Consumer banking
The doctor’s referral.
A patient pays a $300 consultation fee on her credit card. The doctor refers her to a specialist, $1,800. Different merchant. Same patient, same day. To the card network, these look like two independent transactions. The second gets declined as suspicious. The patient scrambles. Nobody is happy.
The network actually knows these are related. It just throws away the information during the 180→20 field compression. Moridain restores ten bounded signals that the bank can act on, within the existing message, within the authorization SLA.
