lookup_reference(reference="first-half")lookup_reference(reference="second-half")
Reasoning
The payroll record has payroll_month 2026-01 and allowed_deduction 345.85, but no gross_pay. Missing gross_pay → clarify MISSING_GROSS_PAY citing R1 and R7.

Wait, but let me check - maybe there are other documents? Only one document listed. gross_pay is missing (explicitly absent, not even null). R7 order: 1. Missing gross_pay → clarify MISSING_GROSS_PAY.

Should I still look up the reference? Not necessary for the answer but the deduction check... R4 says when month or applicable row is absent, accept structurally valid deductions up to largest cap. But here we have a month with a row likely. However, the missing gross_pay check comes first in R7's order. So return clarify MISSING_GROSS_PAY.

Clauses: R1 and R7. Explanation naming unresolved blocker and asking for resolution.

}
Reasoning
The payroll record for 2026-01 has no gross_pay field. Per R7 step 1, missing gross_pay (required value absent) → clarify MISSING_GROSS_PAY, citing R1 and R7. The month 2026-01 has a reference row (first-half covers 2026-01), but the check order puts missing gross_pay first.

}
Reasoning
The payroll record has payroll_month "2026-01" and allowed_deduction "345.85", but no gross_pay. Per R7, missing gross_pay (explicit null or absent) → clarify MISSING_GROSS_PAY.

Wait — gross_pay is missing entirely. R7 check order: 1. Missing gross_pay → clarify MISSING_GROSS_PAY, citing R1 and R7.

There is no contract_gross_pay or amendment document. Only one document. So decision: clarify, reason_code: MISSING_GROSS_PAY, clauses: ["R1", "R7"].

But wait, should I check the reference row first? R7 order says missing gross_pay is checked first. Also no need to lookup reference since clarification for missing gross pay takes precedence. The order: check required and conflicting inputs in this order. Missing gross_pay is #1. So return clarify.

Fields: decision, reason_code, clauses, explanation. No monetary fields.

calculate(program="gross_present = 0")
Reasoning
The payroll record has payroll_month "2026-01" and allowed_deduction "345.85", but no gross_pay. Missing gross_pay → clarify with MISSING_GROSS_PAY, citing R1 and R7.

Wait — check for contract_gross_pay? The record only shows payroll_month and allowed_deduction. Missing gross_pay is explicit absence (not null, just missing). R7 item 1: Missing gross_pay → clarify MISSING_GROSS_PAY, citing R1 and R7.

No lookup needed since clarification is ordered first. But maybe I should check reference anyway? Order of checks: missing gross_pay is first. So clarify.
