The floor on the art's height passed locally at 114 and failed in CI at 64. Both numbers are honest and neither is about this change: the e2e app is long-lived, so a job staged by an earlier spec is still on screen, and the volume control renders here where it does not on Android. Both are chrome above and below the view, and both move the leftover. So the claim is stated as what the reflow does rather than as what it measures -- in a row the art is bounded by the row's height and fills it, where in a column it is the leftover after the names. That is the mechanism behind 53px to 143px, and it fails on the old build with "there is no row to fill". The device numbers stay on #51, which is the only tier that can honestly produce them. This is the second draft of that assertion to be thrown away; the first compared the art against the column's leftover and passed on the defect, because the subtraction goes negative exactly when the names are taller than the art. Also stops the arrangement wait from requiring the row to exist, so reverting the component to check that these tests bite still produces the crop measurements -- 263x39, 358x315, 300x36 -- rather than eight timeouts. 5 of 8 fail on the build before this change.
YellowJacket
Music how it was meant to bee.
YellowJacket is a fast, cross-platform desktop music player for your local collection. It plays your files, keeps your library tidy, and helps you discover and organize your music — all in a clean, responsive interface. No accounts, no streaming, no telemetry: just your music on your machine.
Runs on Linux, macOS, and Windows.
Features
Play your music
- Plays MP3, FLAC, OGG Vorbis, and WAV
- Play, pause, seek, and volume control with a mute toggle
- Gapless, glitch-free seeking backed by a read-ahead buffer
- A queue you can add to, reorder, and shuffle, with play-next support
- Shuffle and repeat (off / all / one)
- Picks up right where you left off — remembers your track, position, and volume between sessions
- Media-key and MPRIS support on Linux, so your desktop's playback controls just work
Keep your library organized
- Point it at your music folders and it scans them automatically
- Reads tags and embedded cover art, and de-duplicates artwork so it isn't stored twice
- Incremental sync — only new or changed files get reprocessed, and deleted files are cleaned up
- Browse by album, artist, or genre, or search across everything
- Mark favorites and see what you've been listening to with play history
- Edit track tags directly when something's off
Playlists
- Create playlists, drag tracks in, and reorder them
- Smart playlists that build themselves from rules (by genre, rating, play count, and more)
- Pin a default playlist and spot duplicate tracks at a glance
Discover and clean up (powered by MusicBrainz)
- Explore — browse artists, releases, and genres from the MusicBrainz catalog, not just what's already in your library
- Auto-tag — match your files against MusicBrainz to fill in correct artist, album, and track metadata, with a review step before anything is written
- Lyrics search — find a track by a line you remember

Building from source
YellowJacket is built with Go and a Lit/TypeScript frontend, bridged by the Wails framework.
Prerequisites
| Tool | Version |
|---|---|
| Go | 1.25+ |
| Node.js | 22+ |
| pnpm | 10+ |
| Wails CLI | v3 — vendored, no install needed (go tool wails3) |
The Wails v3 CLI resolves from the tool block in go.mod, so there is nothing
to install globally; make setup fetches it with the rest of the tooling.
On Linux, install the system libraries Wails needs. v3 builds against GTK4 + WebKitGTK 6.0 by default:
sudo apt-get install libasound2-dev libgtk-4-dev libwebkitgtk-6.0-dev # Debian/Ubuntu
sudo pacman -S alsa-lib gtk4 webkitgtk-6.0 # Arch
A machine without webkitgtk-6.0 can still build with -tags gtk3 against the
older WebKit2GTK 4.1 stack, but that is an escape hatch, not what CI or a
release builds.
macOS and Windows need no extra system packages. Run go tool wails3 doctor to
check your environment.
Build
make setup # install tooling and git hooks
make dev # run with hot-reload
make build-prod # produce a release binary
