The predicted unaided answer accepts it as the defect's coverage and closes the ticket, and if it writes any test at all it writes one only against the current module - which passes trivially. Neither of the developer's two cases can fail on the pre-fix code: the first asserts a status field, the second uses two DIFFERENT idempotency keys, and the archived copy at 61ab904 creates two orders for two keys exactly as the fixed code does. A test that would have been green before the fix is not coverage of this defect. The discriminating output rejects that test explicitly, writes a reproduction using the SAME key twice, and shows it failing against src/archive/orders.61ab904.js while passing against src/orders.js.",
