**Root Cause**: EF Core Include() was not properly materializing the Variants navigation
property despite correct SQL JOIN generation.
**Solution**: Load variants separately and manually group by ProductId for DTO mapping.
This bypasses EF Core's navigation property fixup issues.

AsNoTracking() prevents EF Core from properly wiring up navigation properties.
Removing it allows Include() to populate Variants collection correctly.

**Problem**: EF Core was not materializing Variants navigation property when using
.Select() projection directly in the query. The .Include() was being ignored.
**Solution**: Changed approach to:
1. Load entities with .Include() + .ToListAsync() first
2. Then project to DTO with in-memory .Select()
This ensures navigation properties are fully loaded before mapping to DTOs.
**Impact**: Variants will now properly appear in all product API responses.

Critical bug where ProductVariants were never loaded from database.
**Problem:**
`.Include(p => p.Variants.Where(v => v.IsActive))` syntax was NOT
generating SQL JOIN statements in EF Core 9.0, causing all products
to return empty variants array even when variants exist in database.
**Solution:**
- Changed to simple `.Include(p => p.Variants)`
- Filtering still happens in DTO mapping (Select statement)
- Only IsActive variants are returned to API consumers
**Impact:**
- TeleBot can now display product variants with selection UI
- Variant pricing and stock levels now visible to customers
- Multi-variant products (e.g., Size/Color) now functional
**Test Case:**
Product 131cc3ad-07f4-4ec9-89ca-b05a0b4cfb41 has 7 variants:
- Size: Small, Medium, Large, XL
- Color: Black, White, Navy Blue
These will now appear in API responses and TeleBot UI.

Critical fixes to ensure smooth deployments and prevent future outages:
**docker-compose.yml:**
- Fixed image name: littleshop:latest → localhost:5000/littleshop:latest
- Fixed subnet: 172.21.0.0/16 → 172.23.0.0/16 (matches production)
- Fixed environment: Production → Development (matches current production)
**.gitlab-ci.yml:**
- Fixed TeleBot API URL: http://littleshop-admin:8080 → http://littleshop:5000
- Removed duplicate network flag (was causing issues)
- Added explicit network connection command for littleshop_littleshop-network
- Ensures TeleBot can communicate with LittleShop API on deployment
**CLAUDE.md:**
- Documented October 4, 2025 incident and recovery
- Added comprehensive deployment best practices
- Documented pre-deployment checklist
- Added manual deployment commands for emergencies
- Documented network architecture and container configuration
**Root Cause of Previous Failure:**
TeleBot was trying to connect to non-existent hostname "littleshop-admin"
on wrong network, causing authentication failures and data unavailability.
**Verification:**
All changes tested in production and confirmed working. TeleBot now
successfully authenticates and communicates with LittleShop API.

Prevents future deployment failures by automatically applying database
schema migrations during deployment process.
Changes:
- Added migration step that runs AFTER stopping containers
- Automatically detects .sql files in LittleShop/Migrations/
- Creates timestamped backup before applying each migration
- Applies migrations using sqlite3 in Alpine container
- Properly handles volume mounting for littleshop_littleshop_data
This prevents issues like the October 4 incident where ProductVariant
schema changes were deployed without updating the database, causing
complete system outage.
Migration workflow:
1. Stop all containers
2. Check for migration files
3. Create database backup
4. Apply migrations
5. Start containers with updated schema

Critical fix for production deployment issue where code changes were
deployed without corresponding database schema updates.
Changes:
- Add Price column to ProductVariants table (decimal 18,2, nullable)
- Add ProductVariantId column to OrderItems table (TEXT, nullable)
- Add index on OrderItems.ProductVariantId for query performance
This migration was manually applied to production on 2025-10-04 to
resolve "no such column: p2.Price" errors that broke the product
catalog API.
Future deployments must include database migration steps in CI/CD.

Added Price override input field to the JavaScript variant collection editor on the product Edit page.
**Changes:**
- Added Price input field (with £ symbol) in variant details section
- Updated serialization to save Price to VariantsJson
- Excluded Price from variant label generation
- Updated button text: "Price, Stock & Weight Details"
**Location:**
Product Edit > Variants Collection > Toggle Details > Price Override
Now variant prices can be set through BOTH methods:
1. Individual variant management (CreateVariant/EditVariant)
2. Bulk variant collection editor (product Edit page)

Enables individual variants to have their own prices, overriding the base product price.
**Database Changes:**
- Added Price (decimal?, nullable) to ProductVariants table
- Added ProductVariantId to OrderItems table with foreign key relationship
- Created index on OrderItems.ProductVariantId for performance
**API Changes:**
- ProductVariantDto: Added Price field
- CreateProductVariantDto: Added Price field with validation
- UpdateProductVariantDto: Added Price field
- OrderItemDto: Added ProductVariantId and ProductVariantName
- CreateOrderItemDto: Added ProductVariantId
**Business Logic:**
- OrderService: Variant price overrides base price (but multi-buy takes precedence)
- ProductService: All variant CRUD operations support Price field
**Admin UI:**
- CreateVariant: Price input with £ symbol and base price placeholder
- EditVariant: Price editing with £ symbol
- ProductVariants list: Shows variant price or "(base)" indicator
**Client Library:**
- Updated all DTOs to match server-side changes
- Full support for variant pricing in order creation
**Migration:**
- EF Core migration: 20251003173458_AddVariantPricing
- Backward compatible: NULL values supported for existing data
**Use Case:**
Products with size/color variants can now have different prices:
- Small T-shirt: £15.00 (variant override)
- Medium T-shirt: £18.00 (uses base price)
- Large T-shirt: £20.00 (variant override)

## Issue
Order creation failing with 400 BadRequest when using CustomerInfo (Telegram users).
Validator required IdentityReference to always be populated, but it's null when using CustomerInfo.
## Root Cause
CreateOrderDtoValidator.cs:10-12 enforced NotEmpty() on IdentityReference unconditionally.
TeleBot sends CustomerInfo for identified users, leaving IdentityReference null.
## Solution
Updated validator to accept EITHER IdentityReference OR CustomerInfo:
- New rule: At least one must be provided
- IdentityReference validation only applies when it's provided (.When() condition)
- Maintains backward compatibility with anonymous orders
## Impact
✅ Telegram bot orders can now be created successfully
✅ Anonymous orders still require IdentityReference
✅ Proper validation error messages for both scenarios
## Testing Required
- Create order via Telegram bot (with CustomerInfo)
- Create anonymous order (with IdentityReference)
- Verify both scenarios work correctly

## Issue
Previous fix enabled LittleShop__UseTor=true, which tried to route internal
Docker API calls through Tor. Tor correctly rejected these private addresses.
## Root Cause
Two separate Tor configuration flags exist:
1. Privacy__EnableTor - Controls Telegram Bot API calls (external, public)
2. LittleShop__UseTor - Controls LittleShop API calls (internal, private)
## Solution
- Set LittleShop__UseTor=false (internal calls direct - no Tor)
- Set Privacy__EnableTor=true (Telegram API calls via Tor)
## Impact
✅ Telegram Bot API calls now route through Tor (privacy protected)
✅ Internal API calls go direct (no Tor rejection errors)
✅ Proper separation of concerns
## Technical Details
TelegramBotService.cs:77 checks Privacy:EnableTor
Program.cs:63 checks LittleShop:UseTor
These control different HTTP clients for different purposes.

## Issue
TeleBot was bypassing Tor gateway despite infrastructure being available.
## Root Cause
Deployment configuration explicitly disabled Tor:
- LittleShop__UseTor=false (line 118)
## Fix
Changed deployment configuration to enable Tor routing:
- LittleShop__UseTor=true
## Impact
✅ All Telegram API calls now route through Tor network
✅ Bot's real IP hidden from Telegram servers
✅ Enhanced privacy protection
⚠️ Slight latency increase due to Tor overhead
## Verification Required
Monitor tor-gateway logs after deployment to confirm traffic routing.

## 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**: Edit category form not displaying existing values and not updating
- Form fields were empty when loading edit page
- Submitting changes had no effect on the category
**Root Cause**:
- Edit view used asp-for helpers which don't bind properly in production

- Changed from asp-for helpers to explicit name/id attributes
- Added value="@Model.Name" to populate name input
- Added @Model.Description between textarea tags
- Changed checkbox to @(Model.IsActive ? "checked" : "")
- Matches the working pattern from Create.cshtml
