    Variable FEED_SURFACE_MODULEConst

    FEED_SURFACE_MODULE: "feed_timeline" = 'feed_timeline'

    Module the feed request reports as the surface it is loading, whatever screen is in front when it goes out (the 448 post-login flow sends it while the login home is still the client endpoint). A property of the feed request, not of the navigation state.
