  "definition": "F2FS roll-forward recovery reconstructs selected post-checkpoint file updates from recovery-marked node blocks.",
  "note": "Skipping this path changes the recovered view and is not equivalent to disabling future checkpoints. In upstream v6.16, orphan-inode recovery precedes the fsync-data recovery selection; suppressing roll-forward is therefore not a claim that mounting performs no recovery actions. [mount616] The source audit is not a runtime crash test.",
