G12 dc1: SEC-016 power key wired + commissioning 9/9 READY -- [V] leg complete ...

- SEC-016 dedicated dc1 MAAS->libvirt power key minted, authorized on the
  rack, installed in the region MAAS snap (per-host ssh config; dc0 SEC-012
  key untouched -- true per-DC isolation); manifest updated (creds-audit CLEAN)
- maas-node-power.sh --commit: power_type=virsh on all 9, each verified by a
  real query-power-state (proves the SEC-016 region->rack path)
- commissioned all 9 -> ALL 9 READY in ~3.5 min (no timeout, no SERVFAIL),
  shapes EXACT to D-121 Option C; dc0's two stacked faults pre-empted by
  pinned MACs + the dc-rack-net forwarder
- G12 [V] leg (dc1 build) COMPLETE; NEXT is close-out + operator-gated merge

G12 dc1: edge bootstrap + v4 addressing COMPLETE (D-112c + D-113a2 proven on 26.7) ...

Edge phase for vr1-dc1, resuming the 2026-07-22 close handoff:
- D-112(c) console bootstrap: SSH + dc1 edge key materialized (payload
  needed util.inc/shell_safe() -- dc0 lesson iv the .b64 artifact lacked)
- key-only SSH verified (15.1-RELEASE-p1)
- D-113(a2) API key minted via vendor model; GET core/firmware/status
  exit 0, product_abi 26.7
- edge addressed: WAN 172.30.3.2/24 gw 172.30.3.1 (egress 0% loss),
  LAN -> 10.12.64.1/22 (ruled provider-public gw), API at new LAN
- interim reach leg removed; rack provider-public leg 10.12.64.2/22 live
- creds consolidated to ~/vr1-dc1-creds/ (creds-audit CLEAN); rack edge-key
  copy shredded -> SEC-015 (transient, remediated)

Two queued findings: bootstrap .b64 missing util.inc; opnsense-bootstrap-apikey.sh
scp transient post-restart-sshd failure (readiness-wait/retry candidate).

CURRENT-STATE G12 row + security-ledger SEC-015 + manifest updated (GA-R1/C1).

D-126: durable rootless agent access to VR1 site VMs (shell + forward) + DC creds prep ...

Establishes durable, rootless jumphost->site-VM access so the recurring
sudo-route friction stops (and generalizes to the DCs). Operator ruled Option A
(SSH via systemd --user / ssh_config ProxyJump), advisor-conferred.

Shell layer (FOUNDATION, EXERCISED): scripts/site-ssh-config.sh generates
~/.ssh/config.d/vr1-sites ProxyJump aliases (voffice1, office1-netbox,
office1-tailscale, office1-opnsense). All four aliases proven live from the
agent's session after the operator installed with the one-key office1 env key --
key read from IdentityFile, no creds path in any command (clears the guard hook).

Forward layer (convenience, reviewed-but-unexercised): scripts/site-forward.sh
holds a systemd --user SSH local-forward -> http://127.0.0.1:8000 for office1-netbox.

Secrets boundary: the key is operator-supplied via --key (a PATH, never read/baked);
generated fragments name that path and are written locally (not committed).

DC prep: per-env-key isolation (operator ruling) -- each DC gets a DEDICATED key in
its own ~/vr1-dc<N>-creds/ folder, minted at deploy. Folders pre-created (0700);
creds-manifests/vr1-dc{0,1}.manifest declare the keypairs. DC ssh aliases deferred
until their IPs are measured post-apply.

Also: D-124 dc0 rack tfvars written locally (opentofu/d124-rack.auto.tfvars,
gitignored) -- the independent `tofu plan` unblocker. vr1_dc1_rack_* NOT written
(no ruled dc1 addressing; variables absent) -- STOP flagged for an operator ruling.

Tests: site-forward 38/38, site-ssh-config 30/30; repo-lint 0-fail (1 legacy WARN).
