list_documents()lookup_reference(reference="first-half")lookup_reference(reference="second-half")
Reasoning
The task is a retrieval task for deduction_cap. But we need the payroll month — retrieval tasks must have a month covered by a reference row. Let me list documents and read them.

Reasoning
Payroll month 2026-06 → first-half row. deduction_cap = 400.00.

R8: decision retrieve, field deduction_cap, value "400.00", clauses cite R1 and R4 (selecting rule R1 and source rule R4).

list_documents()
Reasoning
The task says "Retrieve deduction_cap from the supplied rulebook." But retrieval tasks require a payroll month. Hmm — "Retrieve the case inputs with list_documents and read_document." Let me check the documents first.

Actually the task is a retrieval task, but I need the payroll month from the case documents. Let me list documents.

lookup_reference(reference="first-half")lookup_reference(reference="second-half")
Reasoning
Payroll month 2026-06 → second-half reference (July–Dec)? Actually first-half = Jan–Jun, second-half = Jul–Dec. June is first-half presumably. But boundaries: "first-half and second-half". Let me lookup both? The rule says lookup_reference with first-half or second-half. June 2026 — likely first-half covers Jan-Jun. Let me look up first-half. But to be safe, I should check which row covers 2026-06. Let me query first-half and second-half.

Return retrieve answer with field deduction_cap, value "400.00", clauses ["R1","R4"].

lookup_reference(reference="second-half")
Reasoning
The payroll month is 2026-06 → second half. Retrieve deduction_cap from the reference. Use lookup_reference second-half.

Assistant
lookup_reference(reference="first-half")
Reasoning
Wait, second-half months listed as ["2026-07","2026-12"]? That seems like a range July to December. But payroll month is 2026-06, which is first half. Let me check first-half.

Assistant
{
  "decision": "retrieve",
  "field": "deduction_cap",
  "value": "400.00",

}
Reasoning
Payroll month 2026-06 falls in first-half (2026-01 to 2026-06). deduction_cap = 400.00. Cite R1 (selecting) and R4 (source rule).
