 ### Fixed
+- tuigreet boot error: removed invalid `--numlock` flag from greetd config (not a valid tuigreet parameter). Replaced X11-only `numlockx on` in Hyprland with native `numlock_by_default = true` in the `input` section (2026-06-01).
 - hypridle SEGV crash loop (ADR N/A, hotfix): sdbus-cpp 2.3.0 had an ABI incompatibility causing hypridle to SIGSEGV in `libsdbus-c++.so.2` `registerSignalHandler`. Fixed by upgrading sdbus-cpp from 2.3.0-1 to 2.3.1-1 (Arch upstream, pulled ahead of Manjaro mirror sync). Also resolves latent ABI issues for hyprlock and xdg-desktop-portal-hyprland (2026-05-22).
