just a super minor comment: in memory-infra context we use the term
"effective_size" to refer to (memory - aliasing) (see the various
AddOwnershipEdge). Using the same name here might generate a bit of confusion.
Can this be named just size, or real_size, used_size or whatever !=
effective_size? :)

Done.
