Yeah, I tried. Just caused different issues. Pushed next attempt just now.

So now only one issue remains:

1 blank line required before class docstring (found 0) (D203)

Are you sure about that one? There is literally not a single class in your code that fullfills this. All the existing ones that actually have class comments have them directly after the class statement. Wouldn't it be better to disable D203 and use D211 ("No blank lines allowed before class docstring") instead?
