Congressional oversight subpoena disputes are routine separation-of-powers interactions. The 'heated exchange' framing emphasizes interpersonal conflict ('shut up' quote) over substantive constitutional issues. Rule_of_law scored 1.5 for oversight function, separation 2.5 for executive-legislative tension, but mechanism_modifier 0.6 reflects norm_erosion_only with no concrete institutional damage. Severity multipliers low (0.8/0.9/0.85) as congressional spats are common and reversible. A-score 1.83 well below threshold. B-score 23.65 driven by high outrage_bait (8), media_friendliness (9), strong mismatch (8) between dramatic framing and routine oversight. Intentionality 6 for theatrical presentation. Classification: Noise - routine congressional conflict amplified through personality drama, no mechanism beyond norm erosion, A<25, multiple noise indicators present.
