As for blame for the poor result, we are not told what the score would be for 3N, but we do know that it would be more than 15.5%. Since it is N's fault that 3N was not reached, and probably his fault that slam was not reached (I mean, how slammish should S be with a 10xxxx trump suit that was not raised immediately?), I'd give all of the blame to N.

The scores are hidden, below the score of 5+1. Apparently it was hidden too well :P

The score for 6N is misleading, you've got to make it, and while you can on a heart lead, you're far from guaranteed to get this right. My suspicion is that 6N by S will succeed, but 6N by N will fail a fair bit of the time where the finesse gets taken rather than the black suit squeeze played.

If they go heart-heart you cash your minors and the double squeeze is automatic. You come down to a spade, the H9 and a club and dummy has AKJ of spades.

East could break this up if he gets to win the HQ and finds a spade shift, but that would be an unnatural and extremely good/thoughtful play.

Edit.... deleted due to another "brainfade"...
( I mixed up what was the trump suit )...
( If Cl are trump, yes you can stop in 5C using Minorwood because the K-ask is "kickback for kings" .... hence 5D! = king-ask )

twoferbridge???? You can never play 5c after you minorwood? Do you also play

1S-4S
4N-5H
5S

as specific King ask?
... and I can prove it with my usual, flawless logic.

Here is the revised bidding for Cl as trump.
After finding all of the key cards, 5D! = specific K-ask.
When no hK is found, Opener abandons the grand attempt and settles in 6C:

1D - 2C
2D - 2S ( GF w/5+Cl )
4C! ( Minorwood) - 4S ( 2-cQ )
??
  4NT = to play
   5C = to play
   5D! = kickback for kings ( specific )

5D! - 5S ( sK, but no hK )
6C

3H is fine, it's not a 2/1 auction it's a sayc auction. So 2C then 2S then 3D shows real diamond support since 3D over 2D is NF. Ergo 3H.

I bet its not sayc but french std or alike rather. At this side of the atlantic ocean 2-2-3 is forcing (might be proven wrong)

3 is wrong and the beginning of troubles, 5 is trying to define the strenght don't see it badly at all.

And the final pass is anti-percentage. It has taken me time to find a hand where 5 makes and 3NT doesn't. And chances of 630-660 are huge. Sure it might strike gold, but it is anti percentage. It just takes a partner who made a GF bidding to have Q+A to count 12 tricks!, the correct bid is not even 6 but a grand try.
