reg-watch-changes: Incremental feed of US Federal Register rules, proposed rules, and notices published since a date you supply. Built for scheduled polling: pass since=YYYY-MM-DD and get only documents you have not seen, each with its document number, agency, type, date, and direct link, plus nextSince for your next poll. Dedupe on documentNumber. Fails closed if the source is unreachable, so an empty feed always means no new rules. Query: topic (required), since (optional).
