The brokerage-wide change feed: one poll instead of one per submission. Same event types, object, visibility rules and cursor contract as GET /broker/submissions/{submission_id}/events, plus submission_id on every event and, on quote_received, the quote's documents (the same entries GET /broker/submissions/{submission_id}/quotes lists; download_path is served by GET /broker/finalized-documents/{document_id}/pdf, carrier_url is carrier-hosted). documents is null on every other type, and an empty list when the quote has no document.

The end-of-stream signal is the cursor, never page length. A non-null next_cursor means more events may exist: store it and poll again with since=next_cursor until you receive a null. A page may hold fewer than limit events, or none at all, with a non-null cursor; never treat a short page as the tail. next_cursor is null only when the request proved your position is the tail of the currently-visible stream; resume later polls from your last non-null cursor. Dedupe by event id.

A machine token issued to a partner reads only the submissions that partner created.
