Thanks Joel & Andres for making the question much clearer & better!

Completion of a single totally ordered down-set
Hang on - $t$ and $\{x\}\cup t$ are comparable, so $B$ is no longer a bunch, isn't it...? (Thanks to Joel Adler for noticing this.)

Sum-epimorphisms and prod-monomorphisms
So for the latter question about "direct product decomposition" you assume that $Y\cong A\times B$ if I understand correctly?

Lovely problem! I will think first about the (possibly trivial and uninteresting) variant $\Delta(G)=1$ and $|V_i|=2$.

Oh - thanks. Can you put this as an answer so we can close the question?

Complete sets of incompatible totally ordered down-set in a partially ordered set
I suggest "bunch" and have used this in a follow-up question, see mathoverflow.net/questions/198820/…

That's right - this is much more concise...! Thanks for this example.
