- Linux app id dev.foxyz.starsync, binary starsync; Windows starsync.exe, company foxyz; server starsync-server; Dart package starsync; archives starsync-<ver>-*. - 1.2.x compatibility: watch_together and watch-together-server launchers (Linux) / copies (Windows) in the archive; the updater accepts both names and relaunches the new binary; update.sh/.bat use whichever server exists. - First start copies (never moves) the old support folder and this app's Hive boxes out of ~/Documents into <support>/hive; a marker makes it run once; AppDirs is a port; settings schema version with ordered migrations. - Launcher entry dev.foxyz.starsync.desktop; the old one removed. - Repository name and URLs unchanged.
