Coarse, anonymous-safe screen of a household across SNAP and a simplified Medicaid income check. Returns a 'likely eligible' signal per program with a citation. This is NOT a determination and stores no data. Available to the screening scope. For a real determination, use check_program_eligibility.

Run the full deterministic SNAP financial eligibility test for a household. Returns the decision PLUS the rule trace and the policy citation behind every rule that fired, plus the ruleset version -- never a bare yes/no. Requires the caseworker scope. 'program' must be 'SNAP'.

List the documents a caseworker must verify to confirm SNAP eligibility for a household, derived from the facts the household presents (earned income implies pay stubs, shelter costs imply a lease, and so on). Requires the caseworker scope.

Return a plain, step-by-step trace of a prior determination by its id: which rules fired, what they saw, and the citation behind each. Requires the caseworker scope. Use the determination_id returned by check_program_eligibility.

Answer a SNAP policy question with citations to the eligibility manual. Delegates to the policy-manual-rag retrieval index. Currently a stub that returns an explicit placeholder rather than an invented answer. Available to the screening scope.
