Author both Stage-5 blockers (NOT applied); Octavia merge question resolved
...
Octavia RESOLVED as a clean negative. The chain audit flagged that
octavia-pki.yaml lands last and writes the same applications.octavia.options
map as the vips overlay, so under replace semantics octavia would lose its
vip and prefer-ipv6 with every offline gate still green. Researched against
source: juju 3.6 pins charm v12.1.1, and mergeStructs does
dstMap.SetMapIndex(srcKey, srcMapVal) per key for map-kind fields.
ApplicationSpec.Options is a Go map, so it deep-merges -- both overlays' keys
survive. The merge path is byte-identical between 2.9 and 3.6. The checker's
"MIRRORS juju's documented merge" comment is now sourced rather than assumed.
Logged: LP #2002371 (Triaged/High, unfixed) -- an EMPTY/null options: key
WIPES the base map rather than merging. Our overlays lack that shape and
nothing gates against acquiring it.
R1 AUTHORED. modules/node-vm gains osd_disk_size_bytes, default 0 = creates
nothing; the volume is count-gated and the disk entry appended via concat, so
an opted-out node has no extra resource and no plan diff -- precondition 4
verbatim. Four storage nodes per DC set osd_gib = 500: 8 volumes, not 18.
500 GiB is D-121's own budgeted figure (4x500Gi/DC = PASS, 5.31 TiB margin),
and D-121 records that footprint as an assumption pending an OSD-sizing
decision, so it is evidenced but not separately ruled. Headroom caveat
surfaced: dc0 has 2.0T available against 2.0 TiB nominal -- thin-provisioned,
so creation is cheap, but there is no room for those OSDs to fill.
D-104 AUTHORED. A 10th keyed entry per root, <dc>-juju-01, planning 1 add /
0 change / 0 destroy. The nine role nodes are untouched. 8 GiB / 4 vCPU are
the values the capacity gate actually modelled; disk 100 GiB is the authoring
value the amendment left open. MACs deliberately empty -- correct only before
enlistment, and they must be pinned from measurement after the first apply or
this reproduces the 2026-07-21 MAC-regeneration trap.
NEITHER IS APPLIED. opentofu-validate PASS on both roots; no apply run. Both
are live substrate mutations and individually operator-gated.
R1 precondition 3 is NOT satisfied and I am not treating it as such: the
amendment requires verifying BEFORE the apply that re-commissioning preserves
the D-134 statics and pinned MACs, and that needs live MAAS, absent here.

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.

D-136 step 6: the chain audit -- R9's drift gate built, three refusals, two dead cases
...
Three read-only lenses over data source -> renderer -> deployment mechanism,
the ruled final step of D-136 option (D). Lens 3 was adversarial and made
the chain produce wrong-but-green THREE times, all executed.
All three converged on one root cause: dc1's overlay was byte-gated and
dc0's was gated by nothing. render/values/ was referenced by zero scripts
and zero harnesses, while preflight P2 feeds the deploy gate dc0's overlay.
R9's render-drift check had been RULED and never built.
Executed wrong-but-green:
- transposing two apps' octets in the dc0 overlay (consistent, in-band,
correct prefixes) -> PASS
- changing ONE WORD, family: dual -> v4, silently reverting dc0 to IPv4-only
against R2's ruling -> PASS, because dropping prefer-ipv6 and the v6 legs
together satisfies invariant 9, and vip_dual is printed but never asserted
tests/render-drift/ is R9's gate, built. It iterates render/values/*.yaml,
reads each file's own output: field (inert until now), renders and
byte-compares. A new per-DC values file is gated the moment it is committed.
Non-zero floor plus a proof-of-teeth case that mutates a copy and requires
red.
Three refusals where the chain took the last writer silently:
- duplicate (role, kind) in the apex, in BOTH readers. Appending one spare
prefix -- routine IPAM work -- re-homed every dc0 VIP into a different /64
and went green, because the gate checks overlay-vs-apex agreement and both
sides read the same wrong value. The winner depended on JSON array order.
- duplicate app name / duplicate octet / out-of-band octet in APP_OCTET. A
duplicate name emitted two YAML blocks, safe_load kept the last, and one
app's ruled octet vanished with nothing red.
Two harness cases that could not fail:
- T3b's byte-compare was CIRCULAR -- header derived --from-overlay $LIVE
then compared --against $LIVE, so a third of the bytes were self-copied.
Proven by rewriting a header line to a false claim and still matching.
- T29's own fixture was inert; its assertion held from the overlay alone.
OWNED: my first T29 re-point asserted a --show-legs flag THAT DOES NOT
EXIST. I invented an interface instead of reading one. The harness caught it
immediately; replaced with real behaviour and recorded rather than quietly
fixed.

D-109 ruling note: the Octavia controller cert gains IPv6 IP SANs
...
Operator ruling (GA-R5), exact utterance: "Yes, add the v6 IP sans."
Recorded as a D-109 RULING NOTE (2026-07-29); OPS under GA-R3 -- a
generator change extending an already-ruled principle to a surface D-109
governs -- so no new D-number and next-free stays 138.
The generator now emits IP.1 = this DC's provider v4 leg and IP.2 = its
provider v6 leg, both derived from the same per-DC overlay under R7's $DC
selector. Verified: dc0 -> 10.12.4.57 + 2602:f3e2:f02:11::57; dc1 ->
10.12.64.57 + 2602:f3e2:f03:11::57; and a v4-only control emits NO v6 SAN,
so the generator stays correct on a tree where the dual-stack ADD has not
landed. Admin and internal legs stay EXCLUDED exactly as before --
DOCFIX-067's design has always been provider-leg-only.
Two repo guards fired and both were right: repo-lint L5 rejected a heading
that LED with the D-number (it reads as a second definition -- the third
time this trap has bitten on this branch), and L10 rejected the change for
touching a design-decisions Status line without CURRENT-STATE in the same
commit.
Observation logged, not acted on: amphorae reach the controller on o-hm0's
charm-generated fc00::/64 ULA, not on any VIP leg, so neither SAN matches
that path. Measured upstream, the controller verifies the amphora by UUID;
the reverse direction was not established from source. Settle by inspection
at the Octavia step rather than assuming.

Octavia: R8a BUILT (record was false), two stale surfaces, R7 generator de-frozen
...
Follows an upstream/vendor research pass answering "can Octavia run full
IPv6" -- yes; nothing inside Octavia requires IPv4. charm-octavia creates
the lb-mgmt subnet with ip_version: 6 and has no IPv4 code path at all; the
health manager is v6-capable both directions; the amphora agent binds '::'
and verifies certs by amphora UUID, not IP; and Nova metadata is not a
dependency (config_drive=True). Surviving v4 pressure is soft or external.
R8a BUILT. phase-05-octavia-verify.sh now compares o-hm0's MTU against
lb-mgmt-net's (resolved BY TAG, never by name), fails in either direction,
and REFUSES when a value cannot be read. This closes the LP#2018998
obligation, live on our exact pin after its 2025-12-31 recurrence.
THE DECISION RECORD HAD CLAIMED THIS SHIPPED. design-decisions.md carried a
present-tense "Delivery: the assertion ships in ..." written on the day of
the ruling, while the file held zero MTU references and its last commit
predated the ruling by a month. Corrected in place. Sharper than the usual
ruled-but-not-built class: the decision doc was the false witness.
TWO OWNED ERRORS:
- I concluded "no octavia harness exists" from a NAME grep. The script's
harness has always been tests/phase-05. Duplicate deleted, R8a cases
folded into the real one.
- My first MTU draft ABORTED the script: a $( ) under set -euo pipefail with
inherit_errexit exits the run rather than reaching the refusal branch. The
pre-existing harness I had just declared nonexistent caught it. Same class
as commit 1's IFS word-splitting trap; both now locked by cases.
Two live surfaces still contradicted R8 -- dc-dc-phase4 and the workflow doc
both called lb-mgmt IPv6 "a real, open risk" and recommended keeping it
v4-only, citing the two refuted bugs. A reader would have re-litigated a
closed ruling in the wrong direction. Both superseded in place.
R7 executed: phase-01 Step 1.0-GEN gains a $DC selector; the baked
/CN=VR0 DC0 CA subjects derive from it, and the VIP gate derives this DC's
provider prefix from the same overlay it read the VIP from -- R7's explicit
"read the MERGED input" caveat. dc1's 10.12.64.57 used to hard-ABORT, so no
dc1 artifact could be produced. Verified both DCs, negative control still
aborts.
Logged not built: the controller cert's CN/DNS SANs still carry dc0.vr0
(outside R7's ruled scope, inert while os-public-hostname is unset), and it
gains no IPv6 IP SAN though the VIP is dual-family -- a gap, not a break,
and adding v6 SANs needs its own ruling.
tests/phase-05 14 cases (was 9); gauntlet ALL GREEN (85) on vcloud;

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.

GA-R4 ledger rotation (fifth pass) + the 2026-07-29 bounded close bookend
...
Operator: "Process the rotation now".
The live ledger was 296 lines against the 300-line cap and this session's
bookend would have taken it to 321. Rotated OLDEST-FIRST per GA-R4 rule 3:
the two oldest live summaries -- 2026-07-26 (D-137 build + committee audit +
remediation) and 2026-07-27 (creds consolidation + the STAGE 4 CLOSE-OUT) --
moved VERBATIM to docs/archive/session-ledger-rotated-20260729.md. Verified
by diff against HEAD that they were MOVED, not rewritten. Each still points
at its own archived full body, and no live surface referenced them by their
old location. Live ledger now 264 lines.
The bookend is 15 content lines against GA-R4 rule 1's 15-line cap --
measured, and trimmed from a 21-line first draft rather than left over
(the fc00d54 precedent). It records the arity gap + R11's three ruled gate
changes, the renderer and its byte-for-byte reproduction, the measurement
that INVERTED the ordering, ruling 3 commit 1 with the deploy-gate near-miss,
and what commit 2 owes.
The machine-derived block is a CONFIRMATION, not a re-seed: ledger-scan was
re-run today and every value is unchanged (3 open decisions, SEC 21, next-free
D 138 / DOCFIX 205 / BUNDLEFIX 053), so the block is annotated with the
re-verification date rather than rewritten.

Values-file provenance symmetry; repair the mangled ledger rotation note
...
Two small corrections found on review.
(a) The values file recorded `apex_record` only on the dual-family path, so
the dc0 v4 file carried no provenance at all -- and the asymmetry would have
read as a bug once commit 2 gives dc1 the apex field. Added `source_v4`,
recorded on BOTH families, because the v4 prefixes come from lib-net.sh and
NEVER from the apex: a values file carrying only `apex_record` misattributes
half its own inputs. Re-derived dc0; the rendered overlay is byte-identical
(a3b30e40...) and dc1 still reproduces exactly.
(b) docs/session-ledger.md's third rotation note was left MANGLED by an
earlier edit -- a sentence broke off mid-number and ran into a stray fragment
of the 2026-07-25 MAAS-admin-recovery summary. Flagged at this session's open;
repaired here rather than only reported, with a note saying so and a pointer
to that summary's archived body.

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.

Render-pipeline step 4: the renderer, reproducing a reviewed artifact byte-for-byte
...
scripts/render-dc-overlays.py. Two stages, split exactly where forward item
F2 froze the interface: `derive` (apex + lib-net.sh -> a per-DC values file)
and `render` (values -> overlay text). `render` is PURE -- no apex, no
network, no clock -- so it is offline-testable and a future CI job re-runs
only `derive`.
ORDER INVERTED BY MEASUREMENT. The plan was ruling-3's VIP extraction first.
Three read-only agents measured two facts that reversed it: the byte-for-byte
reproduction window is still open (the live dc1 overlay is still identical to
the frozen fixture) and closes on its own when the R2/R11 reconciliation
lands; and the extraction's blast radius is far larger than ruling 3's "2
commits" -- it breaks the phase-01 deploy gate (juju deploy runs only on
11/11/0), the Octavia SAN derivation, preflight in two places, and 8 of 30
harness cases. Better done BY the renderer, so dc0's overlay is a validated
output rather than a hand edit.
A TEXT emitter, not yaml.dump: a round-tripper destroys the comment header,
normalises the quoted vip scalar, and imposes its own key order -- all three
are load-bearing bytes. Two things are INPUT rather than invented: the 12-line
comment header (lifted verbatim via --from-overlay, so a reproduction run is
honest about which bytes the tool actually generates) and the ascending-octet
emission order (sorting by name reproduces nothing). The ruled app->octet map
is READ with ast out of dc-plane-apex-import.py rather than restated as a
second drifting copy.
RESULT: output hashes to 3f93ecb3..., identical to both the committed overlay
(1634 bytes) and the frozen fixture. PROVEN ABLE TO FAIL, not merely observed
passing -- three seeded faults all fail the compare (wrong octet, dropped
header, dc0 prefixes against the dc1 artifact).
THE ARITY WORK PAID FOR ITSELF WITHIN THE HOUR. The first dual-family output
was malformed: the values file stores each v6 /64 base with trailing colons
stripped, and the emitter joined with a single colon -- 2602:f3e2:f03:11:50,
not a valid address, and it still looks like one. provider-bundle-check,
fixed yesterday for exactly this class, rejected all 13 applications. Locked
by T13/T13b.
End to end: apex -> values -> renderer -> overlay -> gate. The dual-family
dc1 render with R11's ruled-but-unbuilt apps produces 13 VIPs, all
dual-family, PASSING provider-bundle-check --dc vr1-dc1 including the new
hacluster invariant. Nothing committed has been regenerated by it yet.
tests/render-baseline gains T6, the reproduction case its README invited --
ADDED, with T1-T5 deliberately not repointed at live, and comparing against
the FIXTURE because live is supposed to diverge. T6 proven able to fail by
making the renderer sort alphabetically.

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.

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.

Record the deferred skill-sweep candidate for the Stage-5 close
...
Operator direction: leave the skill sweep for the stage close. GA-R6 ties the
sweep to a STAGE close and this session closed none; batching it there also avoids
regenerating the dated Chat snapshot twice.
The candidate is recorded rather than left in the transcript -- which is the exact
failure this session's close sweep spent its time correcting. It is a COMPLEMENT
to an existing skill invariant, not a new one: "a checker that cannot fail is not
a gate" has an inverse that also bites. Three gates built this session could only
ever FAIL, because everything they assert was absent, and each needed a
constructed fixture case to prove it could go GREEN. dc-node-v6-carve then
demonstrated it live, flipping dc0 to PASS while dc1 still read FAIL.

Close sweep: correct a step-3 heading that went stale within the session
...
The final step-3 entry read 'MAAS, lib-net AND APEX HALVES COMPLETE'. True when
written, but an understatement once the node carve landed above it -- a reader
skimming headings would have concluded a half was still owed. Corrected to name
all four layers, with the node half cited, and with what is deliberately NOT part
of step 3 stated explicitly (v6 gateway/DNS, and G17's first-boot verification).
Same stale-surface class this project keeps finding, and the same lesson: caught
by a close sweep, not by a gate. Nothing reads prose.

Ledger bookend trimmed to the GA-R4 15-line cap (was 16)
...
Calibrated against precedent with the same counting method: the 2026-07-26 close
is exactly 15, so the cap is achievable rather than nominal. Also measured, and
worth noting rather than quietly matching: the STAGE-5 GROUNDING AUDIT close in
this same file runs 33 lines -- an unremarked breach of the rule this trim
respects. Flagged, not fixed here; rewriting a landed bookend is a separate call.

GA-R4 session close: bounded bookend + ledger rotation (fourth pass)
...
Close bookend for a session that merged the grounding audit to main, executed
Phase 0 and all three R15 gate fixes, took six GA-R5 rulings including D-136's
adoption at option (D), and executed step 3 of the render pipeline end to end
across both DCs.
Two GA-R4 breaches fixed in the writing: the first draft ran 26 lines against the
15-line summary cap, and appending it took the ledger to 316 against the 300-line
cap. Tightened to 15, and the oldest remaining live summary rotated VERBATIM to
docs/archive/session-ledger-rotated-20260727.md -- the fourth rotation pass. Live
ledger now 294.
Gauntlet ALL GREEN (84), repo-lint 0 fail.

Close sweep: graduate three platform traps, rescue two changelog-only questions, fix a latent import
...
A session-close sweep for content that would have been lost. Four items.
(1) THREE PLATFORM BEHAVIOURS were recorded ONLY in CURRENT-STATE, which is a
status document that gets consolidated over time -- a durable trap does not
belong there alone. Graduated to references/platform-traps.md: MAAS auto-reserves
::1-::ffff:ffff on EVERY IPv6 subnet (so an explicit v6 band write is both
impossible and unnecessary, and is invisible in `ipranges read` -- only
`subnet reserved-ip-ranges` shows it); MAAS mode=static means EXPLICITLY
CONFIGURED, so creating a subnet addresses nothing and the carve is still owed;
and NetBox's live API returns scope.name as the DISPLAY name while this repo's
dumps normalise it to the slug, so a dump-written tool matches zero objects live.
(2) TWO OPEN QUESTIONS existed only in the session changelog -- which is
session-scoped scratch, explicitly not citable as status and consolidated away at
stage close. Both would have been lost: which host is authoritative for the gates
(now sharper, since executing R15(3) made preflight-on-voffice1 permanently
unpassable against P0-2's host-blind P5), and the provider-bundle-check arity gap
(now imminent rather than theoretical -- the apex holds the dual-family set the
renderer will emit, so the gate cannot validate what is about to be produced).
Also recorded: voffice1 tracks the precondition branch and must return to main at
merge.
(3) A latent import defect in netbox/dc-plane-apex-import.py: urllib.parse was
imported inside the __main__ guard while main() uses it. It worked only because
another module had already bound the submodule -- fragile, and it would NameError
if the file were ever imported. Moved to module scope.
Gauntlet ALL GREEN (84), repo-lint 0 fail.

LIVE: node IPv6 carve both DCs -- 108 links, IPv4 untouched, 18 Ready unchanged
...
Operator-gated dc0 then dc1. 54 applied per DC, 0 errors, read-back 54/54 each.
IPv6 links 0 -> 108; IPv4 links 108 unchanged; 18 Ready unchanged. Both
dc-node-v6-carve gates PASS and dc-plane-ipam still reads 24/24 on both DCs.
The octet mirror holds across all six planes per node -- superb-piglet .121 ->
::121 everywhere, big-trout .100 -> ::100. enp2s0 correctly received nothing: the
D-100 raw provider NIC has no v4 link to mirror, and br-ex carries provider-public
instead, on the node /64 rather than the VIP /64. That falls out of deriving from
"already carries v4" rather than naming planes in a table.
The gate discriminated rather than agreeing with what it found -- it flipped dc0
to PASS while dc1 still read FAIL, before dc1 was carved.
This closes the node half of step 3, which was the correction the operator's
octet-mirror question surfaced: v6 does not arrive with the subnet, because MAAS
mode=static means an explicitly configured address.

dc-node-v6-carve harness 9/9; manifest re-recorded (84)
...
Locks the properties that matter: the octet mirror is TEXTUAL (.121 -> ::121,
never a hex conversion); the D-100 raw provider NIC is skipped for having no v4
link while br-ex is included for having one; an interface already carrying a
DIFFERENT v6 refuses rather than adding a second; a vlan with no v6 subnet is a
named error rather than a silent skip; a tag matching no machines REFUSES rather
than reporting a clean zero; and apply is dry by default.
T5 drives a fully-carved fixture to green -- every live run currently fails
because nothing is carved, and a gate only ever observed failing is as
untrustworthy as one only ever observed passing.

D-101 governing rationale recorded; node v6 carve scoped; two of my claims corrected
...
The operator's question -- "are we mirroring the assigned IPv6 octet with the last
IPv4 octet like we did before?" -- exposed two errors in what this session recorded.
(i) I said MAAS static assignment "needs only the subnet, which now exists". Wrong:
mode=static means an EXPLICITLY CONFIGURED address, which is how the Stage-4 carve
set the 90 v4 links. Measured -- all 18 Ready nodes carry ZERO IPv6 links, while
their v4 side is correctly octet-mirrored. So VIPs are mirrored (156 apex objects)
and nodes are not; 108 assignments are owed. (ii) v6 gateway_ip and dns_servers are
unset on all 12 v6 subnets, unnamed before I called step 3 complete. That
"complete" is withdrawn -- the MAAS/apex/lib-net population stands, the node layer
is the remaining half.
D-101 gains its GOVERNING RATIONALE, quoted verbatim, because it existed in no repo
surface: IPv6 unless IPv4 is NECESSARY, driven by real IPv4 sizing constraints in
future expansion -- a commercial requirement, not a preference. It records that
v4-first was DELIBERATE RISK REDUCTION so a future session does not read v4
surfaces as neglect and "correct" them; that Roosevelt has full v4 and v6 edge
transport; and that NAT64/DNS64 was considered and REJECTED on that basis -- a shim
with no Roosevelt analog, against ULA planes that are internal by design.
Node v6 carve scoped in docs/audit/node-v6-carve-scope-20260727.md: 108 assignments
mirroring each node's live v4 octet, prior art measured v4-only, blast radius
per-link and reversible, and the operator's own rationale arguing to carve BEFORE
the deploy since v6-unfriendly modules surface far more cheaply on a static
read-back than mid-bundle.

Node IPv6 acquisition RULED (MAAS static assignment); STEP 3 COMPLETE
...
Operator, exact utterance: "MAAS static assignment is correct". Recorded on the
D-134 R4 amendment. The question offered MAAS static assignment, DHCPv6, or
SLAAC/RA -- materially different, only the first already satisfied.
It CLOSES work rather than opening it: the v6 carve already applied is sufficient
for node addressing; the rack-bridge v6 legs are NOT needed and were not applied,
so dc-rack-net.sh's LEGS table stays v4-only; dhcpd6 staying off is correct rather
than a gap; and no plane needs a router advertising RAs, so the DC edges take no
new role. It mirrors how v4 node addressing already works here.
RESOLVES U17. Its "the rack bridges need v6 too" was a correct observation on the
data path, but under static assignment nothing consumes a rack v6 leg, so the
widening it proposed does not follow -- the observation held, the conclusion did
not, which is this project's standing lesson about lens findings.
Verification owed at Stage-5 first boot, since nodes are powered off: PROPOSED,
not adopted, a fourth G17 assertion that a booted node carries a global v6 address
from its plane's /64 in the ruled ::100-::200 band. Amending a gate row is the
operator's call, so G17's three assertions are unchanged here.
STEP 3 COMPLETE. MAAS, lib-net and the apex all carry the ruled values. D-134's
bands and the D-020/R11 VIP set are now artifacts rather than prose. Machines 18
Ready + 2 Deployed unchanged across every mutation. Gauntlet ALL GREEN (83).

Rack v6 legs measured: nothing consumes one yet, and the real question is how nodes acquire v6
...
Post-write safety check first: the new v6 metal-admin subnet landed on VLAN 5005,
which carries dhcp_on=True for the v4 subnet commissioning depends on. Measured
after -- rack vvr1-dc0 reports 9 services, zero degraded, dhcpd running, dhcpd6
off. Nothing disturbed; dhcpd6 off is legitimate, since MAAS starts it only for a
v6 dynamic range and none exists.
Prior art: dc-rack-net.sh already owns rack bridge legs via a site-keyed LEGS
table installed as a reboot-persistent unit, so v6 legs extend that table rather
than needing a new tool. Current table is three legs per site (rack .2, DNS
forwarder .3, edge-LAN .2), not six planes.
U17 is confirmed at the host layer -- zero global v6 on the rack, zero v6 links
known to MAAS for either rack controller. But nothing consumes a rack v6 leg
today, and the substantive question U17 did not ask is how NODES acquire v6:
MAAS static assignment (needs only the subnet, which now exists), DHCPv6 (needs a
dynamic range and dhcpd6, both absent by design), or SLAAC/RA (needs a router
advertising on the plane). Only the first is already satisfied, and they differ
materially. Presented rather than chosen; legs NOT applied.

LIVE: apex populated -- bands + 156 VIP objects, both DCs, read-back clean
...
D-136 option (D) rules the apex be populated first and the renderer generated from
it. Applied both DCs: 12 ip-ranges + 78 ip-addresses each, read-back 12/12 and
78/78, errors=0, idempotent re-run plans zero. Apex ip-ranges 3 -> 27,
ip-addresses 4 -> 160 (IPv6 0 -> 78), 156 VIP objects.
Derived rather than hardcoded except the ruled app->octet map: planes from
lib-net, v6 prefixes read from the apex itself, VIP legs computed as the three
plane bases + octet (not VIP_PREFIX_*, which lib-net unsets for dc1 per R9), and
the v6 host part as the textual octet mirror with the provider leg in the
dedicated GUA VIP /64.
vault .61 and designate .62 included though ruled-but-not-built -- reserving a
planned address is what an IPAM apex is for, and it spares a second reconciliation
when the renderer emits them.
CORRECTION TO D-136: its prose says sandbox-fidelity-check.py "gates every apex
reconciliation this coupling depends on". Measured, that script compares two JSON
dumps and touches no NetBox -- it validates the SEEDER against the upstream draft,
not apex writes. Read-back is the real verification for a write. The extension is
still owed for the sandbox loop but was not a blocker here.
A live-vs-dump shape difference bit the first version: the live API returns
scope.name as the display name ("VR1 DC0") with scope.slug as the site key, while
the repo's dumps normalise name to the slug. Built against the dump, the tool
matched zero prefixes live and REFUSED rather than silently writing nothing -- the
refusal is what surfaced it. Now matches slug-then-name.

dc1 FIP pool applied -- R4's ruled scope now complete for BOTH DCs
...
Operator: "Rule dc1 FIP pool 10.12.65.0-10.12.67.254". Validated before recording
-- inside 10.12.64.0/22, 767 addresses (identical in size to dc0's), no overlap
with the D-134 bands. Applied 1/1, read back.
Final state both DCs: check pass=24 fail=0 AND reserve planned=0 skipped=19
errors=0 -- converged and idempotent. ipranges 3 -> 29, both FIP pools reserved.
Machines 18 Ready + 2 Deployed unchanged throughout.
The ruling narrows dc1's deliberate unset list by exactly one pair; the VIP group
(R9: generated from the overlay) and the D-133-retired metal-internal stack stay
unset, now with harness guards so a future edit cannot widen it silently.
Two stale assertions RE-POINTED rather than deleted, per the standing rule against
going green by removing an assertion: dc-selector asserted dc1 unsets
FIP_POOL_START, and dc-plane-ipam T20 asserted dc1 refuses the pool. Both are
replaced with stronger checks -- the ruled value, the still-unset guards, and that
dc1 plans its OWN pool and never dc0's, which is what proves the tool reads a
per-DC value rather than a shared literal.
dc-selector 48 -> 51 checks. Gauntlet ALL GREEN (83).

LIVE: D-134's bands now EXIST -- both DCs at pass=24 fail=0, from a 6/18 baseline
...
Operator-gated, dependency-ordered: dc1 v6 carve (6 subnets), dc0 reserve (13
ranges), dc1 reserve (12 ranges). Each pre-apply re-verified in the same session;
every write read back. Subnets 18 -> 30, ipranges 3 -> 28. Machines 18 Ready + 2
Deployed unchanged throughout -- no node, no tfstate, no running service touched.
This closes the "RULED IS NOT BUILT" finding for D-134: its band table had been
prose since 2026-07-23 while MAAS held zero reserved ranges.
FINDING -- MAAS already reserves the entire low IPv6 block. Every explicit v6 band
create failed with "Requested reserved range conflicts with an existing range".
Measured via `subnet reserved-ip-ranges`: MAAS auto-reserves ::1-::ffff:ffff on
every IPv6 subnet plus :: per RFC 4291 s2.6.1, with allocatable space starting at
<prefix>:0:1::. The ruled bands sit entirely inside it, so the write is impossible
AND unnecessary. R4's "v6 bands as a second pass" is not executable in MAAS and
need not be; the tool now verifies coverage instead of writing. Execution-level
correction -- R4's intent is satisfied. Same on ULA and GUA.
Harness T19 asserted a literal string the fix removed. Re-pointed at the surviving
invariant (textual 4-99, never hex 4-63) rather than deleted, per the standing rule
against going green by removing an assertion. 25/25, gauntlet ALL GREEN (83).
dc1's FIP pool still correctly REFUSED -- unset by design, so R4 cannot close for
dc1 until ruled.

LIVE: dc0 v6 plane carve applied -- 6 MAAS subnets, each read back
...
Operator-gated ("Run carve-v6 vr1-dc0 --commit"). dc0 only; dc1 not authorised
and not touched.
Pre-apply re-verified in the same session per the G8 precedent -- plan unchanged
at 6/1/0 -- then applied: 6 applied, 1 skipped, 0 errors, every create READ BACK
on its intended vlan. MAAS subnets 18 -> 24, v6 1 -> 7.
Each v6 plane landed on the SAME vlan as its v4 twin, so the plane is genuinely
dual-stack on one L2 rather than a parallel fabric. The provider GUA VIP /64 was
deliberately not created -- it holds hacluster-managed API VIPs, not node
addresses, so MAAS never allocates from it.
Idempotency proven LIVE rather than only in fixture: --commit ran twice (the
second to read the script's true exit code rather than a pipeline's) and the
post-state carries zero duplicate CIDRs.
Nothing else moved: 18 Ready + 2 Deployed unchanged, no node touched, no tfstate
involved, dc1 still measures 6 v6 planes absent. The gate now reports dc0's six
v6 planes [ok]; its remaining reds are the 12 unreserved D-134 bands.
Changelog item 9 carries the revert, with the 2026-07-21 pod-delete cascade
lesson attached: read occupancy BEFORE deleting a subnet.
