      "description": "Evidence pack for a bank-statement parallel run, where a treasury receives the same period twice: once as a Swift MT9xx statement it maps itself, and once as the bank's native camt.053. Stage 1 maps the MT leg to a camt-shaped object with a fidelity report and the 60F + sum(61) = 62F balance check. Stage 2 classifies the native camt.053 leg by BkTxCd and checks the OPBD + sum(movements) = CLBD balance equation. Stage 3 takes declared record counts and control totals for both legs and checks count completeness, value completeness against a declared tolerance, and aggregate-versus-partition consistency. Both legs are DECLARED inputs: the pack reads no bank connection and fetches no statement, so it evidences whether the two legs agree, never that either leg is correct. A run that cannot establish agreement reports that as its own state rather than defaulting to a pass.",
