Let me start by listing documents.

Let me read all documents.

Let me analyze.

Payroll record: gross_pay 3807.00, payroll_month 2026-04, allowed_deduction 181.70.

Contract gross_pay: 3807.01, differs from gross_pay 3807.00. So conflict.

Amendment: gross_pay 3807.00, approved true, effective_month 2026-06. But payroll month is 2026-04. Effective month must be no later than payroll month. 2026-06 > 2026-04, so future amendment does not resolve. So unresolved conflict → clarify, reason_code CONFLICTING_GROSS_PAY, citing R7 and R9.

Wait, check order of R7: 1 missing gross_pay, 2 missing payroll_month, 3 month without reference row, 4 conflict. First check month has reference row. 2026-04 is in 2026, so covered. Need to check reference row exists. Only 2026 covered. Let me check lookup_reference to confirm 2026-04 has a row.

Actually R1 says select the reference row using the payroll month. Let me check the reference tables.

Now, which reference row applies to 2026-04? The first-half months are 2026-01 through 2026-06, second-half 2026-07 through 2026-12. So 2026-04 is in first-half.

Now the conflict: contract gross_pay 3807.01 differs from gross_pay 3807.00. Amendment is approved but effective_month 2026-06 is later than payroll month 2026-04, so it does not resolve the conflict.

Therefore return clarify with reason_code CONFLICTING_GROSS_PAY, citing R7 and R9.

Let me double check: R9 says amendment resolves conflict only if approved, effective month no later than payroll month, and amount equals payroll record's gross pay. Here amount 3807.00 equals payroll gross_pay, approved true, but effective month 2026-06 > 2026-04. So does not resolve. Clarify.

So answer: decision clarify, reason_code CONFLICTING_GROSS_PAY, clauses ["R7","R9"], explanation naming unresolved blocker.

The amendment's effective month is later than the payroll month, so it doesn't resolve. Need to ask for resolution — e.g., an approved amendment effective on or before 2026-04, or confirmation of which gross pay applies.

Include clauses R7 and R9.

The calculate tool errored because of the non-numeric lines. That's fine; I don't need it. The answer is a clarification.

Let me just produce the JSON.

Let me start by listing documents.

Read all three.

Payroll: gross_pay 3807.00, month 2026-04, allowed_deduction 181.70.

Contract gross_pay 3807.01 differs from gross_pay 3807.00. Conflict under R7 step 4. Amendment: gross_pay 3807.00, approved true, effective_month 2026-06. Effective month must be no later than payroll month (2026-04). 2026-06 > 2026-04, so amendment is future → does not resolve conflict. So return clarify CONFLICTING_GROSS_PAY citing R7 and R9.

Wait, check: the amendment amount equals payroll gross pay (3807.00). But effective month is 2026-06, which is later than payroll month 2026-04. So it does not resolve. So unresolved conflict → clarify.

Let me double check R9: "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." Future amendment → doesn't resolve. So clarify.

Answer: decision clarify, reason_code CONFLICTING_GROSS_PAY, clauses R7, R9, explanation.

Let me start by listing documents.

Let me read all documents.

Let me analyze.

Payroll record: gross_pay 3807.00, payroll_month 2026-04, allowed_deduction 181.70.

Contract gross_pay: 3807.01 — differs from gross_pay 3807.00. So conflict.

Amendment: gross_pay 3807.00, approved true, effective_month 2026-06. Payroll month is 2026-04. Amendment effective month 2026-06 is later than payroll month 2026-04, so it does NOT resolve the conflict (must be no later than payroll month).

So unresolved contract conflict → clarify with reason_code CONFLICTING_GROSS_PAY, citing R7 and R9.

Wait, let me double check the order in R7. Steps 1-3 are missing gross_pay, missing payroll_month, no applicable reference. Step 4 is the conflict. All present here, so we reach step 4.

Contract gross_pay 3807.01 differs from gross_pay 3807.00. Neither source takes precedence unless an approved amendment resolves it under R9. The amendment is approved but effective_month 2026-06 is after payroll month 2026-04, and its amount equals payroll gross pay (3807.00). But effective month is later, so it does not resolve. So return clarify CONFLICTING_GROSS_PAY citing R7 and R9.

Let me verify the reference row exists for 2026-04, but that doesn't matter for the conflict. Actually the order: step 3 checks month without reference row before step 4. Let me check reference to confirm 2026-04 has a row. If no row, we'd return NO_APPLICABLE_REFERENCE first. Let me look up.

2026-04 is first half presumably (Jan-Jun). Let me check.

2026-04 is within first-half (2026-01 to 2026-06). So a reference row exists.

Now the conflict: contract gross_pay 3807.01 vs payroll gross_pay 3807.00. Amendment approved, effective 2026-06 which is later than payroll month 2026-04 → does not resolve. So CONFLICTING_GROSS_PAY.

Return clarify with reason_code CONFLICTING_GROSS_PAY, citing R7 and R9, plus short explanation.
