The image files appear to be empty or corrupt (zero bytes). The transcription script likely failed to download or write them before invoking me. The files at the provided paths contain no image data — they read as all-zero bytes. This usually means the download from the media server failed silently before the transcription process was called. To fix this, check that: 1. The image download step in `_transcription/transcribe.py` (or `scripts/transcribe.py`) is verifying the response status code and file size before proceeding. 2. The media URL (`https://obj.rrchnm.org/wardepartmentpapers.org/files/original/...`) is reachable from wherever the script is running — these are served from object storage and may require the correct hostname.
