How judge scoring works

Each judge evaluates responses independently using criteria like correctness, clarity, and efficiency. The ensemble aggregates their scores with visible rationales and agreement metrics.

To fix the authentication bug, check if the JWT token expiration is properly validated in the middleware. Add a try-catch block around the token verification and ensure the refresh token logic handles edge cases when the access token expires during an active session.
