# Wave Energy Flux Estimator implementation

A source-bound implementation contract for Wave Energy Flux Estimator; deployment and executable qualification remain separate.

Status: **VERIFIED_CLEAN**Lifecycle: **implementation-contract**

## 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.

**Record owner**: Guth Instruments

**Lifecycle**: verified-clean

**Evidence ID**: t5-143

**Effect**: Computation or source lookup only

## Input and validation requirements

The plain-arithmetic implementation can overflow to Infinity for extreme finite inputs, and the specification provides no alternate formula or depth input for the shallow/intermediate-water branch even though the advertised formula is explicitly limited to deep water.

## 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.
