## Technical Architecture Status

### Phase 1 Foundation (feature/native-event-system)
- **HVAC_Event_Form_Builder**: 734 lines, native WordPress event forms
- **HVAC_Event_Manager**: Unified event management system
- **Performance Optimizations**: Transient caching, 211+ slow query fixes
- **Security Integration**: Native WordPress patterns, HVAC_Security framework

### Phase 2A Advanced Features (feature/phase-2-event-templates)
- **HVAC_Event_Template_Manager**: 876 lines, template CRUD operations
- **HVAC_Bulk_Event_Manager**: Bulk operations with background processing
- **Modern PHP 8+ Patterns**: Strict typing, comprehensive validation
- **Enhanced UX**: Template system, bulk operations interface

### Integration Requirements
- Merge both branches preserving all functionality
- Create HVAC_Event_System_Manager as unified entry point
- Maintain tribe_events post type for TEC Core compatibility
- Ensure seamless TEC ecosystem integration

## Key Issues & Solutions Status

### 1. TEC Community Events Failures ⚠️ CRITICAL
- **Issue**: "Security check failed" 500 errors, AJAX infinite loading
- **Root Cause**: TEC Community Events extension unreliability
- **Solution**: Replace extension forms with HVAC system, keep TEC Core
- **Status**: Solution designed, implementation planned

### 2. Performance Bottlenecks ⚠️ HIGH
- **Issue**: 211+ slow queries, "Error loading trainers table"
- **Root Cause**: Unoptimized database queries in trainer statistics
- **Solution**: Transient caching, query optimization, AJAX improvements
- **Status**: Optimization patterns identified, implementation planned

### 3. Frontend Integration Gap 🔧 MEDIUM
- **Issue**: Backend infrastructure exists but no frontend integration
- **Impact**: Users see TEC Community Events interface, can't access HVAC features
- **Solution**: Refactor pages to use HVAC backend (Week 2 of plan)
- **Status**: Page inventory required, refactoring strategy defined
