 ## Error Handling
 
-Each platform defines its own `ErrorCode` enum. The enum is re-exported from the crate root as `onepassword_ipc_client::ErrorCode`.
-
-### macOS ErrorCode
-
-| Value | Description |
-| :---- | :---------- |
-| `InvalidArguments` | Invalid arguments were provided (e.g. bad endpoint name). |
-| `UnexpectedOsError` | An unexpected operating system error occurred. |
-| `RegistrationError` | Failed to register with the Mach port. |
-| `CorruptMessage` | A received message was malformed or corrupt. |
-| `MessageTooLarge` | The message exceeds the maximum allowed size. |
-| `FailedToSend` | Failed to send the message to the Mach port. |
-| `NoReply` | No reply was received from the server. |
-| `Internal` | An internal error occurred (e.g. unexpected empty response or invalid chunk). |
-
-### Linux / Windows ErrorCode
+All platforms share a single `ErrorCode` enum, re-exported from the crate root as `onepassword_ipc_client::ErrorCode`.
 
 | Value | Description |
 | :---- | :---------- |
 | `InvalidArguments` | Invalid arguments were provided (e.g. bad endpoint name). |
-| `FailedToConnect` | Failed to connect to the Unix socket or named pipe. |
-| `FailedToSendMessage` | Failed to write the message to the connection. |
-| `FailedToReceiveResponse` | Failed to read a response from the connection. |
-| `FailedToEncodeMessage` | Failed to encode the message into the wire format. |
-| `FailedToDecodeMessage` | Failed to decode the response from the wire format. |
+| `FailedToConnect` | Failed to connect to the IPC endpoint. |
+| `FailedToSend` | Failed to send the message. |
+| `FailedToReceive` | Failed to receive a response from the server. |
+| `FailedToEncode` | Failed to encode the message into the wire format. |
+| `FailedToDecode` | Failed to decode the response from the wire format. |
 | `ServerClosedConnection` | The server closed the connection unexpectedly. |
+| `Internal` | An internal error occurred. |
