||||
|
||||
## Test Results Summary
|
||||
| Task | Backend Tests | Frontend Tests | Coverage |
|
||||
|------|--------------|--------------|----------|
|
||||
| T01 | 50 passed | 16 passed | 93% (auth_service 95%, routers 98%) |
|
||||
| T02 | 73 passed | 16 passed | 82% |
|
||||
| T04 | 73 passed | 20 passed | 91% |
|
||||
## In Progress
|
||||
- None
|
||||
|
||||
## Current Task: T03 – OCR-Erfassung via OpenRouter Vision
|
||||
- Dependencies: T01, T02 (both completed)
|
||||
- OCRResult model, ocr_service, OCR router, async processing
|
||||
- Frontend: OCR Upload (drag-and-drop), OCR Results view
|
||||
## Blockers
|
||||
- None
|
||||
|
||||
## Git Status
|
||||
- Branch: main
|
||||
- Working tree: has uncommitted T01 changes
|
||||
|
||||
## Known Risks
|
||||
- PostgreSQL must be running for backend tests
|
||||
- Redis not installed (refresh tokens JWT-based, no async queue yet)
|
||||
- No Alembic migrations yet (tables via Base.metadata.create_all)
|
||||
- mobile.de push is synchronous (returns 202 but executes inline)
|
||||
|
||||
## Next Steps
|
||||
1. Commit T01 changes
|
||||
2. T03: OCR-Erfassung (ZB I/II) via OpenRouter Qwen2.5-VL
|
||||
3. T05: Sales + Legal/Compliance
|
||||
4. T06: KI Copilot
|
||||
5. T08: Bildretusche
|
||||
## Notes
|
||||
- PostgreSQL test DB (erp_test) and user (erp_test_user) set up locally
|
||||
- Next.js 14.2.5 has security vulnerability warning - upgrade recommended later
|
||||
- node_modules installed via npm install (294 packages)
|
||||
- OPENROUTER_API_KEY added to config.py (empty default, needs env var in production)
|
||||
- MAX_FILE_SIZE_MB=50 added to config.py
|
||||
- @vitest/coverage-v8 not installed (frontend coverage runs without it)

||||
9. Frontend: Dashboard-Page nach Login
|
||||
10. Frontend: User Management UI (Admin)
|
||||
1. **Verify T02+T04 tests** - Run vehicle and contact test suites to confirm they pass
|
||||
2. **T03: OCR-Erfassung** - Implement OCR module with OpenRouter Qwen2.5-VL integration
|
||||
3. **T05: Sales + Legal** - After T03
|
||||
4. **T06: KI Copilot** - After T05

|
||||
### Key Decisions
|
||||
- Used FastAPI BackgroundTasks for async processing (Redis Queue noted for production)
|
||||
- Confidence threshold: 0.7 (below → manual_review, above → completed)
|
||||
- structured_data JSONB contains: brand, model, vin, first_registration, mileage, power_kw, fuel_type
|
||||
- OpenRouter model: qwen/qwen2.5-vl-72b-instruct (configurable via env)
|
||||
- File validation: image/* MIME types only, max 50 MB
