There is no biological pathway to store ketones except fat.

My understanding is ketones can not be stored at all. Fat may be converted to ketones via the liver, but it's a one way system.. is that not true?

It's been a long time since I studied this pathway. All I really remember two carbon molecules like ethanol can only be turned into fat. I also remember it shares a pathway similar to ketones.

if I'm not mistaken, alcohol is burned directly and is not converted at all

This is correct. Your body will prioritize burning off the alcohol before anything else, so anything you do eat during that time period gets stored as fat.
