 ## Distribution
 
-Desktop installers move to version-less artifact names following the CLI bundle convention — `penguin-desktop-darwin-{arm64,x64}.dmg` / `.zip`, `penguin-desktop-win32-x64.exe`, `penguin-desktop-linux-x64.AppImage` / `.deb` — with the version carried by the Release tag and `SHA256SUMS.desktop`. The OSS mirror job now mirrors all seven installers plus `SHA256SUMS.desktop` into the immutable per-tag prefix, verified as a set through `SHA256SUMS.desktop`; the CLI bundles' canonical manifest is unchanged.
