  "explanation": "The payroll month is unresolved, so the applicable reference row cannot be selected. Please supply the payroll month in YYYY-MM format."
}
Reasoning
The payroll month is missing! The record only has gross_pay and allowed_deduction. Per R7, missing payroll_month -> clarify MISSING_PAYROLL_MONTH.

But wait - the source document is given without payroll_month. Required check order: missing gross_pay first (present), missing payroll_month (absent) -> clarify.

Answer: decision clarify, reason_code MISSING_PAYROLL_MONTH, clauses R1, R7, explanation.

No monetary fields.

  "clauses": ["R1", "R7"]
}
Reasoning
There is no payroll_month! Required. Gross pay exists, but payroll_month missing -> clarify MISSING_PAYROLL_MONTH, cite R1 and R7. Order: missing gross_pay first — gross present. So MISSING_PAYROLL_MONTH.

Allowed deduction: 307.83 structurally valid... but month absent anyway.

Return clarify.

}
Reasoning
Payroll month missing! Check order: gross_pay present, payroll_month missing -> clarify MISSING_PAYROLL_MONTH. Cite R1 and R7. But wait — is payroll_month missing? The record has gross_pay and allowed_deduction only. Yes, missing payroll_month. Return clarify.

Hmm, but the reference schedule is supplied. But no payroll month -> MISSING_PAYROLL_MONTH.

Also check if gross_pay missing first: no, present. So MISSING_PAYROLL_MONTH.

Return JSON with decision, reason_code, clauses, explanation.
