$20.00 refunded twice on the same capture, 2s apart

Diagnosis

AI agent (anthropic/claude-haiku-5.5)

The buyer was refunded $20.00 twice for the same $80.00 espresso order, 2 seconds apart, most likely from a retry without a duplicate-protection key. Both refunds completed, so the buyer has $40.00 back and the extra $20.00 has already left the shop's account. Nothing further goes out automatically, but the owner needs to decide whether to keep the $20.00 overpayment or ask the buyer to return it.

The duplicate refund is already completed and reversing or adding money movement is the owner's decision, so this needs the owner rather than an automatic action.

Note: Order 6GL03991ND044991H (espresso sampler, $80.00) was refunded $20.00 twice (refunds 5AK95525WH343112R and 5XA57134M1951843B, 2 seconds apart). The buyer has received $40.00 back and the order is still unshipped with $40.00 remaining on the capture. Do y
