+## Wdrożenie 7.0.8 i spójne limity startu — 13.10.2026, 09:05 CEST
+
+Produkcja CT100191 używa teraz **7.0.8.0**. Wcześniejsza informacja o kandydacie niewdrożonym powyżej opisuje poprzedni etap. Backend zaliczył 83 kontrole, build bez błędów i ostrzeżeń. Relay daje łącznie 20 s na nagłówki i pierwszy fragment TS (gotowość 21 s), a po rozpoczęciu nadal wykrywa 8 s ciszy. Cała próba rozpoznania pozostaje ograniczona do 25 s, więc późny start skraca pozostały czas analizy. Pierwsze odrzucenie próbki przez ffprobe uruchamia najwyżej jedną większą analizę na tym samym połączeniu; anulowania i innych błędów procesu nie ponawiamy.
+
+Moduł webowy wtyczki czeka do 45 s na start obrazu (25 s metadane + 20 s uruchomienie odtwarzacza). Przycisk powrotu i Escape pozostają dostępne. Test potwierdził oczekiwanie przy 35 s i powrót przy 45,001 s. Zaktualizowano wyłącznie istniejący `decoder-channel-playback.js`; w otwartych przeglądarkach wymagane Ctrl+F5. Natywny Android TV ma własny interfejs i własne limity klienta.
+
+Aktualny `deploy-plugin-only.py` wymaga `--maintenance-approved --dll PATH --expected-sha256 HASH`. Nie czyta bazy ani kluczy API. Po backupie sprawdza publiczny health, świeży log załadowania dokładnej wersji, manifest i hash DLL; w razie błędu przywraca poprzednią wtyczkę. Pierwsza próba zbyt wcześnie odrzuciła odpowiedź podczas rozruchu i została cofnięta na 7.0.7. Kontrola gotowości została poprawiona i przetestowana; ponowne wdrożenie przeszło. Backup DLL/manifestu i poprzedniego JS: `/var/lib/jellyfin/decoder-plugin-backups/plugin-only-20261013T070224088507Z`.
+
+Końcowo potwierdzono aktywną usługę 12.2.0, manifest Active7.0.8, log załadowania nowej DLL, hash serwowanego JS, HTTP200 strony dodatku oraz 0 strumieni, 0 FFmpeg i 0 tymczasowych próbek. Hashe ustawień serwera, wrapperów FFmpeg i plików index/config Web pozostały bez zmian. Raport: `deployment-7.0.8-20261013.json`. Po wdrożeniu nie wykonano jeszcze odtwarzania na zalogowanym kliencie: przeglądarka testowa wymaga SSO, a test Android TV czeka na użytkownika. Ostatnia wcześniejsza próba Pulsu o 08:42 CEST nadal nie rozpoznała AV po 20 s; zmiana limitów nie jest dowodem naprawienia odkodowania w odbiorniku.
