They offered, with its counter-example attached, that the incoming screen's
full-screen primitive is [255] where the gap is 0 and [127] where it is 1, failing
on menu -> EXTRAS which declares a black backdrop and gives 1.
My first check got it wrong and would have dissolved their counter-example: I took
the FIRST full-screen primitive in element order and reported extras arriving at
alpha 64. extras has two such primitives; I read one and called it the screen's.
Corrected, all three GP_TITLE screens are identical in this respect -- pteff00 at
255 painting last, pteff02 at 64 -- so every one opens with an opaque black quad
on top clearing over 12-16 units, extras does arrive at 255, and their
counter-example stands.
The sharpening: within GP_TITLE this quantity is CONSTANT, so it cannot explain
any variation among the four intra-archive pairs. It could only separate GP_TITLE
screens from outside ones, which is much narrower than 'begins from black implies
no blank frame' and is already contradicted by menu->EXTRAS 1 against
menu->other-2 0, both arriving at an opaque incoming.
Their new pair kills the origin story from my side too: the menu gives {0,1,1,0}
across four destinations, both extremes from one origin.
