I thought this was something like a FUSE driver that would on-the-fly generate any file you tried to read, with some consistency. Like if you open stories/zombie-party.txt it will have some generative network make it, and cache it. If you later ask for stories/zombie-party.odt it can just do a conversion.

I vibe-coded a demo of such a thing, with the idea of making game assets like textures/outdoor/wall.jpg etc. You can do it easily enough, but you need to be patient, and not particularly discerning.
