You don’t actually want that.

Code should not inform design.

Design informs code.

Use the code to do the design. Don’t implement the damn thing. Just work in a nicer medium like Typescript. Add attributes. Remove attributes. Move things around in the refactoring tool. Then generate the doc. Forget about the whole “this is what the database does” stuff.
