> The way stage IDs are generated is that parent stages actually have higher stage id. This is very confusing because parent stages get scheduled & executed first.
> We should reverse that order so the scheduling timeline of stages (absent of failures) is monotonic, i.e. stages that are executed first have lower stage ids.
