Handler notes
Darkages.exe:0x00443B10 ui_spell_inventory_handle_server_packet routes this action to the spell-slot removal path. That path unregisters and removes the child, deletes it, and clears the indexed owner pointer. Darkages.exe:0x004889F0 also observes the action in its own pane context.
UI behavior
Removing a slot does not hide the parent spell inventory. See UI, Input, and Packet Flows.
