The human chose Option A: teach sylpheed-formats own renderer to draw rotation_deg so it and the port stay comparable and verify-screen keeps meaning someone is wrong. Three pieces, because rotation alone does nothing on the title. blit gains a rotated path that draws by inverse mapping over the rotated bounding box, turning about the pivot, whose absolute position is invariant under scale; zero rotation keeps the original forward-mapped path byte for byte so non-rotating screens cannot regress. compose draws a nested .rat leaf when the leaf carries geometry the parent does not, which is the sweeps case, but not as a blanket rule since a button s leaf duplicates its parent. And --at poses leaves at a keyframe time, because the sweeps hold off-screen at x=1521 so a resting composite omits them. A trap found the hard way: posing EVERYTHING at one global time is wrong, because a top-level group s final keyframes are its exit ramp and rest() deliberately stops before them. Posing the title at t=358 walked every parent into its exit and drove the disagreement from 10.92 to 61.74. So at poses leaves only. Controls: 0 and 360 degrees byte-identical to the unrotated path, 90 degrees swaps a 10x4 to 4x10, area conserved within 15 percent, centroid stays on the pivot. 116 lib tests pass, main_menu unchanged at 9.26. And the verification did not show what it was meant to, which is reported rather than buried: scanning the pose time against the title capture gives 10.73 to 11.17 against a 10.92 baseline -- flat, no minimum, best 1.7 percent. The whole-frame mean is dominated by the tone curve, and the renderer still does not draw ptlogo1/ptlogo2 at all, which is a far larger spatial gap than two translucent sweeps. So rotation is correct in isolation and no screen regressed, but whether it closes the port s 1.81 percent is not established here.
