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.

Exercise the dc1 arm of the apex lookup; confirm P2's rc=2 classification ...

T19-T23 all ran at the default --dc vr1-dc0, so the dc1 v6 bands
(f03:11::/64, :320::/64, :321::/64) were resolved by no case at all. The
renderer's first real output is per-DC overlays, and a gate observed in
only one DC mode is the same only-ever-seen-one-way untrustworthiness
T16/T18 exist to rule out.

T29 resolves the dc1 bands and passes. T30 proves a dc0 v6 leg under
--dc vr1-dc1 FAILS, so a cross-DC copy-paste of a rendered overlay
cannot pass -- the v6 analogue of T15.

Also verified rather than assumed: the checker's NEW exit-2 refusal
(dual-family vip + unreadable apex) is classified correctly by preflight.
P2 rc=2 is already ruled could-not-evaluate -> FAIL (preflight.sh:36,81)
and harness case T14 locks it, so a refusal can never downgrade to a
warning. No change needed there.

Harness 28 -> 30. Gauntlet ALL GREEN (84) on vcloud; repo-lint 0 fail /
605 files scanned.

VIP arity gap CLOSED + R11's three ruled gate changes executed ...

provider-bundle-check.py could not express what R2 and R11 already ruled:
:137 required exactly 3 addresses per vip (a dual-family VIP is 6, so it
would have failed EVERY application) and :149's octet extraction returned
the whole string on a v6 literal, leaving every v6 leg trivially unique
and unchecked. The apex now holds the dual-family set a renderer will
emit, so the only gate that validates overlays could not validate what is
about to be produced.

Arity: a vip is now a v4 triple OR a dual-family sextet. The v6 legs are
validated against the per-DC v6 /64s READ FROM THE APEX RECORD (D-136
option (D)), reusing dc-plane-ipam.sh's (role, kind) keying -- the
provider leg takes the dedicated GUA VIP /64, admin/internal their plane
/64s. The v6 host part must MIRROR the v4 octet textually. prefer-ipv6
and the v6 legs are COUPLED in both directions: the measured L3-9 finding
is that the merge order which keeps prefer-ipv6 while dropping the v6
legs is the one that exits 0. An unreadable apex REFUSES at exit 2; a
v4-only bundle needs no apex.

R11 (D-020 amendment, ruled 2026-07-27), same pass: band 50-60 -> 50-99
in both separately-named sites; VIP_COUNT_EXPECT 11 -> 13;
EXPECT_PUBLIC_VIP deliberately stays 11 (measured -- neither vault nor
designate has a public binding); and an hacluster principal with no vip
now FAILS, since cluster_count is asserted nowhere and a 3->1 rewrite of
all 20 values produces a byte-identical PASS.

Measured consequence, not glossed: two sub-checks flip PASS -> FAIL
(designate's missing VIP; CHECK 1 at OK=11 want 13). preflight was
ALREADY exit 1 before this change and is still exit 1 after -- no deploy
path that was open is closed. Both reds are the ruled gate reporting real
work owed; per R6 the .61/.62 VIPs land before the HA overlay.

Harness 15 -> 28. Three cases RE-POINTED rather than deleted: the fixture
base splits into a pristine repo bundle and one carrying designate's
ruled .62, with new case T16 asserting the pristine bundle DOES trip the
new invariant. When .62 lands, T16 gets re-pointed, not deleted. Proven
able to both fail and pass on the same check (T16 red / T18 green).

Gauntlet ALL GREEN (84) on vcloud; repo-lint 0 fail / 604 files scanned.

Scope was operator-gated: "Fix the arity gap first, then start the
renderer", with the arity-alone vs arity-plus-R11 fork put separately and
answered "Arity gap + R11's three ruled changes (Recommended)". OPS under
GA-R3, no D-number.

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).
