Factor Snapshot Now

Trigger an immediate factor snapshot — copies the full screener_cache feature set (Piotroski, accruals, Beneish, AI displacement, momentum sub-scores, etc.) into factor_history. Companion to /snapshot-now.

Run daily so the multifactor backtest gets richer feature history than score_history's four sub-scores. After 30-60 days the multifactor probability engine can be backtested on its full feature surface.
