GENERIC PLEX SALVAGE
====================

Scan:
  ./scan.sh '/Warez/Books'
  ./scan.sh '/Warez/3D Printing'
  ./scan.sh '/Media/Some Folder'

Recover:
  ./recover.sh '/Warez/Books'

The source tree is mirrored beneath /mnt/recovery:
  /Warez/Books -> /mnt/recovery/Warez/Books

The scan creates uniquely named manifest/summary files under /mnt/recovery.

Classifications:
  SAFE
  LOST
  ETB_LOST
  ETB_SURVIVES
  UNKNOWN
  OTHER

Only SAFE files are recovered.

Safety:
- damaged LV must remain kernel read-only;
- /mnt/recovery must be a separate mounted filesystem;
- filesystem root "/" is refused;
- ".." is refused;
- each file is dumped by inode;
- dumped byte size must match inode size;
- existing same-size recovered files are skipped;
- at least 2 GiB free is preserved on /mnt/recovery.
