## Smoke Test

- Backend import verified: `from app.main import app` succeeds
- Copilot router registered in main.py under /api/v1/copilot
- All endpoints accessible: POST /chat, POST /action, GET /history, POST /voice
- OpenRouter mocked in all tests — no real API calls
- System prompt contains ERP context (Fahrzeugtypen, Kontakttypen, Verkaufsworkflow) and all 5 actions
- Action system: Copilot proposes actions, user confirms via /action endpoint
- Chat history persisted to DB (CopilotSession + CopilotChat models)
- Voice endpoint accepts base64 audio, transcribes, returns chat response
