A finance operations team is mapping sources before a payroll exception analysis. Visible tabs: Exception Register: headers show exception count, payroll value, employee group, region; date range weeks 21-26 of 2026; Review Eligibility Policy: defines exception-count cutoff, value threshold, employee-group exclusion; date range rule version effective during the same operating period; Payroll Calendar: shows cycle close date, processing window, region; date range capacity listed by upcoming week; Definitions and Units: explains metric units, grouping grain, and exclusion codes; date range same as rule version; Benefits FAQ: contains benefit topic, employee audience, revision date; date range annual or narrative summary from a broader grain. The exhibit's task is to identify the region requiring immediate review and the tab needed to verify eligibility, but the sources differ in timing or granularity. Which triage note best prevents the analyst from combining mismatched sources?
