The seal read /boot/EFI/Linux/omarchy_linux-omarchy.efi. An edge install has linux-omarchy-bore, so the first nightly run stopped there. It now asks the running system which kernel package it booted and takes that UKI, and takes the command line from /proc/cmdline, since the boot entry, not the UKI, may be what holds it. The nightly's package report names the kernel the same way.
