    "title": "The selected date matters more than the newest file timestamp",

    "answer": "RA1 supports label A for U1 on day 15, before its signed rider takes effect, and B on day 22, after day 20. RA2's newer saved timestamp does not supply signature or authority for C. RA3 concerns U2 despite its similar rider title. Preserve unit, effective date and authorization rather than choosing a document solely by filename or latest modification time.",
