 - vvr1-dc0 RUNNING (108 vCPU / 416 GiB / autostart off); guests untouched; convergence = no diff.
 - Next: step B (bootstrap vvr1-dc0: site-headend-install --role rack --host-nodes + SEC-010 check,
   OPNsense base prep ON the VM) -- needs transit reachability + the dc0 key (D-126 DC rows).
+- PAUSED at the A/B boundary (2026-07-19): operator moving to a fresh session. Step B's measured
+  starting facts: vvr1-dc0 NICs = mesh-vr1-dc0-office1 + vr1-dc0-uplink (NO transit NIC yet --
+  measure how reach works before wiring ssh; D-124 tfvars local+present; dc0 key minted).
+  Fresh session: CURRENT-STATE first, then resume at runbook step B in the dc0-deploy logged window
+  (same-day log appends).
