This is routine foreign policy action with minimal constitutional implications. The sanctions represent standard executive branch foreign policy tools under existing statutory authority (IEEPA, Venezuela sanctions framework). Rule_of_law driver scores 1/5 only because it involves unilateral executive action in foreign affairs, but this is well-established presidential authority with no domestic constitutional tension. The action affects a narrow population (4 firms, 4 tankers) in international scope with no mechanism challenging US constitutional structures. Severity multipliers reflect that sanctions are moderately durable but reversible by future administrations (0.9) with weak precedent value (0.8) as this continues established Venezuela policy dating to 2019. Mechanism modifier 1.15 for policy_change, scope modifier 0.7 for international. Base score of 1 yields final A-score of 0.52. B-score reflects minimal hype: low outrage (routine sanctions), no meme potential, slight novelty (specific targets), moderate media coverage (7 articles, standard reporting). Layer 2 shows minimal strategic manipulation. Final B-score 3.1. With A<25, no constitutional mechanism, and routine foreign policy indicators, this clearly qualifies as Noise.
