## Blockers & Risks

### Current Blockers (NONE - ready to proceed)
- ✅ All technical blockers resolved
- ✅ Architecture is sound
- ✅ Database is set up
- ✅ API framework is working

### Potential Risks
- **API Rate Limits**: Each provider has rate limits; implement caching + request queue
- **Provider Outages**: Use fallback providers; implement circuit breaker pattern
- **Data Privacy**: Ensure compliance with GDPR/privacy laws before collecting user data
- **Scaling**: May need Redis caching if traffic grows significantly

### Mitigation
- ✅ Fallback provider already in architecture
- ✅ Caching layer designed (Redis ready)
- ✅ Encryption for sensitive data
- ✅ Audit trail for compliance

## Notes for Next Developer

### Key Files to Review
1. `app/Services/ProviderRegistry.php` – Heart of the system
2. `app/Contracts/FlightProviderInterface.php` – Interface all flight adapters use
3. `config/skybird.php` – Feature configuration source of truth
4. `routes/web.php` – All API routes

### Commands to Remember
```bash
# Start dev server
php artisan serve --host=0.0.0.0 --port=8000

# Database inspector
php artisan tinker

# Run migrations
php artisan migrate:fresh --seed

# Clear all caches
php artisan cache:clear && php artisan config:clear

# View routes
php artisan route:list

# Generate new migration
php artisan make:migration table_name

# Watch logs
tail -f storage/logs/laravel.log
```

### System Flow
```
User Request
    ↓
EnforceFeatureScope Middleware (blocks hotels)
    ↓
Route Handler (validation)
    ↓
ProviderRegistry (loads provider)
    ↓
Provider Adapter (Amadeus/Mapbox/etc)
    ↓
External API Call
    ↓
DTO Normalization (FlightOffer/TaxiQuote)
    ↓
JSON Response
    ↓
SearchRequest Model (audit log)
```
