## Pre-Launch Verification Script

```bash
#!/bin/bash
set -euo pipefail
# pre-launch-check.sh

echo "TwinMind Production Pre-Launch Check"
echo "====================================="

# Check environment
echo -n "Checking NODE_ENV... "
if [ "$NODE_ENV" = "production" ]; then
  echo "OK (production)"
else
  echo "WARNING: NODE_ENV=$NODE_ENV"
fi

# Check API key
echo -n "Checking API key... "
if [ -n "$TWINMIND_API_KEY" ]; then
  PREFIX=${TWINMIND_API_KEY:0:10}
  echo "OK ($PREFIX...)"
else
  echo "FAIL: TWINMIND_API_KEY not set"
fi

# Test API connectivity
echo -n "Testing API connectivity... "
HEALTH=$(curl -s -o /dev/null -w "%{http_code}" \
  -H "Authorization: Bearer $TWINMIND_API_KEY" \
  https://api.twinmind.com/v1/health)
if [ "$HEALTH" = "200" ]; then  # HTTP 200 OK
  echo "OK"
else
  echo "FAIL: HTTP $HEALTH"
fi

# Check webhook secret
echo -n "Checking webhook secret... "
if [ -n "$TWINMIND_WEBHOOK_SECRET" ]; then
  echo "OK"
else
  echo "WARNING: TWINMIND_WEBHOOK_SECRET not set"
fi

# Check encryption key
echo -n "Checking encryption key... "
if [ -n "$TWINMIND_ENCRYPTION_KEY" ]; then
  KEY_LEN=${#TWINMIND_ENCRYPTION_KEY}
  if [ "$KEY_LEN" -ge 64 ]; then
    echo "OK (256-bit)"  # 256 bytes
  else
    echo "WARNING: Key too short"
  fi
else
  echo "WARNING: TWINMIND_ENCRYPTION_KEY not set"
fi

# Check database
echo -n "Checking database... "
if [ -n "$DATABASE_URL" ]; then
  echo "OK"
else
  echo "FAIL: DATABASE_URL not set"
fi

echo ""
echo "Pre-launch check complete."
```

## Post-Launch Verification

```typescript
// 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

```markdown
## 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 |

## Next Steps
For upgrading between tiers, see `twinmind-upgrade-migration`.

## Instructions

1. Assess the current state of the deployment configuration
2. Identify the specific requirements and constraints
3. Apply the recommended patterns from this skill
4. Validate the changes against expected behavior
5. Document the configuration for team reference

## Examples

**Basic usage**: Apply twinmind prod checklist to a standard project setup with default configuration options.

**Advanced scenario**: Customize twinmind prod checklist for production environments with multiple constraints and team-specific requirements.
