I didn’t see a design document so far (which would have been handy for [troubleshooting](https://help.nextcloud.com/t/desktop-client-3-4-0-destroys-local-time-stamp-and-keeps-uploading-data-to-server/128512)) so the only source of truth would be the code.

In general having two columns in the DB is definitely nothing which happens without intention. A good reason I could imagine is track glitches between NC database and storage… another intention could be a situation when you e.g. share, comment, un/delete the file etc and you want to keep storage attributes untouched but track this “update” inside application.
