Why an agent can trust this route.
Sonar evidence is advisory. Paid delivery is shown as verified only when paid probes are available; otherwise route estimates use the unpaid handshake as a clearly labeled proxy.
Observed outcomes
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).
