Build the PKI backup path: three surfaces asserted a backup set that did not exist ...

Operator direction: back up to the per-DC jumphost creds folder BEFORE the cert cleanup, and
record that the pinned secrets-storage solution must carry a certificate/credential backup
procedure with this step folded into it.

THE GAP, MEASURED. phase-01:594 said the workspace must be "backed up securely", :605 said it
"MUST be in the per-DC backup set", and CURRENT-STATE said the inner tfstate should be added to
"the site backup set" -- while cloud-snapshot.sh, the only candidate, is a juju-layer capture
that mentions octavia, tfstate and terraform ZERO times. Both DCs' 10-year amphora trust roots
therefore sat in one place on one VM with no copy. Losing the issuing CA key means Octavia can
never sign another amphora certificate; losing the controller CA key means the controller
certificate can never be reissued, which F9 says it must be at Stage 7.

SHAPE: one gzipped archive per DC rather than a file-by-file tree copy -- 2 register rows instead
of ~20, atomic (a half-copied tree is the dangerous state), and sha256-verifiable. The live tree
on the headend stays what octavia-pki.sh verify asserts; the archive is recovery only.

COST STATED RATHER THAN GLOSSED: a second at-rest copy of both encrypted CA keys beside their
plaintext passphrases, so the archive's contents defeat encryption-at-rest. That is the trade
D-109 option (b) was refused for; the distinction is deliberate, because that ruling governed
where the authoritative artifact lives and which host the deploy reads. A recovery copy is not a
second source of truth.

Delivered: phase-01 step 1.0-GEN.e (build on the headend, pull to the per-DC creds folder,
compare sha256 against the source BEFORE removing the staging copy -- a truncated scp would
otherwise leave a verified-looking backup of nothing); 2 register rows, custody=consolidated
since the creds folder is the SEC-009 location; notes key n-pki-backup.

THE REGISTER CAUGHT AN INCOMPLETE CHANGE OF MINE: adding rows raised S2 EXPECTED-BUT-ABSENT
twice, because the per-site manifests are DERIVED from the matrix and I had not re-rendered them.
Rendered rows appended to both; S3 render drift clean, findings back to the pre-existing 7.

Standing forward requirement recorded in the register rather than as a runbook comment: the
pinned secrets-storage solution must include a documented process and procedure for certificate
and credential backup, and this step is one of the steps that must be folded into it. The
jumphost creds folder is the interim home only.

Still not backed up and out of scope here: the two inner terraform.tfstate files on the headend
-- gitignored, untracked, state-of-record for 20 VMs, and named as owed to the same backup set
that has just been shown not to exist.

Register 97 rows / 24 octavia rows. Gauntlet ALL GREEN (89), repo-lint 0 fail / 621 files.

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.

SEC-020: MAAS admin-account recovery -- consolidate `admin`, mint `operator`, creds-audit CLEAN x3 ...

Operator task: recover the MAAS admin accounts and save the creds retrievably.
The task premise was FALSIFIED by measurement before any mutation: the ledger's
2026-07-25 "MAAS web-GUI login does NOT exist / never minted" was wrong. The
`admin` password was minted 2026-07-13 by site-headend-install.sh:452 and is
MEASURED working (login 204 vs 400 wrong-password control). It was merely
root-only on voffice1 and un-consolidated -- the SEC-009 miss class, not a
missing account. Scope re-ruled by the operator after that finding:
"New account + consolidate only" -- no existing password rotated.

- NEW MAAS superuser `operator` for human GUI login; password generated on
  vcloud, set via stdin (never argv -- SEC-018 discipline; changepassword has
  no --password and createadmin --password would expose it).
- `admin` password CONSOLIDATED byte-identical (sha256-verified) to
  ~/vr1-office1-creds/. NOT rotated, so the VM copy REMAINS source-of-record;
  a future rotation must update both or the VM copy becomes a stale trap.
- juju-vr1-dc0/dc1 untouched BY RULING: their SEC-018/019 API keys are
  load-bearing for the blocked Stage-5 bootstrap.
- Manifest backfill -> creds-audit CLEAN on all three sites (was RED: dc0 3 +
  dc1 1 undeclared), closing the dc0 edge-keypair queued finding named in
  vr1-dc1.manifest:18-20.
- Root cause recorded: `admin` doubles as the automation identity (19 `maas
  admin` call sites in 4 scripts), so automation never needed the password and
  nothing forced it into the folder. Proposable as the next-free D-number
  [ARCH]; NOT assigned (GA-R3 doubt-resolves-DOWN).
- Falsified ledger claim struck+corrected; machine-derived block re-seeded
  (was stale on every line: SEC 12->16, next-free D 133->137, DOCFIX 200->204).

Evidence: docs/audit/maas-admin-recovery-20260725.txt (generated, no secret
values; scanned for password bytes = 0 hits with a planted-control check).
repo-lint 0 fail; gauntlet ALL GREEN (79).

DC0 deploy-readiness handoff: per-env-key ruling implemented + netem ruled + prep checklist ...

Prep for a fresh session to run the Stage-3 Phase-2 DC0 build. Nothing applied;
the outer tofu apply remains the first (operator-gated) mutation.

Per-env-key (D-126, operator ruling 2026-07-16, option a): vvr1-dc0 gets its OWN
access key, not office1's. Minted ~/vr1-dc0-creds/vr1-dc0_svc_ed25519 (creds-audit
CLEAN); added variable vr1_dc0_ssh_pubkey_path; vvr1-dc0 cloud-init now installs the
dc0 pubkey (voffice1 keeps office1's key -- only the vvr1_dc0 block changed). Re-
validated + re-planned: outer plan UNCHANGED at 5 add / 0 change / 6 destroy (the
cloud-init edit is create-only content, no new destroys/replaces of live infra).

netem (D-100 gap #11): RULED = placeholder for the rehearsal; final values deferred.

docs/dc0-deploy-readiness.md (NEW): the full readiness state (outer plan verified
safe -- vvr1-dc0 416GiB/108vcpu, 6 empty-plane relocation, 980GiB RAM headroom),
remaining prep (pre-apply / mid-deploy / non-blocking), fresh-session bootstrap, and
the gated A-E deploy sequence. Ledger points at it.

Gauntlet ALL GREEN (65 harnesses incl. the 2 new access harnesses); repo-lint 0-fail;
opentofu-validate clean (both roots + 12 modules). The dc0 private key + local tfvars
stay gitignored/off-repo.

D-126: durable rootless agent access to VR1 site VMs (shell + forward) + DC creds prep ...

Establishes durable, rootless jumphost->site-VM access so the recurring
sudo-route friction stops (and generalizes to the DCs). Operator ruled Option A
(SSH via systemd --user / ssh_config ProxyJump), advisor-conferred.

Shell layer (FOUNDATION, EXERCISED): scripts/site-ssh-config.sh generates
~/.ssh/config.d/vr1-sites ProxyJump aliases (voffice1, office1-netbox,
office1-tailscale, office1-opnsense). All four aliases proven live from the
agent's session after the operator installed with the one-key office1 env key --
key read from IdentityFile, no creds path in any command (clears the guard hook).

Forward layer (convenience, reviewed-but-unexercised): scripts/site-forward.sh
holds a systemd --user SSH local-forward -> http://127.0.0.1:8000 for office1-netbox.

Secrets boundary: the key is operator-supplied via --key (a PATH, never read/baked);
generated fragments name that path and are written locally (not committed).

DC prep: per-env-key isolation (operator ruling) -- each DC gets a DEDICATED key in
its own ~/vr1-dc<N>-creds/ folder, minted at deploy. Folders pre-created (0700);
creds-manifests/vr1-dc{0,1}.manifest declare the keypairs. DC ssh aliases deferred
until their IPs are measured post-apply.

Also: D-124 dc0 rack tfvars written locally (opentofu/d124-rack.auto.tfvars,
gitignored) -- the independent `tofu plan` unblocker. vr1_dc1_rack_* NOT written
(no ruled dc1 addressing; variables absent) -- STOP flagged for an operator ruling.

Tests: site-forward 38/38, site-ssh-config 30/30; repo-lint 0-fail (1 legacy WARN).
