**Generated:** 2026-03-26  
**Auditor:** Projekt Manager Gemini  
**Timeline:** 4-6 Weeks to Production Readiness

---

## 🎯 Executive Summary

**Current Status:** 70% Complete (Backend/DB Stable, Frontend/Testing Incomplete)  
**Target:** 100% Production Ready  
**Critical Path:** Fix API mismatches → Complete frontend wiring → Implement analytics → Testing & deployment

### Overall Health Metrics
- **Database:** 100% (127+ tables across 19 schemas, synchronized)
- **Backend API:** 62% (51/87 core tables have working endpoints)
- **Frontend UI:** 61% (Components built but API wiring incomplete)
- **Robot Fleet:** 100% (10+ specialized workers operational)
- **Integration:** 40% (Frontend/backend API mismatches present)

---

## 🚨 CRITICAL BLOCKERS (Must Fix First)

### Blocker 1: Vehicle Creation Endpoint Mismatch
**Issue:** Frontend calls `/api/v1/vehicles/register` (404), backend provides `/api/v1/assets/vehicles`  
**Impact:** Users cannot add vehicles - core functionality broken  
**Fix:** 
1. Update frontend components (`AddVehicleModal.vue`, `QuickActionsFAB.vue`)
2. Or create redirect endpoint at `/api/v1/vehicles/register`
3. Test 2-step creation flow (Draft → Active)

**Estimated Effort:** 2-4 hours  
**Priority:** P0 (Immediate)  
**Owner:** Fast Coder

### Blocker 2: Catalog API Endpoints Missing
**Issue:** `/api/v1/catalog/brands`, `/api/v1/catalog/models` return 404  
**Impact:** Vehicle selection UI shows empty dropdowns  
**Fix:**
1. Implement catalog endpoints in `backend/app/api/v1/endpoints/catalog.py`
2. Connect to `vehicle.vehicle_model_definitions` table
3. Add filtering by brand, model, year, fuel type

**Estimated Effort:** 1-2 days  
**Priority:** P0 (Immediate)  
**Owner:** Fast Coder

### Blocker 3: Expense API 500 Errors
**Issue:** `/api/v1/expenses` returns 500 Internal Server Error  
**Root Cause:** Schema mismatch between `vehicle.costs` and `vehicle.vehicle_expenses`  
**Impact:** Users cannot log maintenance costs  
**Fix:**
1. Audit database relationships in `backend/app/models/vehicle/`
2. Align SQLAlchemy models with actual table structure
3. Update API response schemas in `backend/app/schemas/`

**Estimated Effort:** 1-2 days  
**Priority:** P0 (Immediate)  
**Owner:** Fast Coder + Debugger
