Actually...
I didn't pay a lot of attention when reporting that: I just deleted all aliases from my db to fix the problem, and the fortune was the obvious breakage.
But looking at the code now, it looks broken in another way: Fish alias output doesn't include a = sign, so it would just be e.g.:

alias emacs 'TERM=xterm-24bits emacs -nw --foo=bar'
alias k kubectl

(Fish allows setting them both ways though: both alias k=kubectl and alias k kubectl work)

Ah I see! Well that needed fixing anyway, glad it's done.

#1972 should sort that

Urgh, it's still sometimes broken now: some ASCII art contains =...
I guess maybe it could redirect the alias output to a file and read that? But that seems like a lot of effort 😞

I don't really mind having to turn off the script for the initial import, and I (only just) figured out I can just atuin dotfiles alias delete those stray "aliases", instead of messing with the database.
