}
Reasoning
The payroll record has no gross_pay. Missing gross_pay → clarify MISSING_GROSS_PAY, cite R1 and R7. Month 2026-11 is covered by second-half row, so no issue there. But missing gross_pay check comes first (order 1).

Reasoning
The payroll record has payroll_month 2026-11 and allowed_deduction 0.00, but no gross_pay. Missing gross_pay → clarify with MISSING_GROSS_PAY, citing R1 and R7.

Wait — R7 order: check missing gross_pay first. Yes, gross_pay is missing (absent). "Missing required values include explicit null." Here it's absent entirely. So clarify MISSING_GROSS_PAY.

But wait, also month 2026-11 — is there a reference row? Let me check. R7 order says check missing gross_pay first. But should I look up reference? The order says gross_pay first. Even though the month might lack a reference, the check order is: 1. Missing gross_pay. So decision is MISSING_GROSS_PAY.

Hmm, but maybe I should verify reference rows anyway for due diligence. The rules say check in this order. Missing gross_pay is checked first and returns clarify. Let me just confirm reference lookups to be thorough — but it doesn't change the answer. Actually the order is explicit: return MISSING_GROSS_PAY. I'll do the lookup anyway to be careful but the answer stands.

Actually, to keep it simple and correct per order, I can answer now. But let me quickly look up references to verify facts. It's allowed. The final answer: clarify, MISSING_GROSS_PAY, clauses R1 and R7.
