 | `install/config/gpg.sh` copied GnuPG config and restarted dirmngr. | Package-owned `etc/gnupg/dirmngr.conf`; live dirmngr restart removed. | package | `cat etc/gnupg/dirmngr.conf` |
 | `install/config/pi.sh` activated Pi theme. | No direct install path remains; theme changes still run Pi retint hooks when applicable. | intentionally removed / review | `rg 'omarchy-theme-set-pi' bin install migrations` |
 | `install/login/all.sh` mixed default keyring with SDDM/login manager work. | `install/login/system.sh` owns SDDM/hibernation/limine; `install/login/default-keyring.sh` runs through user setup and is idempotent. | split | `cat install/login/system.sh install/login/default-keyring.sh` |
-| `install/login/sddm.sh` wrote static SDDM config, autologin, PAM tweaks, and enabled service. | Static `10-wayland.conf` and `10-theme.conf` live under `etc/sddm.conf.d`; `sddm.sh` manages autologin and remaining live file copies/PAM tweaks; service enable moved to `enable-services.sh`. | package + system | `cat etc/sddm.conf.d/*.conf install/login/sddm.sh install/config/enable-services.sh` |
+| `install/login/sddm.sh` wrote/copied static SDDM config/assets, autologin, PAM tweaks, and enabled service. | Static SDDM drop-ins live under `etc/sddm.conf.d`; theme/session assets are package-owned; `sddm.sh` now manages only autologin, legacy `hyprland.conf` cleanup, and PAM tweaks; service enable moved to `enable-services.sh`. | package + system | `cat etc/sddm.conf.d/*.conf install/login/sddm.sh install/config/enable-services.sh` |
 | `install/post-install/allow-reboot.sh` created online reboot sudoers. | Kept, now also grants one-time cleanup; `omarchy-first-run` calls `cleanup-reboot-sudoers.sh` with `sudo -n` so future users are not prompted. | online post-install + first-run cleanup | `cat install/post-install/allow-reboot.sh install/first-run/cleanup-reboot-sudoers.sh` |
