If today's orders.csv has three rows with amounts 100, 250, 75 and the script runs once, what does the final print(f"sent total ${total:,.2f}, archived {src.name}") print? Use the format the f-string produces (total = 100 + 250 + 75 = 425.00, filename = <today>.csv where today is 2026-05-28). Type the exact line.
