Let me start by listing documents.

Let me read all documents.

The payroll record has gross_pay 4188.34, payroll_month 2026-04, allowed_deduction 161.97.

Contract gross_pay 4163.34 differs from gross_pay 4188.34. So conflict. Amendment: gross_pay 4218.34, effective_month 2026-02, approved true. But amendment amount must equal the payroll record's gross pay to resolve conflict. 4218.34 ≠ 4188.34. So amendment does not resolve. So CONFLICTING_GROSS_PAY.

Wait, let me 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." Amendment amount 4218.34 vs payroll gross 4188.34. Not equal. So does not resolve. Return clarify CONFLICTING_GROSS_PAY citing R7 and R9.

Let me double check order of checks: gross_pay present, payroll_month present, month has reference row (2026-04, need to check reference). Actually check 3 before 4. Let me check reference rows.

Actually R7 order: 1 missing gross_pay, 2 missing payroll_month, 3 month without reference row, 4 conflict. So I must verify month 2026-04 has a reference row before returning conflict. Let me lookup reference.

But which reference table? First-half or second-half? 2026-04 is April, first half. Let me look up both maybe. The reference schedule covers months. Let me check.

2026-04 falls in first-half (2026-01 to 2026-06). So reference row exists. Good.

Now conflict: contract gross 4163.34 vs gross 4188.34 differ. Amendment doesn't resolve (amount 4218.34 ≠ 4188.34). So return clarify CONFLICTING_GROSS_PAY, citing R7 and R9.

Let me read the documents.

Payroll month: 2026-04. Gross pay: 4188.34. Contract gross pay: 4163.34. Conflict exists (4163.34 != 4188.34). Amendment: gross_pay 4218.34, effective_month 2026-02 (<= 2026-04), approved true. But amendment amount must equal the payroll record's gross pay to resolve. 4218.34 != 4188.34. So amendment does not resolve. Therefore CONFLICTING_GROSS_PAY clarification.

Wait, let me re-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."

Amendment amount 4218.34 vs payroll gross 4188.34 — not equal. So it does not resolve. So return clarify, reason_code CONFLICTING_GROSS_PAY, citing R7 and R9.

Let me double check the order in R7: step 4 is the conflicting gross pay. Steps 1-3 don't apply (gross_pay present, payroll_month present, month covered by reference row 2026-04 presumably). So we go to step 4.

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

Let me verify month is covered via reference - not strictly needed but let me confirm the reference exists for 2026-04. Actually step 3 says a month without a reference row. 2026-04 should have one. Let me check to be safe. But it doesn't matter much for the answer since conflict resolution takes priority only after step 3. Actually order matters: step 3 comes before step 4. If 2026-04 had no reference row, we'd return NO_APPLICABLE_REFERENCE. Let me verify.

Let me look up references.

2026-04 is covered by first-half (months 2026-01 through 2026-06). So reference row exists.

Now conflict: contract gross 4163.34 != payroll gross 4188.34. Amendment approved, effective 2026-02 <= 2026-04, but amount 4218.34 != 4188.34. So does not resolve. Return clarify CONFLICTING_GROSS_PAY citing R7 and R9.

Let me read all documents.

Payroll month 2026-04, first half (Jan-Jun). Let me lookup reference first-half.

Contract gross pay 4163.34 differs from payroll gross pay 4188.34. Amendment: gross_pay 4218.34, effective 2026-02 (≤ 2026-04), approved true, but amount 4218.34 ≠ payroll gross pay 4188.34. So amendment does not resolve conflict. Return clarify CONFLICTING_GROSS_PAY citing R7 and R9.

Wait, let me double check. The amendment must equal the payroll record's gross pay to resolve. 4218.34 ≠ 4188.34. So unresolved conflict → clarify.

Let me verify reference row exists though - not needed for clarification. Actually the conflict check is step 4, after month check. Month 2026-04 is covered by first-half. So conflict is the blocker.

Return decision clarify, reason_code CONFLICTING_GROSS_PAY, clauses R7, R9. Include explanation.

Let me not include monetary fields.

Payroll month 2026-04 is covered. Gross pay exists. Contract gross pay 4163.34 differs from 4188.34. Amendment gross 4218.34 ≠ 4188.34, so it doesn't resolve. → clarify CONFLICTING_GROSS_PAY, R7 & R9.
