Use when the ask names the flow of an existing multi-step task but not the exact edit — step traversal, async states, escapability, draft safety ("this wizard loses my draft", "there's no way out"). Propose-only: records up to five ranked findings on the surface's design ticket; dx-design-execute builds accepted ones. A stated edit ("add a back button to step 2") or a brand-new flow is dx-design-execute's. How steps behave is flow; how a page is structured is dx-design-pattern. NOT for a whole-page review with no dimension named — that is dx-design-critique.
