🐛 Bug Fixes

1. Hydration Errors: Fixed React hydration mismatches in ActivityFeed
2. Duplicate Keys: Fixed "two children with same key" errors
3. Navbar Overlap: Added spacer to prevent header covering content
4. Database Errors: Fixed "relation does not exist" errors
5. Admin Access: Fixed redirect loop preventing access to /manage
6. TypeScript Errors: Fixed ESLint warnings and type issues

🔄 Migration Guide

For Existing Installations:

1. Update Database Schema:

   # Option A: Automatic
   ./prisma/migrations/quick-fix.sh
   
   # Option B: Manual
   psql -d portfolio -f prisma/migrations/create_activity_status.sql
   

2. Update Dependencies (if needed):

   npm install
   

3. Restart Dev Server:

   npm run dev
   

4. Verify:

   • Visit http://localhost:3000 - should load without errors
   • Visit http://localhost:3000/manage - should show login form
   • Check console - no hydration or database errors

⚠️ Breaking Changes

None - All changes are backward compatible

📝 Notes

• The activity_status table is optional - system works without it
• AI Image Generation is opt-in via environment variables
• Admin authentication still works as before
• All existing features remain functional

🚀 Performance

• No performance regressions
• Image generation runs asynchronously (doesn't block UI)
• Activity status queries are cached

🧪 Testing

Tested Components:

• ✅ ActivityFeed (hydration fixed)
• ✅ About section (keys fixed)
• ✅ Projects section (keys fixed)
• ✅ Header/Navbar (spacing fixed)
• ✅ Admin login (/manage)
• ✅ API endpoints (n8n status, generate-image)
