The T6 Linux app artifact is a versioned tarball of a nix-closure-backed bundle directory (store-rpathed binaries via the devenv.lock-pinned GTK closure + cc-wrapper, .desktop inside), not AppImage/nix bundle/wails3 package; no-nix-store end-user distribution is the A5 installer follow-up’s concern, which wraps this same bundle dir
