# Dify Specialist Consultation - Care Book Block Ultimate
|
||||
|
||||
**Date**: 2025-09-12 22:40
|
||||
**Status**: SIMULADA (conectividade issues)
|
||||
**Consultation Type**: Multi-Specialist Critical Analysis
|
||||
**Plan Phase**: Implementation Plan Validation
|
||||
|
||||
---
|
||||
|
||||
## 🎯 CONSULTATION REQUEST
|
||||
|
||||
**Context**: WordPress Plugin for KiviCare Appointment Control
|
||||
**Stack**: PHP 8.1+, WordPress 6.8+, MySQL 8.0+, KiviCare 3.6.8+
|
||||
**Architecture**: CSS-first + hook-based integration
|
||||
**Request**: Critical validation of implementation plan
|
||||
|
||||
## 📋 CRITICAL QUESTIONS IDENTIFIED
|
||||
|
||||
### 1. **Hook Dependencies Risk** 🔴
|
||||
**Question**: KiviCare pode alterar hooks/filters sem aviso?
|
||||
**Risk Level**: HIGH
|
||||
**Analysis**:
|
||||
- KiviCare é plugin third-party - pode quebrar integração
|
||||
- Hooks não documentados podem ser removidos/alterados
|
||||
- Plugin updates podem quebrar funcionalidade
|
||||
|
||||
**🛡️ MITIGATION**:
|
||||
- Implementar fallback mechanisms
|
||||
- Version checking antes de usar hooks
|
||||
- Wrapper functions para isolamento
|
||||
- Monitoring para detectar breaking changes
|
||||
|
||||
### 2. **Performance CSS (FOUC Risk)** ⚠️
|
||||
**Question**: CSS injection pode causar FOUC (Flash of Unstyled Content)?
|
||||
**Risk Level**: MEDIUM
|
||||
**Analysis**:
|
||||
- CSS inline pode carregar após HTML rendering
|
||||
- Elementos podem ser visíveis antes de ocultação
|
||||
- Impacto na experiência do utilizador
|
||||
|
||||
**🛡️ MITIGATION**:
|
||||
```css
|
||||
/* Critical CSS inline no head */
|
||||
.kivicare-booking-form { visibility: hidden; }
|
||||
.kivicare-form-loaded { visibility: visible; }
|
||||
|
||||
/* Progressive enhancement approach */
|
||||
```
|
||||
|
||||
### 3. **Database Scaling** 📈
|
||||
**Question**: Como custom table escala com 10K+ médicos?
|
||||
**Risk Level**: MEDIUM
|
||||
**Analysis**:
|
||||
- Current design: O(n) queries
|
||||
- MySQL 8.0 pode otimizar mas needs proper indexing
|
||||
- Memory impact com milhares de registros
|
||||
|
||||
**🛡️ MITIGATION**:
|
||||
```sql
|
||||
-- Composite indexes otimizados
|
||||
INDEX idx_doctor_active (doctor_id, is_active) USING BTREE;
|
||||
INDEX idx_service_type (service_id, restriction_type) USING BTREE;
|
||||
|
||||
-- Partitioning por is_active para performance
|
||||
PARTITION BY LIST(is_active) (
|
||||
PARTITION active VALUES IN (1),
|
||||
PARTITION inactive VALUES IN (0)
|
||||
);
|
||||
```
|
||||
|
||||
### 4. **Cache Invalidation Strategy** 🔄
|
||||
**Question**: Estratégia para invalidação cache distribuído?
|
||||
**Risk Level**: HIGH
|
||||
**Analysis**:
|
||||
- WordPress Transients = single-server cache
|
||||
- Multi-server environments precisam cache distribuído
|
||||
- Cache inconsistency pode causar bugs
|
||||
|
||||
**🛡️ MITIGATION**:
|
||||
```php
|
||||
// Cache invalidation strategy
|
||||
interface CacheInvalidation {
|
||||
public function invalidateDoctor(int $doctorId): void;
|
||||
public function invalidateService(int $serviceId): void;
|
||||
public function invalidateAll(): void;
|
||||
}
|
||||
|
||||
// Support for Redis/Memcached
|
||||
class DistributedCacheInvalidation implements CacheInvalidation {
|
||||
// Implementation for multi-server environments
|
||||
}
|
||||
```
|
||||
|
||||
### 5. **Security - AJAX Endpoints** 🔒
|
||||
**Question**: AJAX endpoints expostos a ataques CSRF/XSS?
|
||||
**Risk Level**: CRITICAL
|
||||
**Analysis**:
|
||||
- WordPress nonces podem ser insufficientes
|
||||
- Input validation necessária
|
||||
- Output escaping obrigatório
|
||||
|
||||
**🛡️ MITIGATION**:
|
||||
```php
|
||||
// Enhanced security validation
|
||||
class SecurityValidator {
|
||||
public function validateAjaxRequest(): void {
|
||||
// 1. WordPress nonce
|
||||
if (!wp_verify_nonce($_POST['nonce'], 'care_booking_nonce')) {
|
||||
wp_die('Security check failed');
|
||||
}
|
||||
|
||||
// 2. Capability check
|
||||
if (!current_user_can('manage_care_restrictions')) {
|
||||
wp_die('Insufficient permissions');
|
||||
}
|
||||
|
||||
// 3. Rate limiting
|
||||
if (!$this->checkRateLimit()) {
|
||||
wp_die('Too many requests');
|
||||
}
|
||||
|
||||
// 4. Input validation
|
||||
$this->validateInputData($_POST);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 6. **Plugin Conflicts** ⚔️
|
||||
**Question**: Namespace collision com outros plugins WordPress?
|
||||
**Risk Level**: MEDIUM
|
||||
**Analysis**:
|
||||
- PSR-4 namespacing resolve maioria dos conflitos
|
||||
- Global functions podem colidir
|
||||
- CSS classes podem conflitar
|
||||
|
||||
**🛡️ MITIGATION**:
|
||||
```php
|
||||
// Namespace isolation
|
||||
namespace CareBook\Ultimate\{
|
||||
Core\,
|
||||
Admin\,
|
||||
Models\
|
||||
}
|
||||
|
||||
// Prefixed global functions
|
||||
function care_book_ultimate_init() {
|
||||
// Plugin initialization
|
||||
}
|
||||
|
||||
// CSS prefixing
|
||||
.care-book-ultimate-container { }
|
||||
.care-booking-restriction-toggle { }
|
||||
```
|
||||
|
||||
### 7. **PHP 8+ Migration Path** 🔄
|
||||
**Question**: Migration path para hosting providers antigos?
|
||||
**Risk Level**: HIGH
|
||||
**Analysis**:
|
||||
- Muitos hosting ainda em PHP 7.4/8.0
|
||||
- Breaking changes podem impedir adoption
|
||||
- Client environments podem não suportar
|
||||
|
||||
**🛡️ MITIGATION**:
|
||||
```php
|
||||
// Graceful degradation
|
||||
if (version_compare(PHP_VERSION, '8.1.0', '<')) {
|
||||
add_action('admin_notices', function() {
|
||||
echo '<div class="notice notice-error">
|
||||
<p>Care Book Ultimate requires PHP 8.1+. Current: ' . PHP_VERSION . '</p>
|
||||
</div>';
|
||||
});
|
||||
return; // Prevent plugin loading
|
||||
}
|
||||
|
||||
// Feature detection
|
||||
$hasReadonlyClasses = version_compare(PHP_VERSION, '8.1.0', '>=');
|
||||
```
|
||||
|
||||
### 8. **Testing Strategy** 🧪
|
||||
**Question**: Como testar integração sem modificar KiviCare?
|
||||
**Risk Level**: MEDIUM
|
||||
**Analysis**:
|
||||
- Integration tests needs KiviCare active
|
||||
- Mock objects para unit testing
|
||||
- E2E testing complexo
|
||||
|
||||
**🛡️ MITIGATION**:
|
||||
```php
|
||||
// KiviCare Mock for testing
|
||||
class MockKiviCareIntegration {
|
||||
public function simulateBookingForm(): array {
|
||||
return [
|
||||
'doctors' => $this->getMockDoctors(),
|
||||
'services' => $this->getMockServices()
|
||||
];
|
||||
}
|
||||
}
|
||||
|
||||
// Integration testing with actual KiviCare
|
||||
class KiviCareIntegrationTest extends WP_UnitTestCase {
|
||||
protected function setUp(): void {
|
||||
if (!is_plugin_active('kivicare/kivicare.php')) {
|
||||
$this->markTestSkipped('KiviCare not available');
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 9. **Rollback Strategy** ↩️
|
||||
**Question**: Como reverter plugin sem perder dados?
|
||||
**Risk Level**: MEDIUM
|
||||
**Analysis**:
|
||||
- Database changes podem ser irreversíveis
|
||||
- Custom table data loss risk
|
||||
- Configuration rollback needed
|
||||
|
||||
**🛡️ MITIGATION**:
|
||||
```php
|
||||
// Rollback mechanism
|
||||
class PluginRollback {
|
||||
public function createBackup(): void {
|
||||
// Backup custom table
|
||||
$this->backupRestrictionsTable();
|
||||
// Backup options
|
||||
$this->backupPluginOptions();
|
||||
}
|
||||
|
||||
public function rollback(): void {
|
||||
// Restore from backup
|
||||
$this->restoreDatabase();
|
||||
$this->restoreOptions();
|
||||
}
|
||||
}
|
||||
|
||||
// Version tracking for safe upgrades
|
||||
register_activation_hook(__FILE__, ['PluginRollback', 'createBackup']);
|
||||
```
|
||||
|
||||
### 10. **Production Monitoring** 📊
|
||||
**Question**: Como detectar falhas de integração em produção?
|
||||
**Risk Level**: HIGH
|
||||
**Analysis**:
|
||||
- Silent failures podem passar despercebidos
|
||||
- KiviCare updates podem quebrar integração
|
||||
- Performance degradation detection
|
||||
|
||||
**🛡️ MITIGATION**:
|
||||
```php
|
||||
// Health check system
|
||||
class HealthMonitor {
|
||||
public function checkKiviCareIntegration(): array {
|
||||
return [
|
||||
'hooks_available' => $this->checkRequiredHooks(),
|
||||
'database_accessible' => $this->checkDatabaseHealth(),
|
||||
'cache_working' => $this->checkCacheSystem(),
|
||||
'permissions_correct' => $this->checkPermissions()
|
||||
];
|
||||
}
|
||||
|
||||
// WordPress cron for regular monitoring
|
||||
public function scheduleHealthChecks(): void {
|
||||
wp_schedule_event(time(), 'hourly', 'care_booking_health_check');
|
||||
}
|
||||
}
|
||||
```
