The file at that path is not a valid image — the detected bytes (`37 38 34 37 32 2c 34 31`) decode to ASCII text (`78472,41`), suggesting a CSV/data payload was saved with a `.jpg` extension rather than an actual image. The transcription pipeline likely wrote the wrong content to this temp file. I cannot produce a transcription without a valid image. The file needs to be re-fetched or the pipeline that stages the image for transcription needs to be debugged.
