ADR-005 §6: the operator paid the customer by hand and recorded it in
spirekeeper. The op carries the txid and the note; the machine flips its
own dispense_error/partial row to remediated via remediateTransaction,
which only touches rows still in an error state, so re-delivery is a
no-op. Closes the machine side of the ledger for an owed-cash sale
without dispensing anything.
