I have tried to check quid's comments containing cast, close, vote, final, binding, fifth - but I did not notice something like this among recent comments.
> However, what I do not like is users objecting to moderators casting votes on principle. This goes too far. I am of the opinion that a moderator that is not willing to ever use the powers they got, is not quite fit for the job, either.

This is a part of his answer to: "What would you do if someone opposes a decision you've made? For example, opposition to removing some comments, closing/reopening/deleting a post, etc. Such opposition may come from direct comments or votes to reopen a question closed by a mod, etc."
Also, "recently" is "since I started interacting with meta", which is now about 2 years out, I suppose.
And, again, my recollection may simply be flawed. I could have sworn that quid expressed some hesitance to cast a preemptive close vote, and that he would prefer to let the community figure things out.
Thanks Martin for putting in so much effort to explain your construction - it's very intuitive! I was thinking whether you can just copy it to the other question? — Dominic van der Zypen6 hours ago
Maybe the easiest thing is to put a comment in the original quesiton, pointing to your answer of this question, which also answers the oritinal one. — Dominic van der Zypen29 mins ago
@DominicvanderZypen Now that the question has been edited - so that the newer question contains the stronger variant - I think we could deleted the above comments, they are no longer relevant.
I have already deleted my comment - if you agree with this assessment, you might deleted your two comments.
BTW YCor's suggestion seems reasonable to me:
@DominicvanderZypen I've copied the question here to the other thread. I suggest you delete this one since it doesn't need to be in 2 threads. (For memory, the question was initially downvoted and closed because the sum was not specified to be from $-N$ to $+N$, so the convergence was obviously impossible). — YCor18 mins ago
