# Roadmap & changelog

Forward-looking plans, plus a running log of shipped fixes (the
"Known issues & follow-ups" section). Split out of the README so that
stays a focused entry point — what Nomarchy is, how to install it, and
how to override it. Items marked ✓ are shipped.

## Roadmap
- **Menu system** (apps launcher + theme switching + system actions), built
  on rofi 2.0 (native Wayland on 26.05) — its `.rasi` theme is baked from
  theme-state.json like every other app, with rich per-element styling:
  - ✓ shipped: `modules/home/rofi.nix` (per-element theme generated from
    the palette, `themes/<slug>/rofi.rasi` whole-swap) and the
    `nomarchy-menu` dispatcher: root picker (no args) · `power`
    (lock/logout/suspend/hibernate/reboot/shutdown, SUPER+X) ·
    `theme` (SUPER+T) · `clipboard` (cliphist, SUPER+CTRL+V) · `calc`
    (rofi-calc, live, SUPER+CTRL+C) · `files` (fd → xdg-open,
    SUPER+CTRL+F) · `emoji` (rofi-emoji, SUPER+CTRL+E) · `web` (Google).
    SUPER+D is `rofi -show drun`.
  - ✓ shipped modules: `network` (nmtui in `$TERMINAL`) · `bluetooth`
    (blueman-manager) · `capture` (grim/slurp submenu: region/full →
    clipboard/file, saved to `~/Pictures/Screenshots`) · `keybinds` (the
    cheatsheet, see below) · `ask` (free-text → claude CLI in a terminal;
    auths via OAuth, no API key; pulled fresh via `npx
    @anthropic-ai/claude-code@latest` rather than the nixpkgs package, which
    lags model releases — `nodejs` is bundled for npx; REPL stays open)
  - ✓ keybindings cheatsheet: `modules/home/keybinds.nix` is the **single
    source** for both the Hyprland binds and the SUPER+? rofi list, so they
    can't drift; `nomarchy-menu keybinds` renders the padded two-column
    sheet (generated/mouse binds carried in its `extra` rows)
  - ✓ shipped binds: `SUPER+Space` → `rofi -show drun` (quick launch) ·
    `SUPER+M` → `nomarchy-menu` (main menu) · `SUPER+?` → the cheatsheet;
    `SUPER+D` stays `-show drun`
  - launcher icons: ✓ `show-icons` on, drawing from the theme's icon set
    (Papirus, via the icon-themes work below)
  - decision record: resolves the old Walker/Lua question — no GTK4
    launcher, no second theming pipeline; the dispatcher owns the menu
    structure, so the renderer stays swappable (we moved fuzzel → rofi 2.0
    once mainline gained native Wayland, for its richer theming)
  - ✓ **Organize the picker into category submenus:** the root picker had grown
    into a long flat list of 16 entries. It's now six: **Apps · Theme · Tools ›
    · System › · Power · Keybindings**. `Tools` (Calculator, Clipboard, Emoji,
    Files, Web, Capture, Ask) and `System` (Network, Bluetooth, DND, and the
    self-gated Snapshots / Power-profile) are submenus the dispatcher routes via
    `nomarchy-menu tools|system`, each ending in a `← Back` entry that re-opens
    the root. The direct `SUPER+CTRL+<mnemonic>` binds still hit the leaves
    straight (bypassing the menu), and the self-gated entries still hide when
    unavailable. Remaining (optional): a **Look & Feel** category once there are
    more appearance toggles to group with Theme (night-light, wallpaper).
    **General pattern (ongoing):** the grouping is a standing convention, not a
    one-off — any new feature that earns a menu entry must be placed in the
    right submenu (don't let the root creep back to a flat list), with its
    direct `SUPER+CTRL+<mnemonic>` bind and self-gating as applicable.
  - ✓ **Back everywhere:** every list menu now ends with a `↩ Back` entry that
    returns one level up (power/theme/power-profile/clipboard/files/capture,
    not just Tools/System), so you never have to Esc out and reopen. A `back`
    helper + a shared `BACK` label keep it uniform; matched exactly so it can't
    collide with clipboard/filename content. Esc still quits instantly.
- ✓ **Menu modules from rofi plugins:** the old `calc` flow committed the
  expression blind (result only in the *next* menu's `-mesg`) and `qalc -t`
  misparsed common phrasings (`15% of 200` → `rem(15, 1 B)`, the natural-
  language "of" tripping the CLI). Resolved by adopting purpose-built rofi
  modi (`programs.rofi.plugins`), all themed through the same `.rasi`:
  - **calc** → **rofi-calc**: live results as you type via libqalculate
    directly (dodging the qalc-CLI "of" bug), Enter copies, menu persists
    to chain calculations.
  - **emoji** → **rofi-emoji** (new module, SUPER+CTRL+E): glyph picker,
    copies via the plugin's Wayland clipboard adapter.
  - **files** stays the hand-rolled `fd` → `rofi -dmenu` → xdg-open fuzzy
    search: rofi-file-browser-extended was tried and dropped — its
    navigate-a-tree model felt worse than flat fuzzy-find for a quick
    launcher, and yazi (SUPER+E) already covers real browsing.
- **More menu modules from rofi tools:** the script-based counterparts
  (run via `rofi -dmenu`, like the hand-rolled modules), each a deliberate
  replacement of an existing flow: **rofi-network-manager** (a keyboard
  wifi/VPN picker vs today's `nmtui`-in-terminal `network`), **rofi-rbw /
  rofi-pass** (a secrets module — Bitwarden via rbw, or `pass` — pairs with
  `keys.nix`), and **rofi-pulse-select** (an audio sink/source switcher).
  Decide per-module whether it earns replacing the current path.
- **Theme parity with legacy:** summer-day/night now carry their legacy
  bar layouts as `waybar.jsonc` whole-swaps (adapted: dead legacy script
  modules dropped, Nerd-Fonts-v2 codepoints remapped to FontAwesome/v3,
  logo button opens nomarchy-menu); the other four identity themes are
  palette recolors and already match. Remaining: a visual pass over all
  six on the live ISO
- **Per-theme rofi identity:** the `themes/<slug>/rofi.rasi` whole-swap
  ships, and summer-day/night carry their legacy designs (inverted window,
  green inputbar, yellow bottom-border). Remaining: author `.rasi`
  identities for the other four ported themes if/when they want one (the
  generated palette theme is the default and looks fine)
- ✓ **Visual theme picker (preview thumbnails):** `nomarchy-menu theme` is now
  a rofi **icon grid of real desktop previews** instead of a plain-text list —
  each theme a screenshot of its themed desktop (waybar + floating terminal),
  pretty name beneath, **grouped dark-first then light** in one scrollable grid
  (the previews make the mode obvious, so no light/dark submenu split), the
  active theme marked `✓`, ending in `↩ Back`. The grid, the Name→slug map and
  the active mark are all **generated at eval time** from the preset JSONs in
  `rofi.nix` (`builtins.readDir` + `fromJSON`); "active" is just `t.slug`, since
  every switch rebuilds the menu. Grid layout via a per-invocation `-theme-str`
  (`listview { columns: 3; flow: horizontal; }` so Down scrolls row-by-row, +
  vertical `element` cards, name centred below). **Sizing gotcha (learned the
  hard way):** rofi's `element-icon` `size` is a **single value → a square
  cell** (a two-value `WxH` is silently collapsed), and the icon is *contained*
  in that square. So a 16:9 preview letterboxes (theme-coloured bands top/
  bottom), and a cell can't be shorter-than-square without the bands returning.
  The fix: a build-time imagemagick step **centre-crops each preview to a
  square** so it fills the cell edge-to-edge; the window width is derived so a
  column is exactly the icon side (no slack margins). One knob, `themeGridIconW`
  (240px), drives both icon and window. **Workflow:** Bernardo captures previews
  on real hardware and commits them as `themes/<slug>/preview.png`, **already
  downscaled to 480×270** (~2.4 MB total for all 21, vs ~28 MB full-res) — the
  source stays 16:9 and untouched; only the *displayed* thumb is squared at
  build, so the crop is reversible. Graceful fallback when a theme has no
  `preview.png`: a plain-name row, so it degrades cleanly.
  (A headless VM-render route — `runNixOSTest` + software-GL Hyprland
  (`LIBGL_ALWAYS_SOFTWARE` on virtio-gpu) + `machine.screenshot()` QMP
  framebuffer dump — was prototyped 2026-06-19 and **works** (themed waybar
  rendered + captured); real-hardware capture was chosen for fidelity +
  simplicity, with the VM route as a documented fallback if hand-capturing all
  themes gets tedious.)
- **Faster switches:** move `backgrounds/` out of the flake source. Diagnosis
  (confirmed): `themes/` is 86 MB and `backgrounds/` is **all** of it — the
  palette JSONs + per-theme overrides are only ~208 KB, and the wallpapers are
  **never read at Nix eval** (only the Python `swww` path uses them). But
  `theme-state.json` is git-tracked, so every `apply` rewrites it → the flake
  tree changes → Nix re-copies the whole 86 MB source before `home-manager
  switch` can evaluate. You pay an 86 MB copy to change a 1 KB file.
  **Decided approach (deferred — don't want the extra moving part yet):**
  Option 1, a **separate pinned wallpapers artifact** — a `Nomarchy-wallpapers`
  repo or release tarball, pulled once via a flake input / `fetchurl` (pinned
  by hash → content-addressed, never re-copied on a state write), with
  `nomarchy-theme-sync` reading wallpapers from that stable store path (the
  `NOMARCHY_DEFAULT_THEMES` env hook already anticipates external theme
  assets). Keeps eval **pure**; the live ISO still bakes them in (fetched at
  build). A state write then re-copies only ~208 KB. Rejected alternative:
  moving `theme-state.json` out to `~/.config` + `--impure` eval (one repo, no
  second artifact, but trades away the in-tree-pinned-state reproducibility).
  Follow-on if `home-manager switch` itself is still the bottleneck after the
  copy is gone: **pre-built theme variants** (build each theme's generation
  ahead of time so a switch just activates a cached one).
- Greeter (tuigreet/SDDM) theming from the same JSON (Plymouth ships since
  v1: `nomarchy.system.plymouth.*`, background tinted from the state file)
- Installer round 2: multi-disk BTRFS RAID, impermanence, BIOS/legacy
  boot (v1 `nomarchy-install` is single-disk UEFI — see `pkgs/nomarchy-install`)
- launch-or-focus UX scripts (swayosd volume/brightness OSD ships since v1:
  `nomarchy.osd.*`, media keys drive `swayosd-client`, themed from the JSON)
- **Distro branding, round 2:** `distroName = "Nomarchy"` ships
  (os-release `PRETTY_NAME`, systemd-boot entries, ISO menu label).
  ✓ tuigreet greeting (`Welcome to <distroName>`) and a branded `users.motd`
  (doubling as a helper cheat sheet), both keyed off `distroName`.
  ✓ `isoImage.splashImage` — the vendored vector logo
  (`modules/nixos/branding/logo.svg`, from legacy) recolored to the palette
  accent on the theme base, built at ISO-build time (`hosts/live.nix`).
  Remaining: `isoImage.grubTheme` so UEFI boot matches the isolinux splash
  (needs a full grub theme dir), and the `distroId` question (it changes
  `DEFAULT_HOSTNAME` and upstream `isNixos` checks — needs a test pass;
  nixos-* CLI names stay regardless)
- ✓ **fastfetch branding:** `modules/home/fastfetch.nix`
  (`nomarchy.fastfetch.enable`) — the vendored vector logo, recolored to
  the palette accent and rendered to compact block-art via chafa at build
  time (tracks the theme), fronting a curated module list. Replaces the
  oversized legacy ASCII with a themed, sized logo.
- ✓ **Nomarchy logo font in Waybar:** vendored `Nomarchy.ttf`
  (`modules/nixos/branding/`), installed via `fonts.packages`, and the
  summer-day/night menu buttons now use its `U+F000` glyph with
  `font-family: Nomarchy` pinned in their CSS (Nerd Fonts also occupy
  U+F000, so the pin is required). The other themes have no logo button.
- ✓ **Quality-of-life command aliases:** a curated set ships on by default in
  `modules/home/shell.nix` — navigation (`..`/`...`/`....`), a git block
  (`g`, `gst`, `ga`/`gaa`, `gc`/`gcm`, `gco`/`gsw`, `gb`, `gd`/`gds`,
  `gl`/`glg`, `gp`/`gpl`, `gf`), and a nix block (`ns`, `nr`, `nfu`, `nfc`,
  `nsearch`, `ngc`), plus `path` and `reload`. Scope decision: short where it
  helps but **never shadow a real binary** (same rule as rg/fd — the git block
  deliberately avoids `gs`/ghostscript); system/home rebuilds keep their full
  `sys-update`/`home-update` names rather than getting cryptic aliases. The set
  is documented in README §5 (Day-to-day), and `alias` lists them in-shell.
- **Theme-switch feedback:** ✓ the "rebuilding…" notification is now
  persistent (timeout 0) and replaced in place by "applied ✓" / failure
  via a synchronous tag, so a multi-minute switch never reads as a failed
  selection. (An honest indeterminate indicator — HM gives no % — a
  literal progress widget would be cosmetic; revisit only if wanted.)
- **Icon themes:** ✓ ships `papirus-icon-theme`; the resolved name lives on
  `nomarchy.theme.iconTheme` (the JSON's optional `icons` field, else
  Papirus-Dark/Light by `mode`) and feeds both Stylix's `gtk.iconTheme`
  (Thunar/GTK apps) and rofi's `show-icons`. Remaining (optional): per-theme
  `icons` overrides for the presets, or shipping more icon packs.
- **Nicer shell out of the box:** ✓ zsh is the default login shell, with a
  starship prompt themed from the JSON, autosuggestions + syntax
  highlighting, and modern-CLI ergonomics — `cat`→bat (theme "ansi", so it
  tracks the palette), `ls`→eza, `cd`→zoxide, plus `lt`/`tree`.
  `nomarchy.shell.enable`. (Deliberately did NOT alias grep→rg / find→fd:
  their flags differ enough to surprise; `rg`/`fd` ship as themselves.)
- ✓ **Default application suite:** a starter complete-workstation set —
  `libreoffice-fresh`, `vscode`, `gimp`, `inkscape` — ships *active* in the
  downstream `templates/downstream/home.nix` `home.packages`, with the heavier
  opt-ins (`texliveFull` — multi-GB; `texliveMedium` is lighter — plus
  browser/email) commented just below. **Decision: no `nomarchy.apps.*` option
  surface.** Unlike `nomarchy.services.*` (real config behind each toggle —
  systemd units, subuid ranges, the Flathub oneshot), a bare package install
  has nothing behind the toggle: `mkIf x { environment.systemPackages = [p]; }`
  just reinholds what a package list already gives, and the honest opt-out for
  a package is *deleting the line*. So the suite is the user's own curated list
  (extending the existing `# firefox` convention), not a distro-module feature —
  which also keeps the apps out of the live ISO automatically (it never starts
  from the template) and respects that editor/office/graphics are personal-taste
  choices, not defaults to impose. Unfree `vscode` evaluates fine — `mkFlake`
  and the system both set `allowUnfree = true`.
- ✓ **Plymouth logo contrast:** the shipped art was a fixed navy that
  vanished on dark bases. `modules/nixos/plymouth.nix` now recolors every
  element from the palette at build time (flat fill, alpha kept):
  logo/lock/bullet → text, entry/progress-box → surface, progress-bar →
  accent. Reads on light and dark; follows the theme as of the last system
  rebuild (like the background tint).
- ✓ **Hibernate double-unlock:** on resume from hibernate the LUKS
  passphrase already gates the machine, but locking hyprlock before sleep
  meant a second password. Fixed by *not locking* before an encrypted
  hibernate: a `nomarchy-lock-before-sleep` systemd unit
  (`modules/nixos/default.nix`) takes over from hypridle's `before_sleep_cmd`
  and locks on the RAM-resume sleeps (suspend / hybrid-sleep / suspend-then-
  hibernate) always, but skips `hibernate.target` when the disk is LUKS-
  encrypted. (A first attempt that dismissed hyprlock *after* resume was
  wrong — killing a Wayland session-lock client trips its "go to a tty"
  crash failsafe instead of unlocking, which is the error screen it caused.)
- ✓ **Key agents & pinentry:** ships `modules/home/keys.nix`
  (`nomarchy.keys.enable`): one agent — `services.gpg-agent` with
  `enableSshSupport` fronts SSH, so a single `pinentry-qt` (native-Wayland,
  Stylix-themed Qt) handles GPG and SSH passphrases alike. `SSH_AUTH_SOCK`
  comes from the agent's zsh integration; cache TTLs (30 min / 2 h) govern
  re-prompting. gnome-keyring stays the Secret Service (modern versions run
  no SSH agent, so no socket contention); screen lock doesn't flush the
  cache. Remaining (optional): a session-level `SSH_AUTH_SOCK` export so GUI
  clients launched outside a shell also see the agent.
- **Sanitize & organize the repo:** a housekeeping pass for consistency
  and clarity.
  - ✓ pruned now-redundant config: the installer no longer writes
    `console.useXkbConfig` / `boot.initrd.systemd.enable` into `system.nix`
    (distro-wide defaults since the LUKS-keymap fix), nor the offline-pin
    test fixture in `flake.nix`.
  - ✓ reconciled the README option tables with the live `nomarchy.*`
    surface (added keys/fastfetch/snapper/greeter.autoLogin).
  - ✓ untracked `.claude/settings.local.json` (machine-local) + gitignored.
  - ✓ **branch/release model:** `main` is the development default; `v1` is
    the release pointer downstreams pin (`?ref=v1`), advanced to main once
    a batch is tested — rolling, no tags. Brought `main` current (it was a
    stale legacy-merge), and deleted the dead `refactor` / `wave/nixos-26.05`
    branches (kept `legacy` for history). See the comment in `flake.nix`.
  - ✓ re-checked that every file earns its place under the
    `modules`/`hosts`/`themes`/`pkgs`/`tools` rule of thumb: no orphaned
    modules (`keybinds.nix` is a *data* module `import`-ed by hyprland/rofi,
    so correctly absent from `default.nix`), no dead-code markers, no
    editor/backup cruft, each `themes/<slug>.json` palette pairs with its
    optional `<slug>/` overrides dir, and `hosts/{default,live}` are the
    documented reference + ISO hosts. Structure is clean as-is.
  - Open decision (deferred): the repo declares **no formatter** (no flake
    `formatter`, no `.editorconfig`); `.nix` files use deliberate aligned
    hand-formatting, so `nixfmt-rfc-style --check` flags ~33 files. Adopting a
    formatter would be a one-time repo-wide reformat that flattens that
    alignment — a maintainer call, not a silent cleanup, so left untouched.
- **Full docs review & restructure:** a dedicated pass over all the prose,
  not just the code-adjacent cleanup the repo-sanitize item covers. The
  README has grown to ~540 lines with a ~200-line roadmap inline — the
  biggest single move is likely **splitting the roadmap out** (e.g.
  `ROADMAP.md` / `docs/`) so the README stays a focused "what it is / how
  to install / how to override" entry point. Also: reconcile every option
  table against the live `nomarchy.*` surface (snapper and others are
  missing); a pass over `docs/OVERRIDES.md` + `docs/TESTING.md` and the
  `templates/downstream/README.md` for drift; check the install/first-run
  story reads cleanly end to end; and decide whether anything wants a real
  docs site vs. staying Markdown-in-repo. Pairs with the first-boot welcome
  and control-center items (shared "how do I…" surface).
- **Laptop power / battery management:** a real power story behind a
  `nomarchy.system.power.*` surface (`modules/nixos/power.nix`), replacing the
  old "only `services.upower` for Waybar reporting" baseline:
  - ✓ **profiles:** `power-profiles-daemon` ships by default (the upstream-
    aligned choice — power-saver/balanced/performance via `powerprofilesctl`,
    switched through polkit so no root prompt). A `power-profile` menu module
    (in the SUPER+M picker) and the first Waybar `custom/*` indicator (click to
    cycle) both **self-gate** on a battery being present + PPD running, so they
    hide on desktops and under TLP — no system→home wiring. **TLP** is the
    opt-in (`backend = "tlp"`) for deeper battery tuning; the two are mutually
    exclusive (asserted).
  - ✓ **thermal:** `thermald` behind `power.thermal.enable`; the installer
    turns it on for a `GenuineIntel` CPU.
  - ✓ **longevity:** `power.batteryChargeLimit` (e.g. 80) — a backend-
    independent sysfs oneshot writes `charge_control_end_threshold`. Off by
    default; the installer scaffolds it commented-out on laptops.
  - ✓ **installer:** writes `power.laptop = true` (battery probe) and
    `power.thermal.enable` (Intel) into the generated `system.nix`.
  - ✓ **idle cohesion:** `modules/home/idle.nix` now suspends only on
    battery (and sooner — 15 min vs the old fixed 30), gating the hypridle
    suspend listener on a `nomarchy-on-ac` probe so a plugged-in machine
    stays up mid-idle; lock/screen-off are unchanged on both sources.
    logind's lid handling is left at its defaults (suspend on lid close,
    ignore when docked) — an explicit "I'm done" that coheres with the
    idle behaviour.
  - Remaining: a boot-only→event-driven charge-limit re-apply (udev) if a
    firmware resets the threshold on unplug.
  - ✓ **Waybar parity:** the `custom/powerprofile` indicator now shows in the
    summer-day/night whole-swap themes too. `powerProfileStatus`/`Cycle` are
    named `writeShellScriptBin`s on PATH (`waybar.nix` home.packages), so the
    generated config and the static `waybar.jsonc` both exec them by bare
    name (the same parity the DND bell has). General pattern: any new
    generated-config module needs adding to the whole-swap themes too.
- **Full hardware enablement (beyond nixos-hardware):** nixos-hardware
  profiles cover *basic* per-model functionality (quirks, drivers), but the
  *advanced* features of a machine — keyed more on the CPU/GPU generation
  than the model — are left for the user to wire up by hand. Close that gap
  without making it finnicky: extend the installer's existing autodetection
  (DMI → nixos-hardware profile today; add CPU vendor/arch, GPU, NPU,
  fingerprint reader, SSD) to switch on the *safe, broadly-beneficial*
  features automatically, and expose a small `nomarchy.hardware.*` surface
  (per-vendor where it helps, e.g. `nomarchy.hardware.amd.*`) for the heavy
  or experimental bits. Goal: full utilisation out of the box — opt-*out* for
  the safe defaults, opt-*in* for the multi-GB / experimental extras.
  Complements nixos-hardware (model quirks) rather than replacing it; keep
  the detection in the installer's `hardware-db` so an installed machine
  bakes the right defaults, all overridable through `nomarchy.hardware.*`.
  - ✓ **Mechanism + broad seed shipped** (`modules/nixos/hardware.nix`): a
    vendor-keyed `nomarchy.hardware.*` surface (`intel`, `amd`, `fingerprint`,
    `npu`), `hardware-db.sh` extended to detect Intel/AMD, a fingerprint reader
    (libfprint USB vendor IDs) and an NPU (Intel VPU / AMD XDNA PCI IDs), and
    the installer bakes the matching toggles into `system.nix` — safe defaults
    active (GuC/HuC, amd-pstate, AMD VA-API env, fprintd), heavy/experimental
    opt-ins commented (Intel compute-runtime, ROCm, fingerprint PAM, NPU
    driver). Audited against the nixos-hardware commons so it only fills the
    gap above them — microcode / the media-driver VA-API stack / weekly fstrim
    already come from `common-cpu-*` / `common-gpu-*` / `common-pc-ssd`.
    Exercised live on the dev machine's detection (an AMD Ryzen-AI laptop: AMD
    + fingerprint + NPU all detected) and a toggles-on build (`amd_pstate=active`
    + `i915.enable_guc=3` in kernel-params, `fprintd.service` present).
    **Remaining: on-hardware verification of the runtime bits (AMD/NPU/Intel
    GPU-compute) — none are testable in CI or on the Intel Latitudes for the
    AMD paths.** SSD TRIM is intentionally left to `common-pc-ssd`.
  - ✓ **Hardening (driver-gen + kernel awareness):** `intel.guc` emits the
    *i915* param, so the installer turns it off when the GPU is on the newer
    `xe` driver (Lunar Lake / Battlemage / Panther Lake — GuC is default-on
    there); the NPU detector matches the PCI *accelerator class* (not just a
    device-ID list) so new gens are caught without a code change; and a
    `nomarchy.hardware.latestKernel` escape hatch (+ a build-time warning when
    `npu.enable` predates the shipped kernel) covers very-new hardware whose
    drivers only just landed. A config-assertion VM test guards the wiring
    (`checks.hardware-toggles`: kernel cmdline + fprintd + PAM, booted in a VM).
  Worked example — ThinkPad T14s (Ryzen 7 PRO 7840U + Radeon 780M):
  - **GPU compute — ROCm:** the 780M is an RDNA3 iGPU (gfx1103) ROCm doesn't
    officially list, so it needs `HSA_OVERRIDE_GFX_VERSION=11.0.0`. Multi-GB
    closure → opt-in (`nomarchy.hardware.amd.rocm.enable`); unlocks GPU
    PyTorch / Ollama.
  - **Ryzen AI NPU (XDNA):** the `amdxdna` kernel driver (mainline 6.14+) +
    the XRT/xdna userspace runtime + firmware. Niche/experimental → opt-in.
  - **AMD P-State EPP (Zen 4 power):** `amd_pstate=active` for the EPP
    governor, which power-profiles-daemon (already shipped, `power.nix`)
    drives per profile. Broadly beneficial on Zen 2+ → default on when the
    installer sees an AMD CPU.
  - **Hardware video acceleration (VA-API):** mesa's radeonsi exposes VA-API
    on AMD (`LIBVA_DRIVER_NAME=radeonsi`, libva + drivers in
    `hardware.graphics.extraPackages`); Intel uses `intel-media-driver`.
    Broadly beneficial → default on, vendor-detected.
  - **LVFS firmware & biometrics:** fwupd already ships (✓, `services.fwupd`).
    Add fingerprint: `services.fprintd` when a reader is detected, with
    opt-in PAM integration for login/sudo (password-only stays the default
    for the cautious).
  - **SSD periodic TRIM:** `services.fstrim.enable` (weekly) — safe and
    beneficial, so default on (trivial enough it may warrant being
    distro-wide regardless).
  Sub-items here can graduate into their own roadmap entries as they're
  scoped; the unifying work is the detection + `nomarchy.hardware.*` surface.
- **Opt-in services & integrations:** the counterpart to the opt-*out*
  application suite above — heavier or more personal integrations shipped
  **off by default**, each a `nomarchy.services.<name>.enable` toggle a
  downstream flips on in one line. Keeps the base lean while making common
  additions trivial. **✓ Seventeen shipped** in `modules/nixos/services.nix`
  (system-side), each with a commented example in the downstream `system.nix`
  template: `tailscale`, `syncthing` (runs as the login user, GUI on
  127.0.0.1:8384), `podman` (rootless, `docker` aliased, user subuid/subgid),
  `flatpak` (+ Flathub remote added by a oneshot), `pika` (Pika Backup GUI),
  `steam` (`programs.steam` — the 32-bit stack, controller udev, Remote-Play
  ports a bare package can't), `libvirt` (libvirtd + virt-manager, user added
  to the `libvirtd` group), `obs` (OBS Studio + a v4l2loopback virtual camera
  usable as a webcam in Zoom/Teams), `docker` (rootful; asserts against the
  podman docker-compat), `kdeconnect`, `gamemode`, `adb` (android-tools;
  systemd handles the udev rules), `wireshark` (Qt GUI + the `wireshark`
  group), `ollama` (local LLM API on 127.0.0.1:11434), `printing` (CUPS +
  Avahi mDNS), `openrgb` (RGB lighting daemon), and `restic` (scheduled
  daily backup — a small option surface: `repository`/`passwordFile`/`paths`,
  7/4/6 retention). More candidates by area:
  - ✓ **cloud/sync:** Syncthing (`services.syncthing`); Nextcloud client is a
    bare tray app (in the app-suite menu, not a service)
  - ✓ **local AI:** Ollama (`nomarchy.services.ollama`, optional GPU accel)
    ships; LM Studio is a (commented) app-suite package (a bare GUI, no
    service) — pairs with the menu's Ask-Claude philosophy
  - ✓ **containers/VMs:** Podman (`virtualisation.podman`); libvirt +
    virt-manager (`nomarchy.services.libvirt`); Docker (`nomarchy.services.docker`)
  - ✓ **networking:** Tailscale (`services.tailscale`); WireGuard needs no
    toggle — NetworkManager (on by default) imports `.conf` tunnels natively;
    the `wireguard-tools` CLI is in the app-suite menu
  - ✓ **gaming/media:** Steam (`nomarchy.services.steam`); OBS Studio
    (`nomarchy.services.obs`, with the v4l2loopback virtual camera); GameMode
    (`nomarchy.services.gamemode`)
  - ✓ **devices:** printing (CUPS + Avahi, `nomarchy.services.printing`); KDE
    Connect (`nomarchy.services.kdeconnect`); OpenRGB
    (`nomarchy.services.openrgb`). Plus dev tooling — Android `adb` and
    `wireshark` toggles
  - ✓ **backup:** Pika Backup (`pika-backup`, GUI over Borg); scheduled
    headless restic (`nomarchy.services.restic`)
  - ✓ **escape hatch:** Flatpak (`services.flatpak`) + Flathub, for apps
    outside nixpkgs

  Surface decided: `nomarchy.services.*`, system-side for system services
  (home-side ones can extend the same prefix later). Remaining: curate the
  rest (Ollama, containers, Steam/OBS, printing, backups, Flatpak …). The
  opt-out application *suite* is deliberately **not** a parallel
  `nomarchy.apps.*` surface — it's a curated `home.packages` list in the
  downstream template (see "Default application suite" above), since a bare
  package install has no config to put behind a toggle. Unfree entries are
  already covered (`allowUnfree = true`).
- ✓ **Display / monitor management:** declarative `nomarchy.monitors` (a
  per-output schema — name/resolution/position/scale/transform/mirror/
  bitdepth/vrr/disable) generates Hyprland `monitor` rules, keeping the
  `,preferred,auto,1` wildcard as the fallback; Hyprland applies them on
  hotplug, so a declared external/dock output arranges itself on connect
  (no kanshi — it fights Hyprland's own output management). `nwg-displays`
  ships behind `nomarchy.displays.enable` as an interactive arranger (a
  helper to find values; the declarative config stays the source of truth —
  its output file isn't sourced). Remaining: true docked/undocked **profile
  switching** of the *same* outputs (Hyprland's per-output rules cover the
  common "external connects → arrange" case, not multi-layout toggles), and
  optionally workspace-to-monitor binding.
- ✓ **Night light / blue-light filter:** `nomarchy.nightlight` (opt-in) —
  a scheduled colour-temperature shift via `hyprsunset` (Hyprland-native),
  warm at night, identity (no shift) by day. `modules/home/nightlight.nix`
  drives the HM `services.hyprsunset` with two time-based profiles
  (`sunrise` → identity, `sunset` → `temperature`), so hyprsunset handles the
  schedule and the on-login state. Active-profile-at-session-start was
  confirmed on hardware (2026-06-18). ✓ **Menu + Waybar toggle:**
  `nomarchy-nightlight` (in `nightlight.nix`, on PATH) starts/stops the
  hyprsunset *service* — `systemctl --user is-active` is the single source of
  truth, the screen restores to true colours when stopped, and it forces the
  filter off for colour-sensitive work and back on without touching config. A
  `nomarchy-menu nightlight` entry (System submenu, self-gated on the unit
  existing) and a self-gating Waybar `custom/nightlight` indicator (moon = on,
  sun = off; in the generated bar and both summer whole-swaps) drive it.
  The toggle is **session-scoped by design**: `stop` halts the running unit
  but it's `WantedBy=graphical-session.target`, so the next login auto-starts
  it and night-light returns to its schedule (off never persists). Remaining
  (optional): (1) **persistent off** — a state marker
  (`~/.local/state/nomarchy/nightlight-off`) the unit honours via
  `ConditionPathExists=!%h/…`, so a manual off survives logout/reboot until
  toggled back; (2) geo (lat/long) auto sunset/sunrise (would mean wlsunset,
  which schedules by location). Pending an on-machine check that stopping
  hyprsunset cleanly restores the gamma.
- **Keyboard layouts (per-device + switching):**
  - ✓ **Per-device declarative layout:** `nomarchy.keyboard.devices`
    (`{ "<hyprctl-device-name>" = { layout; variant; }; }`) generates Hyprland
    `device` blocks that override the session `nomarchy.keyboard.layout` for a
    named keyboard — e.g. an external board that's physically a different
    layout than the laptop's. Hyprland applies it whenever that device
    connects (the "external keyboard remembers its layout" case, done the
    declarative way). A Waybar `hyprland/language` indicator shows the active
    layout, gated on more than one layout being in play (comma in the session
    layout, or any per-device override) so single-layout bars stay clean.
  - ✓ **Interactive new-keyboard prompt (runtime + persist):** set
    `nomarchy.keyboard.layouts` (candidate layouts) and a `nomarchy-keyboard-
    watch` daemon runs (exec-once): it polls `hyprctl devices`, and when a
    keyboard connects *after* login that isn't in `keyboard.devices` and
    hasn't been chosen before, it pops a rofi layout picker, applies the
    choice as a **per-device** `hyprctl keyword device[<name>]:kb_layout` (the
    runtime twin of the declarative `device{}` blocks — so it isolates that
    one keyboard and never touches the built-in board), and remembers it
    per-device in `~/.local/state/nomarchy/keyboard-layouts` — re-applied
    silently on later reconnects. The boot-time set (incl. the built-in
    keyboard) is never prompted. The runtime-remember complement to the
    declarative `keyboard.devices`; a stateful runtime piece by design.
    **Picker verified on hardware (2026-06-18)**; the first cut applied the
    choice with `switchxkblayout` (a global layout-index flip) and merged the
    candidate pool into `input.kb_layout`, so a selection leaked onto the
    laptop keyboard and stuck after unplug — fixed by the per-device keyword +
    keeping the pool out of the session layout. Remaining (bonus): offer to
    write a choice into `keyboard.devices` so it graduates to the reproducible
    config; **re-verify the per-device isolation on hardware**.
  - Remaining: a multi-layout cycle bind (`hyprctl switchxkblayout` / xkb
    `grp:` options) for switching layouts on one keyboard; add the
    `hyprland/language` module to the summer whole-swap themes for parity
    (the gating doesn't translate to their static JSON). Keep the system
    (console/initrd) and session layouts in sync (the LUKS-keymap work).
- ✓ **Do-Not-Disturb:** swaync DND toggle wired into the menu
  (`nomarchy-menu dnd`, in the picker, SUPER+CTRL+D) and a Waybar bell
  indicator (`custom/notification` via `swaync-client -swb`: shows the
  notification count + DND state, left-click toggles the panel,
  right-click toggles DND). Turning DND off confirms with a toast; turning
  it on is silent (notifications are suppressed — the bell-off glyph is the
  cue).
- ✓ **Snapshot browse/restore UX:** `nomarchy-menu snapshot` (in the SUPER+M
  picker, self-gated on snapper) launches **btrfs-assistant** — the
  desktop browse/diff/restore/rollback UI, elevating via polkit (the safe
  choice for a destructive, root-only op vs a fat-fingerable rofi rollback).
  Shipped system-side gated on `nomarchy.system.snapper`. Also extended
  snapper to snapshot **/home** by default (hourly 5 / daily 7 / weekly 4)
  when it's its own BTRFS subvolume; a boot oneshot creates the required
  `/home/.snapshots` subvolume if missing (covers existing installs, no disko
  change). **The backend is VM-verified** (a full BTRFS+LUKS install: both
  `root`+`home` configs, a `/home` timeline snapshot taken, `/home/.snapshots`
  a real subvolume, the oneshot `Result=success`).
  - ⚠ **Known bug — btrfs-assistant 2.2 segfaults on launch** in nixpkgs
    26.05: it crashes inside `libbtrfsutil.so.1.4.0` (a library ABI mismatch,
    confirmed in the VM regardless of GL/Qt platform — so it's not a VM/GL
    artifact and will crash on hardware too). The menu wiring is correct and
    the app is installed, but the GUI doesn't open. The snapshot *backend*
    (the actual snapshots) is unaffected. Fix path: a nixpkgs override aligning
    its libbtrfsutil, or wait for an upstream bump. ✓ **Fallback shipped:**
    the menu now launches `nomarchy-snapshots` (system-side, gated on
    `nomarchy.system.snapper`) instead — a keyboard-driven snapper
    browser/restore with no btrfs-assistant dependency. snapper is root-only
    here (no `ALLOW_USERS`) and rofi can't run as root under Wayland, so it
    runs in a terminal via `sudo` (one password prompt) and uses `fzf` to pick:
    browse/diff (read-only), restore files (`undochange`), or roll back (root
    config only) — each behind a typed-`yes` confirmation, which is *safer*
    than the fat-fingerable one-click rofi rollback this entry originally
    avoided. btrfs-assistant stays installed for when nixpkgs fixes it.
    **Pending an on-machine check of the restore/rollback paths.**
  - Remaining (optional): boot-from-snapshot needs a systemd-boot equivalent
    of grub-btrfs.
- ✓ **Update awareness:** `nomarchy.updates.enable` (opt-in, `modules/home/
  updates.nix`) — a `nomarchy-updates` checker on a systemd user timer
  (`.interval`, default daily) compares each **direct** branch-tracking flake
  input (nixpkgs, the Nomarchy input, home-manager, stylix … via `git
  ls-remote` vs the locked rev; offline → skipped, no false alarm) and, when
  the `flatpak` CLI is present (`.flatpak`), counts Flatpak updates. A
  self-gating Waybar `custom/updates` indicator (hidden until something's
  available; accent `󰚰 N`, signal-refreshed) + a notification that fires only
  when the count *grows* (so a daily timer never nags). Click → the upgrade
  flow in a terminal (`sys-update` / `flatpak update`, each confirmed). Purely
  passive — it never changes anything, augmenting the explicit rebuild flow.
  Indicator is in the generated bar and both summer whole-swaps. **Pending an
  on-machine check** (the ls-remote/notify/timer path needs a live session).
- **"nomarchy" control center:** a single TUI/GUI front-end over the common
  toggles — theme, power profile, opt-in services, display, DND — built on
  the same `nomarchy-theme-sync` / `nomarchy.*` surface the menu already
  uses. Plus a first-boot welcome that lands new installs in a guided "pick
  your theme / essentials" flow (ties into the branding work).

## Known issues & follow-ups
- ✓ **Yazi TOML parse error on startup:** yazi 26.x made fetchers'
  `group` field required, so `[[plugin.prepend_fetchers]]` failed to parse
  and yazi fell back to presets. Fixed by adding `group = "git"` to both
  git fetcher entries in `modules/home/yazi.nix` (the git plugin's
  `setup()` only renders the linemode; the fetcher still needs registering).
- ✓ **Starship prompt styling:** dropped the powerline look (the `[]`
  separator glyph + `bg:` fills) for a flat prompt — bold-accent directory,
  warn git branch, subtext status/duration, `❯` character, all plain
  colored text (`modules/home/shell.nix`). Also wired in `cmd_duration`,
  which was configured but never referenced in `format`.
- ✓ **xfce deprecation warnings:** moved `xfce.exo` → `pkgs.xfce4-exo` and
  the three Thunar plugins to their new top-level names in
  `modules/nixos/file-manager.nix`; the eval warnings are gone.
- ✓ **Rofi function keybindings:** direct `SUPER+CTRL+<mnemonic>` binds jump
  straight to each `nomarchy-menu` module — V clipboard · C calc · W web ·
  F files · N network · B bluetooth · S capture · A ask — added to
  `modules/home/keybinds.nix`, so they also show in the SUPER+? cheatsheet.
- ✓ **Enable nix-ld by default:** `programs.nix-ld.enable` is on distro-wide
  (`modules/nixos/default.nix`), so prebuilt/foreign dynamically-linked
  binaries run out of the box.
- ✓ **Hyprland border colors off for some themes:** the cause was v1
  forcing an `accent→accentAlt` gradient on every theme; legacy used a
  *solid* border (accent for nord/retro-82/lumon, the text tone for
  kanagawa/summer-day/summer-night). Added a palette-resolved `border`
  field (`{active, inactive}`) to the theme schema (`theme.nix`), consumed
  solid in `hyprland.nix`, and declared it in every preset so a switch
  always replaces it. All six identity themes now match legacy exactly.
- ✓ **Waybar shows non-existent workspaces:** the v1 summer port "fixed"
  legacy's deprecated `persistent_workspaces` (underscore — silently
  ignored by current Waybar, so legacy only ever showed existing
  workspaces) into the modern `persistent-workspaces` (hyphen), which
  Waybar honours → all 10 rendered as phantoms. Dropped the block from
  `themes/summer-{day,night}/waybar.jsonc`; the other themes use the
  generated `waybar.nix`, which never had it, so they already match.
- ✓ **GTK/Qt ignore the theme's light/dark mode:** Stylix set `polarity`
  but not the `org.freedesktop.appearance color-scheme` that GTK4/libadwaita
  and Qt6 read via the portal, so a light theme could still render apps
  dark. `stylix.nix` now sets `dconf` `org/gnome/desktop/interface
  color-scheme` = `prefer-light`/`prefer-dark` from `t.mode`
  (xdg-desktop-portal-gtk already ships, and `programs.dconf` is on
  system-side), so libadwaita/Qt follow the palette. Confirmed in a live
  session (headless QEMU): the portal's `org.freedesktop.appearance`
  `color-scheme` reads `1` on a dark theme and flips to `2` after switching
  to a light one (catppuccin-latte) — so xdg-desktop-portal-gtk does relay
  the dconf value GTK4/Qt apps read.
