What it means
The same event was exported more than once. Extra copies are listed as exact_duplicate_event in row_decisions and the event is counted once.
What to do: Nothing, unless the copies are distinct events. Then export an event ID.
Decide whether the copies are the same event
If the same exported event appears twice, repeating the export should not double the analytical event count. The extra copies are recorded as exact_duplicate_event in row_decisions, while the event is counted once.
Inspect the event identity
Compare the flagged rows with the original system. If they are repeated exports of the same event, consolidation matches the evidence. If they represent two real events that happen to have identical visible values, export a source event ID that distinguishes them.
The claims example maps event_id to event_ref through field_map. After changing an export, validate it and review the event count for a known claim. Do not assume that repeated text alone proves either duplication or two separate events.
