 ### Later (speculative or research-shaped)
 
-- **Declarative-state migration.** Move the bits of `state.json` that don't actually need runtime mutability (theme, font, isLightMode) into NixOS / home-manager options, leaving only genuinely runtime-only state behind. Reduces the "two sources of truth" surface.
+- **Declarative-state migration: Batch 2 (Toggles & Layout).** Move the remaining configuration fields from `state.json` (panelPosition, hyprland gaps/borders, system toggles) into NixOS / home-manager options. Finalizes the separation between genuinely runtime-only state (e.g. `welcome_done`) and declarative configuration.
 - **Rolling vs pinned channel choice in the installer.** Today the generated flake pins `nomarchy` to a rev. Offer a "rolling" option that follows `main` and a `nomarchy-rollback` helper for stuck rebuilds.
 - **Theme creation wizard.** A `nomarchy-theme-new` script that scaffolds a new palette from a base16 hex set (or by sampling a wallpaper), runs `nomarchy-themes-prebuild`, and opens a PR template.
 - **CI matrix on Forgejo Actions.** On every push: `nix flake check`, build `nomarchy-installer`, `nomarchy-live`, `default`. On tag: publish ISOs as release artefacts.

+- _2026-05-31_ — **Declarative-state migration: Batch 1 (Theme & Font).** Moved the primary source of truth for `theme` and `fonts.monospace` from `state.json` to pure Nix options in `home.nix` (and `system.nix` for theme). The `nomarchy.theme` and `nomarchy.fonts.monospace` options now default to schema values and are the declarative authorities. Runtime scripts (`nomarchy-theme-set`, `nomarchy-font-set`) still update `state.json` for instant session-local feedback and as a "seed" for future rebuilds, but now notify the user that these changes are temporary until added to their Nix configuration.
+- _2026-05-31_ — **Declarative monitor scaling.** Replaced static `monitors.conf` with a Nix-generated file driven by `nomarchy.hyprland.scale` (default `"auto"`). Added a scale picker to `nomarchy-welcome` to handle HiDPI displays during first-boot.
 - _2026-05-31_ — **Calendar app shipped.** Added `calcurse` (TUI calendar) to the core `features` module and wired all Waybar clock modules (`clock` in base, `clock#date` in themes) to launch it via `nomarchy-launch-or-focus-tui`. Provides a functional calendar across the entire distro.
 - _2026-05-31_ — **Waybar theme fixes (summer-day/night).** Retargeted broken `on-click` actions in the `summer-day` and `summer-night` themes to Nomarchy scripts. Fixed `custom/launcher` (was `wofi/kitty`), `network` (was `wifimenu.sh`), and `custom/powermenu` (was `wlogout`) to use `nomarchy-menu`, `nomarchy-launch-wifi`, and `nomarchy-menu power` respectively. Removed hardcoded `nvidia_0` backlight device from `summer-day` to allow Waybar auto-detection.
 - _2026-05-31_ — **Pillar 9: Live VM runtime QA — complete.** Successfully drove the entire distro through a comprehensive runtime audit in a live VM. Verified the installer loop, first-boot UX, core system/home modules, desktop stack (Hyprland, waybar, walker, mako, swayosd), curated apps, theme engine (all 21 palettes), every `nomarchy-*` script, and form-factor presets. Fixed multiple runtime-only bugs (D-Bus errors, path mismatches, broken keybindings, renamed packages) that were invisible to static evaluation. This pillar closes the "runtime verification" requirement for the entire project.
