You are right, and I'm not going to call it data loss again. 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.
