How is this hand supposed to be bid in GIB's system? I would have thought 2♥ would be forcing. Perhaps GIB saved me as I would have gone down in 4H . . .

With bid over the rebidded opened suit by rank. In second or third level which comes first.

As currently GIB doesn't play Drury ( it could be implemented in one of next updates, but currently GIB doesn't use it)

New suit by passed hand is not general forcing, just shows max passed hand and 5+ in the suit.

So:

P - P - 1♦ - P
2♣ - P - 2♥ - New suit -- 3+ ♦; 4+ ♥; 21- HCP; 15-22 total points


P - P - 1♠ - P
2♣ - P - 2♦ - New suit -- 4+ ♦; 5+ ♠; 11-21 HCP; 12-22 total points
2♣ - P - 3♦ - -- 4+ ♦; 5+ ♠; 21- HCP; 15-22 total points; forcing to 3N

So if you rebid new suit under the rebidded opened suit, which makes it lower rank, it's not typical forcing so GIB could raise, but it's not forced to do it.

Probably the explanation should be tweaked as shows too high range of points, which could be up to 15-16. As with 16+ you should rebid something else based on max hand in partner.
Like 11-21HCP must be 11-14HCP and 12-15TP. Sort of.

South needs to jump to force in this auction. If you bid 3♥, North will raise to 4♥.

Besides the explanation of 2♥ not showing the correct upper limit, there's another bug. I asked GIB what it would bid with your hand, and it also bids only 2♥. The problem seems to be with the rule priorities: the rules for 3♥ have lower priority than the rules for 2♥, and the latter rules don't have an upper limit on their strength to keep them from being used.

I've already complained about this. Even barmar could hardly believe it. But it doesn't seem like anyone cares to actually fix it.

There are lots of bugs in GIB's bidding, we can only get to so many of them in any period of time.

Well I'm glad that it's accepted as a bug now, that was not the impression I got last time.
