Struct EntityPreimage 

pub struct EntityPreimage {
    pub name: Option<String>,
    pub description: Option<Option<String>>,
    pub properties: Option<BTreeMap<String, PropertyValue>>,
    pub tags: Option<Vec<String>>,
}

Prior value of exactly the fields an UpdateOp’s patch touches, captured at stage time. Mirrors EntityPatch’s field shape one-to-one: a populated preimage field means “the patch touches this field, and this was its value before the patch”; an absent preimage field means “the patch leaves this field unchanged.” UpdateOp’s custom Deserialize enforces that this field set exactly equals EntityPatch’s touched-field set.
