Prepared a rollback-safe remediation plan and refreshed the dry-run artifact for the bi-weekly client-call family. May 2 baseline: 6,390 total rows, 3,950 open, 2,504 overdue open, 424 duplicate matters, 230 same-due-date groups, 194 mixed-due-date groups, and 692 proposed duplicate-close rows. Same-due-date cleanup is the safer first live lane. Mixed-due-date groups still need a survivor policy choice.
