Transport-only patch bump. No auth/OIDC/config changes.
Snapshots (config.json, DB dump, live YAML) attached to DEV-542.
Rollback: git revert; ArgoCD resyncs; PVCs retained.

 Manifests recording the cluster-side monitoring backup CronJobs that were previously applied out-of-band. These files are the authoritative source (`kubectl apply -f apps/monitoring/`). See [DEV-464](/DEV/issues/DEV-464) for the repair context.
 
-- `backup-k8s-resources-cronjob.yaml` — daily dump of cluster-scoped and per-namespace Kubernetes resources, streamed through `restic backup --stdin` to `hetzner-s3:${BUCKET}/restic/k8s-resources`. Uses `serviceAccountName: backup-sa` and no PVC mount (init container `alpine/k8s:1.29.4` writes an emptyDir, main container `restic/restic:0.17.3` reads it on stdin). Rewritten from the local-path tarball per the [DEV-482](/DEV/issues/DEV-482) Option 4 rollout ([DEV-487](/DEV/issues/DEV-487)).
+- `backup-k8s-resources-cronjob.yaml` — daily dump of cluster-scoped and per-namespace Kubernetes resources, streamed through `restic backup --stdin` to `hetzner-s3:${BUCKET}/restic/k8s-resources`. Uses `serviceAccountName: backup-sa` and no PVC mount (init container `alpine/k8s:1.29.4` writes an emptyDir, main container `restic/restic:0.19.1` reads it on stdin). Rewritten from the local-path tarball per the [DEV-482](/DEV/issues/DEV-482) Option 4 rollout ([DEV-487](/DEV/issues/DEV-487)).
 - `backup-loki-restic-cronjob.yaml` — daily restic backup of `loki-storage-encrypted` to `hetzner-s3:${BUCKET}/restic/loki`. Co-schedules with the Loki pod via `podAffinity` (RWO permits additional read-only mounts on the same node). Deployed per the [DEV-482](/DEV/issues/DEV-482) Option 4 rollout ([DEV-485](/DEV/issues/DEV-485)).
 - `backup-grafana-restic-cronjob.yaml` — daily restic backup of `grafana-storage` to `hetzner-s3:${BUCKET}/restic/grafana`. Pinned to `k3s-worker-2` via `nodeSelector` (the local-path PV anchors the grafana pod there already, no `podAffinity` needed). Schedule `15 3 * * *` — offset from the loki run at `03:00`. Deployed per the [DEV-482](/DEV/issues/DEV-482) Option 4 rollout ([DEV-486](/DEV/issues/DEV-486)).
 - `prometheus-backup-cronjob.yaml` + `prometheus-backup-sealed.yaml` — daily restic backup of `prometheus-data-encrypted` to `hetzner-s3:${BUCKET}/restic/prometheus`. Co-schedules with the Prometheus pod via `podAffinity` so the RWO PVC attaches on the same node. Schedule `30 3 * * *` — offset from the loki (03:00) and grafana (03:15) runs. Migrated from the DEV-465 `rclone sync` job to restic client-side encryption per [DEV-492](/DEV/issues/DEV-492) / [DEV-482](/DEV/issues/DEV-482) Option 4. **Compaction-race mitigation:** `--exclude wal/*` + `--exclude chunks_head/*` + accept `restic backup` exit code 3 (source file vanished mid-walk) as a warning, not a failure; restore drill re-runs `promtool tsdb analyze` per block.
