poimen-graphql is already ClusterIP on 8090 with no Ingress, so it is off the
internet. It had no NetworkPolicy, so every pod in the cluster could reach it.
The only caller is poimen-memory, which forwards its /graphql route to
MEM_GQL_PORT=8090. No other workload references the service.
Allows 8090 from poimen-memory pods only.
Adds the pi coding-agent sandbox's cluster side:
- `k8s/infra/poimen/pi-agent-workspace-pv.yaml` — static hostPath PV + PVC for the sandbox /workspace (Longhorn cannot attach new volumes in this cluster; this gives real persistence and survived a pod delete/recreate test: marker file + 38 KB session.jsonl intact, the session answered from its own history afterwards).
- `k8s/argocd/secrets/pi-sandbox-secrets.enc.yaml` — the sandbox's API-key Secret, SOPS-encrypted (recipient from .sops.yaml, payload only: `encrypted_regex ^(data|stringData)$`), registered in the ksops generator. Round-trip verified against the live Secret.
- `terraform/files/coredns/Corefile` — `rewrite name pi.riotpiao.com ingress-nginx-controller...` so the hostname resolves in-cluster.
Note: the keys currently in that Secret are the ones leaked earlier and must be rotated; re-encrypt with `sops -e -i` after rotating.Reviewed-on: #54
