Whether 3♠ is forcing is a matter for agreement. For me it is, even in the partnership in which I play that 2♠ is not gf. Yes, we may sometimes over-reach, but the gain in being able to set trump relatively economically outweighs the occasional overbid.
However, saying that 3♠ is forcing for me is not the same thing as agreeing that it is the correct bid.
North has, in context, a great hand, containing a lot of features likely to be of interest to partner. His possession of both minor Aces and the ♠AJ make it probable that South will be reluctant to take charge on hands on which small slam is eminently playable: on this hand, several routes lead to slam even over a conservative bid by North but only because South has extras himself. North cannot assume that happy state of affairs, so should do his best to let partner in on the secret.
3♥ is one way, but is too flawed for me. Partner cannot know that 3♥ was in support of ♠, so may well make a rebid that eliminates any sensible auction.
4♥ is my choice: a splinter, showing good trump, a stiff ♥ and significant extra values.
Once again, agreements are useful. Thus, for me, a splinter in the suit just below our trump suit is a rare bid: I like to have an intervening step available as Last Train.
Also, some people use splinters in this type of sequence without much extra: I don't like that approach.
I would, admittedly, prefer to have an extra trump (I'd also like to have more hair on my head), but AJx is okay given that partner rates to have 5 good or 6 decent. Besides, my minor suit controls are such that partner will not go nuts on me without decent trump.
The splinter will get South very interested. It is so unlikely that NS are off 2 quick ♣ tricks that I would make an exception to an almost rigid rule: I would keycard despite having xx in an unbid side suit. I can do this because 4♥ promises extras, and slam interest, and my ♠/♦ holdings are so good that partner has to have some ♣ control: if it is the King, the odds are high that the Ace is onside after the weak jump overcall.
After 4N, we get a 5♦ response (1430) and we can bid 6♦ as a grand slam try.
Partner will bid 7 on the basis of the ♦Q.
Now, I admit that South will have invited the grand without being certain of 13 tricks: opener could be 4=1=4=4.
If so, then opener could have the ♦J, or the J could be doubleton, or he may have the ♣K, or there may be a squeeze, and so on: imagine North with AQxx AJxx in the minors and west with J9xx and KQxx... surely possible after a weak jump overcall.
So 13 tricks may be laydown, and if not, there will likely be a play.
