Ruling 3 commit 2: dual-stack ADD -- R2 and R11 are now BUILT, L3-9 resolved ...

Both per-DC VIP overlays re-rendered dual-family: every app carries
prefer-ipv6: true and a six-address vip, and vault .61 + designate .62 are
built. Measured both DCs: 13 clustered VIPs (13 dual-family) + 12 hacluster
principals all carrying a VIP -> PASS. With dc-ha-scaleup stacked: 13
principals, PASS -- R6's ruled ordering (VIPs before the HA overlay) is now
satisfied and executable. Two ruled-but-never-built decisions became
artifacts in one pass.

L3-9 RESOLVED. dc-dc-ipv6-family-matrix.yaml is narrowed to ceph-mon only;
its ten duplicate vip + prefer-ipv6 pairs (every value an unrendered token)
are gone, removed TOGETHER -- removing the vips alone would have recreated
the defect deliberately. Both merge orders now PASS, i.e. order-independent,
which is the actual fix. ceph-mon's ULA-only networks survive because they
exist in no other file. The two Launchpad citations arguing octavia lb-mgmt
IPv6 was an open risk are removed: both were read in full and both failed,
and R8 closed that question on 2026-07-27.

Also corrected at source: CURRENT-STATE described L3-9 as "the dangerous
merge order is the one that PASSES". Measured -- that stopped being true
when invariant 9 shipped on 2026-07-28. The merge semantics it describes
remain accurate; only the green-over-loss conclusion is retired.

Gate repairs the agents caught BEFORE the edit:
- phase-01's deploy guard would have ABORTED THE DEPLOY AGAIN -- its HI regex
  (5[0-9]|60) excludes .61/.62, so it would have read 13/11/0 against a
  required 11/11/0. Widened, counts moved to 13, verified 13/13/0 -> DEPLOY.
  Second near-miss on this one guard across two commits.
- pre-flight-checks CHECK 1 hardcoded if(n!=3) and would have failed all 13.
  Now takes a triple OR a sextet and asserts a sextet's last three legs are
  really v6. Proven able to fail on both new paths.

Harnesses re-pointed, never deleted. T16/T17 asserted R11's gaps were OPEN;
inverted to the surviving invariant and PAIRED with new T16b/T17b that remove
a VIP and demand the check still fires. T20/T21 had become no-ops that would
have gone GREEN testing nothing -- inverted. A v4-only twin fixture keeps the
pre-dual-stack cases testing their own invariants. The renderer harness now
proves reproduction on both shapes, including new T3b against the live
dual-family overlay.

provider-bundle-check 33/33; render-dc-overlays 18/18; render-baseline 10/10;
preflight 16/16; gauntlet ALL GREEN (85) on vcloud; repo-lint 0 fail / 611.

PREFLIGHT: BOTH STANDING REDS CLEARED, 3 fatal -> 2 fatal. The remaining two
are the deliberately-absent octavia-pki overlay and MAAS unreachable from
vcloud, which R10 measured clears on voffice1.

FLAGGED, not hidden: octavia's dual-family API VIP is an inference from R2
applied evenly, not a quoted ruling. Worth one operator confirmation.

Ruling 3 commit 1: bundle.yaml is VIP-free; dc0's VIPs are now a RENDERED overlay ...

The 11 inline vip: lines are gone from bundle.yaml and live in
overlays/vr1-dc0-vips.yaml, GENERATED by scripts/render-dc-overlays.py from
render/values/vr1-dc0-vips.yaml -- the renderer's first real output.
placement's then-empty options: block was dropped rather than left parsing
as null. Ruling 3's dual-stack ADD is commit 2 and is NOT in here.

PROVEN NEUTRAL by the ruling's own named check: provider-bundle-check on the
pre-extraction bundle and on the merged pair produce line-for-line identical
output, same known designate failure included. A structural diff separately
confirmed only vip moved -- applications 56 -> 56, relations 108 -> 108,
every other key byte-identical.

The 11 inline comments were carried, not dropped: extracted verbatim by
parser rather than retyped, via new optional per-app comment support in the
renderer. An app with no comment emits none, so dc1 still reproduces
byte-for-byte at 1634 bytes. The B1/B5 tokens stay DEFINED in bundle.yaml's
header and the overlay header names that, so the references do not dangle.

The blast-radius repair is the bulk of this, and every item was found BEFORE
the edit by the read-only agent sweep:

- preflight.sh P2 validated the bare base (11 phantom failures post-move) ->
  merged input.
- pre-flight-checks.sh CHECK 1 read the base as raw text and would have seen
  ZERO VIPs. This is BLOCKER-1, fixed the ruled way and not by bumping the
  count. Measured trap: the file sets IFS=$'\n\t', so a space-joined string
  reached grep as ONE filename, grep exited 2, pipefail propagated and the
  gate died silently mid-check. Fixed with a bash array.
- phase-01's RUN block gates juju deploy on 11/11/0 and would have read
  0/0/0 and ABORTED THE DEPLOY. Both guards now span base + overlay, and a
  second latent bug was fixed in the same edit: grep -c over two files prints
  one count PER FILE, so the bare $( ) captured a two-line string and every
  numeric test would have failed anyway. Now awk-summed; verified 11/11/0.
- phase-01's Octavia SAN derivation raised KeyError, swallowed by || true
  into an empty VIP. Now reads the overlay, deriving 10.12.4.57.
- phase-00 teardown, dc-dc-phase4's "NO VIP edits" guidance, appendix-A L3,
  and render-baseline's now-unverifiable bundle hash all repaired.

Harness 30 -> 31. The fixture base is now bundle + dc0 overlay, since that
pair is the deploy input; T16 renamed to match. NEW T31 asserts the bare base
fails for every clustered principal, so "deployed without its overlay" is a
tested state rather than an assumption.

Gauntlet ALL GREEN (85) on vcloud; repo-lint 0 fail / 610 files scanned.
Still red and expected: CHECK 1 at OK=11 want 13, and designate -- R11's
.61/.62 remain ruled-but-not-built, which is commit 2's job.
