i think for the recycling of premade maps, we just have to embed the dungeon graph in the map files. Unexplored had extra rules to first draw out the shape of a dungeon and then add different walk/crawl spaces before going on to populate. In this case, we just don't do the shape grammar to draw out the space at first.

We do still have graph replacement that looks at the number of edges and such, but the map pre-specifies the original symbols to get changed out.

so that part isn't so hard to reason about i suppose :cirno_think:

this method does require trenchbrooming up handfuls of dungeon layouts and then tying together the room IDs and all that shit, but it does mean some variance in the actual encounters found there still exist.
