    "title": "An authorization amount is not a measured quantity or a finalized shop line",

    "question": "What final quantity and total are documented for S, and should the duplicate authorization or S2's equal shop amount be added?",
    "answer": "FPX2 supports eight Q-units on S's measured line and a combined finalized amount of 28 practice currency units from 24 plus four. FPX1's 40 is an authorization ceiling; its duplicate event key supplies neither a second authorization nor a finalized charge. FPX3 belongs to S2 and cannot be joined by equal shop amount. Preserve quantity, authorization and each finalized line separately rather than sum all receipt-like numbers.",
