Timeline
Every typed-graph event involving this entity, newest first. Each row is one edge in the influence graph; the inline strip under the row shows the counterpart's own context (a bill's latest action, a hearing's chamber + date, a filing's form type + filed date, a clip's source + excerpt) so the timeline reads like a Wikipedia citation rail.
