Trump Makes Jabs at White House Correspondents' Dinner

This event describes routine political theater—Trump making jokes at a media dinner—with no constitutional mechanism engaged (mechanism marked norm_erosion_only but reflects rhetorical style, not institutional action). All A-score drivers are 0 as there is no impact on elections, rule of law, separation of powers, civil rights, institutional capture, corruption, or violence. The scope is narrow and federal but involves no policy or structural change. B-score is moderate due to media coverage and Trump's characteristic mocking of press, but lacks strong distraction indicators like timing correlation with major news or high strategic pivot value. This is a low-signal entertainment/media story that doesn't rise to List A or List B thresholds.
