# Challenge System Enhancement Summary

This implementation addresses all requirements from the problem statement:

## ✅ 1. Challenge Acceptance/Joining Flow
- **Added required `creator_game_username` field** - Challengers must provide their in-game username
- **Added optional `group_link` and `group_id` fields** - For lobby/room join information
- **Enhanced challenge creation form** with dedicated "Game Join Information" section
- **Updated challenge view** to prominently display all join information to invited users

## ✅ 2. Post-Game Winner/Loser Confirmation
- **Replaced generic "Agree with Result"** with specific "I Won" and "I Lost" buttons
- **Automatic payout** when results match (one clicks Win, other clicks Lose)
- **Individual result tracking** with `creator_claimed_result` and `accepter_claimed_result` fields

## ✅ 3. Dispute/Conflict Resolution
- **Automatic dispute creation** when both players claim victory
- **Evidence upload requirement** for disputes where both claim to have won
- **Admin notification system** when both parties provide evidence
- **Enhanced admin interface** for reviewing evidence and making decisions

## ✅ 4. General UI/UX Improvements
- **Prominent join information display** in challenge view
- **Clear status indicators** for result claims and evidence uploads
- **Progressive disclosure** of evidence upload interface when needed
- **Comprehensive error handling** and user feedback
