Two deeper analyses, both pure from existing data (no new API cost):
- ConvictionEdgePct: return% of the biggest-bet third minus the smallest-bet
third of closed markets. Positive => sizing carries information (copy
size-weighted); negative => overbets losers (red flag). CalculateMarketWinRates
now emits per-market (invested, returnPct) pairs consumed by
StrategyMetricsCalculator.ComputeConvictionEdge.
- CategoryConcentration: Herfindahl index of category volume shares
(specialist vs generalist), from the category-performance dict.
