Stefan-Boltzmann Radiated Power Calculator implementation

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 intensity calculation is undefined for zero area because it evaluates 0/0, so the instrument must reject A=0 for intensity. The specification also leaves temperature-unit conventions implicit, allowing a severe Celsius-versus-kelvin misinterpretation.

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.
