|
|
## 🔧 Technical Debt & Considerations
|
|
|
|
### Current Technical Debt
|
|
1. SMS/WhatsApp integration stubs need real implementation
|
|
2. UI components need development
|
|
3. State machine could be more explicit
|
|
4. More comprehensive testing needed
|
|
|
|
### Performance Considerations
|
|
- ID generation is database-dependent (consider caching)
|
|
- Reminder scheduling scales with appointment volume
|
|
- Financial checks query multiple tables (consider optimization)
|
|
|
|
### Security Considerations
|
|
- ✅ Consent signatures tracked with IP and user agent
|
|
- ✅ Financial data protected
|
|
- ✅ Audit logging implemented
|
|
- 🔄 Need to add rate limiting for APIs
|
|
- 🔄 Need to implement confirmation token security
|
|
|
