# DOM Reference: Search (`docs/DOM-SEARCH.md`)

Muse.ai global search (quick-search / command palette). Inspected live on bl via CDP
against the opm browser (warp-opm netns, CDP 127.0.0.1:9440) on 2026-10-04.
All selectors verified against the live DOM.

## 1. Search trigger — nav rail button

```javascript
document.querySelector('[data-testid="hatch-nav-search"]')
```

| Property | Value |
|---|---|
| Tag | `BUTTON` |
| `data-testid` | `hatch-nav-search` |
| `aria-label` | `"Search"` (stable — unlike `hatch-nav-chat`, no notification count) |
| Inner text | none (icon-only, SVG magnifier) |
| Geometry | x:0, y:136, 72×44 (left nav rail, second button) |
| Visibility | always present and visible on chat pages |

Parent chain (4 levels):

```
BUTTON[data-testid="hatch-nav-search"].group.relative.flex
└── DIV.hatch-dock-reveal-item
    └── DIV.my-auto.flex.shrink-0
        └── DIV.scrollbar-hide.flex.min-h-0   (nav rail container)
```

Nav rail button order (siblings, via `closest("div.my-auto")`):

```
hatch-nav-chat
hatch-nav-search            <-- search
hatch-nav-system-item-66656564   ("feed",  hex)
hatch-nav-system-item-6964656173 ("ideas", hex)
hatch-nav-system-item-676f616c73 ("goals", hex)
hatch-nav-system-item-6c696272617279 ("library", hex)
```

### Opening the dialog

| Method | Result |
|---|---|
| Real mouse click on the button (CDP `Input.dispatchMouseEvent` press+release at button center) | **Reliable — opens every time** |
| `Ctrl+K` via CDP `Input.dispatchKeyEvent` | Opens (verified multiple times; one flaky miss observed — prefer mouse click) |
| JS `button.click()` | **Unreliable** — Radix trigger appears to require trusted events; often silently does nothing |

---

## 2. Search dialog — quick-search frame

Opens as a Radix popover portal (direct child of a plain `DIV` under `BODY`):

```javascript
document.querySelector('[data-testid="hatch-quick-search-frame"]')
```

| Property | Value |
|---|---|
| Tag | `DIV` |
| `role` | `dialog` |
| `data-testid` | `hatch-quick-search-frame` |
| `data-slot` | `popover-content` |
| `data-state` | `"open"` when visible |
| `data-side` / `data-align` | `"bottom"` / `"center"` |
| `id` | `radix-_r_NN_` (unstable — generated per mount, do not match) |
| `tabindex` | `-1` |

Parent chain:

```
DIV#radix-_r_44_[data-testid="hatch-quick-search-frame"][role="dialog"]
└── DIV            (Radix portal wrapper)
    └── BODY
        └── HTML
```

Lifecycle:

- **On close (Escape): the dialog is fully removed from the DOM** — `querySelector`
  returns `null` (`ABSENT`), not merely hidden. Detection must handle absence, not
  just `offsetParent`.
- No `PRESENT_HIDDEN` state was observed; it is either open or gone.

---

## 3. Search input

```javascript
document.querySelector('[data-testid="command-palette-search-input"]')
```

| Property | Value |
|---|---|
| Tag | `INPUT` `type="text"` |
| `data-testid` | `command-palette-search-input` |
| `data-slot` | `command-input` |
| `cmdk-input` | `""` (boolean attribute — this is a cmdk command palette) |
| `role` | `combobox` |
| `aria-label` | `"Search Muse"` |
| `placeholder` | `"Search"` |
| `aria-autocomplete` | `"list"` |
| `aria-expanded` | `"true"` while open |
| `aria-controls` | `radix-_r_NN_` (unstable) |
| `aria-activedescendant` | set to the highlighted item's id on ArrowDown |
| `autocomplete` / `autocorrect` / `spellcheck` | `off` / `off` / `false` |

Behavior:

- **Auto-focuses when the dialog opens** (verified: `document.activeElement === input`
  immediately after open).
- **Do not touch the input via JS** (`focus()`, `click()`, native value setter):
  synthetic interaction on the input **closes the dialog** (verified twice).
  Type with trusted CDP key events instead (rawKeyDown → char → keyUp per char).

## 4. Results structure

### Listbox

```javascript
document.querySelector('[data-testid="hatch-quick-search-frame"] [role="listbox"]')
```

- `DIV[role="listbox"]`, cmdk-managed (class contains `cmdk-list-sizer`).
- Contains group headings + items.

### Result items

```javascript
document.querySelectorAll('[data-testid="hatch-quick-search-frame"] [data-testid="command-palette-item"]')
```

| Property | Value |
|---|---|
| Tag | `DIV` |
| `data-testid` | `command-palette-item` |
| `data-value` | **encodes the target** (see below) — the automation gold |
| Inner | `SPAN.bg-fill-secondary.flex` (icon, contains SVG) + `SPAN.flex.min-w-0` (text) |
| Text | thread title + snippet + relative time, `|`-separated |

### `data-value` formats (the important part)

| Prefix | Meaning | Example |
|---|---|---|
| `chat:main` | Main chat | `chat:main` |
| `chat:thread:<uuid>` | Sidechat thread — **the thread UUID is embedded** | `chat:thread:2e2c90a1-4b17-4590-b8ba-fb17d8018d36` |
| `chat:message:<msg-id>:<n>` | Individual message match inside a thread | `chat:message:assistant-msg-b2a4e27d-4970-8b1e-8863-a96ed0aa1401:20420` |

Search matches **both threads and individual messages**. A query like `"heartbeat"`
returned 12 results mixing `chat:thread:*` and `chat:message:*` values.

This is a ready-made thread-lookup mechanism: search for a sidechat name, read
`data-value`, extract the UUID — no title-matching or URL polling needed.

---

## 5. Groups

Initial (empty query) view:

```javascript
document.querySelectorAll('[data-testid="hatch-quick-search-frame"] [cmdk-group-heading]')
// => ["Recents"]
```

- One group heading: `"Recents"` (6 items observed).
- **After typing a query, group headings disappear** (`headings: []`) — filtered
  results render flat.

## 6. Filters / scopes

**None.** The dialog has no scope tabs, filter chips, or `role="tab"` elements:

```javascript
document.querySelectorAll('[data-testid="hatch-quick-search-frame"] [role="tab"], [data-testid*="tab"], [data-testid*="scope"], [data-testid*="filter"]')
// => []
```

Search is global over chats/messages with a single Recents group.

---

## 7. Empty / no-results state

For a query matching nothing (e.g. `"zzzznonexistentqueryzzzz"`):

- Dialog stays **open**, item count drops to `0`.
- Empty marker:

```html
<div data-slot="command-empty"
     class="text-footnote text-text-secondary flex h-12 items-center justify-center p-1.5 text-center"
     cmdk-empty=""
     role="presentation">No results found</div>
```

```javascript
document.querySelector('[data-testid="hatch-quick-search-frame"] [cmdk-empty]')
// innerText === "No results found"
```

Detection: `querySelector('[cmdk-empty]')` non-null, or item count `=== 0`.

---

## 8. Keyboard shortcuts

| Keys | Action | Verified |
|---|---|---|
| `Ctrl+K` | Open search dialog | Yes (CDP key events; one flaky miss — mouse click preferred) |
| `Cmd+K` | (likely macOS equivalent) | Not isolated — dialog was already open in test |
| `Escape` | Close dialog (removes it from DOM) | Yes |
| `ArrowDown` / `ArrowUp` | Move highlight; sets `aria-activedescendant` on input | Yes (`aria-activedescendant="radix-_r_19o_"`) |
| `Enter` | Activate highlighted result (navigate) | Expected combobox behavior — **not tested** (would navigate the browser away) |
| `/` | — | No effect on dialog state |

---

## 9. Testid inventory (search-related)

| `data-testid` | Tag | Purpose |
|---|---|---|
| `hatch-nav-search` | `BUTTON` | Nav rail trigger (`aria-label="Search"`) |
| `hatch-quick-search-frame` | `DIV` | Dialog root (`role="dialog"`, Radix popover) |
| `command-palette-search-input` | `INPUT` | Search box (`role="combobox"`, cmdk) |
| `command-palette-item` | `DIV` | Result row (`data-value` encodes target) |
| `hatch-chat-search-toolbar` | `DIV` | Seen once alongside an open dialog (context unclear — absent on main chat page; possibly panel inline search in some states) |
| `hatch-chat-search-field` | `DIV` | Same as above — observed but not mapped; treat as contextual |

---

## 10. Automation notes

1. **Open with a real mouse click**, not JS:
   ```javascript
   const b = document.querySelector('[data-testid="hatch-nav-search"]');
   const r = b.getBoundingClientRect();
   // CDP: Input.dispatchMouseEvent mousePressed + mouseReleased at (r.x + r.width/2, r.y + r.height/2)
   ```
   JS `.click()` on the trigger is unreliable (Radix wants trusted events).
2. **Never JS-touch the input.** `focus()`, `click()`, or the native value setter
   on `command-palette-search-input` closes the dialog. The input auto-focuses on
   open — just send trusted key events (`rawKeyDown` → `char` → `keyUp`).
3. **Closed === absent.** After Escape the dialog node is gone; check
   `querySelector(...) === null`, with optional chaining (`?.offsetParent`) —
   without `?.` a missing node throws and a truthy error string can false-positive
   an "open" check.
4. **Thread UUIDs for free.** `data-value="chat:thread:<uuid>"` on result items is
   the most reliable thread-identity source found so far — better than
   title-matching or post-send URL polling.
5. **No scopes to set.** One global search; filter client-side on `data-value`
   prefix (`chat:thread:` vs `chat:message:` vs `chat:main`).
6. **Ctrl+A via synthetic CDP events did not select input text** in one test
   (subsequent typing appended). For clearing, prefer Escape-and-reopen or
   repeated Backspace over select-all.
7. Dialog `id` (`radix-_r_NN_`) and `aria-activedescendant` values are generated
   per mount — never match on them.
