How do I rule on a duplicate cluster?

Open the cluster: every copy with company, organisation, project, status, paid and due, a preview and an open-in-Xero link, the original marked. Rule below: Confirm duplicate; Mark resolved once the void or credit note is done in Xero; or Dismiss — not a duplicate, which is sticky so the next scan will not flag the pair again. Each ruling keeps who and when and an optional note. Resolve all shown and Dismiss all shown rule on exactly what the filters show — narrow first.
