Sidebar and status bar
Three sidebar panels mirror your workspace: Workspace context (account mode, role, active scope), Handoffs (the active scope's handoffs), and Integrations (resource health and provider coverage). A status-bar button shows the active scope and lets you generate a handoff in one click.
The filter panel for handoffs and insights uses the same real, selectable values returned by the filters endpoint – see Filters.
