An attachment a translator could not represent was dropped without a word, and a turn whose only content was that attachment went upstream as an empty messages, parts, or input array. The model then answered as if nothing was attached, or the upstream rejected a request that never named the attachment. A base64 document now reaches OpenAI as a file part. A file the target cannot receive, such as container_upload, an OpenAI file_id, or input_audio sent to Claude, is reported by name so the route answers 400 instead of forwarding an empty turn. Text beside it still travels. One rule, ErrIfNothingLeft, decides when to refuse, and RegisterCheckedRequest carries the refusal on the request envelope. Every executor that translates checks it before calling upstream. The exported converters keep their []byte signature, so no caller or sibling test had to change.
