Errors

import { isDialogueError, type DialogueError, type ErrorCode } from '@dialogueai/react';

// 1. The class — what the core throws (and what isDialogueError() narrows to).
//    DialogueError extends Error with:
//      code: ErrorCode          // stable, switch on this
//      recoverable: boolean     // can retry() help?
//      status?: number          // HTTP status, if any
//      raw?: unknown            // original payload

// 2. The event payload — what hooks/onError/the bus give you (no status/raw):
type DialogueErrorEvent = { code: ErrorCode; message: string; recoverable: boolean };
