whoaaaaa, the original STAR-L0 was essentially like n0's bao/chunk group=2; STAR-L1 like chunk-group=4 (structurally) (bao is lucky that the number of children in the tree is fixed and chunk sizes are fixed though) outboard proofs are neat and could be interesting for MSTs next to STAR archives 👀

(cool thing about the new generic soon-actually-standard STAR format is we can do an L0-like (or even classic preordered-atproto-CAR-like) archive format inside it and keep playing around here)

W/o chunk groups, you're filling the buffer up only up to 1024 plus a bunch of layers from the Merkle proof relative to the root. W/ chunk groups you fill it up to 16KiB plus the proof. But on the proof level you could again transmit a set of say 64 chunk group hashes at once and derive parents

ohh yeah neat. saving transmitting like ~half the hashes in bao?
