How to prioritize 3,000 pre-filtered duplicate detector results when it only sorts alphabetically, includes inactives, and Lists can't filter on 'is duplicate'?

Answer

Use each pair's created-when/where info to separate migration debt from live duplicates, cross-reference the alphabetical detector against targeted Lists (active givers, background-checked volunteers, active check-in families) to triage, and build a post-migration-date List to quantify ongoing duplicate creation.
