"""Wegwerfskript: DirSize + MD5 direkt gegen die NAS testen.

Finale Befunde:
  DirSize: start v2 (path als plain string ODER JSON-Array), status v1 (0ms delay)
  MD5:     start v2, status v1 (0ms delay, ONE-SHOT)

DirSize status-Response Felder:
  finished: bool
  num_dir:  int   (Anzahl Unterordner)
  num_file: int   (Anzahl Dateien)
  total_size: int (Gesamtgroesse in Bytes)

MD5 status-Response Felder:
  finished: bool
  md5:      str   (Hex-String, 32 Zeichen)

Ausfuehren: uv run python test_dirsize_md5.py
