| 21 | SMS Reconciliation Command | ✅ |
| 22 | Redis Session Store + Introspection | ✅ |
| 23 | Docker Deployment for Go Service | ✅ |
| 24 | Tenant Rollout (SHADOW) | ✅ |
| 25 | Tenant Rollout (ON) | ✅ |
| 26 | Global Rollout | ✅ |

### What's Ready for Production

The entire migration is **COMPLETE**. The system is ready for production with:

1. **OFF mode** - Laravel sends SMS (original behavior)
2. **SHADOW mode** - Laravel sends + Go receives dry-run (for testing)
3. **ON mode** - Go sends + Laravel fallback (production goal)

### Recommended Next Actions

Since all technical steps are done, what remains is **operational**:

1. **Enable ALLOW_REAL_SEND=true** in production Go service when ready to actually send SMS
2. **Start with SHADOW mode** for pilot tenants to validate logs match
3. **Run `sms:reconcile`** regularly to monitor for discrepancies
4. **Promote to ON mode** using `messaging:rollout promote --tenant=X`
5. **Global rollout** when all tenants are stable: `messaging:rollout global --mode=ON`

Would you like me to:
1. Create any additional monitoring/alerting commands?
2. Add more comprehensive tests?
3. Document the operational procedures?
4. Something else?

## Database Schema

### New Tables Created

**1. `feature_flags`** - Tenant-level feature control
```sql
CREATE TABLE feature_flags (
    id BIGINT UNSIGNED PRIMARY KEY AUTO_INCREMENT,
    tenant_id BIGINT UNSIGNED NULL,          -- NULL = global default
    feature_name VARCHAR(100) NOT NULL,
    mode ENUM('OFF', 'SHADOW', 'ON') DEFAULT 'OFF',
    created_at TIMESTAMP,
    updated_at TIMESTAMP,
    UNIQUE KEY (tenant_id, feature_name)
);
```

**2. `go_sms_logs`** - Go service idempotency store

## API Endpoints

### Go Messaging Service

**Health Check:**
```
GET http://messaging-service:8080/health
Response: {"status": "healthy"}
```

**Send Batch (Internal):**
```
POST http://messaging-service:8080/internal/v1/sms/send-batch
Headers:
  X-Internal-API-Key: <INTERNAL_API_KEY>
  Content-Type: application/json

Body:
{
  "tenant_id": 1,
  "campaign_id": 123,
  "messages": [
    {
      "message_uuid": "uuid-here",
      "recipient": "+1234567890",
      "body": "Hello",
      "provider": "twilio"
    }
  ],
  "dry_run": false
}

Response:

## Feature Flag Modes

| Mode | Laravel Sends | Go Sends | Go dry_run | Quota Decrement | Use Case |
|------|---------------|----------|------------|-----------------|----------|
| **OFF** | YES | NO | N/A | Laravel | Default, legacy behavior |
| **SHADOW** | YES | YES | true | Laravel only | Testing Go without risk |
| **ON** | Fallback only | YES | false | Go only | Production target |

### Mode Behavior Details

**OFF Mode:**
- Laravel handles all SMS sending
- Go service is not called
- Original application behavior

**SHADOW Mode:**
- Laravel sends SMS first (real delivery)
- Go service receives same request with `dry_run=true`
- Go logs to `go_sms_logs` but doesn't call providers
- Allows comparing logs for discrepancies

**ON Mode:**
- Go service sends SMS first (real delivery)
- If Go fails/times out/circuit open → Laravel fallback
- Laravel logs Go results to `sms_logs` with `source='go'`
- Quota decremented only for accepted messages

---

## Circuit Breaker

The circuit breaker protects against Go service failures:

| State | Behavior |
|-------|----------|
| **Closed** | Requests go to Go service normally |
| **Open** | Requests skip Go, use Laravel fallback |
| **Half-Open** | Allow 1 test request to check recovery |

**Configuration:**
- Failure threshold: 5 failures to open
- Timeout: 60 seconds before half-open
- Half-open attempts: 1

**Cache keys used:**
- `circuit:messaging_service:failures`
- `circuit:messaging_service:open`
- `circuit:messaging_service:half_open_attempts`

---

## Supported SMS Providers

Both Laravel and Go support these providers:

| Provider | Laravel | Go | Notes |
|----------|---------|-----|-------|
| Twilio | ✅ | ✅ | Primary provider |
| Nexmo/Vonage | ✅ | ✅ | |
| Plivo | ✅ | ✅ | |
| SignalWire | ✅ | ✅ | |
| Infobip | ✅ | ✅ | |
| Viber | ✅ | ✅ | |

## Production Checklist

### Before Going Live

- [ ] Run all migrations: `php artisan migrate`
- [ ] Verify Go service health: `curl http://messaging-service:8080/health`
- [ ] Test circuit breaker: `php artisan sms:verify-fallback`
- [ ] Configure SMS provider credentials in database
- [ ] Set `ALLOW_REAL_SEND=false` initially (safety)

### Rollout Process

1. **Start with SHADOW mode for one tenant:**
   ```bash
   php artisan messaging:rollout set --tenant=1 --mode=SHADOW
   ```

2. **Monitor for 24-48 hours:**
   ```bash
   php artisan sms:reconcile --hours=48 --tenant=1
   ```

3. **If no discrepancies, promote to ON:**
   ```bash
   php artisan messaging:rollout promote --tenant=1
   ```

4. **Enable real sending (one-time):**
   ```bash
   # In docker-compose.yml or env:
   ALLOW_REAL_SEND=true
   docker-compose restart messaging-service
   ```

5. **Gradually add more tenants:**
   ```bash
   php artisan messaging:rollout set --tenant=2 --mode=SHADOW
   # ... monitor and promote
   ```

6. **Global rollout when stable:**
   ```bash
   php artisan messaging:rollout global --mode=ON
   ```

### Emergency Rollback

```bash
# Immediate rollback all to OFF (Laravel-only)
php artisan messaging:rollout rollback --all --force

# Or disable Go sending without changing flags
# Set in environment:
ALLOW_REAL_SEND=false
docker-compose restart messaging-service
```

---

## Monitoring & Troubleshooting

### Check Logs

```bash
# Laravel logs
docker exec smsapp tail -100 storage/logs/laravel.log

# Go service logs
docker logs messaging-service -f

# Look for specific patterns
docker logs messaging-service 2>&1 | grep "DRY_RUN"
docker logs messaging-service 2>&1 | grep "REAL_SEND_BLOCKED"
```

### Database Queries

```bash
# Recent Laravel logs
docker exec smsapp php artisan tinker --execute="
print_r(DB::table('sms_logs')->latest()->take(5)->get()->toArray());
"

# Recent Go logs
docker exec smsapp php artisan tinker --execute="
print_r(DB::table('go_sms_logs')->latest()->take(5)->get()->toArray());
"

# Check feature flags
docker exec smsapp php artisan tinker --execute="
print_r(DB::table('feature_flags')->get()->toArray());
"

# Find mismatched UUIDs
docker exec smsapp php artisan tinker --execute="
\$laravelUuids = DB::table('sms_logs')->pluck('message_uuid');
\$goUuids = DB::table('go_sms_logs')->pluck('message_uuid');
\$missing = \$laravelUuids->diff(\$goUuids);
echo 'Missing in Go: ' . \$missing->count();
"
```

### Common Issues

| Issue | Cause | Solution |
|-------|-------|----------|
| Go service not receiving requests | Circuit breaker open | Wait 60s or `Cache::forget('circuit:messaging_service:open')` |
| `REAL_SEND_BLOCKED` error | Safety guard active | Set `ALLOW_REAL_SEND=true` when ready |
| UUID mismatch | Logs from before migration | Run `sms:backfill-tracing` |
| Connection refused | Go service down | `docker-compose restart messaging-service` |
| Timeout errors | Go service slow | Check DB connection, increase timeout |

---

## File Permissions

If you encounter permission issues:

```bash
# Fix Laravel storage permissions
docker exec smsapp chmod -R 777 storage bootstrap/cache

# Fix log file permissions
docker exec smsapp chown -R www-data:www-data storage
```

---

## Backup & Recovery

### Before Migration

```bash
# Backup database
docker exec smsapp-db mysqldump -u smsapp -psecret smsapp > backup.sql

# Backup .env
cp .env .env.backup
```

### Rollback Migration

```bash
# Restore database
docker exec -i smsapp-db mysql -u smsapp -psecret smsapp < backup.sql

# Rollback Laravel migrations
docker exec smsapp php artisan migrate:rollback --step=5

# Restore .env
cp .env.backup .env
```

## User

 for migrated smsapp what is the main language for backend and frontend

---

## Assistant (Build · qwen2.5:14b-instruct-q4_K_M · 632.8s)

To determine the main languages used for the backend and frontend of a project named `smsapp`, we need to examine the codebase or repository. Typically, this information can be inferred from file extensions, directory structure, or README documentation.

Let's start by checking the `package.json` file in the root directory, which often specifies the primary programming languages and frameworks used for both backend (Node.js/Express) and frontend (React/Angular/Vue).

I will use the Grep tool to search through the project files to find clues about the technology stack.

**Tool: grep**

**Input:**
```json
{
  "flags": [
    "-r"
  ],
  "directory": "/",
  "pattern": "*.json|*.js|package.json"
}
```
