I worry that my snapshotting config is unsound. Would someone be so kind as to tell me if the list of snapshots at https://pastebin.com/RJu93K0N is messed up? A line like
ID 555 gen 139816 parent 479 top level 479 path @/.snapshots/171/snapshot/.snapshots
does not look very well-formed. Do I need to reconfigure snapshots?
Also, none of these snapshots – except 1 – show up in
sudo snapper list
Is it an inconsistent result?
I currently have:

Obviously something is broken on your machine.

I’d be happy to completely remove and reconfigure my snapshots, starting from the current one. Snapshots is just not my domain of expertise, so I’d be interested to identify exactly the cause(s) of my issues, if any.
This does not look like btrfs. Should look like this:

Most likely /.snapshots mount point is missing. Post output of
btrfs subvolume list /
btrfs subvolume get-default /
cat /etc/fstab
snapper list
I suppose it IS well-formed. Post the output of this command:
sudo snapper list-configs
