Yes, I'm probably supposed to rebid 3nt not 2nt. I didn't pass 3nt since I thought North was showing club single/void, not Ax. Questions:

1. Why does North bid 3d, why not the obvious 3nt? It says 3d shows 3+d, personally I'd only bid 3d with 5440, and just bid 3nt with all 5422/5431 hands without extras. I'd bid 3c with 5413/5404. 3d seems like an unnecessary complication and sends the wrong message.

2. The 2nt bid could be more tightly defined, as 0-2 spades, 0-3 H, diamond stopped.

3. The 3s and 4s bids bid should be limited to 2 cd spade IMO, and 4s should have some sensible upper limit. 2nt should deny any real spade fit. Maybe one could argue that 3 cd spade is allowed, but def not 4/5.

What would that have shown, if 2NT is 14+?

It's pretty standard in 2/1 auctions for jumps in NT to show extra values, something like 16-17 or 15-17. Otherwise it gets too murky, difficult to reach decent slams when opener is also in that range and semi-balanced, neither knows if you are on 12 HCP or 17 HCP. I also don't agree with 2nt showing "14+ total points"; 13 is plenty.

I didn't do it here since it was a reward race that doesn't necessarily call for hyper-accuracy, plus I'm experimenting to see how GIB behaves in these type of auctions.
