The image file is outside the allowed working directory and cannot be read — it's in `/var/folders/…/T/` rather than under `/Users/jheppler/work/chnm/pwd`. The transcription script must be placing temp files somewhere the session can't access. To fix this, the temp directory for images should be created inside the project or the scratchpad directory. The transcription script likely controls where it writes the temp files — check `_transcription/transcribe.py` or `scripts/transcribe.py` for the `tempfile` or path logic and point it at the scratchpad or a path under `/Users/jheppler/work/chnm/pwd/`.
