main's v0.3.x event-forwarding (delivered via the event-db branch) is
content-identical to dev's, except for older version strings and the
pre-fix MLG timestamp handling that dev's 4742ed9 already superseded.
Keep dev's tree verbatim (-s ours); this only records main as merged so
the dev->main PR for v0.4.0 (mirror dual-send) merges without conflicts.
