Backtest segment is LEAN engine daily-marked. Parameters frozen as of Oct 2026 — future changes evaluated on forward data only. Paper segment is forward ledger accounting, not real fills. Note: the momentum leg shares Momentum I's universe and picks (weekly return corr ~0.89) — holding both is a leverage choice, not diversification. Trend-gate and vol-target variants tested worse than baseline in the LEAN matrix; dyn1 defensive sleeve pending full-window review.
