    Interface ChatAttachment

    A file (image or PDF) attached to a user message.

    Bytes travel inline as base64 data until the worker stores them (R2 backend), after which the widget keeps only the storage key and a signed preview url. Persisted history never includes data; an attachment with neither data nor key is shown by name only and described to the model as no longer available.

    interface ChatAttachment {
        data?: string;
        expiresAt?: string;
        id: string;
        key?: string;
        mediaType: string;
        name: string;
        size: number;
        url?: string;
    }
