QuellCode/CentronERP war nur als Gitlink (Submodul-Referenz auf 79c1142) getrackt, ohne .gitmodules und ohne erreichbares Remote. Der Untersuchungsgegenstand der Versuchsreihe war damit nicht reproduzierbar gesichert: Ein Klon haette ein leeres Verzeichnis erhalten, und die Belege der 3.287 Anforderungen waeren nicht ueberpruefbar gewesen. Umstellung: - Historie nach c:\DEV\CentronERP_git_snapshot_79c1142 ausgelagert (vollstaendig lesbar, enthaelt 79c1142 und Vorgaenger 89ccfd6) - Gitlink aus dem Index entfernt - Dateiinhalt aufgenommen: 24.557 Dateien, rund 333 MB Die verschachtelte .gitignore der Codebasis gilt weiter, Build-Artefakte bleiben ausgeschlossen.
