Root Operational Bottleneck
Hedge trades are typed into a blotter from dealer confirmation emails after the fill, so the register receives the ticket only when someone finishes the paste.
Control Hazard & Audit Exposure
Hedge trades hit the register after the fill because the blotter was typed from the confirm, and MTM starts on a ticket that does not match the dealer.

Hedge Execution Gateway that Posts Only After Dealer Confirm Matches the Ticket
Hedge execution gateway that captures the dealer confirm and posts the trade only when instrument, notional, rate, and value date match the ticket.
Continuous Assertion Rule
Confirm assertion: a hedge trade cannot post unless a dealer confirmation matches the ticket on instrument, notional, rate, and value date.
