 LLM assigns a final_score (0-100) and confidence (1-10) to each candidate.
 Score and confidence are correlated but not identical — a speculative setup
 can score 80 with confidence 6. The ranker uses final_score as primary sort key.
-No evidence yet on whether confidence or score is a better predictor of outcomes.

+P&L data provides first evidence on score vs. outcome relationship: overall 30d
+win rate is only 33.8% despite most recommendations having final_score >= 65.
+This suggests the LLM is systematically overconfident — scores in the 65-85 range
+do not reliably predict positive outcomes. Strategy identity (which scanner sourced
+the candidate) is a stronger predictor than score within that strategy.

 - [ ] Does score threshold (e.g. only surface candidates >70) improve hit rate?

+- MEDIUM: downgrade, miss, lawsuit, investigation, recall, warning
