The pane used to split the pipeline across two languages: the ILAst language stepped the IL transforms, the C# language stepped the AST transforms, and nothing showed the seam between them, so a step index meant a different thing depending on which language happened to be selected. Recording both halves into one Stepper makes an index replayable across the whole pipeline; a limit that lands in the IL phase has no C# to print, so the halted function is rendered as ILAst instead. Which function that is takes some care, because a member group's EndStep is the next member's first step: a halt standing on a member's opening step belongs to the member that just finished, a transform that throws where the limit was aimed has to hand over the ILAst it half-transformed (what the ILAst language showed as "ILAst after the crash"), and a step recorded on a helper function the pipeline has not attached yet belongs to that function's own tree. Retention stays opt-in twice over: the decompiler records IL steps only when asked to, and the pane asks only while its view is on screen. Every kept step pins the ILAst it captured, which for one type runs to tens of thousands of nodes, so a closed pane would be paying for a tree nobody displays. What is left of the ILAst language is its typed-IL dump, which runs no transforms at all. That stays, as TypedILLanguage. IDebugStepProvider was down to a single implementation and is removed.
