Let me start by listing the documents to get the case inputs.

The payroll record has gross_pay 5759.84, payroll_month 2026-04, allowed_deduction 67.09. The contract has gross_pay 5759.85, which differs from the payroll gross_pay.

R7 step 4: If optional `contract_gross_pay` is present and differs from `gross_pay`, neither source takes precedence unless an approved amendment resolves it under R9. Otherwise return clarify with CONFLICTING_GROSS_PAY, citing R7 and R9.

There's no amendment in the documents. So this is a conflicting gross pay case → clarify with reason_code CONFLICTING_GROSS_PAY, citing R7 and R9.

Wait — let me check: the payroll record doesn't include an amendment field. The contract gross_pay 5759.85 differs from payroll gross_pay 5759.84. No amendment is present. So per R7.4, decision: clarify, reason_code: CONFLICTING_GROSS_PAY, citing R7 and R9.

Do I need to check the reference row? No — the conflict check happens before calculation. The order in R7: 1. missing gross_pay — no. 2. missing payroll_month — no. 3. month without reference row — 2026-04 is covered (2026 is covered). 4. contract conflict — yes, conflict exists.

Actually, should I check step 3 before step 4? The order is: missing gross_pay, missing payroll_month, no reference row, conflicting gross pay. 2026-04 is within 2026, so covered. Then step 4: conflict. So clarify with CONFLICTING_GROSS_PAY.

For clarification, do not return calculated monetary fields. Include reason_code, clauses R7 and R9, and a short explanation naming the unresolved blocker and asking for its resolution.

The answer format: clarify uses decision, reason_code, clauses. Optional explanation string. Money fields not included for clarify.

Let me write the JSON:

{
  "decision": "clarify",
  "reason_code": "CONFLICTING_GROSS_PAY",
  "clauses": ["R7", "R9"],
  "explanation": "The payroll record reports gross_pay 5759.84 LCR for 2026-04, but the contract states gross_pay 5759.85 LCR. No approved amendment with effective month no later than 2026-04 and matching amount is supplied, so neither source takes precedence. Please provide an approved amendment under R9 or otherwise resolve the conflict before payroll can be calculated."
}

No need for lookup_reference or calculate since we're clarifying. The conflict is determined before calculation. I don't need the reference row for the clarify decision.

Let me start by listing the documents to see the case inputs.

The payroll record has gross_pay 5759.84, payroll_month 2026-04, allowed_deduction 67.09. The contract has gross_pay 5759.85 — but wait, R7 step 4 says: "If optional `contract_gross_pay` is present and differs from `gross_pay`, neither source takes precedence unless an approved amendment resolves it under R9."

Hmm, but the contract is a separate document, not an optional `contract_gross_pay` field in the payroll record. Let me think. The rule says "If optional `contract_gross_pay` is present and differs from `gross_pay`". The contract document has gross_pay 5759.85 which differs from payroll gross_pay 5759.84. Is this a conflicting gross pay situation?

R9 says: "An optional `amendment` has `gross_pay`, `effective_month`, and boolean `approved`. It resolves a contract conflict only if it is approved, its effective month is no later than the payroll month, and its amount equals the payroll record's gross pay. It does not automatically change gross pay. A draft, future, or different-amount amendment does not resolve a conflict. Matching contract values require no amendment. Never infer a missing gross pay from a contract or amendment."

There's no amendment here. The contract gross pay (5759.85) differs from payroll gross pay (5759.84) by one cent. There's no amendment to resolve it. So this is a CONFLICTING_GROSS_PAY case → clarify with reason_code "CONFLICTING_GROSS_PAY", citing R7 and R9.

Wait, but should I consider the contract document as the "contract_gross_pay"? The task format includes documents: payroll and contract. The contract's gross_pay field is the contract_gross_pay. It differs from the payroll record's gross_pay. Per R7 step 4, since there's no approved amendment resolving it, return clarify with CONFLICTING_GROSS_PAY.

Hmm, but let me double-check: is the difference meaningful? 5759.84 vs 5759.85 — yes, they differ. "Matching contract values require no amendment." These don't match. No amendment exists. So conflict is unresolved → clarify.

Also check the month: 2026-04 is covered by reference rows (only 2026 is covered). But since we're clarifying on the conflict, we don't calculate.

Order of checks in R7:
1. Missing gross_pay — present (5759.84).
2. Missing payroll_month — present (2026-04).
3. Month without reference row — 2026-04 is in 2026, covered.
4. contract_gross_pay present and differs — yes → CONFLICTING_GROSS_PAY.

So the answer is clarify with reason_code CONFLICTING_GROSS_PAY, citing R7 and R9.

For clarify: fields are decision, reason_code, clauses. Optional explanation string permitted. No monetary fields.

Explanation: The contract gross pay (5759.85 LCR) differs from the payroll record gross pay (5759.84 LCR) and no approved amendment resolves the conflict; please provide an approved amendment or corrected values.

Clauses: R7 and R9.

Should I cite R1 too? The rule says "Unresolved contract conflicts cite R7 and R9." So clauses: ["R7", "R9"].

No need for lookup_reference or calculate since we're clarifying. The month check passed anyway (2026-04 is covered), but the conflict blocks calculation.

Let me produce the JSON object without Markdown fences.

Let me start by listing the documents to get the case inputs.

The payroll record: gross_pay 5759.84, payroll_month 2026-04, allowed_deduction 67.09. Contract gross_pay 5759.85 differs from payroll gross_pay 5759.84.

R7 step 4: If optional contract_gross_pay is present and differs from gross_pay, neither source takes precedence unless an approved amendment resolves it under R9. There's no amendment here. So this is a CONFLICTING_GROSS_PAY clarification, citing R7 and R9.

Wait — check: contract gross_pay 5759.85 vs payroll 5759.84. They differ by 0.01. No amendment present. So decision: clarify, reason_code: CONFLICTING_GROSS_PAY, clauses R7 and R9.

The order of checks in R7: 1. missing gross_pay — present. 2. missing payroll_month — present. 3. month without reference row — 2026-04 is covered (only 2026 covered). 4. contract conflict — yes, conflict exists.

Hmm, but should I check the reference row first? The order given: check required and conflicting inputs in this order. Step 4 is the contract conflict. The month 2026-04 is within 2026, so covered. So the conflict triggers clarify.

Per R7: "For these cases do not return calculated monetary fields." So answer: decision clarify, reason_code CONFLICTING_GROSS_PAY, clauses ["R7", "R9"], plus explanation.

Money fields as strings with two decimals — but for clarify we don't return monetary fields. Allowed answer fields for clarify: decision, reason_code, clauses. Optional explanation string.

Let me write the JSON without markdown fences. The instructions say "Return one JSON object without Markdown fences or surrounding prose." So output raw JSON.
