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).

The agent-based v1 ran inside claude-agent-service (replicas=1, no
nodeSelector) and self-evicted when it tried to drain its host (k8s-node4
on 2026-05-11). Cluster ended half-upgraded (master v1.34.7, workers
v1.34.2) until manual recovery.
Rewrite the pipeline as a chain of nodeSelector-pinned Jobs:
preflight (k8s-node1)
→ master (k8s-node1) drains k8s-master
→ worker × 4 (k8s-node1) drains k8s-node{4,3,2}
→ worker (k8s-master + control-plane toleration) drains k8s-node1
→ postflight (no pinning)
Each Job runs scripts/upgrade-step.sh (case-on-$PHASE) and ends by
envsubst-ing job-template.yaml into the next Job. Deterministic names
(k8s-upgrade-<phase>-<target_version>[-<node>]) make `kubectl apply`
idempotent — a failed Job can be re-created without duplicating
downstream.
Also lands `predrain_unstick`: deletes pods on the target node whose PDB
has 0 disruptionsAllowed. Without this, drain loops indefinitely on
single-replica deployments (e.g. every Anubis instance — discovered the
hard way during 2026-05-11 manual recovery of k8s-node3).
Adds K8sUpgradeStalled alert (in_flight + started_timestamp > 90 min).
Deprecates the agent prompt (renamed to *.deprecated.md with a header
pointer to the new code).
Apply order: k8s-version-upgrade first (consumes new SA + ConfigMaps),
then monitoring (loads the new alert). Both applied 2026-05-11.
