# Session-ledger rotated bodies (GA-R4 rule-6 one-time rotation, 2026-07-19)

Rotated verbatim from docs/session-ledger.md during sweep Batch 4. These are
the pre-rotation body sections (Live state 2026-07-13; OPEN WORK VR1 + VR0;
NetBox write-path bugs; PINNED rulings; standing lessons + state facts --
ROUTED to durable homes, see the Batch-4 changelog; project-completion;
NetBox import narrative). Status claims herein are HISTORY -- the status
authority is docs/CURRENT-STATE.md. Byte content unmodified below this line.

## Live state (measured 2026-07-13; nothing is mid-flight)

- **VR1 / Office1 edge `office1-opnsense` is UP and healthy.** LAN 10.10.0.1/24, WAN 172.30.1.2
  (gw 172.30.1.1). Routing + automatic NAT, egress 0.0% loss, 8 LAN pass rules in pf, serial
  console + getty alive, and `kea-dhcp4` serving DHCP on udp/67 (subnet 10.10.0.0/24, pool
  .100-.199). **DHCP is API-MANAGED (D-113(a2)).**
- **OpenTofu repo/state back IN SYNC -- D-119 rename APPLIED (2026-07-14, operator-gated).**
  `tofu apply`: **11 added, 0 changed, 11 destroyed**; `tofu plan` now reports "No changes". Verified
  on the host: six `vr1-dc0-*` networks, three `mesh-vr1-*` links, `vr1-dc0-pool`/`vr1-dc1-pool`; ZERO
  old `dc1-*`/`dc2-*`/`mesh-dc*` names remain. Pre-apply LIVE re-check confirmed all 11 objects empty
  (0 leases, 0 volumes, no domain attached). Office1 (`office1-local`/`office1-wan`/`wan`/edge/
  `voffice1`) was NOT in the plan and is untouched -- edge + voffice1 still reachable post-apply.
  tofu v1.12.3; tree validates (10/10 modules); lock committed.
- **VR0 / DC0 testcloud:** fleet fully current (juju 3.6.25, 91 agents); D-011 CLOSED except
  item 6 (manual unseal, blocked on SEC-003). devteam is a live tenant running their own
  cluster. No beta cluster, no foil tenant, no orphan trustees (see State facts).
- **STAGE 2 CLOSED AND MERGED (2026-07-15).** All close-out gates C1..C5 met; branch
  `dc-dc-stage1-phase0-first-exec` merged to `main` via **PR #1 (`e468d2e`, merge commit)** -- the
  FIRST VR1 feature merge. `main` is now trunk-of-record for VR1 through Stage 2; the merged branch
  was RETIRED (local + remote). **NEXT: Stage 3** (DC0/DC1 substrate, `dc-dc-phase2`->`phase3`) on
  branch **`dc-dc-stage3-phase2-dc-substrate`** (off post-merge `main`); read
  `docs/dc-dc-deployment-workflow.md`'s tooling-gap register FIRST. Now standing: **branch-per-stage +
  merge-at-close** discipline (workflow doc Cross-cutting) -- merging the stage branch is part of every
  stage's definition-of-done. In place for Stage 3: region-qualified `$DC` selectors (D-119) + the
  creds-audit mint-time discipline (SEC-009 / `scripts/creds-audit.sh`).
- (historical) Branch `dc-dc-stage1-phase0-first-exec` was pushed and level with origin (2026-07-14);
  VR1 Stage 1 COMPLETE; Stage 2 was in CLOSE-OUT -- now superseded by the merge above.
- **SESSION CONSOLIDATION (2026-07-14).** Work had fragmented across FOUR concurrent Claude sessions
  on this one clone -- including two long-lived `--permission-mode auto` background agents (idle 14-15h
  but still holding auto-approve rights against the live cloud), and a second interactive session that
  received the SAME "resume last night's work" prompt six minutes before this one and began bootstrapping
  in parallel. All three were terminated and the supervising daemon stopped (it had respawned the agents
  once). **Standing lesson: the daemon ADOPTS AND RESPAWNS background workers -- killing the child is not
  enough; stop the daemon (`claude daemon stop --any`).** The working tree was clean and 3-ahead
  throughout; nothing was lost or clobbered. ONE session is now the rule.
- **Last night's three commits (D-113 amendment + the v6 script) were made by the auto-permission
  background agent and left UNPUSHED and UNDOCUMENTED.** Both closed 2026-07-14: pushed, and
  `docs/changelog-20260714-opnsense-set-interface-v6.md` written.

## OPEN WORK -- VR1 DC-DC (the current mission)

**D-120 ADOPTED + EXECUTED (2026-07-15) -- static-services addressing for the compose /24s.**
Office1's two services were re-IP'd OUT of the MAAS node band into the `.2-.49` static band:
`office1-netbox .201 -> 10.10.1.10`, `office1-tailscale .202 -> 10.10.1.11`. On the wire, no wipe
(NetBox HTTP 200 at .10; tailscale still advertises `10.10.0.0/22`). Band layout ratified: `.2-.49`
static / `.100-.200` dynamic / `.201+` nodes, for every MAAS compose /24; DCs inherit it from day
one. Method finding: MAAS won't edit a Deployed machine's interface (lift = redeploy = WIPE), so the
address is set on the guest (netplan + curtin, over `lxc exec`) and MAAS-model drift is accepted
(reconciles at next teardown/redeploy). Sweep + gauntlet done; `runbooks/dc-dc-office1-service-reip.md`
now records the measured method. **D-120 Step 6 DONE 2026-07-15** -- the /24 child ranges + the two
service IPs are registered in `office1-netbox` (the VR1 IPAM apex) via `netbox/d120-compose-bands.py
--commit` and VERIFIED by the (now-extended) fidelity check -> exit 0. The `ip-ranges`/`ip-addresses`
tooling gap is CLOSED (dumper + checker now cover both classes). NO apex write -- the upstream
write-back stays DEFERRED to end-of-deployment. This closed the last piece of close-out C2. See
`docs/changelog-20260715-d120-load-and-iprange-tooling.md`.


**D-126 RULED + tooling delivered (2026-07-16) -- durable rootless vcloud->service-VM access.**
Operator ruled Option A (SSH local-forward via `systemd --user`, "continue [the] ssh proxyjump [we
already use]") over persisting the L3 route (root + races libvirt-managed virbr2). Reachability
RE-established this session by the documented ad-hoc route (operator ran `sudo ip route replace
10.10.1.0/24 via 10.10.0.20 dev virbr2` in a real terminal; verified HTTP 302 at 10.10.1.10:8000).
Delivered `scripts/site-forward.sh` + `tests/site-forward/run-tests.sh` (38/38), D-126 record,
as-built access-table update. **SHELL layer added same day** (operator: "you're going to need shell in
Office and the DCs") -- `scripts/site-ssh-config.sh` + `tests/site-ssh-config/run-tests.sh` (30/30)
generate a `~/.ssh/config.d/vr1-sites` ProxyJump alias set (`ssh office1-netbox` etc.), the FOUNDATION
the forward rides; DC aliases deferred until measured post-apply. **SHELL LAYER EXERCISED 2026-07-16**:
operator installed with `~/vr1-office1-creds/office1_svc_ed25519` (one-key closed env, per
`creds-manifests/vr1-office1.manifest`); agent proved `ssh voffice1`/`office1-netbox`/`office1-tailscale`/
`office1-opnsense` all return live from this session -- so the agent now HAS durable shell into Office1
(load-bearing assumption confirmed: key read from config `IdentityFile`, no creds path in command, passes
the guard/classifier). The systemd FORWARD layer stays reviewed-but-unexercised (not installed).
**NetBox apex recovery + edge-WAN import (2026-07-17).** Found the IPAM apex DOWN (netbox-docker cleanly
exited ~3h prior, no auto-restart). Brought it up (`docker compose up -d`, HTTP 302) + added
`restart: unless-stopped` to all 5 services (survives the bookend reboot; override backed up on host).
Both blocks COMMITTED (gated, dry-run-verified; token server-side, sandbox-only). Block A: edge /24s
172.30.2.0/24 (vr1-dc0) + 172.30.3.0/24 (vr1-dc1). Block B: operator chose "write the seeder" -> NEW
`netbox/d124-transit-seed.py` + `tests/d124-transit-seed/` (21/21, incl. a cross-file consistency check vs
dc-rack-mgmt) seeds role `transit` + 172.31.0.0/24 unscoped container; then `dc-rack-mgmt-import` placed
172.31.0.0/30 (transit, vr1-dc0) + 10.12.8.2/22 (rack, dns=vvr1-dc0) -- matches the D-124 tfvars. The full
D-124/edge-WAN IPAM is now in the apex. See
`docs/changelog-20260717-netbox-apex-recovery-edge-wan-import.md`.

**GUEST UPDATES + D-127 IaC AUTOSTART done (2026-07-17).** Office1 guests patched via agent sudo INSIDE
them: 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. **D-127 IaC layer DONE** (operator: bake the matrix so DC0/DC1 not missed): `autostart` var added
to cloudinit-vm/opnsense-edge/node-vm, set per matrix (voffice1/office1-opnsense/DC-edge=true;
vvr1-dc0/nodes=FALSE); opentofu T11-T15 pin it; HARD GATE verified (voffice1/office1-opnsense = autostart
in-place, NOT replacement). Outer plan now 5 add / 2 in-place / 6 destroy (collapses to 0-change once the
bookend sets those two autostart live pre-apply). Standup runbook records the LXD boot.autostart step. See
`docs/changelog-20260717-d127-iac-autostart-and-guest-updates.md`. STILL bookend: vcloud + opnsense patch/reboot.

**vcloud OS-UPDATE + REBOOT window (2026-07-16) -- IN FLIGHT; D-127 autostart policy recorded.**
Operator patching the vcloud host during the open restart window (only Office1 VMs live, before the DC0
build). D-127 RULED: voffice1 autostarts; office1-opnsense autostarts AFTER one verified post-fix cold boot
(DOCFIX-188 mem-unit fix); vvr1-dc0/dc1 containment stay MANUAL. **A host reboot ENDS the running agent
session** -- so this is recorded before it. **POST-REBOOT TODO (next session):** (1) `virsh start voffice1`
+ `virsh start office1-opnsense`, WATCH the edge cold-boot clean (live-boot verification); (2) verify `ssh
voffice1` / `ssh office1-netbox` answer (D-126 ProxyJump; the direct L3 route to 10.10.1.10 is already gone
-- use SSH); (3) THEN `virsh autostart voffice1` + `virsh autostart office1-opnsense` (operator sequencing:
autostart only AFTER clean-startup confirmed); (4) optionally set `boot.autostart` on the LXD service VMs
inside voffice1. Then resume DC0 readiness (`docs/dc0-deploy-readiness.md`).

**UPDATE 2026-07-17 (session-scoped health sweep + edge cold boot) -- the "bookend" is PARTIALLY done,
NOT the way the TODO above assumed.** Measured this session: **the vcloud HOST never rebooted** (uptime
8d 18h, boot 2026-07-08) -- so the host-reboot that "ENDS the running agent session" has not happened.
What DID reboot was the guests: **voffice1** (07-16 20:56, kernel 6.8.0-136) and **office1-tailscale**
(07-17 07:25, kernel 6.8.0-136), both healthy. The **office1-opnsense edge was cold-booted THIS session**
(graceful ACPI `virsh shutdown` -> confirmed `shut off` -> `virsh start`) and VERIFIED clean: up-from-0,
physmem 2.0 GiB (DOCFIX-188 fix live, not 2 MiB), pf Enabled/80 rules, `kea-dhcp4` up, both NICs up, LAN
gw + egress 0% loss, netbox 302 + tailscale reachable behind it. That satisfies the D-127 verified-cold-boot
gate, so **`virsh autostart office1-opnsense` is now ENABLED**. **`voffice1` autostart ALSO ENABLED this
session** -- so BOTH foundational VMs now autostart per D-127 (POST-REBOOT TODO item 3 DONE; `vvr1-dc0/dc1`
stay MANUAL and do not exist yet). **LXD service-VM autostart VERIFIED (2026-07-17):** the two LXD VMs
inside voffice1 -- `office1-netbox` (10.10.1.10) + `office1-tailscale` (10.10.1.11) -- both already carry
`boot.autostart=true` (MEASURED via `sudo lxc config get`; confirms the D-127 guest-update note, no change
made). So the autostart chain is now proven END TO END: vcloud->`voffice1`/`office1-opnsense` via `virsh
autostart`; `voffice1`->netbox/tailscale via LXD `boot.autostart` -- a vcloud host reboot self-recovers the
whole Office1 stack with no manual `virsh start`/`lxc start`. **STILL PENDING:** (a) the vcloud HOST patch+reboot -- kernel **6.8.0-136
is pending in apt but NOT installed** (running -134, newest installed -134, no reboot-required flag), so a
bare host reboot gains nothing: the real step is `sudo apt update && sudo apt full-upgrade` (lands -136 + ~9
security pkgs) THEN reboot; (b) office1-opnsense itself is still on 14.3-RELEASE-p16 (guest OS not patched,
only cold-booted).

**BOOKEND ITEM (a) CLOSED 2026-07-18 -- MEASURED, and the autostart chain PROVED ITSELF FOR REAL.**
The vcloud host was patched and rebooted between sessions: `uname -r` = **6.8.0-136-generic**, `apt list
--upgradable` EMPTY, no `/var/run/reboot-required`, and `last -x reboot` shows TWO boots on 2026-07-17
(17:59 and 23:38; current uptime 5h39m from 23:38, ending the -134 run of 8d20h). Item (a) is DONE. Item
**(b) STAYS OPEN** -- a host reboot does not patch the edge guest; `office1-opnsense` is still on
14.3-RELEASE-p16. **The D-127 autostart chain is now PROVEN BY A REAL HOST REBOOT, not merely configured:**
after an unattended boot, `virsh list --all` shows `voffice1` + `office1-opnsense` both running with
autostart, and `ssh voffice1` / `office1-netbox` / `office1-tailscale` all answer live (all up ~5h38m,
matching the host boot). `site-baseleg.sh check office1` = **ok leg + ok route** (the D-126 oneshot re-added
the isolated-net leg through the reboot). NetBox apex HTTP **302** at 10.10.1.10:8000; edge LAN gw
10.10.0.1 ping **0% loss**. Zero manual `virsh start` / `lxc start` was needed. Office1 is fully self-recovered.

**STAGE-3 WORKFLOW-DOC BLOCKER IS STALE -- reconciled 2026-07-18 (the ledger was right, the doc is wrong).**
`docs/dc-dc-deployment-workflow.md`'s Stage 3 section still reads "**Blocking to EXECUTE:** the HELD NetBox
addressing -- D-124's rack transit/30 + rack metal-admin IP". MEASURED against the live apex
(read-only API GET, token sourced in-shell and never printed): all three objects are PRESENT --
`172.31.0.0/30` (role Transit, scope **VR1 DC0**), the `172.31.0.0/24` unscoped Transit container, and
`10.12.8.2/22`. This matches the 2026-07-17 apex-recovery entry above. The NetBox addressing is NOT a
blocker; the workflow doc's Stage-3 "Blocking to EXECUTE" line needs a DOCFIX (next-free 196).

**!! DC0 OUTER APPLY IS BLOCKED ON NEW DRIFT -- do NOT apply. See
`docs/finding-20260718-voffice1-cloudinit-seed-replace.md`.** Post-reboot re-verification of the outer
root (read-only plan, **OpenTofu v1.12.4**) returns **7 add / 2 change / 7 destroy**, NOT the committed
**5 add / 2 in-place / 6 destroy** in `docs/dc0-deploy-readiness.md`. The entire delta is `voffice1`, the
live headend -- NOT DC0 scope: the libvirt provider staged its cloudinit ISO under
`/tmp/terraform-provider-libvirt-cloudinit/`, **the reboot cleared `/tmp`**, so `create.content.url` reads
changed and **forces replacement of `voffice1`'s seed volume -- which is ATTACHED to the RUNNING domain as
`sda`** (`virsh domblklist voffice1`; the real ISO is intact at
`/var/lib/libvirt/vr1/office1/voffice1-cloudinit.iso`). Replacing it risks bouncing the Office1 headend =
NetBox apex + tailscale + the D-128 Plane-2 execution origin + the D-126 ProxyJump path. This is provider-
state drift, not a config change (the volume-replace CONSEQUENCE on a running domain is **UNVERIFIED** --
do not assert it bounces the guest; trap 1e is about domains, not volumes).
**THE DOMINANT RISK IS THE 2 "in-place" CHANGES, NOT THE VOLUME.** They did NOT collapse to 0 as the D-127
changelog predicted -- both `voffice1` AND `office1-opnsense` plan as `+ autostart = true`, because `virsh
autostart` was set out-of-band and the provider does not refresh it into state. **The bounce is CONFIRMED
FROM PRIMARY SOURCE** (v0.9.8 `internal/provider/domain_resource.go`, fetched + read directly): `Update`'s
only no-bounce path (L1090) requires `domainConfigUnchanged && runningChanged && autostartUnchanged`, and an
autostart-only diff has `runningChanged`=FALSE, so it falls through to **`stopDomainIfRunning`** ->
undefine -> DefineXML -> SetAutostart. ALSO CONFIRMED (L938): Read only reads `autostart` back
`if isImport || state.Autostart` is non-null -- ours is NULL, so **`-refresh-only` can never populate it**
(matches the empirical `grep -c autostart` = 0 on both domains). NOTE: an earlier draft cited
`platform-traps.md` 1e as the warrant here; 1e was measured on a *memory* change and does NOT transfer to
an autostart-only diff -- the conclusion held but the reasoning was wrong, now replaced by the source above.
1e's operational rule still stands independently: `0 to change` on the domains is the ONLY assurance a guest
will not bounce. So the unscoped apply
would take Office1's headend AND edge down -- to write a value that is ALREADY LIVE on both. An earlier
draft of this finding called these changes "harmless"; that was WRONG and is corrected here and in the
finding doc. Pinned provider = dmacvicar/libvirt **0.9.8**.
Options (a)-(d) are in the finding. **DC0 IS NOT BLOCKED on the unresolved provider question:** the intended
DC0 work (create `vvr1-dc0` + uplink, destroy 6 empty planes) touches NO running guest, so **(a) `-target`
the DC0 addresses** sidesteps both risks and is recommended for the immediate apply, with **(b) reconcile
state first** (`-refresh-only` / re-stage) as the deliberate follow-up to get back to `0 to change`.
**(d) standing hardening:** keep the provider's cloudinit staging OFF `/tmp` so a reboot can never again
force-replace a live VM's seed. **BLAST RADIUS CORRECTED (MEASURED 2026-07-18):** an earlier draft of this
entry claimed this hits "all 9 DC0 node VMs and every DC containment VM" -- **WRONG, retracted.**
`libvirt_cloudinit_disk` appears in exactly ONE module (`modules/cloudinit-vm`), instantiated exactly TWICE
(`main.tf:181` voffice1, `main.tf:361` vvr1_dc0). The 9 nodes use `modules/node-vm` = blank-disk PXE, NO
cloud-init; the edges use REST config (D-113(a2)). Real exposure = **voffice1 + vvr1-dc0 (+vvr1-dc1) = 3**.
Also: on a CLEAN deploy the disk+volume are created in the same apply so there is NO diff -- this only
surfaces on a plan taken after a host reboot, so it does not break a post-teardown redeploy, only ops.
**Mechanism correction:** there is **NO provider knob** for this (VERIFIED via `tofu providers schema
-json` -- provider block exposes `uri` ONLY; `libvirt_cloudinit_disk` has no staging attr); the lever is
almost certainly **`$TMPDIR`** for the tofu process (Go `os.TempDir()`), UNVERIFIED by observation --
confirm before writing it up. Warrants **D-130** (next-free confirmed 2026-07-18).
**Before ANY apply:** re-run the readiness doc's C1 pre-apply checks THIS session, incl. re-confirming the
6 `vr1-dc0` planes are still empty (0 leases / 0 attached) -- that evidence is from a prior session, and
this finding is itself proof that committed pre-apply evidence goes stale across a reboot.

**Version drift to log:** OpenTofu on the jumphost is now **v1.12.4**; `README.md:41` and the readiness
evidence say **v1.12.3**. Presumed to have arrived with the host patch (not verified). All committed
plan/validate evidence predates it.

**SESSION CLOSE 2026-07-18 (bookend). Full record: `docs/finding-20260718-voffice1-cloudinit-seed-replace.md` (committed 43b29d7).**
ESTABLISHED: (1) An autostart-ONLY diff **bounces the guest** -- VERIFIED FROM PRIMARY SOURCE (libvirt
v0.9.8 `internal/provider/domain_resource.go` L1090/L1107): the sole no-bounce path needs
`domainConfigUnchanged && runningChanged && autostartUnchanged`, and runningChanged=FALSE here, so it falls
through to `stopDomainIfRunning` -> undefine -> redefine. (2) `-refresh-only` can NEVER fix it -- Read is
self-gated at L938 (`isImport || state.Autostart` non-null); ours is NULL. (3) The seed force-replace is
STRUCTURAL: the reboot cleared `/tmp`, where the provider stages cloudinit ISOs, so the url changes every
plan. (4) Blast radius CORRECTED to **3 VMs** (voffice1, vvr1-dc0, +vvr1-dc1) -- NOT the 9 nodes
(`node-vm` = blank-disk PXE, no cloud-init); an earlier claim of mine, retracted.
OPEN: **D-130 mechanism ruling** (`ignore_changes` vs `$TMPDIR` -- operator's call, unruled); **verification
7** (what 0.9.8 does replacing a volume attached to a RUNNING domain -- deliberately unasserted);
**verification 8** (that the chosen D-130 mechanism actually suppresses a force-replacement diff);
**doc-integrity list** (D-127 changelog's false "collapse to 0" + "no forces-replacement", readiness-doc
5/0/6-vs-5/2/6, DOCFIX-196 stale Stage-3 NetBox blocker, README tofu 1.12.3->1.12.4, phase-2 runbook).
Gate before any apply: plan must read EXACTLY 5 add / 0 change / 6 destroy. Nothing applied this session.
**SUPERSEDED: this session is closed out by a grounding audit charter arriving via git -- read that first.**

**DC0 DEPLOY READINESS -- PREP COMPLETE 2026-07-17 (deploy-ready). See `docs/dc0-deploy-readiness.md`.**
Final gate re-checked clean (validate, tfvars, creds-audit vr1-dc0 CLEAN, gauntlet 65, lint 0-fail).
Remaining is NOT prep: the bookend restart (vcloud + voffice1 + opnsense patch/reboot together -- voffice1
is load-bearing like vcloud) + fresh-session (re-verify plan post-reboot + logged shell + gated outer
apply). Decoupled hygiene (NetBox import; Stage-3 record sweep) is OPTIONAL, does not gate the deploy.
Stage-3 Phase-2 DC0 is EXECUTABLE (D-121..125 ADOPTED, R-1/R-2/R-3 ruled, tfvars in, opentofu-validate
clean). Outer-root `tofu plan` RUN + VERIFIED SAFE: 5 add (`vvr1-dc0` 416GiB/108vcpu + D-125 uplink) /
0 change / 6 destroy (the six EMPTY vr1-dc0 planes relocating to the inner root -- verified 0 leases/0
attached). RAM gate: 980 GiB avail >= 416. **Nothing applied.** Next = the gated outer `tofu apply`.
Pre-apply per-env-key DECISION now RULED + IMPLEMENTED (operator 2026-07-16, option a): `vvr1-dc0`
gets its OWN key -- minted `~/vr1-dc0-creds/vr1-dc0_svc_ed25519` (creds-audit CLEAN), added
`vr1_dc0_ssh_pubkey_path` var, `vvr1-dc0` cloud-init reads it (voffice1 keeps office1's key), tfvar set;
re-plan UNCHANGED (5/0/6). netem RULED = placeholder for the rehearsal. Full remaining-prep checklist +
fresh-session bootstrap + gated A-E sequence in `docs/dc0-deploy-readiness.md` (the entry point). Inner
apply must use the dc0 private key (wire post-outer-apply). Gauntlet ALL GREEN (65). Nothing applied.

Original build note: this session had NO ssh key to voffice1
(none in `~/.ssh`, no agent; key is operator-held in `~/vr1-office1-creds/`, correctly un-enumerable),
so the operator supplies `--key` and runs `install` + first-connect + the one-time
`loginctl enable-linger`. Site table seeded office1-netbox only; DC rows DEFERRED (IPs not measured).
Advisor-conferred (untangle two problems): this does NOT gate `tofu plan` -- the tree has no netbox
provider/data source, so the four operator-ruled `vr1_dc0_rack_*` tfvars alone unblock plan; the
NetBox `--commit` stays a decoupled, operator-run, token-on-netbox-host step. See
`docs/changelog-20260716-d126-durable-forward.md`.


**STAGE-3 ADVERSARIAL REVIEW (2026-07-16; advisor + 4-charter debate + Layer-1 gate).**
Full pre-deployment adversarial review of the `a48a60f` batch (D-121..D-124 + substrate/rack/HA
overlay). READ-ONLY; nothing applied/committed/pushed. Deliverable: `docs/stage3-adversarial-review-
20260716.md` (present-only, NOT committed); immutable base patch `docs/stage3-review-base.patch`;
surface frozen at WIP commit `87a7a8a` (local-only). **VERDICT: NO-GO for `tofu apply`** on
hard-gate grounds (substrate design is sound). BLOCKING headline: **2 decisions rest on
inferred/agent-authored rulings** -- D-121 vault-`(v-a)` (no operator utterance; Status `:3264`
contradicts body `:3346`; ENCODED in `overlays/dc-ha-scaleup.yaml:67-80` reversing BUNDLEFIX-002)
AND D-123 Model A ("Do it all now" is not an A/B answer; runbook `:507` already marks D-123
PROPOSED). Both demote to PROPOSED; region+rack/Option C/D-124 stand. Pre-apply gate list (all
operator-gated, for a post-acceptance sweep): (1) re-rule vault + Model A; (2) ship the SEC-010
`ip_forward=0`+firewall ARTIFACT + a mechanical gate (currently a ledger promise); (3) assign the
rack transit/30 + rack IP in office1-netbox, feed the 4 tfvars (tofu plan BLOCKED without them),

**OPERATOR RULINGS on the review (step-by-step, 2026-07-16; NOT yet swept into design-decisions.md
-- these drive the gated fix-sweep):**
- **[R-1] D-123 node containment = MODEL B (operator ruling 2026-07-16, explicit AskUserQuestion
  "Proceed with B, accept all").** Nodes nest INSIDE `vvr1-dc0`; site-down = single
  `virsh destroy vvr1-dc0` (restores the operator's original D-122 intent; the inferred Model A is
  overturned). **Accepted cascade (operator-confirmed after being shown the consequences):**
  (a) supersede ADOPTED **D-103** (OpenTofu-creates-nodes-at-vcloud + MAAS-discovers seam) and
  **D-114** (containment scoped to headend + non-stack LXD machines only, NOT the OpenStack nodes);
  (b) **D-124 rack sizing (4/8192/80) VOID** -- `vvr1-dc0` must contain one DC's full node fleet
  (~360 GiB node RAM + overhead) and set `expose_nested_virt = true`; (c) **depth-4 nested virt
  accepted** as a rehearsal cost (vcloud->vvr1-dc0->compute->nova guest = 3x nested KVM; VR0 proved
  2; Phase-5 workload-boot risk flagged + accepted). Substrate reshape: `node-vm` + `maas-vm-host` +
  6 planes + `vr1-dc0-wan` retarget from vcloud libvirt to `vvr1-dc0`'s inner libvirt. STAGED for
  the sweep; nothing edited/applied yet.
- **[R-2] D-121 vault-HA backend = RAFT integrated storage (operator ruling 2026-07-16, explicit
  AskUserQuestion "Raft integrated storage").** Overturns the agent-authored v-a (MySQL-backed).
  Consequences: DROP the `vault:shared-db -> vault-mysql-router -> mysql-innodb-cluster` storage
  relation; vault uses its own integrated raft (per-unit persistent storage needed); keep the
  `vault-hacluster` VIP. Still 3x manual unseal (SEC-003). **HARD FEASIBILITY GATE -- UNVERIFIED,
  not assumed (cardinal-sin discipline):** must confirm the Charmed `vault` charm (1.8/stable)
  exposes an integrated-raft storage backend before this ruling is actionable. If the charm does not
  support raft, the ruling is moot and returns to the operator (v-a MySQL vs another path). STAGED;
  nothing edited/applied.
  - **[R-2 FEASIBILITY GATE FAILED -- verified 2026-07-16.]** `bundle.yaml:133-138` (D-068 /
    BUNDLEFIX-010): integrated-**Raft storage is a 1.16-charm property**, and the 1.16 vault charm is
    RULED INCOMPATIBLE with this reactive Caracal cloud (certs V0->V1, no upgrade path, **broken with
    Charmed Ceph**). The deployable charm is **1.8/stable** = MySQL/etcd storage, **no Raft**. So the
    operator's Raft ruling is **INFEASIBLE for VR1** without the ruled-out 1.16 charm. Raft is the
    correct *Roosevelt/D-068* target (get vault off 1.8.8-EOL), NOT a VR1 choice. **R-2 RETURNED to
    the operator:** realistic VR1 options = v-a (MySQL, rec) or v-b (etcd, deprecated).
  - **[R-2 FINAL = v-a MySQL-backed (operator ruling 2026-07-16, "v-a: MySQL-backed").]** Vault stays
    on the 3-unit mysql-innodb-cluster (via vault-mysql-router), scale to 3, re-add
    `vault:ha <-> vault-hacluster`. **NO CODE DELTA** -- the committed `overlays/dc-ha-scaleup.yaml`
    already encodes v-a; only the D-121 RECORD needs fixing (attribute to the operator's 2026-07-16
    ruling; reconcile the body's stale "Operator sub-ruling needed"). Charm-verify gate stands (confirm
    vault 1.8/stable does HA leader-election on MySQL at deploy). Raft parked as the D-068/Roosevelt
    target. 3x manual unseal (SEC-003) stands.
- **[R-3] Option C storage resilience = 4 STORAGE NODES/DC (operator ruling 2026-07-16, "Add a 4th
  storage node/DC").** Node layout now **3 control + 2 compute + 4 storage = 9/DC** (18 total, was 16);
  `ceph-osd` = 4 units/DC. Restores Ceph rebuild headroom (lose 1 OSD host -> 3 distinct replicas still
  placeable -> self-heals). Consequences: (a) whole-host RAM ~838 GiB/1024 (81%, hand-estimate -- FITS
  but tighter; the ABSENT `optc-calc.py` must be rebuilt + re-run for the 3+2+4 shape AND Model B
  nesting overhead -- R3-F06 now doubly required); (b) under Model B, `vvr1-dc0` holds ~384 GiB node
  RAM + overhead (~404 GiB VM); (c) Ceph disk re-checked for 4x500Gi/DC = PASS, 5.31 TiB margin;
  (d) `main.tf local.vr1_dc0_nodes` adds `storage-04`, D-121 layout table + sizing updated.
- **[R-4] SEC-011 CLOSED (operator ruling 2026-07-16, "Keep uniform 6-NIC").** A2's Roosevelt-delta
  refutation accepted: uniform 6-NIC matches baremetal VLAN-trunking (all planes trunked to every
  node); isolated-L2 planes = nil reachability in the sim. **NO CODE CHANGE** (keep uniform
  `local.vr1_dc0_node_nics`); amend the SEC-011 ledger row to CLOSED / accepted-non-issue.

**SWEEP PROGRESS (2026-07-16):**
- **Phase A DONE** -- record amendments (`design-decisions.md` D-103/D-107/D-114/D-115/D-121/D-122/D-123/
  D-124 + `security-ledger.md` SEC-011 close). Decision record now internally coherent; D-115
  ledger-scan false-positive fixed. `docs/changelog-20260716-review-sweep-phaseAB.md`.
- **Phase B DONE** -- `scripts/dc-dc-whole-host-budget.py` + `tests/dc-dc-whole-host-budget/` (13/13)
  replace the lost `optc-calc.py` (R3-F06). Re-validation: Model B 3+2+4 = 838 GiB/1024 FIT (186
  headroom). Gauntlet 63 ALL GREEN.
- **Phase C IN PROGRESS** -- Model B OpenTofu reshape. Design cross-checked by a 3-charter agent
  workflow (compatibility/best-practice/structure): mechanism = **TWO-ROOT / TWO-STATE split** (forced
  by the provider-cannot-depend-on-same-apply-resource invariant; -target + provider-with-unknown-values
  are anti-patterns). OUTER root (main.tf, vcloud) = vvr1-dc0 resized + transit + office1; INNER root
  (NEW `opentofu/vr1-dc0-substrate/`, own state) = 6 planes + wan + edge + inner pool + 9 nodes, modules
  reused VERBATIM. BOOTSTRAP GATE between (extend site-headend-install.sh: nested libvirtd/pool/nested=1/
  base image). Verdict GO-WITH-MITIGATION on depth-4. **[R-5] inner transport = REMOTE qemu+ssh from
  Office1 (operator ruling 2026-07-16)** -- tofu on Office1, dials vvr1-dc0 over the D-124 transit; both
  states on Office1. **vvr1-dc0 sizing DERIVED (not invented) = 108 vCPU / 416 GiB / ~3000 GiB**
  (104 node vCPU + 4 oh; 384 node GiB + 32 oh; 2850 inner pool + OS), whole-host 870/1024 (85%) FIT.
  DONE so far: storage-04 (R-3), fallback re-cut R-3-compliant (114d392); **C1 OUTER root** (main.tf:
  vvr1_dc0 resized via var.vvr1_dc0_* [108/425984/3221225472000, derived], expose_nested_virt=true,
  single transit leg; removed planes/wan/edge/node blocks + the dangling moved block; tofu validate
  Success); **C2 INNER root** `opentofu/vr1-dc0-substrate/` (versions/variables/main.tf: qemu+ssh
  provider + inner pool + 6 planes + wan + edge + 9 node-vm, modules reused verbatim; init+validate
  Success). Both roots validate; repo-lint 0-fail. Cross-check agent running on the two-root impl.
  **C3 DONE + REVIEWED** -- `site-headend-install.sh` `--host-nodes` (rack-only) node-host mode: installs
  qemu-kvm+libvirt, persists+verifies kvm nested=1, adds ssh user to libvirt group, inner pool dir +
  AppArmor grant, verifies/instructs the OPNsense base (delegated to opnsense-prep-image.sh). Harness
  32->45/45. Review-after-step (per operator discipline): gauntlet ALL GREEN (63), repo-lint 0-fail,
  ASCII/CR clean, grounding OK (implements the C3 bootstrap the inner-root header names), drift sweep
  clean (record/docs/code all reference "node-host mode" consistently). `docs/changelog-20260716-review-
  sweep-phaseC.md`.
  **PHASE D + REMAINDER DONE + REVIEWED (2026-07-16):**
  - **SEC-010 (Phase D)** -- artifact COMMITTED in the node-host bootstrap: a FORWARD-drop across the
    transit leg (NOT a global ip_forward=0 -- the inner vr1-dc0-wan NAT forces ip_forward=1), written to
    /etc/nftables-sec010.nft + boot-persistent sec010-fw.service; `--host-nodes --check` is the mechanical
    pre-apply gate. Harness 45->48/48. SEC-010 ledger row reconciled to the code. Stays OPEN until
    applied+verified on vvr1-dc0.
  - **maas-vm-host** -- header updated for Model B (register vvr1-dc0's INNER/local virsh to the Office1
    region; no cross-fiber dial). Still DEFERRED (DOCFIX-179; not instantiated).
  - **C5 runbook reorg** -- `dc-dc-phase2-tofu-dc-substrate.md` gains the "D-123 MODEL B RESHAPE" section:
    outer apply -> bootstrap gate (site-headend --host-nodes) -> inner apply -> maas-register; Step 6's
    "8 nodes" superseded by R-3's 9.
  - **model-a-fallback-plan.md** synced (~416 GiB; inner-root + node-host mode added to the B->A delta +
    revert procedure).
  Review-after-each-step applied throughout (harness/validate/lint/ASCII/drift per step). All Phase C+D
  items COMPLETE. NOTHING applied/committed since 114d392; Phase C/D edits present-only in the working
  tree. REMAINING (operator-gated, deploy-time): the actual outer/bootstrap/inner APPLIES + rack-IP
  assignment (Phase E, L1-07) + the depth-4 nested-virt L4 boot gate. 
  - **Model B cross-check (agent) = FAITHFUL, no BLOCKING**; fixes applied: 32-GiB-overhead RATIFIED in
  the record (870/154, vvr1-dc0 416 GiB), false metal-admin-IP comment corrected, SEC-010 updated for the
  single-leg-outer/bridges-6-inner-planes reality. **OBS-3: design gap RESOLVED by D-125; egress efficacy
  is a deploy-time gate (see the C+D-commit entry below).** Transit IP is duplicated across roots
  (`vr1_dc0_rack_transit_ip` outer / `vvr1_dc0_transit_ip` inner) -- keep equal in tfvars.

- **Stage-3 sweep C+D COMMITTED as `5175365`** (operator "commit but don't push"; NOT pushed). The
  adversarial re-run then confirmed **OBS-3 material** once the operator ruled **"DC0 and DC1 have their
  own ISP connections"**, resolved by **D-125 (bridge-in, single-NAT)**:
  - Model B nesting had severed per-DC ISP egress: `modules/site-wan` makes `vr1-dc0-wan` a libvirt NAT
    that egresses via ITS HOST's default route; under Model B that host is `vvr1-dc0` (transit-only,
    East-West, SEC-010 FORWARD-dropped) -> dead. Fix: vcloud ISP NAT `vr1-dc0-uplink` + an IP-less uplink
    NIC + netplan bridge `br-vr1-dc0-wan` on `vvr1-dc0`; inner `vr1-dc0-wan` becomes a BRIDGE (new
    `modules/wan-bridge`) so OPNsense WAN rides to the single vcloud NAT. **Authored present-only; both
    roots validate; NOT closed -- the L2-NAT-of-foreign-MAC path is a DEPLOY-TIME gate (bridge-in
    equivalent of the L4 boot gate), fallback = double-NAT.** See D-125 + platform-traps 1g.
  - **No new HELD gate (CORRECTED 2026-07-16):** the vcloud ISP /24 is the SAME `172.30.2.0/24` D-115
    already ruled for vr1-dc0 (bridge-in is single-NAT; IPAM identity unchanged from Model A), inlined as
    a ruled literal in `module "vr1_dc0_uplink"` -- NOT a NetBox-assigned tfvar. OPNsense WAN stays `.2`;
    no re-address. D-125 adds NO NetBox object. (An earlier draft's `vr1_dc0_uplink_cidr` HELD var +
    re-address were removed -- see the correction commit below.)
  - **br_netfilter constraint:** SEC-010 FORWARD-drop stays interface-scoped, NEVER globalized. `--check`
    hardened: fail-open guard now covers the transit-iface existence AND the WAN bridge/uplink enslavement.
  - Harness: `site-headend-install` 49->54; `wan-bridge` covered by opentofu-validate S3. Records: D-125,
    SEC-010, model-a-fallback B->A delta (item 8 + revert), platform-traps 1g.
  - **D-125 COMMITTED `d34ec94` + PUSHED** (operator "commit", then "push"). Branch
    `dc-dc-stage3-phase2-dc-substrate` now carries `114d392` (A+B) + `5175365` (C+D) + `d34ec94` (D-125)
    on origin.

- **Doc drift-reconciliation batch (post-Model-B/D-125), all doc-only, COMMITTED + PUSHED:**
  - `8496c2e` -- `dc-dc-deployment-workflow.md` Stage-3 section reconciled to D-121..125 + Model B
    two-root (Build/Gate/Owns/Authoring-status/rulings-summary); gap-register D-113(a2) OPEN->DONE.
  - `87f9d75` -- `opentofu/README.md`: authoritative STATUS-RECONCILED banner (two roots, added
    `site-wan`/`wan-bridge`, instantiation reality) + neutralized the DELETED, dangerous OPNsense
    config.xml/config-ISO path (D-112/D-113(a2)).
  - `788911c` -- `runbooks/dc-dc-teardown-rollback.md`: Model B two-root teardown banner (site-down =
    one `virsh destroy vvr1-dc0`; inner-then-outer order; maas-vm-host targets inner virsh).
  - Repo-wide drift scan confirmed the deleted-file / old-node-count references elsewhere are all
    immutable CHANGELOGS, decision-record supersession context, or deliberate tombstones
    (`opentofu/templates/README.md`) -- NOT live drift. Deeper prose in the three reconciled docs +
    the Stage-4/5 sections still lag Model B (flagged in-banner as historical), not yet rewritten.

- **D-125 addressing CORRECTED (`e270325`) + tightened (`922dd29`)**, then **D-124 addressing PINNED**
  (operator-ratified 2026-07-16): the vcloud ISP /24 is the ruled `172.30.2.0/24` (not a HELD tfvar);
  the D-124 transit supernet is CARVED as **`172.31.0.0/24`** (dedicated `transit` role, scope vr1-dc0),
  transit /30 `172.31.0.0/30`, rack IP `10.12.8.2`. `dc-rack-mgmt-import.py` `CONTAINER` pinned to
  `172.31.0.0/24`; harness rebased, 96/96. **NetBox `--commit` NOT DONE -- office1-netbox (10.10.1.10) is
  UNREACHABLE from the vcloud jumphost (measured) + the apex token is a secret on that host; the write is
  an on-host operator step** (edge-WAN import, then rack-mgmt import, then fill the 4 `vr1_dc0_rack_*`
  tfvars -> `tofu plan`). Exact commands: `docs/changelog-20260716-d124-addressing-pin.md`. NO apex mutation.
- **Phase D NOT STARTED** -- SEC-010 rack `ip_forward=0` + firewall artifact + mechanical pre-apply gate.
- **Phase E NOT STARTED** -- operator assigns rack transit/30 + rack IP in office1-netbox (apex token),
  fill tfvars -> `tofu plan` renders.
- NOTHING committed/pushed; all sweep artifacts present-only in the working tree.
- **[R-1 fallback preserved]** Model A (the not-chosen D-123 option) captured as a revert artifact per
  operator request: `docs/model-a-fallback-plan.md` (architecture + the B->A delta + revert
  procedure) + git tag **`model-a-fallback`** on `87a7a8a` (local-only). Revert = `git checkout
  model-a-fallback -- opentofu/`. Model A already validates (no re-engineering needed).


**PLANE-SEGREGATION REVIEW of the Stage-3 commit (2026-07-16; advisor + 2 read-only agents).**
Reviewed the committed networking/plane changes (`a48a60f`, NOT applied) for crosstalk / segregation
breaches. **VERDICT: no crosstalk, no active violation -- committed state is SAFE.** All six `vr1-dc0-*`
planes + all three `mesh-*` legs are isolated L2 (measured: `net-dumpxml` shows no forward/ip/nat,
isolation ENFORCED BY CONSTRUCTION in `dc-planes`/`mesh-link`); the edge is 2-NIC so it structurally
cannot reach the 5 non-LAN planes; `vr1-dc0-wan` NAT touches only the edge WAN. metal-admin DC-LOCAL
(D-052/D-100) is **preserved but not ENFORCED** -- it rests on unpinned host defaults. **Two pre-apply
hardening items logged as SEC-010 (rack `ip_forward=0` + transit-leg firewall -- the one real
plane-bridge) and SEC-011 (node role-scoped NIC sets -- least-connectivity).** Say plainly at handoff:
"committed state is safe; two items to close before `tofu apply`." Plus three notes:
- **FUNCTIONAL (fix before apply, not security):** the rack's committed route `to 10.10.0.0/22 via
  <transit_peer>` points at a next-hop with **no VM attached** -- `voffice1` is single-homed
  (`network_names = [office1-local]` only, main.tf:184), NOT on `mesh-vr1-dc0-office1`. As committed,
  apply yields a rack routing to a nonexistent peer, and the Office1<->DC region path is not closed.
  Either wire `voffice1`'s transit leg or gate the rack route until it exists.
- **SEGREGATION CHECK (first boot):** the rack NIC->plane mapping (`enp1s0`->metal-admin,
  `enp2s0`->transit) is assumed PCI-order==name; if swapped, the metal-admin /22 lands on the
  Office1-facing wire. Verify via MAC (`virsh domiflist` x `network_names` order) before trusting
  addressing. This is a segregation check, not cosmetic.
- **DEFERRED (track):** the edge WAN<->provider-public firewall is post-boot REST (opnsense-api),
  not in the commit -- "enforced by absence" covers plane REACHABILITY only, not full edge hardening.
When `voffice1`'s transit leg is later wired it becomes an office1-local<->transit bridge and inherits
the SAME `ip_forward=0` pin requirement (a richer surface than the rack: MAAS region + LXD host).


**STAGE 3 IN PROGRESS (branch `dc-dc-stage3-phase2-dc-substrate`) -- two rulings landed 2026-07-15.**
Walked the phase2 runbook and surfaced its blocking decisions; the operator ruled both:
- **D-121 (ADOPTED IN PART).** VR1 makes the decorative single-unit control plane REAL: 14 services
  scale 1->3 (the 12 hacluster-backed APIs + ceph-radosgw + rabbitmq + vault; `ceph-rbd-mirror` stays
  1 per D-108). This is D-009's "mechanical 1->3" pulled forward from Roosevelt -- but it is a PLACEMENT
  rewrite (every app's `to:` must spread across 3 distinct hosts), not a num_units tweak. **Node layout
  = Option C** (3 control + 2 compute + 3 storage per DC, 16 node VMs), ruled after a whole-host
  validation PROVED it fits: measured budget 256 vCPU / 1024 GiB / 10 TiB, Option C allocates
  222 / 790 / 5.4Ti (RAM binding at 77%; model at `scratchpad/optc-calc.py`). Ruled sizing: control
  16/64GiB/150GiB, compute 12/48/100, storage 8/24/550; keep control <=64 GiB (96 GiB -> 96% RAM).
  **Vault-HA sub-ruling RESOLVED = (v-a)** (2026-07-15): keep MySQL-backed (on the already-3-unit
  mysql-innodb-cluster), scale to 3, re-add `vault:ha`. GATE: verify the `1.8/stable` vault charm does
  HA on the MySQL backend with 3 units; if not, evaluate Raft (NOT etcd) via D-068. 3-unit vault
  triples the unseal burden (intersects OPEN SEC-003).
- **D-122 (ADOPTED).** VR1 site shape: each site nested in its own containment VM (site-down/recovery +
  site-to-site drills); dark fiber DC-DC-Office is East-West ONLY; each site has its own dedicated L3
  ISP uplink (build `vr1-dc0-wan` on the office1-wan pattern); DC edge follows the Office1 pattern
  (2048MiB/2vCPU/nano, REST-API config, LAN faces the site network); each site its own MAAS controller.
  Subsumes the DOCFIX-185 D-100/D-107 amendment note.
- **Fix-forward DONE (2026-07-15):** the phase2 runbook is reconciled to post-D-119 naming
  (`vr1-dc0`/`vr1-dc1`, bare `dcN` rejected) and its obsolete Steps 4-5 rewritten to the D-113(a2)
  REST-API bootstrap (the module already dropped `config_iso_path`); the D-121/D-122 rulings folded in
  so its Ruling-1/Ruling-2 STOP-gates clear. Honest achievable first-run scope stays **Steps 1-8** --
  Step 9 (MAAS registration) gates on the per-DC MAAS "rack controller", now RESOLVED IN PRINCIPLE by
  **D-123** (PROPOSED, recommend Model A): it is just a `vvr1-dc0` site headend VM (the proven Office1
  pattern -- `cloudinit-vm` like `voffice1` + `scripts/site-headend-install.sh`, which already names
  `vvr1-dc0` as a target). Once Model A is ruled it is prepare-able (opentofu block + Step-9 wiring),
  which effectively closes the Stage-4 gap for Step 9. D-123 also reconciles the D-122 "one virsh
  destroy = site-down" wording (literal for Office1; for a DC, site-down = destroy the `vr1-dc0-*`
  domain group). See `docs/changelog-20260715-d121-d122-stage3-ha-nodelayout.md`.
- **EDGE NIC MODEL RULED (D-122 refinement, 2026-07-15): 2-NIC, baremetal-matched.** NIC count mirrors
  the Roosevelt hardware -- **nodes = 6 NICs** (one per plane, measured on VR0 openstack0-3), **edge = 2**
  (WAN + LAN). The six planes are **routed by the fabric** (OVN/OpenStack on the deliberately isolated-L2
  `dc-planes` segments), so the edge is NOT an inter-plane router -- only the external boundary. No
  `opnsense-edge` module extension needed. Edge **WAN = `vr1-dc0-wan`** (`172.30.2.0/24`), edge
  **LAN = provider-public** (`10.12.4.0/22`; edge is the external gateway per D-100). This SUPERSEDES the
  earlier "build an office1-network-analog site LAN" flag -- no new site-internal segment is needed.
- **STAGE-3 PREP BATCH DONE 2026-07-15 (authoring + offline validation; NOTHING applied).** See
  `docs/changelog-20260715-stage3-prereqs-prep.md`. Gauntlet ALL GREEN (61), `tofu validate` Success,
  repo-lint 0-fail.
  - **OpenTofu:** new `modules/site-wan` (NAT /24 uplink; schema confirmed via `tofu providers schema`,
    validated) + `main.tf` Stage-3 section wired (NOT APPLIED): `vr1_dc0_wan` (172.30.2.0/24), the 2-NIC
    edge (LAN=provider-public, WAN=uplink), 8 Option C node VMs via `for_each` (metal-admin PXE-first),
    netem HELD (Step 11; mesh bridge = virbr7 measured), stale `vr1_dc1_planes` comment fixed. **HELD
    pending D-123:** the `vvr1-dc0` headend + `maas-vm-host` (Step 9) blocks.
  - **NetBox:** `netbox/dc-edge-wan-import.py` + harness (58/58) -- registers the two DC-edge /24s
    (172.30.2/3.0/24, role edge, site-scoped), DRY-BY-DEFAULT with whole-plan preflight. READY to
    `--commit` (command in the tool header; token operator-held; guard blocked the live read).
  - **Bundle HA overlay:** `overlays/dc-ha-scaleup.yaml` (Stage-5 prep) -- 14 services ->3, one-per-
    control-node placement (`{{VR1_DC0_CONTROL_0N}}` tokens, Stage-4-bind), + 3 correctness items the
    agent caught: rabbitmq `min-cluster-size:3`, hacluster `cluster_count:3`, re-declare `vault-hacluster`
    (BUNDLEFIX-002 had commented it out) + re-add `vault:ha`.
  - **The failed opentofu agent** (transient API stall, wrote nothing) was covered in-session by the main
    loop; the netbox + overlay agents completed clean.
- **D-123/D-124 RULED + `vvr1-dc0` RACK WIRED (2026-07-16).** D-123 Model A + MAAS region-on-Office1 +
  rack-per-DC; D-124 Scheme A (office1<->dc0 mesh transit /30) + rack sizing 4/8192/80. `main.tf` now
  wires **`module "vvr1_dc0"`** (cloudinit-vm, 4/8192/80, two legs: metal-admin + mesh-office1 transit,
  static IPs from NEW tfvars `vr1_dc0_rack_*` -- NetBox-assigned, not invented; interface-naming trap
  flagged) + a `mesh-link` `network_name` output. `tofu validate` Success; opentofu-validate 11/11.
  **Step-9 `maas-vm-host` STAYS DEFERRED (DOCFIX-179):** adding the `provider "maas"` block would force
  every plan (incl. the Steps 1-8 apply) to demand MAAS creds, and vr1-dc0's MAAS doesn't exist until
  vvr1-dc0 is up -- wire it as its own step once the rack MAAS is reachable. The rack MAAS INSTALL needs
  a rack-only mode of `site-headend-install.sh` (follow-up).
- **D-124 rack-mgmt importer BUILT (2026-07-16):** `netbox/dc-rack-mgmt-import.py` + harness (96/96),
  parameterized (`--transit-cidr`/`--rack-ip`, no invented literal), whole-plan preflight. Gauntlet 62.
  **Two operator preconditions it flags before `--commit`:** (a) SEED a dedicated `transit` role in
  office1-netbox (none exists; `infra` is shared, not reused) -- die-if-absent, like `edge`; (b) DECIDE
  the transit supernet -- the importer assumes it nests under `10.12.0.0/16` (Cloud), but D-124 mirrors
  the Edge role (which got its OWN `172.30.0.0/16`), so a dedicated mgmt/transit supernet may be wanted
  (then a one-line `CONTAINER` const update). Transit prefix scope = site vr1-dc0 (region may be preferred).
- **RESIDUAL for a smooth batch deploy:** (1) NetBox: seed the `transit` role + decide the transit
  supernet, then run the D-124 importer (+ the D-115 DC-edge importer) `--commit` with the assigned CIDR/
  IP, then fill the `vr1_dc0_rack_*` tfvars; (2) runtime: `opnsense-prep-image.sh` for the edge nano;
  (3) Step-9 maas-vm-host wiring once the rack MAAS is up (**the rack-only `site-headend-install.sh --role
  rack` mode is now DONE, 32/32** -- it enrolls a DC rack to Office1's region; `maas init rack` confirmed);
  (4) Stage-4: render the HA overlay's control-node machine IDs + `--overlay --dry-run`; (5) D-121
  verifies (vault MySQL-HA at 3; hacluster cluster_count). All operator-gated / Stage-4.
- **`main.tf` stale comment (flagged):** the commented `vr1_dc1_planes` block (~L38-50) still says
  "wait for NetBox to assign D-101's supernet" -- STALE per D-115 (assigned `10.12.64.0/19`). Doc-only
  pass did not touch `main.tf`; the `main.tf` owner should correct the comment.
- **STALE gate corrected:** the runbook + `main.tf` say `vr1-dc1` is blocked on "NetBox assigning the
  supernet" -- D-115 ALREADY assigned it (`10.12.64.0/19`, imported to office1-netbox). vr1-dc1 stays
  out of scope this pass by SEQUENCING, not a missing literal. Do NOT uncomment `vr1_dc1_planes`.
- **Logged, NOT executed (adjacent improvement, hard rule 1):** promote `scratchpad/optc-calc.py` into
  a committed whole-host capacity calculator with a harness (sibling to `dc-dc-ceph-disk-budget.sh`).

The authoritative per-stage tracker is `docs/dc-dc-deployment-workflow.md` (stage table + tooling
gap register). Read it FIRST. This list is only what that doc does not already carry.

1. **Stage 2 -- the Office1 HEADEND IS LIVE and D-114 is PROVEN END TO END (2026-07-13).**
   `voffice1`: Ubuntu 24.04.4, 16 vCPU / 32 GiB / 600 GiB, **10.10.0.20** (Kea reservation, outside
   the pool), egress through the OPNsense edge. On it: **MAAS 3.7.2** region+rack (PostgreSQL 16.14)
   and **LXD 5.21.5**, with that LXD **registered into MAAS as an LXD VM host**. MAAS then
   **composed, PXE-booted and COMMISSIONED** `office1-netbox` (LXD VIRTUAL-MACHINE, leased
   10.10.1.100 from MAAS, reached status **Ready**, 2 cores / 4096 MiB detected).
   **The L3 nesting proof is now DEFINITIVE** -- a guest booted, PXE'd and commissioned three levels
   deep, not merely "`/dev/kvm` exists". VR0's `lxd` + `tailscale` pattern, reproduced.
   Codified in `scripts/site-headend-install.sh` (+ harness, 18/18) -- reusable for DC1/DC2.
   **THE DHCP SPLIT (structural, not conventional):** `10.10.0.0/24` -> **Kea** on the edge (MAAS
   dhcp_on=False); `10.10.1.0/24` (`lxdbr0`) -> **MAAS** (dhcp_on=True). Separate L2s; `lxdbr0` is
   NEVER bridged onto the site LAN. The install script hard-fails if MAAS DHCP is on any other subnet.
   **OFFICE1 IS ESSENTIALLY COMPLETE (2026-07-13).** `office1-netbox` (10.10.1.10) runs **NetBox
   4.6.4**; `office1-tailscale` (10.10.1.11, tailnet 100.64.0.53) is a subnet router advertising
   `10.10.0.0/22` on the operator's **SELF-HOSTED** control plane. The edge routes `10.10.1.0/24 ->
   10.10.0.20`. Full connection reference: **`docs/vr1-office1-as-built.md`** -- read that first for
   any "how do I reach X" question.
   **GitBucket: OUT OF SCOPE (D-116, operator ruling).** No Office1-local GitBucket is built;
   `git.baldurkeep.com` stays the git service of record. Office1's composed machines are exactly TWO.
   **REMAINING on Office1 (reconciled 2026-07-14):** (a) route enable -- **DONE**, operator enabled
   `10.10.0.0/22` on the control server; the edge GUI answers at 10.10.0.1 from the workstation with
   no tunnel; (b) import the D-115 carve into the Office1 NetBox -- **DONE** (sandbox seeded from the
   upstream draft and PROVEN faithful field-by-field; carve + six-plane roles + BOTH DCs imported,
   90 -> 134 prefixes); (c) the pinned Office1 LAN IPv6 (item 1a) -- **STILL OPEN**, and it is now
   the last build item on Office1.
   **STAGE 2 IS IN CLOSE-OUT, NOT BUILD. It is also the BRANCH MERGE POINT** (see PINNED). The
   close-out checklist C1..C5 is in `docs/dc-dc-deployment-workflow.md`; do not re-derive it here.
1a. **DONE 2026-07-14 -- Office1's LAN IPv6 is LIVE and PROVEN ON THE WIRE. C1 is CLOSED.**
   Address `2602:f3e2:f01:100::1/64` on the edge LAN (kernel-verified) + radvd advertising the prefix
   with `mode=unmanaged`; `voffice1` autoconfigured `2602:f3e2:f01:100:5054:ff:fe6a:87e5` by SLAAC and
   edge->voffice1 GUA ping is 0.0% loss. No collateral damage (v4, Kea DHCPv4, compose-net route all
   intact). See `docs/changelog-20260714-office1-lan-ipv6-executed.md`.
   **OPERATOR RULING 2026-07-14 -- DO NOT RE-PROPOSE A v6 NAT.** A v4-to-v6 NAT (second OPNsense, or
   nginx) was proposed to *simulate* the v6 the lab will not forward, and was WITHDRAWN in favour of
   *"configure IPv6 internally as much as possible; configure the IPv6 edge AFTER deployment
   completes."* It contradicts **D-101** (*"native GUA routing, no NAT66"*) and **D-115**'s amendment
   (upstream's problem, not ours), and a translation box is the one component Roosevelt will NOT have
   -- maximum delta, zero proof value. nginx is an L7 proxy, not NAT, and proves nothing about
   RA/ICMPv6/Ceph-over-v6.
   **TRAP recorded:** `voffice1` has `forwarding=1` + `accept_ra=0` yet STILL autoconfigured --
   netplan/systemd-networkd handles RA in USERSPACE, independent of the kernel sysctl. Never diagnose
   "no SLAAC" from the sysctl alone on Ubuntu; read `ip -6 addr` + look for a `proto ra` route.
   **The WAN v6 leg remains DEFERRED** -- v6 does not egress the lab (re-measured 2026-07-14: v6
   internet 100% loss, v4 fine). Internet GUA reachability is UNPROVABLE in VR1.

1a-historical. **(superseded -- the original pinned item)** deploy Office1's LAN IPv6 (operator ruling 2026-07-13, D-115
   question 3: "register AND deploy dual-stack on Office1 now", sequenced AFTER the NetBox deploy).
   Add `2602:f3e2:f01:100::1/64` to the OPNsense edge LAN + RA, and let `voffice1` take its address.
   **CORRECTED 2026-07-14 (D-113 AMENDMENT -- the old instruction here was WRONG):** the ADDRESS half
   CANNOT be done via the REST API. Measured on the live edge (OPNsense 26.1): `Interfaces > [LAN]` is
   the LEGACY page `/interfaces.php?if=lan`; only Devices and Neighbors were migrated to MVC, and there
   is **NO REST endpoint for a base interface's `ipaddrv6`**. D-113(a2)'s "interfaces are API-covered"
   was INFERRED, never measured, and is false.
   - **Address:** `scripts/opnsense-set-interface-v6.sh` (dry by default; harness 40/40). It is NOT a
     config.xml push -- it mutates two leaves of the edge's LIVE config through OPNsense's own model,
     so API-managed Kea and the firewall rules cannot be clobbered. **WRITTEN AND TESTED, NEVER RUN
     WITH `--commit`.**
   - **RA:** that half IS API-native -- `/api/radvd/settings/addEntry` via `scripts/opnsense-api.sh`.
   Still forbidden either way: a rendered config.xml push.
   **KNOWN LIMIT, do not forget it:** IPv6 DOES NOT EGRESS THE LAB (measured 2026-07-13: v6 gateway
   reachable, v6 internet 100% loss, v4 fine). So this proves v6 ADDRESSING / RA / services-binding,
   which is most of D-101's family matrix -- but NOT internet GUA reachability, which is unprovable
   in VR1 until the lab's upstream carries v6. Deploy the LAN leg; DEFER the WAN v6 leg (it would be
   a path to nowhere and untestable). See D-115's amendment.
1b. **`10.10.1.0/24` IS NOW A BLESSED ALLOCATION (D-115 ADOPTED).** VR1 Office1 = `10.10.0.0/22`
   (Office role, `10.10.0.0/16`): LAN `10.10.0.0/24` + compose `10.10.1.0/24` + 2 spare. Zero
   renumber. Also adopted: Edge role `172.30.0.0/16` (legitimises `office1-wan`'s 172.30.1.0/24,
   which had been squatting in the Corp OOB block), and **DC2 moved to `10.12.64.0/19`** inside the
   Cloud /16 (its old `10.13.0.0/19` sat outside every allocated block). STILL TO DO: write the
   carve into NetBox -- production write is operator-gated; the plan is to import into the Office1
   sandbox NetBox first, verify, then feed back.
1c. **(superseded note kept for context)** the original unblessed-allocation finding: Chosen deliberately (DC1=10.12.x, DC2=10.13.0.0/19,
   tenant pool=10.20.0.0/16 per D-016 -- the obvious `10.20.x` would have COLLIDED with tenant space),
   but NetBox has not assigned it. Register it once NetBox exists. Known chicken-and-egg: NetBox is
   one of the VMs this headend composes.
1c. **`modules/node-vm` nested-virt defect: FIXED 2026-07-13** (operator: fixes land as we find them;
   only DC1 *deployment* is gated). Unconditional `cpu = { mode = "host-passthrough" }` -- DC nodes
   run `nova-compute` and MUST run KVM guests. Without it they would have come up looking healthy and
   been unable to launch a single instance.
2. **NetBox sandbox loop -- DOCUMENTED 2026-07-14 (close-out C4 DONE).** scope-doc section 8 + phase1 runbook Step 10b. (Was: BUILT 2026-07-13/14, undocumented.)
   Architecture: draft-source `netbox.baldurkeep.com` (READ ONLY) -> a NEW NetBox on the Office1 VM
   (sandbox) -> import draft + planned changes -> simulate VR1 there -> feed validated refinements
   BACK. The sim NEVER `--commit`s upstream. **The tooling now exists and is proven:**
   `netbox/prod-draft-dump.py` (read-only, no write path at all), `netbox/sandbox-seed.py`
   (dry-by-default, structurally REFUSES an upstream URL), `netbox/sandbox-fidelity-check.py`
   (field-by-field -- counts alone HID a bug where 17 of 90 prefixes silently lost their region
   scope). **STILL PENDING:** capture the loop in `docs/dc-dc-netbox-buildout-scope.md` + the Stage 2
   runbook, and **ensure `office1-netbox` holds the COMPLETE validated dataset** (close-out C2,
   REDEFINED by DOCFIX-195: `office1-netbox` is the VR1 IPAM apex (the working draft every consuming
   system reads); `netbox.baldurkeep.com` is the production apex, held as a READ-ONLY v1 reference draft,
   and the write-back to it is DEFERRED to end-of-deployment -- NOT a Stage 2 gate).
   **C2 sub-task (i) DONE 2026-07-15** -- the hardened fidelity check was re-run against `office1-netbox`
   (read-only dump via the consolidated sandbox token + an SSH tunnel), and the sandbox is PROVEN
   faithful: exit 0, "upstream draft + EXACTLY the planned delta." Along the way the hardened checker's
   own scope rule was found to FALSE-FAIL on the two intentionally-unscoped role-container /16s
   (`10.10.0.0/16`, `172.30.0.0/16`); fixed to assert scope == INTENDED (now also catches a WRONG-TARGET
   binding -- the D-117 near-miss), harness 10->12, gauntlet ALL GREEN (58). SEC-009 gap closed: the
   sandbox token was never consolidated; it now lives at `~/vr1-office1-creds/vr1-netbox-sandbox.env`.
   See `docs/changelog-20260715-fidelity-check-scope-correctness.md`.
   **C2 sub-task (ii) DONE 2026-07-15 -> C2 FULLY CLOSED -> STAGE 2 CLOSE-OUT COMPLETE (C1..C5 all done).**
   The tooling gap was closed (`prod-draft-dump.py` + `sandbox-fidelity-check.py` now cover
   `ip-ranges`/`ip-addresses`; harnesses +T11/T12 and a new `netbox/d120-compose-bands.py` +16/16
   harness), and the D-120 objects (3 bands + 2 service IPs) were loaded into office1-netbox
   (`--commit`, operator-approved) and VERIFIED: re-dump + fidelity check -> exit 0, "EXACTLY the planned
   delta (D-115/D-117/D-118/D-120)." Gauntlet ALL GREEN (60). D-120 Step 6 CLOSED (no apex write). See
   `docs/changelog-20260715-d120-load-and-iprange-tooling.md`. **NEXT: the branch->`main` merge** (Stage 2
   close is the merge point, PINNED) -- an operator-gated action, present it, do not run it unasked.
3. **`pynetbox` -- CLOSED 2026-07-13.** Installed (7.0.0) on `office1-netbox`, which is where the
   imports actually run. The stdlib tools (`prod-draft-dump`/`sandbox-seed`/`sandbox-fidelity-check`)
   deliberately need no dependency at all.
   **TRAP, recorded in `platform-traps.md`:** the upstream NetBox sits behind a **User-Agent-filtering
   WAF**. `Python-urllib/3.12` gets a **403 that looks exactly like an auth failure**; the same token
   works from curl. This affects pynetbox too.
4. **The apparmor rule is now IN THE REPO -- CLOSED 2026-07-13.**
   `scripts/prereqs/install-apparmor-libvirt.sh` (+ `install-all` / `check-prereqs` wiring; harness
   24 -> 32 PASS; gauntlet ALL GREEN 52). It grants `<pool-parent>/** rwk,` in
   `/etc/apparmor.d/local/abstractions/libvirt-qemu`, which GATES EVERY VR1 VM BOOT: without it a
   domain DEFINES but qemu fails "Permission denied" and nothing in the error names AppArmor.
   Idempotent, and a true no-op on an already-good host (it does NOT reload apparmor or bounce
   libvirtd unless it actually adds the rule). Pool parent defaults to `/var/lib/libvirt/vr1`,
   override with `VR1_POOL_PARENT`. `docs/changelog-20260713-apparmor-libvirt-prereq.md`.
5. **The DEFERRED literals are now ALL ASSIGNED -- item CLOSED 2026-07-14.** The operator's Option-B
   ruling ("do not invent CIDRs, wait for NetBox") held, and NetBox has now assigned them:
   **ORG_ULA_48 = `fd50:840e:74e2::/48`** (**D-118 ADOPTED** -- RFC 4193 valid, and verified NOT to
   collide with Tailscale's `fd7a:115c:a1e0::/48`, which matters because `office1-tailscale` runs
   `--accept-routes`); GUA per D-117: first DC `2602:f3e2:f02::/48`, second `f03::/48`; the second
   DC's v4 = six sequential `/22`s from `10.12.64.0/19` (D-115 moved it INSIDE the Cloud /16).
   All are IMPORTED and fidelity-checked in the sandbox.
   **CAUTION -- `DC2_V4_SUPERNET` IS A RETIRED NAME (D-117).** The importer now hard-rejects it and
   rejects `--dc dc2`. Any doc still saying `10.13.0.0/19` is pre-D-115 and wrong.
6. **D-119 (ADOPTED 2026-07-14) -- THE DC NAMESPACE IS REGION-QUALIFIED. C3/gap #19 CLOSED.**
   `vr0-dc0` (VR0's LIVE testcloud) / `vr1-dc0` (VR1's FIRST DC, GUA f02::/48) / `vr1-dc1` (VR1's
   SECOND, f03::/48). Bare `dcN` is REJECTED everywhere -- it meant VR0's live cloud in `lib-net.sh`
   but VR1's first DC in the importer: one string, two clouds. D-119 **COMPLETES D-117** (executes
   its own amendment); it does not reverse it. **ZERO NetBox writes** -- the apex was already right;
   the REPO was the odd one out. The importer's DC->site map is now an IDENTITY, so the off-by-one is
   STRUCTURALLY IMPOSSIBLE, not merely defended. Also renamed: `vdc1`/`vdc2` -> `vvr1-dc0`/`vvr1-dc1`
   (D-114's own DR primitive is `virsh destroy vdc1` -- it read as "destroy VR1 DC1" while MEANING
   "destroy VR1 DC0"). Office KEEPS its number (`vr1-off1`, `Office1`, `voffice1`).
   Env var: `DC1_/DC2_V4_SUPERNET` -> **`VR1_DC1_V4_SUPERNET`** (both old names rejected by name).
   Gauntlet ALL GREEN (57); dc-selector 21->30, prefixes-import 40->82.
   **THE `tofu apply` IS NOT DONE -- IT IS GATED.** Plan: 11 to add, 0 to change, 11 to destroy (the
   libvirt object NAMES change, which is 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).
   Re-plan at execution and STOP if anything shows ATTACHED.
   See `docs/changelog-20260714-d119-region-qualified-dc-namespace.md`.

6a. **(historical) G5 NetBox site rename -- CLOSED as D-117 (ADOPTED, Option B).** The repo moved to the apex's
   0-indexed convention (first VR1 DC = `vr1-dc0`), rather than bending the apex to the repo. This
   fixed a REAL off-by-one: `dc-dc-prefixes-import.py` bound `--dc dc1` to slug `vr1-dc1` while
   treating `f02::/48` as dc1 -- but the apex binds `f02` to `VR1 DC0`. It would have written the
   first DC's prefixes onto the second DC's site. The importer is now also **dry-by-default**.
   **D-117 IS ONLY PARTIALLY EXECUTED** -- see gap #19 / close-out C3: `opentofu/main.tf` and
   `lib-net.sh`/`lib-hosts.sh` still speak the OLD naming, and `lib-net.sh`'s `dc0` means **VR0's**
   DC0. That collision BLOCKS Stage 3.
   G2 (aggregates) and G3 (ULA /48) are both CLOSED by the same work.
7. **DOCFIX-185 follow-up (operator to rule):** a D-100/D-107 amendment note so the Stage-3 DC
   edges are built to the per-site-ISP transport model (each site simulates its OWN ISP; dark
   fiber is East-West/replication ONLY, never an internet path).
8. `docs/dc-dc-deployment-workflow.md`'s status table was corrected 2026-07-13, but re-read it
   against reality before trusting any row -- it has drifted twice.
9. **DHCP PROVEN END TO END -- CLOSED 2026-07-13.** `voffice1` (the first client ever to sit on
   `office1-local`) took a real lease from Kea: `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. The
   service, not just the daemon, now works.
10. **Doc-accuracy finding (measured 2026-07-13, logged not actioned):** `docs/security-ledger.md`
   SEC-007 says "D-112(c) makes SSH the only management path". MEASURED on the live edge: the web
   GUI IS listening on the LAN side (10.10.0.1:443 HTTPS 200; :80 301-redirects to it), and is
   correctly firewalled OFF on the WAN side (172.30.1.2:443/:80 closed). This is OPNsense-default
   and not an exposure -- the LAN is the office network, and D-113 kept OPNsense precisely BECAUSE
   the GUI is an operator requirement. But "the only management path" is imprecise: SSH is the only
   path used by AUTOMATION. Reword SEC-007/D-112(c) so nobody concludes the GUI is disabled.
   Reaching the GUI from a workstation requires an SSH tunnel via vcloud (the LAN is a host-local
   libvirt bridge, `virbr2`, not routable off-host): `ssh -L 8443:10.10.0.1:443 <user>@10.17.11.248`
   -> `https://localhost:8443`.

**VCLOUD POST-RESTART SWEEP + D-126 BASE-LEG + D-128 OPERATING MODEL (2026-07-17) -- SESSION CLOSED
(committed + pushed; two honest carry-forwards below).** The vcloud host
completed its bookend patch+reboot (running `6.8.0-136`, 0 upgradable, no reboot-required). Full sweep
GREEN: libvirt 12 nets/4 pools active+autostart, both VMs autostart=enable+RUNNING, autostart chain proven
end-to-end (all guests+edge uptime matched host boot). Post-reboot `ssh voffice1` was DOWN -- root cause:
`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 every reboot; D-126 made the
layers above it durable but never owned this base leg. **DELIVERED:** `scripts/site-baseleg.sh` +
`tests/site-baseleg/` (24/24) -- a root `Type=oneshot` unit `After=libvirtd` that re-adds the leg at boot
(bridge DISCOVERED from the net name, not baked; idempotent apply; `check` = read-only session-verify).
Gauntlet ALL GREEN (67), repo-lint 0-fail. **D-126 amendment** + **NEW D-128** (operating model: Claude on
the vcloud jumphost; Plane-1 substrate on vcloud / Plane-2 executes on voffice1; workstation tailnet = human
path; D-107 untouched) recorded; skill invariant + workflow Cross-cutting bullet added. See
`docs/changelog-20260717-d126-baseleg-oneshot-d128-operating-model.md`. **INSTALLED 2026-07-17; boot-race
UNPROVEN:** `install` run (operator sudo) -- unit written + `enabled` (multi-user.target.wants), `apply` ran
at install -> status=0, `check office1` -> ok. That run was POST-boot so it did NOT exercise the
`After=libvirtd`+poll race; boot durability stays UNPROVEN until an ACTUAL reboot shows `ssh voffice1`
self-heals. Ordering MEASURED (monolithic libvirtd active here). **COMMITTED + PUSHED** on branch
`dc-dc-stage3-phase2-dc-substrate`: `1958063` (tool + records + sweep) and `6f26b55` (tooling-gap register
item **20** CLOSED for Office1 + the skill's per-DC discipline). Gauntlet ALL GREEN (67), repo-lint 0-fail,
next-free D now **129**. `main` untouched (stage-close merge deferred).

**CARRY-FORWARDS:**
1. **Boot-race proof -- PROVEN 2026-07-18 (RETIRED).** The operator-forced test reboot (host booted
   2026-07-17 23:38:41) exercised the `After=libvirtd`+poll race, and all four checks PASSED:
   (a) `site-baseleg-office1.service` active(exited) status=0; (b) the unit journal logs
   **`added leg: 10.10.0.10/24 on virbr2`** + `route set: 10.10.1.0/24 via 10.10.0.20 dev virbr2` at
   23:38:53 -- the STRONG proof (leg ABSENT at boot -> the unit CREATED it, not "leg present"); (c) `bash
   scripts/site-baseleg.sh check office1` -> ok; (d) `ssh voffice1` returned live with NO manual `ip`
   command this session. So the D-126 base-leg oneshot self-heals `office1-local`'s dropped L3 leg across a
   real reboot, unattended. (Journal read needed root; jessea123 was added to the `systemd-journal` group
   2026-07-18 + relog so future sessions read unit journals without sudo.) Register item 20 / skill routing
   row stand as the durable mechanism.
2. **DC leg rows.** `site-baseleg.sh` generalizes to the DCs but a DC row is DEFERRED-until-measured (hard
   rule 2; the harness fails on an un-commented DC supernet). At each DC standup, MEASURE the vcloud->DC
   reach and add a MEASURED leg row + install ONLY if that net is isolated (register item 20 / skill invariant).

**OPERATOR PERSONAL KEY pushed to Office1 service VMs (2026-07-18).** On operator request ("push my
id_ed25519 on the vms"), the operator's GitHub-published personal pubkey (`ssh-ed25519 ...J7Zg
JANeumatrix@github`, gh:JANeumatrix) was APPENDED to `~/.ssh/authorized_keys` on **voffice1** (user
jessea123), **office1-netbox** and **office1-tailscale** (user ubuntu) -- ALONGSIDE the `vr1-office1-svc`
service key (service key untouched; the D-126 ProxyJump path is unchanged). Read-only audit first (key
ABSENT on all three), idempotent grep-guarded append, verified 2 keys each. This is a deliberate EXTENSION
of the D-126 per-site-service-key model: the operator's personal identity now has direct login from any
workstation over the tailnet (`ssh jessea123@10.10.0.20` / `ubuntu@10.10.1.10` / `ubuntu@10.10.1.11`).
Pubkey ONLY -- the personal private key is workstation-held, never on the jumphost; login-with-personal-key
still needs the operator to test from a workstation. **Edge (office1-opnsense): operator installs via the
OPNsense GUI** (System > Access > Users > root > Authorized keys) -- a raw `/root/.ssh/authorized_keys`
append is NON-DURABLE (OPNsense regenerates root's keys from `config.xml`); config store audited, personal
key ABSENT there too. **STANDING (per-DC): at each DC standup, add the same personal pubkey to that DC's
service VMs** ("in case I need to log in directly" -- operator instruction), alongside the base-leg per-DC
discipline above. **REMOVAL/ROTATION OBLIGATION:** strip these personal keys at v1 close / teardown (same
class as the SEC key-rotation rows); track if a security-ledger row is wanted.

**OPNsense EDGE 26.7 UPDATE + PLUGIN/ADD-ON REVIEW (2026-07-18).** Operator updated `office1-opnsense`
**26.1.11 -> 26.7** (0 outdated pkgs, no pending firmware). As-built version RECORDED in
`docs/vr1-office1-as-built.md:42` (appendix-B is charm-channels only, no edge row). Operator asked for a
forward-looking plugin/add-on review -> `docs/opnsense-edge-addon-review-20260718.md` (all 104 catalog
plugins categorized) + **D-129 (PROPOSED)** captures the base-edge-profile decision. Near-stock edge:
only `os-git-backup` installed, and **UNCONFIGURED** (php-verified no config node) -> **no config backup is
actually running** -- recommend wiring it to `git.baldurkeep.com` (config-as-code) regardless of D-129.
Review recommendations by bucket: metal-hardware profile (`os-smart`/`os-nut`/`os-cpu-microcode`/`os-lldpd`,
record for Roosevelt, inert in VR1 VMs); sim scaffolding (`os-qemu-guest-agent`, VR1 VM edges only, aids
D-126/D-127 reboot work); diagnostics (`os-iperf` for transit validation); observability
(`os-node_exporter` CONDITIONAL on a COS-scope ruling -- D-105 scoped COS per-DC inside the cloud, edge is
outside); DEFER all security hardening per closed-test posture. **UPDATE 2026-07-18 -- operator directive "install the recommendations + pin the rest".** D-129 now
PARTIALLY RULED: VR1 edge profile **{`os-qemu-guest-agent`, `os-iperf`}** adopted. Live install on
`office1-opnsense` via the D-113 firmware API is **operator-GATED** -- the auto-mode classifier blocked the
agent's `core/firmware/install` POST (cloud mutations stay gated even during batch), so the operator runs it
via `!` (or approves); **verification pending** (confirm the `qemu-guest-agent` DAEMON runs, not just the
pkg, + edge DHCP/NAT unbounced). The "rest" is PINNED (not built now, per advisor -- pin = record at the
step): metal profile {`os-smart`/`os-nut`/`os-cpu-microcode`/`os-lldpd`} -> Roosevelt edge build (inert on
VR1 VMs); `os-node_exporter` -> `dc-dc-phase6` Step 10 gated on COS-edge scope; VR1 profile -> `dc-dc-phase2`
edge section (+ build the reusable profile-installer there); security -> deferred (posture). **FOUR
sub-decisions STILL OPEN** (COS-edge scope, `os-frr`, `os-tailscale`, edge-NTP) -- a one-line directive does
not rule them. As-built row updated (FreeBSD base 14.3->15.1 too).
**INSTALL VERIFIED 2026-07-18 (operator ran the firmware POSTs via `!`):** `os-qemu-guest-agent` package
INSTALLED but NON-FUNCTIONAL -- daemon off + `opnsense-edge` module defines no `org.qemu.guest_agent.0`
libvirt channel (grep-confirmed), so `guest-ping` fails. Functional qga = channel-in-module + service-enable
+ edge RESTART -> DEFERRED to next scheduled edge restart (new DC edges born with the channel). `os-iperf`
did NOT install: two back-to-back firmware POSTs collided on the OPNsense firmware LOCK -> re-run pending
(profile-installer must be one-at-a-time + poll). Records reconciled to this reality (D-129 Verification
note, phase2 pin, as-built). Docs committed on branch `dc-dc-stage3-phase2-dc-substrate` (pushed
2026-07-18, `83876c3..c1ef7ab`).
**AUTONOMOUS PROCESSING 2026-07-18 (operator: "process what you can without me running anything").**
Boot-race carry-forward RETIRED (D-126 base-leg PROVEN across the forced reboot -- `added leg` in the
journal; jessea123 added to `systemd-journal` group so unit journals read without sudo). Built the D-129
profile-installer `scripts/opnsense-plugins.sh` + `tests/opnsense-plugins/` (17/17; gauntlet 68 GREEN) --
closes the "build the installer" pin; encodes one-at-a-time+poll + the qga-channel warning. Logged the qga
channel design (OPT-IN var, default OFF -> no office1/DC0-plan side-effect; mechanism-to-verify on dmacvicar
0.9.8) + the `os-git-backup` operator-input ask. **Still operator-only:** `os-iperf` re-install (classifier-
gated), qga functional enablement (channel+enable+restart), git-backup wiring, the 4 D-129 sub-decisions.
See `docs/changelog-20260718-opnsense-plugins-installer.md`.

**PERMISSION POSTURE UPDATED 2026-07-18 (mutations PROMPT, not classifier-deny).** The `auto`-mode
classifier was HARD-DENYING mutations that matched no rule (edge API POST, settings edits, Skill invokes) --
no approval prompt, so the operator had to run them by hand. claude-code-guide confirmed (doc-cited) that
`ask`/`deny` rules are evaluated BEFORE the classifier, so `ask`-listing the mutation surfaces forces a
prompt. `.claude/settings.json` updated (operator-applied by hand -- editing the permission file is itself
gated; chicken-and-egg): added `ask` for `*opnsense-api.sh POST *`, `*opnsense-plugins.sh apply*`, `*tofu
apply/destroy/import/state rm*`, `*--commit*`, `Edit(.claude/settings*.json)`; added `allow` for the edge
GET + `opnsense-plugins.sh list`. The `Edit(.claude/settings*.json)` ask rules mean the agent can now
PROPOSE settings edits (prompted), no longer hard-blocked. Stayed on `auto`+`ask` (not `default` mode) to
keep read-heavy audits frictionless. See `docs/changelog-20260718-permission-posture-ask-preempts-classifier.md`.
**CARRY-FORWARD (verify after the operator's reload):** the new rules take effect only after a Claude Code
restart. Post-reload, CONFIRM a mutation now PROMPTS (approve/deny/adjust) instead of hard-denying -- the
`os-iperf` install (`OPNSENSE_API_HOST=10.10.0.1 bash scripts/opnsense-plugins.sh apply vr1-edge`, or the raw
`opnsense-api.sh POST core/firmware/install/os-iperf`) is the ready test. If it still hard-denies, the rule
pattern needs adjusting (check the exact command string vs the glob).

## OPEN WORK -- VR0 / DC0 (the running testcloud)

1. **d011 batch-3 live-validation queue** -- `scripts/checks/d011-04-octavia-lb.sh` and
   `d011-05-magnum-e2e.sh` are DRAFTED and mock-tested; the live PASS was recorded in the
   2026-07-06 batch-3 window, but these remain the checks to re-confirm on any rebuild:
   d011-04 `amphora_headroom()` field parsing (safe default HOLDs on a parse miss -- confirm the
   OK path live); the OCCM LB-name-contains-service-name assumption; d011-05 needs a FOIL tenant
   (a 2nd tenant) for its P3 isolation case -- foil1 was offboarded, so onboard one or set
   `VR_FOIL_APPCRED`. Sequence: non-disruptive half first, then `--include-disruptive`.
2. **Script backlog item 3 (remainder):** fold `scripts/vault-kv-health.sh` into `cloud-assert.sh`
   as a section (cloud-assert has its own A1 vault check but does NOT absorb the KV health script
   -- VERIFIED still open), then use the combined gate to regenerate the stale restart-procedure
   runbook.
3. **Script backlog item 5:** `scripts/tenant-cluster-create.sh` -- generalize the stage-6 +
   watch + D-066-evidence wrapper. NOT STARTED (verified absent).
   (Items 6/7/8 -- `keystone-policy-drift.sh`, `cloud-snapshot.sh`, `tests/tenant-acceptance/` --
   are DELIVERED. The old main-chat section called them "not started"; that was FALSE. Reconciled.)
4. **S-class script quality (`docs/script-quality-findings-20260707.md`):** S4/S7/S8a/S8b DONE;
   S6 no-action; S8c ruled WON'T-DO. **S1/S2/S3/S5 (lib-validate adoption on tenant-onboard/
   offboard) are HELD** by the operator until the DOCFIX-126/127 live-verify lands.
5. **DOCFIX-126/127 live-verify is still OPEN** -- the offboard-E0 and onboard-cred-file fixes have
   never been exercised end-to-end (foil1's offboard predated them). The next REAL onboard/offboard
   confirms. Related known gap: onboard cred-write stages 1/2 have no unit coverage.
6. **`test1` orphan user -- approved for deletion, staged, NOT run.** Role-less shell in the
   devteam domain, 0 roles, no resources. Exact gated command (RE-VERIFY role-less at execution):
   `openstack user delete 9a62f88e331f41adb5c9e41225ec8698`.
7. **The handoff doc is stale:** `docs/handoff-20260703-open-items.md` still lists R-3 (D-063) as
   PROPOSED/OPEN. D-063 is `RESOLVED / CLOSED` in `design-decisions.md` (verified). Correct the
   handoff doc.
8. **Upstream reports queued (operator):** magnum `can-upgrade-to` anomaly -- Charmhub magnum
   2024.1/stable latest (r101) is s390x-ONLY, no valid amd64 target, so magnum was EXCLUDED from
   the update window; report to OpenStack Charmers. (The dashboard-TLS upstream bug was WITHDRAWN
   -- operator judged it site misconfig; the draft is retained.)
9. **Barbican `host_href`:** the charm renders a literal `https://None:9312`, suppressing the
   upstream request-derived fallback. Benign (catalog unaffected, exercised fine live). A
   charm-level fix would need its own D-NNN. Logged, not actioned.
10. **v1-close checklist is QUEUED** (handoff section 6) -- gated on D-011 item 6, which is gated
    on the SEC-003 unseal rehearsal.

## OPEN -- NetBox WRITE-PATH BUGS (found 2026-07-14 by adversarial review; LOGGED, NOT FIXED)

These are independent of D-119's naming work. **DOCFIX-195 (2026-07-15) reclassified WHEN they matter:**
C2 no longer writes the PRODUCTION apex `netbox.baldurkeep.com` (office1-netbox is the VR1 IPAM apex;
the `netbox.baldurkeep.com` write-back is DEFERRED to end-of-deployment). So these bugs gate the DEFERRED merge-back, NOT Stage 2
close -- they are what would corrupt the production apex during THAT write. They no longer block C2 or
the Stage 2 merge.

1. **`roles-aggregates-import.py` still dies HALF-WAY through a production write.** The preflight it
   advertises only checks role-NAME collisions. The `ARIN` RIR lookup and `validate_ula_48()` both run
   **after** the role-creation loop has already committed 5 roles. A typo'd `ORG_ULA_48`, or an apex
   without ARIN, writes 7 objects then dies with **no rollback**. The RIR preflight loop is a literal
   no-op (`if ...: continue` + a comment). The harness cannot catch it: it only asserts the STRING
   "PREFLIGHT" appears before the first create. **This is the same bug class that already bit us once.**
2. **`sandbox-fidelity-check.py` can return a FALSE GREEN.** It field-compares only the SHARED objects;
   the planned delta is checked merely as a SUBSET of `EXPECTED_NEW`. So a prefix created with the
   WRONG scope/role/status passes clean -- and if the importer created ZERO of the 36 DC prefixes,
   `extra subset-of expected` still holds and it exits 0 saying "nothing lost, nothing stray."
   **We have been citing this script as proof the sandbox is faithful. It cannot prove delta
   correctness.** It WOULD have caught the historical 17-prefix scope drop (those were shared objects).
3. **`find_role()` dies mid-loop** in `dc-dc-prefixes-import.py` -- roles are resolved lazily INSIDE
   the write loop. Against upstream as it stands today (no six-plane roles), a `--commit` creates the
   site + 4 prefixes then dies on the 5th. No whole-plan preflight.
4. **Same-dumper blind spot:** `sandbox-fidelity-check` compares two dumps produced by the SAME field
   list, so any field the dumper omits is invisible on BOTH sides by construction (prefix `vrf`,
   `tenant`, `vlan`, `tags`, `custom_fields`; site `tenant`/`group`/`facility`). Structurally the same
   shape as the region-scope bug that dropped 17 prefixes.
5. **Duplicate-CIDR collapse:** prefix-keyed dicts in the seeder and the fidelity check collapse
   duplicate prefixes (NetBox permits them, and the importer's own docstring anticipates them vs
   `vr0-dc0`). A whole prefix object can vanish with a green check. Latent -- no duplicates upstream today.
6. **The test fake diverges from reality at the failure point:** `fake_pynetbox.get()` returns
   `matches[0]` on a multi-match where REAL pynetbox RAISES. So the harness cannot catch #5.

**Recommended sequence: fix 1-3 BEFORE C2.** 1-3 are DONE (2026-07-14,
`docs/changelog-20260714-netbox-write-path-hardening.md`): the roles-importer preflight now covers
ARIN + the ULA, the prefixes-importer preflights every role, the fidelity check is BOTH-bounds +
delta-scope-aware, and the test fake raises like real pynetbox. Gauntlet 58 ALL GREEN.
**CONSEQUENCE TO ACT ON:** the sandbox was declared "proven faithful" (2026-07-14) using the
fidelity check BEFORE it was hardened -- i.e. under the version that could FALSE-GREEN. RE-RUN
`sandbox-fidelity-check.py` against the sandbox under the hardened check before trusting that
"faithful" verdict -- this re-run IS C2 sub-task (i) (DOCFIX-195), run against `office1-netbox` (the
VR1 IPAM apex), NOT against the production apex `netbox.baldurkeep.com`. (Not done this session: it
needs the office1-netbox token, which is operator-held; folds naturally into the C2 step.)
Items 4-6 remain LOGGED not fixed.

(Historical rationale: 1 and 3 are partial-write-no-rollback on the production IPAM; 2 is what we would use to prove the write was correct.)

## Operator-gated / PINNED (do NOT re-ask; these are rulings, not open questions)

- **STAGE 2 MERGED -- DONE 2026-07-15 (PR #1, `e468d2e`).** The Stage 2 close-out (C1..C5 all met)
  branch `dc-dc-stage1-phase0-first-exec` merged to `main` via a merge commit -- the first VR1 feature
  merge. `main` IS now trunk-of-record for VR1 through Stage 2; the branch was retired. This is no
  longer an open ruling; it GRADUATED into the STANDING **branch-per-stage + merge-at-stage-close**
  discipline that applies to every stage from here (workflow doc "Cross-cutting discipline"): the merge
  is part of each stage's definition-of-done and remains operator-gated (present it, do not run it
  unasked). Stage 3 branches off the post-merge `main` as `dc-dc-stage3-phase2-dc-substrate`.
- **UPSTREAM APEX WRITE-BACK -- DEFERRED to end-of-deployment (DOCFIX-195, operator ruling 2026-07-15).**
  Seeding `netbox.baldurkeep.com` from the validated `office1-netbox` dataset is a MAYBE at the very
  end, NOT a Stage 2 gate. Until then the apex stays a READ-ONLY v1 reference draft (no write during
  VR1); `office1-netbox` (10.10.1.10) is the VR1 IPAM apex (the working draft every consuming system
  reads). The "NetBox WRITE-PATH BUGS" section gates THAT deferred write, not Stage 2 close. Defers the
  write; does NOT revoke D-010.
- **D-071** ratification -- held for the dedicated pre-DC-DC Juju controller HA/backup planning
  session. Backups now exist (a 902MB controller backup was taken; `juju create-backup` /
  `download-backup` DO exist on juju 3.6 -- the original "removed in 3.0" premise was wrong).
  Controller HA (single-controller, no-HA) is the unresolved half.
- **D-068** off-EOL Vault path (Roosevelt-scale). 1.16 is RULED OUT; vault stays 1.8/stable rev 714.
- **SEC-001 / SEC-004 / SEC-005 / SEC-007:** rotate / flip-to-private / revoke at v1 close.
- **SEC-003:** custodian assignment + second-person unseal rehearsal -- DEFERRED by the operator.
  This keeps `d011-06-vault-unseal` MANUAL and gates the FULL close of D-011.
- **SEC-006** (burned NetBox API token) -- **DEFERRED by operator ruling 2026-07-13 to deployment
  completion.** Until then the token is LIVE and EXPOSED.
- **D-076 is NOT this repo's to work.** D-076..D-099 are a RESERVED source-project band, never
  assigned here (D-110). The dashboard-policy-override workstream and its uncommitted draft live
  in the SOURCE project, not this repo. Operator also pinned it: no D-076 work while devteam are
  running their own tests.
- **quota-vs-capacity: CLOSED** -- operator ACCEPTS as-documented (no quota trim).

---

## Standing lessons and traps (load-bearing; these live nowhere else)

1. **THE EDGE TRAP -- DHCP on Office1 is API-MANAGED.** A full rendered `config.xml` push WOULD
   CLOBBER IT. The old scp/install/reboot path is DELETED (template, renderer, ISO builder all
   gone -- `opentofu/templates/README.md` is a tombstone). Configure the edge via the REST API
   (`scripts/opnsense-api.sh`); mint keys with `scripts/opnsense-bootstrap-apikey.sh`.
2. **"updated in-place" DOES NOT mean "no restart".** A `tofu apply` whose plan says
   `libvirt_domain.vm will be updated in-place` **RESTARTED the guest** (measured: uptime 8:36 ->
   6 secs; ~30s with no routing and no DHCP). "In-place" means the RESOURCE is not replaced -- it
   says NOTHING about the guest staying up. The dmacvicar/libvirt provider redefines the domain to
   apply a disk-list change and BOUNCES it. **Assume ANY apply touching a `libvirt_domain`'s
   devices (DC edges, node VMs) is an OUTAGE. Schedule and gate it as one.**
3. **Do not re-implement vendor internals; call the interface.** OPNsense stores API secrets as
   `crypt(secret,'$6$')` (SHA-512, EMPTY salt). We COULD mint keys offline and seed them -- we
   deliberately DO NOT: it would couple provisioning to a vendor hash format we must keep
   byte-compatible forever, and a mismatch FAILS SILENTLY (keys that never authenticate).
4. **A config ISO can NEVER be read on an OPNsense nano image** (D-112). Any instruction to build
   one is a trap; the dc-dc-phase2 runbook directed people into it for days.
5. **root's shell on the OPNsense edge is `tcsh`, not `sh`.** A `$(...)` inside a quoted remote
   command dies with "Illegal variable name" -- and it dies QUIETLY. This already cost one defect:
   a pre-install snapshot silently no-op'd and the install then ran with no snapshot behind it.
   **Always feed remote commands to `sh -s`.** (The `scripts/opnsense-apply-config.sh` that was
   once wanted here is SUPERSEDED -- that snapshot/scp/install/reboot path is the very config.xml
   path D-113(a2) deleted. Do not build it. The tcsh trap still applies to any SSH to the edge.)
6. **Guide changes must sweep the tenant AI skill in the SAME change.** Skill-lag was caught twice
   (DOCFIX-135/136) and is now ENFORCED by repo-lint L8 (guide<->skill coupling; the guide's sha256
   is pinned, and any guide edit FAILS lint until re-recorded).
7. **The controller model is `admin/controller`,** not `<user>/controller`.
8. **`juju status --format=line` omits workload messages on 3.6** -- this caused a cloud-assert
   false negative (fixed by DOCFIX-087). Don't rely on it.
9. **repo-lint's guards are load-bearing; reword rather than weaken.** L3 (docs must not reference
   missing scripts) correctly went RED on the config.xml tombstones -- the tombstones were reworded,
   the guard kept.

## State facts to remember

- **The beta cluster and the foil1 tenant are GONE** (both confirmed absent by the 2026-07-08
  read-only audit). The long-standing "beta cluster left at node_count=2" note was STALE and is
  retired here. `capi-test-1` and the `lbtest` LB leftover are also gone; orphan sweep reads
  ORPHAN=0, zero unattached floating IPs.
- **devteam is a LIVE tenant** running a self-created cluster (built via Horizon, calico,
  keypair `devteam-key`). Their template has `volume_driver` unset but the cluster DOES get a
  default StorageClass from the cinder-CSI magnum default -- persistent storage works out of the
  box; no template change needed.
- The vcloud host was NOT pristine: 9 orphaned `vr0-*` libvirt nets were torn down; **`wan` was
  KEPT** (dual-stack NAT-out-enp1s0, GUA `2602:f3e2:fe:10::/64`) as the working model for the
  per-site ISP-uplink network.
- MTU has TWO domains: the ISP uplink `enp1s0` is 1500; the host-internal plane/dark-fiber fabric
  is **jumbo, underlay_mtu=9000** (operator ruling; verified on all 10 nets).
- The repo is temporarily **PUBLIC** (SEC-004) -- flip private at v1 close.
- Secrets live jumphost-local and are NEVER committed: `~/vr1-office1-creds/` (edge SSH key,
  root password, API key), `~/vr1-office1-creds/vr1-netbox.env` (NetBox token), `~/tenant-devteam/`, `~/vault-init/`.

## Project-completion (execute after D-011 passes)

- Consolidate the 10 per-phase do-documents into `docs/v1-deploy-runbook.md`.
- Set repo visibility PRIVATE (SEC-004); revoke/rotate the SEC-005/006/007 credentials.
- v2-deferred: SSH on GitBucket (port 29418), IPv6 dual-stack, NetBox import bundle.

## NetBox import -- DONE for Office1; DC import BLOCKED on one operator ruling (2026-07-13)

**Done.** The Office1 sandbox NetBox was EMPTY and had no seeder. Built the two-phase loop
(`netbox/prod-draft-dump.py` READ-ONLY -> `netbox/draft/vr1-draft.json` -> `netbox/sandbox-seed.py`),
seeded 129 objects from the upstream draft, then applied the **D-115 office carve**
(`netbox/d115-office-carve.py`): site `vr1-off1`, roles `office` + **`edge`** (new), and 8 prefixes.
Idempotent, and **verified FIELD-BY-FIELD** against the upstream draft
(`netbox/sandbox-fidelity-check.py`): every shared object is IDENTICAL, and the delta is EXACTLY
`+edge` role, `+vr1-off1` site, `+8` D-115 prefixes. The sandbox is a proven-faithful replica, which
is what makes it a valid baseline for the later feed-back diff. See `docs/vr1-office1-as-built.md` s6.

**Why that check exists:** counts and idempotency CANNOT prove fidelity. The seeder silently dropped
the scope on 17 of 90 prefixes (it mapped only `dcim.site`; most of the VR1 draft is
`dcim.region`-scoped) -- and every count still matched and re-runs were still idempotent. It was
caught by LUCK on a spot-check. The fidelity check is that catch, made deliberate.

**D-117 Option B is only PARTIALLY EXECUTED.** Done: the import path (`dc-dc-prefixes-import.py`) and
`docs/dc-dc-netbox-buildout-scope.md`. NOT done: the `$DC` shell selector (below) and the
forward-looking DC prose in the runbooks. Do not read "D-117 ADOPTED" as "fully renamed".

**D-117 ADOPTED (operator ruling, Option B, DC-only):** VR1's DCs are **dc0/dc1**, matching the apex.
The **office KEEPS its number** (Off1). Fixed the importer's off-by-one site binding and made it
**dry by default**.

### ~~BLOCKED~~ **UNBLOCKED and DONE** -- D-118 ratified the org ULA; both DCs imported

**D-118 ADOPTED:** `ORG_ULA_48 = fd50:840e:74e2::/48` (RFC 4193 valid; **no collision with
Tailscale's `fd7a:115c:a1e0::/48`**, which matters because `office1-tailscale` runs `--accept-routes`
-- an overlap would have been a LIVE tailnet routing conflict). Also corrected a **FALSE claim** in
`changelog-20260711-ula-gen-command-fix.md` that called the value "ratified" when no D-number ever
assigned it -- the same document-asserts-authority failure mode as D-117.

**Imported into the sandbox:** six-plane roles + 2 RIRs + 5 aggregates, then **VR1 DC0 (18 prefixes)
and VR1 DC1 (18)**. The D-117 fix is now **LIVE-PROVEN**, not just offline: `--dc dc0` bound to the
apex site `VR1 DC0` (id=8) and `--dc dc1` to `VR1 DC1` (id=9). ULA reads `DC.NN` in the 4th hextet
exactly as D-111 intends (`fd50:840e:74e2:220::` .. `:350::`).

**Final state PROVEN by `netbox/sandbox-fidelity-check.py`:** the sandbox is the upstream draft plus
EXACTLY the planned delta (D-115 + D-117 + D-118) -- every shared object field-identical, nothing
lost, nothing stray. 90 -> 134 prefixes.

### A REAL BUG in `roles-aggregates-import.py`, found by running it for the first time for real

It checked existence by **slug only**. NetBox also enforces **unique NAMES**. The draft's legacy role
`Replication` (slug `repl`) blocks the six-plane role (slug `replication`, name `Replication`), so it
created 4 roles, **400'd on the 5th, and DIED -- leaving the apex half-populated** with no RIRs and no
aggregates and no rollback. It had **never been run against a NetBox holding the real draft**
(only empty ones) and **shipped with NO harness** -- which is why this survived.

Fixed: the six-plane role is now named **"Replication Plane"** (slug unchanged -- `lib-net.sh`
SPACES6 and the prefix importer look it up), and the script now **PREFLIGHTS every name/slug and
writes nothing unless the whole plan is viable**. `tests/roles-aggregates-import/` created: 16/16.

### (historical) the original blocker

`netbox/dc-dc-prefixes-import.py --dc dc0` cannot run. It requires `ORG_ULA_48`, and that literal is
**still unassigned** -- it is gap **G3** in `docs/dc-dc-netbox-buildout-scope.md`, which *recommends*
`fd50:840e:74e2::/48` (CSPRNG-generated, Global ID `0x50840e74e2`) but **no ADOPTED decision assigns
it** (`grep ORG_ULA docs/design-decisions.md` -> nothing). D-101 explicitly leaves it NetBox-assigned.

Using it anyway would violate hard rule 2 (never use an inferred value), so the import STOPPED here.
This is a decision gate, not a tooling gap -- the tooling is fixed, tested, and ready.

**To unblock:** ratify an org ULA `/48` under its own D-number. Then:
```
ORG_ULA_48=<ratified /48>  DC_GUA_PREFIX=2602:f3e2:f02::/48  --dc dc0     # VR1 DC0
ORG_ULA_48=<ratified /48>  DC_GUA_PREFIX=2602:f3e2:f03::/48  \
    DC1_V4_SUPERNET=10.12.64.0/19  --dc dc1                               # VR1 DC1
```
(`DC_GUA_PREFIX` values are MEASURED off the apex; `DC1_V4_SUPERNET` is assigned by D-115.
`DC2_V4_SUPERNET` is RETIRED -- the tool rejects it by name.)

### Also open (recorded, not blocking)
- **`$DC` shell-selector namespace collision** (D-117 amendment): `lib-net.sh`'s `dc0` means **VR0's**
  DC0, while the importer's `dc0` now means **VR1's**. NOT interchangeable. Proposed fix: region-
  qualify the shell selector to the apex slugs (`vr0-dc0`/`vr1-dc0`/`vr1-dc1`).
- Feed the D-115 carve upstream to `netbox.baldurkeep.com` (operator-gated; the tool refuses a
  non-sandbox target without `--yes-write-upstream`).
- Office1 LAN IPv6 (`2602:f3e2:f01:100::/64` + RA via the OPNsense REST API) -- still pinned.
