I've played around with an image of the system-root volume and none of the repair and rescue things I've tried is actually improving things.
You expect us to second-guess what you may actually have done?
btrfs check --repair btrfs check --init-extent-tree btrfs rescue chunk-recover
Try btrfs restore.
I did (after posting my last message). I still need to figure out how to only recover the content of the 1974 snapshot that is the current root. A full restore with snapshots infinitely recurses into /.snapshots/1974/.snapshots/1974… so it will not complete. But even if I do that the other question is still how to re-initialize the volume with a sane btrfs filesystem that has all the necessary subvolumes and the same UUID. Actually I'd want to create that someplace else in an image file so I can check it before I finally try to dd it into the place of the current botched volume. Another option would probably be to do a new installation, replacing the current sysroot and picking up the /home volume.
