F18VB: Actual pictures of the Infusion, cads with angles and else were provided at working party, the AC72 rules was also analyzed.

They said it was going to be all published, but not todate.
I challenged every single option you can imagine, even an hexagonal shaped hull (cross cut) where no center plane could be defined if dagger case used canted joining two angles of the hex.

With the Inf and this came the lengh of the daggers coming outside the width limit on 260cm.
And with the others contribution they reach that wording.
Although I didn´t have the final "cut" on wording as they said it was enough with above.

I think it covers most of your points though.
