+2026-08-24, follows CT1 correction (a)): `gmPanelUI::ResizeTo
+@0x004BC6E0` is a bare tailcall to `UIElement::ResizeTo` — no clamp
+there, so the minimum lives in the generic Resizebar drag path reading
+element attributes, and the authoring to probe is the PANEL-HOST layout
+`0x2100006E`'s slot elements (Character slot per `RetailPanelCatalog`,
+sibling of social `0x1000018F`) — NOT the character layout root CT1
+probed. First CT6 step: probe the host slots' min/max + resize
+authoring, then read `UIElement_Resizebar::StartMouseResizing
+@0x0046B7E0`'s clamp source verbatim.

 the authored minimum; the stat list shows its scrollbar when the
 resized viewport overflows (the full-track/disabled behavior from the
