- Monolithic Component: 748-line
chat.tsx
file with mixed responsibilities - Complex Message Types: Overly complicated type system with multiple overlapping interfaces
- Performance Issues: Using FlatList instead of LegendList
- Poor Scalability: Hard to add new chat types (Face Scan, Smart Documents, etc.)
- Type Safety Issues: Inconsistent message handling and retry logic
- Maintenance Nightmare: Business logic mixed with UI components
