Operator: 'Commission and process all the listed tasks.' Four gated
mutations, sequenced deliberately.

MAC adoption FIRST, while the VMs were idle -- commissioning power-cycles
them and an in-place domain update must not race that. Both roots 0 add /
1 change / 0 destroy with zero creates and destroys; then MAC drift 0 across
all 20 nodes and both roots re-plan 'No changes'. The pins are now real in
state: until this apply the config asserted them but state did not record
them, so they protected nothing.

Both controllers commissioned on the DEFAULT path -- deliberately not
skip_networking=1, since unlike the storage nodes they had no configuration
to preserve. Both New -> Ready in ~200s. Power control was the only thing
missing, which confirms the earlier diagnosis by measurement.

All ruled tags created and applied, every write read back. dc0 created all
four; dc1 correctly reused the three global role tags and created only
juju-controller-vr1-dc1. Twenty nodes tagged.

Independently verified from MAAS rather than from script output: fleet 22 =
20 Ready + 2 Deployed, no New remaining; control 6 / compute 4 / storage 8 /
juju-controller-vr1-dc0 1 / juju-controller-vr1-dc1 1 / openstack-vr1-dcN 9
each. check PASSES on both DCs.

THE STAGE-5 ALLOCATION BLOCKER IS CLOSED: every tag the bundle machines block
constrains on now exists and is applied.

Gauntlet ALL GREEN (87) on vcloud; repo-lint 0 fail.
