Under which Law is East obliged to wait for dummy to place the diamond in the played position?
East can play before dummy if he wants to, and all the law says is that he must play the card he exposed, though he will get absolutely no relief if dummy doesn't do what he expects in that case. Although the card dummy must play is fixed at a certain point, the procedures for playing the card have not been completed at that point. The key point is the identification of what is card that has been played. If East wished for clarification of the interpretation of the irregular designation, he could have called the director, so he makes any interpretation of an incomplete designation at his own risk. If East had waited for the completion of the procedures in relation to playing the card, he could then have relied upon what he sees. East isn't obliged to wait, but by waiting he can rely upon what card dummy places in the played position. He cannot rely upon his own interpretation of the incomplete designation, that is at his own risk.

South has played when he said "ten", and East followed to the ten of clubs. Are you saying that he can do so if there is only one ten in dummy, but has to wait if there is more than one ten in dummy? This allows declarer to make minimum designations in the hope of achieving MPCs.
No I'm not saying he has to wait, he can even play before dummy for all I care, but that would be obviously at his own risk. What I am saying is that if he decides to make his own interpretation of the incomplete designation, then he makes that interpretation at his own risk. He could have asked the director to make the interpretation, or waited for dummy to put a card in the played position and relied on that instead.

And for a Law 23 adjustment against SB, you need an infraction by East. There is clearly one by South, and you submit no arguments to refute the claim that South "could have been aware" his infraction would benefit his side.
That was a cheeky point by me, only relevant if I'm wrong about all the above. If I'm wrong about the preceding and East is allowed to rely upon his own interpretatino of the incomplete designation, then what I'm saying is that morally East is in the wrong and I'd like to find an excuse for such a L23 adjustment against him, because it is a coffee-house and so bad it ought to be adjustable. But I realise I am going to have to scrape the bottom of the barrel to find an irregularity to allow it.
As I said, there isn't really any sanction against East even for playing before dummy. But I would say it was a violation of the proprieties (the one about detaching a card too soon) for east to take action too soon, and I'll use L23 when it can matter. I will argue that although we reach a point where declarer's play is irrevocable before completion of the complete procedure of playing a card, the playing a card is only finished when the procedure for playing a card is finished, and that is the correct point for deciding whether East is detaching cards too soon.

And for completeness, I assume you would rule that the ace of clubs is a MPC, and West has to duck the second diamond, so 6NT=?
Correct.
