`plus` meant "add to the queue", "add to a playlist", "make a new playlist" and "you do not own this" -- the first two adjacent in the same context menu, so two neighbouring items were the same glyph doing different things. `list` meant the queue (the button that opens it), the Playlists destination, and adding to the queue in `queue-panel` alone. Two icons carrying seven meanings is not a vocabulary, and nothing catches it: a wrong-but-real icon renders perfectly. `utils/icon-language.ts` is the table, beside `library-status.ts` as the issue suggested. The rule it is built on is that an icon names the **noun** it acts on, not the verb: "add to queue" and "add to playlist" are one verb on two nouns, so the noun is what differs -- which is why adding to a playlist wears the Playlists destination's own icon, and why the queue took `bars-staggered` and stopped wearing Playlists'. `plus` keeps the one meaning it is unambiguous about, making something that is not there yet, which covers New Playlist and the drop zones. `bars-staggered` is the only new glyph, vendored through names.txt and fetch-icons.mjs after confirming it is in Font Awesome **Free** 7.3.1. Two things this found rather than changed: - The request toggle's outline/solid pair was already in the app and already right -- `explore-album-details`'s "Request this" button has used `regular/bookmark` -> `solid/bookmark` since it was written -- while the badge forty pixels away showed a **plus** for the same state. That is `utils/library-status.ts`'s fault one layer down: it made the two surfaces agree on what wanting *means* and left them disagreeing on what it looks like. - `explore-artist-details`'s Follow button was `bookmark-check`, which is Font Awesome **Pro** and has never been bundled, so it has drawn the missing-icon fallback -- a circled question mark -- for every followed artist since it was written. `requested-badge.spec.ts` was written for exactly this bug on the album button and says so in its docstring; this is the same bug one component over, still live, because `offline-icons.spec.ts` sweeps `__yjIconMisses` and no spec had ever followed an artist. So the test does what reaching the state cannot. `icon-language.test.ts` reads every `src/**/*.ts` as raw text and fails on a governed name written outside the table, and separately asserts every `ICON_*` is a *bundled* name -- which is what makes a Pro name a failing test rather than a runtime report from a state something has to reach first. Its first assertion is that it read any source at all, because a sweep over an empty glob passes. `chrome.test.ts` asserted `['check', 'bookmark', 'plus']` and so pinned the badge's glyphs against the vocabulary they were meant to follow; it names them from the table now, and keeps the assertion that the three differ, which is the property the states actually need. Downloads keeps the solid bookmark on purpose. That is one word twice, not two words: the badge says the entity is on your list and the nav item is that list. Closes #34

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
