What cleanup should focus on first
Start by identifying obvious duplicate patterns, missing core identifiers, and places where household relationships are inconsistent across records.
Early cleanup should make review easier, not create a second wave of hidden record changes that no one can explain later.
What should not be improvised
Do not merge records casually when the overlap is uncertain, the household meaning is unclear, or the change could hide pastoral or financial history.
If your team cannot explain why two records should become one, the safest next step is review, not cleanup theater.
