I guess this is just one of those situations where the message according to agreement of a call ("partner, we are likely to score well in 3♣x") is redundant and so it becomes a question of what the natural generalization of that message is. If it's "partner, I have clubs" then double is clear; if it's "partner, we are likely to score well by defending whatever the opponents try to play" then pass is clear. All I can say about that is that I think partner and I were on the same page about the double, and it sounds like some of the other posters are on that page too (though they may well be influenced by seeing the hand that doubled).
Your agreement, that double of 3
♣ shows clubs, works on this hand. How often do opps make psychic short suit overcalls red v white? Since opener doubled for penalty in a situation in which responder would often be happy to pass with a stiff, just how many clubs will responder hold when the opps aren't psyching?
In my games, I can't remember a red v white player making such a bid....maybe others see it as a common enough occurence that they design their bidding around it...as you seem to.
If the other 3 players have even a semblance of their bids, N's maximum club length will be 1. If so, then we don't need double to show an impossible holding (unless the opps do this sort of lunacy often). If we don't need double to say the red v white opps are idiot psychers, then we need it for something else. To me, it makes sense that double simply says I have no interest in anything else....if you, partner, thought that defending 2
♣ was best unless I had an unusual hand....well, I don't have one and I'm happy to defend 3
♣.
That allows pass to mean something else.....probably a hand with mild slam interest or better (we can pass then pull to show the better, and respect the likely double with the mild), while an immediate bid would be a strong suggestion of shape and strength.
This seems to fulfill one of the main aims of system design....maximizing the hand-types one can show while optimizing our ability to play for penalties.
However, this sequence will probably never be duplicated in your bridge playing career so maybe this is much ado about nothing...tho I think the mental processes are worth considering.
And, for what it is worth, I do suspect that most of the other posts here have been influenced by seeing the hands, in terms of the analysis of the early auction (not their views of the final action).
It would have been interesting to post a N hand with say Kxxxx KJxx Qxx x with the auction through 3
♣ and see what votes double would have got.
