 # Current Status
 
-**Task**: T01 – Auth + User Management + RBAC + Base Frontend Layout + i18n Setup
+**Task**: T02 – Vehicle Management + mobile.de Push + Vehicle UI
 **Status**: COMPLETED
 **Date**: 2026-07-14
 
 ## Summary
-Backend (FastAPI) und Frontend (Next.js 14) vollständig implementiert.
+Vehicle CRUD API with pagination/filtering/sorting, mobile.de push integration, and full frontend UI implemented.
 
 ## Backend (COMPLETED)
-- 10 Python-Dateien erstellt (config, database, models, schemas, utils, services, dependencies, routers, main)
-- 4 Test-Dateien mit 50 Tests – alle bestanden
-- Coverage: 88% total, auth_service 95%, routers 79-100%
-- PostgreSQL 18 als Test-DB (kein SQLite)
-- bcrypt Password-Hashing, JWT HS256, RBAC require_role
+- Vehicle model: UUID PK, all fields per spec (make, model, fin CHECK len=17, year, first_registration, power_kw, power_hp computed, fuel_type, transmission, color, condition, location, availability, price, vehicle_type, lkw_type, machine_type, body_type, operating_hours, operating_hours_unit, mileage_km, description, timestamps, deleted_at soft-delete)
+- MobileDeListing model: vehicle_id FK, ad_id, sync_status, synced_at, error_log
+- 7 API endpoints: GET /vehicles (list+filter+sort+paginate), POST /vehicles (create), GET /vehicles/:id (detail), PUT /vehicles/:id (update), DELETE /vehicles/:id (soft-delete), POST /vehicles/:id/mobile-de/push (202 async), GET /vehicles/:id/mobile-de/status
+- mobile.de service: push_listing, update_listing, delete_listing, get_listing_status, retry_failed_listing (max 3 retries)
+- Field mapping: map_fields() converts Vehicle to mobile.de Ad format (vin, firstRegistration YYYY-MM, mileage, price EUR, power, category, bodyType, sellerLocation)
+- All endpoints require JWT Bearer auth
+- Config: MOBILE_DE_API_KEY, MOBILE_DE_SELLER_ID env vars added
 
 ## Frontend (COMPLETED)
-- 6 UI-Komponenten (Button, Input, Card, Table, Modal, Toast)
-- Login-Page mit Form-Validation und Toast-Error-Handling
-- i18n mit DE/EN (31 Keys je Sprache)
-- 12 Vitest-Tests – alle bestanden
-- Next.js Production Build erfolgreich
+- VehicleList: Table with filters (search, type, availability, sort), pagination, error handling
+- VehicleForm: Create/edit form with validation (make, model, fin=17 chars, price>0, vehicle_type), conditional fields
+- VehicleDetail: All vehicle fields display, delete button, MobileDeStatus embedded
+- MobileDeStatus: Sync status badge, push button, ad_id, synced_at, error_log display
+- 3 pages: fahrzeuge list, fahrzeuge/neu create, fahrzeuge/[id] detail
 
 ## Test Evidence
-- Backend: 50/50 pytest passed, 88% coverage
-- Frontend: 12/12 vitest passed, Next.js build success
-- test_report.md erstellt mit vollständigen Ergebnissen
+- Backend: 73/73 pytest passed, 82% total coverage (vehicle_service 99%, mobilede_service 80%, router 60%)
+- Frontend: 16/16 vitest passed
+- test_report.md updated with full results
+- All mobile.de HTTP calls mocked in tests, no real API calls
+- Soft-delete verified: deleted_at set, vehicle excluded from list and detail queries
