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.
