 ### Fixed
 
+- We fixed Tiptap duplicate extension warnings for `link`, `textStyle`, `underline`, and `textDirection` by properly configuring StarterKit, removing redundant extension registrations in TextColorClass, memoizing the extensions array to prevent re-registration on component re-renders, and disabling the core TextDirection extension that conflicts with our custom implementation.
+
+- We fixed an issue where empty editor content was saving as `<p></p>` instead of an empty string, which incorrectly passed required field validation. Empty content now correctly saves as `""`, ensuring proper validation behavior. Note: This is a breaking change for forms that were relying on the incorrect behavior - required RichText fields will now correctly reject empty content.

 - We fixed an issue where the editor pasting back the whole sentence instead of the single copied word

+# Normalize Empty Content
+
+**Status:** Proposed  
+**Type:** Bug Fix  
+**Impact:** Breaking (Validation behavior)  
+**Effort:** ~3.5 hours
+
+## Quick Summary
+
+Fix the rich text editor to save empty content as `""` instead of `<p></p>`, ensuring correct validation and consistent data representation.
+
+## Problem
+
+When users delete all content, the editor currently saves `<p></p>` to the database. This breaks:
+
+- Required field validation (incorrectly passes)
+- Empty checks (`if (value)` returns true)
+- Data consistency (semantically empty ≠ empty string)
+
+## Solution
+
+Use Tiptap's `editor.isEmpty` property to return `""` when content is empty, and normalize comparison logic to treat `""` and `<p></p>` as equivalent.
+
+## Files
+
+- [`proposal.md`](./proposal.md) - Problem statement, scope, and impact
+- [`design.md`](./design.md) - Technical design, decisions, and architecture
+- [`tasks.md`](./tasks.md) - Implementation checklist and effort estimate
+
+## Key Decisions
+
+1. **Trust Tiptap's isEmpty** - Use built-in check, no custom logic
+2. **Normalize at persistence** - Convert to `""` when saving, not loading
+3. **Lazy migration** - Existing `<p></p>` records normalize on next edit
+4. **No version bump** - This Tiptap version is unreleased
+
+## Changes Required
+
+### Editor.tsx (line 237-240)
+
+```typescript
+// Before:
+const html = editor.getHTML();
+
+// After:
+const html = editor.isEmpty ? "" : editor.getHTML();
+```
+
+### EditorWrapper.tsx (line 48-60)
+
+```typescript
+// Add normalization in comparison:
+const normalizeEmpty = (val?: string) => (!val || val === "<p></p>" ? "" : val);
+
+const current = normalizeEmpty(stringAttribute.value);
+const incoming = normalizeEmpty(html);
+if (current !== incoming) {
+    stringAttribute.setValue(incoming);
+}
+```
+
+## Testing
+
+- ✓ Unit tests for empty content behavior
+- ✓ E2E test for persistence
+- ✓ Manual validation testing
+
+## Breaking Change
+
+**Required field validation will now correctly reject empty content.**
+
+Previously: `<p></p>` passed validation ❌  
+After fix: `""` fails validation ✓
+
+This is desired behavior (bug fix), but may affect existing forms.
+
+## Next Steps
+
+1. Review proposal and design
+2. Approve or request changes
+3. Implement following tasks.md
+4. Test thoroughly
+5. Update CHANGELOG
+6. Merge to main branch
