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).

DC0 deploy-readiness handoff: per-env-key ruling implemented + netem ruled + prep checklist ...

Prep for a fresh session to run the Stage-3 Phase-2 DC0 build. Nothing applied;
the outer tofu apply remains the first (operator-gated) mutation.

Per-env-key (D-126, operator ruling 2026-07-16, option a): vvr1-dc0 gets its OWN
access key, not office1's. Minted ~/vr1-dc0-creds/vr1-dc0_svc_ed25519 (creds-audit
CLEAN); added variable vr1_dc0_ssh_pubkey_path; vvr1-dc0 cloud-init now installs the
dc0 pubkey (voffice1 keeps office1's key -- only the vvr1_dc0 block changed). Re-
validated + re-planned: outer plan UNCHANGED at 5 add / 0 change / 6 destroy (the
cloud-init edit is create-only content, no new destroys/replaces of live infra).

netem (D-100 gap #11): RULED = placeholder for the rehearsal; final values deferred.

docs/dc0-deploy-readiness.md (NEW): the full readiness state (outer plan verified
safe -- vvr1-dc0 416GiB/108vcpu, 6 empty-plane relocation, 980GiB RAM headroom),
remaining prep (pre-apply / mid-deploy / non-blocking), fresh-session bootstrap, and
the gated A-E deploy sequence. Ledger points at it.

Gauntlet ALL GREEN (65 harnesses incl. the 2 new access harnesses); repo-lint 0-fail;
opentofu-validate clean (both roots + 12 modules). The dc0 private key + local tfvars
stay gitignored/off-repo.

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).

creds-audit: enforce per-site credential consolidation (SEC-009); prevents the DC0/DC1 spread ...

SEC-009 established "all site secrets live in ~/<site>-creds/" but nothing enforced
it, and it had two blind spots: VM-minted secrets (no forcing function to consolidate
-- office1-netbox's sandbox NetBox token went un-consolidated until needed) and silent
sprawl (a loose *.env in ~ had no detector). Standing up DC0/DC1 multiplies both.

Built (operator-directed):
- creds-manifests/<site>.manifest -- declares exactly the secrets a site must hold,
  each with mode + provenance (local, or <vm>:<path> for the VM-minted class).
  vr1-office1.manifest seeded (11 entries); the live folder audits CLEAN.
- scripts/creds-audit.sh <site> -- verifies the live ~/<site>-creds/ against the
  manifest (0700 folder, declared modes, present, non-empty), flags UNDECLARED files,
  and scans the home root for SPRAWL. Reads NO secret values (metadata only; harness
  T7 asserts no cat/head/tail/od/xxd). CREDS_ROOT/MANIFEST_DIR overrides for testing.
- tests/creds-audit/run-tests.sh (7/7) -- missing VM-secret, wrong mode, undeclared
  file, home-root sprawl, non-0700 folder, metadata-only. Auto-discovered by gauntlet.
- dc-dc-phase3 GATE -- non-negotiable close-out: consolidate + manifest each secret AT
  MINT TIME, and creds-audit $DC must be CLEAN before a DC is declared done.
- security-ledger SEC-009 ENFORCEMENT note.

Verified: harness 7/7; live creds-audit vr1-office1 -> CLEAN (also tool-confirms the
sandbox-token gap is closed); gauntlet ALL GREEN (59); repo-lint 0 fail.
