Wien's Law Peak Wavelength 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

Unspecified domain and unit handling produce undefined results at 0 K, overflow at extremely small positive temperatures, a rejected negative-temperature branch, and radically different results when 0 is interpreted as Celsius versus Kelvin.

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.
