First end-to-end pass I have actually seen: all six asserting checks ok, oracle
captures at 0.00-0.35%, verify-screen's 2 DIFFERS allowed for its stated reason.
My two earlier attempts produced nothing -- one killed by my own timeout with
block-buffered output, one wedged by the ffmpeg hang -- while I reported 'still
two lines, both ok' for three iterations. I was treating absence of output as
patience.
Their discriminating test holds, prediction written down first: incoming build 4
gives an 8-frame decay, build 5 a 5-frame one against my predicted 6. Their tell
reproduces from my export independently -- main_menu settled is [64], title's
opening pair is [255,64], composite [64,255,64], and no single element produces
it.
The consequence neither of us predicted: A title->menu is sequential with a real
~5-frame black interval, B menu->title has NO black interval -- the incoming title
draws at frame 34, before the outgoing quad ramps at 40. boot.gd applies
black_hold uniformly, so the port inserts ~9 units of black on B that the game
does not have.
Not changed. One run of one transition is exactly the generalisation they just
named as the error under two of their own wrong readings, and their second caution
is that the A figure may be a load rather than a designed hold. Recorded as a
known, stated divergence with a BLOCKED ask.
