INCIDENT RESOLVED + G10 depth-4 boot gate PASS: all 9 DC0 nodes enlisted in MAAS ...

Region restart recovered Temporal; dhcpd verified by PROCESS on both
controllers (0->1 each), not by service_set. One restart fixed both sites,
confirming the single wedged-Temporal root cause. The identical canary that
had failed then enlisted immediately -- proof it was the real blocker.
All 9 nodes enlisted with shapes exactly matching D-121 Option C
(3x16/64, 2x12/48, 4x8/24): node VMs inside vvr1-dc0 PXE-booted from the
Office1 region across the transit and run the ephemeral kernel = real
nested KVM at depth 4, proven behaviorally. Appendix-A entry queued for
this new incident class.
CURRENT-STATE updated in this commit (GA-R1/C1).
