To make revisions in title 51, United States Code, as necessary to keep the title current, and to make technical amendments to improve the United States Code.

Every bill carries a core record (title, sponsor, latest action) that Concord fetches up front. The detailed sections — cosponsors, action history, subjects, titles, and summaries — live behind separate Congress.gov endpoints, so they're fetched on demand rather than for all 50,000+ bills at once. Until a bill has been enriched, those sections stay empty.
