Pin juju-01 MACs, add both controllers to lib-hosts at the ruled .5 ...

Twelve measured MACs (six per DC, virsh domiflist) pinned into both
substrate roots; <dc>-juju-01 added to lib-hosts.sh with HOST_OCTET=5 per
the D-134 amendment and its measured boot MAC. Done now because both VMs are
ENLISTED -- the boundary modules/node-vm warns about, past which an in-place
apply can regenerate unpinned MACs and strand the node, as happened to the
nine role nodes on 2026-07-21.

No race with the running agents: they operate on the voffice1 clone; this
edit is on vcloud's, and nothing reaches their tree until someone pulls
there.

Recorded rather than smoothed over: dc1's juju-01 MACs are libvirt-generated
52:54:00: values, not dc1's schematic 52:54:01:d1: scheme -- a direct
consequence of the deliberate macs = [] at first apply.

Three exact-count assertions re-pointed to the new invariant and kept EXACT
rather than relaxed: dc-selector fleet 9 -> 10 (label corrected, since Option
C is a 9-node ruling and the 10th is D-104's), node-vm T8 9 -> 10 and T9
54 -> 60.

A real harness defect surfaced doing it: T8's grep -c 'macs = [' counts
COMMENTS, and my own comment explaining the deliberate macs = [] inflated the
count to 11 -- which reads exactly like a spurious extra node. Fixed to strip
comment lines. Same class as the ledger-scan next-free defect where a doc
merely quoting a token inflated the counter.

maas-role-tags.sh taught the utility band: adding juju-01 to HOSTS made it
refuse, because .5 is in no ROLE band -- correct behaviour meeting a new
fact. Per the amendment a utility-band host with no role token is now SKIPPED
and REPORTED, while the refusal keeps its teeth for genuine disagreement.
New cases T10 and T11; harness 9 -> 11.

Gauntlet ALL GREEN (87) on vcloud; opentofu-validate PASS; repo-lint 0 fail.

Chain-audit deploy path: DC-aware preflight, dc1's real overlay set, Fork-3 role tags ...

Findings 16-20 from the D-136 chain audit, actioned.

preflight P2 is DC-AWARE and validates the deploy's ACTUAL overlay set. It
hardcoded --dc vr1-dc0 with no dc1 branch while dc-dc-phase4 invokes it BARE
as the dc1 gate and tells the operator to expect PASS -- so a dc1 operator
got a green gate that validated dc0's numbers against dc0's bands and never
parsed a dc1 artifact. It also passed one overlay where the deploy passes
two. DC=vr1-dc1 now merges vips + machines for that site.

dc1's deploy command names ALL its overlays. phase-4 Step 4 named only the
vips overlay, so a dc1 deploy run as written merged a machines block still
saying tags=openstack-vr1-dc0 -- grep for vr1-dc1-machines across runbooks
and scripts returned ZERO, i.e. that overlay was in no executable path. The
step now carries the full command, states dc-ha-scaleup is deliberately
excluded per R6, and adds the --dry-run machines-merge confirmation the
overlay's own VERIFY-LIVE note required and no step performed.

phase-6 deployed with NO VIP overlay and named a file that never existed.
Both blocks -- including the real apply against a live model -- passed
overlays/${DC}-hostnames.yaml, never authored, and no VIP overlay;
post-ruling-3 that is a merged input with zero VIPs including the designate
those commands exist to add.

scripts/maas-role-tags.sh ships Fork 3 (harness 9/9). Every machine
constrains on two tags; only the site tag is ever created, so the three role
tags exist nowhere and juju's allocation constraint matches no machine.
Role is DERIVED from two signals that must agree -- the ruled D-134 octet
band and the host's own name token -- and disagreement REFUSES rather than
picking one. Nodes match by pinned boot MAC, never hostname. Dry by default,
every write read back, absent CLI distinguished from unreachable service.
apply --commit is a live MAAS mutation and is NOT run here.

OWNED, third appearance of the IFS trap: ROLES="control compute storage"
under IFS=$'\n\t' does not word-split, so the script reported one absurd tag
named 'control compute storage'. Caught by its own harness pre-ship. Same
class as commit 1's CHECK 1 death and phase-05's aborting captures -- these
strict-bash gates should use arrays, never space-separated string lists.
Also fixed: the role-derivation refusal swallowed its own diagnostic.

Gauntlet ALL GREEN (87) on vcloud; repo-lint 0 fail / 614 files; preflight
verdict unchanged in kind.
