lookup_reference(reference="first-half")lookup_reference(reference="second-half")
Reasoning
The payroll record has payroll_month 2026-04 but no gross_pay. Missing gross_pay → clarify MISSING_GROSS_PAY, citing R1 and R7. Check order: 1. Missing gross_pay first. So decision clarify.

  "explanation": "The payroll record supplies payroll_month 2026-04 but no gross_pay. Please provide the monthly gross pay so the payroll can be calculated."
}
Reasoning
The payroll record lacks gross_pay (it's missing entirely, which counts as missing per R7: "Missing required values include explicit null" - actually it says missing required values include explicit null; here it's just absent). Either way, missing gross_pay → clarify MISSING_GROSS_PAY, cite R1 and R7.

A reference row exists for 2026-04 (first-half covers 2026-01 through 2026-06 per "2026-01", "2026-06" range presumably). But check order: gross_pay missing is checked first.

Return clarify with reason_code MISSING_GROSS_PAY, clauses R1, R7.

  "clauses": ["R1", "R7"],
  "explanation": "The payroll record for 2026-04 has no gross_pay value, so the required input is missing. Please supply the gross_pay amount for this month."
}
Reasoning
The payroll record has payroll_month "2026-04" but no gross_pay (missing entirely). R7 rule 1: Missing gross_pay → clarify MISSING_GROSS_PAY, citing R1 and R7. Explicit missing values count. The document contains only payroll_month. So gross_pay is missing → clarify.

Check order: gross_pay missing first. Yes.

Return clarify with reason_code MISSING_GROSS_PAY, clauses R1, R7. Short explanation naming the blocker and asking for resolution.

Assistant
read_document(document_id="b256826a42768acd-payroll")
Reasoning
Read the payroll document. Also there might be a reference_tables document. Let me read the payroll doc first.
Tool
{
  "kind": "payroll",
  "record": {"payroll_month": "2026-04"}
}
Assistant
{
  "decision": "clarify",
  "reason_code": "MISSING_GROSS_PAY",
  "clauses": ["R1", "R7"],
  "explanation": "The payroll record for 2026-04 has no gross_pay value. Please supply the gross pay amount so the payroll can be calculated."
}
Reasoning
The payroll record only has payroll_month 2026-04, no gross_pay. So missing gross_pay -> clarify MISSING_GROSS_PAY, citing R1 and R7.

Wait, but maybe there are more documents? list_documents returned only one. So gross_pay is missing. Decision: clarify, reason_code MISSING_GROSS_PAY.

Clause order: check in order — missing gross_pay first. Cite R1 and R7.
