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 +- Backend: App imports successfully, router registered at /api/v1/retouch +- Frontend: All 3 components render without errors in test environment +- OpenRouter mocked in all backend tests (no real API calls) +- Background task mocked in router integration tests (avoids event loop conflicts)
