Money Handling Architecture:
- Store all monetary values as integer cents (€105.91 = 10591)
- Add app/utils/money.py with Money class and conversion helpers
- Add static/shared/js/money.js for frontend formatting
- Update all database models to use _cents columns (Product, Order, etc.)
- Update CSV processor to convert prices to cents on import
- Add Alembic migration for Float to Integer conversion
- Create .architecture-rules/money.yaml with 7 validation rules
- Add docs/architecture/money-handling.md documentation
Order Details Page Fixes:
- Fix customer name showing 'undefined undefined' - use flat field names
- Fix vendor info empty - add vendor_name/vendor_code to OrderDetailResponse
- Fix shipping address using wrong nested object structure
- Enrich order detail API response with vendor info
Vendor Filter Persistence Fixes:
- Fix orders.js: restoreSavedVendor now sets selectedVendor and filters
- Fix orders.js: init() only loads orders if no saved vendor to restore
- Fix marketplace-letzshop.js: restoreSavedVendor calls selectVendor()
- Fix marketplace-letzshop.js: clearVendorSelection clears TomSelect dropdown
- Align vendor selector placeholder text between pages

Problem:
- Ruff removed 'from app.core.database import Base' from models/database/base.py
- Import appeared "unused" (F401) but was actually a critical re-export
- Caused ImportError: cannot import name 'Base' at runtime
- Re-export pattern: import in one file to export from package
Solution:
1. Added F401 ignore for models/database/base.py in pyproject.toml
2. Created scripts/verify_critical_imports.py verification script
3. Integrated verification into make check and CI pipeline
4. Updated documentation with explanation
New Verification Script:
- Checks all critical re-export imports exist
- Detects import variations (parentheses, 'as' clauses)
- Handles SQLAlchemy declarative_base alternatives
- Runs as part of make check automatically
Protected Files:
- models/database/base.py - Re-exports Base for all models
- models/__init__.py - Exports Base for Alembic
- models/database/__init__.py - Exports Base from package
- All __init__.py files (already protected)
Makefile Changes:
- make verify-imports - Run import verification
- make check - Now includes verify-imports
- make ci - Includes verify-imports in pipeline
Documentation Updated:
- Code quality guide explains re-export protection
- Pre-commit workflow includes verification
- Examples of why re-exports matter
This prevents future issues where linters remove seemingly
"unused" imports that are actually critical for application structure.

- Replace black, isort, and flake8 with Ruff (all-in-one linter and formatter)
- Add comprehensive pyproject.toml configuration
- Simplify Makefile code quality targets
- Configure exclusions for venv/.venv in pyproject.toml
- Auto-fix 1,359 linting issues across codebase
Benefits:
- Much faster builds (Ruff is written in Rust)
- Single tool replaces multiple tools
- More comprehensive rule set (UP, B, C4, SIM, PIE, RET, Q)
- All configuration centralized in pyproject.toml
- Better import sorting and formatting consistency

- Standardize quote style (single to double quotes)
- Reorder and group imports alphabetically
- Fix line breaks and indentation for consistency
- Apply PEP 8 formatting standards
Also updated Makefile to exclude both venv and .venv from code quality checks.

Implemented a complete shopping cart system with database persistence,
replacing the previous stub implementation. The cart now properly stores
items across sessions and follows the project's architecture patterns.
Database Changes:
- Add cart_items table with vendor_id, session_id, product_id, quantity, price_at_add
- Create unique constraint to prevent duplicate items per session
- Add indexes for session lookups and old cart cleanup
- Run migration a2064e1dfcd4 to create cart_items table
New Models & Schemas:
- models/database/cart.py: CartItem SQLAlchemy model with relationships
- models/schema/cart.py: Pydantic schemas for requests/responses
* AddToCartRequest, UpdateCartItemRequest
* CartResponse, CartItemResponse, CartOperationResponse, ClearCartResponse
Exception Handling:
- app/exceptions/cart.py: Cart-specific exceptions following project patterns
* CartItemNotFoundException - item not found in cart
* InsufficientInventoryForCartException - not enough inventory for cart operation
* InvalidCartQuantityException - invalid quantity validation
* CartValidationException - general cart validation
* EmptyCartException - operations on empty cart
* ProductNotAvailableForCartException - product unavailable
- Updated app/exceptions/__init__.py to export cart exceptions
Service Layer:
- Implement cart_service.get_cart() - fetch cart from database with totals
- Implement cart_service.add_to_cart() - create or update cart items with inventory checks
- Implement cart_service.update_cart_item() - update quantity with validation
- Implement cart_service.remove_from_cart() - delete cart item
- Implement cart_service.clear_cart() - remove all items for session
- Replace generic exceptions with cart-specific ones
- Fix InsufficientInventoryException usage (was using wrong parameters)
API Layer:
- Update app/api/v1/shop/cart.py to use Pydantic schemas
- Add response_model declarations to all endpoints
- Add return type hints for type safety
- Convert service dict responses to Pydantic models
Features:
- Cart items persist in database across server restarts
- Inventory validation before adding/updating items
- Price captured at time of adding to cart
- Duplicate items update quantity instead of creating new entries
- Full CRUD operations with proper error handling
- Type-safe API with auto-generated OpenAPI documentation
