The 10Gi proxmox-lvm-encrypted PVC `claude-agent-workspace-encrypted` was
declared in TF but never wired into the deployment — the `workspace`
volume_mount pointed at an emptyDir, so the PVC sat allocated and idle
from 2026-04-15 to 2026-05-11.
Restructured per the design intent:
* `workspace` (emptyDir) — fast per-pod ephemeral scratch for git clones.
Each agent job clones the infra repo fresh, so persistence doesn't
buy anything and emptyDir avoids RWO contention if the deployment
is ever scaled past 1 replica.
* `persistent` (5Gi NFS-backed RWX) — mounted at /persistent for cases
where the agent needs to write state that should survive pod
restarts (caches, ad-hoc outputs). RWX so all replicas share it;
the service's sequential-mutex lock prevents concurrent writes.
Also fixed `fix-perms` init container: the Dockerfile's `WORKDIR
/workspace/infra` causes kubelet to create that path inside the
emptyDir as root:fsGroup with the setgid bit, which uid 1000 can't
write to. Pre-create the path + chmod 0775 to make it writable.
NFS export already exists on the PVE host
(/srv/nfs/claude-agent-persistent, owned 1000:1000).
Verified: pod runs 1/1; `/persistent` writable as agent uid 1000;
git-init successfully clones infra into /workspace/infra.
