### Bundled Bun runtime {#bundled-bun-runtime}
Every package includes an unmodified copy of Bun 1.3.5 that runs the command-line launcher. Bun is MIT licensed and statically links JavaScriptCore under LGPL 2.0 and TinyCC under LGPL 2.1. The license texts, third-party notices, and a `SOURCE.md` describing the corresponding source ship inside the app under `resources/bun/licenses` (`SubMiner.app/Contents/Resources/bun/licenses` on macOS). Each GitHub release also publishes `bun-v1.3.5-source.tar.gz` with the matching Bun, WebKit, and dependency sources and instructions for rebuilding Bun against a modified JavaScriptCore.

The `Finish setup` button requires a config file and at least one Yomitan dictionary. The launcher is optional and never blocks setup completion.
On Linux and macOS, setup selects a writable directory already on your terminal `PATH`. If it cannot find one, it creates `~/.local/bin` and shows the `export PATH=...` command to run. Add that command to your shell configuration yourself if you want it in future terminals. Setup never edits shell configuration files. On Windows, setup adds only the wrapper directory to the user `PATH`. Setup stores a custom app location so the wrapper can find an AppImage or app bundle outside the usual install directories.

SubMiner verifies AppImage, launcher, and Linux support-asset downloads against `SHA256SUMS.txt`.

If the binary is in a protected path, SubMiner shows the exact command to run rather than elevating itself.

The tray "Check for Updates" entry installs the new app automatically on Linux, macOS, and Windows. Current `subminer` wrappers remain small bootstraps that locate the installed app and its private runtime. On Linux the updater replaces the running `.AppImage` in place via `electron-updater` and refreshes managed support assets from `subminer-assets.tar.gz`. The next launcher invocation detects the changed AppImage fingerprint and prepares the matching Bun and CLI cache before running the command. App startup also refreshes this payload and migrates recognized writable legacy launchers, including the launcher path an update deferred. AppImages managed by a system package, for example the AUR `/opt/SubMiner/SubMiner.AppImage`, are skipped so the package manager stays in charge.
`subminer -u` also performs the AppImage, launcher, and managed support-asset updates directly from the launcher process, which is useful when SubMiner is not currently running.
On Linux, `subminer -u` updates the AppImage and managed support assets directly, even when the app is not running. The launcher cache refreshes when the app fingerprint changes. AUR installs remain under package-manager control and should be updated through the package manager.

## Manual launcher install
The `subminer` launcher uses a [Bun](https://bun.sh) shebang, so Bun must be installed. First-run setup can handle this automatically, but if you prefer to do it yourself:
Current launcher downloads use Bun included in the SubMiner app. The wrapper searches normal install locations and honors `SUBMINER_BINARY_PATH`; Linux also honors `SUBMINER_APPIMAGE_PATH`.

Download `subminer.cmd` from GitHub Releases and place it in a directory on your user `PATH`. It finds the installed app in the normal per-user or Program Files location. Set `SUBMINER_BINARY_PATH` if you use a portable or custom install.
Launchers installed before the private-runtime change may still be bundled JavaScript with a Bun shebang. Those old files need system Bun until a current app startup migrates a recognized writable launcher, or until you replace one with the current release wrapper.
