I think Lux-Perpetua is a little busy with other things lately, so I wouldn’t count on updates any time soon. Not sure if the .svg source files are available anywhere, or if it’s only rendered .pdf versions.
In any case, with the increase in diagram complexity for Anduril 2, it might be a good idea to rebuild in something like TikZ for LaTeX. This would probably be more maintainable long-term than the Inkscape svg methods used previously. It’d also be good to split it into a series of diagrams for tutorial purposes, and TikZ would make it much easier to keep those in sync with a master reference sheet.
