+## Unveröffentlichte Änderungen nach v2.0.84

+- Permanente Providerfehler wie Real-Debrids `file_unavailable` markieren den ursprünglichen Quelllink nun unmittelbar als offline. Bei mehrdeutigen Unrestrict- oder Kontopoolfehlern wird ein zuvor als online erkannter Rapidgator-, DDownload- oder 1Fichier-Link einmal direkt beim Hoster nachgeprüft; nur ein bestätigtes Offline-Ergebnis beendet ihn dauerhaft.
+- Unter „Allgemein“ bestimmt „Wenn ein Quelllink offline geht“, ob nur der betroffene Mehrteil-Archivsatz oder das gesamte MDD-Paket übersprungen wird. Standard ist der Archivsatz. Die Zuordnung funktioniert auch dann, wenn Part 2 oder ein späterer RAR-, ZIP-, 7z- oder generischer Split-Part ausfällt.
+- Im Archivsatz-Modus laufen andere Folgen beziehungsweise unabhängige Dateien desselben Pakets weiter. Im Paketmodus werden alle noch offenen Dateien übersprungen. Bereits abgeschlossene Downloads bleiben in beiden Modi unverändert.
+- Verspätete Verfügbarkeitsantworten können einen bereits endgültig als offline markierten Eintrag nicht wieder auf online setzen. Die neue Nachprüfung wird pro Item gedrosselt, sodass mehrdeutige Providerfehler den Hoster nicht in einer schnellen Endlosschleife abfragen.
+- Entpack-, Passwort- und Nachbearbeitungslogik wurden nicht verändert; die vorhandene Dateinamen-Zuordnung für Mehrteilarchive wird ausschließlich für die Auswahl noch offener Download-Items wiederverwendet.

+- Unveröffentlichter Offline-Link-Fix: zwei vollständige Download-Manager-Läufe mit jeweils 274 von 274 erfolgreichen Tests. Die neuen Regressionen bestätigen den Wechsel eines zuvor online gemeldeten Rapidgator-Links auf offline, die direkte Behandlung von Real-Debrid-`file_unavailable`, den Schutz vor verspäteten Online-Antworten, die Gruppierung von `partN.rar`, `.rar`/`.rNN`, `.zip.NNN`, `.7z.NNN` und `.NNN` von jedem Split-Part aus sowie beide Überspring-Bereiche einschließlich Abbruch aktiver Geschwister und Erhalt fertiger Downloads. Nach der strikten Trennung von Download- und Entpacker-Gruppierung liefen die 9 betroffenen Regressionen und alle 84 Extractor-Tests erneut erfolgreich. Ein zusätzlicher vollständiger Lauf hatte ausschließlich im fachfremden Fake-Timer-Test für den globalen Speed-Limiter einen 10.000-Timer-Abbruch; dieser Test war in den beiden vorherigen Komplettläufen und direkt danach isoliert erfolgreich.
+- Vollständiger Clientlauf ohne die lokal nicht ausführbaren Symlink-Fixtures: 143 Testdateien erfolgreich, 1 optionale JVM-Testdatei übersprungen; 2.718 Tests erfolgreich und 4 übersprungen. Alle 84 unveränderten Extractor-Tests sind grün. Die Public-Release-Metadatendatei lief separat mit 22 von 24 erfolgreichen Tests; die zwei übrigen Fälle endeten unverändert bereits beim Anlegen ihrer Windows-Symlinks mit `EPERM`.
+- Nach dem Offline-Link-Fix erfolgreich: TypeScript, Main-Build, Renderer-Produktionsbuild, Node-Self-Check und alle 16 Backup-API-Tests. Die bekannte Vite-Warnung betrifft den rund 582 KiB großen Renderer-Chunk.
 
 - Kandidat für `v2.0.84`: 256 von 256 fokussierten Proxy-Segment-, Storage-, AppController-, Arbeitsordner- und Einstellungsansichtstests erfolgreich. Die Grenzwerttests bestätigen Minimum 2, Standard 32, Maximum 80 und die Begrenzung höherer Werte auf 80.
 - Vollständiger Clientlauf des `v2.0.84`-Kandidaten: 143 Testdateien erfolgreich, 1 optionale JVM-Testdatei übersprungen; 2.728 Tests erfolgreich und 4 übersprungen. Ausschließlich die zwei bekannten Windows-Symlink-Fixtures scheiterten mangels Berechtigung vor ihrer Produktassertion mit `EPERM`. Alle 265 Download-Manager- und 84 Extractor-Tests sind vollständig grün.
