OptionalerrorVerbatim failure, surfaced to the operator, when outcome is FAILED.
REGISTERED: the vendor id was created and stored. ACTION_REQUIRED: the
instrument lacks what the vendor needs and was set ACTION_REQUIRED.
SKIPPED: withheld for a reason the customer cannot fix (a legacy row
with no resolved bank); not retried. FAILED: the vendor refused it; left
for an operator, and a re-run tries again. A vendor fault throws instead.
