Ideal/Adjusted Body Weight 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.

Computation or source lookup only

Input and validation requirements

The extreme-magnitude vector produces Infinity and NaN through floating-point overflow and Infinity plus negative Infinity. The convention probe also exposes an input-validation hazard when height units are omitted or ambiguous.

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.
