Extended National Guard deployment in DC represents significant constitutional damage across multiple vectors. ELECTION (3.5): Militarized capital creates intimidation environment affecting democratic processes and peaceful transfer norms. RULE_OF_LAW (4.0): Prolonged military presence without clear emergency justification erodes civilian governance principles and Posse Comitatus norms. SEPARATION (4.5): Executive branch using military forces in capital without legislative oversight challenges separation of powers and federalism. CIVIL_RIGHTS (3.0): Military presence in civilian spaces creates chilling effects on assembly, protest, and free movement. Severity multipliers: durability 1.1 (multi-month deployment), precedent 1.2 (normalizes capital militarization). Mechanism modifier 1.25 for enforcement_action with military forces. Scope 1.3 for federal capital symbolism. B-score moderate: outrage_bait high (military occupation imagery), media_friendliness high (visual/symbolic), but novelty lower (post-J6 deployments occurred). Layer 2 elevated by mismatch (peacetime deployment) and pattern_match (authoritarian aesthetics). Intentionality 8/15 for deliberate extended timeline. Delta +50.89 clearly exceeds +10 threshold with A>=25, placing on List A.
