For the complete documentation index, see https://buildwithfern.com/learn/llms.txt. ## 4.19.3 **`(fix):`** Generated `ReconnectingWebSocketListener` now acknowledges peer-initiated close frames by overriding `onClosing`, so OkHttp completes the close handshake and `onClosed` (and the public disconnect lifecycle) fires for server-initiated closes. A no-status close (local sentinel 1005) is acknowledged with 1000, since 1005 is not a wire-valid close code. The reconnect decision is exposed as a `protected boolean shouldReconnectAfterClose(WebSocket, int, String)` hook (default unchanged: `code != 1000`) so resource-specific subclasses can treat a protocol-established terminal close as final. Adds `send(String, Consumer)` / `sendBinary(ByteString, Consumer)` overloads that report which socket directly accepted a message (not invoked for queued or dropped messages).
