Stage 5 dc0: vault init DONE + ovn-central RESOLVED; D-142 vault-init QoL saved ...

Live (operator-run one-shot, recorded no-secrets): phase-02-vault-bringup Steps
2.1-2.3 on the dc0 rack (-m vr1-dc0), vault active/idle, root CA generated
(valid 2026-08-05 -> 2036-08-02). ovn-central/3,4,5 ALL active -- OVN NB/SB
cluster formed; the multi-session cert saga is closed by the two fixes landed
this cycle (dc-node-etchosts Step 1.2b CN delivery + D-052 '' -> metal-admin).

Engineering saved (PROPOSED, not executed -- operator: run current commands now,
test QoL next opportunity):
- D-142 PROPOSED: vault-init workflow QoL sweep (APPROVED-IN-PRINCIPLE, IMPL
  DEFERRED; R2 off-host transport UNRESOLVED). Distinct from D-068 (substrate) /
  D-011.6 (manual-unseal bar).
- docs/audit/vault-init-qol-proposal-20260805.md: R1-R5 + full hidden-prompt
  safety analysis + tee-write residual + pre-init writability probe + R3 harness
  constraints + operator's verbatim safety constraint.
- runbook-fold-register F13: -m openstack -> -m vr1-dc0 / run-location = DC rack
  (D-138) on phase-02-vault-bringup (scope stretch stated).

CURRENT-STATE + as-exec updated (L10 coupling). Security hygiene: child token in
operator paste was ttl=10m/expired -> benign, not stored. Remaining (separate):
ceph-mon/2 + ceph-radosgw/0 allocating (apt-wedge) cascade.
