# An OrderPayout is only created when order status changes to a final state. See order model.
# In a finalized order, a single OP is created for the vendor.
# All expired orders have a single OP regardless of whether there is anything to refund. It was simpler to code this way.
# For partial refunds, the order will have two associated OrderPayouts - a buyer and a vendor OrderPayout.
# Users can alter the payout address any time before it has been paid, even if set automatically with the address defined in account settings.
# For security, considered making it immutable once set but not really worth it because the window of time from being finalized to being paid
# is small so attacker (phisher) won't have many order payouts available to change.
