vr1-dc1 bundle render (9-node role-separated) + expansion review record ...

Render (committee Fork-2 hand-render), validated by the extended checker:
- bundle.yaml: machines "8"-"11" (tags=openstack) -> "0"-"8" role+DC tags (block
  style); every `to:` re-homed (quorum trio -> control 0/1/2; nova-compute 3->2 on
  compute 3/4; ceph-osd -> storage 5-8; scaled apps + utilities -> control);
  ovn-chassis -> the 2 dc1 compute provider MACs (52:54:01:d1:04:02/05:02).
- overlays/vr1-dc1-machines.yaml (NEW): per-DC retag (machines-overlay merge is
  VERIFY-LIVE at `juju deploy --dry-run`).
- overlays/dc-ha-scaleup.yaml: tokens rendered to logical control ids 0/1/2
  (DC-neutral); header updated; stale ceph-osd-3 comment -> 4.
- provider-bundle-check.py: ovn-chassis MAC check skips the VR0 Pattern-A set on a
  role-separated bundle (the validator CAUGHT a real YAML flow-comma render bug).

Validated: base + FULL dc1 deploy input (3 overlays, --dc vr1-dc1) PASS; harness
15/15; gauntlet ALL GREEN (78); repo-lint 0-fail.

Expansion review (3 read-only reviewers) recorded in
docs/audit/stage5-expansion-review-20260724.md: relations/bindings/subordinates
HOLD under role-sep (uniform 6-NIC, SEC-011); no channel/pin change; open
resolve-before-deploy items (vault VIP, v4-vs-dual-stack phasing) + deploy-gate
script gaps + VERIFY-LIVE gates. NetBox->deploy coupling routed to Chat as a new
PROPOSED D-number (Fork-2 escalation). No cloud state mutated.

provider-bundle-check: overlay merge + per-DC VIP bands + placement invariants ...

The committee's non-negotiable placement "spine" so the vr1-dc1 render is
machine-checked, not eyeballed. The checker was placement-blind (D-052 bindings
+ mysql=3 only), so any render could silently ship decorative HA.

- --overlay FILE: juju-like merge -> validates the EFFECTIVE deploy input
- --dc vr1-dc0|vr1-dc1: per-DC VIP bands (default dc0 = base; un-param run
  byte-identical to before). Closes the dc1-VIP-outside-the-check gap.
- placement invariants (fire only on a role-separated machines block, self-skip
  on the base bundle): no dangling to:; LXD->control, ceph-osd->storage,
  nova-compute->compute; num_units>=2 spread across that many DISTINCT machines
  (anti-affinity); ceph-osd==storage count, nova-compute==compute count.

Harness 15/15 (7 new behavioral cases); gauntlet ALL GREEN (78); repo-lint 0 fail.
Machines-block overlay merge is confirmed at `juju deploy --dry-run` (VERIFY-LIVE).

Patches

D-060: revert to Pattern A; supersede D-057/D-058 ...

Revert provider NIC to Pattern A (MAAS-built OVS br-ex) on the existing D-052/D-053 scheme. bundle.yaml clean bf7de5a checkout (provider-public x11, VIP triple .4/.8/.12, all 4 br-ex MACs); lib-net.sh + carve back to D-052/D-053; NEW provider-bundle-check.py gate; standup retargeted; teardown.sh + teardown runbook updated. Retire: phase-00-maas-recidr.sh, provider-vip-standup.sh, d057-bundle-check.py, and the 3 provider-vip/reconfigure runbooks.
