Death threats against a Representative are serious and contribute to violence (3.5) and civil_rights erosion (2.0), with minor rule_of_law implications (1.5). However, mechanism is norm_erosion_only (0.6 modifier), scope is narrow federal (0.85), and severity shows limited durability/precedent (0.855 combined). Base 7.0 * 0.6 * 0.85 * 0.855 = 3.22. B-score driven by high outrage_bait (8) and media_friendliness (7) in partisan controversy context, with Layer 2 pattern_match (7) to ongoing culture war narratives. Intentionality moderate (6) given framing. Final B=15.10. Delta=-11.88 suggests distraction, but A<25 threshold and multiple noise indicators (norm_erosion_only mechanism, narrow scope, insufficient constitutional mechanism detail, single-source) trigger Noise classification. This represents localized harassment incident amplified through partisan lens without systemic constitutional damage pathway.
