Owner report (2026-08-24): our scrollbar arrows pointed the wrong way, the thumb vanished when there was nothing to scroll, and neither the thumb nor the arrow buttons reacted to hover/press. All three are one retail mechanism we had not ported: 1. Seating: UIElement_Scrollbar::UpdateScrollingArea @0x00470AA0 moves the INCREMENT designee (attribute 0x77) to the top/left corner and the DECREMENT designee (0x78) to the bottom/right, ignoring authored positions. The vertical base skin (0x10000455 in layout 0x2100003E) authors the DOWN-arrow decrement at Y=0 and the UP-arrow increment at Y=32 (live-DAT probed; sprite art visually verified from decoded PNGs), so our authored-Y ordering drew both arrows upside down. DatWidgetFactory now seats by designation; the hand-wired sites (CharacterStatController, ExternalContainerController, the Config/Vendor menu chrome) share the new RetailScrollbarChrome catalog instead of local constants. 2. Full-track thumb: UpdateLayout @0x004710d0 sizes the thumb from proportion attribute 0x88, which DEFAULTS to 1.0 — a content-fits bar shows a thumb filling the whole track; disabled only removes input and the page regions. Our draw skipped the thumb entirely on !HasOverflow. 3. States: every arrow button and thumb slice authors Normal (red gem / dark navy), Normal_rollover (amber gem / bright blue) and Normal_pressed (gold highlight / dark) media. The widget now tracks thumb hover and selects rollover media on hover and pressed media while dragging; the factory extracts the thumb-state media for both the 3-slice and single-sprite thumb shapes. ScrollbarSkinLiveDatTests pins the designations and state media against the installed DAT so a revision or importer regression fails loudly. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
