Based on the available knowledge sources, there is no official support or documentation indicating that Elementary works with SQLMesh. In fact, the knowledge sources do not mention SQLMesh compatibility or any official workaround for using Elementary with SQLMesh. The only supported workflow described is with dbt. If you have seen external documentation or discussions about SQLMesh implementing a workaround to ignore Elementary models, that information is not present in the provided knowledge sources. Therefore, I cannot confirm or elaborate on SQLMesh compatibility with Elementary based on the current documentation and support channels for Elementary.
