Backtest overfitting audit for factor research: probability of backtest overfitting (PBO), deflated Sharpe ratio, point-in-time data, purged walk-forward. Searches published factor libraries and reports what actually survived costs.

Most associations in this public semiconductor dataset are artifacts of time. 32 features clear BH-FDR with permutation p=0.0005, but only 2 survive a change of time period. Chronological split, DuckDB/SQL warehouse, SPC, cost-aware baseline, every transform fitted on train only.

Pre-registered falsification of the commodity carry premium (XS + TS) on 18 CME futures, 2010–2026 — design frozen before data; 0/2 arms promoted; four exchange-data identity traps documented along the way.
