Move actual code implementations into module directories: - orders: 5 services, 4 models, order/invoice schemas - inventory: 3 services, 2 models, 30+ schemas - customers: 3 services, 2 models, customer schemas - messaging: 3 services, 2 models, message/notification schemas - monitoring: background_tasks_service - marketplace: 5+ services including letzshop submodule - dev_tools: code_quality_service, test_runner_service - billing: billing_service - contracts: definition.py Legacy files in app/services/, models/database/, models/schema/ now re-export from canonical module locations for backwards compatibility. Architecture validator passes with 0 errors. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Inventory model for tracking stock at warehouse/bin locations.
|
|
|
|
Each entry represents a quantity of a product at a specific bin location
|
|
within a warehouse. Products can be scattered across multiple bins.
|
|
|
|
Example:
|
|
Warehouse: "strassen"
|
|
Bin: "SA-10-02"
|
|
Product: GTIN 4007817144145
|
|
Quantity: 3
