🎓 Key Learning Points

Root Cause Analysis

The issue demonstrated an important architectural pattern:

• Asymmetry between create (uses full struct) and update (uses limited struct)
• Silent data loss - JSON unmarshaling silently drops unknown fields
• Importance of consistency - All configuration types should be updatable

Solution Pattern

The fix followed an established pattern in the codebase:

• Used same approach as FAQConfig
• Maintained consistency across configuration types
• Applied to all three system layers (types, service, frontend)

Testing Approach

Four-layer testing strategy:

1. Unit test - Service logic
2. Integration test - API handler
3. API test - HTTP request/response
4. Database test - Persistence verification
