 * On large libraries (reported with ~200,000 tracks on Navidrome), background library sync could lock up database writes for minutes at a time — playback history, ratings and other saves piled up waiting behind it.
 * Root cause: the track id-remap step ran a database lookup that couldn't use its indexes and scanned the entire track table once per incoming track, so the cost grew with the square of the library size. The lookup now uses the proper indexes, bringing it back to a fast, near-instant operation.
 
+### Windows media controls showed "Unknown application"
+
+* On Windows, the system media controls (the Quick Settings media tile, the lock screen and third-party media flyouts) labelled playback as "Unknown application" with no icon. The app now registers an explicit application identity at startup so Windows shows "Psysonic" and its icon as the playback source.
