I think this summary states that two credits are combined into one -> we will need variable adjustments as well I believe

[PavelMakarchuk]

We currently have 2 vairbales: co_cdcc.py and co_low_income_cdcc.py

After 2026 this should be just the co_cdcc so we will set the other variable to 0 starting in 2026 (through an in_effect parameter)
