Research direction

Reproduce the failure by modifying a file in /boot/, rebooting, and selecting an option through "Show OS boot menu". Trace the boot-menu path and its GPG verification failure handling; done means the verification error is shown instead of returning silently to the previous menu, while the default boot option continues to work.
