calculate(program="check = 1")
Reasoning
The payroll record has only `payroll_month: 2026-09`, no `gross_pay`. Per R7 order of checks:

1. Missing `gross_pay`: return `decision: "clarify"` and `reason_code: "MISSING_GROSS_PAY"`, citing R1 and R7.

So the answer is clarify with MISSING_GROSS_PAY. I don't need lookup_reference or calculate since the calculation can't proceed. The clarify answer fields: decision, reason_code, clauses, optional explanation.

Clauses: R1 and R7.

  "explanation": "The payroll record for 2026-09 contains only payroll_month and no gross_pay. R1 requires gross_pay for every calculation, and R7 directs clarification with reason_code MISSING_GROSS_PAY when it is missing. Please supply the gross pay so the payslip can be calculated."
}
Reasoning
The payroll record is missing gross_pay entirely. Under R7 check order, item 1: Missing gross_pay → clarify with reason_code MISSING_GROSS_PAY, citing R1 and R7. No monetary fields should be returned.

lookup_reference(reference="second-half")
Reasoning
The payroll record has only `payroll_month: "2026-09"` — no `gross_pay`. Per R7 step 1: Missing `gross_pay` → clarify with reason_code "MISSING_GROSS_PAY", citing R1 and R7.

Wait, let me double-check the document. It only contains payroll_month. No gross_pay, no contract_gross_pay, no amendment. So the blocker is missing gross_pay.

Per R7: "Missing required values include explicit null." Hmm — "Missing required values include explicit null." That means explicit nulls count as missing. Here gross_pay is absent entirely, which is missing.

Should I still look up the reference? The month 2026-09 is covered (only 2026 is covered), but the missing gross_pay check comes first in the order (step 1 before step 3). So decision: clarify, reason_code: MISSING_GROSS_PAY, citing R1 and R7.

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

I don't strictly need lookup_reference since the blocker is missing gross_pay, and R7 order says missing gross_pay is checked first. I could optionally verify the month has a reference row, but the clarification reason is determined by the first check. The rules say check in this order; step 1 triggers first. I'll just return clarify.

Fields: decision, reason_code, clauses. Explanation naming the unresolved blocker and asking for its resolution.

  "explanation": "The payroll record for 2026-09 contains only payroll_month and no gross_pay (explicitly absent, treated as missing under R7). Gross pay is required by R1, so no payslip can be calculated even though 2026-09 has an applicable reference row. Please supply the employee's monthly gross_pay (and any allowed_deduction) to resolve this blocker."
}
Reasoning
The month 2026-09 is covered by the second-half reference row (months 2026-07 through 2026-12). But the record has no gross_pay at all. Per R7 order, step 1 applies: missing gross_pay → clarify with MISSING_GROSS_PAY, citing R1 and R7.

lookup_reference(reference="second-half")
Reasoning
The payroll record only has `payroll_month: "2026-09"` and no `gross_pay`. According to R7, the check order is:

1. Missing `gross_pay`: return `decision: "clarify"` and `reason_code: "MISSING_GROSS_PAY"`, citing R1 and R7.

So the answer is clarify with MISSING_GROSS_PAY. No monetary fields. Should I check the reference tables? Not needed — gross pay is missing, so clarification is required regardless. The order of checks: missing gross_pay is checked first.

The answer format: clarify uses decision, reason_code, clauses. Optional explanation string naming the unresolved blocker and asking for its resolution.

Clauses: R1 and R7.

  "reason_code": "MISSING_GROSS_PAY",
  "clauses": ["R1", "R7"],
  "explanation": "The payroll record for 2026-09 contains only payroll_month and omits gross_pay, which is a required field under R1. Although a second-half reference row (2026-07 through 2026-12) covers the month, no payslip can be computed without gross pay. Please supply the employee's monthly gross_pay for 2026-09 so the calculation can proceed."
}
```
Reasoning
The month 2026-09 falls within the second-half row (2026-07 through 2026-12), so a reference row exists. However, the payroll record is missing `gross_pay`. Per R7 check order, item 1: Missing `gross_pay` → clarify with reason_code "MISSING_GROSS_PAY", citing R1 and R7.

I don't need to calculate anything since gross pay is missing. Return the clarify JSON.
