 ### 6. Authentication & Authorization
 - [ ] Emojis require valid JWT authentication (like other claims)

-**Content Validation:**
-- [ ] Text length limit (e.g., 280 characters like Twitter)
-- [ ] Unicode emoji validation (optional - could allow any text)
-- [ ] Prevent empty or whitespace-only submissions
-- [ ] Sanitize text input for security

-**Business Rules:**
-- [ ] One emoji submission per user per item (or allow multiple?)
-- [ ] Prevent self-emoji on own GiveActions (optional business rule)
-- [ ] Consider moderation capabilities for inappropriate content

 - Follows the established database and API patterns
 - Maintains consistency with existing visibility and authentication rules
 - Supports the distributed/P2P vision by storing emojis as signed claims
-
-The emoji feature will integrate seamlessly with the existing GiveAction display system, showing emoji counts alongside other give information and providing a separate endpoint for detailed emoji retrieval when users want to see who reacted and with what emojis.
