def ufv_frame_orthogonality_residual(data):  # UT3Frame .data -> max orthogonality deviation, per stack element

Max deviation of the four masked frame supercores from orthonormality, per stack element (shape stack_shape). Each masked supercore slice IS a hypothetical ragged core (mask the padding to zero); require its Gram == diag(outgoing_mask) – the masked-Gram pattern, over the four senses (up U, down/outer O, left L, right R), with the correct outgoing mask per sense (left core i -> frame_left_mask[i+1]). The uniform analog of fv_operations.fv_frame_orthogonality_residual(); the per-element oracle is the ragged one via to_t3frame. The boundary left/right cores are remainders and are not checked (so left checks cores 0..d-2, right checks 1..d-1).
