## System details

Intel i9-12900H, Intel Iris Xe + NVIDIA RTX A3000 Laptop, Omarchy 4.0.4-1, Quickshell 0.3.1 (Arch).

## What happened

A third-party plugin that is both a `service` and a `bar-widget` ends up with a live service and no bar widget. The slot is in `~/.config/omarchy/shell.json`, but nothing is drawn and the service has no widget instance. Reloading the plugin does not compile the widget file: a syntax error in that file produces no load error.

Reproduced with [OmaStats 1.4.0](https://github.com/crmne/omastats) (`crmne.omastats`, `keepLoaded: true`, commit `61878e8`). The plugin is enabled and its entry is in the right section of the bar.

The service is up. Its sampler is a child of the shell, and IPC answers:

```
omarchy-shell crmne.omastats status
{"ready":true,"seq":2606,"cpu":17.9,"cpuTemp":56,"memoryPercent":17.1,"download":1641668.75,"upload":31292.38,"gpu":null,"battery":24,"error":""}
```

The widget is not:

```
omarchy-shell crmne.omastats locate
[]

omarchy-shell crmne.omastats show cpu
no-widget
```

`no-widget` is what `OmaStatsService.qml` returns when no bar instance has called `registerInstance()`. The right-hand side of the bar shows the neighboring icons and no CPU / memory / network readouts in the OmaStats slot.

`journalctl --user -t omarchy-shell` has `Local plugin changed, reloading: crmne.omastats` and never `Plugin widget crmne.omastats failed`. A `console.warn` added to `Component.onCompleted` in `OmaStatsWidget.qml` never showed up after that reload, so the item is not constructed.

The widget file itself compiles. In a separate Quickshell process, `Qt.createComponent("…/OmaStatsWidget.qml", Component.PreferSynchronous)` returns status `1` (Ready) and an empty error string.

Saving a deliberate syntax error into `OmaStatsWidget.qml` still only logs the reload line. There is no `Plugin widget crmne.omastats failed:` warning. The diagnostic edit was reverted; `git diff` in the plugin checkout is empty. So the running shell is not compiling that file on reload.

## Expected

The bar widget is created, draws its readouts, and `locate` lists the instance. A syntax error in the widget QML is reported with `Plugin widget <id> failed`.

## Where this diverges in the shell

`ensureService()` compiles the service with `Component.PreferSynchronous`, and that path works. The sampler stays up across reloads because the manifest sets `keepLoaded: true`.

`loadPluginWidget()` compiles the bar widget with `Component.Asynchronous` and only calls `barWidgetRegistry.register()` from `finalize()`. Neither the Ready path nor the Error path is visible for this plugin: the widget is never registered, and a file that cannot compile does not log the failure.

This is not #11796. That report is a widget that does mount, whose `bar.shell.serviceFor()` returns null. Here the widget object is never constructed.

## Steps

1. Omarchy 4.0.4-1, stock `omarchy.bar`.
2. `omarchy plugin add https://github.com/crmne/omastats.git --enable`
3. Confirm the entry is in `bar.layout` and the sampler process is running.
4. `omarchy-shell crmne.omastats status` returns data. `locate` returns `[]`. `show cpu` returns `no-widget`. The bar slot is empty.
5. Put a syntax error in `~/.config/omarchy/plugins/crmne.omastats/OmaStatsWidget.qml` and save. The journal logs the reload and does not log `Plugin widget crmne.omastats failed`.
