GPAW26.7.0 new-backend LCAO scissors, two real SCFs: plain and atomic-region scissors on twoH2. Four unchanged-density shifts on each. Raw occupations are copied and only detached arrays are weighted,avoiding installed default occupation getter mutating occ_n in place. Native source unchanged.
Scissors are supplied model shifts,not GW/quasiparticle predictions. Regional shifts follow contiguous atom counts;use symmetryoff if regions break atom permutations. No structural-force/total-energy/binding accuracy claim from this operator.
