### System details

Framework Laptop 13 (AMD Ryzen AI 9 HX 370 / Radeon 890M), Omarchy 4.0.2-1, linux 7.1.9-arch1-2, Hyprland 0.56.2, quickshell 0.3.1-1

### What's wrong?

`omarchy bar set --json` cannot persist **JSON array** widget settings. The command reports success, but a one-element array is stored as a string, and a multi-element array is rejected by Quickshell IPC as extra arguments.

This matters for `omarchy.tray`: `pinned` / `hidden` are arrays. `Tray.qml` only honors an array:

```qml
readonly property var pinnedIds: settings.pinned instanceof Array ? settings.pinned : []
```

So `omarchy bar set omarchy.tray pinned '["steam"]' --json` looks like it worked and does nothing: Steam stays in the hover drawer. Pinning from the chevron manage popup works, because that path writes a real array in-process via `updateEntryInline`.

#### Steps

With `omarchy.tray` on the bar and Steam running (or any SNI id):

```bash
omarchy bar set omarchy.tray pinned '["steam"]' --json
# → Set pinned on omarchy.tray
```

`~/.config/omarchy/shell.json` then has:

```json
{ "id": "omarchy.tray", "pinned": "steam" }
```

Expected:

```json
{ "id": "omarchy.tray", "pinned": ["steam"] }
```

Direct IPC (same result):

```bash
omarchy-shell shell setBarWidget omarchy.tray pinned '["steam"]' '{}'
# stored "steam" (string)

omarchy-shell shell setBarWidget omarchy.tray pinned '["steam","foo"]' '{}'
# Too many arguments provided (4 required but 5 were provided.)
# Function definition: function setBarWidget(id: string, key: string, valueJson: string, selectorJson: string): string

omarchy-shell shell setBarWidget omarchy.tray pinned '{"a":1}' '{}'
# stored {"a":1}  (object, correct)

omarchy-shell shell setBarWidget omarchy.tray pinned '300' '{}'
# stored 300  (number, correct)
```

Objects, numbers, and bools round-trip. Arrays do not.

#### Where it breaks

`omarchy-bar` `cmd_set` is fine: `jq --argjson` emits `["steam"]`, then:

```bash
omarchy-shell shell setBarWidget "$id" "$key" "$value_json" "$(placement_json)"
```

`omarchy-shell` forwards that to `qs ipc call`. `shell.qml` `setBarWidget` is typed with `valueJson: string` and does `JSON.parse(valueJson)`.

A JSON array argument is not one string to parse. A one-element array is coerced into the string `"steam"` (parse succeeds, wrong type). Two or more elements become extra IPC arguments.

The chevron Pin button never hits this path (`persistTrayState` → `updateEntryInline` with a JS array), which is why the UI works and the documented CLI does not.

Workaround: edit `~/.config/omarchy/shell.json` so `pinned` is an array, or pin from the chevron popup.

`omarchy-debug --no-sudo --print` was collected locally; this is a CLI/IPC bug, not a hardware one.
