…-circuit
- Add `takes_up_tanf_if_eligible` variable (bool, SPMUnit, default True)
- Wire all 39 implemented state TANF programs into tanf.py:
26 with standard naming ({st}_tanf) and 13 with program-specific
names (ak_atap, ct_tfa, fl_tca, ia_fip, md_tca, mi_fip, mn_mfip,
nj_wfnj, nm_works, ri_works, vt_reach_up, wi_works, wv_works)
- Apply takeup in TANF formula: value * takes_up
- Remove tanf_reported short-circuit that blocked reform microsimulations
- Update tests for new behavior
Companion to PolicyEngine/policyengine-us-data#536 which adds
state-level TANF takeup rates to microdata construction.
Closes PolicyEngine#7400

FL TCA's payment standard depends on housing_cost, which cycles back through rent → housing_assistance → hud_annual_income → tanf. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
FL TCA payment standard now uses pre_subsidy_rent instead of housing_cost, avoiding the cycle: tanf -> fl_tca -> housing_cost -> rent -> housing_assistance -> hud_annual_income -> tanf. This is more accurate: TANF agencies assess shelter obligation based on what applicants owe, not the net amount after housing subsidies from a separate agency.

All FL TCA tests now use pre_subsidy_rent instead of rent/housing_cost, matching the formula change in fl_tca_payment_standard. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Same pattern as FL TCA fix: use pre_subsidy_rent + other housing components instead of housing_cost to break the cycle tanf -> az_tanf -> housing_cost -> rent -> housing_assistance -> hud_annual_income -> tanf. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The baseline test used FL because it had no TANF implementation, but now that fl_tca is wired up, this household receives TANF. Set takes_up_tanf_if_eligible to false since this test is about ECPA, not TANF. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
MI household resources includes tanf. Now that mi_fip is wired up, this family receives TANF which increases their household resources and changes the home heating credit. Suppress TANF since this test is about the home heating credit, not TANF. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…rams Changed 22 state TANF childcare deduction formulas to use spm_unit_pre_subsidy_childcare_expenses instead of childcare_expenses, breaking the cycle: TANF → childcare_expenses → childcare subsidies → SNAP → tanf. Also fixed VT Reach Up housing allowance to use pre_subsidy_rent instead of housing_cost, breaking the same type of cycle as FL TCA and AZ TANF. States affected (childcare): AL, AK, AZ, DC, DE, GA, HI, IL, KY, MD, ME, MN, MO, NH, NM, OK, RI, TN, TX, VA, VT, WV States affected (housing): VT Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

The childcare "cycle" (TANF → childcare_expenses → childcare subsidies → SNAP → TANF) was an implementation artifact, not a real policy interaction. Root cause: CO CCAP's co_ccap_countable_income used SNAP income variables as a placeholder (with a TODO comment), creating a false dependency chain. California, Nebraska, and Massachusetts childcare subsidies never included SNAP in their income definitions. Changes: - Replace CO CCAP placeholder with actual income sources per 8 CCR 1403-1 - Switch 24 state TANF programs from spm_unit_pre_subsidy_childcare_expenses to childcare_expenses (the accurate post-subsidy amount) - Switch SNAP dependent care deduction from pre_subsidy_childcare_expenses to childcare_expenses (workaround no longer needed) - Update 65+ test files to match Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
co_ccap_countable_incomeused SNAP income variables as a placeholder (with a TODO), creating a false dependency chain through the static graph. Replaced with actual income sources per 8 CCR 1403-1 Section 7.105.spm_unit_pre_subsidy_childcare_expensesworkaround tochildcare_expenses(the accurate post-subsidy amount). States: AK, AL, AZ, DC, DE, GA, HI, IL, KS, KY, MD, ME, MN, MO, MT, NH, NM, OK, RI, TN, TX, VA, VT, WV.pre_subsidy_childcare_expensestochildcare_expenses— the workaround is no longer needed since no childcare subsidy program (CA, CO, NE, MA) depends on SNAP income.Why the cycle was false
The suspected cycle ran:
tanf→ state TANF → childcare deduction →childcare_expenses→ childcare subsidies → SNAP →tanf. An audit found:snap_earned_income+snap_unearned_incomeas a placeholderWith CO CCAP fixed to use the correct statutory income sources, the cycle no longer exists.
