This represents a direct constitutional confrontation between state and federal authority over immigration enforcement. SEPARATION scores 5: A Representative (likely state-level official misidentified) ordering state agencies to terminate federal cooperation agreements directly challenges federal supremacy in immigration matters under Article I and the Supremacy Clause. RULE_OF_LAW scores 4: This creates enforcement chaos where federal immigration law cannot be uniformly executed, undermining legal consistency. The mechanism is enforcement_action with clear state defiance of federal authority (1.25 modifier). Single_state scope (0.85) limits immediate impact but sets dangerous precedent (1.1) for other states to follow. Durability moderate (0.9) as federal government can still operate independently but loses force multiplier. B-score elevated by immigration wedge politics and state-resistance narrative but doesn't reach threshold. D-score of +4.1 indicates genuine constitutional damage exceeding political theater.
