esp_mqtt_client_init() succeeded without a registered event sink when registration failed, and the WebSocket wrap returned a transport with the unpadded SDK buffer when the padded allocation failed. Both paths now fail cleanly instead, the IDF 4 WebSocket layout is pinned to the validated patch level, and the connection flags esp-mqtt tasks write become atomic.
