list_documents()lookup_reference(reference="first-half")lookup_reference(reference="second-half")Reasoning
The task says "Retrieve contribution_rate from the supplied rulebook." But R8 says retrieval tasks ask for exactly one named value for its supplied payroll month. However, no payroll_month is supplied here. Hmm. The task says "Retrieve contribution_rate from the supplied rulebook." The rules say retrieval tasks must have a month covered by a reference row; malformed retrieval tasks are dataset errors. Let me look at documents first.
