This event represents a failed Congressional attempt to reassert war powers authority over executive military action. A=13.11: separation_of_powers scores 4.5 (0.16*4.5=0.72) as Senate rejection of War Powers Resolution reinforces executive unilateralism in military strikes, though mechanism_modifier of 0.7 applies since this is norm_erosion_only without formal institutional change. Rule_of_law scores 3.5 (0.18*3.5=0.63) as failure to enforce constitutional war powers provisions continues pattern of executive overreach. Severity multipliers: durability 1.1 (pattern reinforcement), precedent 1.2 (strengthens executive war-making norm). Federal scope with broad population impact yields 1.3 modifier. B=9.76: Layer1 (55%): outrage_bait 3 (war powers resonates with anti-interventionist constituencies), media_friendliness 3 (bipartisan angle, Massie-Khanna pairing), novelty 2 (War Powers debates recur), meme_ability 1 (procedural). Layer2 (45%): pattern_match 2 (fits anti-war narrative), mismatch 2 (bipartisan cooperation angle overstates significance of failed vote). Intentionality 3 (bipartisan_framing) yields 0.135 weight. D=+3.35 indicates modest constitutional concern exceeding hype but neither threshold met for list classification.
