# Backend Integration

The frontend is intentionally backend-ready but backend-free.

Integration steps:

1. Implement an HTTP client in `src/api/client.ts`.
2. Replace mock methods in `src/api/services/panel-service.ts` with real service calls.
3. Preserve the response envelope and DTOs in `src/api/contracts`.
4. Map backend validation errors into `ApiError.fields`.
5. Add WebSocket/SSE adapters for jobs, terminal state, notifications, metrics, and logs.
6. Keep destructive actions behind typed confirmation, reason capture, two-factor confirmation, and audit-preview flows.
