Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Effect

Computation or source lookup only

Input and validation requirements

The specified calculations expose undefined results at sales = 0 for effective rate and quota = 0 for quota attainment. Negative sales also produce materially different results depending on the unstated sign convention.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.

{
  "inputs": {
    "plan_type": "flat",
    "sales": 125000,
    "rate_decimal": 0.04,
    "quota": 100000,
    "currency": "USD"
  },
  "expected_outputs": {
    "total_commission": 5000,
    "effective_rate_decimal": 0.04,
    "quota_attainment_percent": 125
  },
  "working": "Commission = sales × rate = 125000 × 0.04 = 5000 USD. Effective rate = commission ÷ sales = 5000 ÷ 125000 = 0.04 = 4%. Quota attainment = 100 × sales ÷ quota = 100 × 125000 ÷ 100000 = 125%."
