Ok, thats what i thought. But just for implementation ideas, how does
CoreData know when one of it's @dynamic properties is changed? It must
set some sort of flag somewhere in order to know what to write out
when it needs to save. How does it handle that?
thx

No, not in general. Key-value observing requires knowing the exact
property name(s) in advance. You'll need to set the 'dirty' flag
manually.
