What's changed?

The integration test 23_OF_LPS failed on AVX 512 enabled compute nodes due to minor floating point variations between instruction sets. We resolved this by tightening the convergence criteria, increasing scf thr from 2e-6 to 2e-10, which eliminates hardware dependent numerical differences. The relevant reference outputs have been updated accordingly.
