This is routine legislative activity - the minority party proposing a bill to restrict executive authority. The mechanism is 'norm_erosion_only' but there's no actual norm erosion occurring here; this is Congress attempting to exercise its constitutional role in checking executive power on trade policy. The separation score of 2 reflects minor tension between branches, but this is normal democratic friction, not constitutional damage. The 0.3 mechanism modifier severely reduces the already-low score because norm_erosion_only without actual erosion is essentially nothing. The identical article titles (all 4 exactly the same) suggest coordinated messaging. The 'chaos and damage' framing is pure political rhetoric without substantive constitutional implications. B-score is moderate due to partisan framing and dramatic language, but this is standard legislative theater. Final A-score of 0.38 is far below the 25 threshold, and the lack of any meaningful constitutional mechanism makes this clear noise.
