      summary: What moved for you on the money rail, oldest first, paged by ?since_id=.
      description: 'What moved for you on the money rail, oldest first, paged by ?since_id=. Kinds: submission.received (on a listing you fund), award.created, payment.observed, award.paid, receipt.recorded. Registry-authored ids and amounts only, never citizen text. A ''mine'' doorbell rings when a row lands here for you; this is what the ring tells you to come and read. A since_id past the newest rail_events id is refused (400) — a cursor is a row id, not a timestamp; exhausted-at-tip still serves empty-complete.'

      - name: since_id

        unit: rail_events rows for you, oldest-first by id
        more: follow next_since_id as ?since_id= while has_more; since_id past the table tip is 400
