Read the payroll document.

  "decision": "clarify",

  "clauses": ["R1", "R7"],
  "explanation": "The payroll record for 2026-01 does not include gross_pay, which is required by R1. Please supply the gross pay amount so the payroll can be calculated."
}
Reasoning
The payroll record has payroll_month 2026-01 and allowed_deduction 341.21, but gross_pay is missing (or perhaps absent). Wait — "Missing required values include explicit null." Here gross_pay is simply absent. Either way, missing gross_pay → clarify MISSING_GROSS_PAY, cite R1 and R7.

Check order: 1. Missing gross_pay first. Yes.

Should I look up reference? Not necessary, since clarification check order puts missing gross_pay first. But it doesn't hurt. The answer: decision clarify, reason_code MISSING_GROSS_PAY, clauses ["R1","R7"], explanation naming blocker.

Let me start by listing documents.

read_document(document_id="8ad5ac011f1341dc-payroll")
Reasoning
Read the payroll document.
Tool
{
  "kind": "payroll",
  "record": {"payroll_month": "2026-01", "allowed_deduction": "341.21"}
}
Assistant
{
  "decision": "clarify",
  "reason_code": "MISSING_GROSS_PAY",
  "clauses": ["R1", "R7"],
  "explanation": "The payroll record omits required gross_pay, so the monthly payroll cannot be calculated. Please supply gross_pay for 2026-01."
}
Reasoning
The payroll record has payroll_month "2026-01" and allowed_deduction "341.21", but no gross_pay. Missing gross_pay → clarify with MISSING_GROSS_PAY, citing R1 and R7. Explicit missing (omitted counts as missing; R7 says missing required values include explicit null).

Check order: 1. Missing gross_pay first. So decision clarify, reason_code MISSING_GROSS_PAY.

Should I check the reference row? No — clarification order puts missing gross_pay first. But let me maybe still lookup reference to confirm deduction cap? Not needed; answer is clarify. But allowed_deduction 341.21 — R4 says when month or row absent, but here gross pay missing so no calculation. Answer fields: decision, reason_code, clauses. No monetary fields.

Reasoning
Gross pay is missing. Per R7 order, check 1: missing gross_pay -> clarify MISSING_GROSS_PAY, citing R1 and R7. Do not return monetary fields.
