You have the trunk defined by the headers. Once a range from genesis to =
block n is fully downloaded,
you may validate upto block n. Furthermore after validation you can =
prune transactions spent until block n.
You would approach the highest block with validation and stop pruning =
say 100 blocks before it, to leave room for reorgs.
