 #  28. (Phase 70) WIN_WORKSPACE macro applied to remaining frame->workspace
 #      reads in actions.c, cycling.c, event.c, moveres.c, placement.c,
 #      switchpanel.c, wmspec.c, workspace.c; write sites keep direct access.
+#  29. (Phase 71) Early-return guards added to wShadeWindow, wUnshadeWindow,
+#      wMaximizeWindow, wUnmaximizeWindow, wFullscreenWindow, wIconifyWindow,
+#      wDeiconifyWindow so that Wayland windows (frame==NULL) do not crash
+#      when these actions are triggered (build-only check).
 #
 # This test grows as wl_backend vtable slots are implemented.
