release: v3.3.28

Reproduced from a real saved config: pendingQueue held 4 'preview' jobs (one
file across 4 hosters); the queue saved + restored correctly. But
_autoDeduplicateFromLog (runs at init after restore) removed jobs whose
fileName|hoster appeared ANYWHERE in the lifetime fileuploader.log, regardless
of status — so all 4 pending previews were deleted and the queue showed the
empty "Dateien hierhin ziehen" state. Looked update-specific only because the
server restarts on update; a plain restart did the same.

- New lib/queue-dedup.js (pure, dual CJS/window export like queue-prune.js):
  partitionRestoredJobsByLog drops ONLY 'done' jobs that match the log. Pending
  (preview/queued) and failed (error/aborted) jobs always survive — they're
  intentional queued work (often a deliberate re-upload of a previously
  uploaded file). Manual importUploadLog stays separate/explicit.
- renderer wires it in; index.html loads the module before app.js.
- Tests: 5 cases incl. the exact reproduced scenario (4 previews all in log ->
  0 removed). Full suite 162/162.

Verified against the user's real electron-config.json + fileuploader.log: old
logic removed 4/4 (empty queue), new logic removes 0/4 (queue preserved).

+// Startup queue auto-dedup logic. Extracted from renderer/app.js
+// _autoDeduplicateFromLog so the decision can be unit-tested without a DOM or
+// the renderer's module-level state.
+//
+// Loaded both as a CommonJS module (Node tests) and as a browser global
+// (renderer/app.js via index.html script tag) so a single implementation backs
+// runtime and tests — no drift.
+//
+// Behaviour: on launch the restored queue is compared against the lifetime
+// upload log. ONLY genuinely-completed ('done') jobs that also appear in the
+// log are dropped — that's pure decluttering of work that already finished.
+//
+// Pending jobs (preview / queued) and failed ones (error / aborted) are NEVER
+// dropped here, even if a same-name+hoster line exists in the log. Those are
+// work the user intentionally has queued (often a deliberate re-upload of a
+// file that was uploaded before). The old code filtered on log-presence alone,
+// regardless of status, so the ENTIRE restored queue vanished on the next
+// restart/update whenever the files had been uploaded previously — surfacing as
+// an empty "Dateien hierhin ziehen oder klicken" queue. Manual log import
+// (importUploadLog) stays separate and explicit for users who do want bulk
+// dedup of pending jobs.

 **Symptom:** "upload_result Seite hat keinen filecode (<leeres textarea>)" — nichtssagend; User dachte doodstream-Format geändert.
 **Root cause:** XFileSharing liefert den echten Grund im `st`-Feld (Error: duplicate / file too big / …). Code ignorierte `st` komplett und warf nur den leeren Body.
 **Regel:** Bei Hoster-Parsefehlern immer die Server-Statusfelder (st/msg/code) + Kontext (welcher CDN-Node, war filecode da) in die Fehlermeldung packen. Format-Struktur unverändert + leerer Inhalt = Backend-Ablehnung, kein Parsing-Bug.

+## 2026-05-25 — Queue leer nach Update: Auto-Dedup zu aggressiv (nicht Save/Restore)
+**Symptom:** Queue gestoppt, App-Update -> nach Neustart Queue leer ("Dateien hierhin ziehen"). User dachte Save/Restore kaputt.
+**Root cause:** Queue WIRD korrekt gespeichert (pendingQueue) + restored. ABER `_autoDeduplicateFromLog` (läuft bei init nach restore) entfernte Jobs per `fileName|hoster`-Match gegen das GESAMTE Lifetime-fileuploader.log — UNABHÄNGIG vom Status. Pending 'preview'-Jobs, deren Datei früher mal hochgeladen wurde, flogen alle raus -> komplette Queue weg. "Update-spezifisch" nur weil der Server-App nur beim Update neustartet (normaler Restart hätte dasselbe getan).
+**Verifiziert:** Reale electron-config.json: 4 preview-Jobs, alle 4 Keys im Log -> alte Logik entfernt 4/4. Neue Logik (nur status==='done' droppen) entfernt 0/4.
+**Regel:** Auto-Cleanup/Dedup darf NIE pending/actionable User-Arbeit löschen. Nur genuin abgeschlossene ('done') Jobs decluttern. Lifetime-Logs sind Historie, nicht Session-Fortschritt — nicht als "schon erledigt"-Quelle für pending Jobs missbrauchen.
+**Wie anwenden:** Bei jeder Filter/Remove-Logik auf User-State: nach Status gaten, nicht nur nach Identitäts-Match gegen historische Daten.
