    "title": "An itemized credit must be applied once, while a dispute remains a separate event",
    "context": "An original synthetic ledger uses arbitrary units and no actual debtor, account, notice or collection action. Its arithmetic does not establish that any debt is owed or collectible.",
    "records": [
      [
        "DV1",
        "Practice ledger",
        "Opening amount 100 units; dated credit C1 of 20. No other adjustments under the fixture's stated rule."
      ],
      [
        "DV2",
        "Notice comparisons",
        "Notice N1 reports 80 and itemizes C1 once. Notice N2 reports 60 because it subtracts the same C1 twice; same ledger reference."

        "DV3",
        "Dispute event",
        "Original mock dispute D references N1, date day 5. No later resolution or compliance decision supplied."
      ]
    ],
    "question": "Which notice reconciles to the stated ledger, what error appears in the other, and what status must the summary preserve?",
    "answer": "DV1 supports 100 minus the single 20-unit credit, or 80 practice units, matching N1 in DV2. N2 subtracts C1 twice and understates that arithmetic result by 20. DV3 separately records a dispute of N1 and supplies no resolution. Preserve the dispute even though N1's numbers reconcile; arithmetic agreement does not determine validity, liability, collectibility or what action a collector may lawfully take.",
