This event represents a reversal of a deregulatory action, restoring regulatory oversight rather than undermining it. A-score is minimal (0.7) because maintaining mine safety offices actually strengthens rule of law enforcement rather than damaging constitutional norms. The policy_change mechanism applies weakly since this is a reversal that restores status quo. B-score (2.65) reflects modest media interest in the counter-narrative (Trump doing regulation rather than deregulation) but lacks viral potential or strategic timing. The narrow population scope (mining industry workers/communities) and routine administrative nature qualify this as Noise - it's a positive governance action that doesn't threaten constitutional order.
