Blocking: several work-requirement formulas use Python or with PolicyEngine arrays instead of vectorized bitwise operators. For example, medicaid_work_requirement_eligible returns has_exemption or has_ce, has_medicaid_work_requirement_ce returns enrolled_half_time or passed_hours or passed_income, and has_medicaid_work_requirement_exemption chains the exemption flags with or. This raises ValueError: The truth value of an array with more than one element is ambiguous in multi-person simulations. Repro on this branch with two people in 2027-03: has_medicaid_work_requirement_ce, medicaid_work_requirement_eligible, and yearly is_medicaid_eligible all raise that error. Please replace these with parenthesized vectorized expressions using |.
