Capacity gate re-measured PASS (RAM 870/1024 = 85%, FIT, 154 GiB headroom).
Plan asserted on content -- exactly two resources, both the new VM. Applied
2 added / 0 changed / 0 destroyed; MACs measured and pinned; converged ZERO
DIFF with live virsh domiflist byte-identical to the pin; virsh power set.
Enlisted as hot-kid / tw7ptw.

Corrected against measurement: the "1 add" figure in both new comments and in
D-104's amendment prose is wrong at resource level -- node-vm creates a
domain AND a volume, so it is 2 to add. The half that mattered, 0 change /
0 destroy, held.

Ordering trap measured and recorded as a standing rule: the first apply sets
running=true, so the VM PXE-enlists and auto-commissions within ~90s, and
pinning MACs is an in-place libvirt_domain update that BOUNCES the guest --
stalling that commission at "Loading ephemeral". After pinning MACs on a
freshly-applied VM, assume commissioning was interrupted and re-commission
deliberately. Recovery is abort -> New -> commission.

dc1's region VM is authored but NOT applied.
