That leaves open the possibility of a corruption due to a crash then; from
SQLite docs: "Without a journal, there is no way for a statement to unwind
partially completed operations following a constraint error. This might
also leave the database in a corrupted state."
Which is probably what happened; my mount logs show the following, which
correspond to the time the corrupt DB was created (though the disks all
have several GB free, so I'm confused as to the cause of the error):
