+
+The `shell-defaults.json` bundled with the shell describes the
+fresh-install state. When the user has no `shell.json`, the shell uses
+the defaults verbatim. Once the user customizes anything, `shell.json`
+becomes the authoritative file — we do **not** deep-merge defaults back
+in. Pressing **Reset to defaults** in `omarchy launch bar-settings`
+rewrites `shell.json` from the current `shell-defaults.json`.

+  "bar": {

+    "centerAnchor": "calendar",

+
+### Storage rules
+
+1. **Every plugin instance is one entry.** Either in `bar.layout.<section>`
+   for bar widgets, or in `plugins[]` for panels, overlays, services,
+   menus, and anything else non-bar.
+2. **Settings are inline on the entry.** No `config:` sub-object, no
+   separate per-plugin settings file, no merge layers. The fields on each
+   entry are the values the plugin sees.
+3. **Enabled ⇔ present.** A plugin is enabled iff its id appears somewhere
+   in shell.json. To disable, remove it. (The bar settings UI does both.)
+4. **Multiple instances** are allowed when a manifest sets
+   `allowMultiple: true`. Each instance is independent — e.g. two clocks
+   in different timezones are just two `{"id":"calendar", "timezone": ...}`
+   entries with their own values.
+5. **`version: 1` is required** at the top level. The shell will fall back
+   to defaults rather than load an unknown version.

+# Noctalia plugin compatibility (omarchy-shell)
+
+The omarchy-shell can load most bar widget plugins from the
+[noctalia-dev/noctalia-plugins](https://github.com/noctalia-dev/noctalia-plugins)
+ecosystem without any modification to the plugin code.
+
+## Install a Noctalia plugin
+
+```sh
+git clone https://github.com/noctalia-dev/noctalia-plugins /tmp/noctalia-plugins
+ln -s /tmp/noctalia-plugins/asus-um5606-fan-state \
+      ~/.config/omarchy/plugins/asus-um5606-fan-state
+omarchy-shell-ipc shell rescanPlugins
+```
+
+The plugin id you see inside Omarchy is prefixed: `noctalia.asus-um5606-fan-state`.
+Add it via the bar customizer or by editing `~/.config/omarchy/shell.json` directly.
+
+## What's supported in v1
+
+| Noctalia concept | Omarchy support |
+|---|---|
+| `entryPoints.barWidget` | yes — registered through `BarWidgetRegistry` |
+| `entryPoints.panel` | yes — opened via `pluginApi.openPanel()` |
+| `entryPoints.settings` | yes — embedded in the bar-settings dialog |
+| `entryPoints.main` | yes — instantiated as a hidden service, exposed via `pluginApi.mainInstance` |
+| `entryPoints.desktopWidget` | **no** — skipped with a console warning |
+| `entryPoints.launcherProvider` | **no** — skipped with a console warning |
+| `entryPoints.controlCenterWidget` | **no** — skipped with a console warning |
+| Plugin i18n (`i18n/<lang>.json`) | **no** — `tr()` returns the raw key |
+| Plugin install from git URL | **no** — manual drop into `~/.config/omarchy/plugins/` |
+| Hot reload on plugin change | **no** — call `omarchy-shell-ipc shell rescanPlugins` |
+
+## Shim surface
+
+We ship just enough of Noctalia's QML namespace to render typical bar widgets.
+
+| Module | Symbols |
+|---|---|
+| `qs.Commons` | `Color`, `Style`, `Logger`, `Settings` (read-only), `I18n` (stub), `Time`, `Icons` (~50 entries), `ThemeIcons` (stub), `ShellState` (stub) |
+| `qs.Widgets` | `NText`, `NIcon`, `NIconButton`, `NBox`, `NButton`, `NPopupContextMenu`, `NScrollText`, `NToggle`, `NSpinBox`, `NSlider`, `NTextInput`, `NComboBox`, `NCheckbox`, `NDivider` |
+| `qs.Services.UI` | `BarService`, `TooltipService`, `PanelService` |
+| `qs.Services.System` | `HostService` (reads `/etc/os-release`) |
+| `qs.Services.Power` | `PowerProfileService` (returns `noctaliaPerformanceMode: false`) |
+
+Anything outside this surface logs a `console.warn` instead of crashing the
+shell, but the plugin may not render correctly.
+
+## `pluginApi` surface
+
+A Noctalia plugin's `pluginApi` is built per-plugin and injected onto the bar
+widget / panel / settings entry points. The implementation lives at
+`compat/noctalia/PluginApiFactory.qml`.
+
+| Property / method | Behaviour |
+|---|---|
+| `pluginId`, `pluginDir`, `manifest` | Provided as expected. |
+| `pluginSettings` | Live read of the plugin's entry in `~/.config/omarchy/shell.json`, merged with the manifest's `metadata.defaultSettings`. |
+| `mainInstance` | Live instance of `Main.qml` when the plugin declares one. |
+| `saveSettings()` | Persists the merged settings into the plugin's entry in `shell.json`. |
+| `openPanel(screen, btn)` / `closePanel(screen)` / `togglePanel(screen, btn)` | Routes through `omarchy-shell-ipc shell summon/hide` against the plugin's panel entry point. |
+| `withCurrentScreen(cb)` | Calls `cb` with the bar's currently-rendering screen. |
+| `tr/trp/hasTranslation` | Returns the key as-is; no i18n in v1. |
+| `openLauncher(...)` family | Stub — logs a warning. |
+
+## Known limitations
+
+- Plugin labels show raw translation keys for non-English locales.
+- Icon names not present in our compact `Icons` map render as `?`.
+- Plugins that declare only `desktopWidget` or `launcherProvider` and no
+  bar/panel/main do not appear in the Omarchy catalog.
+- Some plugins call `Color.mPrimary` for accent colors that don't perfectly
+  match Omarchy's theme palette; results are close but not pixel-identical.

 - `manifest.json` declares the plugin (`id: omarchy.bar`, `kind: bar`, `activation: persistent`) and points at `Bar.qml` as the entry point.
 - `Bar.qml` is Omarchy-owned bar engine code, loaded by the omarchy-shell host. Users should not edit it directly.
-- `bar-defaults.json` is the Omarchy-owned default layout and module settings.
 - `widgets/` holds first-party widgets — modular, interactive components shipped with Omarchy.
 - `common/` holds shared QML helpers (buttons, sliders, popup cards).
-- User overrides live in `~/.config/omarchy/bar.json` and are merged over defaults at runtime.
+- The bar receives its config from the host shell as a `barConfig` property; the host loads it from `~/.config/omarchy/shell.json` (or `shell-defaults.json` when the user has no file).
-- `omarchy-style-bar-position` updates only the user override file.
+- `omarchy-style-bar-position` updates only the user shell.json file.
 
 ## Customizing
 
-The bar reads `~/.local/share/omarchy/default/quickshell/omarchy-shell/plugins/bar/bar-defaults.json`, then deep-merges `~/.config/omarchy/bar.json` on top of it. Each `layout.{left,center,right}` entry is an object: at minimum `{ "id": "<widget>" }`, plus any inline settings the widget reads.
+The bar config lives under the `bar:` key of [`~/.config/omarchy/shell.json`](../../README.md#shelljson-shape). Out of the box the shell uses [`shell-defaults.json`](../../shell-defaults.json). Once you customize anything via `omarchy launch bar-settings` or by editing shell.json directly, your file is canonical — there is no deep-merge.
 
 Launch the visual editor with `omarchy launch bar-settings` (or run `omarchy-launch-bar-settings`) to reorder widgets, add/remove them, and tweak per-widget options without editing JSON by hand.
