    "title": "A period shipment total cannot be allocated to an unnamed lot",
    "context": "A fictional gypsum ledger uses practice mass units. It distinguishes period production from outbound shipments and deliberately leaves one shipment's lot identity unresolved.",
    "records": [
      [
        "GY1",
        "Monthly summary",

    "question": "How much outbound material is directly linked to G-A, and can the packet establish G-A's total production or ending inventory?",
    "answer": "GY2 directly links 7 outbound units to G-A. GY1 and GY3 reconcile the period's total outbound quantity as 7+11=18, but the unassigned 11 cannot be attributed to G-A. The 30-unit production summary covers period M rather than that lot. Without lot-level production and inventory records, G-A's total production and ending balance remain unknown.",
