Start by locating the UI implementation for the “Scheduled” pill and compare it with the “Background” and “Artifacts” pills. Reproduce the scheduling flow described in the issue, then make the scheduled state either interactable or visually distinct; done means its behavior and appearance no longer imply conflicting affordances.
