## What's wrong

Documented behavior (shipped `agents/skills/omarchy/plugins.md`):

> Saving a file anywhere under `~/.config/omarchy/plugins/` reloads plugin code automatically. If a change somehow fails to apply, force a reload with `omarchy-shell shell rescanPlugins`.

For **service** plugins the code change never lands. The old compiled component keeps running and keeps answering IPC. The shell still logs `Local plugin changed, reloading: <plugin>`, so it looks like it worked. Neither a file save nor `omarchy-shell shell rescanPlugins` applies the change — only a full `omarchy restart shell` does.

`finishPluginReload()` in `/usr/share/omarchy/shell/shell.qml`:

```qml
if (typeof Qt.clearComponentCache === "function") Qt.clearComponentCache()
shell.pluginRegistry.rescan()
```

On Quickshell 0.3.1 (Arch package `quickshell 0.3.1-1`) `Qt.clearComponentCache` is `undefined`, so the guard skips the cache clear silently. `rescan()` then rebuilds the service from the **cached** component, so the instance is recreated from stale code.

## Steps to recreate

Service plugin with an IPC handler. I added one field (`rep: "A"`) to the JSON returned by `status()` in `Service.qml`.

1. Save `Service.qml`. Within a second:
   `journalctl --user -f` → `DEBUG qml: Local plugin changed, reloading: variable_5.smart-dim`
2. `omarchy-shell smart-dim status` → `rep` field **missing** (old code still answering)
3. `omarchy-shell shell rescanPlugins` → exits 0, still no `rep`
4. `omarchy restart shell` → `rep: "A"` present
5. Remove the field, save → log says reloading, `rep` **still present**
6. `omarchy restart shell` → `rep` gone

Both directions reproduce, so it is not an edit that silently failed to parse.

## Expected

Save (or `rescanPlugins`) applies the new service code, as documented. If `Qt.clearComponentCache` cannot be exposed, the reload path needs another way to invalidate the component cache.

## Workaround

Run `omarchy restart shell` after editing service plugin code. Worth noting in the plugin docs until this is fixed — right now the "reloading" log line and the `rescanPlugins` hint both suggest the change was applied when it was not.
