Reasoning
Let me start by listing documents and reading them, plus looking up reference tables.

lookup_reference(reference="first-half")lookup_reference(reference="second-half")
Reasoning
The payroll record has gross_pay = 6401.75, allowed_deduction = 314.85, but no payroll_month. Per R7 step 2: Missing payroll_month → clarify 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 the answer is clarify.

Do I need to check the reference tables? Not needed since the blocker is missing payroll_month. But should I still check? The rules say check in order: 1. missing gross_pay — present. 2. missing payroll_month — missing. So clarify.

For clarification: no monetary fields. Fields: decision, reason_code, clauses. Optional explanation naming the unresolved blocker and asking for resolution.

Note: allowed_deduction is present but the month is missing, so we can't select a reference row. The R4 fallback about accepting structurally valid deductions applies only for validation, not payslip calculation. The answer is clarify.

Cite R1 and R7.

}
Reasoning
The record has gross_pay = "6401.75" and allowed_deduction = "314.85", but no payroll_month. Per R7 order: gross_pay is present, payroll_month is missing → clarify with MISSING_PAYROLL_MONTH, citing R1 and R7. No monetary fields returned.

calculate(program="gross_pay = 6401.75\nallowed_deduction = 314.85")
Reasoning
The payroll record has gross_pay = 6401.75 and allowed_deduction = 314.85, but no payroll_month. Wait, let me check — the record only shows gross_pay and allowed_deduction. There's no payroll_month field.

Per R7: check required and conflicting inputs in order:
1. Missing gross_pay — gross_pay is present (6401.75).
2. Missing payroll_month — payroll_month is missing! So I should return clarify with reason_code MISSING_PAYROLL_MONTH, citing R1 and R7.

Wait, but maybe the payroll_month is elsewhere in the document. The document only shows {"kind": "payroll", "record": {"gross_pay": "6401.75", "allowed_deduction": "314.85"}}. No payroll_month.

So the answer is clarify with MISSING_PAYROLL_MONTH.

The answer fields for clarify: decision, reason_code, clauses. Plus optional explanation. Money fields should not be included for clarification cases ("For these cases do not return calculated monetary fields").

Let me double check the document — it's the only document. The record lacks payroll_month. So decision: clarify, reason_code: MISSING_PAYROLL_MONTH, clauses: ["R1", "R7"].

Explanation: The payroll record lacks payroll_month, which is required under R1; ask for the month.

Please provide the payroll month so the correct reference row can be selected and the payslip calculated."
}
Reasoning
The record has gross_pay and allowed_deduction but no payroll_month. Per R7 order of checks:
1. gross_pay present — OK.
2. payroll_month missing — clarify with MISSING_PAYROLL_MONTH, citing R1 and R7.

No reference row can be selected without a month, so no calculation. Return clarify JSON.

Under R1 a payroll month in YYYY-MM form is required, and R7 requires clarification when it is missing. Without a month no reference row can be selected, so no payslip can be calculated. Please provide the payroll month (within 2026) to proceed."
}
Reasoning
The payroll record has gross_pay "6401.75" and allowed_deduction "314.85", but no payroll_month. According to R7:

1. Missing gross_pay → MISSING_GROSS_PAY
2. Missing payroll_month → MISSING_PAYROLL_MONTH
3. No applicable reference
4. Conflicting gross pay

Here gross_pay is present, but payroll_month is missing. So the answer is clarify with reason_code "MISSING_PAYROLL_MONTH", citing R1 and R7.

The allowed_deduction is present but without a month/reference row we can't validate the cap; but per R7, missing payroll_month takes precedence in the ordered check. Order: 1. gross_pay missing? No. 2. payroll_month missing? Yes → clarify MISSING_PAYROLL_MONTH.

Return JSON: decision "clarify", reason_code "MISSING_PAYROLL_MONTH", clauses ["R1", "R7"], plus optional explanation. Do not include calculated monetary fields.
