1440-1442: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick winDo not skip synchronization for an empty remote playlist.
When the successful response contains no songs, this return runs before
database.clearPlaylist(playlistId). After the final remote song is deleted, its remote-backed local entry remains. Let the empty result reach the rebuild transaction so it removes remote-backed entries and preserves entries withsetVideoId == null.Proposed fix

Added Went with the conservative branch here on purpose: an ambiguous empty result staying unsynced for one cycle is a much cheaper mistake than wiping out a whole playlist based on a read we can't actually verify. Added 4 unit tests covering the combinations (confirmed non-zero count, confirmed zero count, missing count, non-empty fetch). |

Problem
Songs deleted from a playlist in YouTube Music reappear at the end of that playlist in Metrolist after auto-sync, instead of disappearing.
Cause
In
executeSyncPlaylist(SyncUtils.kt), every local song absent from the remote fetch was unconditionally re-appended at the tail (preservedSongs,position = songs.size + index) after clearing and repopulating from remote. That set is exactly the songs deleted on YouTube, so remote deletions never propagated and the sync never converged (full rewrite on every cycle).Solution
setVideoId == null, e.g. added offline in Metrolist). Songs with a knownsetVideoIdthat are missing from remote are treated as intentionally deleted and dropped.development_guide.md).Testing
