Code Duplication Status

High Duplication (Ready to Consolidate)

• 8 data tables → 1 DataTable component
• 10+ forms → 1 FormBuilder component
• 2 communication views → 1 UnifiedCommunication wrapper
• 4 analytics → 1 AnalyticsPanel component
• 5+ navigation files → 1 UnifiedNavMenu + config
• 60+ API fetch patterns → 1 useApi() hook

Current Baseline:

• 55 view/page components
• 3,000+ lines of table code (8 files)
• 4,000+ lines of form code (10+ files)
• 2,000+ lines of navigation code (5+ files)

After Consolidation:

• 12 unified modules
• 300 lines of table code (90% reduction)
• 400 lines of form code (90% reduction)
• 300 lines of navigation code (85% reduction)

Projected Savings: ~9,000 lines (50% of components)

• Test compliance gates (Module L)
• Load test database with production volume
• Security audit of auth flow

Day 3-4: Integration Testing

• Test all 25+ APIs
• Test data export/import (GDPR)
• Test signage, exam mode, notifications
• Test memory under sustained load

Day 5: Performance Tuning
