dc1-region workstream START: .6 region VM bootstrapped to Ready + MAAS 3.7 procedure researched
...
Operator ruled dc1 node-handling "Rebuild fresh into dc1-region". Measured:
dc1's full set is in the Office1 region (9 nodes+juju Ready; .6/.7 Failed
commissioning on unset-power). Bootstrapped the .6 region VM (Office1-side,
like dc0 hot-kid): power set, renamed normal-piglet->vr1-dc1-maas-01
(convention), recommissioned -> Ready (a transient virsh-login error
cleared on retry).
Researched + recorded the MAAS 3.7 region+rack install/init (changelog
Item 7; matches Office1 3.7.2 + PostgreSQL 16; external DB required;
createadmin=SEC-020 operator one-shot). Remaining next-session: extend
aux-carve for -maas-01 + carve .6 (10.12.68.6 + 10.12.64.6) before deploy
(hot-kid under-carve lesson); deploy jammy; MAAS init one-shot; register
region + config via tested tools; rebuild 9 nodes+juju+.7 fresh into it.
CURRENT-STATE dc1 block + ledger NEXT updated. repo-lint 0 fail.

dc0 MAAS hostname convention: rename tailscale + juju controller (operator correction)
...
Operator: "You are not following naming conventions." Renamed the two
random-named vr1-dc0-region machines to convention (hostname == libvirt
domain == power_id, lib-hosts:26): known-marten->vr1-dc0-tailscale-01,
subtle-grouse->vr1-dc0-juju-01. All 11 dc0-region machines now vr1-dc0-*.
Cosmetic to tooling (carve/power resolve by boot MAC); load-bearing for
operability. changelog Item 6 + CURRENT-STATE note.

dc0 tailscale .7: carve applied+verified + deployed jammy (carved-and-ready)
...
LIVE (gated): carved the .7 router's two legs (metal-admin 10.12.8.7 +
provider-public 10.12.4.7 VLAN 5002, no br-ex) via the new aux-carve;
check pass=8/0. MAAS-deployed jammy -> Deployed, sshd live on 10.12.8.7.
State: dc0 .7 = carved-and-ready. Two JOIN prerequisites remain, both
off-session: (a) tagged pre-auth key + Headscale autoApprovers/ACL
(operator key is PLAIN; join NOT attempted); (b) SSH access via
vr1-office1-svc (region injects only that key; operator holds it).
CURRENT-STATE tailscale block + changelog Items 3-5 updated; dc1 ruling
recorded (build vr1-dc1-region first, no migration).

dc0 tailscale .7: MAAS power+commission (Ready) + aux-carve tooling
...
Provision the dc0 Tailscale .7 subnet-router toward phase-03 Step 3.3
(Horizon over the tailnet). LIVE (gated): set power_type=virsh on the
already-enlisted known-marten (n4parh) via the DC-region-reachable
10.12.8.2 address, commissioned -> Ready.
Tooling (hard rule 4 -- no artifact carved this 2-leg shape):
- lib-hosts.sh CARVE_AUX_HOSTS isolates the .7 VM from every HOSTS
consumer; inert octet(7)/boot-MAC entries; NODE_CARVE_TAILSCALE_PLANES.
- dc-node-carve.sh is_tailscale_host/is_two_plane_host -> metal-admin +
provider-public RAW, no OVS br-ex (juju-controller idiom, octet 7),
keyed on stable lib-hosts name + boot MAC; --host accepts aux, bare
apply still HOSTS-only.
- harness t01/emit_tailscale + T28..T33 (pass + tsbrex/tscarved failing
directions). 58/0; repo-lint 0 fail; gauntlet ALL GREEN (101).
Implements D-129(iii) amdt (2026-08-07) + D-134 octet map; no new D-num.
Operator rulings: dc1 "No migration. Build region on DC1 correctly.";
join key is plain (not tag-scoped) -> tailscale JOIN stays blocked on a
tagged key + Headscale autoApprovers/ACL (N1). Provisioning to
carved-and-ready is unblocked.
