Your Submission
This is a show-it-working challenge: fix the integration, run it against the Yuno sandbox, and hand in a short demo + evidence. Everything autosaves to this browser. When you're done, hit Submit — it goes straight to the review panel, you can't resend. Your manager will follow up with feedback.
