Syncthing doesn’t/shouldn’t chmod the sync folder itself, instead leaving it at whatever it’s already set to. Your output at the end says you’re looking at /var/sync which is above the sync folder at /var/sync/default so Syncthing should definitely not being doing chmods there. So, not sure what you’re seeing.

The exception would be if /var/sync is where you’ve told Syncthing to store it’s config and database. That directory does get chmodded to 0700. But it looks like you’re using /root/.config, so I don’t know.
