+/**
+ * KA-CHOW Auto-Patch
+ * Issue: Service evaluator is in critical health (score: 45)
+ * Service: evaluator
+ *
+ * The code was updated to include a retry mechanism with exponential backoff. This ensures that if the service evaluation fails due to transient issues, it will retry up to three times with increasing delays between attempts. Additionally, structured error logging is added to capture exceptions with context. This approach prevents the service from crashing and returns a default health score of 0 if all retries fail.
