lookup_reference(reference="first-half")Reasoning
The payroll record: gross_pay = 3941.14, payroll_month = 2026-03, allowed_deduction = 197.94. Contract gross_pay = 3941.14 — matches, no conflict. Payroll month 2026-03 is in the first half of 2026. I need to look up the reference row. The rules say reference rows are available only through lookup_reference. Let me call lookup_reference for "first-half" (2026-03 is January–June presumably).

Month 2026-03 falls in the first-half reference row (2026-01 to 2026-06). Now I'll compute the exact figures.
Reasoning
The first-half row covers 2026-01 through 2026-06. Payroll month 2026-03 is covered. Reference row: - rate = 0.05 - cap = 5000.00 - deduction cap = 400.00 - free = 900.00 - upper = 3300.00 - middle_rate = 0.14 - upper_rate = 0.22 Inputs: - gross_pay = 3941.14 - allowed_deduction = 197.94 (≤ 400.00 cap; also ≤ gross_pay − contribution) - payroll_month = 2026-03 ✓ Calculations: 1. Employee contribution = 0.05 × min(3941.14, 5000.00) = 0.05 × 3941.14 = 197.057 → round half up to 197.06. 2. Allowed deduction check: 197.94 ≤ 400.00 ✓. Also must not exceed gross pay minus rounded contribution: 3941.14 − 197.06 = 3744.08. 197.94 ≤ 3744.08 ✓. 3. Taxable pay = 3941.14 − 197.06 − 197.94 = 3546.14. 4. Income tax: - Free portion: 900.00 → 0 tax. - Middle bracket: 3300.00 − 900.00 = 2400.00 × 0.14 = 336.00. - Upper bracket: 3546.14 − 3300.00 = 246.14 × 0.22 = 54.1508 → but don't round intermediate products; sum then round: 336.00 + 54.1508 = 390.1508 → round to 390.15. 5. Net pay = 3941.14 − 197.06 − 197.94 − 390.15 = 3155.99. Let me verify: 3941.14 − 197.06 = 2744.08. 2744.08 − 197.94 = 2546.14. Wait, that's taxable pay? Let me recompute: 3941.14 − 197.06 − 197.94 = 3941.14 − 395.00 = 2546.14. Hmm, I made an arithmetic error earlier. Let me redo. 3941.14 − 197.06 = 2744.08. 2744.08 − 197.94 = 2546.14. So taxable pay = 2546.14, not 3546.14. Good catch. Income tax on 2546.14: - Free: 900.00 → 0. - Middle: 2546.14 − 900.00 = 1646.14 (since 2546.14 ≤ 3300.00, entire amount above free is in middle bracket). 1646.14 × 0.14 = 230.4596 → round to 230.46. - Upper bracket: none. Income tax = 230.46. Net pay = 3941.14 − 197.06 − 197.94 − 230.46 = 3315.68. Check: 3941.14 − 197.06 = 2744.08; − 197.94 = 2546.14; − 230.46 = 3315.68. Let me use the calculate tool for exact decimal arithmetic as instructed. Program: contribution = round(min(5000.00, 3941.14) * 0.05, 2) available = 3941.14 - contribution taxable = 3941.14 - contribution - 197.94 middle_portion = max(0, min(taxable, 3300.00) - 900.00) upper_portion = max(0, taxable - 3300.00) tax = round(middle_portion * 0.14 + upper_portion * 0.22, 2) net = 3941.14 - contribution - 197.94 - tax Let me run this.

All checks pass: the deduction 197.94 is within the 400.00 cap and below the available pay (3744.08), and the contract gross pay matches the payroll record, so no amendment is needed.

Reasoning
Wait, the calculator returned taxable = 3546.14. Let me check my manual arithmetic: 3941.14 − 197.06 = 2744.08. Then 2744.08 − 197.94 = 2546.14. But the calculator says 3546.14?
Hmm, let me recompute: 2744.08 − 197.94. 2744.08 − 197.94 = 2546.14. So the calculator result of 3546.14 seems wrong... unless I made an arithmetic error.
3941.14 − 197.06: 3941.14 − 197 = 3744.14; minus 0.06 = 3744.08. Yes, available = 3744.08 matches.
3744.08 − 197.94: 3744.08 − 197 = 3547.08; minus 0.94 = 3546.14.
Oh wait, I made an error earlier! 3941.14 − 197.06 = 3744.08, not 2744.08. Let me redo: 3941.14 − 197.06. 3941 − 197 = 3744. So 3744.08. Yes, I dropped a thousand earlier. So taxable = 3546.14 is correct.
So taxable = 3546.14, which exceeds upper = 3300.00. Middle portion = 3300 − 900 = 2400.00 × 0.14 = 336.00. Upper portion = 3546.14 − 3300 = 246.14 × 0.22 = 54.1508. Sum = 390.1508 → 390.15. Tax = 390.15.
Net = 3941.14 − 197.06 − 197.94 − 390.15 = 3155.99. Check: 3941.14 − 197.06 = 3744.08; − 197.94 = 3546.14; − 390.15 = 3155.99. ✓
All checks:
- Contribution: 0.05 × min(3941.14, 5000.00) = 197.057 → 197.06 ✓
- Allowed deduction 197.94 ≤ cap 400.00 ✓ and ≤ available 3744.08 ✓
- Taxable pay = 3546.14
- Tax: free 900 untaxed; middle 2400.00 × 0.14 = 336.00; upper 246.14 × 0.22 = 54.1508; total 390.1508 → 390.15 (rounded once at the end per R5)
- Net = 3155.99

The first-half reference row applies to 2026-01 through 2026-06. Payroll month 2026-03 is covered. Row values: - rate: 0.05 - cap: 5000.00 - deduction cap: 400.00 - free: 900.00 - upper: 3300.00 - middle_rate: 0.14 - upper_rate: 0.22 Now compute: 1. Employee contribution (R3): rate × min(gross, cap) = 0.05 × min(3941.14, 5000.00) = 0.05 × 3941.14 = 197.057 → round to 197.06. 2. Allowed deduction check (R4): allowed_deduction = 197.94. Must not exceed deduction cap (400.00) or gross pay minus rounded contribution (3941.14 − 197.06 = 3744.08). 197.94 ≤ 400.00 ✓ and ≤ 3744.08 ✓. So allowed_deduction = 197.94. 3. Taxable pay (R4): gross − contribution − deduction = 3941.14 − 197.06 − 197.94 = 3546.14. 4. Income tax (R5): progressive: - Up to 900.00: free → 0 - 900.00 to 3300.00: 2400.00 × 0.14 = 336.00 - Above 3300.00: 3546.14 − 3300.00 = 246.14 × 0.22 = 54.1508 - Total: 336.00 + 54.1508 = 390.1508 → round to 390.15. 5.

The contract gross pay (3941.14) matches the payroll record, so no amendment is needed. Now let me compute the exact figures.
Reasoning
The first-half row covers months 2026-01 through 2026-06, so 2026-03 is covered. Parameters: - contribution rate: 0.05 - wage cap: 5000.00 - deduction cap: 400.00 - tax-free: 900.00 - upper bracket boundary: 3300.00 - middle rate: 0.14 - upper rate: 0.22 Inputs: - gross_pay = 3941.14 - allowed_deduction = 197.94 - contract gross pay matches (3941.14), no conflict. Calculations: 1. Employee contribution = 0.05 * min(5000.00, 3941.14) = 0.05 * 3941.14 = 197.057 → round half up to 197.06. 2. Allowed deduction check: must not exceed deduction cap (400.00) or gross pay minus rounded contribution (3941.14 - 197.06 = 3744.08). 197.94 ≤ both, so valid. 3. Taxable pay = 3941.14 - 197.06 - 197.94 = 3546.14. 4. Income tax: - Free portion: 900.00 untaxed. - Middle bracket: 3300.00 - 900.00 = 2400.00 at 0.14 = 336.00. - Upper bracket: 3546.14 - 3300.00 = 246.14 at 0.22 = 54.1508. - Total = 336.00 + 54.1508 = 390.1508 → round to 390.15. 5. Net pay = 3941.14 - 197.06 - 197.94 - 390.15 = 3155.99. Let me verify with the calculator.

Reasoning
All values check out: - Employee contribution: 0.05 × 3941.14 = 197.057 → 197.06 - Allowed deduction 197.94 ≤ 400.00 cap and ≤ 3744.08 available pay — valid - Taxable pay: 3941.14 − 197.06 − 197.94 = 3546.14 - Tax: 900 free; (3300−900)×0.14 = 336.00; (3546.14−3300)×0.22 = 54.1508; total 390.1508 → 390.15 - Net pay: 3941.14 − 197.06 − 197.94 − 390.15 = 3155.99 Return the R6 JSON answer with clauses R1–R6.
