Reasoning
The payroll record has gross_pay and allowed_deduction, but no payroll_month. Missing payroll_month → clarify MISSING_PAYROLL_MONTH, citing R1 and R7.

Wait, let me check for other documents. Only one document. So no payroll_month provided. Actually the record doesn't include payroll_month. R7 step 2: missing payroll_month → clarify.

But wait — should I check for reference rows? The month is missing, so we can't select. Return clarify.

Let me double check whether there's a payroll_month hidden. The record is {"gross_pay": "5370.93", "allowed_deduction": "379.49"}. No month. So MISSING_PAYROLL_MONTH.

R7 order: 1. missing gross_pay — no, present. 2. missing payroll_month — yes. Return clarify MISSING_PAYROLL_MONTH citing R1 and R7.

Reasoning
The payroll record has no payroll_month. So we cannot select a reference row. R7 step 2: missing payroll_month → MISSING_PAYROLL_MONTH.

Return clarify.

The payroll record contains `gross_pay` and `allowed_deduction` but no `payroll_month`, so the reference row cannot be selected and no payslip can be computed.

```json
{
  "decision": "clarify",
  "reason_code": "MISSING_PAYROLL_MONTH",
  "clauses": ["R1", "R7"],
  "explanation": "The record is missing the required payroll_month, so no reference row can be selected and payroll cannot be calculated. Please provide the payroll month in YYYY-MM format (a month covered by a reference row, i.e., 2026)."
}
```
Reasoning
The payroll record has gross_pay 5370.93 and allowed_deduction 379.49, but no payroll_month. Wait, let me check - the record doesn't include payroll_month. Hmm.

Missing payroll_month -> return clarify MISSING_PAYROLL_MONTH citing R1 and R7.

Wait, but let me double-check. The record: {"gross_pay": "5370.93", "allowed_deduction": "379.49"}. No payroll_month. So R7 step 2: missing payroll_month -> clarify.

Let me verify there's no other document. Only one document. So payroll_month is missing.

Actually wait, let me re-read. The task says "Process this monthly payroll record". The record has gross_pay and allowed_deduction but no payroll_month. So missing payroll_month.

R7 order: 1. missing gross_pay - no, present. 2. missing payroll_month - yes. Return clarify MISSING_PAYROLL_MONTH citing R1 and R7.

Let me confirm there's no payroll_month field hidden. The record is exactly {"gross_pay": "5370.93", "allowed_deduction": "379.49"}. Yes missing.

So answer: decision clarify, reason_code MISSING_PAYROLL_MONTH, clauses [R1, R7], explanation.

  "clauses": ["R1", "R7"],
  "explanation": "The payroll record supplies gross_pay and allowed_deduction but no payroll_month. R1 requires payroll_month to select the applicable reference row, so the payroll month is the unresolved blocker. Please provide the payroll month in YYYY-MM format (2026) to proceed."
}
Reasoning
The record has gross_pay and allowed_deduction but no payroll_month. Wait, payroll_month is required. Let me check. The record doesn't include payroll_month. Hmm, but maybe the payroll_month is elsewhere? Let me re-read the document. It only has gross_pay and allowed_deduction. No payroll_month.

Wait, R1 says gross_pay and payroll_month are required. Missing payroll_month → clarify MISSING_PAYROLL_MONTH.

But wait, maybe there's a reference table lookup needed. Let me check the reference tables to see if they have effective months. Actually, we need to know the payroll month to select the row. The record doesn't include payroll_month.

Hmm, but maybe the payroll_month is implied by the document? Let me look more carefully. The record only contains gross_pay and allowed_deduction. So payroll_month is missing.

Actually wait — let me double check whether there might be additional fields. The record is {"gross_pay": "5370.93", "allowed_deduction": "379.49"}. No payroll_month, no contract_gross_pay, no amendment.

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

But hold on — maybe I should check the reference tables to be thorough. Actually the order of checks: 1. Missing gross_pay -> not. 2. Missing payroll_month -> yes. So MISSING_PAYROLL_MONTH.

Let me verify there's no payroll_month hidden. The document read returned exactly that. Let me also consider that maybe there are other documents. list_documents returned only one.

So decision: clarify, reason_code: MISSING_PAYROLL_MONTH, clauses: ["R1","R7"], explanation naming the unresolved blocker.

Let me produce that.

Actually, let me reconsider. Could payroll_month be provided in the task prompt? The prompt says "Process this monthly payroll record under the supplied rulebook." No month given. So it's missing.
