 ### Purpose
 
-Manages the Playwright browser session with persistent cookies/storage. Handles automated login, session verification, and 2FA/captcha detection.
+Manages the headless Playwright context used after an extension dump is imported. It accepts Reddit cookies, verifies account identity, and supplies authenticated context to the remaining browser-backed operations. It never performs login.

-### Login Flow
+### Import Flow
 
-```
-1. Navigate to Reddit login page
-2. Fill username and password
-3. Submit form
-4. Check for 2FA prompt
-   └─► If present: wait for manual input (with timeout)
-5. Check for captcha
-   └─► If present: log warning, wait
-6. Verify login success:
-   └─► Check for user menu indicator
-   └─► Check for profile avatar
-   └─► Fallback: API request to /api/me
-7. Save cookies to persistent directory
-8. On failure: capture debug screenshot
-```
+The dashboard validates a combined extension dump, verifies Matrix with `whoami`, imports Reddit cookies, verifies Reddit identity, and only then marks the shared account gate authenticated.
 
 ### Session Persistence
 
 - Cookies and storage are saved to `config.browser.userDataDir`
 - Subsequent launches restore the session automatically
-- Session expires when Reddit cookies expire (requires re-login)
+- Session expiry pauses account work until a fresh extension dump is imported
 
 ### Dependencies
 
-- `Config` - Credentials, headless mode, user data dir
-- `Logger` - Login progress, errors

-## MessagePage
-
-**File**: `src/browser/message-page.ts`  
-**Lines**: 560  
-**Responsibility**: Reddit DM compose page automation
-
-### Purpose
-
-Automates the Reddit DM compose page: filling recipient/subject/body fields, handling shadow DOM components, submitting messages, and verifying success.
-
-### Public Methods
-
-```typescript
-class MessagePage {
-  constructor(
-    private browser: BrowserClient,
-    private config: Config,
-    private logger: Logger
-  )
-
-  /** Send a DM to a recipient */
-  sendDM(recipient: string, subject: string, body: string): Promise<boolean>
-
-  /** Check if recipient field shows an error */
-  hasRecipientError(page: Page): Promise<boolean>
-}
-```
-
-### Shadow DOM Handling
-
-Reddit's compose form uses `faceplate-*` web components:
-
-```javascript
-// Fill shadow DOM input fields
-page.evaluate(({ selector, value }) => {
-  const shadowInput = document.querySelector(`${selector} input`);
-  if (shadowInput) {
-    shadowInput.value = value;
-    shadowInput.dispatchEvent(new Event('input', { bubbles: true }));
-  }
-}, { selector: 'faceplate-textarea[name="body"]', value: body });
-```
-
-### Dry Run Mode
-
-When `config.dryRun` is enabled:
-- All fields are filled as normal
-- Submit button is NOT clicked
-- Message is logged but not sent
-- Returns `true` (simulates success)
-
-### Dependencies
-
-- `BrowserClient` - Playwright page access
-- `Config` - Dry run mode
-- `Logger` - Send activity
+- `Config` - Persistent session directory
+- `Logger` - Import verification progress and errors
