+"""lvx-purge-orphans — remove deprecated HA-discovery entities from MQTT.
+
+After the powermon-patches (g) cleanup + GS excl_filter additions:
+  - several fields are no longer published (always-zero / dead on this hardware)
+  - one entity got renamed (dc-ac_power_direction → dc_ac_power_direction)
+
+This tool publishes empty retained payloads to those orphan config topics so
+HA forgets the entities cleanly.
+
+Idempotent. Compatible with paho-mqtt 1.x and 2.x.
+
+Usage:
+    lvx-purge-orphans <broker> <user> <password> [--dry-run]
