The live-update guard (guard.py) only matches mesa/hyprland (the 2026-06-07 live-swap class) — it never checks /boot, kernel, initramfs, or mkinitcpio exit. No post-upgrade /boot assertion exists. An interrupted kernel transaction slips straight through. +- Add a post-upgrade /boot assertion: after a transaction touching linux/linux-*, confirm vmlinuz-* + initramfs-*.img present and mkinitcpio exit 0; refuse to end the run (or page Craig) otherwise. Would have caught this. +- Sanoid-vs-actual dataset drift: configure_zfs_snapshots configures zroot/var/log + zroot/var/lib/pacman as separate datasets; velox's actual layout has neither separate (/var/log sits inside zroot/var). Reconcile. +- Confirm the pre-pacman snapshot hook is actually installed + firing on velox (it should be — it's what makes recovery possible). + +** TODO [#C] Add inetutils to install base :feature:solo:quick:network: +TRAMP's /ftp: method (ange-ftp) shells out to a command-line ftp client; Arch ships none by default. GNU inetutils provides =/usr/bin/ftp=. Craig's dirvish config has an FTP quick-access entry (phone FTP server), so it's a config dependency. Installed manually on ratio 2026-07-14; velox needs it once it boots. Add to the install base so future machines get it for free; verify via VM test.
