## AI Providers Configuration

```env
# Default provider
AI_DEFAULT_PROVIDER=openrouter

# OpenRouter
OPENROUTER_API_KEY=sk-or-v1-...
OPENROUTER_MODEL=google/gemini-2.0-flash-exp:free

# OpenAI
# AI_DEFAULT_PROVIDER=openai
# OPENAI_API_KEY=sk-...
# OPENAI_MODEL=gpt-4o-mini

# StepFun
# AI_DEFAULT_PROVIDER=stepfun
# STEPFUN_API_KEY=...
# STEPFUN_MODEL=step-3.5-flash

# llama.cpp (local)
# AI_DEFAULT_PROVIDER=llamacpp
# LLAMACPP_BASE_URL=http://localhost:8080/v1/

# QwenCloud
# AI_DEFAULT_PROVIDER=qwen
# QWEN_API_KEY=...
# QWEN_MODEL=qwen-max
```

## Console Commands

```bash
# Send scheduled insights to users
php artisan insights:send

# Send insights for a specific user
php artisan insights:send --user=1

# Send insights for a specific subject
php artisan insights:send --subject=1
```

## Scheduler (Cron Job)

The insight scheduling system requires a cron job on the Linux host to function. The Laravel Scheduler needs only **1 crontab entry**.

### Cron Configuration

For Docker deployment, add this line to the host crontab:

```bash
* * * * * docker exec -u www-data dockerank2 php /var/www/html/artisan schedule:run >> /var/log/annunk-cron.log 2>&1
```

### Scheduled Tasks

| Command | Frequency | Description |
|---------|-----------|-------------|
| `insights:send` | Every 15 minutes | Sends scheduled insights to users |
| `insights:send` | Daily 00:00 | Additional verification |

### How it works:
1. Cron executes `php artisan schedule:run` every minute
2. Laravel Scheduler checks for pending tasks
3. `insights:send` command processes schedules using each user's timezone
4. Generates insights via AI and sends to Dashboard and/or Telegram as configured
5. Logs in `storage/logs/insights-scheduler.log`

## Multilingual Support

Three languages supported:
- **pt_BR**: Português do Brasil (default)
- **en**: English
- **es**: Español

Users switch languages via the navbar dropdown (Alpine.js). Translation files in `lang/{locale}/`.

## Security

- **Math Captcha**: All public forms (login, register) require solving a math addition
- **CSRF Protection**: All forms include CSRF tokens
- **User Approval**: New registrations require SuperAdmin approval
- **Role-Based Access**: Spatie Laravel Permission controls access to routes
- **Input Validation**: All user input is validated and sanitized
- **Content Filtering**: Chat messages are validated against prohibited content (profanity, pornography, politics, religion, prejudice)
- **AI Model Hidden**: Admin users cannot see which AI model is being used
- **Password Security**: Passwords are hashed using bcrypt
