This represents routine judicial oversight blocking executive regulatory changes - a normal function of separation of powers. The judge's temporary halt prevents ACA rollback, scoring moderate on rule_of_law (3) as it enforces existing statutory framework, separation (4) as judiciary checks executive, and civil_rights (3) for healthcare access implications. However, the mechanism_modifier is 0.6 because this is a temporary injunction (not final ruling) and represents standard judicial review rather than constitutional crisis. The event is temporary (durability 0.9), likely reversible through appeals (0.85), and follows established precedent for ACA litigation (0.95). B-score is elevated due to Obamacare's high media friendliness (7) and outrage potential (5) as perennial wedge issue, plus pattern_match (6) to ongoing ACA battles. Despite both scores being below 25, this is classified as Noise because it represents routine judicial process with temporary effect, no novel constitutional mechanism, and follows predictable ACA litigation patterns that have occurred dozens of times since 2010.
