Presidential attendance at G7 summit is routine diplomatic engagement with no constitutional implications. No drivers triggered: no election interference, no rule of law violations, no separation of powers issues, no civil rights impacts, no institutional capture, no corruption indicators, no violence. A-score=0. B-score minimal (2.2): slight media coverage (media_friendliness:3) as standard news, minimal outrage potential (1). This is standard presidential foreign policy function. Mechanism unknown but irrelevant as no constitutional damage pathway exists. International scope with narrow population impact confirms routine diplomatic event. Clear noise: routine governmental function, no constitutional damage mechanism, A<25, B<25.
