fix: stop dropping a song's favorite state - #213
Conversation
Favorites moved out of interactions server-side, so the play-registration response no longer carries a liked flag. Parsing the absent field yielded false, which was then written over the song's real favorite state — and persisted to download metadata for downloaded songs.

Every other model already reads `favorite`; Song alone still read `liked`, which Koel keeps only as a backwards-compatibility alias. Dropping that alias would have parsed the whole library as unfavorited, silently — an absent key is indistinguishable from an explicit false here.

- Around line 70-90: Update the test around Song.fromJson to use conflicting
values: keep favorite true and set the legacy liked key to false, asserting the
parsed liked value remains true; add the inverse case with favorite false and
liked true, asserting false is preserved to verify favorite field precedence.

Two ways a song's favorite state gets dropped, both from the app tracking a field the server has moved on from.
A play registration unfavorites the song
Open the Now Playing sheet on a favorited song and the star is filled. Let playback pass a quarter of the way through, close the sheet and reopen it — the star is empty. The server still has the song favorited; only the app's copy is wrong.
Koel moved favorites out of
interactionsinto their own table (2025_07_18_105237_favorites.php, which dropsinteractions.liked), soInteractionResourcereturns onlytype,id,song_idandplay_count.Interaction.fromJsonstill readjson['liked'], which now resolves tofalse, and_registerPlayCountwrote that over the song's real favorite state — then handed it topersistMetadataIfNeeded, so downloaded songs kept the wrong value across restarts.The registration fires at 25% of the track, which is why it looks like reopening the sheet causes it. Whether you actually see it is a race:
Song.merge()copieslikedfrom any payload, so a favorites/search/overview fetch, or the five-minute download sync, will quietly repair the damage before you look. That's why it hits some songs and not others.Song reads a legacy field name
Album,Artist,PodcastandRadioStationall readfavorite.Songalone still readliked, which Koel sends only as a backwards-compatibility alias next to the real one. Since an absent key is indistinguishable from an explicitfalsehere, dropping that alias server-side would have parsed the entire library as unfavorited without a single error.Song now prefers
