Congressional pressure on Russia ahead of Trump summit represents routine legislative oversight of executive foreign policy, not constitutional damage. Separation score (3) reflects normal checks-and-balances tension between branches on foreign policy. Mechanism='norm_erosion_only' with no concrete institutional damage yields 0.4 modifier, reducing already-low base_score of 4 to final A=1.15. This is standard legislative posturing around high-profile diplomatic events. B-score (11.49) reflects moderate media interest in Russia narrative and strategic timing around summit, but insufficient for distraction classification. Clear Noise: routine congressional activity with no measurable constitutional impact.
