# 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

```bash
# Backend development
cd backend && uvicorn app.main:app --reload --port 8000

# Frontend internal (admin panel)  
cd frontend-internal && npm run dev -- --port 3001

# Frontend client (customer portal)
cd frontend-client && npm run dev -- --port 3000

# Workers
cd workers && celery -A app.celery worker --loglevel=info

# Full stack con Docker
docker-compose -f docker-compose.dev.yml up

# Database operations
docker-compose exec backend alembic revision --autogenerate -m "Description"
docker-compose exec backend alembic upgrade head

# Testing complete
docker-compose exec backend pytest -v --cov=app
```
