test/orders.test.js passes on the baseline schema and fails in all 2 candidate runs. New in every candidate run, absent from the control run: SQLSTATE 22P02 (invalid_text_representation): invalid input value for enum order_status: "shipped" — statement: UPDATE orders SET status = 'shipped' WHERE id = $1 The previous application version reproducibly fails against the proposed schema, and the failure is linked to a specific schema change. test/orders.test.js: SQLSTATE 22P02 (invalid_text_representation) linked to column_type_changed:orders.status by R6 type error ↔ changed column type.
