@@ -109,3 +109,12 @@ Moduł web pokazuje stan do pierwszej odtworzonej klatki, umożliwia anulowanie
 **Koszt i zakres:** tryb jest domyślnie wyłączony w nowych konfiguracjach. Włączenie normalizuje kanał do H264 1920×1080 50 kl./s, CRF20 z maksimum 12 Mb/s, AAC 48 kHz stereo. Nie zachowuje 4K, HDR, wielokanałowego audio, dodatkowych ścieżek ani napisów. Wymaga programowego kodowania; pomiary dotyczą konkretnego testu. Wyłączenie przywraca dotychczasowy odbiór. Nie zmienia konfiguracji Jellyfina, wrapperów, profili dekodera ani OSCam.
 
 Weryfikacja: `Tests` obejmuje izolację użytkowników/urządzeń, uprawnienia, migrację kanałów i wcześniejsze mechanizmy streamu, katalog języków, zegar TS i ograniczoną pamięć przy symulowanej sześciogodzinnej awarii. `test-web-bridge.cjs` sprawdza web bez kont produkcyjnych. `experiments/run-continuity-e2e.py` uruchamia izolowany harness z prawdziwym FFmpeg, dwoma językami i sterowanym źródłem syntetycznym; opcja `--long` utrzymuje awarię 75 s, sprawdza odzyskanie obrazu, rygorystyczny odczyt AV i wszystkie 12 plansz. Nie jest to test fizycznego Android TV ani produkcyjnej sesji Jellyfina. Należy jawnie odróżnić przygotowany kandydat od wersji aktywnej na serwerze.
+
+
+### 7.0.13 — zachowanie rozdzielczości źródła
+
+Na żądanie użytkownika usunięto sztywny limit Full HD z domyślnego trybu plansz. `PreserveSourceResolution` domyślnie wynosi true: filtr producenta nie skaluje ani nie zmienia SAR kanału. Rozdzielczość początkowej planszy nie jest już wpisywana jako rozmiar źródła do natywnej negocjacji Jellyfina. Profile urządzeń mogą nadal ograniczać wyjście zgodnie z możliwościami klienta i jego ustawieniami jakości. Nie ustawiono sztywnego limitu szerokości/wysokości producenta; maksymalny segment zwiększono do 32 MiB, a limit przepływności kodera do 48 Mb/s. Kodek i dźwięk pozostają H264 8-bit, 50 kl./s i AAC stereo — ta zmiana nie dodaje zachowania HDR, oryginalnego kodeka, ścieżek audio ani napisów.
+
+Izolowana próba z rzeczywistym FFmpeg potwierdziła przejścia plansza → 720×576, 1280×720, 1920×1080, 2560×1440 i 3840×2160. Odczytano rzeczywiste wymiary zdekodowanych klatek zarówno z MPEG-TS, jak i HLS fMP4, a dla SD również SAR16:15. To test syntetyczny o małej zmienności obrazu, nie dowód wydajności każdego kanału UHD ani test fizycznej aplikacji. Dodatkowa próba z zachowaniem 720p potwierdziła 75 sekund awarii, właściwe języki plansz i odzyskanie obrazu bez ponownego otwierania klienta. Testy wykorzystują również natywny StreamBuilder Jellyfina12.2 do sprawdzenia limitów urządzeń od SD do UHD.
+
+7.0.13 jest kandydatem do odrębnego zatwierdzenia; nie nadpisuje automatycznie wdrożonej7.0.11. Wcześniejsza zgoda dotyczyła tylko nocnego Jellytel. Nie aktywować starego kandydata7.0.12 ograniczonego do Full HD.
