ObjectReference for Equipped Items

[HomoPuerRobustus]

I am trying to get the ObjectReference of an equipped weapon, and I have a question about how the game system handles improved or player-enchanted items. I understand that most objects in a container (like the player's inventory or equipped on the player) do not have stable ObjectReferences. It seems there must be something persistent, however, because tempered weapons and weapons with enchantments created by the player have stable qualities, and given that GetItemHealthPercentage() and GetEnchantment() are members of the SKSE ObjectReference Script, it makes sense that they are stored as ObjectReferences. If I can't access the ObjectReference of a generic item, does anyone know how to access the ObjectReference of a quasi-unique item?
