- Restore 0x02→0x80 Classic harmful-to-WotLK debuff bit mapping in syncClassicAurasFromFields so downstream checks work across expansions - Extract handleDisplayIdChange helper to deduplicate identical logic in onValuesUpdateUnit and onValuesUpdatePlayer - Remove unused newItemCreated parameter from handleValuesUpdate - Fix indentation on PLAYER_DEAD/PLAYER_ALIVE/PLAYER_UNGHOST emit calls
