Summary

Implements header-based session authentication to enable the worlddriven webapp proxy pattern while maintaining full backward compatibility with existing cookie-based authentication.

Changes

Database Layer

• Extended database.js: Added Session typedef and sessions collection getter
• Follows existing pattern for collection access
• Enables type-safe session queries

Session Authentication Middleware

• New file: src/middleware/sessionAuth.js
• Extracts and validates Authorization: SESSION <sessionId> headers
• Queries MongoDB sessions collection directly
• Validates session expiration
• Sets req.session.userId for compatibility with existing routes
• Falls back gracefully to cookie-based auth if no header present

API Endpoints

• GET /api/auth/status: Check authentication status and return user info
• POST /api/auth/logout: Destroy session

Middleware Integration

• Applied after express-session setup in src/index.js
• Automatically supports both authentication methods

Architecture

Webapp Proxy Pattern Flow

1. User authenticates via existing GitHub OAuth flow
2. Webapp proxy extracts sessionId from httpOnly cookie
3. Proxy sends Authorization: SESSION <sessionId> to core
4. Core middleware validates session from MongoDB
5. Existing routes work unchanged with req.session.userId

Backward Compatibility

• ✅ Current frontend with cookies continues to work
• ✅ New webapp proxy with headers works
• ✅ Both methods can be used simultaneously
• ✅ No breaking changes to existing code

Security

• Sessions remain in MongoDB with existing security
• httpOnly cookies prevent JavaScript access in webapp
• Session validation includes expiration checks
• No session data exposed in responses

Testing

• ✅ ESLint passes with no errors or warnings
• Ready for integration testing with webapp proxy
