• SupernodalLUFactorization returns Success with backward error far from machine precision on some SuiteSparse collection matrices

• ForwardDiff extension: a Symmetric or Hermitian matrix of Duals throws in nodual_value

• Default solver: reverse mode after the LU-to-QR fallback uses the failed LU, so ∂b is NaN or wrong

• Enzyme: a constant sparse A gets a shadow with no stored entries, so reverse mode throws a BoundsError

• Adjoint solves through QRFactorization throw for a sparse A or a wide dense A, so reverse mode fails

• ForwardDiff extension: a wide A drops the null-space term, so ∂A is wrong

• ForwardDiff extension: in-place updates to cache.A leave the primal matrix and partials stale, so isfresh solves the previous system
