A singleton default naming code.desktop left the live ISO with no text handler — GIO skips missing .desktop files and offers nothing. Prefer vscode when present, then org.gnome.TextEditor.desktop. Live also gains mpv (video defaults had the same hole; free via the template pin). checks.live-baseline-apps now requires every Default Applications key to resolve to a present .desktop on live (HM + system path) and on the default template install. Proved to fail on a vscode-only text/plain. Verified: V2 (live-baseline-apps green + prove-to-fail); V0 flake check.

# Default applications (xdg mimeapps.list) — without this, "open a

# deleting an app from the template suite (or never uncommenting the
