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superseded, intent stands); SEC-010 (br_netfilter + hardened --check);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.

Stage 3 (vr1-dc0) prep batch: D-121..D-124 rulings + substrate/rack wiring, HA overlay, NetBox importers
...
Prepares the VR1 Stage-3 DC substrate so the live steps reduce to review-plan-and-apply.
Authoring + offline validation only -- NO cloud mutation; every tofu apply, NetBox --commit,
and rack install stays operator-gated. Four decisions ruled this batch, all recorded:
- D-121 (ADOPTED): make the decorative single-unit control plane REAL. 14 services scale 1->3
(D-009's mechanical scale-up pulled into VR1); node layout = Option C (3 control + 2 compute +
3 storage/DC, sizing set) after a whole-host resource validation (256 vCPU/1024 GiB/10 TiB);
vault sub-ruling = v-a (MySQL-backed, charm-verify gated). Placement-balance rule for Stage 5.
- D-122 (ADOPTED): VR1 site shape -- nested-per-site containment, dark fiber East-West only,
dedicated per-site L3 ISP uplink, 2-NIC fabric-routed DC edge (LAN=provider-public, WAN=uplink),
per-site MAAS. Edge NIC count baremetal-matched (nodes 6, edge 2).
- D-123 (ADOPTED Model A): DC nodes vcloud-level; site-down = destroy the vr1-dc0-* group; MAAS
region on Office1 + a rack controller per DC (vvr1-dc0).
- D-124 (ADOPTED Scheme A): the Office1-region<->DC-rack management overlay -- a transit link on
the office1<->dc0 mesh leg; rack sizing 4/8192/80.
Code (all validated, NOT applied):
- OpenTofu: new modules/site-wan (NAT /24 uplink, provider-schema-confirmed); main.tf Stage-3
section -- vr1_dc0_wan, the 2-NIC edge, 8 Option C node VMs (for_each), the vvr1-dc0 rack
(two legs, static IPs from new vr1_dc0_rack_* tfvars -- NetBox-assigned, not invented), netem
held, mesh-link network_name output; stale vr1_dc1_planes comment fixed. Step-9 maas-vm-host
deliberately deferred (DOCFIX-179: its maas provider would force every plan to demand creds).
tofu validate Success; opentofu-validate 11/11.
- NetBox: dc-edge-wan-import.py (58/58) + dc-rack-mgmt-import.py (96/96) -- register the DC-edge
/24s + the rack transit/IP, dry-by-default, whole-plan preflight, operator-supplied literals.
- overlays/dc-ha-scaleup.yaml: the D-121 14-service HA scale-up (Stage-5), placement tokens +
rabbitmq min-cluster-size + hacluster cluster_count + re-declared vault-hacluster.
- scripts/site-headend-install.sh: rack-only mode (enrolls a DC rack to Office1's region).
- runbooks/dc-dc-phase2-tofu-dc-substrate.md: fix-forward (D-119 naming, Steps 4-5 REST-API,
D-121/122 folded in, stale gate corrected).
docs/session-ledger.md + dc-dc-deployment-workflow.md reconciled; three changelogs added.
Gauntlet ALL GREEN; repo-lint 0-fail (1 documented legacy WARN).

D-119: region-qualify the VR1 DC namespace -- C3 / gap #19 CLOSED (Stage 3 unblocked)
...
THE BUG: the token `dc0` meant TWO DIFFERENT CLOUDS depending on the file --
VR0's LIVE testcloud in scripts/lib-net.sh, VR1's FIRST DC in the NetBox
importer. One string, two clouds, one of them in production.
THE RULING (operator): the repo adopts the apex's names verbatim.
vr0-dc0 VR0's DC0 the LIVE testcloud (a DIFFERENT region)
vr1-dc0 VR1's FIRST DC GUA 2602:f3e2:f02::/48
vr1-dc1 VR1's SECOND DC GUA 2602:f3e2:f03::/48
Bare dc0/dc1/dc2 are now REJECTED LOUDLY everywhere.
D-119 COMPLETES D-117, it does not reverse it: it executes D-117's own amendment
across the three surfaces D-117 never touched. ZERO NetBox writes -- the apex was
already correct and self-consistent (MEASURED: f02::/48 -> vr1-dc0, f03::/48 ->
vr1-dc1); the REPO was the only surface out of step. Renaming the apex to match
the repo was considered and REJECTED (production IPAM write; VR1 would become the
only 1-indexed region; and vr1-dc1 would mean VR1's FIRST DC while vr0-dc1 means
VR0's SECOND).
THE PRIZE: the importer's DC->site map is now an IDENTITY -- there is no offset
table left to get wrong, and an assert enforces it. The original defect was
precisely a WRONG LOOKUP TABLE. The bug class is deleted, not defended.
TWO REAL BUGS the naming fix ALONE would NOT have closed (found by review sweep):
- BREAK-1: descriptions were built with f"VR1 {dc.upper()} ..." -- under D-119 that
renders "VR1 VR1-DC0 provider-public" on all 36 prefixes. Same class as the
original bug (deriving a label by munging a token), hidden in the description
field where slug-focused review missed it. Now looked up from SITES[name].
- BREAK-2 (the important one): DC_GUA_PREFIX was NEVER cross-checked against --dc.
`--dc vr1-dc0 DC_GUA_PREFIX=<f03>` was ACCEPTED: it writes the SECOND DC's GUA,
carved with the FIRST DC's ULA nibble, scoped to the FIRST DC's site -- a
silently mis-bound datacenter assembled from two disagreeing sources. Identity-
mapping the slug leaves the ADDRESSING free-floating. Now guarded by EXPECTED_GUA.
ALSO: vdc1/vdc2 -> vvr1-dc0/vvr1-dc1 (D-114 amendment). D-114's own DR primitive is
`virsh destroy vdc1`, which read as "destroy VR1 DC1" while MEANING "destroy VR1
DC0". A mislabelled destroy command in a DR drill is not cosmetic. Neither VM is
built, so it is free. voffice1/Office1 KEEP their number (operator ruling).
Env var: DC1_/DC2_V4_SUPERNET -> VR1_DC1_V4_SUPERNET (both old names rejected).
rbd-mirror's --site-name aligned: `--dc vr1-dc0 --site-name dc1` was a re-created
two-namespace collision on one command line.
TESTS: dc-selector 21->30, prefixes-import 40->82 (identity invariant; EXPECTED_GUA
in BOTH mismatch directions; mismatched run writes NOTHING; matching pair still
succeeds; no munged description). GAUNTLET ALL GREEN (57). repo-lint 0 fail.
The old harnesses PINNED THE WRONG MAPPING -- they would have gone green while
enforcing the bug.
THE tofu apply IS NOT DONE -- IT IS GATED. Plan: 11 to add, 0 to change, 11 to
destroy (libvirt object names are ForceNew; moved{} makes the plan reviewable but
cannot suppress a replace). MEASURED SAFE: all 11 are EMPTY -- no guests, no
volumes, Stage 3 hasn't run. Office1's live objects are not in the plan.

D-114: voffice1 is LIVE. cloudinit-vm gains nested virt -- it was silently broken for the model
...
APPLIED, operator-approved: 5 added, 0 changed, 0 destroyed. The running OPNsense edge was NOT
touched (confirmed by plan BEFORE apply -- no in-place update, so no repeat of the 2026-07-13
guest bounce).
THE MODULE WAS SILENTLY BROKEN FOR D-114'S ENTIRE MODEL. modules/cloudinit-vm's libvirt_domain
had NO `cpu` block. With none, libvirt renders a GENERIC EMULATED CPU exposing no `svm` -- and
LXD *virtual machines* are qemu/KVM guests, so NO service VM could ever have been composed into
voffice1. D-114 would have failed at its first step with a confusing "KVM not available" that
pointed nowhere near OpenTofu. Measured proof of the masking: host is an AMD EPYC 9965; a
default-CPU guest was handed an "Opteron_G3".
Fix: `cpu { mode = "host-passthrough" }` always, plus a new `expose_nested_virt` variable with NO
default -- a real per-VM decision. true = pass `svm` through (required for D-114's containment
VMs); false = disable it, matching modules/opnsense-edge. The operator asked whether the edge's
`svm` disable was a leftover of the failed OPNsense deploy: it is NOT. It was tried as a
triple-fault fix on 2026-07-12, did NOT resolve it (the real cause was the memory unit), and was
retained on hardening grounds. A router has no business seeing nested virt. It stays disabled there.
voffice1 as built (MEASURED): Ubuntu 24.04.4 LTS, 16 vCPU / 32 GiB / 600 GiB, single NIC on
office1-local, reports the real EPYC CPU with svm on all 16 cores and /dev/kvm PRESENT, egress to
1.1.1.1 at 4.6ms THROUGH the edge. Cloud-init deliberately MINIMAL (identity + key + guest agent);
MAAS and LXD go in as separate GATED steps rather than buried in a first-boot script that either
silently works or silently does not. The SSH pubkey is read via file(var...) at plan time -- key
material never enters a command line, the repo, or an agent's context; the tfvars holding the path
stays gitignored. network_config matches the NIC by GLOB, not a guessed kernel name (an inferred
value); it came up enp1s0.
TWO GATES CLEARED:
1. KEA HAS SERVED ITS FIRST REAL DHCP LEASE. Standing open item: the daemon was proven, the
SERVICE never was (office1-local had no client). voffice1 -- the first client ever on that LAN
-- took 10.10.0.100, hwaddr 52:54:00:6a:87:e5 (matches its NIC), hostname voffice1, state
active, read back through the D-113(a2) REST API. DHCP now works end to end.
2. D-114's NESTING PROBE PASSES AT L3. Stated honestly: this proves nested KVM is AVAILABLE. The
DEFINITIVE proof is a guest actually booting inside voffice1 -- that lands with the first
composed LXD VM. Not recording L3 as fully proven until then.
FINDING, logged NOT actioned (DC1 is gated behind Office1 per D-114): modules/node-vm has the SAME
missing-cpu-block defect. DC nodes run nova-compute, which needs working KVM -- without the fix
they will come up unable to run a single instance. MUST be fixed before Stage 3.
opentofu-validate PASS, repo-lint 0 fail.

DC-DC Stage 1 (dc-dc-phase0): first real execution + scaffold/tooling fixes
...
First end-to-end run of a DC-DC runbook against real infrastructure (vcloud host,
OpenTofu v1.12.3). Applied 13 libvirt objects (6 DC1 planes, dc1/office1/dc2
pools, office1-local, 3 mesh legs, all MTU 9000); prior VR0 nets torn down (wan
kept as a gap-#17 model); DC2 planes deferred (NetBox supernet), DC2 storage wired.
DOCFIX-178: scripts/prereqs/ idempotent workstation prereq installers + a
Prerequisites section in the runbook + tests/prereqs/ (25/25). Runbooks must
not assume prereq runtimes.
DOCFIX-179: OpenTofu scaffold first validation + apply. Per-module
required_providers (child modules do NOT inherit provider SOURCE -> OpenTofu
inferred nonexistent hashicorp/libvirt); tofu fmt -recursive; provider "maas"
deferred to Stage 3 (kept a sensitive key out of Stage-1 plan/state);
repo-lint now skips the .terraform/ provider cache; .terraform.lock.hcl added.
DOCFIX-180: dc-dc-phase0 runbook as-executed corrections folded in at phase
close (two MTU domains, non-pristine-host handling, Step-9 13-resource plan,
-input=false, Known-Gap resolved).
repo-lint 0 fail; prereqs harness 25/25; repo-lint harness 34/34.

DOCFIX-175/176: OpenTofu state file security + VR1 teardown/rollback runbook
...
Found while reviewing what's missing from the VR1 buildout ahead of
tomorrow's execution.
DOCFIX-175: terraform.tfstate stores sensitive=true variables (like
maas_api_key) in plaintext regardless of the flag, which only redacts
CLI/plan output (verified against HashiCorp's own docs). Added .gitignore
coverage, a "State file handling" section in opentofu/README.md, an inline
caveat on maas_api_key's description, and a "SECURE THE STATE FILE" callout
at Stage 1 Step 10 -- the actual first real tofu apply (an early draft
wrongly assumed Stage 3; corrected after reading the runbooks directly).
DOCFIX-176: new runbooks/dc-dc-teardown-rollback.md for the OpenTofu/
libvirt/MAAS-vm_host layer, which D-061's existing teardown scripts don't
cover (different layer, juju/MAAS-machine). Two paths (scoped -target
teardown or full VR1 destroy), a rollback decision tree favoring
fix-forward over destroy, and explicit mesh-link shared-infrastructure
handling.
Also folded in: a fix to docs/changelog-20260710-ledger-scan-self-inflicted-falsepositive-fix.md
after re-running ledger-scan.sh caught that its own narration (and the
session-ledger mirror) had reintroduced the exact false-positive class
DOCFIX-174 had just fixed.

DOCFIX-147: opentofu/modules/maas-vm-host + modules/netem-link
...
Registers the vcloud host with MAAS as a virsh VM host, and applies tc netem
WAN-simulation parameters -- the two remaining unbuilt mechanisms from the
OpenTofu scope, researched before drafting per instruction.
maas-vm-host uses canonical/maas's maas_vm_host (register the chassis so
MAAS discovers already-existing VMs), deliberately not maas_vm_host_machine
(composes new VMs itself -- takes cores/memory/disks as inputs). Read both
schemas and cross-checked against D-103's explicit "MAAS does NOT compose
new ones" before picking one.
netem-link uses terraform_data (OpenTofu's own recommended replacement for
null_resource) with an SSH-wrapped local-exec provisioner -- confirmed
local-exec runs on the machine invoking tofu apply (Office1 per D-103), not
the vcloud host where the bridges live, so a bare local command would do
nothing useful.
Neither module instantiated: needs a real MAAS zone/pool, the vcloud host's
SSH target, and real netem parameters, none of which exist yet.

DOCFIX-142: opentofu/ network + storage-pool scaffold (VR1 IaC, gap #2)
...
First OpenTofu content in the repo. Network/pool layer only: modules/dc-planes
(the six per-DC planes, D-052/D-100), modules/mesh-link (the D-100 dark-fiber
triangle), modules/dc-storage-pool, wired for DC1 (inherits DC0's CIDRs per
D-101) and Office1. DC2 deliberately not wired -- its CIDRs aren't assigned
yet (D-101 open sub-item).
Provider schema (dmacvicar/libvirt v0.9.8) verified against its actual current
docs this session, not memory -- it has diverged materially from older common
examples (network isolation is a nested forward.mode, not top-level mode;
libvirt_domain restructured to ~40 args mirroring raw libvirt XML). Node-VM/
volume resources, OPNsense config, and tc netem application are deliberately
deferred: that schema is too large/unfamiliar to author safely without a real
`tofu providers schema` pass on a connected machine -- see opentofu/README.md
for the full account and the concrete next step.
Added scripts/opentofu-validate.sh (fmt/init/validate wrapper) + a harness
testing what's actually exercisable without a tofu binary (none is available
anywhere this repo has been worked in this session -- logged, not hidden).
Extended repo_lint.py's L1 check to cover .tf files (uncovered before since
none existed). repo-lint 0 fail / 1 documented warn; both harnesses green.
Workflow doc + its companion visual tracker updated to match.
