THREE THINGS FROM THE DECODER, one of which I am not taking. REFUTED: "the developer splash is one composited quad, the bounding box of the three logos". The observed quad is 525x259 at (378,155). The three logos' bounding box is 500x421 at (390,164) -- a 259-tall quad CANNOT contain them, and palogo_anima alone starts at y=449, thirty-five pixels below that quad's bottom edge. The observed quad matches the union of gamearts_eff and seta_eff, 521x261 at (379,154), to about four pixels in every dimension -- and both of those are TRANSIENTS my own census flagged, dark by t=45, so a frame containing that quad is a build-in frame rather than the settled screen. I cannot see their draw stream, so I sent the arithmetic rather than a verdict, and the port keeps drawing three: I will not stop drawing an element on a claim whose stated identification excludes that element from its own bounding box. THE BLACK HOLD IS 9 UNITS, NOT 12. I authored 12 from Q7's luminance plateau of 0.17-0.23 s, supported by the menus' transition quad. The Decoder counted SUBMITTED QUADS instead -- luminance cannot separate the outgoing fade's tail from true black. Four frames with no sprite quad at all, at 2.284 units/frame derived from the disc as its own clock, gives 9.1 units = 0.152 s (6.9-11.4). That overlaps the luminance figure only at the top, and the true black is SHORTER still since both boundary frames carry picture. My 12 was supported by analogy -- a different screen's quad on a different path -- and a number that fits by analogy loses to one measured in place. verify-dwell's bound moved with it; both screens still agree. THE TITLE'S SWEEPS LOOP. The oracle shows the quad oscillating over its whole x range and resetting hard, one reset in the first title dwell and two in the second. The loop-length field could NOT have settled it, correcting a hope I had stated: both records declare exactly their last keyframe time, slack zero, and "loops at 600" and "runs once for 600 and stops" write the identical header. Verified on the two sweeps' LCM, since their periods differ: 600 and 720 realign at 3600 units, mean diff 0, against 0.438 at half that. Scoped to the title. The menus declare the same lengths but the oracle measurement is of the title, and my own weak evidence points the other way there -- best match with the sweeps off-screen, three times worse mid-screen, against a 73% on-screen duty cycle if they looped. Two weak signals in opposite directions is a reason to scope, not to pick.
