On the reference device every context menu in the app is clipped, and the two halves of that are structural rather than incidental. Chrome 113 has no Popover API, so wa-popup takes its own documented fallback and positions with strategy: "fixed"; .main-panel carries contain: layout style paint, and paint containment clips fixed descendants. Measured at 424x439 before any of this: the main panel spans 0-318, the open menu spanned 191-401, and three of its seven items were cut off with no way to reach them. Rows were 29px against a 44px floor. menu-surface is one element with two presentations -- a wa-popup above 600px, a wa-dialog bottom sheet below it -- so the host keeps rendering the panel it always rendered and ContextMenuController keeps driving .active and .anchor as though it were talking to a popup. showModal() is Chrome 37 and uses the real top layer, so the sheet is immune by construction rather than by styling. Four things needed measuring on the hardware rather than reading. "A dialog escapes containment" was the premise and was untested here: every other dialog in this app is mounted in index.html, outside .main-panel. A probe dialog appended to track-list's shadow root paints to y=439, over the mini player and the tab bar. A native dialog's UA stylesheet centres it and caps its width, which drew a 354px panel in the middle of a 424px screen -- so four declarations in this component are pure undoing. wa-dialog focuses [autofocus] or itself on the frame after showModal(), and it cannot see our first menu item to prefer it: the panel is slotted, so its own querySelector stops at the <slot>. A longer retry budget does not fix that, because the first attempt succeeds and is then overwritten -- hence menu-shown and MenuKeyboard.refocus(). The budget became time-based anyway, since what is being waited for is another component's animation. And a dismissal has to travel back: wa-dialog closes itself on Escape, which would leave the controller believing the menu is open. The failure mode there is not a stuck sheet but the *next* long-press doing nothing, which reads as the gesture breaking.

- 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

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
