This is a procedural legislative action (introducing a resolution to advance a bill) with no constitutional damage. The mechanism is listed as 'norm_erosion_only' but all drivers score 0 because: (1) This is a positive reform proposal attempting to reduce conflicts of interest, not erosion; (2) No actual policy change has occurred - only a resolution introduction; (3) The act itself would strengthen ethical norms, not erode them. The mechanism modifier is 0.0 because norm_erosion_only requires at least one non-zero driver to apply. A-score: 0. B-score is minimal (2.2) - slight media appeal for 'Congress stock trading' topic but no viral potential, no strategic timing, no intentional distraction indicators. This is routine legislative procedure with no constitutional impact and negligible hype. Clear Noise classification.
