Question regarding weapon cost

I'm a little confused.

People seem to be saying that

A)Peace Treaty/ISS don't "remember" what you paid for the weapon.
B)They don't take into account discounts that were actually applied, but do take into account discounts on the minion that currently possesses the weapon? (i.e. a gun that black cat equipped and then gave away would "cost" 2, but a gun that someone else equipped and then gave to Cat would "cost" 1.

This is odd, since it seems that it conflicts with these rulings about Khobar Towers (which also refers to pool/blood "cost"). The upshot of these was that Khobar "remembers" what you paid for X cost allies (reanimated corpse), but doesn't count discounts like charisma.
