6d224861 came from a --no-checkout worktree whose empty index made the
commit drop every file except two. This restores 05b50d2b's full tree and
correctly adds stacks/stem95su/gdrive-sync.tf + the service-catalog stem95su
entry. Forward-only (parent=6d224861, no force-push); [ci skip] since the
live infra was never applied from the broken commit.

CronJob stem95su-gdrive-sync (*/10) mounts the content PVC RW and
rclone-syncs the read-only Drive folder "claude" (stem claude/files) onto
it (rclone/rclone:1.74.3, scope=drive.readonly, empty-source guard +
--max-delete 25). ESO ExternalSecret stem95su-rclone <- Vault
secret/stem95su. Requires the GCP OAuth app published to Production or the
refresh token expires ~weekly.
Lands the gdrive-sync stack on master (it had landed on a feature branch
by accident on the shared devvm checkout).

Adds a weekly detection CronJob (Sun 12:00 UTC) that probes apt-cache madison
on master for new patches + HEAD pkgs.k8s.io for next-minor availability,
then POSTs to claude-agent-service to dispatch the k8s-version-upgrade agent.
The agent (.claude/agents/k8s-version-upgrade.md) orchestrates:
pre-flight (5 nodes Ready + halt-on-alert + 24h-quiet + plan target match)
-> etcd snapshot save
-> optional master containerd skew fix
-> apt repo URL rewrite (minor bumps only)
-> drain/upgrade/uncordon master via ssh < update_k8s.sh
-> sequential workers k8s-node4 -> 3 -> 2 -> 1 with 10-min soak each
-> post-flight verification
Two new Upgrade Gates alerts catch failure modes:
- K8sVersionSkew (kubelet/apiserver gitVersion mismatch >30m)
- EtcdPreUpgradeSnapshotMissing (in_flight without snapshot_taken >10m)
update_k8s.sh refactored to take --role / --release args; the agent shells
it into each node via SSH pipe. update_node.sh annotated as OS-major path.
Operator-facing docs: docs/runbooks/k8s-version-upgrade.md and a new section
in docs/architecture/automated-upgrades.md.
Secrets: secret/k8s-upgrade/{ssh_key,ssh_key_pub,slack_webhook} (ed25519
keypair distributed to all 5 nodes via authorized_keys; slack_webhook
reuses kured webhook URL on initial deploy).
