Logs the operator-requested Roosevelt-delta observation from the phase-03
core-verify thread. D-134 pins node statics (per-role octet bands) and the VIP
band (.50-.99 reserved); the OpenStack control plane runs in Juju LXD containers
whose addresses are NOT pinned -- MEASURED 2026-08-06 as MAAS device interfaces in
mode=static but auto-picked from the .100-.200 pool independently per subnet, so
container octets float across planes and are not redeploy-stable. Harmless in VR1
(clients use VIPs; certs reissue to cover whatever a unit holds). Roosevelt-delta:
a bare-metal build wanting predictable container addressing would add a
per-container static reservation (a "container carve"). GA-R3: observation, no new
D-number -- annotated onto D-134.
