Let me process this payroll record.

Inputs:
- gross_pay: 3260.87
- payroll_month: 2026-08
- allowed_deduction: 0.00
- contract gross_pay: 3260.87 (matches, so no conflict, no amendment needed)

Case reference schedule:
- second-half (2026-07 through 2026-12): rate 0.08, cap 5000.00, deduction 400.00, free 1100.00, upper 3000.00, middle_rate 0.10, upper_rate 0.22

Calculation:
1. Employee contribution (R3): rate 0.08 × min(3260.87, 5000.00) = 0.08 × 3260.87 = 260.8696 → 260.87 (rounded half-up to 2 decimals)

Let me compute: 3260.87 × 0.08 = 260.8696. Round to 260.87.

2. Allowed deduction check (R4): 0.00 ≤ 400.00 cap and ≤ gross - contribution = 3260.87 - 260.87 = 3000.00. Valid. allowed_deduction = 0.00.

3. Taxable pay (R4): 3260.87 - 260.87 - 0.00 = 3000.00.

4. Income tax (R5): progressive marginal:
- Free amount: 1100.00 → untaxed
- Middle portion: from 1100 to upper 3000: 3000.00 - 1100.00 = 1900.00 × 0.10 = 190.00
- Upper portion: above 3000: 3000.00 - 3000.00 = 0 → 0.00
- Total tax: 190.00

5. Net pay (R6): 3260.87 - 260.87 - 0.00 - 190.00 = 2810.00

Check: 3260.87 - 260.87 = 3000.00; 3000.00 - 190.00 = 2810.00.

Fields:
- decision: "calculate"
- currency: "LCR"
- gross_pay: "3260.87"
- employee_contribution: "260.87"
- allowed_deduction: "0.00"
- taxable_pay: "3000.00"
- income_tax: "190.00"
- net_pay: "2810.00"
- clauses: R1, R2, R3, R4, R5, R6 (also schedule mention). Calculated answers cite R1 through R6. No amendment needed since contract matches gross_pay exactly, so R9 not cited.

Note: The case schedule says the schedule's numeric values replace defaults for that case. So second-half row: rate 0.08, cap 5000.00, deduction 400.00, free 1100.00, upper 3000.00, middle 0.10, upper 0.22.

Taxable pay: 3000.00 exactly equals the upper boundary 3000.00. Portion above upper boundary = 0. Portion between free (1100) and upper (3000): taxed at middle rate 0.10: 1900 × 0.10 = 190.00. Correct.

Contribution: 0.08 × 3260.87 = 260.8696 → round half-up → 260.87. Yes.

Net pay: 3260.87 - 260.87 - 0.00 - 190.00 = 2810.00.

Let me process this payroll record.

Inputs:
- gross_pay: 3260.87
- payroll_month: 2026-08
- allowed_deduction: 0.00
- contract_gross_pay: 3260.87 (matches, so no conflict)
- Case reference schedule provided: second-half row applies for 2026-08.

Second-half values from the authoritative schedule:
- rate: 0.08
- cap: 5000.00
- deduction: 400.00
- free: 1100.00
- upper: 3000.00
- middle_rate: 0.10
- upper_rate: 0.22

Calculations:
1. Employee contribution = rate × min(gross_pay, cap) = 0.08 × min(3260.87, 5000.00) = 0.08 × 3260.87 = 260.8696 → round to 260.87.

2. Allowed deduction: 0.00. Check: ≤ deduction cap 400.00 ✓; ≤ gross_pay − contribution = 3260.87 − 260.87 = 3000.00 ✓.

3. Taxable pay = gross − contribution − deduction = 3260.87 − 260.87 − 0.00 = 3000.00.

4. Income tax (marginal):
- Tax-free amount: 1100.00
- Upper bracket begins: 3000.00
- Middle rate: 0.10
- Upper rate: 0.22

Taxable pay = 3000.00.
- First 1100.00: untaxed → 0
- 1100.00 to 3000.00: 1900.00 × 0.10 = 190.00
- Above 3000.00: 0 × 0.22 = 0
Total tax = 190.00.

5. Net pay = 3260.87 − 260.87 − 0.00 − 190.00 = 1810.00.

Check: 3260.87 − 260.87 = 3000.00; 3000.00 − 190.00 = 1810.00.

Answer fields:

Let me process this payroll record.

Inputs:
- gross_pay: "3260.87"
- payroll_month: "2026-08"
- allowed_deduction: "0.00"
- contract gross_pay: "3260.87" — matches, so no conflict, no amendment needed.

Payroll month 2026-08 → second-half row. The authoritative case schedule is provided, so its values replace defaults:
- second-half: rate 0.08, cap 5000.00, deduction 400.00, free 1100.00, upper 3000.00, middle_rate 0.10, upper_rate 0.22

Steps (R1-R6):

1. Employee contribution (R3): rate × min(gross, cap) = 0.08 × min(3260.87, 5000.00) = 0.08 × 3260.87 = 260.8696 → round to 260.87.

2. Allowed deduction (R4): 0.00. Check: ≤ deduction cap 400.00 ✓; ≤ gross − rounded contribution = 3260.87 − 260.87 = 3000.00 ✓.

3. Taxable pay (R4): 3260.87 − 260.87 − 0.00 = 3000.00.

4. Income tax (R5), brackets for second-half:
   - Tax-free: 1100.00 → 0 tax
   - Middle band: from 1100.00 to 3000.00 = 1900.00 × 0.10 = 190.00
   - Upper band: above 3000.00 = taxable pay is exactly 3000.00, so nothing above. Tax = 190.00
   - Total: 190.00 → rounded 190.00.

5. Net pay (R6): 3260.87 − 260.87 − 0.00 − 190.00 = 2810.00.

Check: 3260.87 − 260.87 = 3000.00; 3000.00 − 190.00 = 2810.00.

Should I include an explanation? Optional. I can include a brief explanation noting the case schedule's second-half row used. But the instructions say "Do not include input-only fields such as payroll_month..." — explanation is permitted optionally. I'll include a brief one.
