Resolves YES iff there is a successful AI-assisted, or autonomously AI executed, cyber attack on the real-time gross settlement system (eg Fedwire in the US, Europe's T2) of any OECD country by January 1st 2028.

The qualifying attack should result in the settlement system going offline for at least two hours, and must be the result of a deliberate attack by a third party that uses AI as a major part of the attack, or is itself an AI, according to credible reporting. Disruptions attributable to human error or internal operational failures do not count.
