"""Token enforcement on the live Secretary chat (Phase 5).

Mirror of ``test_prompter_live_auth`` for the ``secretary_live`` router, which
previously had zero auth on any endpoint. The same ``require_panel_token`` gate
applies at the route level. The Secretary's *authority* (directive execution)
is gated separately at ``/api/secretary/directives``; this only closes the
live-chat transport.
