The port measures four elements as rendering too dark against the capture -- ptframe1/2 on the main menu, ptframe3/4 on EXTRAS -- with the shortfall correlating +0.77/+0.80 with the BACKGROUND and only +0.24 with the element's own contribution. That is the signature of a blend that scales what is already there. It asked whether the disc selects one. Three examples, one negative, wider than the one I gave last iteration: * frame_alpha_census -- every T8aD sprite on builds 5 and 6 by alpha. It REFUTES the port's own sharpener: 'neither frame has a single fully-opaque pixel, against ptbase's 99.1 %' is true, and pteff10 (max alpha 130, 100 % partial, no opaque pixel) is measured by the port as NEARLY EXACT. So being wholly semi-transparent is not what makes the frames special. * frame_vs_accurate_words -- all 12 T8aD header words for both screens, plus a per-BIT sweep of +0x04 and +0x08. NO word and NO bit puts the four frames on one side and pteff10 on the other. It also kills my own remaining candidate a second time: +0x08 = 0x8050 is shared with pteff21/22/23 on EXTRAS. * frame_keyframe_unknowns -- the keyframe record's fade, tint, rotation and its two unexplained signed words. unknown_4 and unknown_8 are ZERO on every keyframe of both screens, so they carry nothing here; no frame takes a value of any field that another element does not. Reach: the 60-byte declaration entry, the T8aD header word-wise and bit-wise, and the keyframe record. Four elements, two screens. Not the executable's draw path, which is the next commit.
