What was changed

• The white skirt is gone. This was the real problem, and it was not an alpha problem at all — the drop shadow had been baked in as fully opaque near-white pixels. Invisible on a white page, a pale blob on a dark one, and invisible to any amount of alpha cleanup. Removed by flooding in from the edges of the canvas through bright, desaturated pixels, which climbs until it meets the dark saturated rim of the badge and stops there. The silver ring sits above that rim, so it survives.
• The white matte is gone. Edge pixels had been composited over white, so a 60%-alpha pixel next to rgb(39,30,29) artwork was reading rgb(251,247,246). Recovered with fg = (c − 255(1−α)) / α.
• Shadow spill cut below α=24, and the alpha ramp tightened from about three pixels to one.
• Render dust removed. The file carried disconnected fragments, some fully opaque, sitting up to 68px below the badge. Only the largest connected component is kept — a plain trim would have preserved them, which is why the canvas was 780×805 for 695×717 of artwork.
