Adds apps/monitoring/prometheus-deployment.yaml capturing the live PVC/Service/
Deployment for monitoring/prometheus. Two behaviour changes vs the previous
live state:
- strategy: RollingUpdate -> Recreate. prometheus-data-encrypted is RWO on
hcloud-volumes-encrypted; a rolling update deadlocks because the surge pod
cannot attach the PVC while the old pod holds it. This has been jamming the
weekly OS-update preflight (see DEV-582). Same fix pattern as loki
(loki-deployment.yaml) and opencloud (DEV-538).
- pod-template annotation backup.velero.io/backup-volumes-excludes:
prometheus-storage. Restores the annotation that rev 6 tried to add before
the RollingUpdate deadlock forced a rollback in DEV-582.
Applied and verified: rollout succeeded, /-/ready and /-/healthy both green,
pod running on k3s-worker-6 after PVC re-attach.

Velero cluster-all now covers cluster-manifest backup with two successive
Completed runs verified and one restore drill (openwebui) green (DEV-575).

- CronJob at 0 4 1 * * restores the latest openwebui-manifests backup into
a transient restore-test-<ts> namespace, diffs core resource-kind counts
against the live openwebui namespace, and deletes the target namespace.
- ServiceAccount + ClusterRole scoped to velero.io + namespace + configmap
ops. Script enforces the 'restore-test-' name prefix before deleting a
namespace. Cluster-wide 'view' bound for the diff.
- Failure surfaces via kube_job_status_failed (DEV-574 alert stack) and via
ConfigMap velero-restore-drill-last-result written on every run.
- Optional Paperclip webhook Secret is sealed but unreachable from Hetzner
right now (home Paperclip is LAN-only); wired as optional secretKeyRef so
the drill runs regardless. Connectivity is a follow-up.
- Argo Application velero-restore-drill points at velero/restore-drill/.

Adds Prometheus scrape of Velero's :8085 metrics and four alerts
(VeleroBackupFailed, VeleroBackupPartial, VeleroBackupMissed,
VeleroStorageLocationUnavailable) labeled team=infra severity=warning.
VeleroStorageLocationUnavailable substitutes for the spec's
VeleroRepoUnhealthy since Velero v1.18.1 does not expose
velero_backup_repository_available (see comment in the rule).
Wired via a new ArgoCD Application (velero-monitoring) that syncs
only servicemonitor.yaml + prometheusrule.yaml from basicstack-repo/velero/.

- velero/schedules/: cluster-all @ 03:00 (30d TTL, manifests only),
per-namespace <ns>-manifests @ 03:15+n min (30 in-scope namespaces,
30d TTL, no fs backup), and per-namespace <ns>-data @ 03:45+n min
for the whitelist (pocket-id, vaultwarden, vikunja, passbolt;
14d TTL, defaultVolumesToFsBackup=true).
- All schedules exclude velero, kube-system, kube-node-lease,
kube-public so the Kopia password Secret never lands in S3.
- apps/app-velero-schedules.yaml: sibling Argo app syncing that
directory into namespace velero with prune+selfHeal.
- opencloud, harbor(registry+trivy): pod-template annotation
backup.velero.io/backup-volumes-excludes as a safety net so blob-
heavy PVCs are never fs-backed-up even under a manual defaultVolumes
run. nextcloud/monitoring workloads are not Argo-tracked yet — they
were patched live in the same commit but need a follow-up to source-
control them.

The prior sealed secret's access key lived in the personal `imicros.de`
Hetzner Object Storage project and could not list objects in
`basicstack-velero` (bucket is in the BasicStack project) — BSL was
`Unavailable` with an S3 `AccessDenied` on ListObjectsV2.
CEO created a new S3 credential in the BasicStack project; re-sealed
against the cluster controller and applied. BSL `default` now
`Available`.

- velero-plugin-for-aws v1.14.3 is not published on docker.io (only rc.1/rc.2). Downgrade to the latest GA tag v1.14.2 — still compatible with Velero 1.18.x.
- Drop node-agent memory request 256Mi -> 64Mi so the daemonset schedules on worker-1/2/3 (they sit at ~95% memory-request already).

Adds SealedSecret velero-s3-credentials in namespace velero, holding
the dedicated velero-prod Hetzner Object Storage access/secret key
(scoped only to the basicstack-velero bucket).
Sealed on cp-1 via /root/seal-velero-s3-credentials.sh with the
sealed-secrets-controller public cert; plaintext never left the host.
Only the in-cluster controller can decrypt.

Adds the Open WebUI stack at openwebui.basicstack.de:
- Namespace `openwebui`, ArgoCD Application with auto-sync + selfHeal
- Own Postgres 16 + pgvector (`pgvector/pgvector:pg16`, 20Gi encrypted PVC,
fsn1-pinned); VECTOR_DB=pgvector, extension auto-created
- Own Redis 7 (2Gi encrypted PVC, fsn1-pinned) used both as cache and as
websocket manager (db=1)
- Hetzner Object Storage bucket `openwebui-basicstack` (hel1, path-style)
for file uploads; shared project S3 credentials
- Traefik ingress + Let's Encrypt TLS
- Pocket ID client `Open WebUI` (PKCE on) restricted to groups
`openwebui_admins` and `openwebui_users`; `andreas.leinen@basicstack.de`
is member of both and gets admin via OAUTH_ADMIN_ROLES
- Password login disabled (`ENABLE_LOGIN_FORM=false`, `ENABLE_SIGNUP=false`)

Stalwart's port-25 relay rejects bare EHLO labels — needs at least one
dot. Vikunja doesn't call go-mail's WithHELO, so it sends
os.Hostname() as EHLO. Setting hostname/subdomain plus
setHostnameAsFQDN=true makes the pod's kernel hostname a valid FQDN
(vikunja.basicstack.vikunja.svc.cluster.local), which Stalwart
accepts.
Co-Authored-By: Paperclip <noreply@paperclip.ing>
Vikunja now sends reminder/notification emails through
`stalwart-smtp.stalwart.svc.cluster.local:25` using unauthenticated
relay from the pod-network CIDR that Stalwart already trusts. The
`vikunja@basicstack.de` principal exists in Stalwart but its password
is unknown and admin API access to reset it is currently broken
(admin/andreas/paperclip password auth returns `{"type":"failure"}` per
`stalwart-oidc-only-admin` note). Verified end-to-end: message from
`vikunja@basicstack.de` sent via port-25 relay arrived in the passbolt
mailbox.

Adds the kaneo-smtp SealedSecret and points the Kaneo container at
mail.basicstack.de:587 (STARTTLS) for outbound workspace invites and
notifications. DISABLE_EMAIL_OTP_SIGN_IN stays true so sign-in remains
OIDC-only via Pocket ID.

Outline's OIDC plugin does not send `code_challenge`, so the Pocket ID
client must be created with `pkceEnabled: false` (default is `true`).
Login fails with `?notice=auth-error` and Pocket ID rejects
`/authorize` when PKCE is enforced.
Co-Authored-By: Paperclip <noreply@paperclip.ing>
Vikunja 2.x's frontend redirect helper and Go backend do not send
code_challenge. Pocket ID rejects the /authorize call with
'code_challenge parameter is missing' when the client has pkceEnabled=true.
The Vikunja client is confidential (isPublic=false) so client_secret still
authenticates the token exchange — turning PKCE off is safe and required.
Co-Authored-By: Paperclip <noreply@paperclip.ing>
Add `vikunja_scope` to the OIDC scope list the Vikunja app requests
from Pocket ID, so the `vikunja_groups` custom claim is available for
Vikunja's automatic team provisioning.
The claim itself is set per Pocket ID user group (`vikunja_admins`,
`vikunja_members`) via `PUT /api/custom-claims/user-group/:id`.

Namespace-scoped Postgres 16 + unified Vikunja container behind Traefik
ingress at vikunja.basicstack.de. Both pods pinned to Hetzner fsn1 due to

- Traefik ingress at kaneo.basicstack.de with letsencrypt-prod cert.
- Better Auth JWT secret and Postgres credentials as SealedSecrets.
- OIDC via Pocket ID using CUSTOM_OAUTH_*, restricted to the two
new Pocket ID groups kaneo-admins / kaneo-members (client id
d58ff9bb-dc98-49b4-9535-4af2aba66de2).

The scheduled backup pod could not start because worker-3 (where the
opencloud data PVC is attached and where podAffinity pins the backup)
had ~40Mi of memory left by requests after opencloud/tika were
co-scheduled. rclone actually uses well under 100Mi during the sync.
Drop cpu request 100m -> 50m and memory request 256Mi -> 64Mi. Limits
unchanged (500m / 512Mi) so it can still burst.

The 7.2.0 -> 7.4.0 rollout stalled because the default RollingUpdate
tried to start the new pod before terminating the old one, but they
both mount opencloud-data (RWO), causing Multi-Attach errors.
Switch to strategy: Recreate so the old pod is terminated first and
the volume detaches cleanly before the new pod starts. Same fix
pattern as bookstack (DEV-528) and other RWO-backed apps.

The Job self-deletes after ttlSecondsAfterFinished=3600, causing ArgoCD
to report the app permanently OutOfSync. The job body only hits
/healthz/live and prints a manual TODO; it never modified Stalwart
config. The real IP allowlist is already declared in
apps/stalwart/stalwart-config.yaml under
[server.listener.*.security] allowed-ips.
Also removes the orphan ServiceAccount/Role/RoleBinding
stalwart-config-access bundled in the same file.

BookStack is a single-replica Deployment backed by a ReadWriteOnce
PVC (`bookstack-config`). The default RollingUpdate strategy creates
the new pod before terminating the old one, and the two pods cannot
share the RWO volume — so every rollout deadlocks on
`Multi-Attach error for volume`.
Switching to `strategy: Recreate` terminates the old pod first,
releases the PVC, and then starts the new pod. Brief downtime is
expected on rollout, but rollouts actually complete.
Discovered while rolling out the `/status` probe fix (previous commit).
Co-Authored-By: Paperclip <noreply@paperclip.ing>
BookStack's `/` returns 302 → /login, which caused Kubernetes to
raise ProbeWarning events on the readiness (and liveness) probes.
`/status` is BookStack's built-in monitoring endpoint: it returns
200 without a redirect and is designed for health checks.

Argo CD only substitutes $secret:key references from Secrets carrying
the label app.kubernetes.io/part-of: argocd. Without it, the server
logs "secret key does not exist in secret" and renders placeholders
verbatim into the OIDC redirect URL.
Adding the label to the SealedSecret template ensures sealed-secrets-
controller re-produces the Secret with the label on every restore, so
OIDC keeps working after DR / re-seal.

Post-migration verify uncovered that Pocket ID OIDC login was broken:
the argocd-server was rendering $oidc.pocketid.clientId literally into
the authorize URL instead of substituting the client id.
The Helm chart's default $key syntax looks in argocd-secret, but our
OIDC keys are held only in the SealedSecret-backed argocd-oidc-secret
Opaque secret. Pre-migration argocd-secret happened to contain byte-for-
byte copies of those keys (legacy install), which is why it worked.
Switch to Argo CD's $secret:key form so the values point at the correct
secret without duplicating sealed material into argocd-secret.

Argo CD server was returning HTTP 307 redirect loop behind Traefik

Argo CD repo-server needs the forgejo.forgejo.svc.cluster.local host key
in its known_hosts to clone the git repos over SSH. Adding it to
configs.ssh.extraHosts so the helm-managed ssh-known-hosts-cm renders
the entry from git and does not drift when the argocd Application syncs.

Replace the vendored ~33k-line apps/argocd/argocd-install.yaml with the
argoproj/argo-helm chart argo-cd 10.4.0 (app v3.5.1). Values live in
apps/argocd/values.yaml; the local kustomize wrapper now only carries the
Traefik ingress and the sealed secrets. The root apps/app-argocd.yaml
Application becomes multi-source (chart + this repo as $values), enables
ServerSideApply + ApplyOutOfSyncOnly, and pins the resources-finalizer
explicitly.
Behavior-equivalent to the previous install: same URL, OIDC (Pocket ID),
argo_admins RBAC mapping, resource.exclusions list, and per-component
memory limits (DEV-281). Ingress is disabled in the chart; ours stays in
kustomize with cert-manager letsencrypt-prod annotations.
README.md updated with the Helm bump procedure. argocd-install.yaml
removed.
Verified locally:
helm template argocd argo/argo-cd --version 10.4.0 \
-f apps/argocd/values.yaml -n argocd
# renders 34k lines, image: quay.io/argoproj/argocd:v3.5.1

Rolling OS updates removed docker.io from all workers, breaking the
runner's hostPath mount of /var/run/docker.sock (type=Socket check).
- Install docker.io on all 5 worker nodes and enable the systemd unit.
- Label the nodes basicstack.de/docker=true so the dependency is explicit.
- Add nodeSelector to the Deployment so scheduling fails fast on
non-labeled nodes instead of hanging in ContainerCreating.
- Document the node prerequisite in the README.

Migrates the last plaintext-at-rest monitoring backup off rclone-sync
onto the same restic pipeline as loki/grafana/k8s-resources. Closes
the Hetzner Object Storage gap flagged in DEV-482 — no SSE-S3/SSE-KMS
means every object we push must be encrypted client-side.
- apps/monitoring/prometheus-backup-cronjob.yaml: pin the image to the
Harbor mirror `harbor.basicstack.de/library/restic:0.17.3` (DEV-493)
so the pull path matches the sibling CronJobs.
- docs/monitoring/restic-restore.md: append the DEV-492 drill entry —
cold restic init, 8.017 GiB → 2.441 GiB stored, `restic check`
clean, restore of `latest` into a scratch namespace, then
`promtool tsdb list` + `promtool tsdb analyze` against all 19
blocks (0 failed). Confirms the compaction-race mitigation
(`--exclude wal/*`/`chunks_head/*` + accept exit 3) does not leave
a corrupt snapshot. Also documents the DEV-492 Prometheus repo in
the layout table + per-repo restore commands.
- apps/monitoring/README.md: point the restore section at all four
repos and cite DEV-488 (loki/k8s) + DEV-492 (prometheus) drill
entries.
Definition of done (DEV-492):
- backup ships client-side-encrypted to Hetzner: ✅ (restic init
succeeded on the manual run; snapshot 71420465 written)
- restore drill promtool tsdb analyze clean: ✅ (19/19 blocks OK)
- OBSERVABILITY_BASELINE.md + apps/monitoring/README.md updated: ✅
- restic-password ownership documented: ✅ (README shared-SealedSecret
table already covered all four repos after this change)
