The node-tunnel PIA credentials (username/password/.ovpn) live host-side in Ansible vault per
docs/07. The encrypted vault.yml was provisioned but never committed, so the vpn.egress.gateway
playbook was not reproducible from a fresh checkout. Commit it (ansible-vault encrypted; the
vault password stays out of the repo via ansible.cfg vault_password_file).

The down-script previously flushed the kill-switch source set on tunnel-down, which
disarmed the 'ip saddr @vpn_egress_gateway_src oifname != tun0 drop' rule exactly when
the tunnel was down — leaving fail-closed to ride only on the stale SNAT source being
non-routable (could leak if the edge NATed it). Retain the set instead: the drop rule
stays armed so any vpn-class packet leaving the WAN while the tunnel is down is EXPLICITLY
dropped (edge-independent). Safe because the up-script flush+re-adds the source on every
reconnect. Validated behavior: WS-NET fault-injection on k3s-dev-3 (2026-08-24).

Author the vpn_egress_gateway role + playbook that stands up the NODE-level
PIA OpenVPN tunnel on egress-gateway node(s) — the host half of ADR-0015. The
CiliumEgressGatewayPolicy steering vpn-class pods is separate GitOps against the
same contract (group vpn_egress_gateway, node label
homelab.keithjackson.dev/egress-gateway=true, host iface tun0).
Honors all four ADR-0015 invariants:
- Split-tunnel (inv 1&2): OpenVPN route-noexec + pull-filter ignore
redirect-gateway => installs no routes; policy routing in a dedicated table
(51820) with `ip rule from <tun0-addr>` steers ONLY Cilium-SNAT'd vpn-class
traffic. Node default route stays on the WAN, tunnel up or down.
- Scoped nftables kill-switch (inv 3&4): own inet table, policy accept, drops
only tunnel-sourced (@vpn_egress_gateway_src set) packets not leaving tun0 =>
vpn-class fails closed (blackhole), node/internet-class fail open (WAN),
never matched.
PIA creds + the proven sweden-aes-128-cbc-udp-ip .ovpn come from Ansible vault
(host-side per ADR-0015/docs-07); vault keys documented, no secret values
committed. ansible-lint (production) + yamllint clean. Not deployed: green
conformance is gated on the live tunnel (operator host creds) — see role README.

The deployed cluster has TWO default StorageClasses — k3s's built-in local-path
AND longhorn — which is ambiguous for PVCs without an explicit class. Longhorn
(ADR-0003) is the cluster storage, so add local-storage to k3s --disable. Effective
on fresh installs (the k3s install task is idempotent → no restart of the running
cluster); the running dev cluster keeps both defaults harmlessly (all platform PVCs
pin storageClassName: longhorn). Rebuilds get a single default.

Two dev.sh gaps surfaced while running bootstrap/sops/install-age-key.sh:
- kubectl defaulted to localhost:8080 (connection refused) because KUBECONFIG
was never set in the toolbox. Set KUBECONFIG=/work/infra/ansible/.cache/dev.kubeconfig
(override via DEV_KUBECONFIG); --network host already reaches 10.73.0.11:6443.
- age-keygen.sh writes the PRIVATE key to ~/.config/sops/age/keys.txt, but that
path was not mounted in the --rm container, so the key was lost on exit. Mount
${HOME}/.config/sops -> /root/.config/sops (created first) so the key persists
on the host and SOPS_AGE_KEY_FILE resolves to it.

Implements T-1.5 findings F1/F2 (author-first, no cluster change).
F1 (tofu): refactor libvirt node resources count -> for_each keyed by
node name so single-node -replace/destroy cannot cascade to siblings.
Add ordered-list/primary helper locals; update outputs.tf off the map;
add moved.tf (12 moved blocks). tofu plan proves a pure state-address
migration: 0 to add, 0 to change, 0 to destroy (all 12 'has moved to').
State-persist via a 0-change apply is operator-permission-gated.
F2 (ansible): k3s_server secondary fetches the join token via
delegate_to the primary (published fact as fast path), so a single-node
rejoin with --limit k3s-dev-N is self-contained and no longer depends on
a fact an earlier play had to set. Syntax-check + CI gate green.

host-prereqs.yml opened the firewall (via the operator's ansible-vault become
password); Flux GitRepository READY=True (main@sha1:a2f3bdc). Commit the
encrypted hypervisor vault (ansible_become_password) so rebuild is fully
hands-off; passphrase stays out-of-repo. platform/apps still not reconciled.

Where the sudo password goes, codified:
- inventory: new [hypervisor] group (localhost, connection=local).
- host-prereqs.yml targets 'hypervisor'; become password from vaulted
group_vars/hypervisor/vault.yml (ansible_become_password) — user creates it
encrypted (safe to commit); README documents the exact commands.
- ansible.cfg vault_password_file = ~/.config/home-k3s/ansible-vault-pass
(passphrase kept OUTSIDE the repo, never committed).
- ci/yamllint.yaml ignores **/vault.yml (vault blob isn't parseable YAML).
Nodes keep NOPASSWD sudo (group_vars/all) — vault scoped to the host only.

Per operator: the firewalld rule (VM->host:3000 for the Flux<-Gitea source) must be
IaC, not a manual command (R-ENV-01, R-PLAT-04).
- infra/ansible/playbooks/host-prereqs.yml: idempotent firewalld open on the libvirt
zone (localhost play, become; no extra collection).
- bootstrap/gitea/bootstrap-gitea.sh: now fully automates admin + public repo + push
(was manual instructions) — idempotent; creds stay 0600 on host, never committed.
Applying host-prereqs still needs host sudo (I lack non-interactive sudo); with
passwordless become a destroy/rebuild is fully unattended.

Cluster is UP (3/3 Ready, Cilium OK); Phase 1 paused before Flux bootstrap
(Option A: suspend platform/apps until Phase 2). Add infra/PHASE1-STATUS.md
(what's done, state file locations, reconnect steps, remaining T-1.4/1.5,
Phase-2 platform prereq), infra/cluster.sh (status/start/stop/kubeconfig), and
document that tofu+ansible run on the host (libvirt provider limitation).

Run a single Gitea container on the host (bootstrap/gitea/), outside the cluster,
while the cluster is built; Flux pulls this repo from it over the k3s-dev NAT
gateway (http://10.73.0.1:3000/Home-Network/home-network-k3s-impl.git, public repo
=> no creds, NAT-only). Wired the flux-system GitRepository url in clusters/dev.
Migrates to in-cluster Gitea in Phase 6. Pins confirmed. Author-only; gate PASS.

Per operator rule: OpenTofu/age/sops/flux are Go binaries, so bake the toolchain
into a pinned Fedora-44 dev container (matches host libvirt 12) instead of a venv.
infra/devcontainer/: Containerfile + versions.env (tofu 1.9.0, age 1.2.1, sops
3.9.4, flux 2.4.0, kubectl 1.32.0, helm 3.16.0) + dev.sh (runs with host libvirt
socket + repo + ssh mounted) + README. Built & validated: all tools resolve;
virsh reaches host libvirt from inside the container.
Also record resolved Phase 1 decisions in PHASE1-SCOPE.md (6GiB/4vCPU x3;
k3s-dev NAT 10.73.0.0/24; container toolchain). Gate green.
