`history.rollback.preview`

Check whether one change from History can be rolled back and exactly what rolling it back would do, record by record: the values it puts back, what is already back, and what blocks it (a later edit, a deleted record, a closed period). For a statement or CSV import it previews undoing every line that can be undone. Returns previewFingerprint for history.rollback.apply. Nothing changes.
