pytc.test.test_fixed_pivots¶

Unit tests for isdf_decompose fixed_pivots override path (pytc/df.py).

Covers the still-live fixed_pivots kwarg: native pivots fed back as fixed_pivots must reproduce bit-identical phi_piv/grad_phi_piv columns and agree to double precision on xi_phi / xi_grad. CPU-only so CI runs these without a GPU.
