1. Cookie 'Zwecke' false positive: added 'um...zu', 'dienen', 'helfen', 'ermöglichen' patterns — catches purpose descriptions without 'Zweck' 2. Kurzhinweis: added empty all_checks for short documents (<200 words) 3. Bezeichnungsfeld: placeholder shows 'Version / Stand' for typed docs, 'Dokumentname' for 'Sonstiges' 4. DocCheckTab state persistence: entries + results survive navigation 5. DocCheck history: saves each check with date, doc count, findings 6. History display: 'Letzte Pruefungen' section at bottom of tab 7. ChecklistView: shows 'X von Y Pruefpunkten bestanden' per document 8. Results persist in localStorage across page navigation Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
