  "clauses": ["R1", "R7"],
  "explanation": "The payroll record supplies gross_pay but no payroll_month, so the reference row cannot be selected. Please provide the payroll month in YYYY-MM format within 2026."
}
Reasoning
The payroll record has gross_pay 3203.76 and allowed_deduction 359.44, but no payroll_month. Per R7, missing payroll_month → clarify MISSING_PAYROLL_MONTH, citing R1 and R7. Check order: gross_pay present first? R7 order: 1. Missing gross_pay → MISSING_GROSS_PAY. 2. Missing payroll_month → MISSING_PAYROLL_MONTH.

gross_pay is present ("3203.76"). payroll_month is missing → clarify with MISSING_PAYROLL_MONTH, clauses R1, R7.

No monetary fields returned.

read_document(document_id="2735c93fe2c3ddab-payroll")
Reasoning
Read the payroll document. Also maybe other documents. Only one. Let me read it.
Tool
{
  "kind": "payroll",
  "record": {"gross_pay": "3203.76", "allowed_deduction": "359.44"}
}
Assistant
{
  "decision": "clarify",
  "reason_code": "MISSING_PAYROLL_MONTH",
  "clauses": ["R1", "R7"],
  "explanation": "The payroll record supplies gross_pay and allowed_deduction but no payroll_month (YYYY-MM). The payroll month is required to select the applicable reference row. Please provide the payroll month in YYYY-MM format within 2026."
}
Reasoning
The payroll record has gross_pay but no payroll_month. Wait — the task says "Process this monthly payroll record". The record lacks payroll_month. Per R7 order: 1. Missing gross_pay — no. 2. Missing payroll_month — yes, missing (explicitly absent). Return clarify MISSING_PAYROLL_MONTH citing R1 and R7.

But wait, maybe there are other documents? Only one document listed. So payroll_month is missing → clarify.

Should I check lookup_reference? Not needed since missing payroll_month triggers clarification first in order. The check order: gross_pay missing? No. payroll_month missing? Yes → clarify.

Return JSON with decision clarify, reason_code MISSING_PAYROLL_MONTH, clauses ["R1","R7"], explanation.

Reasoning
Read the payroll document.
Tool
{
  "kind": "payroll",
  "record": {"gross_pay": "3203.76", "allowed_deduction": "359.44"}
}
Assistant
{
  "decision": "clarify",
  "reason_code": "MISSING_PAYROLL_MONTH",
  "clauses": ["R1", "R7"],
  "explanation": "The payroll record omits the required payroll_month (YYYY-MM), so no reference row can be selected. Please supply the payroll month to proceed."
}
Reasoning
The record has gross_pay and allowed_deduction but no payroll_month. Per R7 check order:1. Missing gross_pay? No, gross_pay present. 2. Missing payroll_month? Yes — payroll_month is required and absent. Return clarify with MISSING_PAYROLL_MONTH, citing R1 and R7.

Wait — is payroll_month missing? The record only contains gross_pay and allowed_deduction. Yes, missing payroll_month. Explicit null counts as missing; absent is missing too.

So decision: clarify, reason_code: MISSING_PAYROLL_MONTH, clauses: R1, R7.
