OneDrive Version History practice — expected result

Use a disposable OneDrive practice file. The two downloaded text files
are example contents, not an existing OneDrive version history.

Earlier approved content: S-301 100 + S-302 90 + S-303 120 + S-304 110
                      = 420 USD.
Later accidental content: S-302 becomes 150; total becomes 480 USD.

After restoring the confirmed earlier version:
- The current file again shows S-302 = 90 and approved total = 420 USD.
- OneDrive's Version History retains the previously current version as an
  older version, according to Microsoft Support.

If no earlier version appears, stop. Do not restore a production file based
only on a similar filename or an assumed timestamp. Check account and
organization versioning settings before continuing.
