🚨 Fixed Major Data Leakage Issues:
- Replaced hardcoded user_id = 1 with proper JWT authentication
- Fixed collections API to filter by authenticated user
- Fixed card ownership to use user_cards table (not global cards table)
- Fixed decks API to return only user-owned decks
- Fixed card collections/decks APIs to respect user permissions
- Fixed favorites API to use user_favorites table
🛡️ Authentication & Authorization:
- All endpoints now require valid JWT tokens
- Proper user isolation across all data operations
- Collection permissions properly enforced
- User-specific data queries implemented
🔧 Database Schema Fixes:
- Card ownership now uses user_cards table
- Favorites use user_favorites table
- Decks filtered by user_id
- Collections respect ownership and permissions
⚠️ Development Note:
- Added warning for fallback authentication in dev mode
- Should be removed in production deployment
✅ Data Privacy Secured:
- Users can only see their own collections, decks, and owned cards
- Public collections visible to all (as intended)
- Shared collections respect permission levels
- No cross-user data leakage
🎯 Cleaner Permission System:
- Collections are private/invite-only by default
- Public toggle only controls community visibility (not edit permissions)
- Simplified to: Creator + Invited Collaborators can edit, everyone else view-only
- Only creator can delete collections
📝 UI/UX Enhancements:
- Changed 'Invite User' to 'Invite Collaborator' with clearer messaging
- Replaced visibility dropdown with clean public/private toggle
- Updated role descriptions: 'Collaborator' (editor) and 'Viewer'
- Default invitation role is now 'editor' (collaborator)
- Added explanatory text about collaboration purpose
🔐 Permission Logic Updates:
- Public collections: visible in community but invite-only editing
- Private collections: hidden from community, invite-only editing
- Removed complex visibility states (invite-only/private distinction)
- Updated permission middleware for simplified model
📧 Email Template Updates:
- Clearer role descriptions in invitation emails
- Focus on collaboration and card management permissions
- Removed owner role from invitation options
🗄️ Database Schema Updates:
- Updated APIs to use is_public boolean instead of visibility enum
- Maintained backward compatibility with existing data
- Simplified permission checking logic
The system now has a much cleaner UX: collections are collaborative workspaces that can optionally be made visible to the community! 🚀
