# Coriolis Deflection Estimator implementation

A source-bound implementation contract for Coriolis Deflection 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**: t5-151

**Effect**: Computation or source lookup only

## Input and validation requirements

The scalar formula can compute a magnitude or signed latitude-dependent scalar, but it cannot uniquely compute a physical deflection direction without an explicit velocity-bearing convention. The instrument must also suppress hemisphere direction labels when velocity is exactly zero and handle extreme finite inputs without overflow.

## 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.
