Would the term "pruned_leaf" be an acceptable compromise?  The
"pruned_" prefix would imply the "context" you mentioned above as well
as "subset of them" [where them is nodes] mengioned above.  In the
case that the node was an actual leaf (e.g. an actual file) then the
"size of the pruning" would be just 0, where "size of pruning" is the
distance to an actual leaf (where actual leaf means the same as leaf
node in this quote:

).
