  "message": "Close Connection when outgoing ACK frame is empty.\n\nThis can only happen when the peer is misbehaving, sending an opportunistic ACK for a packet it could not have received. Opportunistic ACKs are potentially an attack.\n\nUntil quic_least_unacked_plus_1 was verified, the failure to clear all obsolete ACK blocks masked this bug.\n\nProtected by FLAGS_quic_reloadable_flag_quic_fail_on_empty_ack.\n\nPiperOrigin-RevId: 800613375\n",
