Reverses two of my own pages. t32-blend-mode-not-on-disc.md said the mode is not
on the disc; ui-blend-mode-measured.md classified it measured and told the port
that which field selects it was unknown. Both were honest and neither is current.
Bit 0x02 of +0x04 set means the game draws that sprite ADDITIVE
(RB_BLENDCONTROL0 = 0x01010101); clear means premultiplied alpha-over.
Fit: 35 elements over three screens, 16 set/additive and 19 clear/alpha-over,
zero errors, every label read out of the guest command stream rather than off a
render.
Control: of every bit of the first twelve header words, exactly one separates
those 35 without error. Nothing ties with it -- which is precisely what the
+0x08 = 0x8050 candidate failed.
Within-pair: ptbtn00 0x0110 alpha-over against ptbtn00f 0x0112 additive, same
screen, same bundle, adjacent draws, one bit apart. And other f variants are
bit-clear and alpha-over, so it is not 'focused variants are additive'.
Out of sample: a prediction committed at 088df91, before its capture, on a
different archive -- GP_OPTIONS entry 19, 3 additive of 16, falsified if any
other element drew additive. The game drew exactly po_menu_eff01/02/03 additive
and nothing else.
This revives a claim REFUTED.md killed. The refutation said blending those
sprites additively worsens every measure against the capture -- a claim about
our renderer, made while that renderer had a stale keyframe association, no leaf
geometry and no rotation. Recorded as a revival with its evidence;
check_refuted.py passes with 0 unmarked assertions.
Two other readings of the same bit stay refuted and are explicitly not revived:
'the name contains eff' and 'premultiplied storage'. Those were the bit's
meaning; this is its effect.

⚠️ WHAT IS AND IS NOT IDENTIFIED HERE
|
|
* the three ADDITIVE quads are named, and they are the three predicted ones.
|
|
* the alpha-over side is a COUNT, not 13 individual identifications: draw 1 is
|
|
a 20-index batch of tiled background quads at 320x360, a size several
|
|
elements share, so the matcher's label on those rows is a candidate. What is
|
|
measured is that no draw on the screen carries 0x01010101 except the three.
|
|
* that asymmetry is the right way round for a falsification: the prediction
|
|
would have died if a fourth additive draw existed, and none does.
