Goal: We would like to apply manufactured stone to
the exposed portion (above grade and below siding–about 16 inches) of
poured basement wall.
Current situation: the mudsills were installed flush to the outside of
the poured wall and there is 1/2 inch sheathing on the house. Beveled
cedar siding (about 1/2 inch thick) will be applied to the sheathing.
This will create about a one-inch projection beyond the poured basement
wall.
The Question: How should I make the transition from the wood
to the manufactured wall? Is there a good way to do this with flashing, or would this
just be inviting water problems? For aesthetic reasons, I do not want
to use manufactured stone sills.

good question, I was wondering about that recently too.
Couldn't the top of the stone be beveled mortar to shed water?
The bevel would also help to reduce the appearance that the stone would stick out beyond the wood above it.
To help prevent the water falling directly on that bevel from soaking in and freeze-spalling it off the wall, how about a zee flashing stuck under the wood that lays on the bevel and has a drip lip just beyond the end of the bevel (if done in copper it could really accent the transition from wood to stone nicely).
If you want to get real fancy, you would put an angled piece of wood siding to shed water away from the stone below, what do they call that when the 'water table' moulding (horizontal styling detail between the foundation below and the wood wall above) is shaped to shed water? I forgot the term. Lots of old houses were built this way to help direct some water away from the stone foundation.

I don't know the proper term for it either, but I sometimes, when given the option, install a beveled skirt around the bottom of walls before installing beveled siding or cement board. I usually make it up myself (rip 2X material to whatever reveal looks good or is most functional, at about a 12 degree angle where it meets the sheathing). I use a treated deck material (non-incized), prime and back-prime and it looks good and serves to direct water away from the foundation or mud from splashing up from the flower beds.Measure it with a micrometer, mark it with a piece of chalk and cut it with an axe.
