State-federal cooperation on immigration enforcement represents routine policy alignment rather than constitutional crisis. A-score 11.2: civil_rights (2.5) for immigration enforcement impacts, rule_of_law (2.5) for federalism dynamics, separation (2.0) for state-federal coordination. Policy_change mechanism adds 15% modifier, single_state scope reduces by 15%. Severity near baseline - state cooperation is reversible, limited precedent for federal system. B-score 19.5: Layer 1 (11.0/20) - high media_friendliness (7) for Trump-Texas narrative, moderate outrage_bait (6), low novelty (3) as state cooperation is expected. Layer 2 (8.1/18) - pattern_match (6) fits immigration narrative, timing (5) during administration transition, moderate intentionality (7/15) for political messaging. Both scores below 25 threshold, mechanism present but routine, clear noise indicators.
