The user's linked Writ desktops (there can be several): which are connected right now, and how many local workflows and personas each offers. action='list' (default) shows them; action='use' device= scopes this connection to one: runs (writ_run_workflow), browser sessions (writ_browser_use), desktop workflows (writ_list_workflows, runs_on='desktop') and desktop personas (writ_personas, source='device') then target it, and its run history (writ_workflow_runs), data (writ_workflow_data, writ_search_data) and monitors (writ_create_monitor, writ_wire_monitor; action='monitors' lists them) are read from and created on it. action='clear' removes the scope. A desktop's personas sign in from its own vault: the credentials never leave it. For: work 'on my laptop' or 'on my work computer', or in the user's own browser with their logins.
