Candy/Sugar Syrup Stage Reference 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.

Input and validation requirements

An extreme but numerically valid elevation produces negative target temperatures, while the specification provides no input validation, altitude validity limit, clamping behavior, or defined result for that case. The abbreviated data table also leaves intermediate temperatures such as 241-244°F unspecified.

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.
