# LittleShop Development Progress

## Project Status: ✅ BOT/UI BASELINE ESTABLISHED

### 🎯 **BOT/UI BASELINE (August 28, 2025)** ✅

#### **Complete TeleBot Integration** ✅
- **Customer Orders**: Full order history and details lookup working
- **Product Browsing**: Enhanced UI with individual product bubbles
- **Admin Authentication**: Fixed role-based authentication with proper claims
- **Bot Management**: Cleaned up development data, single active bot registration
- **Navigation Flow**: Improved UX with consistent back/menu navigation
- **Message Formatting**: Clean section headers without emojis, professional layout

#### **Technical Fixes Applied**
- **Customer Order Endpoints**: Added `/api/orders/by-customer/{customerId}/{id}` for secure customer access
- **Admin Role Claims**: Fixed missing "Admin" role claim in cookie authentication  
- **AccessDenied View**: Created missing view to prevent 500 errors on unauthorized access
- **Bot Cleanup**: Removed 16 duplicate development bot registrations, kept 1 active
- **Product Bubble UI**: Individual product messages with Quick Buy/Details buttons
- **Navigation Enhancement**: Streamlined navigation with proper menu flow

### Completed Implementation (August 20, 2025)

#### 🏗️ **Architecture**
- **Framework**: ASP.NET Core 9.0 Web API + MVC
- **Database**: SQLite with Entity Framework Core
- **Authentication**: Dual-mode (Cookie for Admin Panel + JWT for API)
- **Structure**: Clean separation between Admin Panel (MVC) and Client API (Web API)

#### 🗄️ **Database Schema** ✅
- **Tables**: Users, Categories, Products, ProductPhotos, Orders, OrderItems, CryptoPayments
- **Relationships**: Proper foreign keys and indexes
- **Enums**: ProductWeightUnit, OrderStatus, CryptoCurrency, PaymentStatus
- **Default Data**: Admin user (admin/admin) auto-seeded

#### 🔐 **Authentication System** ✅
- **Admin Panel**: Cookie-based authentication for staff users
- **Client API**: JWT authentication ready for client applications
- **Security**: PBKDF2 password hashing, proper claims-based authorization
- **Users**: Staff-only user management (no customer accounts stored)

#### 🛒 **Admin Panel (MVC)** ✅
- **Dashboard**: Overview with statistics and quick actions
- **Categories**: Full CRUD operations working
- **Products**: Full CRUD operations working with photo upload support
- **Users**: Staff user management working
- **Orders**: Order management and status tracking
- **Views**: Bootstrap-based responsive UI with proper form binding

#### 🔌 **Client API (Web API)** ✅
- **Catalog Endpoints**: 
  - `GET /api/catalog/categories` - Public category listing
  - `GET /api/catalog/products` - Public product listing
- **Order Management**:
  - `POST /api/orders` - Create orders by identity reference
  - `GET /api/orders/by-identity/{id}` - Get client orders
  - `POST /api/orders/{id}/payments` - Create crypto payments
  - `POST /api/orders/payments/webhook` - BTCPay Server webhooks

#### 💰 **Multi-Cryptocurrency Support** ✅
- **Supported Currencies**: BTC, XMR (Monero), USDT, LTC, ETH, ZEC (Zcash), DASH, DOGE
- **BTCPay Server Integration**: Complete client implementation with webhook processing
- **Privacy Design**: No customer personal data stored, identity reference only
- **Payment Workflow**: Order → Payment generation → Blockchain monitoring → Status updates

#### 📦 **Features Implemented**
- **Product Management**: Name, description, weight/units, pricing, categories, photos
- **Order Workflow**: Creation → Payment → Processing → Shipping → Tracking
- **File Upload**: Product photo management with alt text support
- **Validation**: FluentValidation for input validation, server-side model validation
- **Logging**: Comprehensive Serilog logging to console and files
- **Documentation**: Swagger API documentation with JWT authentication

### 🔧 **Technical Lessons Learned**

#### **ASP.NET Core 9.0 Specifics**
1. **Model Binding Issues**: Views need explicit model instances (`new CreateDto()`) for proper binding
2. **Form Binding**: Using explicit `name` attributes more reliable than `asp-for` helpers in some cases
3. **Area Routing**: Requires proper route configuration and area attribute on controllers
4. **View Engine**: Runtime changes to views require application restart in Production mode

#### **Entity Framework Core**
1. **SQLite Works Well**: Handles all complex relationships and transactions properly
2. **Query Splitting Warning**: Multi-include queries generate warnings but work correctly
3. **Migrations**: `EnsureCreated()` sufficient for development, migrations better for production
4. **Decimal Precision**: Proper `decimal(18,2)` and `decimal(18,8)` column types for currency

#### **Authentication Architecture**
1. **Dual Auth Schemes**: Successfully implemented both Cookie (MVC) and JWT (API) authentication
2. **Claims-Based Security**: Works well for role-based authorization policies
3. **Password Security**: PBKDF2 with 100,000 iterations provides good security
4. **Session Management**: Cookie authentication handles admin panel sessions properly

#### **BTCPay Server Integration**
1. **Version Compatibility**: BTCPay Server Client v2.0 has different API than v1.x
2. **Package Dependencies**: NBitcoin version conflicts require careful package management
3. **Privacy Focus**: Self-hosted approach eliminates third-party data sharing
4. **Webhook Processing**: Proper async handling for payment status updates

#### **Development Challenges Solved**
1. **WSL Environment**: Required CMD.exe for .NET commands, file locking issues with hot reload
2. **View Compilation**: Views require app restart in Production mode to pick up changes
3. **Form Validation**: Empty validation summaries appear due to ModelState checking
4. **Static Files**: Proper configuration needed for product photo serving

### 🚀 **Current System Status**
