`make sandbox`, `make dev`, `make build-dev` and `make build-prod` all died with "/bin/sh: wails3: command not found". `wails3 dev` and `wails3 task` are supervisors: they run the scaffold's Taskfile tree, which invokes `wails3` by bare name in 54 places across four files. The CLI is a vendored Go tool by design (plan 009, D3 — a global install would be this build's first undeclared dependency), so that name did not exist. scripts/toolbin/wails3 execs `go tool wails3`, and the Makefile prepends that directory only for the targets that start a supervisor. Rewriting 54 scaffold call sites would be churn to redo on every scaffold refresh; nothing global is installed either way. The shim does not cd. The first version did, to be sure `go tool` found the module — it does not need to — and that silently discarded the `dir:` a task had set, so generate:icons failed with "open appicon.png: no such file or directory" against a file that was there. Three things the build path needed once it got that far: - `frontend/package.json` gains `build:dev`, which build:frontend runs under DEV=true and which did not exist. - Vite binds 127.0.0.1. It defaulted to `localhost`, which resolves to `[::1]` only here, while wails3 dev's asset proxy dials IPv4 — so the first request for the dev server was refused and the first paint raced a retry. Zero proxy errors after. - The icons and the .desktop file are generated on every build. icons.icns/icon.ico are deterministic from our appicon.png (verified by regenerating), so the regenerated pair is committed and the churn ends; .task/ and the .desktop file are ignored. Also corrects a claim: build-prod strips and trims but does **not** UPX-compress — that was v2's `-upx` flag. Phase 1 recorded UPX as still working, but neither build target had been run.

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 | v2 (go install github.com/wailsapp/wails/v2/cmd/wails@latest) |
On Linux, install the system libraries Wails needs:
sudo apt-get install libasound2-dev libgtk-3-dev libwebkit2gtk-4.1-dev
macOS and Windows need no extra system packages. Run wails doctor to check your
environment.
