Reasoning
Let me list documents first.

read_document(document_id="dabcba8c02ca6959-payroll")
Reasoning
Read the payroll document.
Tool
{
  "kind": "payroll",
  "record": {"gross_pay": "5370.93", "allowed_deduction": "379.49"}
}
Assistant
{
  "decision": "clarify",
  "reason_code": "MISSING_PAYROLL_MONTH",
  "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
No payroll_month provided. Missing payroll_month → clarify with MISSING_PAYROLL_MONTH, cite R1 and R7.

Wait - check order: gross_pay is present, payroll_month missing. So reason_code MISSING_PAYROLL_MONTH.

But wait, maybe there are more documents? Only one. The record lacks payroll_month. Per R7, check order: missing gross_pay first (gross_pay present), then missing payroll_month → clarify MISSING_PAYROLL_MONTH.

read_document(document_id="dabcba8c02ca6959-payroll")
Reasoning
Read it.
Tool
{
  "kind": "payroll",
  "record": {"gross_pay": "5370.93", "allowed_deduction": "379.49"}
}
Assistant
{
  "decision": "clarify",
  "reason_code": "MISSING_PAYROLL_MONTH",
  "clauses": ["R1", "R7"],
  "explanation": "The payroll record provides gross_pay and allowed_deduction but no payroll_month. Please supply the payroll month in YYYY-MM format within 2026 so the correct reference row can be selected."
}
Reasoning
Missing payroll_month. Check R7 order: 1. Missing gross_pay? No, gross_pay present. 2. Missing payroll_month? Yes → clarify MISSING_PAYROLL_MONTH, cite R1 and R7.

Wait — but the case might have other documents? Only one document. payroll_month is missing (explicitly absent, not null but missing). Required check order: gross_pay present, payroll_month missing → MISSING_PAYROLL_MONTH.

But wait, is gross_pay "explicit null"? No, it's present. So decision: clarify, reason_code: MISSING_PAYROLL_MONTH, clauses R1, R7.

  "clauses": ["R1", "R7"]
}
Reasoning
The payroll record has gross_pay and allowed_deduction but no payroll_month! Missing payroll_month → clarify MISSING_PAYROLL_MONTH, citing R1 and R7.

Wait — the record only has gross_pay and allowed_deduction. No payroll_month. Per R7 check order: gross_pay present, payroll_month missing → clarify MISSING_PAYROLL_MONTH.

Also no contract_gross_pay, no amendment. So decision: clarify, reason_code MISSING_PAYROLL_MONTH, clauses ["R1","R7"].
