Load for: which entity a US program attaches to (tax_unit vs spm_unit vs person), tax-unit role flags and filing status, post-OBBBA current-law values (2026 CTC, standard deduction, SALT cap), the parameter tree (gov.irs / gov.states.{xx} / gov.usda.snap / gov.ssa), state income-tax and credit coverage, and SNAP monthly/FPL semantics. Triggers: EITC, CTC, SNAP, TANF, SSI, income tax, state income tax, standard deduction, SALT cap, federal poverty level, spm_unit, tax_unit, filing status, is_tax_unit_dependent, household_net_income, in_poverty, state credit, CalEITC, ca_eitc, ny_eitc, OBBBA. NOT for: implementing new US variables/parameters (use policyengine-model-development); Medicaid/ACA/CHIP/Medicare (use policyengine-healthcare); the core calculate_household / Simulation / reform mechanics shared across countries (use the policyengine skill).
