Canary xqqwdq/moral-salmon = vr1-dc0-storage-04 (a storage node, least
central of the ten). Office1 23 -> 22; it re-enlisted into the new region
carrying boot MAC 52:54:00:2b:ed:ab -- the machine that arrived is the
machine that left. system_id AND hostname are both re-minted
(xqqwdq -> 6q4syf, moral-salmon -> civil-bug), so the boot MAC is the only
stable key; the pre-delete snapshot records it as the identity.

MEASURED ORDERING, not the obvious one: a freshly-enlisted machine has no
power config, so MAAS cannot power-cycle it and cannot drive commissioning.
delete -> power on BY HAND via virsh -> self-enlist -> SET POWER -> abort ->
commission. Skipping the power step wedges the machine in Commissioning
producing zero events, because the enlistment ephemeral powers the node off
and nothing can bring it back.

maas-node-power.sh already supports the split the migration needs: VIRSH_URI
enumerates from voffice1 over the transit /30 while the positional address
stores what the REGION dials over metal-admin. Result was a real
query-power-state, proving the region drives the rack's libvirt with the
SEC-012 key in its snap.

Found: the per-node serial log stopped capturing on 2026-07-21 while the
domain XML still configures append-mode logging. It contains a complete,
plausible boot that I read as current and reported as fact before checking
the mtime. An append log that silently stopped appending returns confident,
well-formed, wrong evidence. Logged, not actioned.
