I do think it should be possible to download a "source tarball" that allows easily reproducing the output of our bots on similar host configurations, but I don't think we're quite there yet. It's an AI on our end, for sure. I asked around what people were doing, and it involved basically replicating the bot build by hand using a ton of tribal knowledge and manual editing; it's not something that I could export any easier than it would be to creating a better way to do this.
