HR 2140 Re-checks Congress.gov for new actions and updates the bill's status, and fills in any sponsors, committees, or related bills that are missing. It does not re-pull sponsors/cosponsors/committees/related — those rarely change — and it skips all work if nothing has changed upstream, so it's cheap to click.
