Maybe I'm missing something, but if the array is initialized to all zeroes, it seems to be outputting zeroes forever.

Fair enough, you also wrote:

However, how can we be sure that the array never turns into (and gets stuck in) an all-zero state?

I.e. which initialization values should be avoided or specifically chosen?

And how do the changes your proposed in later emails affect this? (I did not see any changes that avoid the all-zeroes 
issue, but may have overlooked them).

P.S. I specifically signed up for this list to write this mail, so it will probably be shown out of thread order.
I'm not a cryptographer, but interested (I've been reading https://www.metzdowd.com/pipermail/cryptography/ for a long 
time). Googling ["Erik van Straten" security] (without []) provides some info on me (I'm not on LinkedIn).
