  "$comment": "`components` embeds an object of this module, and its terms are kept apart by the scope the composition term carries in Material.schema.json. Scoping Composition here as well would layer the base's plain `constituent` over this schema's own and lose both its coercion and its mapping, so OOLD-CMP-5266 is answered one level up.",
