+# Applied to worker.yaml alongside patch-longhorn.yaml. These two workers are
+# amd64 Proxmox VMs; they run ordinary application Pods and provide Longhorn's
+# two independent storage replicas.
+#
+# `disk: /dev/sda` is the dedicated 20GiB Talos boot disk. Longhorn's 350GiB
+# disk is /dev/sdb and is selected separately by patch-longhorn.yaml. Naming
+# both roles explicitly prevents an installer or storage selector from
+# claiming the wrong virtual disk.
+#
+# The custom Image Factory installer contains Longhorn's `iscsi-tools` and
+# `util-linux-tools` extensions plus `qemu-guest-agent`. Keep this schematic
+# reference during future upgrades; switching to the stock installer would
+# silently remove those extensions.
+#
+# Both VMs use `ens18`. Their DHCP-reserved MAC addresses keep worker01 at
+# 10.10.10.203 and worker02 at 10.10.10.204 while DHCP supplies their gateway
+# and DNS settings.
