 ### Removed
 - **democratic-csi**: `democratic_csi_*` variables, the `deploy_democratic_csi_{nprd,prd,poc}_apps` resources (never in state; count was 0), the `democratic_csi_config` output, `scripts/install-democratic-csi.sh`, `scripts/generate-helm-values-from-tfvars.sh` and `docs/DEMOCRATIC_CSI_TRUENAS_SETUP.md`. Nothing on any cluster used the driver; TrueNAS CSI is the only storage driver. Remove the `democratic_csi_*` entries from your local `terraform.tfvars`
+- **democratic-csi** `democratic_csi_config` output dropped from Terraform state (state edit only, no apply; resources unchanged). Remaining TrueNAS-side cleanup is listed in [docs/TRUENAS_CSI_MIGRATION.md](docs/TRUENAS_CSI_MIGRATION.md#truenas-manual)

 ## Cleanup After Migration
 
-When no PVCs use `truenas-nfs`:
+Kubernetes and Terraform cleanup is complete (2026-10-04): no democratic-csi namespace, Helm release, CSIDriver, StorageClass, PV/PVC, CRD, RBAC or Fleet bundle on any cluster, and the stale `democratic_csi_config` output was removed from Terraform state.
 
-1. Verify:
-   ```bash
-   kubectl get pv -o json | jq -r '.items[] | select(.spec.storageClassName=="truenas-nfs") | .metadata.name'
-   # Should return nothing

+### TrueNAS (manual)
+
+democratic-csi used the `freenas-api-nfs` driver against `192.168.9.10`. TrueNAS CSI creates its volumes directly under the pool (`SAS/pvc-*`), so nothing below is used by it:
 
-2. Set `install_democratic_csi = false` in terraform.tfvars.
+| Object | What to do |
+|--------|------------|
+| Dataset `SAS/RKE2` and children `SAS/RKE2/pvc-*` (e.g. `pvc-25d4289c-38a0-4c20-96ef-35d2cd91356d`, the old nprd Loki ingester) | Check nothing you want is left, then delete recursively |
+| Dataset `SAS/RKE2-snapshots` (detached snapshots parent), if present | Delete |
+| NFS shares with paths under `/mnt/SAS/RKE2/` | Delete (before the datasets) |
+| democratic-csi API key (was `democratic_csi_api_key`, user `rke2`) | Revoke. TrueNAS CSI uses its own key (`truenas_csi_api_key` → secret `truenas-api-credentials`) |
 
-3. Run `terraform apply` to remove Democratic CSI.
+Before revoking, confirm in **Credentials → API Keys** that the key's last-used time is not recent. If the same key value was ever pasted into `truenas_csi_api_key`, revoking it would break TrueNAS CSI on all app clusters.
