Sometimes asking a question is the best way to solve it.
1) How do I select amongst the two or more dpelements that satisfy the dependency on the basis of the size slot? [I suspect this is a job for a custom conflict resolver since the dependency resolving rule activates multiple times.]
A little more RTFM and I discovered the defquery/run-query commands. I can now iterate over the list and select the smallest.
2) How can I recurse into dependent elements to sum up their size? [backwards chaining... seems much like the factorial example in JIA.]
Let me see if I can help myself again.
