compress Merkle DAG and origin nodes together
Closed, ResolvedPublic

Description

We've created a compressed representation of the archive Merkle DAG, from snapshot nodes down to contents.
Strictly speaking that is exhaustive, but for some use cases (e.g., list all the different origins where a given node has been found) it would be useful to also have nodes representing origins.
Now that we know compressing the full Merkle DAG is doable, we should give a try to the extended version that also includes origin nodes. It shouldn't be much harder, given the added nodes/edges are not that numerous.
