lookup_reference(reference="second-half")
Reasoning
The payroll record has payroll_month "2026-12" and allowed_deduction "354.30", but gross_pay is missing.

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

Check order: first missing gross_pay — yes, it's missing. So we return clarify with MISSING_GROSS_PAY.

We don't need to look up reference rows since the first check fails. The answer should not include calculated monetary fields. Allowed fields for clarify: decision, reason_code, clauses. Optional explanation string permitted.

Money fields must not be included. The allowed_deduction present is input-only; do not include it.

Citations: R1 and R7.

  "explanation": "The payroll record for 2026-12 lacks gross_pay, which R1 requires. Although a reference row exists for that month (second-half: rate 0.04, cap 3500.00, deduction cap 400.00) and the supplied allowed_deduction of 354.30 is within the cap, no payslip can be calculated without gross pay. Please supply the missing gross_pay; per R7 no value may be guessed or substituted with zero."
}
Reasoning
The reference row exists for 2026-12 (second-half covers 2026-07 through 2026-12). However, gross_pay is missing. Per R7, check order:

1. Missing gross_pay → clarify with MISSING_GROSS_PAY, citing R1 and R7.

Even though a reference row exists, the first check fails. Do not calculate. Do not return monetary fields. The record also has allowed_deduction "354.30" which is structurally valid (≤ 400.00 cap), but we cannot compute anything without gross pay. Per R7: "Do not guess a value or substitute zero."

Return clarify JSON with decision, reason_code, clauses (R1, R7), and a short explanation.

}
Reasoning
The payroll record has:
- payroll_month: 2026-12
- allowed_deduction: 354.30
- gross_pay: MISSING

Per R7: Missing `gross_pay` → decision "clarify", reason_code "MISSING_GROSS_PAY", citing R1 and R7.

Check order:
1. Missing gross_pay → clarify with MISSING_GROSS_PAY, citing R1 and R7.

Payroll month is present (2026-12), so no missing month. Gross pay is missing. So we return clarify.

The answer fields for clarify: decision, reason_code, clauses. Optional explanation string. No monetary fields.

Do I need to check the reference tables? No — the first check fails. Missing gross_pay is the first check in order. So return clarify.

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

  "explanation": "The 2026-12 payroll record supplies only payroll_month and allowed_deduction; gross_pay is missing, which R1 requires and R7 item 1 flags before any calculation. Please provide the employee's monthly gross pay so the payslip can be computed."
}
Reasoning
The payroll record has:
- payroll_month: 2026-12
- allowed_deduction: 354.30
- No gross_pay!

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

The payroll month is 2026-12, which is covered (2026 is covered). But gross_pay is missing. So the first check applies: MISSING_GROSS_PAY.

Do I need to look up the reference? The month is 2026-12, which is within 2026, so a reference row exists. But since gross_pay is missing, we clarify. The check order: missing gross_pay is check #1, so it comes first regardless.

Should I still look up the reference? Not needed for clarification. The answer fields for clarify: decision, reason_code, clauses. Optional explanation string.

Citations: R1 and R7.

Money fields: "For these cases do not return calculated monetary fields. Missing required values include explicit null." Hmm, "Missing required values include explicit null" — this means when a required value is missing, it should be represented as explicit null? But the allowed answer fields for clarify are only decision, reason_code, clauses (plus optional explanation). So we don't include gross_pay field. The instruction "Missing required values include explicit null" might apply to calculate answers... but clarify doesn't include monetary fields. Actually re-reading: "For these cases do not return calculated monetary fields." So just decision, reason_code, clauses, explanation.

Return JSON without Markdown fences. The output format: "Return one JSON object without Markdown fences or surrounding prose."

So the answer:
{
  "decision": "clarify",
  "reason_code": "MISSING_GROSS_PAY",
  "clauses": ["R1", "R7"],
  "explanation": "The payroll record for 2026-12 lacks gross_pay..."
}

Wait — should the explanation ask for resolution? "For clarification include a short explanation naming the unresolved blocker and asking for its resolution."

Yes, include a short explanation asking for gross_pay.
