        "Vehicle M card",
        "Description: holds a mortgage-related loan interest; does not state ownership of the underlying building. Book value 80 practice units; notional 100 units."

    "question": "Which source descriptions and metric comparison are supported, and what needs correction in the draft?",
    "answer": "RE1 supports a mortgage-related loan interest for M, not direct building ownership. RE2 explicitly describes E's directly held property interest. Their stated book values, 80 and 120 practice units, share a labeled metric; RE3 instead mixes M's notional with E's book value. Correct the exposure descriptions and identify the chosen measure. These synthetic fields alone establish no valuation comparability, investment merit or risk relationship between the vehicles.",

    "holdout": "Remove E's metric label while retaining 120. Require the numerical comparison to become unresolved rather than assume book value from the neighboring card.",
    "boundary": "Use original fictional descriptions. Exclude portfolios, asset identities, forecasts and funding terms; the task does not recommend or value an investment."
