The user's first click on a mapping button killed the client: the live
dialog catalog's wait root 0x31 carries retail class type 0x19 (WaitDialog),
which DatWidgetFactory left unmapped, so the root built as a plain
UiDatElement and RetailWaitDialogView's ctor threw out of UiButton.OnClick
into the render loop. The unit test missed it by standing the confirmation
fixture (type 0x13, mapped) in for the wait root — the structural-false-
negative class again. Pins: DatWidgetFactoryTests theory for both dialog
root types, plus an installed-DAT UiDialogRoot/0x3D/0x3E assertion in the
env-gated keyboard probe. OpenCaptureInstructions now converts a dialog
construction failure into its contracted 0-return (log + capture refused,
retail's own OpenMapWarnDialog failure shape) instead of crashing.
