Kinds are bucketed to a fixed vocabulary on the way out (anything else counts as other), so a free-text kind can never carry a note's words here.
This page reads /notes/stats, /stores and /, and nothing else. The diary is the writer's; a browser pointed at this port gets the counts and the backups, and nothing to read.
Snapshots are the database and the keepsakes folder, copied whole; a listing says nothing of what a note says. The archive leaves this box only with backup.allow_pull.
