Let me work through this payroll case.

Inputs:
- payroll record: gross_pay "3418.55", payroll_month "2026-10", allowed_deduction "361.73"
- contract gross_pay "3518.55" — differs from payroll gross_pay, so conflict check R7 step 4.
- amendment: gross_pay "3418.55", effective_month "2026-10", approved: false.

R9: Amendment resolves a conflict only if approved, effective month <= payroll month, and amount equals payroll gross pay. Here approved is false — so it does not resolve the conflict. Therefore we have an unresolved contract conflict → decision: clarify, reason_code: CONFLICTING_GROSS_PAY, citing R7 and R9.

Wait — but let me double-check. The conflict arises because contract_gross_pay differs from gross_pay. The amendment is not approved, so it doesn't resolve. So according to R7.4: "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 decision: clarify and reason_code: CONFLICTING_GROSS_PAY, citing R7 and R9."

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

For clarification, include a short explanation naming the unresolved blocker and asking for its resolution.

The schedule exists but since we can't calculate, we don't return monetary fields. The suggested-path... Actually per R7, for these cases do not return calculated monetary fields. We should not calculate.

JSON output:
{
  "decision": "clarify",
  "reason_code": "CONFLICTING_GROSS_PAY",
  "clauses": ["R7", "R9"],
  "explanation": "..."
}

The explanation should name the unresolved blocker: contract gross pay 3518.55 differs from payroll gross pay 3418.55, and the amendment is not approved, so the conflict cannot be resolved.

Note: allowed_deduction 361.73 is within second-half cap 400.00 (case schedule) and gross minus contribution... but irrelevant since we clarify.

Also note the trap: someone might apply the amendment anyway. But approved: false → does not resolve. Also effective_month is fine, amount matches, but approval is required.

So final answer.

Let me work through this payroll case.

Inputs:
- Payroll record: gross_pay "3418.55", payroll_month "2026-10", allowed_deduction "361.73"
- Contract: gross_pay "3518.55"
- Amendment: gross_pay "3418.55", effective_month "2026-10", approved: false
- Authoritative case reference schedule given (replaces defaults):
  - second-half (2026-10 falls in 2026-07 through 2026-12): rate 0.04, cap 4000.00, deduction cap 400.00, free 1100.00, upper 2800.00, middle_rate 0.14, upper_rate 0.22

Step 1: Check R7 in order.
1. gross_pay present: yes.
2. payroll_month present: "2026-10", valid format YYYY-MM, year 2026 within 2000-2099; covered by second-half row.
3. Reference row exists (case schedule covers second-half). Good.
4. contract_gross_pay present and differs from gross_pay (3518.55 vs 3418.55). Check R9: amendment resolves conflict only if approved (true), effective month ≤ payroll month, and amount equals payroll record's gross pay. Here approved is false → amendment does not resolve conflict. So we have an unresolved contract conflict → clarify with reason_code "CONFLICTING_GROSS_PAY", citing R7 and R9.

Wait — rule 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 decision: clarify with reason_code CONFLICTING_GROSS_PAY, citing R7 and R9."

The amendment is not approved (approved: false), so it does not resolve the conflict. So the answer is clarify.

Per R7: "For these cases do not return calculated monetary fields." And the answer format: clarify uses decision, reason_code, clauses. Include a short explanation naming the unresolved blocker and asking for its resolution.

Clauses: R7 and R9. Maybe also R1? The rule says "Unresolved contract conflicts cite R7 and R9." So clauses: ["R7", "R9"].

Output JSON:
{
  "decision": "clarify",
  "reason_code": "CONFLICTING_GROSS_PAY",
  "clauses": ["R7", "R9"],
  "explanation": "..."
}

Explanation should name the unresolved blocker: contract gross pay 3518.55 differs from payroll gross pay 3418.55, and the amendment is not approved, so it cannot resolve the conflict. Ask for an approved amendment or corrected records.

Do not include monetary fields. Only decision, reason_code, clauses, plus optional explanation.

Let me work through this payroll case.

Inputs:
- Payroll record: gross_pay = 3418.55, payroll_month = 2026-10, allowed_deduction = 361.73
- Contract: gross_pay = 3518.55 (differs from payroll record's 3418.55)
- Amendment: gross_pay = 3418.55, effective_month = 2026-10, approved = false

Reference schedule supplied:
- first-half: rate 0.05, cap 4000.00, deduction 400.00, free 1100.00, upper 3000.00, middle_rate 0.14, upper_rate 0.18
- second-half: rate 0.04, cap 4000.00, deduction 400.00, free 1100.00, upper 2800.00, middle_rate 0.14, upper_rate 0.22

Payroll month 2026-10 → second-half row: rate 0.04, cap 4000.00, deduction cap 400.00, free 1100.00, upper 2800.00, middle 0.14, upper 0.22.

Step 1: Check R7 order.
1. gross_pay present: 3418.55. OK.
2. payroll_month present: 2026-10. OK.
3. Month has reference row: 2026-10 is in second-half. OK. Also case schedule provided.
4. Contract conflict: contract_gross_pay 3518.55 differs from gross_pay 3418.55. Amendment present: gross_pay 3418.55, effective_month 2026-10 (no later than payroll month 2026-10 → yes, equal), approved = false. Amendment is NOT approved, so it does not resolve the conflict. Therefore decision = "clarify", reason_code = "CONFLICTING_GROSS_PAY", citing R7 and R9.

Wait — R7 item 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 decision: clarify and reason_code: CONFLICTING_GROSS_PAY, citing R7 and R9."

The amendment is false (draft/unapproved), so it does not resolve. So clarify with CONFLICTING_GROSS_PAY.

Also, R9: "A draft, future, or different-amount amendment does not resolve a conflict." The amendment is approved=false → draft, does not resolve.

Note: even though the amendment amount equals the payroll record's gross pay and effective_month equals payroll month, it's not approved, so it doesn't resolve.

Also note the allowed_deduction check: R4's cap. 361.73 ≤ 400.00 (second-half deduction cap from case schedule). Under R7 item "Monetary values present in a trap record must still obey R2 and the applicable deduction cap." But since we're clarifying due to conflict, we don't calculate. The order of checks: R7 lists 1-4 in order. Missing gross_pay, missing payroll_month, no reference row, conflicting gross_pay. The conflict is check 4.

Should I check deduction cap before conflict? R7 says check in this order: 1-4. The deduction cap issue isn't a clarification category listed. Here deduction is fine anyway (361.73 ≤ 400.00). Also "gross pay minus rounded employee contribution" — but we don't calculate employee contribution when clarifying. Anyway, the answer is clarify.

So the answer:
{
  "decision": "clarify",
  "reason_code": "CONFLICTING_GROSS_PAY",
  "clauses": ["R7", "R9"],
  "explanation": "The payroll record's gross pay (3418.55) conflicts with the contract's gross pay (3518.55). The amendment matching 3418.55 effective 2026-10 is not approved, so it does not resolve the conflict under R9. Please supply an approved amendment (with matching amount and effective month no later than the payroll month) or otherwise resolve the gross pay discrepancy."
}

Citations: unresolved contract conflicts cite R7 and R9. So clauses: ["R7", "R9"].

The explanation should name the unresolved blocker and ask for its resolution.

No monetary fields should be returned. Do not include input-only fields.

Final JSON:
