The port asked whether a blend field exists and whether _eff layers draw
additively, naming it as their largest remaining oracle gap. Both answers are no
and the cause is already decoded.
Additive blending is refuted specifically: T8aD +0x04 bit 0x02 as an additive
selector was tested and every measure worsens against the capture. The export
carries no blend field because none has been found -- the per-draw capture
records primitive type, index count, shader hashes, texture bindings and vertex
attribute 0, but no RB_BLENDCONTROL, and reading real blend state needs a Canary
change that is blocked here.
One of their three eliminations is overturned. They ruled out the ptloop sweeps
as 399x180 at (441,270) with keyframes holding position constant -- that is the
unscaled, unrotated geometry. Measured off a GPU draw capture, the live title
submits two rotated quads: ptloop01 at 400x1076 rotated +30.26 degrees centred
(992,359), and ptloop02 at 400x1444 rotated -45.28 degrees centred (467,360),
the scales being 600 and 800 percent. Two quads at x about 467 and 992, leaning
opposite ways, is exactly their signature of darker centre-left and brighter
right nearly cancelling. Our own renderer shows the same residual from the same
cause, tiles running -38.6 then +33.8 across the band, so it is a shared decode
gap rather than a defect in their compositor.
The rotation itself is decoded: keyframe block +12, degrees, clockwise-positive,
confirmed against a framebuffer capture. So their biggest oracle gap and the
rotation question they raised for the human are the same item.
