๐Ÿ”บ A3 โ€” Higher-order / synergy

Top pick: O-information + permutation null (hoi (BSD-3) โ€” bias-centered shuffle null; naive |ฮฉ|โ‰ฅ0.5 flag dropped). Fills the gap: Synergy (higher-order) โ€” de-scoped to a cheap permutation-null watch โ€” which the production baseline (Pearson + Spearman + h_norm + Tier-2 MI-vs-target) cannot detect.
