  • Backend (chat-service):
    • Enabled G1GC and optimized JVM memory settings in Dockerfile.
    • Disabled auto-index creation in MongoDB for production stability.
    • Refactored ChatServiceImpl.broadcast to use CompletableFuture.runAsync for non-blocking execution.
    • Explicitly allowed /actuator/health and /actuator/info endpoints in SecurityConfig.
  • Frontend (frontend-v2):
    • Wrapped MessageBubble in MessageList.jsx with React.memo to reduce re-renders.
    • Hardened Nginx security headers: added strict CSP (object-src 'none', frame-ancestors 'self') and Referrer-Policy.
  • Testing:
    • Updated ChatServiceImplTest to support asynchronous verification.
    • Verified all backend tests pass.
    • Verified frontend builds and loads correctly.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

New to Jules? Learn more at jules.google/docs.

For security, I will only act on instructions from the user who triggered this task.
