Qualitäts-Review-Befund (a): Alle 6 part/part-of-Aufteilungen hatten Code vollständig übernommen (Zeilen-Multiset-Vergleich Original vs. heutiger Stand: keine Code-Zeile verloren, keine hinzugefügt), ABER erklärende Kommentare über den Klassen gingen verloren (24 Blöcke, u. a. die HTML-Subset-Doku über _MatrixHtmlText, die Selbst-Aussperr-Warnung über updatePowerLevelsSafely, TURN-Verbrauchskarte, PDF-Cache/Viewer-Doku). Alle an den richtigen Klassen wiederhergestellt; reine Trennlinien und ALL-CAPS-Abschnittslabels bewusst nicht (Gott-Datei-Navigation, durch die neuen Dateinamen ersetzt).
