set-interface-v4: reload the pf filter on --commit (RULED); appendix-A rewritten ...

RULING (GA-R5) 2026-07-27. Question as presented: (a) add `configctl filter reload` to the
script's --commit path; (b) leave the script and rely on DC standup DoD item 8; (c) put it behind
an opt-in flag. Operator answer, exact utterance: "a". OPS under GA-R3 -- a script fix completing
an already-documented operation, governed by D-113; no new D-number.

DEFECT (appendix-A, measured on the fresh dc1 edge 2026-07-23): --commit ran `configctl interface
reconfigure`, which applies the address to the kernel but does NOT regenerate the pf ruleset, so
OPNsense never creates its automatic outbound-NAT rules for the (re-)addressed LAN. Forwarded LAN
packets left the WAN un-NAT'd and replies never returned -- the edge passed NO LAN traffic while
looking perfectly configured. Self-masking: any later plugin install or config apply reloads the
filter as a side effect, so dc0's 07-20 qga work hid it there until dc1 exposed it.

Option (b) rejected on evidence, not taste: DoD item 8 already existed and did NOT fire at dc1,
and prose-only controls have a measured failure record here (D-137's own enforcement sat as prose
at phase-3:498 and missed BOTH DC standups).

PLACEMENT IS THE SUBSTANCE OF THE FIX, and my first attempt got it wrong -- caught before
shipping. Putting the reload on the next line of the `interface reconfigure` heredoc would have
been a fix that fixes nothing exactly when it matters: re-addressing the interface you arrived on
drops the session DURING the reconfigure, so a following command in that stream never executes --
and that drop case IS this incident's own scenario (dc1's LAN moved 192.168.1.1 -> 10.12.64.1
over the LAN itself). As shipped the reload runs over a FRESH connection to PROBE_HOST.

Also added a `pfctl -s nat` read-back with the `proto carp` boilerplate filtered out, since
boilerplate-only is precisely appendix-A's broken-state signature. REPORTED, not gated: an edge's
first addressing may legitimately have no gateway and so no NAT to generate, and hard-failing
would block a correct run. The hard gate stays address-on-the-kernel.

Harness 59/59 (was 53), cases 15-15f. Case 15f caught a real inconsistency -- appendix-A still
said "not yet ruled". Case 15e caught a bug in my own first draft, which scanned to EOF and so
failed the script for having the very hard gate the case exists to preserve.

appendix-A rewritten: the FIX stays for an edge already in this state, plus a PREVENTED-IN-THE-TOOL
block recording the placement detail and why prose prevention was rejected.

Gauntlet ALL GREEN (81), repo-lint 0-fail. No live edge touched -- both DC edges are already
addressed, so this affects only the NEXT edge addressing.

With this, every substantive Stage 4 in-stage item is closed or split to gate row G17; only the
GA-R6 close-out set remains.

Revert: git revert this commit's script + harness + appendix-A changes.

dc1 full mirror REMOVED (D-135 amendment); dc-cache-proxy.sh now owns its net layer ...

Operator clarified intent, exact utterance: "DC0 is the test of a full mirror. DC1 is the test
of the mirror proxy. DC1 needed the partially created full mirror and associated
script/files/settings removed." Recorded as a D-135 AMENDMENT 2026-07-27 -- the per-DC split
is the DELIBERATE EXPERIMENT, not an interim state. That supersedes both the "PAUSED ... kept
dormant as the fallback" record and the "DC1's proxy is REPLACED by a full mirror afterward"
claim, which sat in THREE places (D-135, CURRENT-STATE:109, dc-cache-proxy.sh:6); all corrected.

dc0 FIRST (gated): sync re-run -> OK 2026-07-27T08:43:46Z ubuntu=0 uca=0 in 20s, confirming
the transient-500 diagnosis. The fixed check now reports PASS -- trustworthy precisely because
the same check FAILED on the same rack twenty minutes earlier. Stage 4 DoD bullet 5 is now MET
for both DCs (dc0 mirror PASS, dc1 proxy PASS), node-side half at G17.

WHY THE ORDER MATTERED. Asked to weigh rip-down-and-rebuild against surgical removal, the
rebuild path turned out to be BLOCKED, not merely slower: dc-cache-proxy.sh did not own its
utility net layer -- it REUSED dc-mirror.sh's <site>-mirror-net.service and refused to install
without it. So on dc1, whose ruled path is the PROXY, three files named dc1-mirror-* (net unit,
apply helper, resolved DNS drop-in) were load-bearing FOR THE PROXY. Consequences: the recorded
removal procedure would have silently killed the proxy, the bullet-5 PASS and the Stage-5 dc1
apt path; and the proxy could not be REBUILT afterward, since nothing but `dc-mirror.sh
install` created the net layer -- rebuilding a PROXY meant reinstalling the whole MIRROR
apparatus, enabled daily debmirror timer included. Operator direction: net layer first, then
rip it all down.

1. NET LAYER MOVED: <site>-cache-proxy-net.service + -net-apply + its own resolved drop-in,
   reusing dc-mirror's proven mechanism (bridge from the libvirt net NAME at runtime, hard
   rule 3). Proxy-named so a proxy-only DC has NO mirror-named dependency. Idempotent
   replace verbs, so both net units coexist safely where a site runs both -- dc0 unaffected.
   check asserts the ARTIFACTS, not just the live address/route: asserting only the live
   effect would PASS while the layer was really the mirror's, which is the exact failure.
   Harness 20/20 (was 15). T12 REPLACED not deleted -- it asserted the superseded design, so
   it failed by design; now inverted, plus T12b-T12f. T12b is scoped to non-comment lines on
   purpose: the header's account of the removed trap cites dc-mirror.sh install, and deleting
   that history to satisfy a grep would lose why the trap existed.
2. INDEPENDENCE PROVEN BEFORE DELETING: a oneshot with RemainAfterExit=yes does not undo its
   work on stop, so stopping the mirror unit would have proven nothing. Removed the live state
   outright (addr count -> 0, default route count -> 0), applied the proxy-owned unit ALONE,
   both restored; check dc1 PASS with dc1-mirror-net.service disabled.
3. WHOLESALE REMOVAL: all mirror units, timer, sync helper, nginx vhost, resolved drop-in, the
   debmirror package, and 330G of partial mirror (33,037 files, rm -rf 47.6s; disk 339G ->
   9.0G). Zero mirror-named residue, every proxy artifact present, proxy PASS throughout and
   never down. Capture docs/audit/dc1-mirror-teardown-20260727.txt.

nginx left installed deliberately: a mirror prereq, but with the vhost gone it is a generic
server on its stock default vhost; removing the metapackage while nginx-core runs is a
half-measure and a full purge is scope creep on a rack host.

Gauntlet ALL GREEN (81), repo-lint 0-fail, dc-cache-proxy 20/20, dc-mirror 24/24.

Revert: `dc-mirror.sh install dc1` (needs debmirror reinstalled) then `sync dc1` to re-pull
~950G; git revert dc-cache-proxy.sh + harness to restore the mirror-owned layer. The 330G
partial is NOT recoverable -- deliberately, per the amendment.

Stage 4 close-out: fix dc-mirror.sh check false-greening the mirror gate ...

Operator directed closing Stage 4 before resuming the DC1 Stage-5 chain. Verifying the DoD's
fifth bullet ("per-DC mirror reachable") found that the check the gate would close on COULD
NOT FAIL.

scripts/dc-mirror.sh:271-273 tested `[ -f last-sync.status ]` and printed the file's contents
behind an unconditional "OK" -- the status word was displayed but never asserted on, so the
check exited PASS regardless. MEASURED on both racks:

- dc0 read "FAIL 2026-07-27T00:54:54Z ubuntu=255 uca=0"      -> printed OK, PASS
- dc1 read "RUNNING 2026-07-23T21:49:35Z", four days stale,
  left by the debmirror the D-135 amendment killed by signal -> printed OK, PASS

GA-R6 requires a stage to close on a NAMED executable check whose captured output the closing
commit cites. A check that cannot distinguish "synced" from "failed" or "died mid-run" is not
that check.

FIXED: the status word is case-analysed. OK* passes. FAIL* misses. An ABSENT file misses (it
was a passing `note`, but nothing has attested the content). An unrecognised word REFUSES
instead of defaulting to success. RUNNING* is deliberately neither pass nor plain fail --
in-flight and died-mid-run are indistinguishable from the file alone, so it reports an explicit
UNKNOWN and cross-checks the unit, naming a RUNNING marker with no active unit as a corpse.

Harness 19 -> 24; T20-T24 lock each status word and T24 locks out the return of the exact
defective shape.

PROOF, re-run against both live racks -- the gate is now honestly NOT MET for the first time:
dc-mirror check (dc0): FAIL / dc-mirror check (dc1): FAIL. Capture
docs/audit/stage4-mirror-gate-20260727.txt.

SUBSTANCE (measured, not inferred):
- dc0's mirror CONTENT is complete: 949G ubuntu + 342M cloud-archive, all three dists plus
  pool. Only the overnight INCREMENTAL failed -- "Download of dists/jammy/Release failed: 500
  read timeout" aborted the ubuntu leg with 255; the UCA leg succeeded. Transient upstream
  fetch failure, not mirror damage. Timer re-arms 2026-07-28 00:14:48.
- dc1's PROXY -- its RULED artifact path per the D-135 amendment -- checks PASS genuinely
  (apt-cacher-ng on .4:3142 serving archive + UCA Release 200). Its dormant fallback debmirror
  is dormant only ACCIDENTALLY: the timer is `enabled` with an EMPTY next-elapse because the
  unit sits in failed/Result=signal, so the ruling is enforced by nothing and a reset-failed
  would re-arm a 330G -> ~949G pull.

ALSO RECORDED, not yet actioned: DoD bullet 6 ("NTP from the DC's own OPNsense edge") is STALE
and unsatisfiable -- superseded by D-129(iv) 2026-07-21 ("Keep MAAS hierarchy", no NTP role on
the edge) -- and survives in four surfaces needing a DOCFIX before it can be checked at all.
The node-side half of bullet 5 needs an operator decision (gated rescue-boot check vs its own
gate row per GA-R6 E3); nodes are powered off by the READY-handoff ruling, so no node-side
probe can run as things stand. There is no conditional close.

No live state was altered: both racks were read only. repo-lint 0-fail, dc-mirror 24/24.

Revert: git revert the scripts/dc-mirror.sh + tests/dc-mirror/run-tests.sh changes; the check
returns to passing unconditionally on last-sync.

creds consolidation batch: SEC-021(b) dc0 power key, SEC-025 NetBox GUI, V2 ruled deferral ...

Operator asked whether vcloud holds a consolidated set of login creds for every account that
exists, and what is missing / needs creating / was never moved in. Audited, then cleared the
consolidation batch on operator direction ("clear the whole consolidation batch first").

The audit's own headline: creds-audit read CLEAN on all three sites while the matrix returned
13 findings -- and the two most consequential gaps were in NEITHER surface. They were found by
enumerating the accounts that ACTUALLY EXIST. Absence of a ROW is invisible to the register,
which generalises D-137's founding argument one level up.

VERIFIED POSITIVE (both previously only asserted):
- MAAS account set COMPLETE: all 6 live accounts accounted for; admin + operator passwords on
  vcloud, juju-vr1-dc0/dc1 random+unstored BY RULING with API keys present, MAAS +
  maas-init-node MAAS-internal.
- tier-3 V1 now MEASURES maas-admin-password byte-identical to the headend source-of-record,
  so SEC-020's stale-trap risk is clear as of this date.

DONE:
- dc0 SEC-012 power key consolidated to vcloud + .pub DERIVED (SEC-021(b) as written).
  MEASURED FIRST, because the naming looked like a defect and was not: the headend
  maas-virsh_ed25519 and the snap's id_ed25519 are the SAME key; it IS dedicated (distinct
  from the dc0 service key, which is what SEC-012 requires); and dc0 using the snap's default
  identity is SEC-016's RULED design. So no re-mint, no live power path touched.
- dc1 svc .pub backfilled to the headend store (public-key material, sha256-verified).
- NetBox web-GUI admin password consolidated -- a HUMAN login that had never left the VM it
  was minted on, the third instance of the SEC-009/SEC-020 miss class. SEC-025 OPENED for the
  at-rest exposure the copy CREATES, not the gap it closed. Open rows 20 -> 21.
- V2 taught the ruled-deferral state: SEC-006's standing "revoke at completion of this
  deployment" ruling is now ACKNOWLEDGED (still naming the credential live and exposed)
  instead of failing every run. Reissuing the token would have CONTRAVENED that ruling, so the
  register was what needed to change. Match demands the cased state word AND explicit operator
  ruling attribution, and cannot cross a ledger table cell -- T58/T59 lock the evasion out.
- Added --ledger (default unchanged): V2 read the register via --repo, which the harness must
  point at the real repo for S4, so V2 had shipped with ZERO harness cases. T56-T59 added.

Findings 13 -> 7. Matrix 82 rows, harness 60/60 (was 56), creds-audit CLEAN x3, gauntlet ALL
GREEN (81), repo-lint 0-fail. The register is NOT green and is not expected to be.

RESIDUAL, all recorded: dc0-edge-api x2 (the opnsense-api.txt re-mint is a live edge mutation,
deliberately EXCLUDED from this batch), S5 x3 (RULED by SEC-016 -- needs a ruled-exception
mechanism, operator decision), S6 conflation x1 (the SEC-020 defect), E4 x2 (Stage-5/6 rows).

LOGGED NOT ACTIONED (hard rule 1): no registered root/console credential at EITHER DC edge
(measured absence of row/manifest/SEC row; what those passwords ARE is UNKNOWN and
deliberately unprobed per hard rule 2 -- vector is the LAN-reachable GUI and serial console,
not SSH, which is key-only and proven); plus the two structural blind spots that let it hide
-- S5 compares only cardinality=per-DC while all six per-site rows are office1-only, and
vm-secret-locations declares no rack/edge/cloud/unit/client location though the checker
accepts them.

Revert: per-item reverts in docs/changelog-20260727-creds-consolidation.md. The headend, snap
and NetBox VM source copies were never modified, so every file move is reversible by deletion.

D-137 tier 3 behavioural half: V2 declared-state + creds-probe.sh ...

Boundary and cadence operator-ruled: "Full -- including OpenStack service
credentials", "Stage close + DC standup close". I had recommended
passive-only and flagged the costs; the operator ruled otherwise.

V2 (passive, zero authentication) fires TODAY on a real defect: SEC-006 has
recorded the NetBox upstream token as BURNED since 2026-07-12 while the
matrix carried it as a healthy consolidated row. Nothing reconciled the two
surfaces. Keyword matching on ledger prose is fragile, so it is conservative
and reports the matched text as its basis.

creds-probe.sh is SEPARATE by design: a probe must USE a credential, and
creds-matrix.py is metadata-only by an enforced invariant (T22/T51). Folding
probes in would have relaxed that guard, and a guard relaxed once stays
relaxed.

Safety: never retry a failed auth (retry loops lock accounts; the MAAS admin
identity backs 19 call sites), never argv, never echo, stage-aware skips, and
per-tenant credentials REFUSED BY CONSTRUCTION -- a declaration cannot opt
them back in (D-069, ruling 3). Not a deploy gate.

FALSE GREEN in my own first run: ssh inside a while-read loop ate the loop's
stdin, so 1 of 13 probes ran and the run exited 0. A partial run reporting
clean is the exact failure class this tool exists to catch. Fixed with ssh -n
and locked by a total-accounting check that makes a partial run VOID.

13 probes declared: 3 active, 4 stage-pending, 6 declared-only with reasons
recorded. OpenStack credentials declared now, skipping until Stage 5.

tests/creds-probe 9/9; gauntlet 80 -> 81; phase-3 DoD wired.

D-137 tier 2: local half blocking in P5; --pending-stage -> coupled projection ...

Two operator decisions, both taking the recommendation.

GATE SHAPE: local-only blocking, remote operator-run. preflight P5 now runs
creds-matrix.py --tier2 -- tier 1 STATIC plus tier 2 LOCAL, hermetic (no ssh,
no sudo). It already catches SEC-021's three dc0 on-disk absences without
leaving the jumphost. The remote half stays an operator-run check at
DC-standup close and stage close.

Wiring --remote --privileged into the deploy gate would let a host outage, a
NOPASSWD change, or a MAAS snap refresh turn the gate red for reasons that
are not about credentials, and a gate that fails environmentally is one
people learn to bypass. The repo already made this call once
(run-tests-all.sh:7-8, "different cadence"), and preflight already shows the
failure mode: P4 reads "MAAS unreachable" because it runs on vcloud while
MAAS lives on the headend.

STAGE INPUT: --pending-stage replaced by creds-manifests/stages-reached, a
machine-readable projection of CURRENT-STATE, coupled by new repo-lint L12
(the L10 pattern). A hand-typed gate parameter can be widened silently, and
GA-R1 puts status in CURRENT-STATE alone. A drifted projection would make the
gate defer REAL absences -- a false green.

Exhaustive both ways: an unclassified mint-stage is a hard FAIL, a
classified-but-unused one is a stale-declaration FAIL. That caught `stage4`
immediately -- Stage 4 is open and executing but mints no credential.

Self-inflicted break caught by the existing harness: I first renamed L10's
message to "L10/L12", breaking five cases that grep the established L10 id.
Reverted -- new rules get their own message id, they do not rebrand old ones.

Harnesses: creds-matrix 52 -> 56, repo-lint 45 -> 47, preflight 10.
Gauntlet ALL GREEN (80), repo-lint 0-fail, baseline unchanged.

D-137 tier 3 (VALIDITY) BUILT: cross-copy sha256 provenance ...

Closes the gap the plan names: creds-audit PARSES declared provenance and
never verifies it, so SEC-020's stale-trap warning has been unchecked prose
and its sha256 equality was a ONE-TIME manual act on 2026-07-25.

sha256sum runs as an EXTERNAL command on both sides so only a 64-hex digest
enters the checker -- hashing bytes in Python would meet the letter of "never
transfer content" and not the spirit.

RESULT: 4 groups compared, all byte-identical, INCLUDING the SEC-020 pair
(maas-region-admin, region source-of-record vs jumphost copy). Now
machine-verified instead of remembered. The [ok] line names the groups.

TWO FALSE POSITIVES IN MY OWN DRAFT, caught by verifying before reporting.
Keying digests by (role, site) let an identity's DISTINCT artifacts at one
scope overwrite each other, so it compared unrelated files and reported drift
on maas-region-admin and dc1-svc-key. Manual sha256sum showed both IDENTICAL.
Reporting that would have raised a false credential-rotation alarm.

Root cause was a schema gap: nothing expressed which rows are byte-copies.
custody gains `verbatim-copy` [OPS]. V1 now compares only rows sharing
(id, filename) across scopes, or a source-of-record row against declared
verbatim-copy rows -- SEC-020's exact shape. Everything else is skipped with
a reason: a pair we cannot justify comparing is not a pair we may report
drift on. verbatim-copy is manifest-bearing; it asserts byte-identity, it
does not move the file.

Harness 44 -> 52: T47/T48 regression-lock both false positives; T49 keeps
SEC-020's case from falling into T48's skip; T51 asserts the digest path uses
sha256sum and that no content-transfer verb exists anywhere in the checker.

NOT built: tier 3's behavioural probes. Liveness, expiry, revocation state
and grant/scope drift remain unverified.

Gauntlet ALL GREEN (80), repo-lint 0-fail, finding-class baseline unchanged.

D-137 ruling 1 EXECUTED: tier 1 wired as the blocking preflight P5 ...

Operator answer, exact utterance: "wire tier 1 as the blocking preflight Pn"
(2026-07-26), resolving the open sequencing question. Recorded on D-137.

preflight.sh gains P5: credential matrix (D-137 tier 1), blocking, with
worst-exit aggregation, placed AHEAD of the stage-2 reminders block (now P6)
so its verdict participates in the deploy decision. Tier 1 only -- it is
offline and its findings ARE the three ruled failure classes. Tier 2 needs
--remote/--privileged and a caller-supplied --pending-stage, which do not
belong in an unattended gate; that stays an open decision.

FAIL-OPEN in my own wiring, caught by the new test: a missing creds-matrix.py
makes python3 exit 2, which `note` maps to WARN -- so deleting the gate would
have downgraded it to a warning rather than stopping the deploy. P4 already
guarded this class; P5 did not until T9 failed. Now guarded explicitly.

tests/preflight 7 -> 10: T8 a red register FAILS the deploy (blocking, not
advisory); T9 fails closed when the checker is absent; T10 the gate runs
before the reminders block.

CONSEQUENCE, not overclaimed: preflight exits 1 with P5 among the reasons,
but preflight was ALREADY exiting 1 before this change (P4: octavia-pki.yaml
absent, MAAS unreachable from the jumphost). P5 adds a fifth reason to an
already-red gate; it flipped nothing and closes no open deploy path.
Verified by stashing the change and re-running.

Gauntlet ALL GREEN (80), repo-lint 0-fail.

D-137 phase 3: re-measure the register; SEC-024 opened ...

~21 inferred filenames corrected against their own mint-refs. The session had
owned six; those were only the rows the first sweep physically touched.
Octavia's 8 real basenames plus its THREE SUBDIRECTORIES (the bare
~/octavia-pki/* pattern matched ZERO of the 8 artifacts, two of them CA
private keys); vault's init.txt; the tenant rows' <client>- instance prefix,
with a placeholder matcher so they can match a real basename at all;
kube-config -> config; .maas.cli -> .maascli.db (measured: ~/.maas.cli does
not exist).

sec-ref mis-attribution corrected: both juju-maas-user rows cited SEC-020;
the on-subject rows are SEC-018/-019. This is the SEC-015 class recurring --
one instance was fixed by hand earlier without checking whether it was
systemic. It was.

mint-ref corrected: admin.pass cited a CONSUMER (:452), not the mint (:450);
the RGW key cites a line that takes it as INPUT, so it is operator-terminal.

Rows added: the libvirt SSH power password (standing rotation obligation from
a 2026-06-26 plaintext exposure, in neither the matrix nor the exclusions),
vault-ca-root, and the tfstate siblings. ~/as-executed/ deliberately NOT
declared, reason recorded: it holds session logs, so declaring it made every
log a false UNDECLARED.

Four further defects in my own phase-2 changes, found by RUNNING the sweep:
shlex.quote broke ~ expansion; a non-existent parent read as unreadable
rather than absent; site-key `-` needed shared-location semantics; the
tfstate siblings needed rows.

SEC-024 OPENED -- new exposure found by the fixed checker on its first clean
run: opentofu/terraform.tfstate.backup is mode 0664 and carries the MAAS API
key in plaintext (DOCFIX-175); the live state file is 0600. Invisible to
every prior control because the world-readable check was custody-gated and
the siblings were undeclared. LOGGED, NOT ACTIONED (hard rule 1).

Findings 35 -> 13, all true. Matrix 81 rows. Harness 44/44, creds-audit
15/15, gauntlet ALL GREEN (80), repo-lint 0-fail.

D-137 phase 2: fix the eight confirmed false-greens, regression-lock each ...

Tier 2 is now scoped by (host-role, SITE-KEY). Keying on role alone merged
all three jumphost creds folders into one basename namespace, so a credential
present at ANY site satisfied the row for EVERY site -- how SEC-021's dc0
opnsense-api.txt absence passed a green sweep while tier 1 flagged it. Four
committee lenses converged on this. vm-secret-locations gains a site column.

Also fixed, each reproduced by the committee and each now regression-locked:
- probe_remote called a successfully-read location UNREACHABLE when its glob
  matched nothing, gating the role and turning every absence FAIL there into
  an [ok]; a __DONE__ liveness marker now separates "ran, found nothing" from
  "could not reach".
- literal-file locations skipped absent/unreadable detection entirely (the
  T33 false green surviving in the other path form).
- an EMPTY locations list bypassed ruling 3's refusal.
- a zero-row matrix reported clean over the empty set.
- a mint-ref pointing at a directory crashed with exit 1 -- indistinguishable
  from findings -- and skipped S5/S6/S7, silently dropping the conflation and
  asymmetry findings.
- mode enforcement was custody-gated, leaving 43 of 77 rows unchecked
  including the SEC-020 and SEC-022 stores; a world-readable check now
  applies at any custody.
- S5's dc1->dc0 direction was untested; deleting it left the harness green.
- rows with no declared location for their scope are disclosed, not skipped.
- declared paths/targets are charset-validated and shell-quoted: an
  unvalidated `;` reached a remote shell, under sudo when --privileged.
- creds-audit sprawl globs now cover dotfiles; the prior widening could not
  see .admin.pass, the dotfile sibling of its own motivating secret.

T24 replaced with a checked-in finding-CLASS baseline. The old form grepped
for the literal "IDENTITY CONFLATION", so REMEDIATING that defect would have
turned the gauntlet red for whoever did the right thing -- making "edit the
test" the cheapest response exactly when the guard mattered.

Harness 35 -> 43, creds-audit 13 -> 15, gauntlet ALL GREEN (80), lint 0-fail.

D-137 tier 2: live read-only sweep + two probe false-greens it exposed ...

SEC-021's ON-DISK half REPRODUCED: vr1-dc0-maas-power_ed25519{,.pub} are
genuinely absent from the dc0 jumphost creds folder, not merely undeclared.
Capture: docs/audit/d137-tier2-sweep-20260726.txt (read-only, no sudo,
stat-over-ssh metadata only; jumphost + voffice1 + office1-netbox).

Running it against real hosts exposed two false-greens in the probe:

1. "absent" vs "could not look". /root/maas-secrets and /root/netbox-secrets
   reported "does not exist" -- they exist; SEC-020 is precisely about
   admin.pass living in the first. An unprivileged [ -d ] on a root-owned
   parent is indistinguishable from a missing directory. The probe now tests
   parent traversability and reports UNREADABLE as a FAIL, not a skip.

2. Role-level aggregation manufactured false absences: skipping one location
   let a role's other locations cover it, so credentials in the unprobed
   location reported EXPECTED-BUT-ABSENT. Absence is now asserted only over
   fully-probed roles (14 rows report NOT JUDGED). Refinement: "absent" is a
   conclusive observation and does not gate a role; only unreadable and
   unreachable do.

Harness 33 -> 35 (T33 unreadable location, T34 absent location).
Gauntlet ALL GREEN (80), repo-lint 0-fail.

OUTSTANDING: the two root-owned dirs need a privileged read, so SEC-022's
shadow-store contents and the SEC-020 region secrets stay UNCONFIRMED. That
is a remote-sudo shape and was not run.

D-137 tier 2 (EXISTENCE): declared-location bound, existence checks, widened globs ...

Tooling only -- the LIVE three-site sweep has NOT run, so SEC-021's on-disk
half, SEC-022 and SEC-023 are not yet reproduced as live findings.

creds-manifests/vm-secret-locations (ruling 3): the absolute bound on
discovery. Covers the jumphost creds folders, the SEC-022 headend shadow
stores, the SEC-020 region secrets dir, the three dirs outside the SEC-009
convention, plus two the ruling's note did not name -- the in-clone PKI
overlay and the DOCFIX-175 plaintext tfstate. Tenant dirs are LOCAL-only:
no tenant VM/project/host is reachable from this file, so D-069 holds by
construction rather than by good behaviour. `<repo>` is substituted at
runtime (D-110: the repo name is never hardcoded).

creds-matrix.py --tier2 [--remote]: E1 expected-but-absent, E2 mode, E3
undeclared-at-a-declared-location. Probes are `stat` over ssh -- metadata
only, never content. An unreachable host SKIPS with an explicit [ok],
because "could not look" must never read as "nothing there".
--pending-stage is supplied by the CALLER so a not-yet-reached mint stage
defers instead of failing; encoding which stages have run would put a
status claim in code, and GA-R1 puts status in CURRENT-STATE only.

creds-audit.sh sprawl globs widened for the SEC-023 blind spots
(admin.pass, *.apikey, *.key, *.pem, *_ed25519, *_rsa, *openrc*). The old
six patterns could not have matched the SEC-020 secret that sat undetected
12 days, any bare SSH key or PEM, or the predicted Stage-5 ~/admin-openrc.

Harnesses: creds-matrix 33/33 (8 new tier-2 cases), creds-audit 13/13
(was 7; five blind-spot fixtures plus T13 asserting the widening did NOT
become trigger-happy). Gauntlet ALL GREEN (80), repo-lint 0-fail.

FLAGGED DIVERGENCE from the plan's Files list: --remote is implemented in
creds-matrix.py, not creds-audit.sh. Tier 2 IS the preflight Pn and the
matrix plus locations list both live there; splitting it would mean two
implementations of one bounded walk. Ruling 3 names a bound, not a script.

D-137 tier 1 (STATIC): credential matrix, checker, harness -- RED by design ...

Schema amended 10 -> 12 columns (operator-ruled 2026-07-26, "go with the
12-column amendment"): adds `custody` + `notes-ref` and re-keys a row to one
(credential, location) pair. A read-first round-trip check of the three
manifests proved the 10-column form could not carry what D-137 ruling 2
forbids dropping -- and ruling 3 puts four deliberate credential copies inside
--remote's declared locations, where creds-audit.sh:63-67 would report each as
UNDECLARED. Implements ruling 2 ("prose must become MATRIX FIELDS"); OPS under
GA-R3, the five sub-rulings untouched.

Ships: creds-matrix.tsv (72 rows), creds-matrix-notes.md (32 keys),
scripts/creds-matrix.py (S1 schema / S2 both-bounds manifest coverage / S3
render drift / S4 mint-ref resolution / S5 per-DC symmetry / S6 ruling-5
principal invariant / S7 notes integrity), tests/creds-matrix 24/24.
Gauntlet ALL GREEN (80, was 79); repo-lint 0-fail.

RED BY DESIGN, 5 findings -- do not go green by deleting rows: the ruling-5
identity conflation on maas-region-admin (the live SEC-020 defect), 3x
EXPECTED-BUT-ABSENT for SEC-021's declaration half, and the S5 asymmetry on
dc0's divergently-named headend power key. 27 operator-terminal rows are the
FINDING 1 reproducibility debt, counted not faulted.

Two self-inflicted false-greens found and closed during the build: S2
enumerated only matrix-mentioned sites (an empty matrix read CLEAN -- the
sandbox-fidelity-check.py:131-143 defect one level up; now the union of both
sides, regression-locked by T9), and the uniqueness key false-failed two
identities sharing one file (T6).

NOT done, stated so the boundary is unambiguous: tiers 2-3, vm-secret-locations,
the SEC-009 demotion, and the ruling-1 preflight Pn -- whose blocking-vs-deferred
sequencing is an OPEN operator question. No manifest rewritten; no cloud state
touched.

netbox: office1-record dumper (source separation) + current apex snapshot ...

Operator-directed: one dump script per SOURCE so a credential/URL can never be
confused (the token never travels -- read from env).

- netbox/office1-record-dump.py (NEW): READ-ONLY dumper for the office1-netbox
  RECORD -- the VR1 working apex (10.10.1.10:8000, 4.6.4, v2 token). This is what
  every VR1 system actually consumes (DOCFIX-195) and what the dc0/dc1 buildout
  edited -- i.e. the CURRENT in-cloud NetBox state.
- netbox/prod-draft-dump.py: docstring clarified -- it pulls ONLY the FROZEN v1
  reference (netbox.baldurkeep.com), not the working apex.
- tests/office1-record-dump/run-tests.sh (NEW): offline harness 5/5 (slim /
  prefix-scope rewrite / range key / source-target).
- netbox/draft/vr1-office1-current-20260725.json (NEW): the current snapshot --
  139 prefixes / 11 sites (incl. vr1-dc0/dc1/off1), dc1 bands 10.12.64/68/72.0/22
  present; differs from the 90-prefix frozen reference. For the Chat design
  session (NetBox->deploy coupling) which has no live infra.

READ-ONLY: nothing written to NetBox. repo-lint 0-fail.

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).

D-135 amendment: DC1 interim apt caching proxy (dc-cache-proxy.sh) ...

Operator-ruled 2026-07-24 (GA-R5, utterance quoted in D-135): DC1 gets an
interim apt caching proxy (apt-cacher-ng) to unblock its build without waiting
on the full ~950 GiB debmirror; DC0 stays the full-mirror deployment under test;
DC1 proxy is replaced by a full mirror afterward. Both artifact-delivery models
thus get exercised this rehearsal (Roosevelt input, D-132/D-133).

- scripts/dc-cache-proxy.sh: site-keyed check/install; apt-cacher-ng proxy mode
  at the D-134 utility .4:3142; reuses the <site>-mirror-net layer (fails loud if
  absent); caches archive/security/UCA, consumed via juju apt-http-proxy.
- tests/dc-cache-proxy/run-tests.sh: 15 static cases, 15/15 PASS.
- D-135 AMENDED (design-decisions.md) + CURRENT-STATE Stage-4 DC0/DC1 split.
- DC1 debmirror PAUSED at ~330 GiB (kept dormant as fallback); measured that the
  vcloud uplink was NOT the shared bottleneck (pausing dc1 did not speed dc0).

Feasibility recon'd read-only first (apt-cacher-ng installable, upstreams 200 via
edge, port free). Live install on the DC1 rack is the separately-gated mutation.

caveman: disable on live host + SEC-017 + fail-closed compress guardrails ...

Council-reviewed follow-through on the caveman plugin (operator accepted the
recommendations). Three gated deliverables:

1. DISABLED on the live host: enabledPlugins."caveman@caveman"=false at user
   (~/.claude, uncommitted) + committed repo scope; env CAVEMAN_DEFAULT_MODE=off
   retained; marketplace kept for deliberate re-enable. Stops the per-turn
   third-party hook execution (which ran regardless of mode=off) at next
   session start.
2. SEC-017 opened (docs/security-ledger.md): supply-chain re-verify obligation
   pinning SHA 0d95a81 + self-remeasured baseline hashes; register = OPS (no
   D-number per GA-R3; precedent D-129). Open SEC 12->13, reconciled at Stage 4
   close (not an L10 trigger; CURRENT-STATE untouched).
3. Guardrails: repo-lint L11 FAILs on any *.original.md (caveman-compress
   residue), opt-out marker + harness T42-T44 (45/45 PASS); .claude/settings.json
   deny on Bash(*python3 -m scripts*)+Bash(*caveman-compress*); CLAUDE.md
   "Tooling guardrails" prohibiting the compressor against any repo-tracked
   prose. Rejected the proposed plugin-hash-baseline-in-repo-lint (layering
   violation; drift belongs in the SEC-017 re-verify duty).
