Find supplier payments we made twice

The ask

Sent verbatim as the prompt. The agent works in a copy of the workspace below and sees nothing else.

A supplier says we paid them twice this year - can you find every payment we have made twice? Hannah's note says how to judge it. Save the list as duplicate_payments.csv.
