# Photo Management and Game Features
## Summary
This PR adds comprehensive photo management features, duplicate detection, attempt limits, penalty system improvements, and admin photo deletion capabilities to the MirrorMatch application.
## Features Added
### 1. Duplicate Photo Detection
- **File-based duplicates**: Calculates SHA256 hash of uploaded files to detect duplicate content
- **URL-based duplicates**: Checks for duplicate photo URLs
- Prevents users from uploading the same photo multiple times
- Returns HTTP 409 (Conflict) with clear error messages
### 2. Maximum Attempts Per Photo
- Uploaders can set a maximum number of guesses allowed per user for each photo
- Default: unlimited (null or 0)
- UI displays remaining attempts counter
- API enforces attempt limits before allowing guesses
- Shows warning message when max attempts reached
### 3. Penalty System Improvements
- **Simplified UI**: Removed checkbox - penalty automatically enabled when penalty points > 0
- **Score protection**: Scores cannot go below 0, even with large penalties
- If penalty would result in negative score, only deducts available points and sets to 0
### 4. Admin Photo Deletion
- Admins can delete photos from:
- Photos list page (hover to reveal delete icon)
- Individual photo detail page (delete button in header)
- Deletes associated guesses automatically
- Deletes local uploaded files from filesystem
- Confirmation dialog before deletion
- Proper error handling and user feedback
### 5. Navigation Improvements
- Logout button always visible in side menu (hamburger menu)
- Improved side menu layout with fixed footer for logout button
- Better mobile responsiveness
### 6. Self-Guess Prevention
- Users cannot guess on their own uploaded photos
- Shows informative message with answer for photo owners
## Technical Changes
### Database Schema
- Added `fileHash` field (String?) to Photo model for duplicate detection
- Added `maxAttempts` field (Int?) to Photo model for attempt limits
- Added indexes on `url` and `fileHash` for performance
### API Routes
- `POST /api/photos/upload-multiple`: Enhanced with duplicate checking and maxAttempts
- `POST /api/photos/[photoId]/guess`: Added maxAttempts enforcement and score floor protection
- `DELETE /api/photos/[photoId]`: New route for admin photo deletion
### Components
- `DeletePhotoButton`: New reusable component for photo deletion
- Updated upload form to remove penalty checkbox
- Enhanced photo display pages with attempt counters and admin controls
## Database Migrations
- Run `npm run db:push` to apply schema changes
- Run `npm run db:generate` to regenerate Prisma client
## Testing
- Test duplicate detection with same file and different filenames
- Test duplicate detection with same URL
- Test max attempts enforcement
- Test penalty system with various point values
- Test score floor (cannot go below 0)
- Test admin photo deletion
- Test self-guess prevention
## Breaking Changes
None - all changes are backward compatible. Existing photos will have `null` for `maxAttempts` (unlimited) and `fileHash` (for URL uploads).
