I am trying to understand how custom expressions are represented internally in Metabase. When reviewing the dataset_query field in the application database, I can see MBQL structures, but I am having difficulty understanding how those MBQL expressions correspond to the expressions shown in the Query Builder UI (for example, Custom Column expressions). Is there any documentation, schema reference, or developer guide that explains: The structure and syntax of MBQL expressions How MBQL maps to expr
