- git mv UiChatScrollbar.cs → UiScrollbar.cs; rename class + update doc summary to
"Generic scrollbar. Ports retail UIElement_Scrollbar (RegisterElementClass(0xb) @
acclient_2013_pseudo_c.txt:124137); thumb size = trackLen * ThumbRatio (min 8px); step ±1 line."
- git mv UiChatScrollbarTests.cs → UiScrollbarTests.cs; rename test class + replace
every UiChatScrollbar reference with UiScrollbar (bodies unchanged).
- DatWidgetFactory: register Type 11 → new UiScrollbar() before the _ fallback case.
- ChatWindowController: change Scrollbar property type to UiScrollbar; replace the old
"construct-remove-add" block with a "find factory-built UiScrollbar and bind in place"
block (no RemoveChild/AddChild); keep `var track` assignment in scope so the Max/Min
block's track.Left/track.Width reads still compile against UiElement?.
- AP-41 divergence register: update file:line to UiScrollbar.cs:35; narrow wording to
"fallback only — single-tile drawn only when cap ids are unset; the chat controller
passes all three cap ids so the 3-slice path is the active code path."
- Update inline UiChatScrollbar doc-comment references in UiScrollable.cs + UiChatView.cs.
- Full suite: 399 passed, 2 skipped (dat/tower fixture skips), 0 failed.
