Review Summary
Your solution has a critical test failure - the automated test explicitly checks that Order updates should NOT be placed inside the transaction block. Currently, your code wraps all operations (including Order creation) in a single transaction, but the task requirements expect Order creation to happen outside the transaction while only balance/inventory operations remain atomic. Move the INSERT INTO Orders statement outside the START TRANSACTION...COMMIT block to fix this issue. The transaction should only contain the OrderItems insert and the Products warehouse update to maintain atomicity for those specific operations.

The comment indicates some data should be created outside the transaction, but all operations here need to be atomic. Either update the comment to explain why everything is in the transaction, or clarify what data the original author intended to place outside.

Review Summary
Your solution correctly implements all task requirements. The INSERT INTO Orders statement is properly placed outside the transaction block, while the OrderItems insert and Products warehouse update are correctly wrapped in the atomic START TRANSACTION...COMMIT block. The database schema in create-database.sql properly defines all required tables (Products, Customers, Orders, OrderItems), and the task.sql file contains the correct implementation with the order created for customer ID 1 on date 2023-01-01 containing one item with decremented warehouse stock. All automated tests are passing with no failures reported.
