Presidential call for ceasefire is standard foreign policy rhetoric with minimal constitutional impact. Separation score of 1 reflects executive foreign policy role but no actual mechanism of constitutional damage present - just a statement. Policy_change mechanism doesn't apply as this is aspirational rhetoric, not implemented policy. International scope with narrow population (diplomatic actors) limits domestic constitutional relevance. High B-score (22.28) driven by media-friendly timing post-Zelenskyy meeting and narrative positioning, but falls short of List B threshold. Clear noise event: presidential foreign policy statement generating headlines without constitutional mechanism.
