# Exercises the HTTP -> nx_kernel publish bridge: authorized
# POST /activity with the kernel gen_server running gets routed
# through nx_kernel:publish/1; the response carries the
# resulting CID. Without the kernel running, the route falls
# back to the auth-only stub (covered by http_post_activity.sh).
