# muse.ai DOM Index — Master Reference

> **Box is the main surface.** All operator work goes through Box (box.muse-dev.online). The web UI, `box` CLI, and agents share the same API endpoints. No UI-only powers.

> **Entry point for all muse.ai DOM automation work.**
> Read this first. It indexes every `data-testid`, every key selector, every
> automation recipe, and flags known contradictions between the detailed docs.
>
> Rule of thumb from the field: prefer `data-testid` > `aria-label` > `role`/`id`
> > class names. Tailwind classes shift with deploys; testids don't.

## 2. Master `data-testid` Table (deduplicated)

`Docs` column: **C** = CHAT-PANEL, **M** = MESSAGES, **P** = PAGE-STRUCTURE.

### Chat core (panel toggle + creation)

| testid | Tag | Purpose | Docs |
|---|---|---|---|
| `hatch-chat-switcher-trigger` | `BUTTON` | Panel open/close **toggle**. Inner text is the **current thread title** (not `Chats`) — never match by text. Never blind-click — check compose first | C, P |
| `hatch-side-chats-open-drag-handle-divider-line` | `DIV` | Divider for the closed-panel drag handle; absent when panel is open (verified 2026-10-04, all nodes) | P |
| `hatch-chat-switcher-icon-knockout` | `SPAN` | Icon wrapper inside switcher | C, P |
| `hatch-chat-switcher-navigation-icon` | `SPAN` | Hamburger SVG inside switcher | C, P |
| `hatch-chat-leading-controls` | `DIV` | Top-left container holding the switcher | C, P |
| `hatch-chat-compose` | `BUTTON` | **New side chat `+`**. Icon-only (`aria-label="New side chat"`). Exists **only when panel is open** → the canonical "ready" signal | C, M, P |
| `hatch-chat-nav-fade` | `DIV` | Nav fade effect | C, P |
| `hatch-chat-search-toolbar` | `DIV` | Panel search toolbar (60px) | C, P |
| `hatch-chat-search-field` | `DIV` | Search input container | C, P |
| `hatch-side-chats-options` | `BUTTON` | "Side chat options" three-dots dropdown | C, P |
| `hatch-chat-switcher-unread-indicator` | — | Unread badge on switcher | M |

### Sidechat panel tree

| testid | Tag | Purpose | Docs |
|---|---|---|---|
| `hatch-side-chats-panel-shell` | `DIV` | Outer shell, **always in DOM**, `innerHTML === ""` when closed, 240px fixed | C, P |
| `hatch-side-chats-panel-sliding-surface` | `DIV` | Sliding animation surface (open only) | C, P |
| `hatch-side-chats-panel-content` | `DIV` | Content wrapper — presence = panel open | C, P |
| `hatch-side-chats-open-drag-handle` | `DIV` | Panel resize handle | C, P |
| `hatch-thread-row` | `DIV[role=button]` | **Every** chat row (Main + sidechats). Not links — click to navigate. Active row has `aria-current="page"` | C, P |
| `hatch-side-chat-unread-indicator` | — | Per-chat unread indicator | P |
| `active-side-chat-load-more-sentinel` | `DIV` | Infinite-scroll sentinel at list end | C, P |

| `hatch-dock-rail-divider` | `SPAN` | Rail divider | P |
| `hatch-nav-chat` | `A` | **Chat section link** (`href="/"`). `aria-label` is dynamic (`Chat` / `Chat, N notifications`) — match testid, never exact aria-label. `aria-current="page"` when Chat active. **The reliable chat activator** | C, M, P |

---

## 3. Non-`testid` Selectors (equally load-bearing)

| Selector | Purpose | Doc |
|---|---|---|
| `textarea[aria-label="Message"]` | Message composer input. Fallbacks: `[contenteditable="true"]`, `textarea[placeholder*="Message"]`, `div[role="textbox"]` | M |
| `button[aria-label*="send" i]` | Send button (no testid, SVG-only). Fallback: Enter keydown on input | M |
| `#hatch-chat-scroll` | Message scroll container | M |
| `div[role="log"][aria-label="Chat messages"]` | Message list | M |
| `[data-message-id]` | Each message. `assistant-msg-<uuid>` = assistant, bare `<uuid>` = user | M |
| `button[aria-label="Back to main chat"]` | **Primary main-chat affordance** from any thread state (`/thread/<uuid>` and `/thread/new`), panel open or closed. Verified 2026-10-04 on all 3 nodes | P (§2.7) |
| Exact-text `Main chat` element | Main-chat navigation target — match `(e.innerText).trim() === 'Main chat'` on `button, [role="button"]`, never substring | P (§2.7), AGENTS.md |

---

## 4. Quick-Reference Automation Recipes

### 4a. Activate chat (recover from ANY state) — replaces Ctrl+J

```javascript
// Priority: compose (fast path) → switcher → nav-chat (stripped-state recovery)
function ensureChatActive() {
  if (document.querySelector('[data-testid="hatch-chat-compose"]')) return true; // already ready
  const sw = document.querySelector('[data-testid="hatch-chat-switcher-trigger"]');
  if (sw) { sw.click(); return "clicked-switcher"; }                            // closed panel
  const nc = document.querySelector('[data-testid="hatch-nav-chat"]');
  if (nc) { nc.click(); return "clicked-nav-chat"; }                            // /thread/new stripped
  return false; // not on a chat page at all — abort
}
// Poll up to ~20s, then verify compose exists before proceeding.
```

**Why not Ctrl+J:** it needs keyboard focus, which stripped states (`/thread/new`)
lack — the keystroke goes nowhere. DOM clicks don't need focus. (Commit `72574ba`.)

### 4b. Detect current state (one-liner)

```javascript
(() => {
  const url = window.location.href, title = document.title;
  const q = s => !!document.querySelector(s);
  if (title === 'muse.ai') return 'LANDING';
  if (url.includes('/thread/new')) return 'THREAD_NEW_STRIPPED';
  if (url.includes('/thread/')) return q('[data-testid="hatch-chat-switcher-trigger"]') ? 'SIDECHAT' : 'THREAD_NEW_STRIPPED';
  if (url === 'https://muse.ai/') {
    if (!q('[data-testid="hatch-chat-switcher-trigger"]')) return 'UNKNOWN_NO_SWITCHER';
    return q('[data-testid="hatch-chat-compose"]') ? 'MAIN_PANEL_OPEN' : 'MAIN_PANEL_CLOSED';
  }
  return 'UNKNOWN';
})()
```

State table: LANDING · MAIN_PANEL_CLOSED · MAIN_PANEL_OPEN · THREAD_NEW_STRIPPED
(`/thread/new`, no switcher) · SIDECHAT (`/thread/<uuid>`). Full matrix: PAGE-STRUCTURE §1.

### 4c. Create sidechat (robust)

```
1. ensureChatActive() (§4a) — poll ≤20s, abort if false
2. Verify: !!document.querySelector('[data-testid="hatch-chat-compose"]')
3. Click compose
4. Poll window.location.href ≤15s for "/thread/"  →  /thread/new (placeholder)
5. Send first message directly (browser is on the new sidechat)
6. Poll href for /thread/<uuid> to capture the durable thread URL
```

### 4d. Send a message

```
1. ta = document.querySelector('textarea[aria-label="Message"]') (+ fallbacks)
2. Verify ready: ta.offsetParent !== null && !ta.disabled && !ta.readOnly
3. ta.focus(); document.execCommand('insertText', false, message)
   (React fallback: native value setter + bubbling 'input' event)
4. send = [...document.querySelectorAll('button')].find(b => b.getAttribute('aria-label')?.toLowerCase().includes('send'))
   → send.click()  else Enter-keydown on ta
5. If streaming: [data-testid="hatch-composer-stop-button"] appears; wait for it to vanish
```

### 4e. Open a specific sidechat / go to main chat

```javascript
// By title (rows are DIV[role=button], NOT links — no hrefs exist):
const row = [...document.querySelectorAll('[data-testid="hatch-thread-row"]')]
  .find(r => r.querySelector('span[title]')?.getAttribute('title') === '<title>');
row?.click();
// Main chat: exact text match, never substring:
const main = [...document.querySelectorAll('button, [role="button"]')]
  .find(e => (e.innerText || '').trim() === 'Main chat');
main?.click();
```

### 4f. Check for blocking approval dialogs

Text-based (no stable testids observed). See APPROVALS-SPEC for the full contract:
- Body text contains `Allow` + `to share` in an element < 500 chars, **and** an IPv4 is present
- Trusted IPs (`34.139.37.135`, `100.123.153.75`, `100.81.31.9`) → auto-click `allow once`/`allow`
- Anything else → print `APPROVAL_NEEDED`, exit **2**, do NOT click

## 5. Known Contradictions (resolved here — detail docs may lag)

| # | Conflict | Resolution (this index wins) |
|---|---|---|
| 1 | PAGE-STRUCTURE §7.1 and §2.7 recommend **Ctrl+J** as "proven reliable" for main-chat navigation / state recovery | **Superseded.** Ctrl+J needs keyboard focus; stripped states lack it. Use the §4a click sequence (`hatch-nav-chat` → switcher). CHAT-PANEL §6.1 already agrees Ctrl+J is unreliable |
| 2 | PAGE-STRUCTURE §1.3 "Recovery: Send Ctrl+J" from `/thread/new` | **Use `button[aria-label="Back to main chat"]` click** or `hatch-nav-chat` click instead |
| 3 | `/thread/new` title: MESSAGES §5 and PAGE-STRUCTURE §1.3 say `Muse`; a 2026-10-04 probe table said `Chat — …` | **Docs consensus: `Muse`.** Treat title as advisory only — detect via URL + switcher absence (§4b), never title alone |
| 4 | "Sidechat create navigates to main first" (older code comment) | **Unnecessary.** The ready state for *create* is any chat-active view; `hatch-nav-chat` recovery lands on main anyway |
| 5 | CHAT-PANEL / older notes describe switcher text as `Chats` (or `Chats\nUnread chats…`) | **Thread title.** Verified 2026-10-04 on all nodes: switcher innerText = `<current thread title>\nOpen chat and side chats`. Never match the switcher by text |

---

## 6. Gaps — Unmapped Territory

1. **`hatch-inline-approval-card` structure** — testid + surface text documented (PAGE-STRUCTURE §6, this index §2), full structure deferred to inspector 3/5 in DOM-APPROVALS-SPEC.md.
2. **Feed / Ideas / Goals / Library pages** — dock testids listed, page content unmapped.
3. **Search overlay** (`hatch-nav-search` target) — trigger documented in DOM-SEARCH.md; result-row interactions unmapped.
4. **OTP / account-selection states** — body-text markers known (`To log in, enter the code`, `Your email matches multiple accounts`), DOM unmapped. Automation should abort to human here.
5. **`cmd_sidechat_main`'s exact-text `Main chat` lookup** — documented in AGENTS.md and §3/§4e here, no DOM-doc section.
6. **Partial-load state** (title `Muse`, ~21 buttons, transient) — mentioned in MESSAGES §5, no recovery procedure beyond "navigate to `/` and re-probe".
7. **Message read-back verification selectors** — MESSAGES §3 covers extraction; the `dm.py` tail-match verification loop is code-only.
8. **`/tmp` script collisions between inspectors** — two inspectors overwrote each other's `/tmp/cdp_eval.py` on bl mid-task (2026-10-04). Namespace throwaway scripts per-inspector (e.g. `/tmp/cdp_eval_<area><n>.py`).

> Resolved 2026-10-04: `button[aria-label="Back to main chat"]` now has a
> dedicated section in PAGE-STRUCTURE §2.7 (was gap #1 in the previous index).

## 7. Maintenance

- This index is the **entry point**; detail docs hold the deep dumps. When a selector changes, update the detail doc **and** the tables/recipes here.
- Contradiction rule: **newer verified probe beats older doc text**; record the resolution in §5 with the commit or date.
- "Last verified" in §1 is per-doc. If you re-probe a doc's selectors, bump its date.
- Prefer adding a dated note over rewriting history — these docs are also an audit trail.
- 2026-10-04 regeneration: document map now covers all 10 `DOM-*.md` files
  (was 4); master table carries the two new testids
  (`hatch-side-chats-open-drag-handle-divider-line`, `hatch-inline-approval-card`)
  and the switcher-text + dock-rail-divider corrections. When a new DOM doc
  lands, add its row to §1 and its testids to §2 in the same commit.
