# Tasks: AppImage

Tasks by their numbers in the project-wide sequence, which continues across every spec.

- [x] T246 Register the AppImage file rather than the executable inside its mount, per FR-I01 and FR-I04 — done: `ServiceSpec::for_current_executable` takes `APPIMAGE` when the running executable is under `APPDIR`, so another AppImage's inherited variables are ignored; and the unit's `ExecStop` stops the daemon alone and waits for it, since stopping the whole unit at once unmounted the AppImage under the daemon and killed it with SIGBUS (R-104). Unit tested in `crates/service/src/lib.rs` against the variables the AppImage runtime sets, and in `crates/service/src/systemd.rs` for the `ExecStop`.
- [x] T247 Build and publish an AppImage for each Linux architecture, per FR-I02 and FR-I03 — done: `packaging/linux/appimage.sh`, run by GoReleaser after each full Linux build, bundles the Avahi client libraries and their license from the sysroot, sets the binary's RUNPATH, and packs it with appimagetool and the pinned runtime, which the cross image now carries; the release and checksums include `dist/*.AppImage`. Checked on Arch Linux and Ubuntu 22.04 (R-104); not unit tested, since it is a build script.
- [x] T248 Name the window on Linux so taskbars pair it with its desktop entry — done: the window's title is set to "Midi Harbor" at start, the desktop entry's `StartupWMClass` is `midi-harbor`, and the AppImage's `AppRun` runs the binary as `midi-harbor`, since the pinned libcosmic leaves the X11 class to `argv[0]` (R-104). Checked in XFCE on X11; not unit tested, since it is window-system wiring.
- [x] T254 Install the AppImage's desktop entry and icon for the user when the window runs from one, so a Wayland desktop finds its icon by application ID, per FR-I05 (R-109) — done: `desktop::integrate` runs before the window opens on Linux; `Exec` and `TryExec` name the AppImage file; nothing is written where a package provides the entry, or when the files already match. Unit tests cover the entry as the Desktop Entry Specification reads it, with a path holding a space, a dollar and a percent sign, and installing once and never over a package. Checked on XFCE: the entry passed `desktop-file-validate` and the taskbar gained the icon. Not seen on Wayland.
