- niri: index/config-tree rework, displays.md desk-profile rewrite,
  tips/action-reference/default-bindings refresh (26.04),
  generated keybindings.md (119 bindings)
- noctalia-shell.md: settings.toml lives in ~/.local/state, taskbar
  widget, v5 keybind table (Mod+D/Mod+V/Alt+Tab)
- handy.md: NEW; live nested store shape, fleet endpoint, known
  thinking-model empty-content breaker + verified cure
- log.md: DE redesign entry + pam_faillock sudo-lockout incident
