// Row 95 (#1589): the Board leads with the stack's held roles, from the bus `agents` read, and
// keeps the machine scan's sessions behind "Show machine sessions", off by default and kept in
// the page's settings. A redirect answer on any Console fetch is the sign-in proxy's: the page
// stops and says, in one line, to reload and sign in. The roles come from an in-process broker
// through its reader session. A script added before the page loads records every fetch the page
// makes, answers /api/config with send on (unless the URL has ?nosend), answers POST
// /api/bus/message from a queue, and answers any path in window.__redirect the way fetch does
// under redirect: 'manual' (type opaqueredirect, status 0).
