Tariff announcement scores moderate on constitutional damage (A=19.3) primarily through economic capture (3.0), election interference via economic manipulation (2.5), and separation of powers concerns around executive trade authority (2.5). Policy_change mechanism adds 15% modifier, international scope adds 25%. However, A-score remains below threshold of 25. B-score (22.7) driven by high media friendliness (7.5) and outrage potential (6.5) of trade war rhetoric, plus strategic timing and narrative control indicators (intentionality=8). Despite elevated B-score approaching threshold, the event lacks sufficient constitutional mechanism detail and represents routine exercise of existing executive trade powers. Single vague article ('Trump new big tariff move') provides insufficient specificity. Pattern matches previous tariff announcements without novel constitutional dimension. Classification: Noise due to A<25, routine policy nature, and insufficient evidence of extraordinary constitutional impact beyond normal trade policy discretion.
