The same addressing rules are applied to the parity disks because
they are used as data disks during recovery operations.

2bac137218 Remove the requirement to snapshot content files 
The new content file format now includes metadata for previous versions
of files. This allows the fix command to access historical file data from
snapshots as needed, ensuring recovery even if the live filesystem has
changed or the file was deleted during a sync.

f413e96ec4 Track deallocated files in the content file for parity recovery 
Add a new 'dealloc' list per disk to record files that were removed
or modified during a scan. This list is saved in the content file
(new format version SNAPCNT4) so that past parity contributions of
those files can be imported from previous snapshots.

85ede49477 Sync no longer requires clearing the past hash 
It no longer assumes past hashes are valid if even a single unsynced
block exists, which indicates a previous sync was interrupted.

While this makes syncing slower after an interruption, it preserves the
past hash in the content file, enabling a more reliable fix if a
disk fails following an incomplete sync.

This ensures the --import option remains functional even after an
interrupted sync.
