+# PURPOSE
+# ─────────────────────────────────────────────────────────────────────────────
+# Maintains the persistent partner conf backup at /boot/config/.cache/vv/d/.
+# Runs every minute via SYSTEM_WATCHDOG_SCRIPTS.
+#
+# When remote is OFFLINE:
+#   Writes/refreshes partner confs from RAM cache → persistent location.
+#   Means if this host reboots while remote is still down, conf_cache_restore.sh
+#   can load the partner vars into RAM so fallback.sh has what it needs.
+#
+# When remote is ONLINE:
+#   Removes the persistent backup if present — not needed, conf_sync.sh will
+#   pull fresh on next boot.
+#
+# Silent when remote is online and no backup exists (normal state).
+# No-op when FALLBACK_ENABLED=false or CONF_SYNC_ENABLED=false.
