read_document(document_id="3306732e853a7389-payroll")
Reasoning 
Read the payroll document.

  "decision": "clarify",

  "clauses": ["R1", "R7"],
  "explanation": "The payroll record provides gross_pay but the required payroll_month is missing, so no reference row can be selected. Please supply the payroll month in YYYY-MM format."
}
Reasoning 
The record has gross_pay but no payroll_month. Per R7 order: check gross_pay present (yes), then payroll_month missing → clarify MISSING_PAYROLL_MONTH citing R1 and R7.

Wait, but payroll_month might be elsewhere? The record only contains gross_pay and allowed_deduction. So payroll_month is missing → clarify.

Reasoning 
Read the document.

  "record": {"gross_pay": "2524.56", "allowed_deduction": "208.50"}

  "clauses": ["R1", "R7"],
  "explanation": "The payroll record has no payroll_month, so no reference row can be selected. Please supply the payroll month in YYYY-MM format within 2026."
}
Reasoning 
The payroll record is missing `payroll_month`. Per R7 order: missing gross_pay first — gross_pay present. Missing payroll_month → clarify MISSING_PAYROLL_MONTH, cite R1 and R7.

Wait, but maybe there are other documents? Only one. So payroll_month is missing. Return clarify with reason_code MISSING_PAYROLL_MONTH, clauses R1, R7.

Should I call lookup_reference? Not needed since we clarify on missing month. The order of checks: gross_pay present, then payroll_month missing → clarify. Do not return monetary fields.

read_document(document_id="3306732e853a7389-payroll")
Reasoning 
Read the payroll document. Also might need reference lookup. Let me read the document first.
Tool
{
  "kind": "payroll",
  "record": {"gross_pay": "2524.56", "allowed_deduction": "208.50"}
}
Assistant
{
  "decision": "clarify",
  "reason_code": "MISSING_PAYROLL_MONTH",
  "clauses": ["R1", "R7"],
  "explanation": "The payroll record does not supply the required payroll_month (missing required values include explicit null). Please provide the payroll month in YYYY-MM format within 2026 so the correct reference row can be selected and the payroll calculated."
}
Reasoning 
Missing payroll_month. Per R7 step 2: MISSING_PAYROLL_MONTH, citing R1 and R7. Note: order of checks — missing gross_pay first (gross_pay present), then missing payroll_month. payroll_month is absent (missing required values include explicit null — here it's just absent). So clarify.

Wait, but maybe other documents exist? Only one document. So payroll_month is missing. Return clarify with reason_code MISSING_PAYROLL_MONTH, clauses R1, R7.

Also there might be a trap: R4 says when month absent, accept structurally valid deductions... but that's for deduction validation, not to calculate. Clarification takes precedence per R7 order.

Return JSON with decision, reason_code, clauses, optional explanation.
