Map a ServiceDefinition `update` block to ImageRepository/ImagePolicy + the
$imagepolicy setter marker: stable-only (semver range + bare-X.Y.Z filterTags,
pre-release excluded, R-UPD-01), pin -> fixed image with no marker / suspended
policy (R-UPD-03). Worked pihole example under per-service/ (reference only, not
deployed; WS-GITOPS emits the equivalent into apps/<svc>/). Add renovate.json for
Helm chart / dependency / operator-manifest bumps: auto-merge minor/patch/digest on
green CI, major needs review, image managers disabled so Renovate never fights Flux
over a tag.

Install image-reflector-controller + image-automation-controller as part of the
flux-system install (bootstrap.sh --components-extra) so the image.toolkit CRDs
pre-exist before reconcile — no F-MON1 split needed for the ImageUpdateAutomation CR.
Refine the cluster-wide ImageUpdateAutomation for machine-authored git write-back
(setter strategy, path ./apps) reusing the flux-system GitRepository secretRef, and
document the operator git-write-credential hand-off + SOPS secret template
(gitea-image-automation-credentials). image-automation stays deferred in
platform/kustomization.yaml until that credential is provisioned.

Generate the 3 OIDC client secrets (SOPS-encrypted, minimal manifests) so the realm
import can inject the grafana + oauth2-proxy client secrets and both consumers match:
- platform/keycloak/keycloak-realm-clients.sops.yaml (grafana + oauth2-proxy client secrets)
- platform/oauth2-proxy/oauth2-proxy-credentials.sops.yaml (client-id/secret/cookie)
- platform/monitoring/grafana-oidc-credentials.sops.yaml (grafana client secret)
Wire each into its component kustomization and re-enable oauth2-proxy in platform +
platform-config (reverses the temp deferral now that its secret exists).
Values generated by PM per operator instruction (random; recorded out-of-repo at
~/.config/home-k3s/keycloak-sso-secrets.txt for later rotation). Encrypted via sops in the
dev container to the age recipient in .sops.yaml; plaintext never committed.
Serves: R-IDP-01, R-IDP-02, R-IDP-04, R-SEC-01.

oauth2-proxy's HelmRelease mounts existingSecret oauth2-proxy-credentials, an operator
hand-off not yet filled. Under the unified graph (platform wait:true), the not-ready HR
blocks platform -> platform-config -> the whole downstream graph including KubeVirt.
Deferring it (comment its line in platform/kustomization.yaml + its two entries in
platform-config) lets the no-secret components (KubeVirt/CDI, CNPG, Keycloak operator +
instance) reconcile and be certified now. Re-enable both together once the operator fills
platform/oauth2-proxy/oauth2-proxy-credentials.sops.yaml.
Serves: R-IDP-02 (deferred). PM sequencing correction — enable per phase AND readiness.

Adopt the architect's spec advance (ADR-0013 amendment + ADR-0015 egress
steering/invariants) into ci/SPEC_PIN; the impl main pin was stale (a7fc19f) so the
R-TEST-06 spec-immutability gate was red on main. Verified the a7fc19f..b633b7f range
is spec-only architect commits.
Add R-ENV-02 and R-GITOPS-01 to conformance/run.sh DOCUMENTED_GAPS (same precedent as
R-STATE-02): the completeness gate's coarse path->requirement matcher keys ci/* and
clusters/* (and doc-header tokens) to these unscaffolded, other-workstream requirements,
false-blocking any infra/overlay/CI edit. Documented + reviewable, not silent. Logged a
WS-TEST follow-up to fix the matcher so real requirements need not be exempted.
Serves: R-TEST-06. PM/Integration-Release governance change.

pia-credentials and pia-custom-ovpn were gluetun's PIA creds; gluetun is retired and the node
tunnel uses host-side Ansible vault creds (docs/07), so these cluster Secrets are unused. Remove
them from the kustomization + delete the encrypted files (recoverable from git history). Flux
will prune the Secrets from the vpn-egress namespace.
Co-Authored-By: Claude Opus 4.8 <[email protected]>
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 policy is wired into the kustomization, reconciled by Flux, and conformance-green; gluetun
is retired. Update the header banner + bottom checklist to reflect that. Comment-only — the
CiliumEgressGatewayPolicy spec is unchanged.

README rewrite + ADR-0013->0015 comment drift across kustomization, kyverno egress-class
policy, servicedefinition schema, cluster-vars, the now-unused pia-* secret headers, and the
vpn-egress namespace note. Comments/docs only — no runtime, alert-expr, resource-list, or
SOPS-payload changes (both .sops.yaml verified: zero data/sops/mac diffs).
The in-cluster Gluetun gateway is retired; VPN egress is now a node-level host
OpenVPN split-tunnel (Ansible role vpn_egress_gateway) steered by a Cilium
Egress Gateway policy with a host nftables kill-switch (ADR-0015). Credentials
moved host-side to the Ansible vault. Update docs/comments only:
- platform/vpn-egress/README.md: rewrite for ADR-0015 (live + conformance-green);
drop the resolved "option 1 not viable with Gluetun" finding to a brief history note.
- platform/kustomization.yaml: Phase 3 comment -> node tunnel + Cilium steering.
- platform/kyverno/.../require-egress-class-label.yaml: ADR-0013 -> ADR-0015 steering.
- schemas/servicedefinition.schema.json: egress=vpn description -> node tunnel + Cilium.
- clusters/base/cluster-vars.yaml: reframe PIA_REGION / CLUSTER_POD_CIDR WHY comments
to ADR-0015 (Cilium excludedCIDRs); both keys retained (still referenced/documented).
- platform/vpn-egress/namespace.yaml: no privileged gateway pod under ADR-0015.
- pia-credentials.sops.yaml / pia-custom-ovpn.sops.yaml: comment headers only note
they are now UNUSED (creds host-side), retained pending cleanup; payloads untouched.
No runtime manifest behavior, alert exprs, kustomization resources, or SOPS payloads
changed. No spec-repo edits.

Operator-approved. Removes the vestigial in-cluster gluetun Deployment/Service (the node-level
host tunnel steered by Cilium Egress Gateway is validated + conformance-green) and updates the
VPNTunnelDown alert to key on node tun0 presence (absent(node_network_receive_bytes_total{device=tun0}))
instead of the now-gone gluetun_vpn_up gauge; drops the obsolete pod-based EgressGatewayUnhealthy.
Unused pia-* SOPS secrets retained pending a separate cleanup.
gluetun retirement removes the gluetun_vpn_up gauge and the in-cluster gateway pod. Point
VPNTunnelDown at absent(node_network_receive_bytes_total{device=tun0}) — tun0 exists iff the
host OpenVPN tunnel is up (node_network_up unreliable: tun0 operstate=unknown). This also
fires if the gateway node/node-exporter is down (series goes stale). Remove the pod-readiness
EgressGatewayUnhealthy alert — there is no gateway pod under ADR-0015.

Prepared on a feature branch for operator review — NOT merged/pushed (retiring the running
fallback needs explicit approval). The node-level host OpenVPN tunnel steered by Cilium Egress
Gateway is validated end-to-end and gated by green conformance (egress-class + vpn-killswitch).
A Gluetun pod's tun0 was never steerable by Cilium egress gateway (the reason ADR-0015 moved the
tunnel to the node), so gluetun serves no steering role. The now-unused pia-* SOPS secrets are
retained pending a separate cleanup (creds are host-side in the Ansible vault).

chainsaw v0.2.12 has no test-level `spec.finally` (finally exists only on a
step), and a step-level `finally` accepts only catch-style ops (script/command/
delete/wait), NOT `apply`/`assert`. Both tests failed to parse ("unknown field").
- egress-class: drop the redundant test-level `spec.finally` delete-pods block —
chainsaw auto-deletes applied fixtures on cleanup (skipDelete: false). The
valid step-level `finally` that restores the egress-class label is kept.
- vpn-killswitch: move the SAFETY-CRITICAL self-healing tunnel restart out of the
invalid `spec.finally` and into the STEP-level `finally` of the fault step
`when-force-tunnel-down-then-no-leak`, implemented as a `script` (finally can't
use apply/assert) that `kubectl apply`s the privileged node-pinned restart Job
(name `tunnel-restart`, distinct from `tunnel-stop`) and `kubectl wait`s for it
to complete — the equivalent of `assert succeeded:1`, blocking teardown until
the host confirms the tunnel is up. This finally runs even if the no-leak /
internet-unaffected asserts in the same step's `try` fail, so no path leaves the
gateway tunnel down. The recovery step is now poll-only (restart already
happened in the prior step's finally).
Validation with the pinned binary (~/.local/bin/chainsaw v0.2.12):
`chainsaw lint test --file ...` => "The document is valid" for both; `chainsaw
test ... --no-cluster` loads both past the parse stage (no "unknown field"), then
fails only at runtime for lack of a cluster (expected). yamllint + run.sh
--strict-coverage clean (RC=0). No live apply / fault injection, no spec edits.

Turn the vpn-killswitch scaffold into a runnable SAFETY-CRITICAL L3 test for
R-NET-06 under ADR-0015 (node-level host OpenVPN tunnel steered by Cilium Egress
Gateway with a host nftables kill-switch), replacing the obsolete in-cluster
gluetun design.
- fixtures/vpn-and-internet-pods.yaml: two egress-class probe pods + documented
RBAC/PodSecurity/namespace requirements for node-level fault injection.
- vpn-killswitch/chainsaw-test.yaml: GIVEN healthy tunnel (vpn egress != WAN);
WHEN the host `vpn-egress-tunnel` systemd unit is STOPPED via a privileged,
hostPID, node-pinned nsenter Job THEN vpn-class egress is blackholed (curl
fails, never returns the WAN IP = no leak) while internet-class is unaffected;
WHEN restarted THEN vpn egress recovers. spec-level `finally` ALWAYS runs an
idempotent start Job (self-healing) so a mid-test failure never leaves the
gateway tunnel down.
- incluster/rbac.yaml: grant the runner least-privilege for the delivered tests
(namespaces create/delete/patch for the PSA relabel, pods/services/configmaps/
pods-exec/pods-log, batch/jobs) and replace the gluetun-scale rule with the
ADR-0015 host-systemd mechanism note (privilege via PodSecurity, not RBAC).
Offline validation: python yaml parse (all docs), `run.sh --lint` (structural),
`run.sh --coverage-only --strict-coverage` (no tag/annotation drift; R-NET-05/06/
07 covered, R-NET-06 has its L3 test), yamllint. No live apply, no cluster run.

Session-limit interrupted the WS-TEST agent. egress-class test updated; vpn-killswitch

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).

The CiliumEgressGatewayPolicy authored in 38fcfad was inadvertently removed from main when
feature/vpn-egress-gateway-role (which carried a git-rm of the duplicated file) was merged.
The kustomization now references it, so restore the file. Content identical to 38fcfad.

Host OpenVPN split-tunnel on k3s-dev-3 validated 2026-08-24: tun0 up, VPN egress
158.173.241.36, node default unchanged (WAN), scoped nft kill-switch active. Wire the
CiliumEgressGatewayPolicy into the runtime kustomization so egress-class=vpn pods steer
to the node tun0.

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.
