Post-Launch Verification

// scripts/post-launch-verify.ts
async function verifyProduction() {
  const checks = [
    { name: 'API Health', fn: checkApiHealth },
    { name: 'Database', fn: checkDatabase },
    { name: 'Transcription', fn: testTranscription },
    { name: 'Webhook', fn: testWebhook },
    { name: 'Metrics', fn: checkMetrics },
  ];

  console.log('Post-Launch Verification');
  console.log('========================');

  for (const check of checks) {
    try {
      await check.fn();
      console.log(`[PASS] ${check.name}`);
    } catch (error) {
      console.log(`[FAIL] ${check.name}: ${error.message}`);
    }
  }
}

async function checkApiHealth() {
  const response = await fetch('https://api.twinmind.com/v1/health', {
    headers: { 'Authorization': `Bearer ${process.env.TWINMIND_API_KEY}` },
  });
  if (!response.ok) throw new Error(`HTTP ${response.status}`);
}

async function testTranscription() {
  // Test with a known audio sample
  const client = getTwinMindClient();
  const result = await client.transcribe('https://example.com/test-audio.mp3');
  if (!result.id) throw new Error('No transcript ID returned');
}

// Run verification
verifyProduction();

Rollback Plan

## Rollback Procedure

### Immediate Rollback (< 5 minutes)
1. Trigger deployment rollback via CI/CD
2. Verify previous version is running
3. Confirm health checks passing

### Database Rollback (if needed)
1. Stop application traffic
2. Run migration rollback script
3. Verify data integrity
4. Resume traffic

### Communication
1. Update status page
2. Notify affected users
3. Create incident report

### Post-Rollback
1. Identify root cause
2. Create fix
3. Test in staging
4. Schedule re-deployment

Output

• Complete production checklist
• Pre-launch verification script
• Post-launch verification tests
• Rollback procedure

Error Handling

Issue	Impact	Mitigation
API key invalid	Service down	Verify key in staging first
Missing metrics	Blind spots	Test dashboards pre-launch
No rollback plan	Extended outage	Document and test rollback
Inadequate alerts	Delayed response	Test alert routes
