    "question": "What full-period delivery is supported, and should the subset report be added or substituted to close the booking difference?",
    "answer": "MB2 supports 95 adjusted delivery units for P over days 1–10. Against MB1's committed 100, a five-unit difference remains unevidenced in this packet. MB3's 60 covers days 6–10 already inside the full-period scope, so adding it would double-count and substituting it would shorten coverage. Keep commitment, delivery, adjustment and reporting window separate without inventing reconciliation or a payment outcome.",
