Problem:
- Selecting Size then Color would reset Size selection
- Users could never get "Add to Cart" button with multiple variant types
- Each selection created a NEW list, wiping previous choices
Root Cause:
- HandleSetVariant created: new List<string> { variantName }
- This replaced all previous selections instead of accumulating
Fix:
1. Get existing selected variants from session
2. Find the variant type of newly selected variant
3. Remove any previous selection from the SAME type (allow changing choice)
4. Add the new selection
5. Save accumulated list back to session
Example behavior now:
- Select "Red" (Color) → selectedVariants = ["Red"]
- Select "Large" (Size) → selectedVariants = ["Red", "Large"] ✅
- Select "Blue" (Color) → selectedVariants = ["Blue", "Large"] ✅
- Can now confirm when all types selected

Problem:
- Product with Size + Color only required selecting 1 variant total
- User could add to cart after selecting just Size OR Color, not both
Root Cause:
- Logic checked if selectedVariants.Count == 1 for single items
- Didn't verify that all variant types were covered
Fix:
- For single items: Check that each variant type has at least one selection
- Logic: variantGroups.All(g => g.Any(v => selectedVariants.Contains(v.Name)))
- For multi-buy: Keep existing logic (total count == quantity)
Now users must select:
- Size + Color products: Must pick both Size AND Color
- Size only products: Must pick Size only
- Etc.

- OrderListMenu now shows item summary (e.g., '2x Product Name' or 'Product Name +2 more')
- FormatCart enhanced to show variant selections and multi-buy indicators
- FormatOrder enhanced to show variant names and detailed item breakdown
- Cart now clearly distinguishes between multi-buy bundles and regular items
- Order confirmations now show full product and variant details
Replaced generic GUID displays with human-readable product information for better UX.
- Changed HandleMainMenu to send new messages instead of editing
- Changed HandleBrowse to send new messages for category navigation
- Changed HandleViewCart to use SendNewCartMessage (already existed)
- Changed HandleViewOrders to send new messages for order list
- Changed HandleViewOrder to send new messages for order details
This ensures the active conversation always appears at the bottom of the chat
instead of mid-thread when users click menu buttons. Provides better UX and
natural conversation flow in Telegram.
- Added SavedShippingAddress model to store user addresses
- Added Privacy.SaveShippingAddress preference (null = not asked, true/false = user choice)
- Enhanced checkout flow to offer using saved address if available
- Ask once about saving address, respect user's choice going forward
- Automatically save/not save based on user preference in future orders
- Added menu options: Use Saved Address, Enter New Address, Save Address (Yes/No)
- Enhanced CallbackHandler with save address handlers
- Updated MessageHandler to prompt for save preference on first use
User will only be asked once about saving addresses. Account reset clears preference.
- Removed informational 'Variants: Size: X options, Color: Y options' button
- Renamed 'Add to Cart' button to 'BUY {product.Name}' for clearer UX
- Applied to both multi-buy single item and regular quantity purchase buttons
## Critical Bug Fixes
### Currency Display (£ vs $)
- Fix MenuBuilder.cs: Replace $ with £ for product prices (line 60) and order totals (line 329)
- Fix ProductCarouselService.cs: Replace $ with £ in product captions and multi-buy offers (lines 317, 325)
- Fix CallbackHandler.cs: Replace $ with £ in order confirmation message (line 800)
### Payment Amount Display Bug
- Fix MessageFormatter.cs: Remove flawed crypto detection logic (< 1.0m check)
- Bug: Order for £700 in ETH displayed as "£1.66" instead of "1.66 ETH"
- Root cause: RequiredAmount is always stored as crypto amount, not fiat
- Solution: Always display RequiredAmount with crypto symbol
- Impact: Fixes display for XMR, DOGE, LTC, and large ETH amounts
## Security: Remove PGP Encryption Feature
### Critical Security Issue Resolved
- PGP "encryption" was only Base64 encoding - NOT real encryption
- Shipping addresses stored as easily decoded text
- False sense of security for users
### Changes Made
- Mark EncryptWithPGP method as [Obsolete] in PrivacyService.cs
- Remove PGP encryption logic from order creation (LittleShopService.cs)
- Mark PGP properties as [Obsolete] in UserSession.cs models
- Disable EnablePGPEncryption feature flag in appsettings.json
- Add comments explaining feature removal
### Recommendation
Implement proper PGP encryption using BouncyCastle in future, or keep removed.
## Testing Required
- Verify all prices display with £ symbol
- Verify crypto payments show correct amount format (e.g., "1.66000000 ETH")
- Verify no PGP options appear in UI
- Test order creation without PGP encryption

**Issue**: Order creation failed because TOR proxy was being used for internal
Docker network API calls to littleshop-admin, causing DNS resolution failures.
**Root Cause**:
- All HTTP clients (BotManager, ActivityTracker, ProductCarousel) used
Socks5HttpHandler.Create() which checked Privacy:EnableTor globally
- TOR gateway can only proxy external traffic (to Telegram API)
- Internal Docker network calls to littleshop-admin failed through TOR
**Solution**:
- Updated BotManagerService to use Socks5HttpHandler.CreateDirect()
- Updated BotActivityTracker to use Socks5HttpHandler.CreateDirect()
- Updated ProductCarouselService to use Socks5HttpHandler.CreateDirect()
- TelegramBotService continues using TOR for external Telegram API
- LittleShop.Client respects LittleShop:UseTor = false setting
**Architecture**:
✅ External calls (Telegram API) → TOR for privacy
✅ Internal calls (LittleShop API) → Direct Docker network connection
**Testing**:
- Bot authenticated successfully with LittleShop API (200 OK)
- Telegram Bot API using TOR proxy (socks5://tor-gateway:9050)
- Container: 45eab050eeeca479680966b45742cf140cf7df0ed8e8ab5dc8c9e3e17739c88a

**Issue**: When users clicked "Browse Products" multiple times, Telegram API
rejected the edit request with "message is not modified" error, causing the
browse functionality to appear broken.
**Root Cause**: HandleBrowse method used EditMessageTextAsync directly, which
throws an exception when the message content is identical.
**Solution**:
- Replaced direct EditMessageTextAsync with SafeEditMessageAsync
- SafeEditMessageAsync catches ApiRequestException for "message is not modified"
- Silently handles duplicate edits without user-facing errors
**Testing**:
- Deployed to production (container: e1467c559ff6)
- Bot running as @Slukdevukbot with TOR enabled
- Categories API confirmed working (3 categories, 10 products)
