## 🎯 Dual UI System: Admin vs Public Garage

### 1. Admin Dashboard (Vue 3 + Vite)
**Purpose:** System administration, fleet management, analytics  
**Status:** 75% Complete (UI built, API wiring improving)

| Component | Status | API Connection | Notes |
|-----------|--------|----------------|--------|
| **Health Monitor Tile** | ✅ Built | ✅ Connected | Now uses real API `/api/v1/admin/health-monitor` with 30s auto-refresh |
| **Financial Dashboard** | ✅ Built | ❌ Mocked | Triple wallet balances (needs `/api/v1/finance/wallets`) |
| **Gamification Control** | ✅ Built | ❌ Mocked | XP, badges, leaderboards (needs `/api/v1/gamification/*`) |
| **Service Moderation Map** | ✅ Built | ⏳ Partial | Map renders, but service data mocked |
| **User Management Table** | ✅ Built | ❌ Mocked | User list (needs `/api/v1/admin/users`) |
| **Robot Status Panel** | ✅ Built | ✅ Connected | Shows robot queue status (`/api/v1/robots/queue`) |

### 2. Public Garage (Epic 11 - Smart Garage)
**Purpose:** End-user vehicle management, service discovery  
**Status:** 50% Complete (Core components built, flows incomplete)

| Component | Status | API Connection | Notes |
|-----------|--------|----------------|--------|
| **Profile Selector** | ✅ Built | ❌ Mocked | Private Garage vs Corporate Fleet toggle |
| **Vehicle Showcase** | ✅ Built | ⏳ Partial | Shows vehicles but catalog data mocked |
| **Quick Action FAB** | ✅ Built | ⏳ Partial | Add Expense, Find Service buttons (partially wired) |
| **Daily Quiz Modal** | ✅ Built | ✅ Connected | Quiz system works (`/api/v1/gamification/quiz`) |
| **Trophy Cabinet** | ✅ Built | ❌ Mocked | Achievement display (needs `/api/v1/gamification/badges`) |
| **Business BI Dashboard** | ✅ Built | ❌ Mocked | TCO analytics (needs `/api/v1/analytics/tco`) |

## 🔌 API Wiring Status by Component

### ✅ Fully Wired Components (Real API Calls)

| Component | API Endpoint | Status | Notes |
|-----------|--------------|--------|-------|
| **Health Monitor** | `GET /api/v1/admin/health-monitor` | ✅ Working | Real system metrics with 30s auto-refresh (Ticket #134) |
| **Vehicle Addition** | `POST /api/v1/assets/vehicles` | ✅ Working | From `garageStore.js` - correctly calls backend |
| **Vehicle List** | `GET /api/v1/assets/vehicles` | ✅ Working | Fetches user's vehicles |
| **Daily Quiz** | `GET/POST /api/v1/gamification/quiz` | ✅ Working | Complete quiz flow |
| **Robot Queue** | `GET /api/v1/robots/queue` | ✅ Working | Shows pending robot tasks |
| **User Authentication** | `POST /api/v1/auth/login` | ✅ Working | JWT token flow |
| **User Profile** | `GET /api/v1/users/me` | ✅ Working | User data retrieval |

### 🔄 Partially Wired Components (Mixed Real/Mocked)

| Component | Real API | Mocked Data | Issues |
|-----------|----------|-------------|--------|
| **Service Search** | `GET /api/v1/services` | Location data | Map renders but provider data incomplete |
| **Expense Logging** | `POST /api/v1/expenses` | Cost categories | Returns 500 error (schema mismatch) |
| **Vehicle Catalog** | None | Brand/model lists | Catalog endpoints return 404 |
| **Wallet Balances** | `GET /api/v1/finance/wallets` | Transaction history | Connected but UI shows placeholder data |

### ❌ Mocked Components (No API Connection)

| Component | Mocked Data | Required API | Priority |
|-----------|-------------|--------------|----------|
| **Financial Dashboard** | Fake transactions | `/api/v1/finance/ledger` | High |
| **Gamification Leaderboard** | Fake users | `/api/v1/gamification/leaderboard` | Medium |
| **Analytics Charts** | Generated trends | `/api/v1/analytics/tco` | High |
| **User Management Table** | Sample users | `/api/v1/admin/users` | Medium |
| **Service Provider Map** | Static markers | `/api/v1/services/geospatial` | High |

## 🚨 Critical Frontend Issues

### 1. Endpoint Mismatch (Blocking Vehicle Creation)
```javascript
// Frontend expects (in some components):
`/api/v1/vehicles/register`  // 404 ERROR

// Backend actually provides:
`/api/v1/assets/vehicles`    // Correct endpoint
```

**Impact:** Users cannot add vehicles in some UI flows  
**Files Affected:** `AddVehicleModal.vue`, `QuickActionsFAB.vue`  
**Fix Required:** Update all frontend references to use correct endpoint

### 2. Hardcoded API Base URL
```javascript
// Found in multiple stores:
`${import.meta.env.VITE_API_BASE_URL || 'https://dev.servicefinder.hu'}`

// Some components still use hardcoded IP:
`http://192.168.100.43:8000/api/v1/...`
```

**Impact:** Deployment environment issues, local development broken  
**Fix Required:** Standardize on environment variable usage

### 3. Catalog Data Missing
- Vehicle brand dropdowns empty (catalog endpoints 404)
- Model selection not functional
- Year ranges static (not dynamic based on brand/model)

**Impact:** Cannot select vehicles during registration  
**Fix Required:** Implement catalog API endpoints and wire frontend

### 4. Error Handling Inconsistent
- Some components show generic "Something went wrong"
- Others have detailed error messages
- No retry logic for failed API calls
- Loading states not always shown

**Impact:** Poor user experience during API failures  
**Fix Required:** Standardized error handling component
