Reasoning
The payroll record has gross_pay = 5370.93 and allowed_deduction = 379.49, but no payroll_month. According to R7, missing payroll_month requires clarification with reason_code "MISSING_PAYROLL_MONTH", citing R1 and R7.

Wait, let me check the order of checks:
1. Missing gross_pay → MISSING_GROSS_PAY
2. Missing payroll_month → MISSING_PAYROLL_MONTH
3. Month without reference row → NO_APPLICABLE_REFERENCE
4. Conflicting gross_pay → CONFLICTING_GROSS_PAY

Gross pay is present (5370.93). Payroll month is missing. So decision: clarify, reason_code: MISSING_PAYROLL_MONTH, citing R1 and R7.

The record has no payroll_month field at all. Also no contract_gross_pay or amendment. So the answer is clarify.

Fields for clarify: decision, reason_code, clauses, and optional explanation. Money fields should not be returned for clarification cases.

R1 requires a payroll month in YYYY-MM format to select the applicable reference row, and R7 requires clarification when payroll_month is missing. Please provide the payroll month so the correct reference row can be selected and the payslip calculated."
}
Reasoning
The record is missing payroll_month entirely. Per R7 check order: gross_pay is present, so check 1 passes. Check 2: payroll_month is missing → clarify with MISSING_PAYROLL_MONTH, citing R1 and R7. No calculated monetary fields should be returned.

Reasoning
The payroll record has gross_pay "5370.93" and allowed_deduction "379.49", but no payroll_month. Let me check the reference tables — but first, the missing payroll_month is a blocker.

Wait, per R7 order:
1. Missing gross_pay → no, gross_pay is present.
2. Missing payroll_month → yes, missing. Return clarify with reason_code "MISSING_PAYROLL_MONTH", citing R1 and R7.

But should I check the reference tables first? The record has no payroll_month, so no reference row can be selected. The clarification order says check missing payroll_month as item 2. There's no month to look up. So the answer is clarify with MISSING_PAYROLL_MONTH.

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

Citations: R1 and R7.

The payroll record supplies `gross_pay` (5370.93) and `allowed_deduction` (379.49), but no `payroll_month`. Without a month, no reference row can be selected (both halves of 2026 require a specific month), so per R7's ordered checks the missing month blocks calculation before any reference selection or payslip computation.

```json
{
  "decision": "clarify",
  "reason_code": "MISSING_PAYROLL_MONTH",
  "clauses": ["R1", "R7"],
  "explanation": "The payroll record is missing payroll_month, which R1 requires (format YYYY-MM). Please provide the payroll month so the applicable reference row can be selected and the payslip calculated."
}
```
Reasoning
The record has gross_pay "5370.93" and allowed_deduction "379.49" but no payroll_month. Per R7 order of checks:

1. Missing gross_pay — present, OK.
2. Missing payroll_month — missing → clarify with reason_code "MISSING_PAYROLL_MONTH", citing R1 and R7.

I cannot select a reference row without a month, so no payslip calculation. Return the clarify JSON.

}
Reasoning
The payroll record has gross_pay = 5370.93 and allowed_deduction = 379.49, but no payroll_month. Let me check the record again — it has "gross_pay" and "allowed_deduction" only. No payroll_month field.

Per R7: Missing payroll_month → clarify with reason_code "MISSING_PAYROLL_MONTH", citing R1 and R7.

Wait, but let me double-check the document — maybe there's more. The record shows only gross_pay and allowed_deduction. No payroll_month, no amendment, no contract_gross_pay.

Order of checks in R7:
1. Missing gross_pay — present, so no.
2. Missing payroll_month — missing → clarify MISSING_PAYROLL_MONTH, citing R1 and R7.

For clarification, no calculated monetary fields. Missing required values include explicit null — but the allowed answer fields for clarify are decision, reason_code, clauses, plus optional explanation. So I return decision: "clarify", reason_code: "MISSING_PAYROLL_MONTH", clauses: ["R1", "R7"], and a short explanation.

I don't need lookup_reference or calculate since we can't proceed without the month.
