And, no 4 over 4? Lastly, is it standard for 5 to deny both top heart honors, when South hasn't yet been given a chance to show first-round control?

This is not a bug, but deliberate action by North.

There is a scenario when GIB makes fake cue with K, pretending it's Ace if it has a void and values for slam.

Something like GIB's 'last train'. Aceless, but with sufficient points + void. GIB doesn't show voids as cue except using Splinter or 4NT answer 5NT/5X showing even/odd + void.

With other values it would bid Splinter, but too strong now as splinter is limited 13-16TP.

It will be addressed for improvement. But currently it's as per design.

South could discover this using 4NT instead 4. If GIB had a void in diamonds or hearts ( for sure void is not in clubs as it would pretend it has other ace ), as the advantage here is trump is the superior spade, it will be shown. GIB would reply 6 and all would be clear.

4 doesn't change probable further action as if North replies 4 South would bid 4NT anyway.

And 5 denies AK as 5 is below 5 call and it was skipped by South.
