Interpretation (2026-09-09)

v6 tested v4 §13's two genuinely open items — factor observations and a long-horizon Sharpe reward — holding everything else at v4 config A. Neither rescues the allocator: median uplift −0.053, p=0.495.

The informative pattern is window-1 unanimity: all 5 seeds gain +0.16..+0.20 in w1 and lose in w0/w2. Seed-consistency means the agent LEARNED a systematic tilt (not noise); its failure is overfitting to regime, not failure to learn. Learning capacity was never the problem — stationarity was. This answers the "did we look clearly" challenge directly: across v3 (free/churny), v4 (constrained/EW), v5 (loose/worse), v6 (smart/regime-specific), each better-posed generation confirms the same null from a new angle, consistent with DeMiguel-Garlappi-Uppal 1/N: with diversified sleeves and ~300 lifetime allocation decisions, there is no robust learnable tilt. A v7 would need a different problem (execution is infeasible here), not a better setup of this one.
