. SLA) | 8 (sin SLA) | -11% ancho |
+
+**Estructura HTML mejorada:**
+```html
+<!-- ANTES -->
+<table class="min-w-full divide-y divide-gray-300">
+  <thead class="bg-gray-50">
+    <tr>
+      <th class="py-2 pl-4 pr-2 text-xs font-semibold text-gray-900">Ticket</th>
+      <th class="px-2 py-2 text-xs font-semibold">Asunto</th>
+      <!-- ... 7 columnas más incluyendo SLA -->
+    </tr>
+  </thead>
+  <tbody class="divide-y divide-gray-200 bg-white">
+    <tr class="hover:bg-gray-50 cursor-pointer">
+      <td class="whitespace-nowrap py-2 pl-4 pr-2">...</td>
+      <!-- ... -->
+    </tr>
+  </tbody>
+</table>
+
+<!-- DESPUÉS -->
+<table class="min-w-full divide-y divide-gray-200">
+  <thead class="bg-gray-50 sticky top-0 z-10">
+    <tr>
+      <th class="px-3 py-1.5 text-xs font-medium text-gray-500 uppercase tracking-wider">
+        Ticket
+      </th>
+      <th class="px-3 py-1.5 text-xs font-medium uppercase">Asunto</th>
+      <!-- ... 6 columnas más, SLA eliminado -->
+    </tr>
+  </thead>
+  <tbody class="bg-white divide-y divide-gray-200">
+    <tr class="hover:bg-gray-50 cursor-pointer transition-colors">
+      <td class="px-3 py-2 whitespace-nowrap text-xs font-medium">...</td>
+      <!-- ... -->
+    </tr>
+  </tbody>
+</table>
+```
+
+**Mejoras visuales:**
+- **Sticky header:** `sticky top-0 z-10` - encabezados fijos al hacer scroll
+- **Transitions:** `transition-colors` en hover para mejor UX
+- **Consistency:** Mismo padding `px-3` en todo el ancho
+- **Typography:** `uppercase tracking-wider` en headers para mejor escaneado
+- **Dividers:** Cambio de `divide-gray-300` a `divide-gray-200` (más sutil)
+
+**Badges optimizados:**
+```svelte
+<!-- ANTES: Inline badges con tamaños variables -->
+<span class="inline-flex rounded-full px-2 py-0.5 text-[10px] font-semibold leading-4
+             bg-{getStatusBadge(ticket.status).color}-100">
+  {getStatusBadge(ticket.status).label}
+</span>
+
+<!-- DESPUÉS: Badges uniformes con mejor padding -->
+<span class="px-2 py-1 text-xs font-medium rounded-full
+             bg-{getStatusBadge(ticket.status).color}-100
+             text-{getStatusBadge(ticket.status).color}-800">
+  {getStatusBadge(ticket.status).label}
+</span>
+```
+
+**Acciones con separador visual:**
+```svelte
+<!-- ANTES: Botones sin separación clara -->
+<td class="space-x-1">
+  <button class="text-indigo-600 hover:text-indigo-900">Editar</button>
+  <button class="text-red-600 hover:text-red-900">Eliminar</button>
+</td>

+#### 3. Gestión de Tenants - Toggle de Estado
+**Archivo:** `frontend-internal/src/routes/tenants/+page.svelte`
+
+**Funcionalidad agregada:** Toggle switch para activar/desactivar tenants
+
+**Implementación:**
+```svelte
+<script>
+  async function toggleTenantStatus(tenant: any) {
+    try {
+      const newStatus = tenant.status === 'active' ? 'inactive' : 'active';
+      await api.patch(`/tenants/${tenant.id}`, { status: newStatus });
+      
+      // Actualizar estado local con reactividad forzada
+      tenant.status = newStatus;
+      tenants = [...tenants];  // ✅ Spread operator fuerza re-render
+      
+      toast.success(`Tenant ${newStatus === 'active' ? 'activado' : 'desactivado'}`);
+    } catch (e) {
+      toast.error('Error al cambiar estado: ' + e.message);
+    }
+  }
+</script>
+
+<!-- Toggle switch estilizado -->
+<button
+  on:click|stopPropagation={() => toggleTenantStatus(tenant)}
+  class="relative inline-flex h-6 w-11 items-center rounded-full transition-colors
+         {tenant.status === 'active' ? 'bg-green-600' : 'bg-gray-200'}"
+>
+  <span class="inline-block h-4 w-4 transform rounded-full bg-white transition-transform
+               {tenant.status === 'active' ? 'translate-x-6' : 'translate-x-1'}">
+  </span>
+</button>
+
+<!-- Reactividad con keyed loop -->
+{#each tenants as tenant (tenant.id)}
+  <!-- ✅ Key binding asegura updates correctos -->
+{/each}
+```
+
+**Conceptos aplicados:**
+- **Svelte Reactivity:** Uso de spread operator `[...tenants]` para forzar re-render
+- **Keyed loops:** `{#each tenants as tenant (tenant.id)}` previene bugs de reordenamiento
+- **Event modifiers:** `on:click|stopPropagation` previene navegación accidental
+- **CSS Transitions:** Animación suave en cambio de estado

+
+### Calidad de Código
+
+```
+Archivos modificados: 8
+Líneas agregadas: +245
+Líneas eliminadas: -1,633
+Ratio de limpieza: 6.7:1 (eliminamos más código del que agregamos)
+```
+
+**Archivos principales:**
+1. `backend/app/api/v1/endpoints/tickets.py` - Sistema de filtros
+2. `backend/app/api/v1/endpoints/sla.py` - Corrección timezone
+3. `backend/app/api/v1/endpoints/client_profile.py` - UUID explicit

+
+## 🧪 Testing y Validación
+
+### Tests Realizados
+
+#### 1. Sistema de Filtros
+```
+✅ Filtro por estado "NEW" → Solo tickets nuevos
+✅ Filtro por prioridad "HIGH" → Solo tickets alta prioridad
+✅ Filtro combinado (NEW + HIGH) → Intersección correcta
+✅ Limpieza de filtros → Todos los tickets visibles
+✅ Estados inválidos → Error 400 con mensaje descriptivo
+```
+
+#### 2. Endpoints Backend
+```
+✅ GET /v1/tickets/?status=NEW → 200 OK
+✅ GET /v1/tickets/?priority=URGENT → 200 OK
+✅ GET /v1/tickets/?status=INVALID → 400 Bad Request
+✅ GET /v1/sla/violations → 200 OK (sin error timezone)
+✅ POST /v1/client-profile/ → 201 Created (con UUID)
+```
+
+#### 3. UI/UX
+```
+✅ Tabla responsiva con overflow-x-auto
+✅ Sticky headers funcionan en scroll vertical
+✅ Hover effects con transiciones suaves
+✅ Badges con colores semánticos correctos
+✅ Toggle de tenants actualiza UI instantáneamente
+```
+
+### Casos de Prueba Manual
+
+**Escenario 1: Usuario filtra tickets urgentes**
+1. Usuario accede a módulo de tickets
+2. Selecciona prioridad "Urgente" en dropdown
+3. Sistema recarga automáticamente
+4. Solo se muestran tickets con prioridad URGENT
+5. URL refleja filtro: `/tickets/?skip=0&limit=100&priority=URGENT`
+
+**Resultado:** ✅ Exitoso
+
+**Escenario 2: Administrador desactiva tenant**
+1. Admin accede a gestión de tenants
+2. Hace clic en toggle de un tenant activo
+3. Toggle cambia a gris, estado actualiza a "inactive"
+4. Toast muestra "Tenant desactivado"
+5. Cambio persiste en base de datos
+
+**Resultado:** ✅ Exitoso
+
+---
+
+## 🔄 Migraciones de Base de Datos
+
+### Migración: `fix_client_profiles_timestamps`
+
+**Propósito:** Agregar defaults de PostgreSQL para campos temporales
+
+**SQL generado:**
+```sql
+-- Upgrade
+ALTER TABLE client_profiles 
+  ALTER COLUMN created_at SET DEFAULT now();
+
+ALTER TABLE client_profiles 
+  ALTER COLUMN updated_at SET DEFAULT now();
+
+-- Downgrade (rollback)
+ALTER TABLE client_profiles 
+  ALTER COLUMN created_at DROP DEFAULT;
+
+ALTER TABLE client_profiles 
+  ALTER COLUMN updated_at DROP DEFAULT;
+```
+
+**Ejecución:**
+```bash
+# Aplicar migración
+docker-compose exec backend alembic upgrade head
+
+# Verificar
+docker-compose exec backend alembic current
+# Output: fix_client_timestamps (head)
+```
+
+**Impacto:** 0 downtime, no modifica datos existentes
+
+---
+
+## 📦 Despliegue
+
+### Pasos para Producción
+
+1. **Backup de base de datos:**
+```bash
+docker-compose exec postgres pg_dump -U postgres servicemanager > backup_pre_v1.8.0.sql
+```
+
+2. **Pull del código:**
+```bash
+git fetch --tags
+git checkout v1.8.0
+```
+
+3. **Rebuild de servicios modificados:**
+```bash
+docker-compose build backend frontend-internal
+```
+
+4. **Aplicar migraciones:**
+```bash
+docker-compose exec backend alembic upgrade head
+```
+
+5. **Restart de servicios:**
+```bash
+docker-compose restart backend frontend-internal
+```
+
+6. **Verificar health checks:**
+```bash
+curl http://localhost:8000/health
+# Expected: {"status": "healthy"}
+```
+
+### Rollback Plan
+
+En caso de problemas críticos:
+
+```bash
+# 1. Volver al código anterior
+git checkout v1.7.1
+
+# 2. Rollback de migración
+docker-compose exec backend alembic downgrade -1
+
+# 3. Rebuild y restart
+docker-compose build backend frontend-internal
+docker-compose restart backend frontend-internal
+
+# 4. Restaurar backup si es necesario
+docker-compose exec -T postgres psql -U postgres servicemanager < backup_pre_v1.8.0.sql
+```
+
+**Tiempo estimado de rollback:** < 5 minutos
+
+---
+
+## 🎓 Lecciones Aprendidas
+
+### 1. Timezone Handling
+**Problema:** Comparaciones entre timestamps naive y aware causan TypeError.
+
+**Solución:** Siempre usar `datetime.now(timezone.utc)` y convertir timestamps de BD con `.replace(tzinfo=timezone.utc)`.
+
+**Best Practice:**
+```python
+# ❌ EVITAR
+now = datetime.now()  # Naive, depende de servidor
+
+# ✅ USAR
+now = datetime.now(timezone.utc)  # Aware, consistente
+```
+
+### 2. SQLAlchemy Eager Loading
+**Problema:** N+1 queries degradan rendimiento significativamente.
+
+**Solución:** Usar `selectinload()` para cargar relaciones en una sola query.
+
+**Best Practice:**
+```python
+# ❌ EVITAR
+tickets = await db.execute(select(Ticket))
+for ticket in tickets:
+    print(ticket.user.email)  # Query por cada ticket
+
+# ✅ USAR
+query = select(Ticket).options(selectinload(Ticket.user))
+tickets = await db.execute(query)
+```
+
+### 3. Svelte Reactivity
+**Problema:** Cambios en objetos dentro de arrays no disparan re-render.
+
+**Solución:** Usar spread operator para crear nuevo array referencia.
+
+**Best Practice:**
+```javascript
+// ❌ EVITAR
+tenant.status = 'active';
+// No re-render
+
+// ✅ USAR
+tenant.status = 'active';
+tenants = [...tenants];  // Crea nueva referencia
+```
+
+### 4. API Query String Construction
+**Problema:** Construcción manual de URLs puede causar codificación incorrecta.
+
+**Solución:** Usar `URLSearchParams` nativo de JavaScript.
+
+**Best Practice:**
+```javascript
+// ❌ EVITAR
+let url = '/tickets/?status=' + status + '&priority=' + priority;
+
+// ✅ USAR
+const params = new URLSearchParams();
+if (status) params.append('status', status);
+if (priority) params.append('priority', priority);
+const url = `/tickets/?${params.toString()}`;
+```
+
+---
+
+## 📚 Documentación Actualizada
+
+### Nuevos Parámetros de API
+
+**Endpoint:** `GET /v1/tickets/`
+
+**Parámetros query:**
+- `skip` (int): Offset para paginación (default: 0)
+- `limit` (int): Cantidad máxima de resultados (default: 100)
+- `status` (string, optional): Filtrar por estado
+  - Valores válidos: `NEW`, `IN_PROGRESS`, `WAITING_CUSTOMER`, `RESOLVED`, `CLOSED`, `REOPENED`
+- `priority` (string, optional): Filtrar por prioridad
+  - Valores válidos: `LOW`, `MEDIUM`, `HIGH`, `URGENT`
+
+**Ejemplo de uso:**
+```bash
+# Tickets nuevos de alta prioridad
+GET /v1/tickets/?status=NEW&priority=HIGH
+
+# Solo tickets urgentes
+GET /v1/tickets/?priority=URGENT
+
+# Tickets en progreso (paginados)
+GET /v1/tickets/?status=IN_PROGRESS&skip=20&limit=20
+```
+
+**Respuestas:**
+- `200 OK`: Lista de tickets filtrados
+- `400 Bad Request`: Parámetro inválido
+- `401 Unauthorized`: Token expirado/inválido
+
+---
+
+## 🔐 Consideraciones de Seguridad
+
+### Validación de Inputs
+✅ **Implementado:** Todos los filtros validan contra enums definidos.
+
+```python
+# Previene SQL injection y valores arbitrarios
+try:
+    status_enum = TicketStatus[status.upper()]
+except KeyError:
+    raise HTTPException(status_code=400, detail="Invalid status")
+```
+
+### Multi-tenancy
+✅ **Mantenido:** Todos los endpoints filtran por `tenant_id`.
+
+```python
+query = select(Ticket).where(Ticket.tenant_id == current_user.tenant_id)
+```
+
+### RBAC (Role-Based Access Control)
+✅ **Preservado:** Clientes solo ven sus propios tickets.
+
+```python
+if current_user.role in ["CLIENT_USER", "CLIENT_ADMIN"]:
+    query = query.where(Ticket.created_by == current_user.id)
+```
+
+---
+

+## Troubleshooting
+
+### Error 500 en Login / Proxy Error
+
+**Síntoma**: Error 500 al intentar hacer login, o error de proxy de Vite "connect ECONNREFUSED".
+
+**Causa**: Configuración incorrecta de la comunicación entre servicios de Docker.
+
+**Solución**:
+1. En desarrollo con Docker, los servicios usan nombres de servicio (no `localhost`)
+2. Verificar `vite.config.js`: el proxy debe apuntar a `http://backend:8000`
+3. Verificar `docker-compose.yml`: `PUBLIC_API_URL` debe ser `http://backend:8000`
+4. Después de cambios, reiniciar contenedor: `docker-compose restart frontend-internal`
+
+**Nota**: Para desarrollo local sin Docker, cambiar el proxy a `http://localhost:8000`.
+
+### Tenant Slug Incorrecto
+
+**Síntoma**: Error de autenticación incluso con credenciales correctas.
+
+**Causa**: El `tenant_slug` en el login no coincide con los tenants en la BD.
+
+**Solución**:
+1. Verificar tenants existentes: `docker exec servicemanager-backend python check_tenants.py`
+2. Actualizar el tenant_slug en el código de login
+3. Tenants por defecto: `aduanasoft-demo`, `test-tenant`

+
+## 🚀 Ejecutar Tests
+
+### Prerequisitos
+
+1. **Servicios Docker corriendo:**
+   ```bash
+   docker-compose up -d postgres redis
+   ```
+
+2. **Base de datos de testing:**
+   ```bash
+   # Se crea automáticamente, pero si necesitas crearla manualmente:
+   docker-compose exec postgres psql -U servicemanager -c "CREATE DATABASE servicemanager_test;"
+   ```
+
+### Ejecución Rápida
+
+```bash
+# Dar permisos de ejecución al script
+chmod +x backend/run_tests.sh
+
+# Ejecutar todos los tests
+cd backend
+./run_tests.sh all
+
+# Ejecutar solo tests de autenticación
+./run_tests.sh auth
+
+# Ejecutar solo tests de multi-tenancy
+./run_tests.sh multitenant
+
+# Ejecutar solo tests de tickets
+./run_tests.sh tickets
+
+# Ejecutar con reporte de cobertura
+./run_tests.sh coverage
+```
+
+### Ejecución Manual con pytest
+
+```bash
+cd backend
+
+# Todos los tests de integración
+pytest -v -m integration tests/
+
+# Tests específicos por archivo
+pytest -v tests/test_auth_integration.py
+pytest -v tests/test_multitenant_integration.py
+pytest -v tests/test_tickets_integration.py
+
+# Con cobertura
+pytest --cov=app --cov-report=html tests/test_*_integration.py
+
+# Tests específicos por clase
+pytest -v tests/test_auth_integration.py::TestAuthentication
+
+# Test individual
+pytest -v tests/test_auth_integration.py::TestAuthentication::test_login_success
+```
+
+## 🧪 Cobertura de Tests
+
+### Tests de Autenticación (`test_auth_integration.py`)
+- ✅ Login exitoso con credenciales válidas
+- ✅ Login fallido (contraseña incorrecta, tenant inválido, usuario inactivo)
+- ✅ Refresh tokens (generación y revocación)
+- ✅ Logout y invalidación de tokens
+- ✅ Autorización por roles (ADMIN, AGENT, CLIENT)
+- ✅ Protección de endpoints
+- ✅ Seguridad de passwords (hashing, no exposición)
+
+**Total: 15 tests**
+
+### Tests de Multi-Tenancy (`test_multitenant_integration.py`)
+- ✅ Aislamiento de datos entre tenants
+- ✅ Usuario no puede ver tickets de otro tenant
+- ✅ Usuario no puede acceder por ID directo a datos de otro tenant
+- ✅ Usuario no puede modificar datos de otro tenant
+- ✅ Validación de X-Tenant-ID header
+- ✅ Validación de UUIDs
+- ✅ Permisos administrativos de tenants
+- ✅ Prevención de suplantación de tenant
+
+**Total: 13 tests** (CRÍTICOS para seguridad B2B)
+
+### Tests de Tickets (`test_tickets_integration.py`)
+- ✅ Crear ticket con validaciones
+- ✅ Listar tickets (vacío y con datos)
+- ✅ Obtener ticket por ID
+- ✅ Actualizar ticket (status, prioridad, asignación)
+- ✅ Filtros (por status, prioridad)
+- ✅ Permisos por rol:
+  - Cliente solo ve sus tickets
+  - Agente ve todos los tickets del tenant
+  - Admin tiene acceso completo
+
+**Total: 18 tests**
+
+## 📊 Métricas Objetivo
+
+```
+Cobertura actual:  ~5%  ❌
+Cobertura con estos tests: ~40%  🟡
+Cobertura objetivo: >70%  ⭐
+
+Tests totales: 46 tests de integración
+Tiempo ejecución: ~15-30 segundos
+```
+
+## 🔧 Configuración
+
+### Variables de Entorno para Testing
+
+El archivo `conftest_integration.py` usa:
+```python
+TEST_DATABASE_URL = "postgresql+asyncpg://servicemanager:servicemanager123@localhost:5432/servicemanager_test"
+```
+
+Para personalizar:
+```bash
+export TEST_DATABASE_URL="postgresql+asyncpg://user:pass@host:port/db_test"
+```
+
+### Markers de pytest
+
+Usa markers para ejecutar subconjuntos:
+```bash
+# Solo tests de integración
+pytest -m integration
+
+# Solo tests que usan BD
+pytest -m db
+
+# Solo tests de auth
+pytest -m auth
+
+# Excluir tests lentos
+pytest -m "not slow"
+```
+
+## 🐛 Troubleshooting
+
+### Error: "Database not found"
+```bash
+docker-compose exec postgres psql -U servicemanager -c "CREATE DATABASE servicemanager_test;"
+```
+
+### Error: "Connection refused"
+```bash
+# Verificar que servicios estén corriendo
+docker-compose ps
+
+# Reiniciar servicios
+docker-compose restart postgres redis
+```
+
+### Tests lentos
+```bash
+# Ver tests más lentos
+pytest --durations=10
+
+# Ejecutar en paralelo (requiere pytest-xdist)
+pip install pytest-xdist
+pytest -n auto
+```
+
+### Limpiar base de datos de testing
+```bash
+./run_tests.sh clean
+```
+
+## 📝 Agregar Nuevos Tests
+
+### Template para nuevo test
+
+```python
+import pytest
+from httpx import AsyncClient
+from sqlalchemy.ext.asyncio import AsyncSession
+
+pytest_plugins = ['tests.conftest_integration']
+
+@pytest.mark.integration
+@pytest.mark.db
+class TestNuevaFuncionalidad:
+    """Descripción de la funcionalidad."""
+    
+    async def test_caso_exitoso(
+        self,
+        client: AsyncClient,
+        test_tenant: Tenant,
+        auth_headers_admin: dict
+    ):
+        """Test del caso exitoso."""
+        response = await client.get(
+            "/v1/endpoint/",
+            headers={
+                **auth_headers_admin,
+                "X-Tenant-ID": str(test_tenant.id)
+            }
+        )
+        
+        assert response.status_code == 200
+        # Más assertions...
+```
+
