I started each posting from a new tree and re-enrolled the series every time, which is what produced a new change-id for every revision. I've changed how I work so this cannot happen again: - one long-lived tree and one b4 branch for this series, used for all future revisions; - before every b4 send, a check that the change-id is still 20260817-qda-v2-78e2d1f10529. v5 will continue from that change-id, with the v3 and v4 postings recorded in its history.
