## 9. Kända Begränsningar

1. **ONNX-modeller**
   - Status: Fallback-läge aktivt
   - Påverkan: Simulerade detektioner istället för AI
   - Lösning: Träna och deploya ONNX-modeller

2. **Bildlagring**
   - Status: Lokal lagring i demo
   - Påverkan: Ingen persistens mellan omstarter
   - Lösning: Konfigurera S3/MinIO

3. **Notifikationer**
   - Status: Mockade i tester
   - Påverkan: Inga verkliga email/SMS skickas
   - Lösning: Konfigurera SMTP/Twilio

---

## 10. Rekommendationer

### Innan produktion
1. [ ] Träna ONNX-modeller med verkliga bilder
2. [ ] Konfigurera S3-bucket för bildlagring
3. [ ] Sätt upp SMTP/Twilio för notifikationer
4. [ ] Kör belastningstest med 1000+ objekt
5. [ ] Säkerhetsgranskning (penetrationstest)

### Förbättringar
1. [ ] Öka testtäckning till >90%
2. [ ] Lägg till end-to-end tester med Playwright
3. [ ] Implementera caching för dashboard
4. [ ] Lägg till rate limiting per API-nyckel
