Reverting the fix (serve_attach's controller arm to send_effect with ack=true, or dropping the dispatch_input `if req.ack` gate) re-introduces the deadlock and flips this RED. note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace test input_flood_through_serve_attach_does_not_deadlock_broker ...
