Lorentz-Gram-preserving hyperbolic attention

Replace an unconstrained nonlinearity on hyperbolic pairwise similarities with a function from the paper's exact Lorentz–Gram preserver family. The transformed similarity matrix remains realizable as Lorentz inner products of future-directed unit timelike vectors, allowing a network to sharpen or smooth hyperbolic neighborhoods without introducing geometrically impossible pairwise relations.

Orthogonal transitivity projection for pairwise logits

Given arbitrary pairwise preference logits, project their skew-symmetric part onto the additive-consistent subspace before converting logits into probabilities or rankings. This removes cyclic inconsistency using the Frobenius-nearest consistent matrix, guaranteeing transitive pairwise predictions while preserving the closest possible signal under squared error.
