disconnect821/orderserviceplatform

This is a Spring-based order platform for managing products and orders backed by PostgreSQL. The documented order workflow accepts a create request, validates and records an idempotency key when supplied, then processes the order while locking products to prevent stock overselling; clients can subsequently retrieve orders. Product creation and order retrieval are also documented API operations. The README is the only relationship evidence provided, so the graph omits undocumented controller/service calls and does not infer a payment workflow from the tree.
