PLEX BOOKS UNKNOWN SECONDARY CHECK
==================================

This tool reads:

  /mnt/recovery/plex-books-manifest.jsonl

and inspects only entries previously classified UNKNOWN.

It NEVER writes to the damaged ext4 filesystem.

It uses debugfs catastrophic/read-only mode and classifies UNKNOWN files as:

  ETB_LOST
    One or more extent-tree metadata blocks live inside the known-dead PV.

  ETB_SURVIVES
    Extent-tree metadata blocks are outside the dead PV; investigate further.

  EXTENTS_RECOVERABLE
    The file now exposes parsable data extents and none overlap the dead PV.

  DATA_OVERLAP
    Parsable data extents overlap the dead PV.

  OTHER_UNKNOWN
    Metadata still cannot be interpreted.

Known-dead filesystem blocks:

  3418636288 - 4395389951

Run:

  mkdir -p /mnt/plexunk
  mount -o ro LABEL=PLEXUNK /mnt/plexunk
  bash /mnt/plexunk/CHECKUNK.SH

Results are written to:

  /mnt/recovery/plex-books-unknown-check.tsv
  /mnt/recovery/plex-books-unknown-summary.txt
