list_documents()
Reasoning
Let me start by listing the documents and looking up the reference tables. Actually, I should first list documents to see what's in the case, and also I need to know the payroll month before looking up the reference. But the reference lookup requires knowing whether it's first-half or second-half, which depends on the payroll month. So first, list documents.

  "clauses": ["R1", "R7"],
  "explanation": "The payroll record supplies gross_pay (6072.36) and allowed_deduction (307.83) but omits payroll_month entirely. Under R1, payroll_month is a required field and the reference row is selected by payroll month; without it no applicable reference row can be determined, so no payslip can be calculated. Please provide the payroll month (YYYY-MM) so the correct first-half or second-half reference row can be selected."
}
```
Reasoning
The payroll record has gross_pay "6072.36" and allowed_deduction "307.83", but no payroll_month. Per R7 step 2: Missing payroll_month → decision "clarify", reason_code "MISSING_PAYROLL_MONTH", citing R1 and R7.

No monetary fields should be returned for clarification cases. The reason should name the unresolved blocker: payroll_month is missing, so no reference row can be selected.

Let me double check: the record has gross_pay present, so not MISSING_GROSS_PAY. payroll_month missing → MISSING_PAYROLL_MONTH. Cite R1 and R7.

No need for lookup_reference since we can't determine the month. The answer is a clarify JSON.

calculate(program="check = 1")
Reasoning
The payroll record has gross_pay = 6072.36 and allowed_deduction = 307.83, but there's no payroll_month. Per R7, missing payroll_month requires clarification with reason_code "MISSING_PAYROLL_MONTH", citing R1 and R7.

Wait, let me double-check the record. It only has gross_pay and allowed_deduction. No payroll_month field. So R7 order:
1. Missing gross_pay — no, gross_pay present.
2. Missing payroll_month — yes, missing. Return clarify with MISSING_PAYROLL_MONTH, citing R1 and R7.

The answer fields for clarify: decision, reason_code, clauses. Optional explanation string. Do not include calculated monetary fields.

}
Reasoning
The record is missing payroll_month. Per R7 step 2, return decision "clarify", reason_code "MISSING_PAYROLL_MONTH", citing R1 and R7. No monetary fields should be returned for clarification cases.

Now let me read the payroll document.

{
  "kind": "payroll",
  "record": {"gross_pay": "6072.36", "allowed_deduction": "307.83"}
}
Assistant
```json
{
  "decision": "clarify",
  "reason_code": "MISSING_PAYROLL_MONTH",
  "clauses": ["R1", "R7"],
  "explanation": "The payroll record supplies gross_pay (6072.36 LCR) and allowed_deduction (307.83 LCR) but omits payroll_month. A payroll month in YYYY-MM form is required to select the applicable reference row (contribution rate/cap, deduction cap, and tax brackets), and only 2026 months are covered. Please provide the payroll month so the calculation can proceed; do not infer it from document dates or assumptions."
}
```
Reasoning
The payroll record has gross_pay "6072.36" and allowed_deduction "307.83", but no payroll_month. Let me check the document again — the record only has gross_pay and allowed_deduction. No payroll_month field.

Per R7:
1. Missing gross_pay — no, gross_pay is present.
2. Missing payroll_month — yes, payroll_month is missing. Return decision: "clarify", reason_code: "MISSING_PAYROLL_MONTH", citing R1 and R7.

Wait, let me double-check the document. The record is {"kind": "payroll", "record": {"gross_pay": "6072.36", "allowed_deduction": "307.83"}}. No payroll_month, no contract_gross_pay, no amendment.

So the answer is clarify with MISSING_PAYROLL_MONTH, citing R1 and R7.

For clarification include a short explanation naming the unresolved blocker and asking for its resolution.

Fields for clarify: decision, reason_code, clauses. Optional explanation. No monetary fields.

Money must be strings with two decimals — but clarify doesn't include monetary fields. Good.
