+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.
