This PR addresses the remaining ill-conditioned case in #196112 . Codex prepared the following description for review: The MPS Jacobi SVD skips rotations when the product of two column norms falls below float32 epsilon, even when the columns are strongly correlated. For the ill-conditioned input in #196112 this produces non-orthogonal U and inflated small singular values. Apply the relative correlation criterion to…
