Yes. My understanding is that you get the moisture down to a certain
level then keep it there. If it fluctuates a little bit, no problem.
Even plaster breathes a little bit.  The key is that the internal
humidity never goes above a certain percentage.

I've never built a cob or straw bale house. Is this correct?
