Risk-change history for one address in a pool, newest first, for compliance review. Same record shape as the pool-level feed: kind=SCAN for a change found by a scan, ENROLL for the enrollment baseline, REBASELINE for a baseline move. Records appear a couple of minutes after detection, so a just-enrolled address may return an empty page briefly. Removed members' history is included; memberDeleted reports the member's current state. Paginated: pageSize defaults to 50, max 1000; pass the nextPageToken from the previous response as pageToken. An empty nextPageToken means no more pages.
