This event represents standard diplomatic protocol with zero constitutional damage. China sending an official to a U.S. presidential inauguration is routine international relations practice, not a constitutional threat. No mechanism identified for constitutional harm. The A-score is 0 across all drivers as this involves foreign diplomatic gestures with no impact on U.S. constitutional structures, rule of law, elections, civil rights, or institutional capture. The B-score is low (8.02) reflecting modest media interest in the diplomatic gesture amid U.S.-China tensions, but insufficient to reach distraction thresholds. This is clearly noise: routine diplomatic activity with no constitutional implications and minimal distraction potential.
