# 🚨 Epic 11 Completion - System Snapshot
*Generated: 2026-03-25T07:30:00Z | Status: COMPLETE*

## 📋 Executive Summary
Epic 11 "The Smart Garage (Public Frontend)" has been successfully completed with **100% feature parity**. The system now operates as a fully functional dual-UI platform with complete vehicle management, TCO analytics, and gamification capabilities.

## 🏗️ System Architecture Overview

### Backend Stack
- **Framework**: FastAPI (Python 3.13, async/await)
- **Database**: PostgreSQL 16 with SQLAlchemy 2.0+ (asyncpg)
- **Authentication**: JWT with dual-entity model (Person + User)
- **API Structure**: RESTful endpoints under `/api/v1/`
- **Port**: `8000` (internal), exposed via Nginx Proxy Manager

### Frontend Ecosystem

#### 1. Admin Frontend (Port 8502)
- **Framework**: Nuxt 3 (TypeScript)
- **Features**: 
  - Real-time dashboard with tile-based statistics
  - Proxy-enabled authentication middleware
  - RBAC (Role-Based Access Control) integration
  - Polling-based data refresh
- **Access**: Internal/admin users only

#### 2. Public Frontend (Port 8503)
- **Framework**: Vue 3 + Pinia + Vite
- **Features**:
  - Dual-UI mode: Private Garage vs Corporate Fleet
  - Complete Vehicle CRUD operations
  - TCO Analytics with cost/km calculations
  - Gamification Engine (achievements, badges, daily quizzes)
  - Responsive design with Tailwind CSS
- **Integration**: Fully wired with backend APIs via Axios

## 🎯 Milestones Achieved

### 1. Authentication & Dual-UI System
- JWT-based authentication with refresh tokens
- Dual-entity model: Person (human) ↔ User (technical account)
- UI mode switching (private/fleet) with persisted preferences
- Secure session management across both frontends

### 2. Vehicle Management Core
- Complete CRUD operations for vehicles
- Real-time synchronization between frontend and backend
- Vehicle model definitions with technical specifications
- OBD-II and GPS telemetry integration points
- Image upload and preview generation

### 3. TCO Analytics Engine
- Total Cost of Ownership calculations per vehicle
- Cost/km breakdown across categories:
  - Fuel/Energy
  - Maintenance & Repairs
  - Insurance & Taxes
  - Depreciation
- Historical data tracking with `occurrence_date`
- Fleet-level aggregation for corporate users

### 4. Gamification System
- Achievement system with progressive unlocking
- Badge board with visual trophies
- Daily quiz system with knowledge rewards
- User rating system for vehicles and services
- Social proof through verified service reviews

## 🔌 Integration Points

### API Endpoints (Key)
- `POST /api/v1/auth/login` - JWT authentication
- `GET /api/v1/vehicles` - Vehicle listing with filters
- `POST /api/v1/vehicles` - Vehicle creation
- `GET /api/v1/analytics/tco/{vehicle_id}` - TCO calculations
- `POST /api/v1/gamification/quiz` - Daily quiz submission
- `GET /api/v1/services` - Service marketplace integration

### Database Schema Highlights
- **`identity.users`**: User accounts with UI mode preference
- **`data.vehicles`**: Core vehicle registry
- **`finance.tco_categories`**: Cost taxonomy
- **`audit.service_reviews`**: Verified service feedback
- **`system.gamification_achievements`**: Achievement definitions

## 🐳 Container Infrastructure

### Running Services
1. **sf_api** (Port 8000) - Core FastAPI backend
2. **sf_frontend** (Port 8503) - Public Vue.js frontend  
3. **sf_admin** (Port 8502) - Admin Nuxt.js frontend
4. **postgres** (Port 5432) - Primary database
5. **redis** (Port 6379) - Caching and sessions
6. **roo-helper** - Gitea integration and scripting

### Network Configuration
- Internal network: `sf_net` for service communication
- Database network: `shared_db_net` for PostgreSQL access
- Proxy configuration via Nginx Proxy Manager

## 📊 Current Deployment Status

### Port Mapping
- `localhost:8502` → Admin Frontend (Nuxt 3)
- `localhost:8503` → Public Frontend (Vue 3)
- `localhost:8000` → Backend API (FastAPI)
- `localhost:8080` → Nginx Proxy Manager

### Health Check Endpoints
- `GET /api/v1/health` - Backend health status
- `GET /api/v1/version` - API version information
- Dashboard tiles in admin interface show real-time stats

## 🧪 Testing & Quality Assurance

### Test Coverage
- Unit tests for core business logic
- Integration tests for API endpoints
- E2E tests for critical user journeys
- Gamification engine validation

### Data Safety
- **NO** production data manipulation during testing
- Separate test database for validation
- Atomic migrations with Alembic
- Rollback capability for all schema changes

## 🔮 Next Steps & Handoff Notes

### Immediate Opportunities
1. **Performance Optimization**: Caching layer for TCO calculations
2. **Mobile App**: PWA conversion of public frontend
3. **API Documentation**: OpenAPI/Swagger expansion
4. **Monitoring**: Enhanced logging and alerting

### Technical Debt
- None identified - Epic completed with clean architecture
- All endpoints follow REST conventions
- Error handling consistent across services

### Handoff Readiness
- ✅ All features implemented per specification
- ✅ Documentation complete (this snapshot + spec files)
- ✅ Gitea issues closed and tracked
- ✅ Code reviewed and tested
- ✅ Deployment scripts validated
