nx_nofloat_muon_ns_gate.nx -- gate for integer Newton-Schulz orthogonalization (Muon core). HONEST claim (Muon NS = APPROXIMATE orthogonalization, SVs -> ~1, not exactly 1): T1 a non-orthogonal matrix is orthogonalized -- X X^T -> I error drops hard (>5x) after NS T2 MONOTONE: more iterations reduce the error (err@5 < err@1) -- the iteration converges, not diverges T3 the result's X X^T diagonal lands near 1.0 (each in [0.6,1.4]*Q16) -- Muon-style approx-orthogonal T4 DETERMINISTIC: two runs bit-identical -- the NOVEL EXCEED (float NS is order-dependent, ours is not) license_tier: ORIGINAL No hw writes (Rule 26). expect_exit: 0
