The graph is very similar to a 30040 index, so I'm lost as to why it shouldn't be param. repl. too.
It's like a visual wiki article with the references being nodes on a canvas.
It's cleaner, I think, but nostr:npub1fjqqy4a93z5zsjwsfxqhc2764kvykfdyttvldkkkdera8dr78vhsmmleku would know.
Maybe a 10000 series replaceable is a happy medium.

yup, that's exactly what it is, so its structure is similar, and would also have a tree geometry, but maybe more like a DAG than a tree to account for merging collisions of changes between users (or at least determining their total ordering).
