Resolving Polymarket outcomes for June 19th and 20th as 'No' because no military action transpired on those dates is exactly how it's always been done in any historical record. What happens later, like strikes on June 21st, doesn't change what already didn't happen; that's not how precedent works. If you book a band for Saturday and they don't show, the party for Saturday is off, even if a different band plays on Monday. The playbook has always separated past events from future ones, keeping things straightforward.
