Everything shown is read from viewer-data/ (written by export_viewer.py; #data=local reads the local export under
data/out/); nothing is uploaded. Review checks, the panel state and the sheet filter are kept in this browser only. Upload, the confirmation steps before a run, editing and the
downloads of the workflow study need the app and are not part of this viewer.
