When I saw the previous submission of this as https://news.ycombinator.com/item?id=18853508 (which describes it as a "tool-assisted speedrun" of NetHack on the online server nethack.alt.org), I thought "wait, you can't have a tool-assisted speedrun of a nondeterministic game with hidden information...!" (particularly on an online server where you can't roll back history).
Then I read the article and saw that this project went to absolutely insane lengths to work around the "nondeterministic" and "hidden information" parts.
