 4. Confidence: Assign a confidence score (0-100) based on how clearly the data points to the decision.
 
+# Confidence Scoring Guide (CRITICAL)
+Assign the 'confidence' score based on these rules:
+- 80-100: When Financials are strong AND News Context clearly supports the trend.
+- 50-79: When Financials are stable but News is neutral or missing.
+- 10-49: When Financials and News contradict each other.
+- 1-9: Reserved ONLY for extreme data corruption. 
+- NEVER output 0 unless the data is completely unreadable. Even a weak guess should be at least 10.
