Both call sites (LoadFilesAsync, OnDisplayedDiffChanged) ran the parser synchronously on the dispatcher, freezing the window on a large diff. The Files-mode parse+tree-build now runs via Task.Run behind a ParseOp OperationStatus wired to the toolbar; the planning-mode parse is fire-and-forget with a generation counter so a fast second DisplayedDiff change can't write stale PlanningFiles.
