 "title": "SAR narrative desk: an investigator draft with a wrong total, a shifted date and an invented wire",
 "about": "A synthetic structuring case (a transactions CSV, KYC and alert fields, investigator notes) and an investigator draft with citations, in which three things were planted: a total $1,000 too high, a date moved by two days, and a $25,000 wire that is not in the ledger. Check mode makes no drafting call: every number is recomputed from the cited rows and each sentence is judged against what it cites. The three planted sentences must be held, the right figures named, the screen must find structuring, the filing copy must drop the held sentences and the citations, and the signed report must verify and catch a changed status.",
