- Support multi-pass residual decomposition (residual_decompose) with arbitrary n_passes. - Support multi-pass matrix multiplication modes: 1-pass, 2-pass (lhs_high_precision, rhs_high_precision), 3-pass (triangular), and 4-pass (full_cross) for mxfp8_16. - Support multipass_mode in DotGeneralQtConfig for forward and backward passes. - Add unit tests in multipass_test verifying algebraic component equivalence, SNR hierarchy across distributions, gradient accuracy, and normal distribution benchmarks (1, 2, 3, 4 passes).
