Enum Edit 

pub enum Edit {
    Create {
        id: EntityId,
        entity: Entity,
    },
    SetAttribute {
        id: EntityId,
        slot: usize,
        value: Value,
    },
    Retype {
        id: EntityId,
        type_name: Arc<str>,
    },
    Remove {
        id: EntityId,
    },
}

One staged change.

Deliberately structural: there is no set_name or set_material here. Domain-shaped authoring belongs in the crate that owns the domain, built on top of these operations – otherwise every schema concept leaks into the model layer, which is the boundary this crate exists to hold.
