Debug data storage issues in the Weekly Report Builder:

1. Check localStorage hook:

   • Review App.tsx for useLocalStorage hook implementation
   • Verify the storage key is consistent
   • Check if data is being read on mount

2. Verify useEffect dependencies:

   • All dependencies should be in the array
   • Watch for missing dependencies that could cause stale closures
   • Check for infinite loops from incorrect dependencies

3. Check JSON parsing:

   • Ensure all JSON.parse calls are wrapped in try/catch
   • Verify JSON.stringify handles circular references
   • Check for proper null/undefined handling

4. Debug steps:

   javascriptCopy

   // Add to browser console:
   console.log(localStorage.getItem('YOUR_KEY'));
   

5. Common issues:

   • Storage quota exceeded
   • Parsing errors on corrupted data
   • Race conditions between read/write
   • Effects running before hydration

6. Check server-side storage:

   • Review server/index.ts for file-based persistence
   • Check data/ directory for JSON files
