My 2 cents:
1. The current "handshake" terms have a serious problem, in
distributed systems research "N-way handshake" is used in protocols
between N parties. So 4-way handshake would suggest 4 parties are
involved.
2. Retrieval is a great term. Single step retrieval and 2-step
retrieval (or something similar) are fine.
3. Get is even better, because it's shorter. Single (or 1-step) get
and 2-step get: fine.
4. Partial get may be better again, because even though it's longer
it's a better fit to what we're actually doing. For now, this one has
my vote.
