Iterate the entity set visible in this session. The source index is never
mutated. Callers expand schema subtypes before passing types (matched
case-insensitively against the exact class). sourceIds restricts source
records to a caller's existing domain (an EntityTable's rows, say) while
still appending overlay creations. It avoids scanning unrelated STEP records.
