Configuration (Side Panel Fields)

Storage Behavior

• chrome.storage.session — runtime state (steps, OAuth link, email, password, callback URL, tab info). Cleared when browser closes.
• chrome.storage.local — persistent config (CPA URL, password, mail service, Inbucket settings). Survives browser restarts.

The 9-Step Workflow

Step 1: Get OAuth Link

Opens CPA panel → finds Codex OAuth card → clicks login → extracts authorization URL → saves to OAuth field.

Step 2: Open Signup

Opens the OAuth authorization link → locates and clicks Sign up / Register / 创建账户 button.

Step 3: Fill Email / Password

Fills registration form with email and password. Auto-generates strong password if field is blank. Actual password used is written back to the sidebar.

Step 4: Get Signup Code

Polls the configured mailbox for a 6-digit OTP. Handles Operation timed out errors by auto-clicking retry.

Email matching rules:

• Sender contains: openai, noreply, verify, auth, duckduckgo, forward
• Subject contains: verify, verification, code, 验证, confirm

Step 5: Fill Name / Birthday

Generates random name and birthday. Handles two page variants:

• Birthday mode: fills year/month/day
• Age mode: fills input[name='age'] directly

Step 6: Login via OAuth

Re-fetches latest CPA OAuth link, then logs in with the newly registered account.

Step 7: Get Login Code

Same as Step 4 but with login-specific keyword matching.

Step 8: Manual OAuth Confirm (Auto-attempts)

• Locates the "Continue/Authorize" button on the OAuth consent page
• Uses Chrome debugger API to dispatch input events for the click
• Monitors chrome.webNavigation.onBeforeNavigate for localhost callback
• Only accepts: http(s)://localhost:<port>/auth/callback?code=...&state=...
• Timeout: 120 seconds

Step 9: CPA Verify

• Validates callback URL has both code and state params
• Submits callback to CPA panel
• Waits for exact 认证成功！ status badge
• Closes residual http://localhost:1455/auth* tabs

Auto Mode

Click Auto in the sidebar to run all 9 steps sequentially for N rounds (set by the number input).

Auto flow:
  Step 1 → Step 2 → [Duck email auto-fetch, retry up to 5x]
    ↓ (if Duck fails) → Pause, wait for manual email input → Continue
  Step 3 → Step 4 → Step 5 → Step 6 → Step 7 → Step 8 → Step 9
  → Repeat for N rounds

Resuming After Pause

When Auto is paused and you reopen the sidebar, two options appear:

• 重新开始 — Reset progress, start new round from Step 1
• 继续当前 — Treat completed/skipped steps as done, resume from first unhandled step

Key Code Patterns

Waiting for Elements (content/utils.js pattern)

// Wait for a DOM element with stop-signal support
async function waitForElement(selector, timeout = 30000) {
  const start = Date.now();
  while (Date.now() - start < timeout) {
    // Check stop signal from background
    const { stopFlow } = await chrome.storage.session.get('stopFlow');
    if (stopFlow) throw new Error('STOPPED');

    const el = document.querySelector(selector);
    if (el) return el;
    await new Promise(r => setTimeout(r, 500));
  }
  throw new Error(`Timeout waiting for: ${selector}`);
}

Reading/Writing Session State (background.js pattern)

// Save OAuth link to session
await chrome.storage.session.set({ oauthLink: extractedUrl });

// Read current email and password
const { currentEmail, currentPassword } = await chrome.storage.session.get([
  'currentEmail',
  'currentPassword'
]);

// Update step status
await chrome.storage.session.set({
  stepStatus: { ...existingStatus, step3: 'done' }
});

Sending Messages to Content Scripts

// background.js → content script
const [tab] = await chrome.tabs.query({ url: '*://chat.openai.com/*' });
const result = await chrome.tabs.sendMessage(tab.id, {
  action: 'FILL_EMAIL',
  email: 'user@duck.com',
  password: 'GeneratedPass1!'
});

Inbucket Mailbox Polling (content/inbucket-mail.js pattern)

// Only targets unread messages
const unseenEntries = document.querySelectorAll('.message-list-entry.unseen');
// From 2nd poll onwards, click the refresh button
if (pollCount > 1) {
  const refreshBtn = document.querySelector('[data-action="refresh"]');
  if (refreshBtn) refreshBtn.click();
  await sleep(1000);
}
// After reading, delete the email to avoid re-matching

Chrome Debugger Click (content/signup-page.js pattern)

// Attach debugger to tab for synthetic input events
await chrome.debugger.attach({ tabId }, '1.3');
const { x, y } = buttonBounds;
await chrome.debugger.sendCommand({ tabId }, 'Input.dispatchMouseEvent', {
  type: 'mousePressed', x, y, button: 'left', clickCount: 1
});
await chrome.debugger.sendCommand({ tabId }, 'Input.dispatchMouseEvent', {
  type: 'mouseReleased', x, y, button: 'left', clickCount: 1
});
await chrome.debugger.detach({ tabId });

OAuth Callback Listener (background.js pattern)

chrome.webNavigation.onBeforeNavigate.addListener(async (details) => {
  // Only main frame, only the auth tab
  if (details.frameId !== 0) return;
  if (details.tabId !== authTabId) return;

  const url = details.url;
  // Strict: must be localhost /auth/callback with code + state
  if (/^https?:\/\/localhost:\d+\/auth\/callback\?/.test(url)) {
    const parsed = new URL(url);
    if (parsed.searchParams.get('code') && parsed.searchParams.get('state')) {
      await chrome.storage.session.set({ callbackUrl: url });
    }
  }
});

Stop Signal Broadcasting

// From sidebar: send stop
await chrome.runtime.sendMessage({ action: 'STOP_FLOW' });

// In background.js: set flag and broadcast to all content scripts
await chrome.storage.session.set({ stopFlow: true });
const tabs = await chrome.tabs.query({});
for (const tab of tabs) {
  chrome.tabs.sendMessage(tab.id, { action: 'STOP_FLOW' }).catch(() => {});
}

DuckDuckGo Email Auto-Fetch

// Triggered by sidebar "Auto" button next to Email field
// content/duck-mail.js opens:
// https://duckduckgo.com/email/settings/autofill
// Looks for existing private address or generates new one
const generateBtn = document.querySelector('[data-testid="generate-address"]');
if (generateBtn) generateBtn.click();
await waitForElement('.address-display');
const newAddress = document.querySelector('.address-display').textContent.trim();

Persistent Config (chrome.storage.local)

// Save config
await chrome.storage.local.set({
  cpaUrl: 'https://your-host/management.html#/oauth',
  mailService: 'Inbucket',        // '163 Mail' | 'QQ Mail' | 'Inbucket'
  inbucketHost: 'your-inbucket-host',
  inbucketMailbox: 'tmp-mailbox',
  customPassword: '',              // empty = auto-generate
});

// Load config
const config = await chrome.storage.local.get([
  'cpaUrl', 'mailService', 'inbucketHost', 'inbucketMailbox', 'customPassword'
]);

Troubleshooting

Step 8 timeout (120s exceeded)

• The OAuth consent page structure may have changed
• Manually click the "Continue" button and observe what URL the redirect hits
• Check the button selector in content/signup-page.js

Step 4/7: OTP never arrives

• Verify the mail service tab is open and logged in before running
• For Inbucket: confirm https://<host>/m/<mailbox>/ is accessible
• Check sender/subject filters — OpenAI sometimes changes sender addresses
• For QQ/163: ensure the webmail tab is the correct account

Duck email auto-fetch fails (retries 5x then pauses)

• DuckDuckGo extension must be installed and logged in
• The autofill settings page URL may have changed
• Fall back to manual email entry in the sidebar

CPA panel not detected (Step 1/9)

• Confirm your CPA URL matches management.html#/oauth path structure
• The content/vps-panel.js selectors are hardcoded to a specific panel layout
• Try running Step 1 manually to see console errors

"Operation timed out" on signup (Step 4)

• This is handled automatically — the script clicks the retry button and re-submits
• If it loops, the OpenAI signup endpoint may be rate-limiting your IP

Tab cleanup issues

• Old localhost tabs accumulate: Step 9 only cleans http://localhost:1455/auth*
• If your CPA uses a different port, update the cleanup filter in background.js

Recommended Workflow

1. Configure sidebar (CPA URL, Mail service, credentials)
2. Run Step 1 manually → verify OAuth link appears
3. Run Steps 2-4 manually → confirm email + OTP flow works
4. If successful, enable Auto with N=5 for a test batch
5. Scale up rounds once flow is stable

Note: Always test single-step flow before enabling Auto. The most fragile steps are Step 8 (OAuth consent click) and Step 4/7 (OTP timing). Use Inbucket for most reliable OTP delivery in automated runs.
