CORRECTION (GA-R1/C2): D-125 rack-bridge follow-up was CONFOUNDED, not evidence ...

The rack has no default route (transit-only netplan; WAN bridge IP-less),
so 172.30.2.51-sourced traffic to 1.1.1.1 fails in the rack's own routing
table before the NAT is consulted. Its ICMP/TCP failures say nothing about
virbr4; the only clean signal is the guest's ICMP failure, and a guest TCP
datapoint is still missing. Measurement request widened accordingly: FULL
nft AND iptables-save dumps (backend unmeasured), diffing virbr4 vs
virbr11 across BOTH rule families -- POSTROUTING masquerade (subnet-keyed)
and FORWARD accept (interface-keyed, which a subnet grep would miss).
Fix-forward pre-staged: net-destroy/net-start reinstalls libvirt's rules.

D-125 egress gate executed (throwaway VM, as ruled): bridge-in PROVEN, upstream NAT egress fails -- gate OPEN pending one sudo measurement ...

Run 1 was a test artifact (probe used DHCP; uplink /24 has no <dhcp> by
design -- DOCFIX queued for the gate wording). Run 2 static: gateway
ping 3/3 across the nested bridge = the D-125 property PASSES; 1.1.1.1
fails for ICMP and TCP alike. Controls pass and net-dumpxml shows the
working/failing NATs are substantively identical, so the suspect is
vcloud's live virbr4 rules, not the design -- double-NAT fallback
deliberately NOT invoked. Probe guest + temp addresses removed.
CURRENT-STATE updated in this commit (GA-R1/C1).

DC edge bootstrap: D-112(c) console chain complete + API key minted; D-113(a2) PROVEN on 26.7 ...

Key-only root SSH to vr1-dc0-opnsense; GET core/firmware/status 200
(CORE_ABI 26.7) -- first 26.7 revalidation datapoint for the API path.
Five measured console-bootstrap findings recorded (base64 chunking for
serial wrap; tcsh quoting; measured shell_safe include; local_user_set
required to materialize authorized_keys). Rack legs 10.12.4.2/10.12.8.2
added interim; script support queued as a finding.

Deploy step C COMPLETE: inner apply 28/28 from voffice1, converged zero diff; 9 nodes + 26.7 edge RUNNING at depth-4; three first-real-apply fixes ...

voffice1 = Plane-2 executor (tofu 1.12.4, repo @29cf7bf, dc0 key,
keyscan'd known_hosts). Fixed forward, measured at first real use:
provider keyfile/sshauth URI params; wan-bridge illegal <mtu> in
bridge mode; base image uploads from the EXECUTING host (copied to
voffice1, description corrected); staging-dir literal created on
rack. Captures: inner-{plan,apply,converge}-20260720-stepC*.
Edge serial log at FreeBSD login prompt (26.7 D-112 first datapoint).

Deploy step B COMPLETE: rack bootstrapped + enrolled, SEC-010 CLOSED both ends (operator-ruled), OPNsense 26.7 base staged (operator-ruled); ledger-scan fail-open hardening ...

Bootstrap runs 1+2 (stale-lists 404 fixed by proxied apt update):
maas 3.7/stable, rack enrolled, libvirt+nested KVM, SEC-010 loaded
+ persistent on enp1s0; final --check EXIT 0 ALL items
(docs/audit/stepB-check-20260720-final.txt). voffice1-side SEC-010
pin applied per the row's follow-on clause. 26.7 nano prepped on the
rack (measured leaseweb mirror via region proxy); inner-root base
default -> 26.7. ledger-scan: FAIL-OPEN no longer counts as OPEN
(harness 45/45). CURRENT-STATE position/G10/G14 + section-5 updated
in this commit (GA-R1/C1). Open SEC count 8 -> 7.

Step B transit reach ESTABLISHED: voffice1 .1/30 applied (Kea re-key incident fixed); vvr1-dc0 netplan set-name root cause fixed; zero-diff converged ...

voffice1 transit NIC applied 1/1/1 exact; MAC-regen broke the Kea
reservation (measured .108) -- re-keyed via edge API, .20 restored.
vvr1-dc0 both-NICs-silent root cause: netplan match.name+set-name
(one-boot rename lag, measured offline via libguestfs); fix drops
set-name, keeps measured enp1s0/enp2s0, instance-id bump, seed
-replace 2/0/2 exact. Verified: ssh -J voffice1 w/ dc0 key,
rack->region 0% loss. Outer plan ZERO DIFF converged.
