D-129: build the OPNsense edge plugin profile-installer + sharpen pins ...

Autonomous processing of D-129 items that need no operator keyboard. Repo-only;
NOTHING applied to the cloud (live plugin install stays classifier-gated).

- NEW scripts/opnsense-plugins.sh + tests/opnsense-plugins/ (17/17): named-profile
  installer over the D-113 firmware API. Installs ONE plugin at a time + polls
  upgradestatus (the firmware-lock lesson), delegates auth to opnsense-api.sh,
  warns os-qemu-guest-agent != a working agent, offline --dry-run. Closes the
  "build the reusable installer" pin.
- D-129 + dc-dc-phase2 pin: installer recorded as BUILT (use it, not build it);
  qga channel logged as an OPT-IN-var design (default OFF -> no office1/DC0-plan
  side-effect; dmacvicar 0.9.8 mechanism-to-verify); os-git-backup operator ask.

D-129 verify: qga installed-but-non-functional; iperf lost to firmware lock ...

Reconcile records to the measured 2026-07-18 install verification (operator ran
the firmware POSTs via `!`; agent verified read-only). No cloud mutation here.

- os-qemu-guest-agent: package installed, NON-FUNCTIONAL -- daemon off + the
  opnsense-edge module defines no org.qemu.guest_agent.0 libvirt channel
  (guest-ping fails). Functional enablement = channel-in-module + service-enable
  + edge restart -> DEFERRED; new DC edges born with the channel.
- os-iperf: did NOT install -- back-to-back firmware POSTs collided on the
  OPNsense firmware lock. Re-run pending; profile-installer must be 1-at-a-time
  + poll upgradestatus.

D-129 partial-rule: adopt VR1 edge plugin profile + pin the rest at deploy steps ...

Operator directive 2026-07-18 ("install the recommendations + pin the rest").
Doc/runbook-only; the LIVE install is operator-gated (auto-mode classifier
blocked the agent POST) and pending verification -- no cloud mutation here.

- D-129 PARTIALLY RULED (status line kept OPEN so ledger-scan still tracks the
  4 sub-decisions: COS-edge scope, os-frr, os-tailscale, edge-NTP). VR1 profile
  {os-qemu-guest-agent, os-iperf} adopted; pinned-at-steps mapping added.
- dc-dc-phase2 (DC-edge section): pin the VR1 profile at edge bring-up + build
  the reusable opnsense-api profile-installer there.
- dc-dc-phase6 Step 10: pin os-node_exporter gated on the COS-edge scope call.

D-126 base-leg oneshot (site-baseleg.sh) + D-128 operating model; post-restart sweep ...

vcloud post-restart health sweep all-green (host on 6.8.0-136, patch+reboot done;
libvirt/pools/autostart clean; Office1 stack self-recovered end-to-end). Sweep
surfaced a recurring break: office1-local is an ISOLATED libvirt net, so the host's
base L3 leg (10.10.0.10/24 on the bridge + compose route 10.10.1.0/24 via 10.10.0.20)
lives nowhere in the XML and drops on every reboot -- the un-persisted foundation
D-126 assumed but never owned.

- NEW scripts/site-baseleg.sh + tests/site-baseleg/ (24/24): root Type=oneshot unit,
  After=libvirtd (+virtnetworkd for modular hosts; ordering MEASURED here = monolithic
  libvirtd), re-adds the leg at boot. Bridge DISCOVERED from the stable net name (never
  a baked virbrN, PATTERN-1); apply idempotent + root-guarded; check = session-verify.
  INSTALLED + enabled this session; boot-race UNPROVEN until an actual reboot.
- docs/design-decisions.md: D-126 amendment (base-leg durability) + NEW D-128 (operating
  model -- Claude on the vcloud jumphost; Plane-1 substrate on vcloud / Plane-2 executes
  on voffice1; workstation tailnet is the human path; D-107 untouched).
- Skill invariant + routing row (SKILL.md), Cross-cutting bullet (dc-dc-deployment-workflow.md),

D-127 IaC autostart matrix baked into deploy tooling + Office1 guest updates ...

Operator directive: bake the autoboot-vs-manual matrix into the IaC so DC0/DC1 get
correct autostart at creation, not by hand. Added an `autostart` bool var to modules
cloudinit-vm/opnsense-edge/node-vm (wired to libvirt_domain.autostart); set explicitly
per instance (shared modules => IaC is source of truth): voffice1=true,
office1-opnsense=true, vvr1-dc0=FALSE, vr1-dc0-opnsense=true, node-vm=FALSE.

HARD GATE verified: the two existing Office1 domains (voffice1, office1-opnsense) plan
as autostart false->true UPDATE-IN-PLACE, NOT replacement (replacement would destroy the
live host/edge). vvr1-dc0 is a new create with autostart=false baked in. Outer plan now
5 add / 2 in-place / 6 destroy; the 2 collapse to 0 once the bookend sets those two
autostart live pre-apply. tests/opentofu-validate T11-T15 pin the matrix against drift.

Standup runbook records the composed service VMs' LXD boot.autostart step. Confirmed
DC0/DC1 create NO LXD instances (inner root = node-vm + opnsense-edge + planes/pool/
wan-bridge) -- DC side is purely this VM matrix.

Office1 guest updates (agent sudo inside the guests): office1-netbox apt upgrade (no
reboot, netbox healthy); office1-tailscale full-upgrade -> kernel 6.8.0-136 + reboot
(back, re-advertising 10.10.0.0/22); voffice1 0-upgradable; LXD boot.autostart=true set
on both. vcloud + office1-opnsense stay in the operator's bookend.

D-127: VR1 host-VM autostart policy (foundational autostart, DC containment manual) ...

Recorded before a vcloud OS-update/reboot window (open now: only Office1 VMs live,
pre-DC0). voffice1 autostarts; office1-opnsense autostarts AFTER one verified post-fix
cold boot (DOCFIX-188 mem-unit fix -- the triple-fault was a fixed config bug, not live
fragility); vvr1-dc0/dc1 containment stay MANUAL (gated depth-4/site-down bring-up).
Live via `virsh autostart`; IaC layer (module autostart arg) queued. ops-restart-
procedure.md pointer added. Ledger records the post-reboot TODO (verify clean startup,
THEN set autostart) since a host reboot ends the running agent session.

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).

D-124 addressing pinned: transit supernet 172.31.0.0/24 (operator-ratified); importer CONTAINER + harness ...

Operator ruled the three dc-rack-mgmt-import.py scoping flags + ratified the
values (2026-07-16): seed a dedicated `transit` role; CARVE a dedicated transit
supernet (not Cloud) = 172.31.0.0/24; scope vr1-dc0 ("mirror the edge"); transit
/30 172.31.0.0/30; rack IP 10.12.8.2.

- netbox/dc-rack-mgmt-import.py: CONTAINER "10.12.0.0/16" -> "172.31.0.0/24"
  (+ header note, RULED scope flags, ratified usage example). Still takes
  --transit-cidr/--rack-ip as required inputs; still fail-loud on missing/
  collision container (the backstop for a block picked against a stale draft).
- tests/dc-rack-mgmt-import/{run-tests.sh,test_logic.py}: CONTAINER assertion +
  every transit fixture rebased Cloud->172.31.0.x (shapes/host-bits preserved so
  rejections still die for the right reason). 96/96 PASS.
- docs: D-124 AMENDMENT (carve + ratified addressing) + changelog-20260716-
  d124-addressing-pin.md (the exact on-host --commit sequence) + session-ledger.

NOT DONE (cannot from here): the NetBox --commit. office1-netbox (10.10.1.10) is
UNREACHABLE from the vcloud jumphost (ping/TCP:8000/HTTP all fail, no SSH/tunnel)
and the apex token is a secret on that host -- the write is an on-host operator
step. NO apex mutation in this commit.

The corrected D-125 note claimed 172.30.2.0/24 is "already registered by

edge role + 172.30.0.0/16 container are absent -- d115-office-carve not yet
committed either). Corrected: the /24 is OWNED BY that importer and PENDING its

D-125 correction: uplink /24 is the ruled 172.30.2.0/24, not a HELD tfvar (no new NetBox object) ...

The initial D-125 records wrongly modeled the vcloud ISP /24 as a NEW,
NetBox-assigned HELD value (`var.vr1_dc0_uplink_cidr`) with an OPNsense WAN
re-address. That is factually wrong: bridge-in is single-NAT, so there is
exactly ONE simulated-ISP /24 for vr1-dc0, and D-115 already ruled it
(172.30.2.0/24, role edge, site vr1-dc0). NetBox models the prefix by role+site
and does not care which libvirt host runs the NAT, so the /24's IPAM identity is
UNCHANGED from Model A; only the libvirt realization moved (a vcloud NAT bridged
through vvr1-dc0). OPNsense WAN stays .2. (Caught reconciling the "create netbox
objects" request against dc-edge-wan-import.py, which already registers this /24.)

- opentofu/main.tf: module vr1_dc0_uplink cidr = "172.30.2.0/24" inlined (ruled
  literal, matching the inner root's site-wan pattern) instead of the var.
- opentofu/variables.tf: REMOVED variable vr1_dc0_uplink_cidr (replaced with a
  note explaining why it is a ruled literal, not a tfvar).
- Records corrected everywhere the false claim propagated: D-125 body + D-122
  amendment, changelog-phaseC2-D125, model-a-fallback (B->A delta item 8 +
  revert), session-ledger, dc-dc-deployment-workflow, phase-2 runbook.

Net effect: D-125 adds NO new NetBox object and NO new HELD gate. The only
NetBox work left for the DC substrate is D-124's transit /30 + rack IP.

Both roots validate; gauntlet ALL GREEN (63); repo-lint 0 fail.

D-125: Model B per-DC ISP egress (bridge-in, single-NAT) -- resolves OBS-3 design gap ...

OBS-3: Model B nesting put vr1-dc0-wan (a libvirt NAT) inside vvr1-dc0, whose
only leg is the SEC-010 FORWARD-dropped transit -- so the per-DC simulated ISP
had no egress. Operator ruled bridge-in (single-NAT) over double-NAT.

- modules/wan-bridge (NEW): libvirt forward=bridge onto a pre-existing host
  bridge (bridge={name}, schema measured from the provider, not guessed). No
  subnet/NAT. Sibling to site-wan so every NAT user stays untouched. Covered by
  opentofu-validate S3 (standalone PASS).
- OUTER root: vcloud ISP NAT vr1_dc0_uplink (the single NAT) + a 2nd IP-less
  uplink NIC on vvr1-dc0 + the br-vr1-dc0-wan bridge declared in netplan (transit
  stays NIC1 so SEC-010/--transit-if keep keying on it). New HELD var
  vr1_dc0_uplink_cidr (no default; office1-netbox apex, hard rule 2).
- INNER root: vr1_dc0_wan site-wan(NAT) -> wan-bridge onto br-vr1-dc0-wan;
  OPNsense WAN re-addresses into the vcloud ISP /24 (edge config, D-113, HELD).
- Bootstrap (site-headend-install.sh): --uplink-if/--wan-bridge; --check verifies
  the bridge exists + uplink ENSLAVED (fail-open guard, same class as the transit
  check); SEC-010 rationale corrected (bridge-in has no inner NAT) + br_netfilter
  CONSTRAINT (keep the FORWARD-drop interface-scoped, NEVER global). Harness 49->54.

Records: D-125 (new); D-122 amendment (forward-pointer -- WAN realization
superseded, intent stands); SEC-010 (br_netfilter + hardened --check);
model-a-fallback B->A delta item 8 + revert; platform-traps 1g (bridge +
br_netfilter + nested-foreign-MAC trap).

NOT closed: the L2-NAT-of-foreign-MAC path is a DEPLOY-TIME gate (bridge-in
equivalent of the depth-4 boot gate); fallback = double-NAT. HELD: vr1_dc0_uplink_cidr
+ OPNsense WAN re-address. Both roots validate; gauntlet ALL GREEN (63); repo-lint
0 fail. Present-only; NOT pushed.

Stage-3 review sweep C+D: Model B two-root reshape + SEC-010 hardening ...

Phase C (Model B reshape, D-123 operator ruling):
- outer root (opentofu/main.tf): vvr1-dc0 resized to whole-DC containment VM
  (108 vCPU / 425984 MiB / 3221225472000 bytes; expose_nested_virt=true;
  single Office1 transit leg); node/plane/wan/opnsense modules removed from
  vcloud level (MOVED markers), storage-04 added per R-3.
- inner root (opentofu/vr1-dc0-substrate/): NEW second root, provider
  qemu+ssh to vvr1-dc0; reuses ../modules/* verbatim to build 9 nodes +
  6 planes + wan + opnsense inside the containment VM. dmacvicar/libvirt
  0.9.8 pinned (.terraform.lock.hcl committed). Both roots tofu-validate.
- variables.tf: vvr1_dc0_vcpu/memory_mib/disk_bytes with derivation comment.

Phase D (SEC-010, R3-F02): site-headend-install.sh --host-nodes node-host
bootstrap installs qemu-kvm+libvirt, persists+verifies nested=1, writes a
transit FORWARD-drop (nftables inet sec010) enforcing DC-LOCAL under Model B.
Gate hardened (advisor catch): --check now verifies the keyed transit
interface EXISTS, else nftables oifname loads clean but matches nothing
(fail-open). Harness 49/49.

Records: D-103/107/114/121/122/123/124 amendments (append-only);
model-a-fallback-plan synced; ledgers + Phase-C changelog.

KNOWN GAP (OBS-3, operator-confirmed 2026-07-16): under Model B the inner
vr1-dc0-wan NAT is nested inside vvr1-dc0 (single transit NIC), severing the
simulated-ISP egress that Model A had at vcloud level. DC0/DC1 ARE meant to
have ISP connections -- egress path resolution is follow-up design work, not
resolved by this commit.

Present-only; not pushed. Gauntlet ALL GREEN (63); repo-lint 0 fail.

Review sweep A+B + R-3 storage-04: coherent record, whole-host calculator, R-3-compliant Model A fallback ...

Phase A (record amendments) + Phase B (scripts/dc-dc-whole-host-budget.py + harness) of the
Stage-3 adversarial-review sweep, plus the R-3 storage-04 addition (Model A layout now
3+2+4 = 9 nodes/DC). This commit is the R-3-COMPLIANT Model A state and becomes the re-cut
`model-a-fallback` anchor (the prior tag at 87a7a8a was R-3-stale -- 3 storage -- flagged by
the Model B design cross-check). NO cloud mutation; nothing applied.

- design-decisions.md: D-103/D-107/D-114/D-115/D-121/D-122/D-123/D-124 amendments (rulings R-1..R-4).
- scripts/dc-dc-whole-host-budget.py + tests/ (13/13): replaces the lost optc-calc.py (R3-F06).
- opentofu/main.tf: locals.vr1_dc0_nodes += storage-04 (R-3); tofu validate Success.
- security-ledger SEC-011 closed; session-ledger rulings + sweep progress; model-a-fallback plan.
